Changes to the ownership of the property were made in 1939, in which Jerome Gold Mines, Limited had acquired 2,180 acres of prospect land from the Consolidated Mining Corporation of Canada, Limited who was heavily into silver-cobalt ores. This take over had rather resulted in further exploratory work when diamond drilling was carried out and a plant for sinking the shaft was constructed on the Jerome Gold Property. As preparations were being made towards the plant the company would also sink the first exploration shaft on the main vein zone that was vertically sunk by hand steel and was made into three compartments on historical claim S32070. This would later change when the much needed power source was adapted to the property that made sinking the shaft much more easier as it had already made it's way to the 550 foot level by August, 1939. Some of the most productive levels at the time were establish on the mines 200, 350, and 500-foot horizons. Diamond drilling that was done had rather amounted to 29 surface holes, totalling 7,906 feet, and 62 underground drill holes totaling, 3,430 feet in length on the main vein zone of the Jerome Gold Mine Project. Most drilling at the time was very low in technology and could only reach a certain depths so this why prospect shafts were put down on veins to explore the geological vein structure and characturistic further.
Development work carried out on each level in 1939
200-foot level- 551 feet of drifting, and 205 feet of crosscutting
350-foot level- 572 feet of drifting, and 185 feet of crosscutting
500-foot level- 1,169 feet of drifting, and 183 feet of crosscutting.
Even the demand for buildings was now being place under construction when the hoist-house, head-frame, powerhouse, power magazine, cap-house, office and warehouse, staff house, bunk-house, and cookery was being built. In addition to This, the mining plant at the time had consisted of 300 H.P Ruston and Hornsby 6 cylinder desiel engine, that was directly connected to a 1,450 cubic foot Belliss and Morcom Air Compresor. This would also included a 30 H.P Ruston and Hornsby, 4 cylinder diesel engine, driving 230 Volt generator for pumping, and lighting purposes, and Ingersoll Rand 9 by 8 inch, double drum air hoist.
No additional shaft sinking at the time was done as the No. 1 Veertical Three Compartment Shaft was down to the 550-foot levels as mining and exploratory would commence at a much larger scale in 1940. Development work at the time was mainly confined to the three ore producing levels at depths of 200, 350, and 500 feet below the surface. Other majors plans were made prior to the end of 1940, which had been aimed at further sinking the Jerome No. 1, vertical three compartment shaft operation to greater depths. The total amount of underground diamond drilling had also amounted to 407 holes, totalling 12,063 feet in length. Some more changes would be made when the Jerome Gold Mines, Limited had made preparations for ordering the necessary equipment for the 500-tonne cyanide milling facility, and much of the deliveries of this material were made by at the beginning of December.
The total development footage on all levels in 1940
200-foot level -3,104 feet of drifting, 569 feet of crosscutting, and 145 feet of raising.
300-foot level- 3,619 feet of drifting, 704 feet of crosscutting, and 413 feet of raising.
500-foot level- 2,851 feet of drifting, 355 feet of crosscutting, and 431 feet of raising.
n 1941, 16 additional claims were bought and 9 claims were staked prior to expanding much of the land owned by the Jerome Gold Mines, Limited at the time. Most of the land that was staked by the company was mainly situated in two different Townships known as Osway and Huffman Townships, within the District of Sudbury, Ontario, Canada. The Jerome Gold Mine at this point in time was fairly isolated and most the employees of the mine were mainly being flown by a water plane on Opeepeesways Lake, and the same method was used for obtaining supplies. Most of the fly in method was adapted when the the company had made arrangements for this service from Biscotasing to the Mine site at Opeepeesways Lake. With this costly method of transportation the Jerome Gold Mines, Limited had started their own truck road from the Mine Site to Ramsey Station on the Canadian Pacific Railway, in which was 18 miles long. Electrical power at the time was also obtained for the Jerome Gold Mine Site that was obtained from the Ontario Hydro-electric Power Commision's Plant in Shining Tree, Ontario, Canada, which was another gold district being fairywell explored.
Mining operations at the time were continuous throughout the operating year of 1941, in which the No. 1 Vertical, Three Compartment Shaft was sunk from the 550-foot horizon to a depth of 835 feet below the surface. The Jerome Gold Mine Property was rather becoming a big project that would expand the life of the mine when two new levels would be constructed at depths of 650 and 800 feet. Prior to this development, a loading pocket at the time was cut at a depth of 725 feet, in which ore and waste passes were being now driven to the new 650-foot level. Other major development that was completed included branching ore passes in order to serve each side of the mine workings, in which connections were made 200, 350, and 500-foot levels. It was at this time when the company was making preparations for production during the months of July and August, that consisted of backstoping all the known ore-shoots in order to gather 20,000 tonnes of broken ore that was stockpiled. The total broken ore reserves which was in the mine had rather totalled 28,653 tonnes, in which stoking to date had indicated a great deal of stope development would be required in order to extract the ore along the flat fault planes. Plans which were used within the mine had mainly been adapted to shrinkage stope methods that had rather paid off rapidly for the company in first administering them on the workings. Most of all the development in the mine was reported to have been low due to the major proportions in obtaining ore from the stope sections to feet the newly set up mill. Major development at the time had concentrated on the 600-foot level that had additionally developed 12,602 tonnes of ore in two shoots, averaging 0.20 ounces per tonne in cut grade before delusion. Prior to development of the 600-foot level, several narrow shoots with very limited tonnage had been indicated as the new level was further driven. Not much information at the time was rather obtained on the 800-foot level as lateral development was very minimal within this section of the Jerome Gold Mine in 1941. At the beginning of the year, the mine rather had an ore reserve of 663,910 tonnes before decreasing to 618,948 tonnes after 13,863 tonnes was taken from development ore that average 0.172 ounces of gold (Au) per ton. Diamond drilling at the time had also totalled 7 surface holes, totalling 473 feet, and 123 underground holes, totalling 4,589 feet in length. Development at the time had also progressed on all five levels that were establish on the mines 200, 359, 500, 600, and 800-foot horizons.
Development plans were rather continuous when the erection of a mill had begun within the operating year of 1941, and would be in full production by August of that very same year. Some of the major plant equipment that were add to the mill during the year had included a 1,580 cubic foot Canadian Ingersoll Rand Compressor that was driven by a 300 H.P Canadian General Electric Motor, a Canadian Ingersoll Rand 48 by 36 inch, Double Drum Hoist, driven by a 200 H.P Westinghouse Motor, a Blake type, 40 by 42 inch Allis Chalmers Jaw Crusher, a Gate Type, Allis Chalmers 7 1/2 Gyratory Crushers, and a 4-foot short handed Symons Cone Crusher. This equipment at the time had also included a Marcy-type, Canadian Vickers Ball Mill, 7-foot by 27 foot agitators, with Dorr Mechanisms, two 14 by 14-foot drum filters, and Merril Crowe Precipitation Equipment, which included a Perron Gold Press. By the end of September, 1941, the newly designed mill had rather proven to be capable of handling over the tonnage additionally planned by the company, but the tonnage was classified as to be poor if handled over 550-tonnes of ore. Milling that was done during the year was mainly aimed at test milling that had milled 58,824 tonnes of ore in which the first gold obtained had produce 8,756.888 ounces of gold (Au), at a recovery grade of 0.182 ounces per tonne. This also resulted in a recovery of silver (Ag) that had totalled 2,439 ounces in association with the gold ore obtained from mining it. There was also a tailing loss that amounted to 0.0169 ounces of gold (Au) per tonne of ore that was milled at a rate of 550-tonnes on a daily basis. Much of the circuit had also recovered a total of 967.902 ounces of gold that was taken during clean up of the milling circuit
Total development footage on all underground levels in 1942.

800-foot level- 209 feet of drifting, and 193 feet of crosscutting.
The Truck Road that was started in 1941, was officially completed by November, 1942, and had reach Ramsey Station on the Canadian Pacific Railway. No additional shaft sinking was done at this time period prior to expanding mining operations on six levels within that operating year of 1942. Development at the time had rather been entirely behind schedule and would become very minimal near the end of 1942, due to a shortage labour issues. It was also during this time period of operating when a minimal amount of development work was done on the 800-foot level that had developed 10,900 tonnes of ore in two shoots averaging 0.18 ounces of gold (Au) over 5.2 feet. Development at the time had also indicated favorable smaller shoot of ore that were still being in the process of examination to determine their full outline. Production at the time however was maintained throughout the operating year of 1942, in which the Jerome Gold Mine provided 167,936 tonnes of ore that was hoisted. It was also at this point in time when a major exploration program was undertaken at the mine that consisted diamond drilling and test sampling. Diamond drilling was also used for a wide range of reason that was aimed at expanding the working further prior to using explosives, and for exploratory purpose in defining the geological structure source of ore. In total drilling that was done on the Jerome Gold Mine from exploratory drilling, development drilling, and surface drilling had amounted to 6,993 feet in total combined length that resulted in a completion of 53,417.8 feet of drilling on this property. The total broken and unbroken reserves within this project had amounted to 328,422 tonnes, grading 0.175 ounces that had a total gold potential of 57,455.7 ounces.
Processing within the on-site cyanide mill had rather operated 92.7% of full time for the year. Most of this factor was mainly met by the curtailment in milling due to the quality of wartime material and replacement in the markets that caused gold to go down. The grade of the large tonnage mill during the operating year of 1942 was also great in consistency towards the material that was fairly well graded on average of 0.175 ounces per tonne. Other changes were being done when the removal of wet fine had used th requirement of a finer secondary screening, which resulted in improving the tonnage capacity greatly. This had also included the need for slowing down the classifier in regards to improving the recovery by 1.5% of gold tailings being lost. Major improvements kept on being made as it was also found that discarding about 100 tonnes of daily solution had gradually improved the precipitation, and reduce solidable gold tailing loss. Even more experimental work was being conducted in regards to improving the recovery of gold (Au) by flotation of mill tailings, and cyanide the concentrate further. Changes at the time had not been done as the company wanted to also recover molybdenite that was found to be in association with the ore that was mined from the Jerome Gold Mine workings. Upon examining this experimental run it was found that the Molybdenite had rather become low in recovery, and to expensive in solution that cause the company to abandon it's idea. Prior to this, the Jerome Gold Mines, Limited had also adapted new experimental run in regards to recovering the molybdenite by flotation methods. The total amount of ore that was treated through the cyanide mill would also amount to 168,628 tonnes that had an average of 0.189 ounces of Gold (Au) per tonne, and recovered 29,480.65 ounces of gold(Au), and 7,744.27 ounces of silver (Ag).
The total development footage on all levels in 1942

Major curtailment towards development and stopkng had continued onward due to the shortage in labour that had become a major factor towards this mine project for at least 8 months in 1943. Other plans at the time were being made towards continuing the shaft from the 835-foot horizon to a depth of 1,100 feet below the surface was done in September, and had reach a depth of 1,016 feet. Even more changes were now taking place when a new level of the 950-foot horizon was cut and stationed in order to be further explored during the operating year of 1943. Most of the major development work for that time period was done in relation to ceasing milling operations that had become suspended for the time being. No additional development work had been done on the new cut and stationed 950-foot level as the shaft had only reach 1,016 feet, but was still continuing to be sunk further. Development at the time was mainly confined to 200, 350, 500, and the 650-foot level at the time of hoisting much of the ore from the workings that amounted to 106,846 tonnes. Diamond drilling that was done during 1943, had amounted to one surface hole, totalling 2,065 feet in length, and one hole, 30 feet in length from underground. Much of the problem in developing new ore for that year was mainly due to the labour shortage that had place a curtailment in disclosing new ore to be mined from the Jerome Gold Mine. Total ore reserve figure for the end of 1943 had rather stood at 213,442"tonnes of ore that had average 0.166 ounces of gold (Au) per tonne that was still to be mined from this project.
Most of the milling during that time period was mainly being achieved from the beginning of 1943 to August, 1943, when the mill was suspended due to huge curtailment in labour being an issue at the mine site. From all ore milled the mill had process 107,608 tonnes of ore that mainly came from the underground workings and a small percentage had been taken from the stock pile. The total ore that was milled at a rate of 550 tonnes of ore had recovered 18,640.89 ounces of gold (Au), and 4,920.80 ounces of silver from this gold mine project. Prior to Production, the company had undergone a mill clean up in September, which resulted in 343.32 ounces of gold (Au) and 112.93 ounces of silver (Ag).
No milling was done in 1944, when the mine was being rapidly explored due to the curtailment that prevented the mine from gaining ore reserves within the underground workings at the time. Much of the exploratory work resulted in further diamond drilling and continuing the shaft to a depth of 1,136 feet, in which a new level was cut and stationed on the 1,100-foot horizon. Ore development at the time was also considered very favourable as new shoots of ore were discovered on the mines 800-foot level at the time. It's was also reported that good lengths and widths were associated with these new ore-shoots that had better grade ore than previously mined within the Jerome Gold Mine workings. At this point in time, the ore reserves within the Jerome Gold Project were increases to a total of 295,373 tonnes in which had an average head grade of 0.199 ounces of gold (Au) per tonne of ore mined. Diamond drilling at the time had amounted to 7 surface holes, totalling 1,495 feet, and 143 underground holes totalling 10,400 feet in length. Development at the time was also concentrated on five levels that were to included the 350, 500, 650, 800, and 1,100 foot sections of the Jerome Gold Mine Project.

Mining operations by the Jerome Gold Mines would continue from January, until June,30, 1945. Most of the development and exploration work had also disclosed new favourable ore locations within the mine working that needed more follow up and development work but could not be done due the necessary workforce need in order to complete this. These new ore-locations did not seem to have any importants to being economical at the time which resulted in suspending mining operations at the Jerome Gold Mine Property for the time being. Other plans were also aimed at restarting mining operations once the much needed labour was succeeded to commence underground development work and underground explorations at a much larger scale, in which would start milling operations back up at full capacity. All the machinery was rather taken out at this point in time as the underground workings were allowed to flood, but the buildings were still being maintained and a watchmen was place on site.

The mining town of Ramsey that was also a railway Station on the Canadian Pacific Railway Line was first establish within the operating year of 1942, when the main truck road from the Mine to this Station was completed. A great amount of effort went into building the company's own town as the Jerome Gold Mines place a lot of contributions towards this town that's now a ghost town. The Town of Ramsey was rather a thriving community in the northern part of Ontario as it had a lot of different accommodations that were build by the Jerome Gold Mines, Limited. Some of the things that had become build during that very year had included a community club house with a theater, a 2 storey bunk-house with chlorinating equipment, and Three dwelling houses were also altered and modernized for the use of mine foremans.
In 1986, the Jerome Gold Mining Corporation and Muscocho Exploration, Limited had rather made an agreement with the E. B Eddy Forest products, Limited, An option to purchase the Jerome Gold Mine. it was at this time that theJerome Gold Mining
Corporation had paid $100,000 towards optioning the property and placing $25,000 monthly that would be detucted from the acquisition price of $2,500,000. It was at this time when Muscocho Exploration, Limited had earned 50% of the interest in Jerom Mining Corporations interest in this option, and was currently the exploration operator. Later within 1987, the Jerome Gold Mining Corporation had announced to start a major development exploration program on the past producing Jerome Gold Mine. Previous development and exploratory work had rather become active from 1938 to 1945, and mill was done from 1941 to 1943, at a rate of 550 tonnes of ore per day. Within three years of operating the mill had rather process 303,906.9 tonnes of ore that recovered 56,878 ounces of gold (Au) and 15,104 ounces of (Ag). The current state ore reserves at this time were now marked at 335,000 tonnes of ore that had an average recovery grade of 0.19 ounces of gold (Au) per tonne of minable ore above the 200 m level.
Major construction at the time was also ongoing at the mine site when the two companies had started developing at camp for accommodation purposes at the Jerome Gold Mine Site in 1987. The two companies rather had also made joint partnership agreements of equal basis. It was also at this point in time when dewatering the shaft to the 347 m horizon was started, and Surface diamond drilling on the Main and South Zones would also take places that included bulk sampling of the already defined ore blocks in the main zone, and developing assess to the South Zone from existing workings were planned for 1988. Much of the objection of this three phase program was also mainly being aimed at increasing the known ore reserves within the mine working of 680,388.5 tonnes, grading 6.5 g/t gold.(Au).
Further exploratory development was now commencing when the dewatering of the shaft was taking place in the later part of 1987, and was aimed to be dewatered down to the third mining level at 500-feet below the surface. This second wave of development work was clearly about to start when the Warehouse-garage was refurbished, a head-frame, hoist-house, dry-house and the rehabilitation of the underground workings were started. It was within the later part of January, 1988, when the first level at 61 m of the Jerome Gold Mine had been accessed for further assessment work. Most of the dewatering had rather continued up until May, 1988, when a blockage was encountered at 125 m below the collar of the Jerome Mine Shaft. Much of the evolution of the second level at 106.7 m, and clearing the shaft was mainly delayed up until August of that very year. Plans at the were mainly aimed a removing the obstruction that had caused a stop to dewatering of the Jerome Gold Mine Shaft, and had proceeded to the third level at 152.4 m, which water levels had been maintained to a depth of 167.6 m.
Exploratory development work had rather continued onward when the East Drift on the 152.4 level was slashed out 2.5 m wide by 2.75 m high for a distance of 298.7 m Plans were also being made towards driving a southward crosscut for 130 m on the same level at a distance of 305 m to the east of the shaft in order to access the South Zone. Mostly the development planing on the 152.4 m level was aimed at continuing a rapid exploration program that would consist of 460 m of exploratory lateral development. Other machinery was also being used in part of the aggressive exploration plan by the Jerome Mining Corporation, and Muscocho Exploration, Limited, and had included a 5 ton truck that was currently in use on the 152.r m level. Access at the time was gained to the 61 m and 106.7 m levels that was undergoing further exploratory work, geological mapping, and surveying was completed at the time. On the 106.7 m level, the company had encountered open stopes and poor ground conditions that rather had made the second level inaccessible at the time. Much of the east drift on the 61 m level was reported to had been in fairly good conditions for further exploratory work that was to be completed on this level. This drift at the time, was also cleaned out, washed, and geologically mapped in regards to better understanding the nature of this ore deposit.
Early in 1988, the two companies had rather progress with this project when a surface diamond drilling program was started at the Jerome Gold Mine Site. Phase one of this drilling program had rather been carried out between late 1987, and the early part of July, 1988, including 65 holes, plus 3 extension holes, totalling 14,020.5 m. Much of the program was aimed at testing the South Zone that's situated 125 m from the main ore zone, to a vertical depth of 160 m over a 305 m strike length. Several holes were extended northward, and had intersected the main zone below the 160 m level. Preliminary drilling that was done on the South Zone had indicated ore reserves of 114,595.6 at an average grade of 6.0 g/t gold. For the most part, The south zone is rather described to be open to the west and below the 160 m level of the historical Jerome Gold Mine Site. Phase 2 of the drilling program had rather totalled 1,767.8 m in three deep holes, and was mainly carried out to test the downplunge continuity of the main zone. Other plans were also made to continue this exploration program from underground drill stations on the 152 m level South Zone Drift. Later in 198i, the company also would start phase 3 of the drilling program that totalled 6,111 m from the surface in order to test different areas of the main zone workings. The program within this time was designed to confirm existing reserves, define and upgrade areas of possible ore reserves, and to better understand the Jerome Gold Mine structure. By the earlier part of December, 14 holes, totalling 2,725 m had been completed, and was expected to confirm new mineralized areas in 1989.
At about 150 m east of the shaft, drilling had intersected a well developed mineralized zone that was approximately 25 m north of the existing development drifts, between the fourth level at 198.1 m and the fifth level at 243.8 m. The geologist of the company had also suggested that the new zone is actually the main zone at depth, and development drifting on fourth and fifth levels may had actually followed a splay of the main zone. If this is the case, then the main zone was reported to have been dipping more steeply at depth. Recently the company would also initiate under ground diamond drilling program from the 152.4 m level that was continuing to define this zone
Much of the exploration program at the time was rather consisted through 1987 to 1989, when had become discontinued for the time being and the mine was place on care and maintenance by the end of 1989, and the workings were allowed to flood. Underground development on the 152 m level was also officially completed in 1989, in which the East Drift was slashed out 305 m from the shaft to accommodate the much needed reckless equipment. From that point, a crosscut was then driven south for 107 m to access the South Zone. The total amount of drifting on the South Zone workings at the time had rather totalled 146, of which 133 m was in mineralization. On both, the east and west ends mineralization was truncated by faults, and a chip sample of drift faces on the West Drift average 9.1 g/t gold (Au) across 1.8 m for the 75 m long exposure. Much samples for the same 72 m length had also average 4.1 g/t gold (Au) across the development drift for a width of 2.5 m.
An underground diamond drilling program totalling 4000 m in 24 holes was completed in 1989, in which drilling from the South Zone on setups on the main zone drift totalled 1121 m in seven holes. Two holes totalling 64m were also drilled from the main zone in order to conduct exploratory work on the North Main Zone which was first intersected in the drilling program. A total of 2512 m in twelve holes was completed from setups on the South Zone drift to test the down dip and downplunge of the main zone Three exploratory holes, totalling 305 m were also drilled from various setups on the 153 m level, and in addition to This, 40 short holes, totalling 885 m were completed with the use of a Bazoka Drill to test mineralization in the walls of the Main Zone.
A three phase surface diamond drilling program carried out between 1987 to 1989, totalled 23,889 m in 93 holes. The surface drilling program on the South Zone had consisted of 64 holes, and the Main Zone and the East and West extensions of the main zone structures had been traced by diamond drilling for 2750 m along a trend in 29 holes. Ord reserves that were calculated from this massive exploration program had rather indicated estimations of 523,894 tonnes at an average grade of 6.5 g/t gold (Au).
it was in 2008, when Augen Gold Corp had taken over the property that was previously staked by management of the company, and had raised 16 million towards conducting further exploratory work on the Jerome Gold Mine Property. Augen Gold at the time had rather directed a portion of this capital towards conducting an aggressive exploration program on the Jerome Gold Property that includes drilling and modeling in order to extend the mineralized zone and to increase reserves.
Exploratory work was rather being done at much rapid pace as Augen Gold Corp was on route with exploratory work at the historical Jerome Gold Mine and other veins in the area that were reportedly opened along strike and at depth. Much of the geological series were also closely related to the prolific gold camps of Timmins-Kirkland Lake within the Abitibi Greenstone Belt that hosts many productive mines. The company had rather conducted plans in searching for three types of deposits on the Jerome Gold Mine Property that includes Quartz Archean Carbonated Lode Gold, information hosted gold, and vocanogenic massive sulphides. Augen Gold had rather completed a major diamond drilling program of 10,500 M in 21 holes in order to obtain test mineralization down dip and along strike. The first two holes that were done had mainly been aimed at proving historical grades. Hole No. 2 rather returned 8.35 m of 15 grams of gold per tonne, and 0.08% Molybdenum from 134 m depth, including 3.6 m of 31 grams gold and 0.14% Molybdenum. The same hole had also returned 4 m 7.9 grams gold per tonne and 0.076% Molybdenum from 165 m, including 1 m of 23 grams gold tonne and 0.078% Molybdenum over 168 m. Hole No. 1 had also returned 0.42 m of 71 grams gold per tonne and 17% Molybdenum from 165 m. other exploratory work was aimed at testing the mineralization at depth which had proved to continue at depth but was fairly low in grade. Historical data also indicates that there are numerous lower grade gold values at depth, but the east portion of the mine workings cotains some of the higher grade gold assays that indicated a new zone of 0.19 ounces of gold (Au) from the east. (Conclusions made by OntarioExplorations101). Most of the mining at the time of closing down due to labour shortage issues had rather stop on the eastern section of the mine workings when the mine was allowed to flood in with water. Much of the drilling by Augen Gold Corp had additionally traced the mineralization of the main zone for a length of 1km west of the Jerome Mine Shaft. Exploratory work on this section had also revealed a new gold bearing sulphide zone that was discovered south of the Southern zone of the mine. Gold at lower depths rather indicated 1.4 grams of gold, and 0.047% Molybdenum down to 600 m.
Jerome Gold Mine Geology and Economic Potential
For the most part the regional rock within the area is made up of greywack with some conglomerates, which the latter is very prominent in the Southern part of the Jerome Gold Mine Property. The sediments that are related to this property have also been extensively intruded by dike and bodies of porphyry, in which contain feldspar porphyry, and is less altered that's largely found southwest of the shaft in outcrops. The feldspar porphyry is also determined to be highly carbonitized and altered so that it weather into a grey color. Much of the sediments in vicinity of this intrusion have also been altered, and porpyritized so much that the distinction between them, and the porphyry is rather difficult to make. A small amount of lamprophyre also occurs in outcrops, with the best exposure being on a small island just north of what is commonly known as Jerome Point by many who know the history of this project. Some diabase dikes in relationship to the Cobalt Embayment are known to also occur at the southeastern part of the property near the Osway and Huffman Boundary, and had also been intersection in diamond drilling from historical intersections on other part of the property. A study performed by OntarioExplorations101 on the map of previous working indicates that the vein zone rather lies near the contact of the sediments, and along the porphyry. Much of the porphyry rather lies near the surface of the West end of the workings, but had been determined to have pitched irregularly east to a depth of more than 1,000 feet near the east end, that's judge from the map of the workings. The eastern end of this mine it was also determined that the vein had rather strike N 050° W, and curved gradually to strike N. 080° W. On the West end, with an average dip of 072° N. For the most part, there was also a gradual arc in the shear zone that maybe importance in the structural control of the emplacement of the ore that appears to be faulted by Feldspar Porphyry. Some of the fractures and stringer zones were also noted to diverge tangentially towards the east and west of the center of the arc in the main-vein zone. During development of the mine their was a number of faults encountered that have a resemblance of the Kirkland Abitibi Greenstone Belt that's apart of the Timiskaming Assemblage. One of these faults was reported to have strike N. 010° to 025° W, and had dip east at angles of 020° to 040°. These are rather known as frustfaults that hace a predominant vertical movement, which is shown by striae and mullion structure, and right hand horizontal displacements from 1 to 50 feet. The faults on the second set apparently strike N. 065° to 075° W, usually at small angles to the strike of the vein zone, and had dip nearly vertical. These rather intersect the thrustplane that i have already describe, and have their own displacement from 1 to 30 feet. The horizontal shift of these faults is right handed, I.e. north side west, in which tension fractures associated with these faults strike N. 045° to 065° E and dip at 075° W. Much of the tension fractures probably cut across earlier vein material and also thrust faults, which are filled with milky quartz carrying course Pyrite, tetrahedrite, and native gold. It's quite obvious that the least one stage of gold mineralization is later than the post vein thrust faults. This was rather a further borne out by the assay plans, which show a concentration of higher grade gold under the east dipping faults. These foremost hydrothermal solutions had probably been active along the thrust fault planes is shown by the bleached wall rock and the development of sericite and tourmaline for 3 feet or more on either side. The mineralized zone is rather very complex in structure as those of the Kirkland Lake Mines that are also associated with a number of faults planes that displace the veins by up to 100 feet in some cases.
The Jerome Gold Mine rather comprises of a cherty zone of bluish-grey quartz from 3 to 4 feet wide on the northwall, in which a central section of classy quartz and white carbonates appears, and on the south wall a discontinuous vein in place consisting of stringers and blushish quartz. The main vein was very persistent but had also varied in width and became locally interrupted, in which there are local thick sections, some of which are wider portions of the main vein, while other appear to be more ore less isolated pods. In addition to the lenticular nature, which is a primary future of the vein structure, the mineralized zone is further broken up by fault sections which make it a complex geology structure to work with. The vein is rather well exposed on the surface but only in one place, a small pit to the northeast of an open cut, which is located at about 250 feet northeast of the shaft. On the southeast wall of this pit, a detailed section from the northeast to southwest included to feet of schist with pods of solidified mineral, a 2 1/2 foot lens of silicifide country rock, 8 inches of schist, a horizontsl lens of bluish-grey, cherty quartz with carbonates, 12 inches of schist with lens of quartz, 20 to 30 inches of cherty bue-grey quartz, which contain inclusions of country rock, and cut by carbonated veinlets, both quartz and carbonte being intersected by more glassy quartz. The total wide of the mineralization exposed is rather 30 feet wide within this pit and the surface. Between this and the open cut southeast, the mineralized zone is presented by silicified, carbonatize, greywacke. The sediments and feldspar porphyry is rather red in colour due to alterations, which are widely distributed in the area. Much of the glassy quartz are rather formerly mineralized with metalics, which can not be determined upon visual examination, and is known for carrying most of the value. Examinations done on the surface had also disclosed Pyrite with very little gold values, and exceeding fine grained silvery metallic, cobalt. The blue color is also caused by the metamorphism that is widely distributed by these metallics. Chalcopyrite, tetrahedrite, Galena, sphalerite, and molybdenite are also distributed, in which visible gold is fairly rare on this property. The feldspar porphyry quartz had rather also been formed by the silicification of the country rock, which chalcopyrite and tourmaline were noted in the glassy quartz. Gold values within the glassy quartz are also said to give off more lower grade assays than that obtained in the more darker coloured quartz. According to Brown the vein material is rather known to also extend for widths of 15 to 75 feet in places, and continuous ore shoots had been for lengths of 3,000 feet, in which not all mineralization constitutes ore. Most of the ore shoots in this zone had shown a steep rake to the west and are found to bottom in a zone of quartz and carbonate, which carries no values. It's also stated that the values rather extend at depth at the eastern portion that are associated with the feldspar porphyry that acts as a fault plane in the mine workings, as values don't seem to extend extend below the bottom of the porphyry.
Ore reserves from the Mine were also officially estimated in 1945, to contain 335,000 tonnes of ore, averaging 0.19 ounces of gold (Au) per tonne of ore mined after dilution. Milling at the Jerome Gold Mine began on August, 28, 1941, and had become suspended in 1945, due to a labour shortage that the company was face with in developing this mine a much larger scale. Within three years of being active the mill had rather process a lot of ore that amounted to 335,000 tonnes and would obtained a bullion values of $2,189,822 in gold and $5,829 in silver recovery. Other exploratory work had also indicated another mineralized zone to about 400 feet south of the main vein by surface work and diamond drilling. It was also determined that this mineralization was located along the feldspar porphyry sediments, and had been indicated by drilling for a length of 1,400 feet, and has a maximum width of 60 feet. More so the north wall of this zone is strongly known to be only exposed, in which is highly carbonated, silicified, sheared, and locally brecciated. Stringers of glassy quartz and tourmaline, along with chalcopyrite cut this zone where carbonate stringers are also present. This prospect at the time was commonly known as the Skye Prospect which extends for more a mile south of the main ore-body at Peepeesways Lakes, and for about a mile west of Ramsey Road. This mineralized contact is mainly found to the east of the main zone where the Jerome Gold Mine was developed, and the south wall mainly consists of massive amphibolite and Greenstone. The shear zone on the Skye Prospect mainly extends for half a mile to the west and east. Grab samples of silicified, well mineralized material from this zone gave of 0.02 to 0.08 ounces of GOLD (Au) per tonne. Two chip samples were also taken from the east of the workings that gave off 0.03 ounces over 6 feet and 0.40 ounces of gold (Au) for over 2 feet.
The Jerome Gold Mine is rather underlain by an meta-arkose, and meta conglomerate that have been intruded by the Jerome Porphyre. The Porphyre portion includes trondhjemite, Granodiorite, and also syenite varieties, with quartz and feldspar-phenocryst. The Contact between the Jerome Porphyry and metasediments is also strongly sheared and very altered over width of some 120 m. Two mineralized veins, known as the Main Zone and the South Zone, occur along the edge of the shear zone and are separated by it.
Orogeny and Time Period of the Swayze Series Rocks.
The orogeny time period is rather put together by OntarioExplorations101, and is provided towards exploratory work in the region in knowing what much of the rocks and minerals associated with formations constitute in the general area. In relation, the Jerome Gold Mine is largely apart of this economic belt that resembles to the prolific gold area known as the Kirkland Lake, and the Abitibi Greenstone Belt. Many of the fault planes are related to this area that makes up a much complex geological setting to work in determining gold potential Targets. Most of the work by Augen Gold Corp was mainly aimed at exploring Quartz Carbonated Archean Gold, Iron Formation Lode Gold, and Volcanogenic Massive Sulphides, but had left out the prolific shear zone that extends for quite a distance.
The Swayze Series rather forms the southern part of the Raney-newton Assemblage and consists of conglomerate, iron formation, turbiditic wacke, arkose, and chert in associations of feldspar porphyry that in many cases acts as a fault plane, and interlayered by felsic Metalvolcanic rocks. The main minerals that are associated with the Swayze Series is known to consist of Au, Ag, Co, Cu, REE, Ni, and Mo. There is also the possibly for Basemetal and polymetalic deposits that maybe be associated within this geological Subprovince that hosts some of Ontario Gold Occurence like the Cote Gold Project, the Herrick Mine, the Ronda Gold Mine, The Jerome Gold Mine, the Shining Tree Gold Mine, and many of there gold properties that acted as prospect sites from 1900 to the 1960's. Many of them are also currently under explorations by various companies who find the potential in economical gold discoveries. The area is also largely made up of many different assemblages that characterize the geological structure in hosting many different type of formation mentioned below, and the mineral potential this area has.
In the western central part of the Raney-newton Newton Assamlage, the metasedimentary rocks face south, but are overturned and dip steeply from 060° to 080° to the north. Conglomerate Pebbles consist of felsic, porphyrs, chert, and mafic volcanic rocks, along with Granodiorite. The Swayze Series is rather interlayered with metavolcanic rocks along the Southern part of the Raney-Newton Assemblage. These metavolcanics fragment types rather dominate in the metasedimentary rocks. It's also observed that these are consistent with a volcanic and clastic origin for the Swayze Series, which appears to be stratigraphically equivalent to the felsic metavolcanic rocks of the Raney-Newton Assemblage. The age of these rocks are known to be determined to range in two different ways, the first is related to U-Pb that dates to 2697 million years ago, and the second is related to tholeiitic and Komatitite flows that are 2826 million years old.
