Osisko Metals Advances Permitting Initiatives at Pine Point and Provides Corporate Update

MONTREAL, Sept. 24, 2020 - Osisko Metals Inc. (the "Company" or "Osisko Metals") (TSX-V: OM; OTCQX: OMZNF; FRANKFURT: 0B51) is pleased to provide an update on its permitting initiatives at its wholly owned Pine Point Project (the “Project”). Since the release of the Preliminary Economic Assessment (“PEA”), Osisko Metals has continued discussions with stakeholders and shareholders and is now advancing the Project toward the submission of an Environmental Assessment (“EA”) to governmental agencies in the fourth quarter of 2020.

Jeff Hussey, President and Chief Operating Officer, commented: “Concurrent to the restart of drilling announced last month, the forthcoming submission of the EA will mark an important milestone towards advancing the Project to a “shovel ready” stage by late 2023. Supporting the environmental work, key recommendations from the recent PEA are being initiated in preparation for a Feasibility Study. We are committed to rapidly advancing the Pine Point Project to be well positioned to take advantage of a forecasted deficit in the zinc market supply. Furthermore, we are looking forward to releasing drill results in the coming weeks.”

The current mineral resources mentioned in this press release conform to NI43-101 standards and were prepared by independent qualified persons, as defined by NI43-101 guidelines. The abovementioned mineral resources are not mineral reserves as they do not have demonstrated economic viability. The quantity and grade of the reported Inferred Mineral Resources are conceptual in nature and are estimated based on limited geological evidence and sampling. Geological evidence is sufficient to imply but not verify geological grade and/or quality of continuity. Zinc equivalency percentages are calculated using metal prices, forecasted metal recoveries, concentrate grades, transport costs, smelter payable metals and charges (see respective technical reports for details).
