Osisko Metals Incorporated (the " Company " or " Osisko Metals ") ( TSX-V: OM ; OTCQX: OMZNF ; FRANKFURT: 0B51 ) is pleased to announce that, further to its news release dated July 11, 2022 (entitled "Osisko Metals Exercises Option to Acquire Gaspé Copper Project"), it has completed the acquisition (the " Transaction ") of a 100% interest in the past-producing Gaspé Copper Mine (" Gaspé Copper ") pursuant to a purchase agreement dated July 8, 2022 between the Company and Glencore Canada Corporation, a wholly-owned subsidiary of Glencore plc (" Glencore ").

Robert Wares, Chairman & CEO of Osisko Metals, commented : "The acquisition of the Gaspé Copper Project is a milestone for the Company that provides shareholders with significant copper exposure in the mining-friendly province of Québec. Last year's excellent drill results at Gaspé support our belief in the high-value potential of this asset and we are convinced that the acquisition of Gaspé Copper, together with our ongoing development of our joint-ventured Pine-Point project, positions Osisko Metals as a premier base metal development company in Canada. I wish to thank both the Osisko Metals and Glencore teams, as well as all stakeholders, for their diligence and perseverance in completing this complex transaction that will no doubt benefit all parties and shareholders."

In connection with the Transaction:

• Glencore was issued a US$25.0 million senior secured convertible note (the " Convertible Note ") of the Company which is convertible into units of Osisko Metals at a price of $0.40 per unit (each, a " Unit "), comprised of one common share of the Company (each, a " Common Share ") and one-half Common Share purchase warrant of the Company (each whole warrant, a " Warrant "). Each Warrant will be exercisable by Glencore at an exercise price of $0.46 per Common Share until July 14, 2026.The Convertible Note will bear interest at a rate equal to the Secured Overnight Financing Rate (SOFR) + 4%, payable annually and, subject to adjustment or acceleration in certain circumstances, all outstanding principal and interest under the Convertible Note will be repaid in full by July 14, 2026. The Convertible Note will be secured against all of the present and after acquired property of the Company. Upon full conversion of the Convertible Note (assuming conversion on the closing date) and exercise of the underlying Warrants in full, Glencore would acquire 71,347,826 Common Shares, representing approximately 21.8% of the Common Shares that would be issued and outstanding upon the conversion of the Convertible Note and the exercise of the Warrants issued upon such conversion. Glencore did not own or control, directly or indirectly, any securities of Osisko Metals immediately prior to the closing of the Transaction.
• Glencore retained a 1% net smelter returns (" NSR ") royalty on the historical Mount Copper open pit and a 3% NSR royalty on all other minerals extracted from Gaspé Copper.
• Osisko Metals will make a cash payment of US$20.0 million to Glencore upon the commencement of commercial production at Gaspé Copper.
• Osisko Metals is required to incur a total of $55.0 million in exploration, development and environmental expenditures, including permitting expenditures, over a period of four years, which commenced on March 25, 2022, with a minimum of $20.0 million to be incurred by March 25, 2024.
• Osisko Metals has entered into an offtake agreement with Glencore to purchase 100% of the concentrates produced at Gaspé Copper.
• The Company and Glencore entered into an investor rights agreement (the " Investor Rights Agreement "), pursuant to which Glencore has been granted certain investor rights, provided that it maintains certain ownership thresholds in the Company. Among other things, the Investor Rights Agreement provides Glencore with the right to designate one director for appointment to the board of directors of the Company, participation rights in future equity issuances, piggyback registration rights and the right to maintain its pro-rata position in Osisko Metals.

Upon conversion of the Convertible Note by Glencore, Glencore may hold, on a post-conversion basis, such number of Common Shares and Warrants that would exceed 20% of the pro forma issued and outstanding Common Shares, both on a non-diluted and partially-diluted, post-conversion basis, thus resulting in Glencore becoming a Control Person (as such term is defined in the policies of the TSX Venture Exchange (the " Exchange ")) of the Company. Accordingly, in accordance with the policies of the Exchange, the disinterested shareholders of the Company were required to approve Glencore as a Control Person of the Company, which approval was obtained at a meeting of shareholders held on June 23, 2022. For more information, please refer to the management information circular of the Company dated May 11, 2022, a copy of which is available on SEDAR (www.sedar.com) under the Company's issuer profile.

In accordance with the terms of the Investor Rights Agreement, Mr. Peter Wright will be appointed to the board of the Company. Mr. Wright has served as Director and Vice President, Legal, with Glencore since 2018, having joined the company in 2014. Previously, Mr. Wright practiced corporate law in Toronto with Torys LLP and Cassels, Brock & Blackwell LLP as well as in New York with Paul, Weiss, Rifkind, Wharton & Garrison LLP. Mr. Wright graduated from the McGill Faculty of Law with Great Distinction in 2004 (BCL/LLB) and has since been called to the bars of Ontario (2005) and New York (2006).

About Gaspé Copper

Gaspé Copper, a 44-year former copper and molybdenum producer that was initially operated by Noranda Inc., is located next to the community of Murdochville, in the Gaspé Peninsula of Eastern Quebec, approximately 825km east of Montreal. Most support infrastructure for the potential re-opening of Gaspé Copper is already in place. The former mine site benefits from paved road access with local highway 198 linking Murdochville with the coastal community of Gaspé.

As of the date hereof, the Company has completed approximately 28,000 meters of drilling at Gaspé Copper in accordance with the recommended work program outlined in the Technical Report (as defined below). Between 6,000 meters and 10,000 meters in additional drilling is expected to be completed by the Company during the 2023-2024 drill program. A reconciliation of the proposed work program against the work program recommended in the Technical Report is provided in the table below.

Note :

1. After executing the 2022 program, it is now expected that a total of up to 38,000 meters in drilling will be needed to complete the recommended work program as outlined in the Technical Report.
2. Approximately 28,000 meters of drilling has been completed as at June 30, 2023. Increased meterage associated with the execution of the 2022 drill program is due to the adjusted location of drill collars with respect to the recommended program in the Technical Report. In particular, due to safety reasons, all holes had to be collared on the periphery of the pit, which resulted in drilling added meterage through barren rock in order to obtain recommended meterage within the mineralized zone. Additional drilling is therefore required in the 2023 to fully meet the objectives recommended in the Technical Report.
3. Represents costs associated with completing between 6,000 meters and 10,000 meters in additional drilling on the property, bringing the total size of the drill program to approximately 38,000 meters. Due to confirmation that the highest-grade material is located in the core of the pit, additional drilling focused on the core of the pit is needed to maximize resource conversion in that area.
4. For a summary of the results of all drilling completed at Gaspé Copper since the effective date of the Technical Report, please refer to the news release dated August 4, 2022 entitled "Osisko Metals Reports First Infill Drill Results at Gaspe Copper" , the news release dated October 27, 2022 entitled "Osisko Metals Reports Additional Infill Drill Results at Gaspe Copper Including 102.0 m of 0.57% Copper and 2.20 gpt Silver" , the news release dated January 24, 2023 entitled "Osisko Metals Reports Additional Drill Results at Mount Copper Including 1011.0 Metres Grading 0.46% Copper and 3.19 g/t Silver" and the news release dated April 3, 2023 entitled "Osisko Metals Reports Additional Drill Results at Mount Copper Including 300.0 Metres Grading 0.55% Copper and 3.59 g/t Silver" , copies of which are available on SEDAR (www.sedar.com) under the Company's issuer profile.
