Osisko Mining Inc. on May 14 announced an initial resource estimate for its Windfall gold project in Quebec.
At a cutoff of 3.0 g/t of gold, the property hosts 601,000 ounces of gold within 2.4 million tonnes at 7.85 g/t of gold in the indicated category, and 2.3 million ounces within 10.6 million tonnes at 6.70 g/t of gold in the inferred category.
The estimate is based on 596,733 meters of drilling in 1,453 holes completed by previous operators on the project since 1997, and includes 413,692 meters in 812 new holes completed by Osisko from October 2015 to March. An 800,000-meter drill program is ongoing to expand and explore the deposit.
Osisko Mining President and CEO John Burzynski said the company intends to incorporate its Windfall and Osborne-Bell deposits into a single preliminary economic assessment, scheduled for early in the third quarter, which will feature a blended mining scenario.
