Osisko Mining Inc. provided new analytical results from the ongoing expansion and definition drill program at its 100% owned Windfall gold project located in the Abitibi greenstone belt, Urban Township, Eeyou Istchee James Bay, Québec. Drilling is currently focused on the Lynx deposit. Selected high-grade intercepts from the new results include: 108 g/t Au over 10.5 metres in OSK-W-20- 2256-W7; 21.7 g/t Au over 11.3 metres in OSK-W-20-2271-W3; 76.7 g/t Au over 3.0 metres in OSK- W-20-2377; 30.9 g/t Au over 4.5 metres in OSK-W-20-2292-W4; 35.1 g/t Au over 2.8 metres in OSK- W-20-2325; and 36.5 g/t Au over 2.1 metres in OSK-W-20-2283-W3. Mineralization occurs as grey to translucent quartz-carbonate-pyrite-tourmaline veins and pyrite replacement zones and stockworks. The vein-type is associated with haloes of pervasive sericite-pyrite ± silica alteration and contain sulphides (predominantly pyrite with minor amounts of chalcopyrite, sphalerite, galena, arsenopyrite, and pyrrhotite) and local visible gold. Replacement mineralization is associated with strong pervasive silica-sericite-ankerite ± tourmaline alteration and contains disseminated pyrite from trace to 80% with local visible gold. Pyrite stockworks can form envelopes that reach several tens of metres thick. Fuchsite alteration is common and is spatially constrained to near the gabbros. Mineralization occurs at or near geological contacts between felsic porphyritic or fragmental intrusions and the host rhyolites or gabbros and locally can be hosted along the gabbro-rhyolite contact.
