By 1908, the Kerr Lake Silver Mining Company was further developing this mine when the shaft on the No, 3 vein was being sunken to the fifth mine level, at depth of 321 feet below the surface. Development on the second mine level was strongly known to have been constructed by a crosscut that was driven west for a distance of 360 feet, and had continued northwest for another 150 feet. A considerable amount of work was also taking place on the third mine level which was being opened up by a drift that extended south for a distance of 224 feet before continuing north for another 140 feet, The Kerr Lake Mining Company was also further constructing the fourth mine level that was stationed one the mine's 260 foot level, and had been opened up by a drift section that was considered to have traveled north for distance of 60 feet, while continuing south for another 170 feet. Almost all of this development was first started when a small prospect shaft was made and would eventually become turned into a winze shaft operation that was opened up by a drift on the 110 foot level, that was driven the Company's No. 1 shaft Operation. Further development of the No. 1 winze shaft was known to continue in 1909, when the Kerr Lake Mining Company had started to connect the Winze Shaft Operation with all underground mining levels. In addition, the winze shaft was now being sunken on the newly developed fifth mine level, that was being driven on the mine's 315 foot section, and had opened up by another drift that was engineered to a distance of 110 feet, then had continued south for 90 feet. The Kerr Lake Silver Mine was rather turning into a huge a development project which was obtaining production from a whack of stoping on the mine's first, second, third and fourth levels at the time. No production was said to have taken place on the fifth level at the time as it was just getting developed. by the company/
Another huge amount of construction had soon occurred when the Kerr Lake Mining Company had started further development to the north of the silver mining operation. All of this was first achieved when the company had started on another development phase which was aimed at constructing the No.7 shaft operation on a separate vein zone. The No. 7 shaft at the time was being sunken to a depth of 200 feet and had also included three ore producing levels towards its very own production and development. As development continued the Kerr Lake Mining Company also started full production from the second and third mining levels during the same year. Ore production from the second mine level that was stationed at 145 feet, had been further constructed when the company's Forman had started to open this section up by driving a drift for a distance of 580 feet, and then had continued north for another 180 feet. A crosscut section was soon being further developed when the company was now focusing on connecting the No.7 shaft operation with the No.9 vein zone that was being driven for a distance of 240 feet to the west and had traveled for another 430 feet to the east. Once the crosscut was officially completed, the Kerr Lake Mining Company had now continued on further developing this section by adding 80 more feet of drifting and soon started to expand this section by constructing a crosscut which is driven for a distance of 80 more feet to the south of the drift. Ore production from this level is mainly being extracted from the No. 7 vein by engineering several stope sections that remove the ore to be hoisted at the mill foundry.
Construction of the third mine level that's stationed at the mine's 200 foot section had mainly started to commence further development by opening this section of the mining operation up with another drifting phase. A drift within this section is commonly know to have been driven for a distance of 120 feet to the south and continues for another 140 feet beneath Kerr Lake. Another drift within this section is also considered to have been developed towards another vein structures that's known to continue towards the Crown Reserve Vein. Some sampling on this level was also being examined by the Kerr Lake Mining Company as this corporation wanted to know how rich the ore was from this location.
Further development by the Kerr Lake Mining Company was soon achieved when this corporation had started further exploring the property by constructing the railroad shaft to a depth of 83 feet. Almost all development on this level was considered to have been escalated by a drift that was driven south for a distance of 75 feet, and soon had continued to the east for another 50 feet. Company officials who owned and operated the Kerr Lake Mining Project had also developed another set of structures which included the magazine and thawing house in 1908.
In 1911, the Kerr Lake Mining Company was on another move when this corporation had completed several feet of drifting, crosscutting, and raising on this very location Most of the development was said to have comprised of 4,411 feet of drifting, 2,252 feet of crosscutting, 685 feet of raising, and also further sinking the winze shaft to about 207 feet. In addition the mine manager and the company had achieved several feet of lateral development that was strongly considered to have totalled 21,946 feet throughout this whole entire mining operation. Almost all the mining development work during the year was mainly confined to the north end of the property by the No. 7 shaft, although further production was also said to have been aimed towards the No. 3 zone by stoping out the ore. Production during 1911, had also started to take place on many different veins that consisted of 15 geological zones, 13 of these veins were also said to have been located on the north side of the property and under Kerr Lake alone.
As production started to become heavy within this deposit, the Kerr Lake Mining Company had no choice but to construct their very own ore sorting plantation that would eliminate this issue from ever happening again. All of this development would soon start to install the necessary equipment to operate this facility at full force. All of these things had included a bumping table for hand sorting, trammels, and jig table for processing the ore before being shipped for further processing. Company officials also didn't have their very own milling facility, so a contract was soon made with the Nova Scotia Mining Company for milling the low grade ore, and an aerial tramline was also constructed from the mill to the property of the Kerr Lake Mine. Not much production was soon commenced from this mill as the Nova Scotia Mining Company had went through a major failure that had only produced a few thousand tons of ore for the company.
Company officials who owned and operated the Kerr Lake Silver Mine, would end up paying their first ever dividends on August, 1st, 1912, that was known for totalling $4,020,000. A huge amount of development was also reported during 1912, which had included a massive amount of drifting that had totalled 4,679 feet, another 2,235 feet of crosscutting, and 609 feet of raising was also done. The Kerr Lake Mining Company during this time period had even started expanding the No. 1 shaft that was being deepened to 512 feet below the ground from its previous 321 feet. Company officials of the Kerr Lake Mining Company had also commence further ore extractions which all came from a massive amount of stoping that was known for totalling 31,782 cubic feet. Further production was also taking place on the much known vein zones that were being blocked out on the north side of the property, and total development within this operation was now totalling 29, 679 feet of lateral work. Productions from these locations soon would have company officials extracting and producing a lot of silver which soon had processed 1,479,894 ounces from the No. 7 shaft, and also continued to extract another 261,910 ounces from the company's No. 3 shaft. Another contract for low grade ore processing was soon made with the Dominion Reduction Company, and the old aerial tramline was soon reconstructed to provide transportation from the mine to the mill.
During 1913, the Kerr Lake Mining Company was further developing this mining zone when they soon had constructed another 2,974 feet of drifting, 1,663 feet of crosscutting, 160 feet of raising and also sinking the shaft to another 186 feet below the ground. Further development within 1913, had been mainly carried out on the Flemming Vein Zone that was first uncovered within the 225 foot level of this mining operation. Ore production from this level is also considered to be within the Keewatin Formation Zone, and has been known for yielding a very promising second grade silver production. A huge amount of high-grade ore was also being extracted by the occasional usage of ore shoots that became developed within this extraction business. Further development within this section is also known to have widen the stopes and a great amount of timbering was achieved within this level of operation.
Beside further developing the Kerr Lake Mining Operation, the Kerr Lake Mining Company had soon extracted 18,252 tons of ore from this production that was being shipped to the Dominion Reduction Company's Milling Facility. In addition to this, 183,682 tons of silver was soon processed within the company's sorting plant that would end up yielding 2,109,175 ounces of silver, and had company officials pay another $600,000 towards dividends that year. Another huge change would soon make history when the Kerr Lake Mining Company and the Crown Reserves Mining Company, soon started on a whole new phase when these two corporations had obtained permission to drain Kerr Lake, and would also end up purchasing more ground that included lots Jb9 and 10, and had also purchased 33 feet of shore line by the Drummond Mining Operation This whole entire draining stage had soon expose a valuable high-grade ore body that was located under Kerr Lake, and mining had now commenced towards this vein \one by the two companies.
This whole new discovery that was uncovered in 1914, had consisted of new veins and also had discovered that many of these veins were known to be extensions to previous vein workings. Company officials had now started to increase the vein workings by adding many other discovery zones that include the Main East, Flemming, and the newly discovered lake veins. Some more production during 1913, was being aimed towards another series of veins that were classified as the No. 1, No. 2 and No. 3 vein zones. The No. 3 silver vein was said to have also been uncovered within 1914, when the Kerr Lake Mining Company had soon revealed this vein by extracting all the bottom mud from the lake basin. This vein structure was commonly considered to have been known for contributing several discovery veins that all had connected with the Main East and the Flemming Vein Zone. Prospecting within this area was also said to have been scarce as the company had never explored this mining section till the further prospected this area in 1913.Further development towards the No. 3 vein had soon started to take place when the vein was opened up by 240 feet of drifting on the mines 140 level of the No. 7 shaft. Ore production from the mine still had continued during 1914, when the Kerr Lake Mining Company had once again shipped another 18,862 tons of extracted rock to the processing plant that was owned and operated by the Dominion Reduction Company. The yield from all the milled ore had soon resulted in another 632,023 ounces of silver that was taken from all processing phase. Another amount of 2,552 tons of high-grade ore was also said to have been treated at the company's sorting plant that resulted in 1,828,424 ounces of silver from all production during 1914, and the company had yet again paid another $600,000 towards dividends.
Mining costs during 1914 had been known to rise up and down as the Kerr Lake Mining Company was pretty much paying $5.09 per a ton of rock that was hoisted to the surface from underground workings. The Company also had to pay shipment and treatment costs that were known to bee 11.6 cents per an ounce of silver that was to be processed and another charge of 25 cents per an ounce was place under administration costs.
In may of 1914, the Kerr Lake Draining operation was once again resumed by the company, any by the end of august the scow had now rested on bedrock that was near the center of the basin, at a depth of 80 feet below the original water line. Further production within this section was constantly being work on when the company had started placing new pumps along the shore line of Kerr Lake to extract the rich muddy bottom in order to commence further development and explorations. This whole mining stage was said to have been done without difficulty , until the dry out of the surface bottom had made it necessary to install a simple hydraulic apparatus to sluice down the loose material, and to cut away through the underlying clay to bedrock. A few motors had also been installed by the Kerr Lake Mining Company which were known to be station on tripods and place on the Scow. Company officials had even gotten more creative when they had soon installed a 1,000 gallon turbine pump that was stationed at the Giroux Lake Pump House, and had been used to supply water from a six inch line to the mill nozzles. Production and development was also said to have been carried out by more then 140 miners and surface workers who had obtained a position with the Kerr Lake Mining Company. No other production or development was said to have been escalated during this time period, but the newly installed machinery did however achieve huge results within the draining stage.
Company officials who had owned and operated the Kerr Lake Mining Operation had started further development of the mine in 1915. Almost all of this development had included a wide range of drifting that totalled 1,966 feet, and another 1,204 feet of crosscutting was also conducted on the mine during this time period. The No.9 shaft was also receiving further development when it was being sunken to 720 feet below the ground and had included 50 feet of raising within this whole expanding stage.
The southern portion of this mining operation was also being prospect when the Kerr Lake Mining Company had completed another expanding phase on the No. 3 shaft, which was being sunken to a depth of 240 feet during 1915, Almost all construction within the No, 3 shaft was soon being conducted on the mines 320 foot section that was opened up by extended drifts to the east and to the west, and had soon encountered another strong vein. At about 400 feet northwest of the shaft, a winze shaft was also being sunken to a depth of 50 feet within the 320 foot level. Further development of this section had included opening the winze shaft operation by driving a 75 foot drift along the Keewatin formation and below the daibase sill. The Kerr Lake Mining Company during this time period was also performing further construction of the second level of the No. 3 shaft operation, that's opened up by a long crosscut which was driven from the south central of the property to the southern boundary zone. Prospecting within this operation was also considered not to be so encouraging like the rest of this mining operation that has proven to have produced a significant amount of silver throughout it whole entire life span. A large amount of constructing was soon to have continued on the No. 7 shaft, when the Kerr Lake Mining Company soon started further production on two veins that were located within the 140 foot level of this mining operation. In general the company had continued to commence further production and was once again ready to hoist another 47,436 tons of extracted ore from the Kerr Lake Mine Workings, and was soon to be shipped to the Dominion Reduction Company's Mill Site by aerial tramway. Further processing of the ore had soon treated 2,036,962 ounces of ore that was being done at a cost of 11.09 cents per an ounce of silver produced. Nothing seem to stop the Kerr Lake Mining operation when another huge amount of ore was soon uncovered within a huge drilling phase that still had a total reserve 4,172,400 tons of rock to be processed and treated.
The continuation of all development on the Kerr Lake Mine was also commencing in 1916, when the Kerr Lake Mining Company had further drilled this operation to retrieve the high-grade silver ore. During the year, the Kerr Lake Mining Company was mostly confined to underground development which had totalled another huge amount of footage towards this production. Drifting within the mine was now being increased to 1,975 feet, the company soon started on a whole new phase of Cross-Cutting that totalled 1,737 feet, and raising was estimated to have been increased to 189 feet. Company officials of the Kerr Lake Mining Company, would soon decided to expand the mining shaft by sinking the Main Shaft to 967 feet during 1916. Almost all construction that was commenced by the Kerr Lake Mining Company during that year was in full development mood that included 4,056 feet of lateral work on the Kerr Lake Mine. A massive amount of stoping was also achieved by the company throughout the many years of operating, which would end up totalling 44,008 feet towards all production on the Kerr Lake Mine by 1916. Company officials for the first time ever had soon adapted another method of mining towards this production by side-cutting the vein for a distance of 1,189 feet. The Kerr Lake Mining Company soon started a whole new hoisting procedure of 55,850 tons of ore that was to be transported to the surface from the mine workings at a cost of $3.68 per a ton. Ore extraction from the mine during that year was said have treated 45,743 tons of ore, which the remaining 13,107 tons was thrown into the waste pile that already had estimated to have 50,000 tons of waste rock. Nevertheless, Company officials soon started yielding another profitable silver extraction from the sorting plant that resulted in 2,433,793 ounces of silver towards the company's revenue. As development and sinking was achieved, the Kerr Lake Mining Company soon face other issues when the deeper workings had constantly flooded, which soon resulted in the Installation of a De Laval 3 stage, 350 gallon Centrifugal Pump that was electrically driven, and had been installed within the main shaft, on the 225 foot level, which was aimed to handle the flow of water within the mining operation.
In 1917, the Kerr Lake Mining Company was very well known for producing a large amount of silver from the Dominion Reduction Company's Mill, that totalled 2,551,345.95 ounces of silver, and another whooping 89,453.63 pounds of cobalt. Further explorations that were achieved within 1917, had included a total of 3,120,400 tons of reserves that were still to be mined within the Kerr Lake Mining operation. The company at the time was also focused on opening up another tunnel within the first level that was being driven towards the Drummond Fracture Zone, which had constructed a considerable amount of development within this section. Almost all development and extraction of the rich ore was being confined to this location, as the Kerr Lake Mining Company would open this section up by a drift that was driven 1,268 feet, another small section of cross-cutting was being drilled and blasted to 588 feet, and the last stage of raising had been constructed to 1,197 feet. Company officials who had ran this massive producing silver mine soon started to commence further production by extracting a rich silver ore deposit that yield 67,112 ounce of pure treated silver, which was taken from a smaltite vein that's located on the eastern extension of the Flemming Vein. Company officials had spent a small sum of money towards all development, transporting, and processing that had minus $26.75 from the company's revenue.
Almost all workings within the Kerr Lake Mine, had been mainly focused on further exploring the veins in hopes of fishing out another promising vein within 1919, when the Kerr Lake Mining Company had need more reserves as the production within the mine was slowly becoming exhausted. However, nothing encouraging was found from these exploration phases and the company was also only able to treat a total of 492,976 ounces of silver that was processed at the Dominion Reduction Company's Mill, which had came from all extraction within the Kerr Lake Mine Zone. The company was also milling their very own ore at the sorting plant that was not considered to have a profitable yield but it still contributed towards production. Company officials within 1919, would also process and treat another huge amount of ore which soon produced 1,482,649 ounces of silver and 90,586 pounds of cobalt by August 31st of that year.
Another huge development phase was soon to take place when the Kerr Lake Mining Company commence further construction of the mining operation, which soon had totalled 2,383 feet of drifting, crosscutting, and raising. Further drilling within this zone didn't encounter any more promising silver veins, and the work was being mostly explored on the newly developed Drummond Extension that would result in another 400,000 tons of ore towards all production within this mining operation. A total of 57,779 feet of lateral development was achieved by the Kerr Lake Mining Company from the start of the operation, till 1919 Nothing else would take place during that year besides further prospecting the rich silvery land in hopes of locating another promising reserve to continue mining operations at the Kerr Lake Mine.
The Kerr Lake Mining Operation was rather experiencing a massive shortage of ore when the company had only produce 956,050 ounces of silver, 42,654 pounds of cobalt, and another 34 pounds of mercury that was all shipped to two different milling facilities within 1920 .Nothing encouraging was said to have been reported during 1920, besides some development work that totalled 3,969 feet of extra lateral development that was now sitting at 59.891 feet throughout the whole entire mining operation. Once all of this had became completed, the Kerr Lake Mining Company was once again on another mission to explore the newly developed workings that were being driven with the ore shoots. Some production from this exploration was soon to be commenced when the Kerr Lake Mining Company had uncovered a medium scale high-grade deposit zone that was located along the ore shoots of the mine. Further production was soon to continued when the company started to hoist 17,960 tons of extracted ore and 5,191 tons of waste from inside the mine. The Kerr Lake Mining Company started hauling away the much needed pay ore that was delivered to the branch line, and then had been transported to the contracted mill site which had processed a total of 23,150 tons of ore with a much lower grade of 12.5 ounces per a ton. Company officials who had ran this operation soon started to face a major crisis when the stock of the was becoming more and more exhausted as production continued on. They eventually had no other choice but to option another neighboring mining claim during that same year in order to escalate further production. This historical discovery was encountered when the Kerr Lake Mining Company had started on a whole new drilling phase from the No. 3 shaft that was being establish towards the Hargraves Silver Mining Operation. The Kerr Lake Mining Company would also make a new purchase during that same year when it had bought out the Hargraves Mine for a whooping $16,250 from the previous owners. Some royalty was also offered to the owner within a few months of getting this mining operation underway and processing the rich silver ore that was still to be extracted from this location.
1922- Kerr Lake Mining Company, Limited
In total production the company was well recognized for producing a total of 27,005,276 ounces of silver, and had also paid a total of $10.195,000 in dividends at the end of 1922. For the most part the company reported that all mining operations became closed down on February, 1, 1922. It was rather in the 1920's when the cost of producing silver was at $56.04 per an ounce, which included mining, development, shipping, treatment, administration, and general expenses. All development work in total was report to have consisted of 12.2 miles of drifting, crosscutting, raises, winzes, and shafts.
Much of the vein within the Kerr Lake and Crown Reserve Mines are known to be continuous, with much of the boundaries of the claims being accidental. Some of the vein systems within the Kerr Lake Mine were also reported to have extended into the Crown Reserve Mine Site. Most of this was determined by the Big Chamber that's found on the Carson and Crown Reserve Properties. It also is known to be intersected with the No. 10 vein, in which is known as the Ross on the crown reserve. The last vein in which extends from the Kerr Lake Mine into the Crown Reserve Mine is known as the Fleming. that has the same name on the Crown Reserve Property.
Some of the main veins that are associated with the Kerr Lake workings are known as the No. 10, Fleming, No. 3, No. 7, big chamber, Main East, and MacDonald. In addition to this a separate record was also reported to have not been kept till about 1911. One of the most important veins within the Kerr Lake Mine was known as the No. 3 vein zone that was situated on the southeast corner. It was rather reported to have also been one of the first veins to be discovered within the Kerr Lake Property prior to development. In addition to this, the vein was reported to have been almost mined out by August, 10, 1910. Much the No. 3 vein within the Kerr Lake workings was also a high end production vein which produce between 2 to 3 million ounces.

Another vein known as the No. 3 vein is one of those interesting veins that occurs within the Nipissing Diabase. Much of the vein occurs in the Nipissing Diabase and is strongly considered to pass down into the Keewatin, in which the workings have been explored at 150 feet below the diabase. Within the Diabase the ore-shoot was also stated to have not extended to the bottom of the sill, but had came to about 125 feet from the bottom. Other statements from the company had assumed that the Diabase has its own thickness of 1,000 feet. Generally, this can be seen from the stope section that the ore-shoot extends upwards into the middle of the sill. Other statements had suggested that the sill may have extend to the top but has been long eroded. From any other mines in the Cobalt Camp it was suggested that an important ore-shoot is known to occur in the center of the diabase sill
It was rather stated that the No. 3 vein, within the fifth level had also carried gold in the Keewatin that valued between $1 to $18. In addition to this, the No.3 vein was also considered to have been very rich along the surface of the Kerr Lake Project. Much of the vein within the Adit level up to the surface was stated to have treated 170 tonnes averaging $1,500 per a ton. Some places of the No. 3 veins are considered to also occur in striations which dip gently to the south. This rather proves that some more or level horizontal movement had take place on along the fractures where the No. 3 vein occurs. Much of the South End of the Kerr Lake Property, is know to also be occupied by the No. 3 vein, which is known to slip into different branches, and continuous south in the Hargrave Property.
Vein No. 7 was stated to have an ore shoot that was 700 feet in length, and it was rather stated that 60 foot drift had produce 94,000 Oz's from the No. 7 vein.
Besides the No. 7 Vein, the Big Chamber Vein is known to have it's own length of about 175 feet on the 140 foot level. . It also known to extend into the Crown Reserve Property, where the vein is determined as the Carson Vein, that has a length of 275 feet. More so the total length of the vein that is know to expand from the Kerr Lake Property in the Crown Reserve has a length of 450 feet. Production from the Big Chamber was stated to have produce at least 1,488,401 Oz of Ag, but the records of production for this vein were not completed to its fullest. Much of the Big Chamber Vein within the Crown Reserve Property was stated to have produce a significant amount of silver that totaled 9 million ounces which was nearly half the production of the Crown Reserve Mine. There is also known to be a trough within the Keewatin Series of the Kerr Lake Property that's indicated in the plan below. The whole entire axis of the trough is considered to also pinch, and strike to the North within this mining project. A pure example of this trough or depression call also be observed on the 140 foot level of the Kerr Lake Mine. Generally, the trough within this mine is stated to have been formed by erosion which was later filled in with the Cobalt Series. Other statements had stated that it does not seem to have been formed by the folding after the Cobalt Series was laid down. All of this is rather determine by the lower bed of slate like greywacke in which is shown on the 140 level of the Kerr Lake Mine, and the 100 foot level of the Crown Reserve Mine.
All the veins within the Kerr Lake Mine, and Crown Reserve are stated to also cross this trough, and run down the axis of the trough A huge amount of difficulty was also experience in the process of determining where the contacts were between the Keewatin and Cobalt Series. Much of the Cobalt series is considered to rest on the Keewatin Basalt. It also considered to be associated with a Keewatin Cherty Iron Formation, which occurs on the Northeast of the property. Much of the company plans are also known to show some of the contacts, that became determined by Mr. G.R Whitman who might of been the mines geologist at the time. Most silver production that was taken by this company had occurred within the veins that were under Kerr Lake. Some silver production also had occurred within the No. 3 vein system at the southeast corner of the property. A plan of the Adit level also shows the strip of the land that is under Kerr Lake.
Mining operations at the time were mainly being operated from the No. 7 shaft operation on the northwest side of the claim, and from the No. 3 shaft at the Southwest corner. It prime usage was mainly being used in mining much of the silver ore-bearing material from what was known as the No. 3 vein zone.
Description of the No. 7 Shaft Workings
The eighth level of the No. 7 shaft was known to have been cut on the 325 foot level, in which was driven within the Keewatin. This level is rather inaccessible from the workings as it was reached by an internal winze shaft on the 275 foot level. A small amount of work was reported to have been done on the Flemming Vein area within the winze level at 325 feet. It was rather during development when the level had intersected with a short shoot of good ore.while the rest of the vein was barren in this section.
Another known as the Seventh level became driven on the mines 275 foot level, which is also inaccessible as its reach from an Internal Winze shaft on the 225 foot level. In 1922, this area was rather reported to have a small amount of development work done on it. Most of this section became driven by a drift within the Keewatin rocks as the Flemming Vein was being followed in this section. Development on this level became very satisfactory as it showed mill ore, and high-grade pockets that stretch for a length of 200 feet. It was also during that time period when the west section of this level became examined and was reported to also be entirely in Keewatin, with a narrow bed of banded Keewatin Iron formation.
Development of the sixth level was cut on the mines 225 foot level which was known as the Big Chamber vein section.The Big Chamber Vein is rather known as the easterly extension to the Crown Reserve Property, that entirely in Keewatin. Another vein was also intersected during development which became identified as the Fleming Vein, which was describe to have been only partly in Keewatin. and Cobalt Series. Production from the Keewatin side of the Fleming Vein was reported to have produce a significant amount of good ore. It was also reported that the same bed of banded Keewatin Iron formation is known to also occur on this level. Much of the Keewatin Iron Formation is also considered to be impregnated with zincblende, and iron pyrites. Generally, the cobalt series is considered to form a belt that is from a few feet to 135 feet in width within the north boundary of this property.
Additionally, the third, fourth, and fifth levels of the No. 7 shaft are considered to be within the same geological formation at depths of 165, 175, and 190 feet. At the time this level was mainly being opened up in order to follow the Fleming vein in which had expanded these levels by a drift for a length of 600 feet. At the back of the stope section the Fleming vein was reported to have still be seen, and had its own width of 15 inches. Much of the vein is also considered to dip to 67 degrees to the south, and at the east end this vein is considered to be a fault dipping 60 to 70 degrees eastward, which also apparently had cut off the silver from the Fleming Vein. In addition to this, the fault section was reported to have contained Iron Pyrite, Calcite, and quartz, which is also rusty. In certain places the Iron Pyrites which occur are considered to be banded with a number of bands that reach as high as 40 bands. At one point where it meets the fleming vein, its considered to also consist of 2inchs of calcite, four inches of banded pyrite, and half an inch of gouge. In other places this fault is consider to carry little calcite together with the gouge and fault breccia.
The Second Level at 140 feet is rather stated to be the most comprehensive level within the mining operation. More so this level gives a good demonstration of the complexity within the vein system, Its also within the elevation as the 100 foot level of the Crown Reserve Mine, with the two levels being connected by the Carson Vein. Additionally, its also reported that the Fleming Vein within this section has barren parts which have a width of 12 to 15 inches. Not to mention it was also stated that the trough to the west end of this mining operation is considered to be well defined on this level. In addition to this, the No. 7 vein is stated to also be followed along the east side of the trough, and is known to turn westwards, before crossing the trough. At the east end of this level the mine is strongly known to consist of chert where a bedding of chert was notice in this section. Further descriptions of the chert had stated that it was impregnated with iron pyrite, zinc blende, and galena, and is also carbonaceous. There's also another fault section which was reported to have occurred on the north-west corner of this level, and dips 32 degrees northward, and has a reverse displacement by at least 5 feet.
Now the first level at 90 feet is considered to be all in cobalt series rocks that is known to be opened up to the south end. Work within this section was strongly stated to have been done on the Nipissing Diabase, in which is known to show that the contact of the diabase and adjacent rocks are an unusually irregular one. Much of the vein material on this level is known to have work a vein called the office vein which is entirely in smaltite, and calcite was stated to have not been productive in silver values. It also known to have followed the No. 7 vein in which was stated to have consisted of several veins that join into one or had branch together into several veins.
By 1926, the Kerr Lake Mine was rather slowly becoming even more exhausted when the company had only extracted 13,200 pounds of ore from the mine. All of this was said to have contained a very low silver extraction that only had totaled 9,050 ounces of pure treated silver. Further development during that year was mainly being confined to the mines 90, and 140 foot levels, as the company started to expand this section of the operation by adding 30 feet of drifting, and 129 feet of raising. Further construction during 1926, had also continued on a sub-level that was opened up between the 90 and 140 foot levels. Company officials and their well established hardworking mines had started to open this section up by constructing 30 feet of drifting, and 79 feet of raising that had opened up more workings towards high-grade veins. A considerable amount of branching and side-slashing was said to have been accomplished within this vein structure zone. No other work was said to have been commenced by the Kerr Lake Mining Company when all mining operations became suspended and abandoned at the beginning of 1927, and little to almost no work was done by other mining company's prior to this mine being abandoned.
1937 - Comet Leasing Company - Production amounted to 220 tonnes of low grade, and 25 tonnes of high-grade silver-cobalt ore.
Production followed by explorations had resulted in 40 feet of surface trenching, and 80 feet of shaft raising. Ore that was shipped from this site had amount to 220 tonnes of low grade, and 25 tonnes of high-grade silver-cobalt ore.
1938 -Comet Leasing Company - Production amounted to 2,000 tonnes of high-grade Silver-Cobalt Ore.
Some more changes would occur when the company had sunk a two compartment shaft to a depth of 90 feet below the collar. As the shaft continued at depth it became reported that a level was establish at 35 feet. Most of this development would open up the level by 100 feet of drifting, and 20 feet of raising. Prior to sinking this shaft the company would also construct a hoisting room, which resulted in the shipment of 2,000 tonnes of high-grade silver-cobalt ore.
1939 - Comet Leasing Company - Production amounted to 26 tonnes of ore, and 380 tonnes was shipped. Most of this was done in preparation of testing, and sampling the ore.
The Kerr Lake Silver Mine was undergoing a small amount of development, and production within the operating year of 1939. Most of the development work within this time period of operating was aimed at expanding the surface tunnel for a distance of 18 feet. With much of this development completed, the company would end up exploring this area further when 50 feet of crosscutting, 93 feet of drifting, and the sinking of the No. 5 extension winze was completed to a depth of 54 feet below the second level. Production from this mine had totaled 26 tonnes of ore, while 380 tonnes of ore was taken from the stockpiled, and shipped in 1939. Employment within this mining operations had mainly consisted of 8 work personnel who became hired under the direction of James .H. Price.
1941 - Comet Leasing Company
Mining Operations by the Comet Leasing Company were rather being done under leasing agreements with the Kerr Lake Mining Company, Ltd. By this time the company had continued to operate its Kerr Lake Silver-Cobalt Project throughout 1940. The total development footage for that year had consisted of 175 feet of drifting, and 30 feet of raising. Exploratory stages on this property in 1941, had mainly totaled 1,600 feet of diamond drilling from underground, and 446 feet from the surface.
1942 - Comet Leasing Company
Mining operations at the Kerr Lake Mine had resumed operation in which the property was leased to the Comet Leasing Company. It was this property along with the Lafrano Property that became leased with mining operations starting at the beginning of the year, and closing down on October, 28th, 1941. Prior to this the Comet Leasing Company was owned by James .H. Price of Cobalt, Ontario, Canada.
By this time the company had carried out 100 feet of surface trenching to a depth of 3 feet. Prior to this underground production also had resumed when much of the backs, and pillars became removed. Diamond drilling had also been carried out when four holes, totalling 125 feet were drilled from the surface that year.
Another property known as the Lafrano was also operated under a leasing agreement before it was drop by then end of July, 1941. It was during that time of exploring this site when 20 feet of surface trenching was completed to a depth of 3 1/2 feet. Much of the bulk sample material which was obtained from this section had been shipped to Deloro for treatment, and head-grade testing in 1942.
1947 - Leased by Madusa Mines, Limited
It was rather in 1947, when the Madusa Mines, Limited was incorporated in order to operate the Kerr Lake, and Crown Reserve Properties. At the time it was rather stated that agreements became made with the Kerr Lake Mines, Limited which became known as the Kerr Lake Lease. All mining operations were rather being carried on by open stopes which had broken into the Basin of Kerr Lake. For the most part all development during that time period was confined to the 175 foot level, as 28 feet of raising was reported. Production from this development phase had resulted in a shipment of 600 tonnes of ore that was sent to the Silver Cliff Mill. At the time it was rather stated that the mill was owned and operated by a separate company known as the Ausic Mining and Reduction Company. Other construction which follow suit prior to development had also place construction phase in developing two small sized head-frames, with two hoists.
1948 - Leased by Madusa Mines, Limited
Operations at the Kerr Lake, and Crown Reserve Properties were being carried out from the main east stope shaft, that was located on the south edge of Kerr Lake Basin. Much of the development during that time period had consisted of 12 feet of raising that was done on the 125 foot level. Some more raising that totaled 86 feet was also done on the mines 170 foot level. In addition to this, the company would also sent a total of 1,170 tonnes of ore to the Silver Cliff Mill, and to the Coleman Mill that was owned and operated by the Silanco Mining, and Refining Company. In addition to this the company had also hoisted some cobalt ore in which was reported to have been stockpiled.
1949 - Leased by Madusa Mines, Limited
Production from the Kerr Lake and Crown Reserve Mines had continued, when the company operated these two silver-cobalt projects from April, 15 to October, 30, 1949. Mining within this time period was confined to what is known as the Main East Stope Shaft. Development within the mine workings had consisted of 37 feet of drifting, and 60 feet of raising on the 90 foot level. Another 21 feet of drifting was also completed on the 130 foot level during this time period of operating. From all production the company had ended up hoisting a total of 600 tonnes of mill ore that was stockpiled.
1953 - Cobalt Consolidated Mining Corporations, Ltd. had Acquired the Crown Reserve, Kerr Lake, Penn-Canadian, and Foster Properties from Penn Cobalt Silver Mines, Ltd.
Cobalt Consolidated Mining Corporation, Ltd. had acquired the Crown Reserve, Kerr Lake, Penn-Canadian, and Foster Properties from Penn-Cobalt Silver Mines, ltd. Each of these claims were rather apart of a group on Lot. 3 and 4, within Concession Iv of Coleman Township. Most development during that time was confined to the Crown Reserve and Kerr Lake Claims on Lot. 3. Examinations of the workings had reported that there was a connection made between the 200 foot level of the Crown-Reserve, and the 225 foot level of the Kerr Lake Mine. There was also the 100 foot level of the Crown Reserve, and 140 foot level of the Kerr Lake Project that became connect to each other.
Development in 1953, was mainly being confined to the 140 foot level, when 155 feet of drifting, and 316 feet of raising on the Kerr Lake Property. Another level at 225 feet of the Kerr Lake Project also became expanded by 211 feet of drifting, and 110 feet of raising. Diamond drilling on the Kerr Lake Silver-Cobalt Property had consisted of 43 underground drill holes, totalling a length of 3,672 feet. From both combined operations the company would end up hoisting, and shipping a total of 10,895 tonnes of ore from both mining operations combined. For the most part this Silver-Cobalt bearing material was also shipped for treatment to the Colonial Mill.
1954 - Cobalt Consolidated Mining Corporation, Ltd.
Mining operations during 1954, were mainly carried on from January, to February, 10th, and April,19th to December, 30th, 1954. The total development footage during 1954, had amounted to 222 feet of drifting, and 705 feet of raising on the 250 foot level. A small amount of development had also taken place on the 175 foot sub-level, in which 67 feet of drifting was completed. From this development the company would end up hoisting a total of 13,149 tonnes of Cobalt Ore that was treated at the Colonial "104" Mills. Even more diamond drilling would be conducted when 14 underground drill holes, totalling 852 feet in length were completed.
1955 - Cobalt Consolidated Mining Corporation, Ltd.
It was in 1955, when mining operations at the historical Kerr Lake Property had continued from April, 11 to December,9th 1955. Most of the access during that time of operating this site was being done through the No. 1, vertical, two compartment shaft on the Crown Reserve Property, which has a depth of 320 feet. Development on the historical Kerr Lake Property had mainly consisted of 242 feet of drifting, and 117 feet of raising on the 175 foot sub-level. A small amount of raising that totaled 19 feet was also reported to have been completed during this time period of operations. Mining operations were officially ceased, and most of the work was being completed on the Foster Property during that time of operating.
