Summary
The proponent, Osisko Mining Inc., would like to operate a borrow pit as part of the exploration activities at the Windfall mine, notably for the construction of accumulation ponds and storage pads. The proposed borrow pit is located near Windfall mine, for which the proponent is currently preparing its impact study.
A certificate of exemption was issued on May 6, 2022 for the bulk sampling of the Caribou and Lynx-4 zones at the Windfall mine. That project included the expansion of the waste rock pile, construction of a stockpile for mineralized material, and construction of 4 new ponds and a water treatment plant. The current borrow pit project was not included in the original project because the proponent believed it had sufficient reserves of granular materials to carry out the work. However, since the issuance of the certificate of exemption, the proponent has learned that the exploration work will require more granular materials than anticipated.
