OSISKO INTERSECTS 748 METRES AVERAGING 0.27% Cu AT GASPÉ
(Montreal, January 15, 2026) Osisko Metals Incorporated (the “Company” or “Osisko Metals“)  (TSX: OM; OTCQX: OMZNF; FRANKFURT: 0B51) is pleased to announce new drill results from the Gaspé Copper Project, located in the Gaspé Peninsula of Eastern Québec.

New analytical results are presented below (see Table 1), including 35 mineralized intercepts from ten new drill holes. Infill intercepts are located inside the 2024 MRE model (see November 14, 2024 news release), and are focused on upgrading inferred mineral resources to measured or indicated categories, as applicable. Expansion intercepts are located outside the 2024 MRE model and may potentially lead to additional resources that will be classified appropriately within the next MRE update. Some of the reported intercepts have contiguous shallower infill as well as deeper expansion (noted on Table 1 below as “Both”).

The Company understands that Agnico Eagle Mines Limited and Hudbay Minerals Inc., two of its existing strategic investors, along with Toronto-based fund Rosseau Asset Management Ltd., have purchased, as part of a follow-on transaction to the issuance of the Flow-Through Shares, all of the Common Shares issued under the Offering at a price of C$0.85 per Common Share for an aggregate purchase price of approximately C$10 million.

The Flow-Through Shares issued under the Offering are subject to a hold period expiring four months and one day from the date of issuance, pursuant to applicable Canadian securities laws. The Offering remains subject to final acceptance of the Toronto Stock Exchange.

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 of 1933, as amended (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.

Re-assayed historical core from DDH 30-0943 returned 852.0 metres averaging 0.70% Cu, 2.92 g/t Ag and 0.062% Mo (0.95% CuEq*) from 998.0 to 1850.0 metres, which confirms previously obtained historical results (see Table 1 below).  Many of the historical holes drilled by previous operators that reached the lower portion of the Porphyry Mountain deposit were stopped in mineralization (see Table 1 below), demonstrating that the deposit remains open at depth.

Osisko Metals Chief Executive Officer Robert Wares commented: “These very promising results launch our 2026 DPEX resource evaluation program at Porphyry Mountain. Following the anticipated Q1 2026 release of our MRE update on the GCP Copper Mountain deposit, and in addition to the currently planned 2026 expansion drilling on the GCP Needle Mountain and Needle East zones, the DPEX resource evaluation program on Porphyry Mountain will include deep drilling on the deposit and thorough re-assaying of available historical drill core. This should establish its true depth and reveal the full potential of the deposit, with the objective of releasing a maiden Inferred MRE on Porphyry Mountain by the end of 2026. We anticipate that the updated GCP Copper Mountain open pit will reach significant depths near the end of its mine life, and this would potentially allow for future ramp access to the deeper, higher-grade DPEX Porphyry Mountain deposit.”
