There are several old pits. and trenches that exposed irregular quartz carbonate along the Eastern Base of Mount Ferguson. Each of the pits that were put down are estimated to have been developed at about 60 year ago by Father Paradis of Porcupine. The showings had rather lied in a small valley that run northeasterly in which joins a large northwest trending valley that the Coppersand Mine is situated in. This foremost large valley also lies within the eastern and lower contact of the diabase mass that forms Mount Ferguson. Much of the diabase mass is rather coarse grained, granophyric, and has the structure of a sill. Its also under lying by argillite, greywacke and conglomerate of the Gowganda formation. The lower contact of this sill contains quartz carbonated veining that are associated with the sill, and the adjacent argillite. There also three main showings that are situated at about 1/4 of mile South of Coppersand Lake. At the beggining of the south, there is a flat lying quartz carbonated vein containing pyrite, chalcopyrite, pyrrhotite, and galena in stringers, and patches. The vein observed lies within the diabase, which is near its lower contact, and has inclusions of sheared diabase, and argillite. Diamond drill core from present exploratory work shows that it ranges in thickness from 10 to 30 feet, and the mineralization is shortly distributed. Assaying that was done on one of the trenches in 1960, had showed 0.02 ounces of Au, 1.42% Cu, and traces of Co, Ni, and Ag over a length of 100 feet. To the north of the Diabase Contact, there is also another quartz carbonated vein. It rather has a rolling strike that dips 020 degrees to the west, and south west. The quartz-carbonated vein also ranges in thickness from 6 inches to 6 feet, and is well mineralized at the base with chalcopyrite. Samples that were taken by Derosier had given off 9.22% Cu, 0.13% Ni, 0.09% Co, 8.56 ounces of Ag. Another quartz veins is also situated 200 feet north, on the west slope of the valley, and 100 feet below the diabase contact. This veins also cuts interbedded conglomerate, and greywacke that has its own thickness of 8 feet, which strikes N 030 Degrees W, and dips at about 010 to 040 degrees N.E. Further so, this vein is exposed in a northeast trending cliff where chalcopyrite is concentrated in patches.
Another huge change was shortly after made when another prospector known as D. Derosier had staked this property in 1957. It was during this time when a road was constructed to a newly developed cabin from Sandy Inlet via Coppersand Lake. Nevertheless a drill road and a trail became establish through the bush line at Sandy Inlet in order provide easier transportation to the mining site. By this time the company would undergo its own exploratory procedures when some trenching became conducted. In addition the company would also drill one short vertical diamond drill hole to determine what was hidden beneath the ground. Grab Samples taken by Derosier had given the following results upon assay. Copper was found to average 1.36-10%, Silver was assayed up to 5.32 ounces per a ton, and another assay of lead was recovered and had graded 3.95%.
The prospector would later option three mining claims around Coppersand Lake to the Mayer Mining Company, Limited, in 1960. Further explorations were continued when the company drilled 6 diamond drill holes on a flat lying quartz vein that wasn't located to far from Coppersand Lake. Logs of another six diamond drill holes would also be summited in 1964 for assessment credit. These exploratory zones had soon indicated a thick quartz-carbonated vein that consisted of Chalcopyrite, and Pyrite. But with not enough encouraging results the company also decided to fold, and the mine once again became abandoned.
In 1965 the mine was undergoing new staking's when the Keevil Mining Group Limited had taken over this production. A small exploration phase was known to have been conducted within this time period that consisted of a Ground Geophysics Survey. It was also reported that the company was undergoing assessment phases on two of the many claims that make this mining zone. These historical claims became registered under T-55445 and T55446. Much of this mining zone was also reported to have been optioned to the Keevil Mining Group Limited by the previous owner who was Mr. Derosier. Generally this whole entire staking was establish to further explore the copper showing within this geological area. Exploration work consisted of line cutting, and geophysical surveys that became conducted within the period of October, 20th to December,2nd, 1965. A grid totalling approximately three miles of line was cut from a base line to the north of the property. Lines within this sections became strongly considered to have been cut at 200 foot intervals to the east of the base line. Mining within the Coppersand property was never a productive project as the Keevil Mining Group Limited. had also abandoned mining operations at the Coppersand Mine by 1966.
By 1969, the whole entire prospecting ground was staked by another prospector who was identified as A. Hardie. He immediately commence mining operation when he started to extend the old mine workings, and had additionally blasted some new pits. It was during this period that he would also additionally incorporated his own company that became recognized as the Gunnex Limited. In addition his very own company would further undergo exploration procedures when 20 diamond drill holes, totalling 2,500 feet of core sample became driven within the rock. Further land stripping procedures would also be completed in order to determine what was hidden beneath the ground. The Gunnex Limited would also ship their first 300 ton bulk sample for further assaying procedures. These indications from the samples had given assaying grades of a trace to 0.20 ounces of gold per a ton of rock, silver was assay at 0.06 to 6.25 ounces per a ton, 0.32 to 22.5% Copper, 0.11 to 0.57% Nickel, and 0.06% Cobalt. With not enough encouraging results he to decided to abandoned mining operations at the former Coppersand Mine Exploration Project.
