The potential for a high-grade iron oxide copper gold (IOCG) target on the Rocher Deboule property is documented in the 2002 British Columbia Ministry of Energy and Mines, Geological Survey Branch publication “Fe-Oxide Cu-Au Deposit Potential”. The deep seated structural setting of the Rocher Deboule occurrence combined with a geochemical signature similar to other IOCG deposits increases the potential for an IOCG–type high grade and tonnage resource at depth. This may be suitable for a larger scale development scenario.
The British Columbia Department of Mines and Petroleum Resources in its Bulletin No. 43, “Geology of the Rocher Deboule Range by A. Sutherland Brown (1960)” identified that the Rocher Deboule property contains high grade gold/silver/copper/cobalt/ molybdenum veins that have been mined in the past.
For example, from page 60 of this Bulletin No. 43, the recorded production of the Rocher Deboule Mine is as follows:
