Greywacke North Deposit 2021 Historical Technical Report
The Greywacke North Deposit has a combined open pit and underground Historical Indicated Mineral Resource of 645,000 t averaging 4.90 g/t Au for 101,000 in situ ounces of gold (600,000 t at 4.89 g/t Au, and 45,000t at 5.03 g/t Au, respectively), plus a combined open pit and underground Historical Inferred Mineral Resource of 410,000 t averaging 4.12 g/t Au for 54,000 in situ ounces of gold (35,000 t at 1.97 g/t Au, and 375,000 t at 4.33 g/t Au, respectively). Recent metallurgical work showed that a combined gravity and cyanide leach process would expect to recover 94% of the gold. The Historical Indicated and Inferred Mineral Resources were estimated using open pit and underground cut-off grades of 0.65 g/t Au and 1.75 g/t Au, respectively (Godden, S, Thomas, D. Tupper, D. Technical Report on the Mineral Resource Updates, North Lake Deposit and Greywacke North Deposit, La Ronge Gold Belt, Saskatchewan, Canada.; effective date December 1, 2021). The Historical Technical Report regarding the updated Historical Mineral Resource estimate was filed on SEDAR January 12, 2022.
