During this period, Tiblemont Consolidated built a camp with multiple permanent buildings, all of which are now gone. Nearly 3,350 linear meters of trenches were dug, as well as a three-compartment vertical shaft sunk to a depth of 155 meters. A 360-meter-long adit was also driven into the hillside at lake level, subsequently connected to the shaft at the 100-meter level. Underground development extends to 1,800 meters at the 360 and 485-meter levels. A 5-ton mill was also in operation. Documents from that time indicate several gold-bearing zones located near the surface that could be mined using open-pit methods. A resource estimate, not compliant with Regulation 43-101, indicates 391,000 tons at a grade of approximately 2.8 g/t at a depth of just under 60 meters (GM41028). Multiple exploration programs have been carried out in previous years. Notably, in 1982, SOQUEM complet...
