Project summary

With this project, Troilus Gold Corp. wants to proceed with the dewatering of the J-4 and F-87 pits of the old Troilus mine, which has been under restoration since 2011. The dewatering would allow access to the deep deposit of the old mine in order to continue work exploration from the floors of the pits. The gold and copper deposit shows continuity at depth and to the north, in the axis of the J-4 and F-87 pits. The drilling carried out in 2018 seems to demonstrate the existing mining potential still present. According to certain local arrangements to be made, the water from the pits would be discharged into the so-called “sans nom” stream located west of these same pits.
