Osisko Mining Inc. provided new analytical results from the ongoing drill program at its 100% owned Windfall gold project located in the Abitibi greenstone belt, Urban Township, Eeyou Istchee James Bay, Québec. The intercepts located outside the February 2020 mineral resource estimate wireframes . These intercepts either expand the resource wireframes or are located in a defined zone/corridor but not yet correlated to a specific wireframe. Significant new analytical results are presented below and include 80 intercepts in 27 drill holes and 22 wedges. Selected high-grade intercepts from the new results include: 344 g/t Au over 2.2 metres in OSK-W-20- 2313-W2; 114 g/t Au over 2.6 metres in OSK-W-20-2280-W5; 90.2 g/t Au over 2.0 metres in WST-20- 0380; 74.2 g/t Au over 2.2 metres in OSK-W-19-1949-W3; and 26.7 g/t Au over 7.0 metres in WST- 20-0078. Lynx Zone: 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. Triple Lynx: Mineralization in the Triple Lynx zone is vein-type, quartz-carbonate-pyrite-tourmaline veins, associated with pervasive sericite-pyrite ± silica alteration and contain sulphides similar to the main Lynx Zone, pyrite dominated with minor other sulphides, ranging from trace to up to 70% locally, and local visible gold. Locally fuchsite is present when proximal to the gabbros. Mineralization is hosted in or at the contacts of felsic porphyritic dikes with rhyolites (locally bleached) or gabbros.
