The Windfall Lake project is 100% owned by Osisko Mining Inc. The property comprises the Windfall Lake and Osborne-Bell mines, located approximately 115km and 35km respectively from the processing plant. The deposits will be mined over eight years with ore treated in a 3.2kt/d carbon-in-leach (CIL) circuit to produce gold with silver as a by-product. In 2018, a Preliminary Economic Assessment (PEA) was completed. Initial project capex was estimated at CAD$397 million. Average annual gold production is estimated at 218koz/a.
