Osisko Mining Inc announced new results from the ongoing exploration program at its 100% owned Windfall Lake gold project located in the Abitibi greenstone belt, Urban Township, Eeyou Istchee James Bay, Québec. Results from processing 5,500 tonnes mined from Zone 27 have exceeded expectations, returning an average grade of 8.53 gram per tonne Au. The bulk sample average grade is 26% higher than predicted by infill drilling on the resource block model. Mining of the bulk sample has successfully confirmed the presence of mineralization predicted in the resource model, and the analytical results have confirmed the visual mineralization encountered along the stope.

Highlights and full results are presented below:


Average grade of 8.53 gram per tonne Au for the bulk sample 26% higher than predicted in the 12.5 meter infill drilling block model

The sample contained 1,508 ounces Au and 1,450 ounces of Ag

Average Au recovery of 93.7% achieved using contract mill

5% of the gold recovered in the gravity concentrate

Mr John Burzynski, President and Chief Executive Officer, said that “We are very encouraged with the better than expected results from this first bulk sample completed from the Windfall deposit. The average grade is higher than predicted by our infill drilling, and falls within our of expectations for the overall grade of the deposit. This sampling work is helping to confirm continuity, grade, recoveries and the predictability of the mineralized zones at Windfall. We are looking forward to the second bulk test in the Lynx Zone, which we expect to collect over the summer and process in October.”
