The inferred category contains 3.3 million oz. in 12.3 million tonnes grading 8.4 g/t gold. About half of these ounces occur in the Lynx deposits.
To calculate the resource estimate, Osisko used a gold price of $1,600, a recovery rate of 93%, and a 3.5 g/t gold cut-off grade.
The new resource estimate convers the Lynx, Underdog, Main, and Triple 8 deposits to a depth of 1,200 metres from surface. A bulk sample has been taken from the Lynx 600 zone. When milling is complete in early-October, results will indicate a higher grade than indicated by drilling. This was the case when two prior bulk samples were processed and returned grades that were 26% and 89% higher than anticipated.
“With this final MRE update prior to our pending feasibility study, we have met and exceeded our objectives for the Windfall drill program: a robust measured and indicated resource of over 4.0 million oz. with an average grade of over 10 g/t gold, said Osisko CEO John Burzynski in a statement.
“The scale of Windfall and the deposit grade has steadily increased since Osisko’s discovery of Lynx in late 2016. Lynx now represents almost two-thirds (65%) of the total gold in the MRE, and it continues to impress with a stand-alone total M&I resource of 3.1 M oz averaging 13.0 g/t Au,” he added.
