Announcement summary: (Toronto, September 27, 2022) Osisko Mining Inc. (OSK:TSX. “Osisko” or the “Corporation”) is pleased to provide new exploration results from its 100% owned Windfall gold project located in the Abitibi greenstone belt, Urban Township, Eeyou Istchee James Bay, Québec. Hole OSK-22-1109-W2 targeted the projected down plunge extension of Lynx 4 at a vertical depth from surface of 1,670 metres. The hole successfully intercepted significant widths of high-grade gold mineralization, including 81.8 g/t Au over 3.5 metres (2.39 ounces per ton over 11.5 feet) and 22.3 g/t Au over 4.1 metres (0.65 ounces per ton over 13.4 feet). These intercepts confirm potential for a major down-plunge extension of the Lynx 4 high-grade zone, which could have significant implications for the future potential expansion of the Windfall deposit. The new intercepts are 625 metres (2,050 feet) down plunge from the nearest resource block (Lynx 4 wireframe 3449) included in the most recent Mineral Resource Estimate (“MRE”) for Windfall (see Windfall MRE (2022) (as defined herein). The technical report was filed on SEDAR ( under Osisko’s issuer profile on September 14, 2022). The new mineralization is typical of Lynx 4 wireframe 3449, including disseminated pyrite associated with strong pervasive silica alteration hosted in a sericitized gabbro, with local visible gold.
