Osisko released an updated Preliminary Economic Assessment (PEA) in April 2021 focusing on the Windfall gold deposit. The PEA develops the Windfall deposit as an underground dual ramp-access mine with a 3.1kt/d carbon-in-leach (CIL) circuit processing plant to produce gold with silver as a by-product. In November 2022, a Feasibility Study was published for the operation, which targeted a production rate of 3.4kt/d. The life of mine of the project is 11 years and is expected to produce a total of 2.9Moz of payable gold and 1.3.7Moz of payable silver. Initial project capex is estimated at CAD$789 million.
