It was within the year of 1911, when W. H. Bill Hargreaves had discovered the first gold mine in the Kirkland Lake Mining Camp. He had additionally staked three mining claims prior to this discovery on July, 27, 28 and 29, 1911. There was also another claim that was staked by his brother Ed. Hargreaves, which became apart of this historical operation. Kirkland Lake Ontario, Canada was rather now becoming existent due to the outbreak of gold being discovered here. This resulted in claim staking frenzy which had many prospector in search for the rich gold ore, which had also been shipped from the Foster Property. Some of the heaviest development work was mainly confined to the Tough-Oak, which once consisted of five claim groups comprising of 40 acres each. By this time Mr. W. H. Bill Hargreaves had discovered a gold bearing quartz vein in Porphyry, and a two stage diamond drilling program was started.
1913 - Wright-Hargreaves Mine
It was in 1913, when another rich vein was discovered 550 feet north of the No. 2 Vein, while the property was under option to Mr. R. Cartwright.The very first shaft was then sunk on the vein to sixty feet, and had showed this vein to be 5 feet in width, and 3.5 tonnes of high-grade ore averaging $331.35 per ton. Prior to this the option was allowed to lapse, and it wouldn't be until 1916, when the property gained some more interest in developing it.
1916 - Wright-Hargreaves Mines, Ltd.
By 1916, the Wright-Hargreaves Mines, Ltd. was formed in order to develop this gold property for the first time. Prior to this the company had owned the following claims in Teck Township, which consisted of claim Nos. 708, 709, 710, and 711. Employment by November, 18, 1916, had consisted of 25 men that were confined to building the many structural buildings such as a plant, and the development of several of other much need structures. Even the main power line from Cobalt, Ontario, Canada was built which had provided the much needed power supply. With this taking place the company had also set up sinking equipment as the No. 2 Shaft became sunk to a depth of 25 feet, and the No. 3 Shaft had reach 100 feet. For the most part it was strongly reported that the company was being operated under the direction of Oliver Cabana as president, Edwin Lang Miller as Secretary Treasurer, and Gerhard F. Miller as manager.
1917- Wright-Hargreaves Mines, Ltd.
Development at the Wright-Hargreaves Gold Project was rather minimized within the year of 1917. Company officials from the Wright-Hargreaves Mines, Ltd had employed a workforce of 35 men. Most of this had resulted in continuous sinking as the No. 2 Shaft was now reaching 320 feet, and the No. 3 Shaft was extended to a depth of 300 feet. Even more machinery became added when the company had installed a new Ingersoll Rand Compressor, with a capacity of 1,165 cubic feet.
1918 - Wright-Hargreaves Mines, Ltd.
The company in 1918, was well establish with a capitalization of 2,500,000 shares at $1 par value. Mining operations within the year ofo 1918, were completely shut down due to the preparations developing a headframe, and a 150 ton milling facility. Before this shut down had occurred it was rather stated that the No. 1 shaft was sunk to a depth of 425 feet below the surface. Lateral development was also continued onward as the fourth level became extended by 600 feet of crosscutting towards the No. 1 Shaft. This also resulted in developing the 300 foot level of the No. 2 Shaft by 400 feet of drifting. No additional development was done prior to sinking the shafts, and extending the working in preparation to extract the gold ore.
1919 - Wright-Hargreaves Mines, Ltd.
No major work was done during 1919, as the company had focus on erecting the 60-foot head-frame, and a change house at the No. 3 Shaft. With this taking place the company had also turned to the preparations of building a 150-ton milling facility. Much of the ground for this development was completely excavated, and a stockpile of gold ore was awaiting to be treated. Employment within 1919, was known to have average a workforce of 55 men who became employed prior to the first strike action.
1920 - Wright Hargreaves Mines, Ltd.
All mining operations at the historical Wright-Hargreaves Mines, Were once again re-opened during the spring season of 1920. Shaft sinking had also continued as the No. 1 Shaft that was at a depth of 40-feet became sunk to 400 feet. With this taking place the company had also enlarge the No. 3 Shaft from two to three compartments. Most of this enlargement had also been extended from the 300-foot level to the surface within that year. Some work was also done on the 300-foot level when the working were extended by 110-feet of drifting. The 400-foot level was also being well developed by 175 feet of drifting, and 110-feet of crosscutting that was done in preparation for stoping. It was also at this time when most of the lateral work was aimed at connecting the No. 3 Shaft with the bottom of the No. 1 Shaft. Much of the on-site milling facility was also near completion, and was expected to be in operation by 1921.
1921 - Wright Hargreaves Mines, Ltd. -
Milling operations at the historical Wright-Hargreaves Mine had commence operation on May, 1st, 1921. From this time period it was stated that the 150-ton mill had treated 36,081 tonnes of ore, which produce a value of $468,665.64 in gold bullion. With the commencement of the mill it was rather stated that it had ran at 92% at the possible running time, and had treated a daily average of 175-tonnes per day. It was on May, 1st, 1921, when the broken ore had amounted to 2,000 tonnes, and by December,1st, 1921, the Broken Ore amounted to 25,085 tonnes. Prior to this the company would also add additions to the mill when a 650-cubic foot compressor, two air receivers, and an electric signal system was added. It was also within this time period when equipment for exhausting steam, and to return water to boilers was added.
Development work within 1921, was mainly focus on developing the No. 2 vein, and by August, 1st, 1921, the company had not done any work on the No. 1 Vein. As the mine slowly started to expand it was reported that the total lateral development footage completed to date was 2,908 feet.Development at the time had also resulted in several stop section that became developed within the Wright-Hargreaves Mine Site. The following shows the amount of broken ore that was taken from all five stope sections in 1921.
Stopes Length in feet Broken Ore in tons
400 East 470 feet 7,900 tonnes 400 West 260 feet 3,360 tonnes 300 East 230 feet 8,000 tonnes 200 East 240 feet 1,840 tonnes 200 West 100 feet 300 tonnes
1922 - Wright Hargreaves Mines, Ltd. - 36,521 ounces of gold (Au) and 4,866 ounces of silver (Ag)
For the most part the Wright-Hargreaves Mine is known to consist of three adjacent mining claims along the main fracture, and the fourth lying south of Sylvanite Gold Property. Exploratory work that was commenced from the surface, and under the bed of Kirkland Lake had exposed the No. 2 vein for length of 3,900 feet. So far to date it was rather the largest vein of any gold property in Kirkland Lake during 1922. Development was now being focus on the Westerly or No. 3 Shaft that was put down to 1,000 feet below the surface, and the No. 1 had only reach 300-feet. Another shaft known as the No. 2 shaft was additionally sunk on the No. 1 vein, and became connected with No. 3 main shaft on the 400 foot level. It was determined that the No. 3 shaft had been opened up on fracture within 8 producing levels at the time. Explorations during that year had continued onward but only a small portion of vein was explored at the time. Some of the greatest amount of work during this time period was confined to the 400-foot level where six stopes became opened up on the main vein. Development work that was done had mainly determined that this ore had occurred in shoots at various points on the vein. Stope sections within this time period had also been developed at various sections and acted as separate stopes. Stoping that was done during 1922, had average a total length of 320 feet, and one of the biggest ore shoots which lied east of the shaft had been traced to the 1,000-foot level. Anther large ore shoot that was disclosed to the west had rather been determined to have pinch to the east. This ore shoot has been faulted by a strong fault which had strike N 15 degrees E, and dip 75 degrees west. It was also determined that the westerly part of this shoot became displaced at a distance of 140 feet south, and work had indicated probable downward throw of 190 feet on the west side. Prior to this it was also stated by the company that a number of faults and slips are encounter within the Wright-Hargreaves workings. The most recent development during 1922 had disclosed a large vein by a crosscut on the 1,000 foot level of the No. 1 vein that traveled north. Compared to the No. 2 vein it was strongly stated that the No. 1 vein was less narrower, and was much higher in grade which opened up in a stope for a width of 5 feet. For the most part, this vein had showed visible gold and tellurites associations. All development that was undertaken had showed one ore shoot at the crosscut to be 165 feet in length, and the second one to the east was 400 feet in length with the east face in high-grade ore. Ore which had supplied the on-site milling facility was also taken from development, and shrinkage in stoping, and a large tonnage of broken ore was being extracted. Rocks which are exposed within the stopes are known to be feldspar porphyry, and conglomerate. It was also strongly reported that wedge of conglomerate had lied on the north side of the No. 2 vein near the No. 3 Shaft. Much of this conglomerate was determined to have also continued downward to the 500 foot level. At the 1,000-foot level it was also shown that the No. 1 vein was entirely in feldspar porphyry just like the No. 2 Vein Zone. Along the vein its also determined that the porphyry had often been sericitized, showing a light greenish colour of possible chlorine. Even milling during this time period became enlarged from 230 tonnes per day to 400 or 500 tonnes per day. Broken ore reserves within the Wright-Hargreaves Mine would also amount to 75,815 tonnes, and the grade had also increased to $15 a ton in 1922.
Milling during 1922 had end up treating a total of 66,181 tonnes of ore, and the bullion received had amounted to $762,752.84. At the time it was also determined that the broken ore on had during that year had amounted to 33,200 tonnes.All milling during 1922, had operated at 88.31% of its possible running time, and the 2.41% became shut down for repairs, and the remainder 9.28% was due to power lost from a Forrest fire. Heavy developmet at the time was focus on sinking the No. 3 shaft from 420 feet to a depth of 875 feet. Even new stations became cut at 550, 700, and 850-foot levels. At the 700-foot level a sump was cut, and a 4 by 6-foot triplex pump, with a capacity of 60-gallons per minute was installed against a 500-foot head. Drifting within that year was mainly confined to extending the 400 and 500-foot levels, which three-fourths of it was entirely in ore. Stoping was also carried on progressively, and a total of 45 box holes, and 50 chutes became opened up. A total of 5,863 feet of drifting, 678 feet of crosscutting, and 827 feet of diamond drilling was done.
Construction within 1922, was confined to erecting a bunk house with 40 sleeping rooms, which was 26 by 130-feet in measurement. Most of this was done in order to maintain the accommodations for 80 men at the No. 2 shaft operation of the Wright-Hargreaves Mine Project. Prior to this the company had also laid an underground water-main to all the buildings, and a grease trap, ad separate tanks were made.
1923 - Wright Hargreaves Mines, Ltd. - 36,370 ounces of gold (Au), and 4,968 ounces of silver (Ag)
Shaft sinking at the Wright-Hargreaves No. 3 shaft had continued onward when it sunk from 865 feet to the 1,020-foot level. As the shaft continued pass the 1,000 foot level a station became cut on the mines, 1000 foot section. Drifting at the time was also confined to the 800-foot level, and a total of 500 feet was done towards expanding this level. Stoping and drifting operations on the 700 foot level had also opened up much high grade ore then the upper levels. In addition to development, no lateral work was attempted on the newly stationed 1,000 foot level but was slowly progressing by the years end. It was also determined that this newly developed level had also showed high-grade ore just like the 700, and 800 foot levels. Only a small amount of development work was confined to the lower levels as most of it was done on the upper levels. Even further exploratory work was done when a diamond drill hole was driven north from the 1,000 foot level to intersect the No. 1 vein. Results from this drilling program had continued to outline positive results of high-grade milling ore. Another diamond drill holes was driven north on the 400-foot level that also intersected high-grade mill ore on the No. 1 vein. Further stoping was also carried onward which resulted in more broken ore, and most of the ore that was milled came from development. Drifting to the end of December had amounted to 9,159.6 feet, crosscutting had amounted to 829.6 feet, and 2,376.6 feet of diamond drilling was done.
Milling that was done during the year had also amounted to 79,249 tonnes, and the bullion received was $754,978.81. Broken ore reserves that were stockpile, and on hand had resulted in 75,815 tonnes, Milling in 1923 had operated at 94.32% of its possible running time, and no delays were encountered in production. Some more additions were made when a new set of crushing rolls were added to the crusher house equipment. More so this became very useful as it provided a much finer product to be treated at the on-site milling facility. At the time, it was also reported that the company had poured the much need concrete foundations in anticipation to increase milling rates.
1924 - Wright Hargreaves Mines, Ltd. - 52,464 ounces of gold (Au), and 6,413 ounces of Silver (Ag)
It was in 1924, when development was being confined to the lower workings of the historical Wright-Hargreave Mine Site. By June, 24, 1924, the company was well off with this development as it was decided to run a cross-cut on the 1,000 foot level of the No. 3 shaft to intersect the No.1 vein to the north. At about 575 feet it was strongly stated that this level had intersected with the vein on the 1,000-foot level. A total of 1,460 feet of drifting was done on the No. 1 vein in which 940 feet was entirely in good ore. Lateral development that was completed that year had resulted in 13,821 feet of drifting, 2,431 feet of crosscutting, and 2,516 feet of diamond drilling.
Production at the time was largely increased as the mill had treated 84,487 tonnes of ore, and the bullion recovered was at $1,088,725.53. Broken ore reserves that were stockpiled, and on hand had resulted in 118,331 tonnes. Milling operations in 1924, had operated at 93.10% of its possible running time, and was roughly treating 230 tonnes per day.
1925 - Wright Hargreaves Mines, Ltd - 92,286.28 ounces of gold (Au), and 8,519 ounces of silver (Ag)
Even further expanding continued onward when the No. 1 Shaft was sunk from the 700-foot level to a depth of 1,271 feet below the surface. With sinking taking place it soon became determined that the ore was of good grade, and still was unexplored at depth. It was even at this point in time when the No. 1 vein was opened up on the mines 400, 700, 850, and 1,125-foot levels.There was also a station on the 1,250 foot level that was recently cut, and a small amount of drifting had proven the ore to be the same grade as the upper levels. Another body that was located 40 feet south of the No. 1 shaft was also cut within the year of 1925. At the time, it was strongly reported that no drifting was done on this vein, but assays confirmed it to be satisfactory. Development which was done had became very encouraging as drifting on the No.1 vein was entirely in ore, and the ore opened up had been continuous, and consistent on this property. For the most part it was strongly reported that mining and development was mainly focus on the No. 1 or North Vein. It was at this point when a 500 foot crosscut was driven on the 700-foot level, which had connected with the No. 1 and No. 3 Shafts. By establishing this it had made three haulage ways between the No.1 and No. 2 ore-bodies. There was also even more development that was aimed at connecting the No. 1 and No. 2 shafts on the 1,250-foot level.
Some more installations were also made when an additional air compressor was added to provided 1,000 cubic feet of air per minute. Even more machinery was added to the underground workings in order to increase development, and production from the Wright-Hargreaves Mine Site. With the mine continuing to expand the company would also add a new hoist towards its underground operations in order to commence shaft sinking. There was also a second electric locomotive that was add for hauling ore from the underground workings to the hoisting compartment at the shaft.
Milling was also largely increased when it had treated a total of 147,939 tonnes of ore in 1925. It was rather by March, 1925, when milling was also increased to 400-tonnes of ore per day. By this time the company had rather ended up obtaining a bullion recovery of $1,913,401,82 from all production. Further so the on-site mill had rather treated a total of 413,930 tonnes that produce a bullion recovery of $4,988,524.64.
1926 - Wright Hargreaves Mines, Ltd - 103,793.12 ounces of gold (Au), and 8,912 ounces of silver (Ag)
Operations at the historical Wright-Hargreaves Mine had once again became extended as stoping was confined to the upper, and intermediate lower levels. Most of the development was confined to the North, and South veins, with the ongoing sinking to the lower level workings. It was within the North Break of the No. 1 shaft that sinking was continued onward to a depth of 1,500 feet. Prior to sinking it was also stated that stations became cut on mines 1,375, and 1,500-foot levels. A small amount of drifting was then establish which showed the continuity of the north vein which had the same high-grade ore as the upper levels, along with widths. Even more changes were made when a new headframe was at the No. 1 Shaft in order to accommodate the Norberg hoist.
Sinking would not stop here as the main shaft No. 3 on the south break was continued to a depth of 1,375 feet below the surface. This sinking phase had also resulted in the cutting and stationing of new levels at 1,125, 1,250, and 1,375-foot levels. Results of cutting, and stationing along with drifting on these levels had showed much higher-grade ore, and widths then that found on the 1,000 foot level. One of most significant stations at 1,375 feet had rather showed that the vein at this point had a width of 17 feet, and assayed $13.00 in gold per ton. A crosscut was also driven between the No. 1 and No. 2 shafts on the 1,250 foot level, and another crosscut was started on the 1,500-foot level to connect with the two shafts also. By this time the company had also constructed an ore-pocket on the 1,250 foot level, and the much need skips were being ordered
Milling operations had once again increased significantly when the company had treated 153,392 tonnes of ore in 1926. No additional efforts during that year were made to increase the tonnage milled per day but rather had been focus on studies in perfecting operations. A few changes were also made when a classifier was installed in order to return the coarse product to the ball mills, which increase the company's grading. One of the primary thickeners was also replace with super-thickener, that was aimed at increasing the primary thickening capacity. Even more studies were being made towards improving the flotation of tellurite ores to obtain better production capacity. As this occurred the company would also end up installing flotation cells, along with a roasting furnace to financially save a lot of capital in regards to concentrates. An addition was also made to the on-site mill building in order to accommodate the flotation equipment. Prior to this the company had also added another bullion furnace in order to double its capacity.
Construction at the time was mainly focus on increasing air, and hoisting capacity as the company was unable to do further exploratory work. Most of this became cause due to the depth of the mining project and a Norberg Hoist was then installed to eliminate this issue. With air also being a problem the company had also purchase 2,500 foot Bellis and Morcom Air Compressor to double the air capacity. It was also need to increase development, and exploration work as the Wright-Hargreaves Mine became a big mining operation. Most of this was cause because the company was working on doing further exploratory work on its east, and west side that adjoined the Sylvanite, and Lake Shore Mines. Other statements from the company had stated the both of these claims were rather large then the area it was working on. Even more additions were being completed when the power house had a new foundation for the 2,500 foot air compressor. A dry house was also enlarge during 1926, to accommodate the increasing number of workers.
1927 - Wright Hargreaves Mines, Ltd - 103,798.86 ounces of gold (Au), and 11,378 ounces of Silver (Ag).
By 1927, the company was well off with this operation when stoping was being done on the north and south veins, together with sinking, and exploring ground to the west of the previous working and adjoining west boundary. Prior to this the shaft on the North Break was continued onward when the company had reach a depth of 1,780 feet below the surface. Two stations were then cut in order to provide the necessary production for the on-site mill at 1,625, and 1,750 feet. A small opening of 30 feet of drifting was done on these levels in order to prepare it for the installation of guides, ladders, and pipes on the 1,750 foot level. Most of this became accomplish as the company had wanted to continue sinking the shaft to the 2,000 foot level.
It was also during 1927, when the South Break of the No. 3 Shaft or Main Shaft had continued onward to a depth of 1,500 feet. A loading pocket was then establish as the company was ready to install the much need skips to hoist the ore from the workings. Even more changes were made when a large double drum hoist with a 3,000 foot depth was installed on the main shaft to reach significant depths. At the time some more plans were also aimed at continuing the sinking phase of No. 3 shaft to a depth of 2,000 feet.
Almost 85% of all the ore that was extracted became mined from the center portion of the property, and adjacent to the No. 1 and 3 shafts. The remainder of the ore produce was also rather taken from the ground between the 400-foot level, and the No. 1 fault, of the No. 2 or South Break. A small amount of exploratory work was done on the west, and east claims which had adjoined the Lake Shore, and Sylvanite Mine Projects. A small exploration program was also aimed at exploring this ground from the 1,250-foot level on both veins. In addition to this, the work was rather carried out to a limited degree on the west claim of the property boundary. Some more issues had rise when the company had encountered several faulting problems but had fast track to become very knowledgeable with these structures. Much of the east end was also unexplored at this time so a detailed mapping phase could not be done on it. Shaft sinking was also continued onward as the company wanted them to reach depths of 2,000 feet by August, 1927. Other intentions were aimed at further exploring the east claims which had lied between the central workings, and sylvanite boundary, and to carry out extensive development on the west claim. It appear that the company was well below the fault zone in this area, and had predicted that the production and grading would improve. Drifting during 1927, had amounted to 32,259.5 feet, while crosscutting had amounted to 4,491.5 feet, and diamond drilling to 14,923.5 feet.
Even milling operations during that time period of operating were now increased as the company had treated 209,164 tonnes of ore. By this time the total bullion which was recovered from production had amounted to $2,151,919.24. Milling which was done had operated at 94.78%, and had treated an average of 573 tonnes of ore per day. Total production from 1922 to 1927 had produce a total bullion of $9,291,284.80, from 776.286 tonnes of ore.
1928 - Wright Hargreaves Mines, Ltd - 88,580.07 ounces of gold (Ag), and 12,778 ounces of silver (Ag)
1928 was rather another high end production year for the Wright-Hargreaves Gold Mine. Most of all the development which was completed became focus on the No. 1 vein, and south or No. 2 vein zone between the two major fault structures. Statements on the No. 2 vein had stated that this area had produce some of the best values within the property on the 700-foot level. Other statements had stated that the ore mined below this horizon had produce $6 to $7 a ton. Other reports had stated that the much higher grade ore of the No. 1 vein had also been mixed in with the No. 2 vein, which also produce a better grade of ore for the mill. Ore that was extracted from the No. 1 vein was rather in the shape of a lens with the top 500-feet below the surface, and with its greatest length on the 1,125-foot level, where it was 1,100 feet long. It appeared that the lens had bottomed between the 1,750, and 1,875 foot levels. By this time the bottom and end of this lens was also reported to have became so narrow, that with dilution it did not improve the mill feed from the No. 2 vein. As sinking had reach the 2,000-foot level the company had also discovered a new vein following development on this section. It was also considered to have been different in characteristics, and had dip to the south in contrast with the No. 1 vein zone, which was a vertical one. Development which took place had opened up this vein for a distance of 700 feet, in which 540 feet was entirely in good ore.
Within this time period it was also stated that another vein was opened up on the 1,250-foot level, and had the same similar characteristics on the east.claim for 800 feet. Almost 550 feet of this length had provided the much need stoping ground for production, and could potentially add more length during prospecting in 1927. A present time the east heading was entirely in ore but was much narrower then that already opened up. Other statements had reported that this east drive had 125 feet to go before reaching the mine boundary. Some more conclusions were made when the ore-body was also opened up on the 1,500 foot level on the east claim, and a crosscut on the 1,375-foot level had 200 feet to go before reaching it. Ore that was opened up at the time was not made certain that it had a connection with the 2,000-foot level in the central claim. Further work on the east claim was rather need in order to determine if the ore-body is similar to that on the 2,000-foot level. A loading pocket was also installed in the No. 3 shaft below the 2,000-foot level, and transformers, pumps, and charging stations were built. At the time, it was also stated that both shafts were well sunk below the 2,000 foot level as the No. 1 had reach 2,030 feet, and the No. 3 had reach 2,100 feet. Most of the work that was completed had also provided the need for more compress air in order to maintain development, and to continue on with exploratory work the east, and west. It was rather the east drives that had shown much better results from explorations then those obtained in the west drive. In addition to the ore being developed on northeast of the property, a new ore shoot was being opened up on the 1,750 foot level, thats located 1,000 feet east of the No. 3 shaft and paralleling to the No. 2 vein. At the time it was only opened up for 65 feet and had showed an average value of $15 per ton over the whole width of the drift section. Drifting on this section had continued to the east, and had also showed the same resemblance of the ore occurring in the north vein series rather that of No. 2 vein. Crosscutting was then commenced on this level to cut what was known as the easterly extension of the No. 2 vein which also east of a fault that throws it to the south 110 feet. For the most part, this crosscut was rather reported to have been located 1,050 feet east of the No. 3 shaft. Ore values to the shaft on the south vei on the 1,875, and 2,000-foot levels have not shown any improvements over intermediate levels. However, some diamond drilling which was undertaken had proven to shown high-grade ore grades on the 2,000-foot level to the east of the shaft, and 60 feet north of the present drift which followed one of the fractures composing the No. 2 vein series. Drifting at the time was also proceeding onward on the south or No. 2 vein zone from the No. 3 Shaft, on the 400, 1,000, 1,175, and 2,000 foot level. Much of these drives were being extended in order to explore the easterly continuation of the Lake Shore North Vein, which became displaced northward for about 550 feet by a large fault occurring the west section of the property. Further examinations had reveal that it corresponds with the north vein on the central portion of the Wright-Hargreaves Property. By this time, the company had rather focus on exploring this vein from the No. 3 shaft as it was located close to it. Lateral development had also became so extensive within this time period as 44,240.5 feet of drifting, 7,378 feet of crosscutting, and 28,384.5 feet of diamond drilling was done.
Milling was rather continuous throughout the year with the exception of unfavorable shut downs due to power failures, and repairs. Some minor changes were rather made to the milling facility in order to increase milling efficiency towards its process. Most of the changes made were being done on clarifying and flotation method during 1928. It was also at this time when the capacity of the mill was a large factor in order to contribute to the speed and economical development of the mine. Prior to this it was also considered that this would make all ore encountered during drifting profitable in obtaining all the gold at lower milling costs. Most of the ore that was mine in 1928 was also considered as low grade ore, and that any smaller tonnage could result in a decrease of gold (Au) production. It was also within 1928, when the company would end up treating 256,331 tonnes of ore, which produce a bullion recovery of $1,845,923.74 An increase was also made within this time period as the ore had average 7.20 per ton, and was milled at a daily rate of 700 tonnes per day.
1929 - Wright Hargreaves Mines, Ltd - 83,631.42 ounces of gold (Au), and 11,323 ounces of silver (Ag).
Milling during 1929, was discontinued as the company was once again was on a mission to increase available ore reserves in the Wright-Hargreaves Mine. It was also within this time period when the company was focusing on using all the available resources in developing any possible new ore, and at the same time it was concluded that small production rates would meet all expenses. In terms it was also stated that this estimation was more than met to meet the required production, and expense issue. Development which was under taken on the mine would end up increasing the ore reserves to keep the mill running at 550 tonnes per day. More so the company came to realization as it wanted to keep its milling facility up and running by maintaining a large tonnage of ore then only keeping to production. There was also a change in mining operation during this time period as the company had eliminated shrinkage stope methods due to dilution problems it had. Some more statements in relation to eliminating shrinkage stoping had also stated that this method became replace by timbering the poor walls, and developing stull stopes, and square set stopes. As these methods become place the company had yet again planned to enlarge these stopes. Much of the changes were made in order to develop three vein networks known as the old North and South Systems with what is called the incline vein system. It was strongly determined that the latter was discovered on the 1,250-foot level in 1928, and became opened up on four new levels in 1929, and 1,470 feet of ore had been developed. Not only did this maintain production and reserves but the grade of this ore was also reported to have been well above average in the mine it self. More statements had stated that these ore-bodies , with a dip of 45 degrees sometimes, were known to have a weak hanging wall, and could not be successfully mined by the Shrinkage stope methods.
Some more openings were also being made on the North or No. 1 vein which showed excellent ore results on the 1,375, 1,500, and 1,750-foot levels. These were rather sections of the old Middle Claim Ore-Shoot, which were very well faulted. In addition to this, it was also determined that this maintained production as it could easily be develop and mined at the time.
It was also determined in 1929, that a new ore-shoot was discovered on the east claim on what is known as the 700-foot level of the North Vein System. For the most part this ore-body was developed for a length of 600 feet to the major fault structure, where the ore-body became faulted south for 60 feet. Prior to this it was also stated that this ore-body was continued onward for a distance of 300 feet from this fault where the ore was of standard grade. The same ore-body is also known to occur on the 500-foot level where it had also been developed for a length of 600 feet on the No. 2, 101 vein, and 200 feet on No. 2,101 vein. This vein was rather known to have produce the highest grade of ore then any vein developed to date. Two diamond drill holes which were put down had also intersected the extension of these veins to the 2,500, and 2,900 foot horizon. Much of the structures and values from this drilling program were reported to have been more then satisfactory.
Major development had also continued onward on four ore producing level within the No. 2 or South vein systems. It was at this time when the No. 2001 ore-body to the east of the shaft on the 2,000-foot level became developed for 500 feet. Other development was also focus on the No. 2001 West Ore-body that was developed on the same level for a distance of 100 feet on the sill, and lengthened to 125 feet in the stope. The last ore-body known as the No. 1,775 East and West Ore-body was also developed on the 1,750-foot level to the east of the shaft, and directly above the No. 2,005 stope. It was also determined that the area below these ore-bodies was entirely in virgin ground which held significant results in finding extensions.
it was also on the 500-foot level when an important ore-shoot known as the No. 512 was found 900 feet east of the No. 3 Shaft, which was 150 feet long by 12 feet wide. For the most part this ore-body was determined to have been lying directly underneath the No. 2 Shaft in 1929. This discovery along with the newly discovered further east from the workings had rather given a lot of importance to maintain production, and ore-reserves. Besides the No. 512 ore-body the company had shortly after discovered the No. 502 ore-body that was directly west of the old No. 404 stope. At the time, it was also stated that this development was rapidly being push towards conducting further explorations on the No. 502 stope. Planning at the time was also focus on the future development of the continuation of opening the No. 1 vein system on the east claim, and on the two lower levels.that have an interference with the Sylvanite corner, which occurred on the upper levels of this vein, and was not expect to continue down to the lower levels. For the most part, this vein was strongly far south of the Sylvanite corner, but still had been on that property for the company to miss it from the underground explorations. In addition to adapting new stoping procedures the company could now work out some of the old stope sections on the No. 1 and 2 veins. Most of this will be done in preparation to sinking the shaft further and establishing four new mining levels. With such discoveries made it was soon stated that the ore-reserves within the Wright-Hargreaves Mine were once again relived. Reserves of broken and unbroken ore had also rather dramitically increased by 300% from the indicated reserves on May, 1929. If development continues to be satisfactory like it has been in the past few months this will rather give the mine several more years of operating. As exploratory work had continued this had rather increase ore reserves but the mine still face some its own problem as the Wright-Hargreaves Mine ore was difficult to grade. At this point in time the company had also calculated an ore reserve of 418,877 tonnes to maintain its production and milling operations. Lateral development from the mine was also extensive as 61,459.25 feet of drifting, 12,300.9 feet of crosscutting, and 28,062 feet of diamond drilling was done.
Production from the mine during this time period had amounted to 188,238 tonnes of ore, which produce a bullion recovery of $1,741,872, and average $9.25 per ton. Additions were also added to the milling facility which included three new agitators, and a low pressure compressor. By 1929, the mine had treated 1,221,055 tonnes of ore, which produce a bullion recovery of 12,879,076 tonnes, with an average grading of $10.55 per ton.
1930 - Wright Hargreaves Mines, Ltd. - 117,454.90 ounces of gold (Au), and 13,090 ounces of Silver (Ag)
Within 1930, the mine was well off when the company had obtained satisfactory results from development, and 421,000 tonnes of ore was developed. From this, the company had deducted 220,430 tonnes in which became milled, and over 200,000 tonnes was added to the ore-reserves. Drifting within the twelve month period had amounted to 17,837 feet, in which 8,429 feet was entirely done in ore. Some of the most important work done in 1930, was focus on the remarkable presistence of ore-shoots of the ore-shoot on the 2,250, and 2,250 foot levels. This also resulted in opening up ore on the 1,875, and 2,125 foot levels by 1,100 feet of lateral work each. Even more ore was found on the upper workings which had continued downwards from the 200 foot level. Much of the South Vein on the lower levels had also improved during this year as the company had intersected higher then normal values. Most of this was cause due to the fact that the company was able to maintain the ore-bodies from dilution issues on the hanging walls, and a more supervised sampling program was undertaken. For the most part much of the upper workings had no fill in which the company demonstrated the open stull stoping method. Further so the company had rather used the horizontal and rill cut and fill stopes which gave off excelent results on the lower levels. As development continued it was also determined the the No. 3 shaft was extended from the 2,100 foot level to a depth of 2,400 feet.Most of this sinking phase was done by raising 150 feet, and then sinking 171 feet. Prior to this only a small amount of development had occurred on the newly cut, and stationed 2,400 foot level at the time. It had rather resulted in confirming the continuity of the North and South Vein Systems of the Wright-Hargreaves Mine. By this time the company had also planned to continue the sinking phase of the No. 3 shaft to a depth of 3,000 feet by 1931. With this plan set the company had also planned to develop four new levels with the continuation of development on the 2,400-foot level. Lateral development during that year had amounted to 79,296.75 feet of drifting, 18,747.1 feet of crosscutting, 3,064 feet of raising, and 48,946.5 feet of diamond drilling. Ore reserves on hand during this time period had resulted in 619,605 tonnes of ore with an average of $11.83 per ton, which had a value of $7,334,604.
For the most part, the on-site mill had also received the much needed equipment to operate at full capacity. Much of the newly installed equipment had also improved the recovery significantly and was the most up to date technology in metallurgical equipment within the district. Milling during this time period had treated a total of 220,430 tonnes of ore was treated at an average grade of $12.20, which produce a gross value of $2,687,828. It was also within this time period that total of 254,511 tonnes was also lost within the tailing from the discarded ore. As the mill had operated it was also reported that this mill would 602.4 tonnes of ore on a daily basis
1931- Wright-Hargreaves Mines, Limited -140,520.42 ounces of gold Au, and 17,759 ounces of silver Ag.
During 1931, the company was well off with this historical project when the sinking of the No. 3 Shaft was continued to a depth of 3,125 feet below the surface. Prior to this it was also determined that the mine had increase in operation and the ore-body was carried down to even greater depths. With this taking place the Wright-Hargreaves Mines, Limited had decided to sinking another shaft known as the Central Shaft. Other statements from the company had reported that the No. 1 Shaft was now the main service shaft, and had only one cage, which would not be able to handle operations at a large scale. It was also within this time period when preliminary work was started on the No. 3 Shaft shortly after the sinking campaign was finish. With shaft sinking continuing there was also several buildings which were in the way and had to be moved before leveling was started for the Central Shaft Zone. By this time the company was well off with this project when the Central Shaft had reach its own depth of 300.5 feet below the surface.
As sinking had continued onward the company and its workforce was well off with this production. It was the development which became extremely satisfactory, and 400,000 tonnes of was officially developed. Deductions were also made when the mill during that time period had treated 266,353 tonnes of ore in which 134,000 tonnes became stockpiled. Drifting during this time period was also extensive as 16,017 feet was done, in which 7,958 feet was in good ore. Development which was undertaken had became extremely important due to the fact that the company’s work force was working on cutting the C ore-body. It was also determined that this was apart of the South Vein System, and been discovered south of the old South Vein. Most of this new discovery was reported to have been first discovered while sinking the No. 3 Shaft below the 2,700 foot horizon. As sinking had progress it was also reported that the vein at about 2,800 feet had dip away from the shaft to the south. After conducting further exploratory work it was then once again pick up, and had been open up on all four of the lowest levels. Further ore-cutting was anticipated as another important ore-body known as the North Vein Series had been developed on the newly establish levels with the exception of the 2,700-foot level. It was on this level where the company’s workforce had determined that the ore-body was displace by a strike fault. A small amount of ore was developed on the upper levels as the company continued to find ore between the 400 and 1,375-foot levels. Ore from the Wright-Hargreaves Mine was also developed by 2,539 lineal feet of development between the 1,500 and 2,250-foot levels. By this time the company, and its workforce had also developed ore on the four lower levels by 1,110.5 feet that was done on the 2,400-foot level. Another 547.5 feet was also developed on what became known as the 2,550-foot level, and 438.5 feet was developed on the 2,700-foot level, while 411 feet was conducted on the 2,850-foot level. Mine development during 1931, had amounted to 93,313 feet of drifting, 29,336 feet of crosscutting, 4,992 feet of raising, and 60,915 feet of diamond drilling. Improvements in prospecting along with exploratory work had soon outlined a large tonnage of ore within the No. 3 Shaft, which made it necessary to add new skips to the loading pockets. In order to this in a safe way it was determined that a new steel head gear, and hoisting system was need to operate. It was also determined that the new steel head gear was erected during the construction of the coarse crushing plant. For the most part this had rather formed a integral part which include a 400 ton ore bin ahead of the crushers
Milling operations had also continued operating at a steady base which ended up treating a total of 266,352 tonnes of ore. By this time the on-site mill had rather obtained a gross value of $3,174,532.45 in bullion recovered. There was also a significant amount of ore that became lost in tailing which average $214,696.12 from this production. Ore reserves that were on hand during this time period had also been calculated at 753,510 tonnes with an average grade of $11.65 per ton, and had valued $8,776,551. With good ore indications, it was also stated that the mill was brought up to capacity of 700 tonnes of ore per day. A small amount of minor changes had also become added, and a new crusher plant was fully installed, which resulted in an increase in mill capacity to 800 tonnes of ore per day. Much of the plans within the earlier part of 1931, had made company officials decide on replacing the coarse crushing plant. Construction of the new coarse crushing plant was off on a slow start as it was being built around the old plant without causing interferences towards production. By this time, it was also stated that this construction phase was successfully carried out, and the new plant was in operation by November, 10, 1931. Some more improvements were made when the company had constructed a new dry house, and office that was put into operating order on December, 1, 1931.
1932 – Wright-Hargreaves Mines, Limited -171,299.25 ounces of gold Au, and 25,948 ounces of silver Ag
It was much of the development during 1932, that had greatly been focus on developing the North Vein Series on the 2,850, and 3,000-foot levels. Development which was undertaken on these levels had opened up the vein for 1,500 feet on both, and it was also determined that the vein continued onward at both ends. As development had taken place the company’s workforce would also taken some samples which average $20 per ton throughout the whole lengths. Some development work on the 2,400 and 2,550-foot levels had also become quite satisfactory for production stages. No additional work was done on the 2,700-foot level as it had conceded a roll in the vein due to a major fault strike on this horizon. By this time the company had also opened up 523 feet of ore between the 400, and 1,375-foot levels. An additional 685 feet of ore was also opened up between the 1,500, and 2,125-foot levels. Even more development had taken place when ore was being extracted from the five lower levels by 6,811 feet of lateral work. Prior to this it was reported that 2,329 feet was done on the 2,850-foot level, and 1,606 feet was completed on the 3,000-foot level. Most of the newly developed lower levels were also reported to have been on virgin ground which need further exploratory work. With the mine continuing to expand in resources the company had roughly developed 493,954 tonnes of ore, which had an average grade of $16.00 per ton. Deductions during this time period of operating had rather deducted 295,525, which 198,529 was stockpiled, and added to the reserves. Ore reserve within the Wright-Hargreaves Mine became rapidly increased as it now totalled 951,939 tonnes with an average grade of $13.54, and valued $12,888,042. Lateral development was also extensive when 111,821 feet of drifting, 37,051 feet of crosscutting, 6,647 feet of raising, and 78,654 feet of diamond drilling was done.
Extensive shaft sinking had also taken place as the No. 4 Shaft or Central Shaft became deepened to 3,710 feet below the surface. Further statements were planning to have this shaft fully finish by Februart, and place into operation by the summer months of 1932. Shaft sinking would not stop here as the No. 3 shaft had also underwent further expansions as it became deepened to 3,889 feet below the surface.
The on-site mill during this time period had rather treated a total of 295,525 tonnes of ore with an average grade of $12.85, and valued at $3,796,294.80 in bullion. To date the mill had process a total of 2,003,362 tonnes of ore with an average grade of $12.01 per ton, which produce a gross value of $24,051,977. It was also within this time period that the mill was treating a total of 800 tonnes of ore without any issue rising from this extraction. By this time the company had also confirmed that the change in its flow sheet had gradually been beneficial towards production. Other plans by the company were also aimed at increasing the mill capacity from 800 tonnes to 1,000 tonnes in order to achieve higher production rates.
1933 - Wright-Hargreaves Mines, Ltd. - 177,189.76 ounces of gold (Au), and 27,372 ounces of silver (Ag)
It was during the 8-month period when shaft sinking had continued which resulted in deepening the No. 3 shaft to 4,089 feet, and the No. 4 Shaft to 4,000 feet below the surface. Much of the work during this time period had also been confined to sinking both shaft in order to cut new stations for developing the six new levels. This also resulted in a huge amount of work when connections were being made and ore pockets had been establishing for the skips. Prior to this a small amount of drifting had also been done on the newly cut levels, and the shaft was near completions by the end of 1933. With the mine continuing to expand it was also determined that 239,563 tonnes of ore were developed, and had an average grade of $14.47 per ton. For the most part, deductions during this time period had amounted to 193,441 tonnes of ore, which 46,122 tonnes was added to the reserves. Exploratory work was also underway as the company had diamond drilled the six new levels in locating extensions to the North Vein Series. Prior to this it was determined that the extension was intersected on five out of the six levels at the Wright-Hargreaves Mine. It was at this time that diamond drilling had indicated that the north vein continued down to the 3,900-foot level, which was the lowest level at the time. Some more difficulty had come upon the company when strike fault had displaced the North Vein for 100 feet vertically on the 3,750-foot level. Ore grades which were confirmed In the intersections, and during drifting had also showed improvements in grade. As sinking had continued it was determined that the North Vein was intersected just above the 4,000-foot level in the No. 4 Shaft. Below this point it was stated that this section had two branches of the vein that had occurred. There was 536 feet of ore developed between the 550, and the 1,125-foot levels. Another 1,439 feet was developed between the 1,500, and 2,000-foot levels. By this time the company had also provided development ore by drifting 1,222 feet between the 2,125 and 2,850-foot levels, and 524 feet was done between the 3,150, and 3,900-foot levels. All lateral development completed had amounted to 119,464 feet of drifting, 42,492 feet of crosscutting, 7,987 feet of raising, and 87,805 feet of diamond drilling. Ore reserve calculations within this time period of operating had amount to 998,061 tonnes averaging $13.75 per ton, and had valued at $13,726,809. It was also during this time period when the company had wanted to complete all the necessary exploration, development, and mining above the 1,200-foot levels. Most of this was being planned due to the fact that the company had not wanted to keep several levels open for production. At the same time, other plans were being made to also explore, and develop the lower levels of the Wright-Hargreaves Mine. More so the whole entire shaft sinking phase along with underground development work, and extensions to mill and equipment became completed after 2 years of planning.
Ore which was milled in 1933, had amounted to 193,441 tonnes of ore with an average grade of $13.56 per ton. In total gross value, it was reported that the Wright-Hargreaves Mine had produce a bullion of $2,623,455.69. For the most part, it was also within 1933, when the company had made replacements by changing the old flow sheet with the new one. In order to accomplish this it had entitled close planning so that operations would not be curtailed along with production. It was also by May, 1933, when the new Flow Sheet was put in and had produce satisfactory results. Most of this was underway as it became necessary to replace this before the company had reconstructed the mill building. Prior to this it was also stated that the new steel mill was completed, and the enlargement was 65% constructed. With these changes made it also became reported that the mill was some what effected in regards to production, and ore extractions. For the most part, it was also stated that better ore grading the came from this mine project had counterbalance this issue.
1934 –Wright-Hargreaves Mines, Limited -218,203.16 ounces of gold (Au), and 39,962 ounces of silver (Ag)
A huge amount of development ore that totalled 517,884 tonnes was developed, and had an average grade of 0.60 ounces of Au per ton. For the most part it was stated that a large quantity of this ore was considered as low grade ore but had been added to the reserves with increasing gold prices. Deduction which were taking for milling had amounted 330,741 tonnes of ore, and a total of 187,143 tonnes was added to the reserves. Diamond drilling which was undertaken had rather intersected the north vein at the 4,500-foot horizon. Much of the core that was taken from this intersection had rather showed unusual geological structures, and mineralization. Some more preparations were also underway as the company wanted to prepare the new interior shaft for developing the mine below the present bottom. In order to complete this the company would need to develop the necessary hoisting stations, and ore and waste passes to connect with the No. 3 Shaft, and the upper portion of the shaft above the 3,900-foot level. Ore reserves within the Wright-Hargreaves Mine was increased significantly, and amounted to 1,185,204 tonnes of ore, in which had an average grade of 0.64 ounces of Au per ton, and valued $15,643,197. A total of 136,626 feet of drifting, 48,110 feet of crosscutting, 9,178 feet of raising, and 104,391 feet of diamond drilling was completed.
By this time, the mill altercations were also fully completed, and had obtained the full benefits of the various changes on the per-cent of extraction obtained. For the most part, it was also stated that the pilot mill had indicated a possible extraction of 96.2%, which had become better from May, 1934. Other additions to the mill had included complete sprinkler system within the mill, and shops. In addition to this, it was strongly stated that the fine grinding had produce more base metals into the bullion which carried higher-gold values as a by product. Some other problems had also occurred as the it was hard to work with, and expensive to reduce satisfactory, and the bullion shipped is not easy to check with the Mint. With this problem escalating the company had rather introduce a new refining process which would eliminate this trouble. The on-site mill during this time period of operating had treated a total of 330,741 tonnes of ore grading 0.64 ounces per ton, and valued at $4,525,149.92. Production from 1921-34 had amounted to 2,572,544 tonnes of ore, with an average grade of $12.34 per ton, and valued at $31,200,583.
1935 – Wright-Hargreaves Mines Ltd. - 213,471.380 ounces of gold (Au) and 33,556 ounces of silver (Ag)
Most of the upper working during 1935 had been completely mined out in order to decrease costs significantly. All the work during 1935, was mainly being focus on developing the lower levels, and better ventilation was now achieved. It was also during this time period when the company had encounter a large tonnage of low grade ore on these levels. For the most part it was also stated that the Wright-Hargreaves Mine had a total of 28 producing levels which were far from being abandoned. By this time the company's development program was being aimed to the easterly, and westerly portions of the property. Other statements had stated that a considerable amount of ore was scattered in places but was considered to have been much lower in grade. Prior to this it was also reported that a large tonnage of development ore was taken out in which had amounted to 400,649 tonnes. A total of 350,196 tonnes was milled from this, and the remaining 59,453 tonnes was added to the reserves. Further preparations to continue the interior shaft in order to access the mine below the 3,900-foot level was completed. As the interior shaft was place under development it was also stated that 535 feet of work was done, and another 290 feet was done above the 3,900-foot level, and 245 feet below it. For the present time being it was reported that the depth of this shaft was now reaching 4,300 feet below the surface. Lateral development within that year had amounted to 157,109 feet of drifting, 52,002 feet of crosscutting, 10,476 feet of raising, and 121,192 feet of diamond drilling. Ore reserves during this time period of operating had now indicated
Milling operations had also continued onward as the mill treated 350,196 tonnes of ore, with an average grade of 0.62 ounces per ton, and valued at $4,524,193.19. At the time, it was also stated that a better pre-cent of production was taken then that indicated by the pilot mill, which was indicated at 97.04%. The trouble that was encounter with the base metals had also been overcome by installing the refining unit.
1936 -Wright-Hargreaves Mines, Ltd. -216,210.355 ounces of Gold (Au), and 34,830 ounces of Silver (Ag)
Work in 1936, was mainly focus on extracting all the ore-reserves from the upper levels as more ore became discovered. Most of these levels had continued onward as new ore sections had been opened up to give the upper levels a large mine life. In addition to this, the company at the time had also developed 495,586 tonnes of new ore, and after deductions 387,464 tonnes milled, the remaining 108,122 tonnes was added to the ore-reserves.
Development of the Interior No. 5 Shaft was now collared on the 3,600-foot level, and was sunk further 1,255 feet during 1936, which made the bottom have a depth of 5,400 feet. In general, this would additionally allow the company to now develop the nine producing levels, which the lowest will be the 5,250-foot horizon. A huge amount of development would end up occurring as stations were now completed, and pumping chamber and sump was now constructed and equipped at the 5,100-foot level. This had also included the development of ore and waste pocket which were not yet completed to push development on the new set of levels. Other statements had confirmed the existence of the North, and South Vein which were cut on the 4,500-foot level. For the most part, the vein structure within these levels had remained the same as those develop in the upper levels. Further development would progress within the year of 1937, as the ore and waste passes would be officially completed. Lateral development during 1936 had amounted to 179,975 feet of drifting, 57,383 feet of crosscutting, 14,043 feet of raising, and 138,714 feet of diamond drilling. The total development footage which was completed to date in regards to drifting, shaft sinking, crosscutting, and raising had amounted to 263,872 feet. Ore reserves within the Wright-Hargreaves Mine had also increased to 1,353,779 tonnes, with an average grade of 0.56 ounces gold per ton, and valued $26,656,381.
Milling during this time period was also extensive when it had treated 387,463 tonnes of ore at a daily production rate of 1,058.64 tonnes. It was also reported that the grade which was produce during that time period had average 0.56 ounces of gold per ton, and produce a bullion recovery value of $4,635,003.11. Total production from 1922 to 1936 had amounted to 3,265,204 tonnes, with an average grade of 0.56 ounces of gold per ton, and had a value of $51,033,506. It was also within 1936, when the on-site mill had operated at 96.55% of its full capacity that year. By this time the company had also removed the old tailing stockpile as it was now being used as field for the first time. Most of this was done by the Wright-Hargreaves Athlete Association which was entirely made up of employees. The sports which were made use on this field had included baseball, softball, and football. In regards to this, there were several trophies which became obtained by the clubs playing under the auspices of the Athlete association.
1937 – Wright-Hargreaves Mines, Ltd. 220,100 ounces of gold (Au), and 34,653 ounces of silver (Ag)
Some more change became made during this time period as the Wright-Hargreaves Mines, Ltd. Had staked four claims totalling 203 acres in Morrisette Township. Most of these were being used as sand pit prier to staking these claims. It was also within 1937, when a total of 20,000 tonnes of sand was taken from these pit.
Further so the company would also acquire the surface rights on two fractions in Teck Township, for slime disposal. Prior to this, the company had now owned the two claims in Teck Township, and eight claims in Lebel Township of the Timiskaming District for the disposal of slime.
Another option was made on a group of 16 claims in Hearst Township, Larder Lake Area, within the District of Timiskaming. By this time the company had also employed 7 men for approximately 4 months in 1937. Most of this was then followed by road building, 1,397 feet of trenching, and the property was also surveyed. It was also within 1937, when the company had made a contract for 2,519 feet of diamond drilling.
It was also during this time period of operating when the on-site mill had continued to treat the gold bearing ore. Milling during this time period of operating had been done at a daily average of 1,200 tonnes per a day. A total of 429,120 dry tonnes of ore was treated, in which had recovered 220,100 ounces of fine gold, and 34,653 ounces of silver. In total, this had rather produce a market bullion of $7,714,485.82. Prior to milling the average grade of the ore was also stated to have been at 0.534 ounces of gold per ton, or $18,695 per ton. Total production from this point had totalled 3,694.324 tonnes of ore, with a value of $15.99 per ton, and had a gross value of $59,056,086. Milling which was done in 1937, was operating at a full capacity of 96.55%, and further work was required below the horizon of any mining level. So far to date it was determined that the horizon below the 5,550 foot level had a considerable amount of high0-grade ore.
Within 1937, diamond drilling on the Wright-Hargreaves Property had amount to 26,774 feet from underground, and 464 feet from the surface. Most of the lateral work that was done from underground had consisted of 4,986 feet of crosscutting, and 22,720 feet of drifting, and some 584 feet of raising was done. Sink of the No. 5 Internal Winze Shaft had also continued onward when it was now reaching a depth of 5,550 feet below the surface. The total lateral development to date had consisted of 205,076 feet of drifting, 12,471 feet of shaft sinking, 61,882 feet of crosscutting, and 101,370 feet of diamond drilling. Ore reserves were also increasing with development as the mine now had an indicated reserve of 1,455,609 tonnes, with an average grade of 0.53 ounces per tonne, and valued at $27,197,275. Most development during 1937, was mainly confined to level above the 3,900-foot level, and very little work was done below it.
1938 – Wright-Hargreaves Mines, Ltd.- 225.496 ounces of gold (Au), and 38,457 ounces of silver (Ag)
The mine and mill had rather continued to operate through out 1938, while the mill had ran at an average grade of 1,191 tonnes per day. Employment during that time period of operating was also extensive which had a workforce of 1,055 employees. It was during this time period of operating when the Internal No. 5 Shaft was continued on further to a depth of 6,404 feet below the surface. It was also during this time period when several new levels became cut, and stationed at 5,850, and 6,150 foot sections. Other stations during this time period were also cut on the mines 5,700, 6,000, and 6,300-foot levels. Lateral development which was under taken had amounted to 16,689 feet of drifting, 6,176 feet of crosscutting, 3,946 feet of raising, and 2,417 feet of boxholes were driven. Diamond drilling during this time period had amounted to 216 holes, totalling 24,520 feet in length from underground. There was also a pumping station and sump that made on the 6,150-foot level. Drifting was also done on several levels between the 4,000 and 5,000-foot levels, which resulted in very satisfactory ore disclosures. One of the levels which was extremely profitable became known as the 4,800-foot level, which had developed major lengths of high-grade ore without any change of geological structure or formation. Even far more development was confined to a new vein which became determined as the No. 8 vein, was located to the north of the present workings. By this time the vein had rather became opened up on three deep levels that commence from the 4,300-foot level, and had indicated major possibilities. During 1938, the company had also installed a 60,000 cubic feet per minute fan at the No. 5 Internal shaft on the 3,000-foot level to assure an adequate supply of fresh air for the lower levels. The much-needed ventilation through out the mine was rather largely improved to provide better working conditions. Ore Reserves within 1938, had amounted to 1,470,772 tonnes, with an average grade of 0.53 ounces of gold per ton, and have valued $27,327,522. The total development footage to date had amounted to 223,298 feet of drifting, 13,475 feet of shaft sinking, 66,632 feet of crosscutting, 18,920 feet of raising, and 186,365 feet of diamond drilling.
Milling operations which were undertaken during that year had treated 437,130 tonnes of ore, from which 225,496 ounces of gold, and 38,457 ounces of silver was recovered. Prior to this the average grade of the ore that had came with processing had amount to 0.53 ounces of gold per ton. By the end of 1938, the average daily tonnage during that time period was raised to 1,197 tonnes per day. For the most part extraction was only slightly lower by 96.02 of the capable running time. From 1922 to 1938, the on-site mill had treated 4,131,454 tonnes of ore, which produce a gross value of $67,317,938 at an average grade of $16,29
1939- Wright-Hargreaves Mines, Ltd - 221,738 ounces of Gold (Au), and 41,712 ounces of Silver (Ag)
For the most part, 1939 was rather a slow year with minor down falls as the development levels on the No. 5 Internal Shaft became handicapped. It was during this time period of operating when extensive development was progressing towards establishing raise ventilation openings. As this development had commenced it became rather completed by the end of 1939, which would allow development to take place on the lower winze levels. Even the hoisting capacity on the No. 5 Internal Shaft was increase to about 25%, and a new double deck man-cage was being installed within a compartment to access these levels. Most of this development was aimed towards completing it to speed up development on the newly establish levels. As the working continued to get deeper it was soon noted that an extra 80,000 cubic foot fan was added on the surface along with the 60,000-cubic foot fan already installed at 3,900-foot level. Much of the newly installed fan had operated through the old No. 1 Shaft operation which was now being used for ventilation purposes.
Some more changes had also became made to the No. 4 Shaft, when a double deck with double the capacity was installed for lowering, and hoisting. Diamond drilling that was done had amounted to 261 holes, totalling 41,523 feet from underground. Prior to this it was also reported that lateral work had consisted of 15,222 feet of drifting, 5,428 feet of crosscutting, and 4,221 feet of raising. The total development footage for that year was now 238,010 feet of drifting, 13,475 feet of shaft sinking, 73,597 feet of crosscutting, and 223,065 feet of diamond drilling. Ore reserves within the Wright-Hargreaves Mine had once again increase and amounted to 1,516,961 tonnes, with an average grade of 0.53 ounces per ton, which valued at $27,920,370.
Milling which was done in 1939, had amounted to 436,250 tonnes of dry ore which were treated in the mill, and the recovery amounted to 221,738 ounces of gold, and 41,712 ounces of silver. From all production that year it was rather marketed that the bullion value of the gold and silver totalled $7,828,494.36. The average grade of the ore which had went to the mill during 1939, had been 0.52 ounces of gold per ton or $18,588 per ton. Further so the mill during that year had also operated at 1,195 tonnes of per day, and had a full operating capacity of 96.54%. Some additions to the milling equipment also became added when a 20 foot Dorr Thickener became installed to take care of the concentrate of the high-grade ore from the flotation machines. From 1922 to 1939, the on-site mill had rather treated 4,567,704 tonnes of ore, with an average of 0.53 ounces per tonne, and valued at $75,426,899.
1940 - Wright Hargreaves Mine, Ltd. - 226,335 ounces of gold (Au), and 44,710 ounces of Silver (Ag)
The main property of the Wright-Hargreaves Mine had consisted of four claims, with approximately 155 acres, in Teck Township, Timiskaming District. Prior to this the company had also stake four other claims containing 203 acres in Morrisette Township for the purpose of using sand as back fill, Two other claims in Teck Township, and eight claims in Lebel Township were also used for slime disposal. Mining and milling operations at the Wright-Hargreaves Mine had continued to operate throughout the year of 1940. Employment within this time period of operating had totaled a workforce of 1,068 employees, in which 782 were place underground. Development at the time was not focus on any further sinking as the ore on the all upper levels were being developed. Lateral work which was completed in 1940, had amounted to 14,788 feet of drifting, 3,795 feet of crosscutting, and 2,469 feet of raising. Even further exploratory work was being completed when diamond drilling had amounted to 295 underground holes, totalling 46,217 feet. At the time it was also reported that the company had installed the new hoisting facility in the No. 5 Winze, which was further increased by adding a 16 men double deck service cage. Most of this was rather installed in the north end department which was being used for hoisting the men to the lower workings, along with material. In order to do this the company had to remove the Noberg Hoist from the surface of the No. 1 Shaft operation. It was known to have operated on a two shift bases which had relieved the 3,600-foot level winze hoist of its former duty of servicing. Further so it was rather unable to do or handle the increased ore production, and development on the lower workings. A major waste pass system was also completed in 1940 which connected between the 4,850, and 3,900-foot levels. Much of this development procedure had rather involved 800 feet of raising from level to level in order to permit the immediate filling of old stope sections. Ore reserves had also slightly decreased due to the much need upgrades to the mine, and had amounted to 1,431,464 tonnes of ore, with an average grade of 0.52 ounce per ton.
Milling during this time period was rather also step up in order to operate at full capacity, which treated 443,930 tonnes of ore. Production at the time was being achieved on a daily average of 1,213 tonnes of ore. This resulted in a gold bullion increase when 4,596.9 more ounces of gold were recovered then that in previous years. Extractions during that year had also amounted to 96.42% which was lower from that in 1939. At this point in time it was also stated that the current tailing which came from this treatment were being sent to the Lake Shore Mine, Limited. for a trial run. Most of this had also supplement laboratory tests, which shows a profit can be made by each company. Processing of these tailing would first be floated, and the concentrates from this treatment would be through the roasting plant at the Lake Shore Mine. Gold production from the Wright-Hargreaves Mine had totalled 226,335 ounces, and silver amounted to 44,710 ounces, which produce a bullion profit of $8,729,477.29, At the time it was also reported that the average grade going to the mill had been 0.53 ounces or $20,395 per tonne. From all production achieved it was reported that the on-site mill had produce $5,011,634, at an average value of $16.86 per ton, which produce $84, 480,931 from all production.
1941- Wright-Hargreaves Mine, Ltd - 222,283 ounces of gold (Au), and 19,297 ounces of silver (Ag)
In 1941, mining and milling operations at the historical Wright-Hargreaves Mine had continued onward. It was rather within this time period of operating when there were 323,364 tonnes of new ore that became developed, which had an average grade of 0.52 ounces of gold per ton. Prior to this it was also noted that it was 114,846 tonnes less than the tonnes milled, and 35,069 tonnes less than that developed in 1940. AS the mine continued to become further developed there was 8,003 feet of drifting done in which 2,101 feet was done in ore.
A minor amount of development was also started on the newly establish levels that were service by the winze in 1940. Development during 1941, was mainly being confined to taking production from the No. 2 or South Vein. Besides developing the South Vein the company had also progress with active diamond drilling which was carried out on the North Vein within several levels. Intersections by diamond drilling along with development had also indicated weakening of the North Vein Structure. Despite weakening of the vein, it was during that year when 2,077 feet of ore became developed, which had its own average grade of 0,69 ounces per ton. Some more concerns had also occurred due to the weakening of north vein on the lower levels which had shorter lengths, and was the main supply of ore. Much attention was also focus on the South Vein Structure which was extremely strong, but the ore occurrences that was so far discovered was very meagre. Even diamond drilling that was done had failed to locate good ore intersections on either structure. Diamond drilling which had been conducted ended up consisting of 282 underground holes, totalling 46,340 feet. Ore reserves within the mine were slightly decreased again as it now contained a reserve of 1,316,618 tonnes of ore, with an average grade of 0.53 ounces. Lateral development within 1941, had amounted to 7,131 feet of drifting, 2,160 feet of crosscutting, 3,230 feet of raising. From all lateral development, the total development footage to date had amounted to 265,976 feet of drifting, 80,781 feet of crosscutting, and 30,217 feet of raising. Gravel which was transported to the mine site had end up amounting to 58,282 tonnes of sand-grave. It was also at this point in time when 51,044 tonnes were dumped into the mine waste passes, and the balance became stockpiled. Ore reserves during 1941, had once again decreased to 1,316,618 tonnes, with an average grade of 0.52 ounces per ton.
The on-site mill during this time period had also treated 438,210 dry tonnes of ore, from which 222,283 ounces of gold, and 19,297 ounces of silver were recovered. Much of the mill feed during that year had average 0.52 ounces of gold, or $20,307 per ton, which also had recovery of 0.50 ounces or $19,571 per ton. Extractions that became completed within 1941, had been done at 96.37 of the full capacity handle. Further so the tailings which were produce had rather continued to be disposed of at the Lake Shore Flotation unit, and Roasting plant in 1941. For the most part, the values that became produce were mainly being consumed in the cost of production. In total gold value, the company had rather made net profit of $104,000 which could have been lost in the tailings piles. By November, 18, the mine had went under a strike action that was called by the Congress of Industrial Organization in eight of the Kirkland Lake Mines. Total production to date had amounted 5,440,844 tonnes, with an average grade of 0.52 ounces per ton, in which had a value of $93,379,703.
1942 - Wright-Hargreaves Mines, Ltd. - 162,231 ounces of gold (Au), and 34,257 ounces of Silver (Ag)
All the shafts within the Wright-Hargreaves Mine Property were to the west end on claim L. 1,829, except for the No. 2 Shaft, which is located at the west end of claim L.1830. Prior to this it was reported that no sinking was done during the operating year of 1942. The section which was serviced by the No. 5 Winze had not added any new information from diamond drilling, and development during that year. Most of this became establish on the already known occurrence from the deep development program which was undertaken. With this becoming, an issue it was also noted that an importance of co-operative effort was taken by the mining companies of Kirkland Lake. Most of this procedure is being aimed at systematically analyses, and co-ordinate the various occurrence experiences in depth development. Development which was completed from underground had showed that there had been 185,037 tonnes of new ore developed. Upon assaying of this new developed ore it became determined that the ore had an average of 0.41 ounces per ton. Following development it was reported that a total of 10,063 feet of drifting, crosscuts, and raises became accomplish, In which 2,017 feet was in ore, and 43,221 feet of diamond drilling was done. By the end of 1942, it was rather reported that a total of 327 underground holes, totalling 43,567 feet were completed. The total lateral work which was done to the end of 1942, had amounted to 5,744 feet of drifting, 1,896 feet of crosscutting, and 2,470 feet of raising. This had gave the mine a total development footage of 271,720 feet of drifting, 82,678 feet of crosscutting, and 32,867 feet of raising. Ore reserves had rather started to decrease as the mine now had 1,185,445 tonnes, with an average of 0.50 ounces per ton, and a value of $22,931,155.
Milling which was done during this time period of operating had amounted to 316,210 tonnes of ore, In which 162,231 ounces of gold, and 34,257 ounces of silver were produce. Following this treatment it was also stated that the average grade of the ore going to the mill was 0.53 ounces of gold, or $20,486 per ton. Extractions which were achieved during 1942, had mainly been done at 96.63% of the total capacity handle at the time. For the most part, it was strongly stated that the mill had operated at 866.33 tonnes of ore per day. Prior to milling it was reported that much of the tailing loss during that year had average 0.018 ounces per ton, giving an extraction of 96.63%. As the tailings became produce it was also during this time period when it had been shipped to the Lake Shore Mine for further processing. Regardless the company had rather decrease, and eliminated the use of its tailing ponds by processing them at the Lake Shore Mine Mill. From all milling that was done it became reported that the company produce 5,766,054 tonnes of ore with an average of 0.53 ounces per ton, and the total value from 1922 to 1942, was $99,857,646.
Further so the company had added a hospital medical plan which was put into effect, and covered employees and their families. Costs in doing this were also shared with the company, and its employees, while memberships were being optional to old employees. Following this new procedure the company had underwent a complete resampling of the tailings in the south arm of Kirkland Lake. This resulted in conclusive metallurgical testing which had been run, and resulted in significant assets that were tied up. One of the best contributions which were made towards war efforts by mining industry was that participation were made in utilization of idle time of machine tools in their shops. Most of this was done so that the companies could help the local government by making essential equipment.
1943 - Wright-Hargreaves Mine, Ltd. - 126,075 ounces of gold (Au), and 25,333 ounces of silver (Ag)
Ore continued to be developed during 1943, which resulted in 210,206 tonnes of development ore, with an average grade of 0.52 ounces per ton. Compared to previous years it was also noted that this was 34,924 tonnes less than the tonnage milled during the year. Most of the new ore that became developed was taken from drifting, raising, and the extensions of marginal stoping areas. A major down fall had also occurred as the company was short on the much need labors which had curtailed development. During 1943, the company was focus on continuous drifting of the available ore within the stopes, and a small amount of ore was also taken from crosscutting. This was also followed by a much detail geological study, and remapping of the vein structures within the mine project. More so it was stated that this work was aided by drilling, which continued to prove valuable from a standpoint of finding new ore, and in helping to correlate, and solve geological structures. Prior to this it was also reported that lateral work had amounted to 2,966 feet of drifting, 699 feet of crosscutting, and 850 feet of raising. With this completed the total development foot for the year had consisted of 274,086 feet of drifting, 83,377 feet of crosscutting, and 33,537 feet of raising. Ore reserves during this time period had also been slightly maintain when 1,150,521 tonnes were indicated, and had an average grade of 0.50 ounces per ton. Diamond drilling during 1943, had also amounted to 312 underground holes, totalling 28,167 feet.
By 1943, the on-site milling facility had rather treated a total of 245,130 tonnes of ore, which recovered 126,075 ounces of gold, and 25,333 ounces of silver. Most of this also had its own average ore grade of 0.53 ounces per ton, and extractions that year had amount to 96.93%. From all production achieved the company was able to make a gross value recovery of $5,040,980.12. As the mill continued to operate it was also reported that the total tailing loss for 1943, had an average of 0.016 ounces per ton. For the most part, the extraction improvement was known to have been obtained from a much lower tonnage mill, which had allowed for a longer time period of agitation. Further so it was also during that year that the treatment of the sulphide contents of current mill tailings in the Lake Shore Roasting Plant had continued. All production from 1922 to 1943, had rather now treated a total of 6,011,184 tonnes of ore, with an average grade of 0.53 ounces per ton, which valued at $104,898,626.
Preparations during 1943, had also been made in regards to starting up Logging, and Saw-Milling Operations. It was determined that the Wright-Hargreaves Mine had acquired these operations from Timber Limited. In Kilmer, and Hobson Townships. At the time it was rather sufficient enough for the company to make this acquisition as it provided the much needed timber required for mining operations in 1944. It was rather due to war time conditions that had place a dramatic effect on labor shortage which decrease logging, and milling work within the district. Employment during this time period of operating had amounted to a total workforce of 499 men who became employed by R. L. Healy.
1944 -Wright-Hargreaves Mines, Ltd. - 96,475 ounces of gold (Au), and 18,366 ounces of silver (Ag)
In 1944, the company had still face labor shortage issue due to the outbreak of the war. By this time it was rather working on keeping its workers on stope development, and timbering, as underground development was curtailed. Much of the percentage in drifting was rather high as the company had confined its work toward developing favorable, and partially developed areas. Lateral work which was completed that year had amounted to 3,581 feet of drifting, crosscuts, and raises, and 22,834 feet of diamond drilling. A total of 2,427 feet of drifting was accomplish that year, in which 1,567 feet was ore footage, which had an average grade of 0.54 ounces, or $21,14 per ton. In addition to this, diamond drilling which was done was greatly reduce, and only short holes were driven to test the projection of structures. With the mine continuing to expand it was rather during this time period that detailed mapping, and the study of the South Vein was completed with no new discoveries. Ore reserves at the historical Wright-Hargreaves Mine had slightly continued to decrease as it now had a proven reserve of 1,060,835 tonnes, with an average grade of 0.49 ounces per ton. Lateral development on the levels was focus on expanding the 400, 1,000, 1,375, 1,500, 1,625, 2,250, 2,400, 2,550, 2,700, 3,150, 3,300, 3,450, 3,900, 4,050, 4,200, 4,650, 4,800, and 5,100-foot levels. Diamond drilling within this time period had amounted to 20 underground holes, totalling 6,020 feet.
Milling operations at the Wright-Hargreaves Mine had continued onward when the mill treated 196,000 tonnes of ore, from which recovered 96,475 ounces of gold, and 18,366 ounces of silver. It was at this time when the average grade of the ore milled had been at 0.50 ounces per ton of ore, and had an extraction of 97.06%. For the most part, operating conditions became more difficult to maintain due to the continuation of labor shortages. Much of this had rather caused reductions in the tonnage of ore broken, and treated. The amount of gold which was produce, and the footage of underground development, and exploration had also face a curtailment in mining. Prior to this, war time machine shop work on various mechanical units used on cargo vessels for made for the government was completed. Production from 1922 to 1944, had amounted to 6,207,784 tonnes of ore, with an average grade of 0.50 ounces per ton, and valued at $108,721,951
1945 - Wright-Hargreaves Mines, Ltd. - 81,037 ounces of gold (Au), and 14,372.63 ounces of Silver (Ag)
Milling and mining operations had continued onward during 1945, but rather a slow pace due to a shortage of workers. Prior to this labour shortage it was also reported that the company ended up having curtailment problem in regards to further developing this project. As this had occurred it was rather stated that there were no ore disclosures as development was confined to extensions of known ore-bodies. This had also included the testing of value which were disclosed by diamond drilling, and no drifting was done below the 5,100-foot level. Much of the total lateral development within that year had rather amounted to 278,182 feet of drifting, 84,449 feet of crosscutting, and 34,074 feet of raising. Diamond drilling during 1945, had consisted of 42 surfaces holes, totalling 15,533 feet, and 242 holes, totalling 21,561 feet from underground. For the most part, ore reserves within the mine had continued to decrease due to labor shortages which now amounted to 990,739 tonnes of ore, with an average grade of 0.47 ounces per ton, and had valued $17,795,053.
Much of the milling operation within this time period had rather treated 159,710 tonnes of ore, which recovered 81,037 ounces of gold, and 14,372.63 ounces of silver. With milling operations commencing it was known to have produce an average of 0.52 ounces per tonne of ore, with an extract capability of 97.25%. Due to the marketing prices of gold, and war time conditions it was rather reported that mining was extensively hard to coop with, and the labour shortage was another issue. Total production to date had amounted to 6,367, 494 tonnes, with a value of $17.58 per ton, and the gross value now amounted to $111,964,035. During 1945, the company was able to recover a bullion value of $3,152,856.63 from gold, and silver bullion. Some more changes had also occurred when the company’s milling facility was only processing a total of 437.56 tonnes a day. Employment within this mining operation had also became decreased to a workforce of 415 men who became employed by R. L. Healy, the mine manager.
1946 - Wright-Hargreaves Mines, Ltd. - 83,582 ounces of gold (Au), and 15,259.29 ounces of Silver (Ag)
Curtailment of development had continued onward as a labor shortage had cause sever down falls within the 1940s. But it was at this point in time when the workforce at the Wright-Hargreaves Mine was increased to 473 men who became employed. Ore Reserves within the mine had also became a serious factor as there was 920,000 tonnes of indicated reserves due to the restricted amount of development. Some additions to the mining equipment were made during that year in order to increase production, and to reduce mining costs. Some of the equipment that became added had included an additional mechanical mucking machine, and 6 double drum slusher hoists were put into operation. Other additions include detachable bits which were largely adapted in place of the standard drill steel for rock drills. Further so the company had also established a major experimentation on development in order to improve the type of safety dog for use on mine cages. In addition to this, it had involved several free fall drop tests of the cage in the shafts. The total amount of lateral development work during 1946, had amounted to 2,483 feet of drifting, 1,415 feet of crosscutting, and 2,280 feet of raising. Diamond drilling that was done in 1946, had amounted to 25 surface holes, totalling 15,278 feet, and 208 underground holes, totalling 18,494 feet in length. The total development foot within that time period had amounted to 280,665 feet of drifting, 85,864 feet of crosscutting, and 36,354 feet of raising.
Production within the milling facility had treated a total of 169,830 tonnes of ore in which recovered 83,582,608 ounces of gold, and 15,259.29 ounces of silver. Milling operations during this time period had a daily production rate of 465 tonnes per day. Prior to this the average grade produce from the mill had been 0.50 ounces per ton with a 0.016-ounce tailing loss. Extractions which were produce during 1946, had a capability of treating 97.25% of all the ore handled that year. For the most part the economies which were effected by the newly installed Thickener had rather met expectations then that in previous years. Some more additions were also made when the company upgrade the solution tank to a steel one as it was once wooden. Other studies were also concluded towards the mill as Frothing Conditions were a major study factor in 1946. The flotation plant, which once used reagents was discontinued, and the flow sheet became re-arrange, which resulted In saving on pumping cost.
1947 – Wright-Hargreaves Mines, Ltd. - 84,626 ounces of gold (Au), and 17,853.88 ounces of silver (Ag)
Further shortages within the mining operation had rather cause a limited amount of development to be completed. With this still being a factor it became a major down fall as it kept on providing limited large tonnages of ore from being produce. Most of 1947, was mainly focus on keeping up with the much need maintenance within the underground workings to have them ready for future mining operations. Much of the broken ore reserves within the Wright-Hargreaves Mine were increased by 4,873 tonnes to 61,959 tonnes. Even more changes from previous years were made when smaller Rock Drills became added, and replace the bigger ones to provide better economical operations. Diamond drilling within this time period had resulted in 91 underground holes, totalling 7,821 feet, and 24 surface holes, totalling 16,684 feet. Lateral work within 1947 had amounted to 1,729 feet of drifting, 1,528 feet of crosscutting, and 2,812 feet of raising.
Due to the lack of inexperienced underground labors this had rather caused further curtailment in development, and a large tonnage from being produce. In terms it was also reported that further underground machanization, and resulted in constant investigations looking towards further economies. Most of the maintenance during 1948, was focus on timbering level workings, the ventilation, and the fire control system, along with the hoisting and loading facilities, the pumping equipment and pump lines, which required constant attention and expense. Most of the waste rock for the stope fill purpose was also being hauled throughout the summer season.
During the operating period of 1947, the on-site mill had treated 181,114 tonnes of ore, which recovered 84,626 ounces of gold, and 17,853.88 ounces of silver. Ore within this time period had an average grade of 0.53 ounces per tonne, and had produce a bullion value of $3,006,771.60. It was also within this time period when the company had received an average of $0.78 per ounce of silver, and $35 per an ounce of gold.
1948 - Wright-Hargreaves Mine, Limited -85,657.002 ounces of gold (Au), and 18,354.38 ounces of silver (Ag)
Development work on the Wright-Hargreaves Mine was once again progressing when the company had sunk the No. 5 Internal Winze Shaft further. By this time it was also reported that the internal winze shaft was deepened by 73 feet to a total depth of 7,272 feet below the surface. With the mine continuing to expand it was at this point in time when stations, and shaft pockets became cut on the mines 6,600, 6,900, and 7,200-foot levels. For the most part this had rather experience some challenges as ground conditions, and rock pressure had slow this process of work down. Prior to this it was also followed by several months of change over within the winze from sinking arrangements to regular shaft hoisting operations. As the mine continued to expand it was also at this point in time when crosscuts were driven northerly on the three newly developed levels to investigate the values, and geological structure. These values were rather intersected by a deep diamond drilling program the warranted the sinking phase of the internal winze. Even more pilot drill holes had then been driven from the crosscuts on the 6,900, and 7,200-foot levels. At the time it was reported that the former had showed no values, but the latter carrying values in one hole, which was well above the mine grade needed. Most of these intersections had revealed that the core within this section had showed characteristics of quartz, and porphyry. Lateral development that was done had amounted to 1,466 feet of drifting, 1,518 feet of crosscutting, and 2,393 feet of raising. Diamond drilling within 1948, was rather known to have been done from underground, which resulted in 76 holes, totalling 7,373 feet.
The on-site mill during 1948 had continued to operate on a steady basis which end up treating a total of 181,439 tonnes of ore. From this production, the mill was able to recover a total of 85,657.002 ounces of gold, and 18,354.38 ounces of silver. During 1948, the average price of $0.74 per an ounce was received for the silver, and $35 per an ounce was received for the gold. Milling within this time period of operating was done at a daily average of 496 tonnes of ore per day. Even broken ore reserves had slightly increased by 9,224 tonnes of ore, and the total development work was less than 4%, and diamond drilling by 30%. From the commencement of operation in 1922 to the year of 1948, the mill had rather treated a total of 6,899,877 tonnes of ore. From this the company was able to obtain a gross value of $121,424,695, and the bullion produce was marketed at $115,616,560.00. Extractions which were completed during this time had ran at 97.28% of the capable running time, and a total of 0.013 ounces of gold was lost in the tailings.
1949 - Wright-Hargreaves Mines, Ltd - 85,895.78 ounces of gold (Au), and 15,960.87 ounces of silver (Ag)
Milling operations during this time period of operating had treated a total of 196,650 tonnes of ore, which recovered 85,895.78 ounces of gold, and 15,960.87 ounces of silver. The processing of this ore had rather average $0.72 which was received for the silver, and $35 per an ounce in gold. It was also within 1949, when the mill was slightly increased to a daily production rate of 538 tonnes. From this production, the company was able to receive a total gross value of $3,110.794.87. From all production since commencement of operations it was now indicated that the mine produce 7,096,527 tonnes of ore, which had a gross value of $124,535,490. Milling which was done had also ran at an average of 0.45 ounces per ton, and the tailing loss amounted to 0.013 ounces of gold per ton. There were also no changes made to the metallurgical practises besides re-building the No. B1 filter, which also included installations of a new shaft, and trunnion. Some repairs had to also be made to the tailings line, and dam within this year which were greater than previous years.
By the end of 1949, the company was well off with this production once again as improvements were made towards producing a large tonnage of ore, development, and the much-needed labour was increased. From all development, it was reported that the tonnage was greatly increased from the last few years of operating in the 1940s. Prior to this there was also 9,432 tonnes of waste rock which was hauled on the surface, and dumped into the waste passes. Even further development had escalated when sixty-two underground ventilations and fire control doors, seven permanent concrete, and one wooden, bulk heads were constructed. Some more additional equipment to the mechanization within the underground workings was added, which included a mechanical loader, and two double drum slusher hoists. Lateral work during 1949, had consisted of 2,727 feet of drifting, 1,497 feet of crosscutting, and 2,570 feet of raising. The total development footage of the mine had ended up amounting to 286,607 feet of drifting, 90,463 feet of crosscutting, and 44,129 feet of raising. Diamond drilling within 1949, had amounted to 80 underground holes, totalling 7,244 feet in total length.
1950 -Wright-Hargreaves Mines, Ltd.- 83,647.077 ounces of Gold (Au), and 16,438.220 ounces of silver (Ag)
No additional sinking was made during the 1950s as the shaft and internal winze had stayed at the same depths. Development was rather picked up once again when an increase was made that amounted to 3,218 feet of drifting, 1,332 feet of crosscutting, and 3,094 feet of raising. Most of the exploratory work of the deep levels was help up for the large part of the year as the company was awaiting the completion of the ventilation raise. Much of this had driven the raise from the 7,200-foot level for a total footage of 1,005 feet in order to make a connection on the 6,100-foot level. This connection would allow the raise to be connect with the other ventilation raise which travels down to the 6,100-foot level from the surface. Far more development would then take place when an escape compartment was made on the one side of the new raise. Prior to this development the company had also place requisite air-control outlets, which were set in concrete bulkheads with steel entry doors at the raise, and were establish on each level between the 6,150 and 7,200-foot sections. For the most part, mining operations were rather the same as last years besides an increase in ore production from levels below the 3,900-foot level by the No. 5 Internal winze shaft. As this had occurred it would also place an increase towards the waste rock from deep level development. Most of this had rather caused additional hoisting time on the hoists of the No. 3 and No. 5 Internal Winze Shaft. It was also at this point in time when the company had purchase additional mechanization underground equipment which would be used in ore production, and improvements in rock drilling techniques were made. Further so, the accident frequency rates for 1,000 man-shift for all accidents absenting an employee from work for one or more days was 0.115. Drifting which was completed on the lower levels was far more less as the ventilation raise was being completed.
Milling operations during this time period had rather slightly increased from previous years when 196,036 tonnes was treated. From this treatment process, there was a recovery of 83,647.077 ounces of gold, and 16,438.220 ounces of silver. It was also at this time when $38.50 was received for an ounce of gold due to the 10% devaluation of the Canadian dollar, and $0.80 per an ounce of silver. Prior to this the tonnage mill was pretty much the same as last year, but development was far much greater. Ore which became milled during 1950, had rather been process at 537 tonnes per day as the mine was slowly revived from the war conditions. The overall production from since the commencement of operation had rather showed that the mill treated 7,292,563 tonnes. Values which were obtained from a ton had been at $17.53, which had a gross value of $127,860,105, and the bullion produce had a value of $121,866,104.
1951 - Wright-Hargreaves Mines, Ltd. - 78.537.216 ounces of gold (Au), and 17,071.16 ounces of silver (Ag)
For the most part, development within 1951, was mainly focus on the deep levels and developing the north and north heading veins. Most of this development had taken place to the west of the main crosscut north, which was the most favourable area that was outlined by deep diamond drilling. It was also at this time when most of the area had been completely developed by lateral work. In addition, it was also stated that the ore-footage which was disclosed by development had only indicated possible ore. Further lateral development was needed in order to prove the existence of indicated ore, in which could only be proven by blocking it out by raising in several indicated sections. Some more challenges had also come with this as the greater rock pressure, the charicturistic of the ore-bodies, and host rock, and the higher cost of mining these depths became a factor. Development on the westerly portion of the mine had taken place when a raise was driven between from the 7,200 -foot level to the 7,050-foot level, and the 6,900-foot level. This had rather consisted of a total length of 382 feet that was completed during the development of this raise. Its main purposes for being developed was going to be used as ventilation raise, and for the ore and waste pass system. Diamond drilling that was performed during this time period of operating had consisted of 43 underground holes, totalling 6,989 feet. The purpose for establishing this drilling program was to assist in the development of the levels, and for exploratory purposes. At the time, the tonnage broken in stoping operations was completed on a lower scale, and had been developed at the same tonnage milled in 1951. Underground labour during this time had also prevailed, but the broken ore capacity was rather reach in order to keep up with milling operations. Prior to the following years of development, it was rather stated that a large number of workers were kept on hand to develop ore at the lower levels. Production which was achieved from the No. 5 Internal Winze shaft was rather done at a large scale along with exploratory work on these lower levels, and development. Lateral development during that year had amounted to 3,993 feet of drifting, 1,074 feet of crosscutting, and 3,211 feet of raising. From this the total development footage of the mine had amounted to 293,818 feet of drifting, 92,859 feet of crosscutting, and 50,434 feet of raising.
Production that was achieved within the milling facility had ended up totalling 183,710 dry tonnes of ore. From this it was rather reported that an average grade of 0.445 ounce per ton was recovered, and the gold recovery was 78,537.216 ounces of gold (Au), and 17,072.61 ounces of silver (Ag). Ore tonnage which was mill during that year was far more less than that of the following year, but development was up by 20%. From this diamond drilling was also significantly up from the following years by 48%, which was done. During 1951, the average received for an ounce of gold was $36.88, and silver was purchase at $0.91 per an ounce. From all production, the company was able to make a gross value of $3,003,490.06, which the mill had operated at 503 tonnes per day. Additions also became made when the company had converted the four of 5-foot diameter tube mills to two 6-foot by 8-inch diameter tube mills. Most of this would rather be used for the sized of mine-run-ore as the grinding media was completed in the latter part of January, 1951. By doing this it had also eliminated the use of steel grinding ball in the secondary grinding circuit which were a very costly to use at the time. From overall production, the milling facility had treated a total of 7,476,273 tonnes of ore, which had a value of $17.50 for a gross value of $130,863,595. Employment within the mining operation was rather at a low stand off with only 453 employees in 1951. Diamond drilling during 1951 had amounted to 117 underground holes, totalling 13,948 feet in length.
1952 - Wright-Hargreaves Mines, Ltd - 80,195.635 ounces of Gold (Au), and 14,721.87 ounces of Silver (Ag)
Development during 1952, had rather slightly decreased from previous years of operating the Wright-Hargreaves Mine. It was within this time period when the company, and its workers had completed 2,280 feet of drifting, 1,821 feet of crosscutting, and 5,455 feet of raising. From this lateral development, the total footage completed was 296,099 feet of drifting, 94,680 feet of crosscutting, and 55,889 feet of raising. Diamond drilling which was done had amounted to 146 underground holes, totalling 17,549 feet in length. Hoisting that was done had also totaled 189.770 tonnes of ore which was also milled at the on-site milling facility.
Milling within 1952, had amounted to 190,630 tonnes of ore with an average grade of 0.436 ounces per ton. From all production, the mill was able to recover 80,195,.635 ounces of gold (Au), and 14,721.87 ounces of Ag. Prior to this it was also stated that $35.70 was received for an ounce of gold (Au), and $0.87 was received per an ounce of silver. In addition to this, the tonnage that was produce at the mill was 6,000 tonnes greater than that treated in 1951. From all production, the company was able to recover a gross value of $2,957,002.96 in gold and silver bullion at a daily production rate of 520 tonnes of ore.
1953 - Wright-Hargreaves Mines, Ltd. - 82,551.115 ounces of gold (Au), and 16,440.65 ounces of silver (Ag)
Ore during 1953, was rather disclosed on the 7,050-foot level which was confined to the D vein structure above ore opened by drifting in 1952, on the 7,200-foot level. Prior to this it also became evident that the North Vein, and North Heading Vein were discovered between the 7,200, and the 6,900-foot levels. Diamond drilling from underground was followed by the completion of 36 holes, totalling 7,112 feet in length. A small shortage towards labor was still present but the mine had continued to operate at a large scale through out 1953. Some more changes had also became made when the company adapted tungsten carbide detachable bits, along with much longer rods, and lighter pusher type rock drills. From this change it was rather reported that its increase the efficiency in regards to stoping, and development work. Development was mainly confined to the No. 5 Internal Winze levels between 6,750, and 7,200 foot level. Most of the work during that time period was focus on blocking out the ore by raises, and sub-drifting had continued. Diamond drilling that was fully completed in 1953, had amounted to 123 underground holes, totalling 15,430 feet in length. Hoisting which was done had also taken 192,390 tonnes of ore that was treated at the mill during 1953. The total lateral development that was done had also consisted of 2,814 feet of drifting, 914 feet of crosscutting, and 4,920 feet of raising.
Milling operations had also continued when 191,870 tonnes of ore became treated, which had an average grade of 0.446 ounces per ton. From this production, it was rather reported that a total recovery of 82,551.115 ounces of gold, and 16,440.65 ounces of silver was recovered. At the time, it was also stated that the company had received $35.70 per an ounce of gold (Au), and $0.83 per an ounce of silver (Ag). The overall production which was milled from 1922, had now amounted to 7,858,733 tonnes of ore, which was milled at a value per ton of $17.40 for a gross value of $136,750,122. For the most part, milling operations within the operating year of 1953, had been achieved at 525 tonnes of ore per day, and a gross value of $2,929,524.41 was taken.
1954- Wright-Hargreaves Mines, Ltd- 78,785.703 ounces of gold (Au), and 14,412.38 ounces of silver (Ag).
Much of the development in 1954, was focus on new ore that was taken from the 7,050-foot level. It also became known that this production was apart of the extension of the North D vein. By this time the company, and crew of 447 men had continued to progress with exploratory work on the North, and North Heading veins. Prior to this it was also becoming further developed by drifting, and raising in preparation for stoping operations. More efficiency had improved within the drilling process of the stopes, along with breaking, and in development work of all classes, drifting and raising. Further so this was rather completed by the progress of skillful miners who had adapted to the pusher type rock drills, which had longer drill rods,and tungsten carbine bits. It was also during that time period when eight additional drill was added for further exploratory work and development procedures. During the progress it was stated that these drill had preformed the required work in providing good results. Even more equipment had also became added when another slusher hoist was now in use. Most of the development work was focus on the deep levels of the No. 5 Internal winze shaft, and had mainly been aimed at blocking out the ore by raises, drifting, and subdrifting. In order to perform at good pace, the company was also adapting the proper ventilation measures towards this operation. Development at the time was also focus on constructing an ore pass, which was driven from the 5,700-foot level to the 5,250-foot level of the No. 5 Internal Winze Shaft. Much of this development procedure was done in order to serve three levels above the 5,700-foot level of the Wright-Hargreaves Mine. Diamond drilling which was completed during that year had amount to 15 surface holes, totalling 3,073 feet, and 123 underground holes, totalling 20,273 feet. At the time, it was also reported that experience miners were scarce but other laborers were in ample supply. For the most part, this had also resulted in the lowest labour turn over in years of operating the Wright-Hargreaves Mine Site. Lateral work during the time period of 1954, had resulted in 2,408 feet of drifting, 726 feet of crosscutting, and 4,539 feet of raising. The total development footage being 301,321 feet of drifting, 96,320 feet of crosscutting, and 65,348 feet of raising.
Further milling operations were still commenced during this time period of operating the Wright-Hargreaves Mine Site. It was within this time period when the mill had process a total of 191,890 tonnes of ore, with an average of 0.426 ounces per ton. Processing of this large tonnage had produce a recovery of 78,785.703 ounces of gold (Au), and 13,412.38 ounces of silver (Ag). During 1954, the average price per an ounce of gold was marketed at $34.18, and silver had a market price of $0.83 per an ounce. The total overall production which was taken from the mine site had amounted to 8,050,663 tonnes of ore that was milled. From this milling process it was strongly reported that $17.33 per ton was obtained, which produce a gross value of $139,539,032.
1955- Wright-Hargreaves Mines, Ltd. - 79,146.418 ounces of gold (Au), and 15,033.30 ounces of Silver (Ag)
Some new changes had occurred during 1955, when the New No. 6 Internal Winze Shaft was collared to the depth of 10 at the 7,200-foot level. Plans at the time were made to make thins winze vertical with two compartments, and to sink it to a depth of 7,900 feet below the surface. It was also at this time when diamond drilling was being done at a large scale to explored the veins below the 7,200-foot level Much of this exploratory work had rather located narrow vein structures under the developed areas between the 7,200- foot level, and the 6,600-foot level, in which resulted in stoping. Diamond drilling which was completed had consisted of 20 surfaces holes, totalling 11,025 feet, and 96 underground holes, totalling 20,963 feet. Hoisting within the operating year of 1955, was also extensive when 190,540 tonnes was taken, and milled. Lateral work within 1955, had amounted to 1,274 feet of drifting, 1,491 feet of crosscutting, and 2,632 feet of raising.
Milling of the ore was slightly increase to 193,560 tonnes of dry ore, with an average of 0.424 ounces of gold per ton. From all milling that was done it was strongly reported that 79,146,418 ounces of gold (Au), and 15,033.30 ounces of silver was recovered. Pricing during this time period of operating had also amounted to $34.25 per an ounce of gold, and $0.85 per an ounce of silver. For the most part, milling during 1955, was mainly operating at a daily average of 530 tonnes of ore. From all production since the commencement of operations in 1922, the mill had treated 8,244,223 tonnes of ore with a value of $17.27 per ton. From all production, it had produce a gross value of 142,342,500.00, and the bullion produce was $135,931,630.00.
1956 - Wright-Hargreaves Mines, Ltd - 77,684.595 ounces of gold (Au), and 14,996.60 ounces of silver (Ag)
It was at this point in time when sinking of the new No. 6 internal shaft had continued onward from the surface. With sinking continuing it was reported that the winze shaft had reach a depth of 8,130 feet below the surface. Following the sinking phase there were also new stations cut at 7,350, 7,500, 7,650, 7,800, 7,950, and 8,100 feet. Following this development, the company had made agreements on February, 4, 1956, with the Kirkland Townsite Mine, which had adjoined the Wright-Hargreaves Mine on the south. Most of this agreement had provide a lease on the mine site for a total of 50 years. Further development work on the Kirkland Townsite Mine was once again continued on February, 6, 1956.
Development work had first taken place from the 3,000-foot level where it was determined that the main vein from the Wright-Hargreaves Mine had continued. Most of the vein system had rather cross a corner of Kirkland Townsite property for a distance of 112 feet. Upon examinations, it was found that the vein structure was weak, and no ore had been found. Diamond drilling that was done. Prior to this lease the company had commence diamond drilling from the 2,850, 3,000, and 3,150-foot levels. For the most part this drilling program was aimed at exploring the zone further, which also proved to be fruitless. It was rather several years ago when a mineralized structure was found by drilling the Wright-Hargreaves south claim, and to explore the westerly extension of this structure. Expectations were made that this vein had crossed into the Kirkland Townsite property some 1,200 feet south of the boundary. At the time, it was reported that two horizontal holes, were drilled from the Wright-Hargreaves 3,750, and 5,100-foot levels. From this drilling program, it was determined that the first of these holes on the 3,750-foot level had intersected five narrow quartz stringers in a zone 350 feet wide in greywacke, but only low values were obtained. The second of these holes from the 5,100-foot level had showed the mineralized zone to have narrowed to a width of 50 feet, but its structure was surprisingly stronger, and gave off better values, which was still below ore grade. Lateral work on the Wright-Hargreaves Mine had amounted to 2,382 feet of drifting, 1,361 feet of crosscutting, and 2,783 feet of raising. The total development footage within the wright-Hargreaves Mine had amounted to
Milling operations were largely decrease when the mill had treated 175,280 tonnes of ore, with an average grade of 0.460 ounces per ton. From all production, the on-site mill was strongly known for recovering 77,864.595 ounces of Gold (Au), and 14,996.60 ounces of silver (Ag). During the operating year of 1956, the average price for gold had amounted to $34.74 an ounce, while silver was at $0.90 an ounce. Production achieved from the commencement of mining had amounted 8,419,503 tonnes of ore, with an average value of $17.24 per ton, and a gross value of $145,135,532.00.
1957 - Wright-Hargreaves Mines, Ltd -103,662.611 ounces of gold (Au), and 17,750.21 ounces of silver (Ag)
It was under lease agreements with the Kirkland Townsite Gold Mines, Limited, when a drift on the 3,000-foot level was extended into the Wright-Hargreaves Mine, with some mining completed. From all development including shaft sinking but no including work done on the Kirkland Townsite least had amounted to 9,694 feet. From this development, 2,970 feet of the main level, and sublevel drifting was completed, while 1,026 feet of the total was in ore averaging 0.538 ounces of gold over a width of 5.4 feet. Most of the major development during 1957, was focus on completing the No. 6 Internal Winze Shaft, and the opening of six new levels below the 7,200-foot level. By the later part of 1957, it was reported that crosscutting on the vein structure was completed on all six levels, and drifting in ore commenced during December on the 7,950, and 8,100-foot levels. It was at this time that hoisting was required below the 7,200-foot level which had needed better ore-grade for additional hoisting and other costs. Value which were obtained in drifting on the new levels had rather exceeded this expectation to commence further development.
Stoping during 1957, was also commenced on 39 of the 51 main levels down to the 7,700-foot level. For the most part in previous years these were rather small, isolated, irregular lenses, and tail ends of ore-shoots. Mining in these sections during that time period had proven to be expensive, which frequently resulted in moderate tonnage of new ore found. It was rather noted that considerable part of ore reserves had remained within these small, scattered blocks, and this had necessitated maintenance of long sections of the main levels. Ore that was hoisted from the Wright-Hargreaves Mine had resulted in 219,922 tonnes of ore from stopes, and 16,200 from development. An increase was also made to the broken ore reserves by 950 tonnes to a total of 97,072 tons at the end of 1957. Development in available unbroken and broken reserves was reduced by 31,540 tons, after milling 236,122 ton during the 16-month period. It was rather estimated that a total of developed, and indicated ore, including that inferred below the 7,200-foot level largely from diamond drilling data, was sufficient to ensure production at an average daily operating rate of 460-tonnes for about 5 years. Ore reserves within 1957, had amounted to 517,092 tonnes of ore, with an average grade of 0.390 ounces per ton, this had also included probable ore of 460,692 tonnes.
Diamond drilling had also been continued onward in conducting exploratory work on the mineralized zone of the Kirkland Townsite Mine. Most of this exploration work was done at about 1,200 feet from the boundary of the Kirkland Townsite Property. It was reported that two long horizontal holes were driven from the 6.150-foot level, and the other on the 7,050-foot level into this zone with discouraging results.This was also followed by a recent drilling program towards the Wright-Hargreaves Mine Property from the 3,750, 5,100, 6,150, and 7,050-foot levels. Surface drilling which was done on the Kirkland Townsite property had also intersected an altercation, and mineralization with occasional gold values in the south zone. Much of this drilling program from previous years had failed to prove a major geological structure worthy of further exploring under existing conditions. Prior to this the company was well off with mining a small ore-shoot which was apart of the Subsidiary Vein on the Wright-Hargreaves South Vein System. From here the vein is commonly known to cross the corner of the Kirkland Townsite Mine property between the 2,850-foot level, and the 3,000-foot level.
During the production period of 16 months it was also stated that the mill had treated 236,122 tonnes of ore with a average grade of 0.453 ounces per ton.The total gold recovery for that period of operating 103,662.611 ounces of gold, and 17,750.21 ounces of silver.Some major changes had shortly after occurred when a mill clean up was ordered, and this would permanently shut down milling operations at the Wright-Hargreaves Mines. An additional 7,856,344 ounces of gold, and 1,075.42 ounces of silver became recover from the claen up, and the mill would cease operation on July, 2nd, 1957. The total bullion at the end of 1957, had a sales average of $3,757,415.04 from all processing that was done that year. Most of this suspension was caused due an agreement that was made between Lake Shore Mines, Ltd that would treat 500 tonnes of crushed ore per-day. Much of the average daily milling rate for that year had amounted to 484 tonnes of ore per day. with an extraction rate of 96.91%.
1958 -
The total development footage for the operating year of 1958, had been at 8,220 tonnes of ore, compared with 6,920 tonnes in 1957. Work at the time was mainly confined to the development, and exploration of ore-shoots on the six new levels of No. 6 Internal Winze Shaft below the 7,200-foot level. Prior to this there was a total of 4,542 feet of drifting done on these levels, in which 2,329 feet was done in ore averaging 0.606 ounces per ton over an average width of 5.3 feet. With the new levels developed it was during that time period when 1,197 feet of raising was done toward completing a ventilation raise between the 8,100-foot level, and the bottom of the main ventilation raise system on the 7,200-foot level. It was also during the operating year of 1958, when a new fan became installed on 6,150-foot level in order to increase the supply of fresh air. Diamond drilling that was done from underground had amounted to 79 holes, totalling 16,611 feet. From all lateral development completed there was 4,697 feet of drifting, 746 feet of crosscutting, and 1,492 feet of raising done.Work on the six new levels within 1958, had continued to develop high-grade ore below the 7,200-foot level, with an average grade of 0.452 ounces per ton. Reserves of unbroken, and broken ore were largely reduce during the year by 127,423 tonnes of ore after milling 177,285 tonnes of ore, which had excluded the Kirkland Townsite Mine. Conclusion were shortly after made that the development between the 8,200 foot level, and 8,100-foot level would add to the ore reserve tonnage in 1959. Hoisting from the underground workings during that year had amounted to 179,545 tonnes of ore that was milled, and treated at 492 tonnes per day at the Lake Shore Mill.A total of 38 out of 51 stopes were in production during the operating year of 1958, and were confined to the main levels down to7,200-foot level. Stope preparation would also commence during the operating year of 1958, and was done 4 of the 6 new levels below the 7,200-foot level. It was at this time when a considerable amount of ore was broken in small, isolated tail end of ore shoots, that were left in various parts of the mine. Development of these ore-shoots had became the main issue in regards to the grade that was recovered in the mill at the Lake Shore Mine. Broken ore reserves within the Wright-Hargreaves Mine, were reduced by 21,663 tonnes to a total of 75,609 tons at the end of that year. With development commencing there was also an additional 1,350-tonnes of ore in the Kirkland Townsite Stopes.By this time the company had not completed any development or diamond drilling at the Kirkland Townsite Mine Property in 1958. However, a small ore shoot was rather mined within a subsidiary vein of the Wright-Hargreaves Main vein, system..Examinations of the vein had continued onward as it cross the corner of the Kirkland Townsite Property between the 2,850-foot level, and the 3,000-foot level. From this ore shoot there was a total of 2,260 tonnes of ore that became blocked out, with an average grade of 0.557 ounces of gold per ton, from which 1,210.80 ounces was recovered. Ore reserves that were indicated in the Wright-Hargreaves Mine Property had rather totaled 389,699 tonnes, with an average grade of 0.452 ounces per ton. The total amount of hoisting which was done during 1958, had totaled 166,073 tonnes from stoping, and 13,472 tonnes from development ore.
Production during the operating year of 1958, was achieved at the Lake Shore Mine Property. The total tonnes of ore that was treated had amounted to 179,545 tonnes with an average grade of 0.393 ounces per ton.From all treatment the mill had commonly recovered 67,902.73 ounces of gold, and 17,693 ounces of silver. This recovery had also included an additional 1,210.80 ounces of Gold, which was recovered from 2,260 tons of ore mined from the Kirkland Townsite Mine. Most the milling that was done at the Lake Shore Mine had also been under joint agreement All production that came from the Wright-Hargreaves Mine was done at a daily rate of 491 tonnes, and the extraction recovery was 96.3%.
1959 - Wright-Hargreaves Mines, Ltd. -69,000.996 ounces of gold (Au), and 17,338 ounces of Silver (Ag)
Some major changes had occurred within 1959, when the Wright-Hargreaves Mines, Ltd. had came to agreements with the Slyvanite Gold Mines, Ltd. This agreement had entitled the two companies towards a joint venture agreement towards exploratory work that was of importance. Much of the agreement had involved the exploratory work towards a block of ground lying below the 5,500-foot level, and continued down to the 8,100-foot level. It was also at this time when the block of ground had comprised of both properties, which included the Sylvanite Mine Property, and the Wright-Hargreaves Mine Property. With agreements made most of this exploratory work would be conducted to the east of the No. 5 and No. 6 Internal Winze Shafts. Prior to the exploratory work it was also stated that this portion had only been slightly developed, and a few widely spaced drill holes were completed. From these intersections it became noted that a mineralized zone was indeed discovered but carried low gold (Au) values. By the following year it became reported that most development undeeground was started on January, 1960.
Work within the Wright-Hargreaves Mine was continued by further development, and exploratory work on the six new levels opened from the No. 6 Internal Winze below the 7,200-foot level. A total of 3,173 feet of drifting was completed in which 953 feet was done in ore averaging 0.674 ounces of gold per ton across drift widths. Further development of the favorable structure was rather completed, and had needed more exploratory work at the time that was done below the 7,200-foot level. The total drifting that was done on these levels had amounted to 3,494 feet that was entirely in ore averaging 0.615 ounces per ton across drift width from 1957 to 1959. During 1959, the development done on the upper levels had once again resulted in new ore for a distance 232 feet, with an average of 0.498 ounces of gold per ton over drift width. Stoping operations within the Wright-Hargreaves Mine had amounted to 36 of the 51 stopes down to the 7,200-foot level. Mining operations during that time period had also commenced on the six new levels below the 7,200-foot level. The total lateral development completed had amounted to 3,828 feet of drifting, 1,599 feet of crosscutting, and 2,297 feet of raising. Much of this had continued to increase the total development footage to 254,045 feet of drifting, 90,892 feet of crosscutting, and 76,617 feet of raising. Diamond drilling had amounted to 59 underground drill holes, totaling 14,780 feet in length that year. Unbroken, and Broken ore reserves within this time period had stood at 296,471 tonnes containing 0.411 ounces per ton by the end of 1959. Prior to this the total ore reserves
No additional development or exploratory work was done during 1959, on the Kirkland Townsite Mine. Mining that was done had mainly been confined to small ore shoot within the Subsidiary Structure of the Wright-Hargreaves Mine. From this development it became stated that the company produce 1,970 tonnes of ore, in which 710.272 ounces of gold, and 168 ounces of Silver were recovered.
Production that was achieved had been process under agreement with the Lake Shore Mines, Ltd. and it Mill. A total of 170,220 tonnes of ore was produce, which recovered 69,000.996 ounces of gold, and 17,338 ounces of Silver. Ore which was treated had average 0.421 ounces of gold per ton, and the extraction was at 96.3% of the total capable milling time at the Lake Shore Mine. From all processing the mill had treated this ore at an average of 466.4 tonnes of ore per day, and had produce a gross value of $2,329,113.00.
1960
Stoping within this time period of operating was done on 39 of the 51 stope sections within the Wright-Hargreaves Mine. Most of this development was completed on the main levels down to 7,200-foot level below the surface, and on all six of the new levels below the 7,200-foot level. From all production it was strongly reported that 29,794 tonnes was taken from development, and the six new levels that were now opened up.It had proven that the six new levels had help with the average content of low grade ore that was taken from the upper levels. With the mine still producing good ore it was also stated that lateral work amounted to 2,510 feet of drifting, 812 feet of crosscutting, and 1,367 feet of raising. From this development the total footage in all lateral work had comprised of 256,555 feet of drifting, 91,704 feet of crosscutting, and 77,984 feet of raising. DIamond drilling from the Wright-Hargreaves Property had consisted of 48 underground drill holes, totalling 11,504 feet. An additional 8 underground drill holes, totalling 4,210 feet was done by the Wright-Hargreaves, and Sylvanite Agreement. The total ore hoisted within the operating year of 1960, was known to have amounted to 153,002 tonnes of ore from stopes, and 11,983 tonnes from development. Ore reserves of unbroken, and broken ore had rather not change as the total reserves were at 255,453 tonnes of ore containing 0.410 ounces per ton. From all indicated ore reserves, the total had amounted to 343,713 tonnes containing 0.398 ounces per ton from probable ore, and the present unavailable for mining ore.
Lake Shore Mines had continued to treat the ore from the Wright-Hargreaves Mine under joint venture milling agreements. It was during the time period of 1960, when the Lake Shore Mill had treated 164,985 tonnes containing 0.410 ounces of gold per ton. Milling was done at a daily production rate of 450.8 tonnes of ore with an extraction capability of 96.3%. From all production the gold recovery from the Wright-Hargreaves Mine had amounted to 62,635.911 ounces of gold, and 17,723 ounces of silver.
1961 -
Some new construction was completed from underground when a new concrete bulk head was made on the 3,400-foot level. Most of this was caused due to the impound water draining from the Sylvanite Mine, and a new 4-inch discharge line was installed in the No.4 shaft to handle the increase flow of water. This was also followed by the installation of a new pump on the 700-foot level in order to handle the draining from the upper Sylvanite Levels.Prior to installation this had also included the installment of a 4-inch discharge line to the surface. A total of 33 stopes became worked from the 51 stopes that were developed down to the 7,200 foot level, and on all six new levels below that level. Production during that year had amounted to 31,045 tons. which was obtained from mining, and a small amount of development on the levels opened up in the No. 6 Winze. Lateral development was slightly decreased which had totaled 554 feet of drifting, 208 feet of crosscutting, and 1,381 feet of raising. Underground drill holes during 1961, had consisted of 35 holes, totalling 7,898 feet in length. There was also an additional 6 holes, totalling 3,157 feet, that became drilled from underground by the Wright-Hargreaves, and Sylvanite agreement. The total amount of hoisting done in 1961, had amounted to 153,875 tonnes from stoping, and 5,203 tonnes from development. Broken and unbroken ore reserves within this time period had totaled 220,078 tonnes, along with probable ore, and unavailable for mining at 314,568 tonnes. It was also within that time period when the total development for drifting, and raising in new ore had amounted to 5,720 tonnes containing 0.30 ounces of gold per ton on the upper levels.
Milling operations under agreements had continued onward at the Lake Shore Mine Mill within 1961. A total of 159,078 tonnes became processed, which recovered 58,891 ounces of gold, and 15,090 ounces of silver. Processing of the ore had average a daily tonnage of 435.8 tonnes per day within the operating year of 1961, and extractions of the capable capacity was 96.1% at 0.385 ounces of gold per ton. The total broken ore reserves were rather reduce by 7,575 tonnes to a total of 37,948 tonnes at the end of 1961.
1962 -
Lateral work within the Wright-Hargreaves Mine had continued when 271 feet of drifting, 1,261 feet of raising was accomplish. From this development the total footage completed had amounted to 257,380 feet of drifting, 91,912 feet of crosscutting, and 80,626 feet of raising. Mining during the year had continued to progress on 38 out of the 51 stopes on the main level down to the 7,200-foot level, and the six new levels below the 7,200-foot level. A total of 37,509 tonnes was block out from mining, and a minor amount of development on the six deep levels. Some more problems had escalated when the company face gradually declining grades in the production which was cause by the greater amount of dilution within the lower levels of the mine. Most of this was caused due to the fact that the rock pressure was far more higher, and also because the company had confined it self to the clean up of ore shoot tail ends within the upper levels. Following this it was also stated that the broken ore reserves were reduce by 6,085 tonnes to a total of 31,683 tons at the end of 1962.Hoisting that was completed in 1962, had totaled 146,370 tonnes from mining of stopes, and 3,014 tonnes from development. The total amount of diamond drilling done had consisted of 12 underground drill holes, totalling 2,886 feet in length.
A decrease occurred within the milling process during the operating year of 1962, as the ore was being treated at the Lake Shore Mill. Within this time period the mill had process a total of 149,384 tonnes of ore with an average grade of 0.364 ounces of gold per ton of ore. As milling continued at the Lake Shore Mine it was also stated that the recovery of gold had amounted to 51,720.149 ounces of gold, and 15,157 ounces of silver. Milling from the Lake Shore Mill was treating a total of 409 tonnes of ore per day, and had an extraction rate of 96.1%.
1963 -
Within this time period the company had continued to progress its operations on 38 out of 51 stopes within 1963. Most of this development, and production work was completed on the main levels down to the 7,200-foot level, and the six new levels serviced by the No. 6 Internal Winze below the 7,200 foot-level. During this time period there was a total of 35,494 tonnes that became mined, and a small amount came from developing the deeper levels. By this time the company had completed another ore-pass between the 8,100-foot level, and and the 7,950-foot level.. It was reported that production within these levels had increased significantly by producing 31% of all the ore hoisted in 1963. Improvements in grading were once again made from the unexpected values in the deep level stope sections that contained 0.4253 ounces per ton of ore produce. There was also a limited a of mining that was done within some high-grade ore that was adjacent to the No. 4 Shaft Operation. Lateral development was rather done at a slow pace when 204 feet of crosscutting was done, and 1,342 feet of raising was completed. This had once again added to the total development footage that end up totalling 257,467 feet of drifting, 92,116 feet of crosscutting, and 81,968 feet of raising. From all production it was reported that hoisting had amounted to 139,773 tonnes from stoping, and 3,227 from development.
Production that was achieved by the Lake Shore Mill had process 143,000 tonnes of ore containing 0.425 ounces per ton. From this production the mill had recovered 58,678.448 ounces of gold, and 14,568 ounces of silver. It was also at this time when the gross value for the total amount of gold, and silver produce had amounted to $2,238,846.00. Gold within 1963, was rather purchase at $37.61 per an ounce produce, and the total bullion value had combined gold, and silver together to produce a better gross value then that since 1959. It was at this time when the total daily milling capacity for the Wright-Hargreaves ore was 391 tonnes per day, compared to 435 tonnes in 1961. From all processing the mill during this time period of operating was able to produce at 96.1% of the total extraction for 1963.
Ore reserves after milling 143,000 tonnes in the year, had estimated that the total broken, and unbroken ore reserves was reduced by 23,148 tons. From this reduction it was stated that the total amount of reserves had amounted to 116,315 tonnes containing 0.40 ounces of gold per ton by the end of 1963. In addition to this, there was also new ore added to the reserves by development which amounted to 3,600 tons, and an additional tonnage of 83,252 was won from mining previously establish ore limits. Most of the production that was obtained from this development was partially confined to the deeper level stopes of the Wright-Hargreaves Mine. Other statement had stated that other additions mining from the previously establish ore limits would be small, since mining in the ore blocks at the bottom levels had advanced to a stage where accurate estimates can, and have been made. From this restriction it was likely reported by the company that mining would be rather exhausted by the end of 1954.
Some major down falls had occurred during mining operations on the previously mention stopes in 1963. It was during this time period when aggressive ground movements occurred on August, 14/15, of 1964. Most of this had occurred within the shaft's pillar region of the north vein system, and centering at about the 3,900=foot level. These two disturbances were partially caused due to the movement of one or more fault blocks. This had contributed several localized rock burst that had continued for two days with gradual diminishing intensity. Two of the works which were working in the stope on the 4,050-foot level were fatally killed. In terms of this, it became reported that a dozen places on the north vein had experience many rock falls that had luckily not caused any more injuries or fatalities. From this down fall it was stated that material damage to the mine was extremely extensive, and heavy. It was at this point in time when the reserves had slowly decreased also, in which the company had no choices but the close the mine. Before this closure had occurred the company continued a slow pace mining operation in recovering broken ore from undamaged stopes, and had also salvage their equipment. From mid August till the years end it was strong reported that 15,056 tonnes of dry broken ore containing 0.506 ounces of gold per ton was recovered, and milled. Expectations at the time were also aimed at recovering another 11 to 12 thousand tonnes of ore before the termination of mining on March, 1965. Prior to this the company had also salvage most of the piping, equipment, tracks, and cable with the broken ore reserves that remained. Within this time period a total of 32,398 tonnes was mined, and a small amount came from development work on the bottom six levels of the No. 6 Internal Winze. Hosting that was done during that year had amounted to 97,396 tonnes of new ore in stopes, and 2,528 tonnes of ore from development.
All the ore from the Wright-Hargreaves Mine Site had continued to be treated at the Lake Shore Mine Mill in 1964. From all production the mill had ended up treating 99,924 tonnes of ore during that year of operating. An average of 0.4762 ounces of gold was produce per a ton of ore milled, and the daily production rate was at 273 tonnes of ore per day. In all processing the mill had recovered a total of 45,968.659 ounces of gold, and 9,996 ounces of silver.
1965 -
Mining was continued at a small scale due to sever damage that was caused from ground movements, and rock bursts. Operations during this time period were mainly confined to small amounts of broken ore reserves before being abandoned, and subsequent underground operations were confined to recovering broken ore, and salvaging equipment. A total of 12,666 dry tonnes of broken ore became drawn from the stopes, and milled. From all production the mill was able to recover 5,627.33 ounces of gold, and 2,159 ounces of silver, which obtained a gross value of $215,369.00. By the time the mine had produce 9,934,427 tonnes of ore since the commencement of mining operations in 1922, which contained a gross value of $160,634,103 in gold, and silver.
Further studies were also made in regards to the re-treatment of tailings, which was done by a joint venture agreement with the Wright-Hargreaves Mines, and the Lake Shore Mines. Most of this was done in finding was to recover the tailing in a commercial feasibility of retreating old mill tailings in the main Kirkland Lake Basin. This was also followed by experimental runs
