The Cameron Lake Gold Deposit was first uncovered by extensive explorations that were carried out by Noranda Exploration Company, Limited. For the most part this had resulted in a gold mineralization that had showed significant widths of potential ore grades within the Cameron Lake Gold Property. Almost all explorations during this time period were being focus on the No. 2 zone which indicated profitable gold grades. These areas were considered to have not been fully determined on their continuation which resulted in several explorations. Even further explorations of the area had soon resulted in the discovery of the No. 1 and 2 showings. With this discovery made the company had soon conducted their own geophysical, and geological surveys. This exploration phase was also followed by a small to medium diamond drilling program that end up consisting of 42 surface holes, totalling a length of 6,992 feet. Diamond drilling within this time period was mainly focus on both showings that were conducted.
For the most part the No. 1 showing is known to be mainly made up of quartz carbonated vein that extends for a distance of 500 feet. The strike length is known to travel east-west and is west of Beggs Lake which resulted in several gold assays from the trenches. Diamond drilling beneath these trenches was reported to have been more discouraging.
Another showing known as the No. 2 zone is commonly describe as an altered shear zone or zones. Further explorations of this shear zone had resulted in a strike length of 400 feet that was in a northwest-southeast direction which dip northerly. Much of the zone was reported by Wolverton to have average a width of 9 feet, and had an indicated ore reserve at 37,500 tonnes of ore that had an average grade of 0.219 ounces of gold per a tonne of ore. More so this indication was taken from drilling which allowed the claims to lapse due to the limited tonnage in 1971.
1972- Property staked by Zahavy Mines, Limited.
Dimaond drilling by Zahavy Mines, Limited had consisted of 7 additional surface holes, totalling a length of 2,584 feet. Out of the 7 surface diamond drill holes the company reported that 3 of them had intersected several gold values in the westward extension of the No. 1 showing. Another four diamond drill holes had also became completed in the No. 2 showing. The property at the time had rather comprised of 28 unsurvey mining claims that were located in the Beggs Lake, Rowan Lake area of the Kenora Mining District. Explorations by this company results in a geophysical, electro magnetic, and magnetic survey. Much of the geology in the area is mainly stated to have comprised of basaltic, and andesitive, with massive lava, pillow lava, tuff, agglomerate, hornblende, and chlorite schist. The area was also made up of basic, and ultra basic igneous rocks that were mainly considered as a gabbroic composition. Even some areas within this property are known to also consist of granite, and related rocks. In several cases Metasediments, possibly greywacke is known to also occur throughout the general area. Other geological structures that are within this area are known to included major and minor faulting with abundant lineaments. More so this type of geological structure is known to have suggested that the base of a major fold structure is commonly known to possibly lie within the Begg Lake Claim Group. Other major minerals also had occurred throughout this area that had mainly consisted of gold, nickel, copper, and zinc formations.
This survey procedure resulted in a base line which was considered to have been laid, and had cut across the central part of this property. For the most part this geophysical survey was establish in an east-west direction for a distance of 8,800 feet. Picket line were reported to have also been turned of in a north-south direction at every 400 foot interval along the base line, in which were cut, and chained to the respect of the boundary line. Surveying procedures had resulted in the establishment of 30.5 miles of lines that were conducted at the time.
There was also a magnetometer survey that was conducted over the whole entire property that became establish by a Sharpes Fluxgate MF- 1 Magnetometer. Several readings were reported to have been taken between ever 50 to 100 feet along the picket lines. For the most part the magnetic data which was retrieved from this survey had resulted in anomalous trend through the west central part of this property. Other statements suggested that some of the magnetic futures had coincided with rust sheared outcrops in which known gold occurrences are known to exist. These particular shear areas are considered to be uncovered on claims 325241 and 325249. Most of the survey was also establish during the winter months which could not outline all the possible geological rock structures in the area.
1973 - Option made by Noranda Exploration Company, Limited from Zahavy Mines, Limited.
For the most part this was done in order to determine the westward extension of the No. 1 showing. Some more explorations would end up resulting in a diamond drilling program consisting of 9 holes, totalling 2,101 feet in length. Even with these explorations taking place Noranda Exploration Company, Limited were unable to confirm the westward extension of the No. 1 showing by three holes Some more explorations also occurred on the No. 2 showing at the time, which resulted in the completion of the remaining 6 diamond drill holes. .Diamond drilling within the No. 2 showing was stated to have confirmed to have extended to the northwest but did not add to the tonnage or grade it was looking for. With not enough encouraging results the option was dropped by Noranda, and Zahavy Mines, Limited. allow the claims to lapse.
1980 - Claims staked by Nuinsco Resources, Limited
During 1980, Nuinsco Resources had staked a total of 59 continuous mining claims that also occupied the Cameron Lake Gold property. In general being these claims were rather considered to have been staked by the company's prospectors who became identified as W. Morehouse, and D. Petrunks. As explorations commenced the company would additionally acquire a total of 40 more claims in 1980, and another4 in 1981. Explorations within this time period had resulted in a geological survey that was conducted over the whole entire property. This survey procedure resulted in the establishment of base lines, and L16W that were cut at 400 foot intervals and locally at 200 foot intervals. Other procedures resulted in a geological mapping survey that was establish on this property from May, 28 to July, 1, 1981. The whole entire survey procedure had additionally covered a total of 32 claims during this time period. .
1984 - Nuinsco Resources, Limited
Exploration by this company had continued to commence on it's Rowan and Cameron Lake Property during 1984. Prior to this exploration diamond drilling had consisted of 71 surface holes, totalling 65,819 feet in length. For the most part this diamond drilling phase had led to an increasing reserve estimation between 1.5 and 2 million tonnes grading between 0.15 to 0.20 ounces of gold per a ton. Even more diamond drilling was also done on Rowan Lake in 1983, which resulted in 12 holes, totalling a length of 5,122 feet. Almost all of this diamond drilling was reported to have commence on a prospect known as the Monte Cristo Prospect. Other exploration also occurred when induced pulverization survey took place on both properties. During this time period it was also stated that Lockwood Petroleum Incorporated had completed their expenditure commitment to Nuinsco Resource, Limited, in order to earn 50% of the Cameron Gold Property.
Nuinsco Resources, Limited had also held a total of 100% interest on 92 unpatented claims which surrounded 7 patented claims on the Monte Cristo Property. Most of this was also done under option agreement with Lakeport Gold Mines, Limited. in which the company would earn 80% interest in the 7 patented claims. It was during the winter season of 1984, when Nuinsco Resources, Limited had announce a winter drilling program that would be conducted on the Monte Cristo Gold Property. For the most part this was to test new anomalies that were uncovered by induced pulverization surveys over a strike length of more than 1 mile in the 400 foot wide shear zone. In addition to this exploration a new option agreement was worked out with Lockport in obtain 100% interest in the 7 patented claims. Diamond drilling over the winter season had consisted of sixteen surface hole which became put down on Rowan Lake, in which six were aimed at testing a new zone over a 500 foot strike length. Another zone known as the Victor Zone was rather situated at a distance of some 3,200 feet southwest of the Monte Cristo Gold Property. Company statements had stated that one of these holes had intersected a 26,6 foot section grading 0.371 ounces of gold per a tonne.
Drilling was commonly considered to have continued over the summer months on both property areas. With encouraging results Nuinsco Resources, Limited had decided to organize a public meeting with Dubenski Gold Mines, Limited. Much of this meeting was aimed at discussing a plan to build a road off of highway 71 south of Sioux Narrows to give access to both, the Cameron Lake, and Rowan Lake Properties, and the Dubenski Gold Mines, Limited property a Flint Lake, Most of all the drilling on the Cameron Lake Gold Property was aimed to determine the downward extension of the mineralized zones, and its continuation at depth. Further drilling of this area soon had increased the strike length by 3,000 feet. Geological mapping, and structural analysis around this discovery area had also shown that the gold is hosted in siliceous pyritic Barcia veins that are up to 100 feet long and 30 feet wide, grading 0.275 ounces of gold per a ton. Drilling at the Rowan Lake Gold Property was mainly aimed at exploring the newly discovered Victor Zone.
Another discovery that was located immediately north of the Monte Cristo Property was discovered by a 50/50 join venture between Bigstone Minerals, Limited, and Anglo Canadian Mining Corporation. Gold within this area was reported to have been uncovered in quartz veining which was in a shear zone parallel to that at the Monte Cristo Gold Prospect. Reports on this area had stated that two grab samples had assayed 26.88 and 20.24 ounces of gold per a tonne. Diamond drilling within this claim resulted in 11 surface holes, totalling a length of 1,100 feet, and in one of the holes a 3 foot section with visible gold assayed 0.121 ounces per a ton.
1987 - Nuinsco Resources, Limited - Joint Venture with Lockwood Petroleum, Inc. and Echo Bay Miens, Ltd.
In total diamond drilling the Cameron Lake Gold Property was reported to have received a total of 120,000 feet of diamond drilling. With good indications of testing the mineralized zone this company had decided to take commence development on the project. At the time it was stated that a ramp was driven for a distance of 2,330 feet, which resulted in 207 feet of remuck stations, 19,444 cubic diamond drill crosscuts, 177 feet of access crosscuts to the 365 ore zone, and 1,084 feet of ore zone drifting on the 365 foot level. Other development procedures were aimed at establishing a total of 40 feet of exploration raising. Ore reserves within the mine were considered to have been recalculated in 1987, to a depth of 1,200 feet. Much of this whole entire ore reserve estimation became recalculated by a firm of Trigg, Woollet, Olsen Consultant, Ltd. of Edmonton, Alberta, Canada. This recalculation had resulted in an ore reserve of 934,136 tonnes of ore that graded 0.175 ounces of gold, and had estimated a gold content of 163,901 troy ounces. There was also an indication of possible ore-reserves that could be obtained by systematic diamond drilling from underground. Development plans at the time were being aimed at continuing the ramp further in order to intersect the 685 foot level. Other major development will than include the construction of a ventilation raise, drifting on the 490 and 685 foot levels, raising in order to trace the continuity of the ore, and further sampling and diamond drilling. Some more underground diamond drill would than be conducted below the 685 foot level of this ramp.
A diamond drilling contract was also awarded to firm known as N. Morissette Canada Inc. on July, 12, 1987. It was by March, 2, 1987, when diamond drilling was officially commenced and had operated continuously. This was rather being done till the completion of the mine development contractor at the time. Diamond drilling was reported to have officially taken place on 365 foot level on July, 3, 1987. and was completed by August, 11, 1987. Another diamond drilling program was being conducted from the decline ramp in order to test ore reserves, and to guide the 365 foot level drift. The whole entire diamond drilling phase had consisted of 49 underground holes, totalling a length of 10,437 feet. Some more diamond drilling also commence on the 365 foot level drifts which consisted of 84 underground holes, totalling 8,800 feet in length. In order to test the continuity of the ore structure diamond drilling was reported to have been conducted at 25 foot intervals, and two shore holes became driven at 12.5 foot intervals to test interpretation. Diamond drilling within the Declined Ramp, and the 365 foot level had totalled a length of 19,237 feet of core.
1988 - Nuinsco Resources, Limited - Joint venture with Lockwood Petroleum, Inc. and Echo Bay Mines, Ltd.
Explorations of the Cameron Lake Deposit had soon resulted in much higher tonnage that totalled 930,000 tonnes of ore. Much of this ore was stated to have been disclosed to a depth of 1,200 feet, and had average 0.176 ounces in gold per a tonne of ore. This also resulted in an expanded diamond drilling and underground exploration program which included drifting and raising to the 685 foot level, and diamond drilling to the 1,600 foot level. Much of this was aimed a preparing the company finically in regards to capital, and operating costs for the mill, and milling complex. Accommodation within that time period was known to had included a 42 person camp, kitchen, maintenance building, and power house.
1983 - Union Carbide Exploration Corporation, Limited, -Joint Venture with Consolidated Professor Mines, Limited.
Further explorations would continue on what known as the Duport Mine Gold Property on Cameron Island, Shoal Lake. This resulted in diamond drilling, and a metallurgical testing of a 1,000 pound sample taken from the mine dump. Other company statements had stated that the mine will go under a development program in which a decline would be driven for distance of 2,000 feet from Stevenson's Island to the East zone at the 250 foot level. Another stage will than be commenced in order to test the main zone at deeper levels of this decline ramp.
1984 - Union Carbide Exploration Corporation Limited - Joint venture with Consolidated Professor mines, Limited.
Exploration by these two companies had taken place on what was known as the Duport Mine Gold Property on Cameron Island, Shoal Lake. Much of this agreements had allowed Carbide Exploration Corporation, Limited to earn 50% interest by spending 10,000,000 in stages. and by agreeing to put the property into production. Surface diamond drilling and Metallurgical testing of a 1,000 pound sample taken from the mine dump during 1983. With these results in it was stated that Union Carbide Exploration Corporation, Limited had announce a reserve estimation of 1,927,000 tonnes grading 0.30 ounce in gold per a tonne. The average width of this mining zone was reported to have been 9.75 feet to a depth of 1,150 feet, and had its own strike length of 2,400 feet. For the most part this strike length was reported to have been in two parallel zone that became determined as the Main Zone, and the East Zone. It was also during this time period when preliminary studies were being conducted in which statements state that if the property was to go into production, a 500 tonne per a day flotation mill is to be installed at a cost of $35 and $45 Million. Stage one of this development was reported to have been completed during the winter season on the East, and Main Zones, in which they were intersected at the 300 and 325 foot levels respectively. Development of this area had resulted in 900 feet of drifting on the East and Main Zone during 1984. This also resulted in a diamond drilling phase when a total of 3,400 feet of underground drilling was done, and bulk sample taken for metallurgical testing was completed. These tests soon indicated that the production rate of the mine will rather be at 180,000 tonnes of ore annually, in which will recover 45,000 ounces of gold per a year. Under terms of the joint venture agreement, Union Carbide Exploration Corporation, Limited had until October, 1985 to bring the property into production.
Much of stage two was reported to have commenced during the summer months, and was completed by November. This development phase had expanded the decline when it was driven further 1,325 feet in order to intersect the ore zones at the 440, and 530 foot levels. Almost all development that year resulted 802 feet, and 312 feet of drifting on each level. Even further explorations were commenced when the company completed a total length of 18,300 feet of diamond drilling.
Geology of the Cameron Lake Gold Deposit
One of the most economical gold deposits within the Kenora District of Ontario, Canada, is known as the Cameron Lake Gold Deposit. The whole entire geology of this area is known to be situated in the Archean Savant-Crow Lake Greenstone Belt. Much of this belt is commonly comprised of many volcanic rocks, and had more less abundant sedimentary rocks separating granitic bodies of various size. These volcanic rocks are commonly considered to occur in cycles, with both mafic, and felsic members. This area is also known to contain a number of faults with the major one being the Pipestone Cameron Fault in which passes the property 1 km southwest. Another property known as the Shoal Lake Deposit was also being prepared for production by the Consolidated Professors Miens, Ltd. More so the whole entire property is known to be underlain mainly by a series of pillowed and massive basaltic flows. Both of these varieties of basalts are considered to responded in the same way to shearing, alteration, and mineralization. One of the other major rock types that occupies this geological area is known to consist of a gabbro intrusive which occurs along the south side of this property. Generally the most important geological structure within this zone is commonly considered as the Cameron Lake Shear Zone. Much of this shear zone is stated to cross the property in a NW-SE direction, which is also roughly parallel to the Pipestone Cameron Lake Fault. Almost all the gold which was outline is known to also be associated within the alteration of the Cameron Lake Shear Zone. In general being the Cameron Lake Shear Zone is also determined to have a regular change in formation from 50 degrees N to 60-70 degree north at a depth of 400 feet for its entire length. Other changes to the shear zone occurred at 150 feet below the hinge line where the shear becomes extremely thick, over 100 feet in most cases. In the western part of this shear zone the mineralization is considered to occur at the widest part which is at a depth of 600 and 800 feet. Another shear known as the South Zone is considered to occur at about 200 feet south of the Cameron Lake Shear. Generally the south zone is known to be at the contact between the basic vocanics, and the Gabbro Body. All the ore within this mine is known to lie in continuous quartz lenses that are situated along a major shear zone system. Some of these vein systems are reported to be between 100 to 400 feet long and 3 to 40 feet wide in places. Diamond drilling on this section had indicated that this mineralization extends to a depth of 1,200 feet below the surface.
