The Offering is expected to close on or about December 22, 2021 and is subject to certain closing conditions including, but not limited to, the receipt of all necessary approvals including the conditional listing approval of the TSX Venture Exchange and the applicable securities regulatory authorities. The Offering is being made by way of private placement in Canada. The securities issued under the Offering will be subject to a hold period in Canada expiring four months and one day from the closing date of the Offering.

The securities offered have not been registered under the U.S. Securities Act of 1933, as amended, and may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements. This news release shall not constitute an offer to sell or the solicitation of an offer to buy nor shall there be any sale of the securities in any State in which such offer, solicitation or sale would be unlawful.

About Osisko Metals

Osisko Metals Inc. is a Canadian exploration and development company creating value in the base metal space. The Corporation controls two of Canada's premier past-producing zinc mining camps: 1) the Pine Point Project that is located in the Northwest Territories, for which the most-recently filed PEA in July 2020 has indicated an after-tax NPV of $500M and an IRR of 29.6%. The Pine Point Project PEA is based on current Mineral Resource Estimates that are amenable to open pit and shallow underground mining and consist of 12.9Mt grading 6.29% ZnEq of Indicated Mineral Resources and 37.6Mt grading 6.80% ZnEq of Inferred Mineral Resources. Please refer to the technical report entitled "Preliminary Economic Assessment, Pine Point Project, Hay River, North West Territories, Canada" dated July 30, 2020 (with an effective date of June 11, 2020), which has been prepared by BBA Inc. and WSP Canada Inc. for Osisko Metals, a copy of which is available on SEDAR (www.sedar.com) under Osisko Metals' issuer profile. The Pine Point Project is located on the south shore of Great Slave Lake in the Northwest Territories, near infrastructure, paved highway access, and has 100 kilometres of viable haulage roads already in place; 2) The Bathurst Mining Camp projects are located in northern New Brunswick. The company has optioned the majority of its holding in the Bathurst Camp to Brunswick Exploration, pending TSXV approval for the transaction.

The current Mineral Resources mentioned in this news release conform to National Instrument 43-101 - Standards of Disclosure for Mineral Projects and were prepared by independent qualified persons, as defined by NI 43-101 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).
