Osisko Metals Expands Leadership Team And Announces C$100 Million Bought Deal Financing

MONTREAL, Nov. 18, 2024 - Osisko Metals Inc. (the "Company or "Osisko Metals") (TSXV: OM) (OTCQX: OMZNF) (FRANKFURT: 0B51) is pleased to announce the expansion of its leadership team along with a C$100 million bought deal financing (the "Transaction") as the Company accelerates its strategy of creating a leading critical metals company in North America.

John Burzynski will be appointed to the board of directors of the Company (the "Board") as Executive Chairman and will lead the Company along with Robert Wares, who will continue as Chief Executive Officer and a Director on the Board. Don Njegovan and Blair Zaritsky will be appointed as President and Chief Financial Officer of the Company, respectively. Additionally, Luc Lessard, a director of the Company since 2019, will step down from the Board and Anthony Glavac will step down as Chief Financial Officer. Mr. Lessard will remain as technical advisor to the Board.

In conjunction with the Transaction, the Company has entered into an agreement with Canaccord Genuity Corp. as sole bookrunner and co-lead underwriter together with BMO Capital Markets and National Bank Financial for a syndicate of underwriters (collectively, the "Underwriters"), pursuant to which the Underwriters have agreed to purchase, subject to certain conditions, 288,465,000 units of the Company (the "HD Units") at a price of C$0.26 per HD Unit for gross proceeds of C$75 million and 50,000,000 flow-through units of the Company (the "FT Units") at a price of C$0.50 per FT Unit for gross proceeds of C$25 million. The aggregate gross proceeds from issuance of HD Units and FT Units will be C$100 million.

Each HD Unit consists of one common share of the Company (each, a "Common Share") and one-half of one transferrable common share purchase warrant of the Company (each, a Warrant"). Each FT Unit consists of one Common Share and one-half of one Warrant, each of which will qualify as "flow-through shares" within the meaning of subsection 66(15) of the Income Tax Act (Canada) and section 359.1 of the Taxation Act (Québec). Each Warrant will entitle the holder to purchase one Common Share of the Company at a price of 0.35 per Common Share for a period of two years following the closing of the Transaction.

The Company has also granted the Underwriters an option (the "Underwriters' Option"), exercisable in whole or in part, at any time up to the closing date of the Transaction, to acquire up to an additional C$15 million in any combination of HD Units and FT Units. In consideration for the Underwriters' services, the Company will pay the Underwriters a cash commission equal to 5.0% of the gross proceeds of the Transaction (including the additional proceeds realized upon the exercise of the Underwriters' Option, if applicable).

The Company intends to use the proceeds of the Transaction towards the advancement of its Gaspé Copper project to a construction decision, and for general corporate purposes. The gross proceeds from the FT Units will be used by the Company to incur eligible "Canadian exploration expenses" that qualify as "flow-through mining expenditures" (as both terms are defined in the Income Tax Act (Canada)) (the "Qualifying Expenditures") related to the Company's projects in Québec. The Qualifying Expenditures will be renounced in favour of the subscribers with an effective date no later than December 31, 2024. In addition, with respect to subscribers who are eligible individuals under the Taxation Act (Québec), the Qualifying Expenditures will also qualify for inclusion in the "exploration base relating to certain Québec exploration expenses" within the meaning of section 726.4.10 of the Taxation Act (Québec) and for inclusion in the "exploration base relating to certain Québec surface mining exploration expenses" within the meaning of section 726.4.17.2 of the Taxation Act (Québec).

Closing of the Transaction is expected to take place on or about December 10, 2024 (the "Closing Date"), and is subject to certain conditions including, but not limited to, the conditional and final approval of the TSX Venture Exchange. All securities issued under the Transaction will be subject to a hold period expiring four months and one day from the Closing Date.

The HD Units and FT Units are to be offered for sale by way of private placement in all the provinces of Canada, pursuant to applicable prospectus exemptions under National Instrument 45-106 - Prospectus Exemptions. The Underwriters will also be entitled to offer the HD Units for sale to eligible purchasers resident in the United States pursuant to available exemptions from the registration requirements of the United States Securities Act of 1933, as amended (the "U.S. Securities Act"), and in those other jurisdictions outside of Canada and the United States provided that no prospectus filing or comparable obligation arises in such other jurisdiction.

This news release does not constitute an offer to sell or a solicitation of an offer to buy any of the securities in the United States. The securities have not been and will not be registered under the U.S. Securities Act, or any state securities laws and may not be offered or sold within the United States or to or for the account or benefit of a U.S. person (as defined in Regulation S under the U.S. Securities Act) unless registered under the U.S. Securities Act and applicable state securities laws or an exemption from such registration is available.

Robert Wares, Chief Executive Officer, commented: "We are thrilled to welcome the new members of the Osisko Metals team whose extensive industry expertise and proven track record of creating shareholder value will be invaluable as we drive forward with our strategic goals. The Transaction will provide the capital needed to advance the Gaspé Copper project to a construction decision in a safe, inclusive and socially responsible manner. With a stronger balance sheet and an expanded team, we are well-positioned to unlock the full potential of our assets and achieve success in the coming years. The Board would like to thank Anthony Glavac and Luc Lessard for their dedication and contributions to the Company and wish them well with their future endeavors."

John Burzynski, incoming Executive Chairman, commented: "The Gaspé Copper project is one of the most promising and largest untapped copper projects in North America. Our team has an unparalleled track record of value creation in Québec - first with Canadian Malartic and most recently with Windfall - and we look forward to recreating that success at Gaspé. Shareholders of Osisko Metals stand to benefit from the growing demand for copper, and will have considerable exposure to a quickly growing deposit through the Gaspé Copper project. I am excited to collaborate with the management team and Board as we join forces to create a leading critical metals company in North America. Lastly, we are also pleased to welcome Franco Nevada Corp as a strategic investor in Osisko Metals."
