- Drill hole 30-1059 intersected 300.0 metres grading 0.39% Cu and 3.17 g/t Ag within the 2024 MRE model where there was limited historical data.
- Drill hole 30-1060 intersected 220.5 metres grading 0.29% Cu and 2.09 g/t Ag within the 2024 MRE model, as well as 211.0 metres grading  0.42% Cu and 2.27 g/t Ag at depth below the 2024 MRE model, extending mineralization to a vertical depth of 598 metres.
- Drill hole 30-1063 intersected 109.5 metres grading 0.32% Cu and 2.52 g/t Ag within the 2024 MRE model, as well as 61.5 metres grading  0.33% Cu and 2.60 g/t Ag, and 43.5 metres grading  0.48% Cu and 3.20 g/t Ag at depth below the 2024 MRE model, extending mineralization to a vertical depth of 678 metres.
- Drill hole 30-1069 intersected 237.0 metres grading 0.32% Cu and 2.46 g/t Ag within the 2024 MRE model, as well as 148.8 metres grading  0.63% Cu and 4.40 g/t Ag at depth below the 2024 MRE model, extending mineralization to a vertical depth of 528 metres.
- Drill hole 30-947, an un-assayed historical hole located 110 metres south of the 2024 MRE model, was stockpiled on site and the core recovered and assayed, yielding five significant intersections, including 82.0 metres grading 0.31% Cu and 2.55 g/t Ag. These results indicate that the deposit is open to the south.
Robert Wares, Osisko Metals CEO, commented: "We are very pleased with these new drill results at Gaspé, which have exceeded our expectations. All holes intersected significant disseminated mineralization within the volume of the 2024 MRE model, and new mineralization has been added at depth well below the base of the 2024 MRE model, which was constrained to the lower contact of the C Zone skarn horizon. Drill core from historical hole 30-947 was also recovered and assayed, yielding positive results and indicating that the deposit extends laterally 110 metres south of the 2024 MRE model and remains open in that direction. This is an excellent start to the 2025 drill program, and we look forward to a regular flow of results from our 110,000-metre program as we confirm our large existing copper resource, and aim to expand it at depth, to the south and to the west towards Needle Mountain."

All drill holes were drilled sub-vertically into the Gaspé Copper altered calcareous stratigraphy that dips 20 to 25 degrees to the north; true widths are estimated at 90-92% of reported widths. The L1 (C Zone) the L2 (E Zone) skarn/marble horizons were intersected in all holes, as well as intervening porcellanites (potassic-altered hornfels) that host the bulk of the disseminated copper mineralization.
Mineralization occurs as disseminations and veinlets of chalcopyrite and is mostly stratigraphically controlled in the area of Needle Mountain, Needle East and Copper Brook. As expected, no significant molybdenum mineralization was encountered in porcellanites in the latter areas, but high grades (up to 0.4% Mo) were locally obtained in both the C Zone and E Zone skarns. The bulk of the molybdenum mineralization occurs in the stockworks further north at Copper Mountain, where true porphyry copper-style stockwork mineralization occurs, forming a distinct secondary mineralized zone that is characterized by widespread, continuous copper-molybdenum mineralization radiating from the central source of hydrothermal fluids, i.e. the Copper Mountain porphyry intrusion. At least five vein/stockwork mineralizing events have been recognized at Copper Mountain, which overprint earlier skarn/porcellanite-hosted mineralization throughout the Gaspé Copper system. The 2022 to 2024 Osisko Metals drill programs were focused on defining open-pit resources within the Copper Mountain stockwork mineralization, leading to the May 2024 MRE (see May 6, 2024 press release ). Extending the resource model south of Copper Mountain into the poorly-drilled primary skarn/porcellanite portion of the system subsequently led to a significantly increased resource, mostly in the Inferred category (see November 14, 2024 press release ).
The 2025 drill program is primarily designed to convert the November 2024 MRE to Measured and Indicated categories, as well as test the expansion of the system deeper into the stratigraphy and laterally to the south and southwest towards Needle East and Needle Mountain respectively.

Quality Assurance / Quality Control
Mineralized intervals reported herein are calculated using an average 0.12% copper lower cutoff over contiguous 20-metre intersections (shorter intervals as the case may be at the upper and lower limits of reported intervals).
Osisko Metals adheres to a strict QA/QC program for core handling, sampling, sample transportation and analyses, including insertion of blanks and standards in the sample stream. Drill core is securely transported to its core processing facility on site, where it is logged, cut and sampled. Samples selected for assay are sealed and shipped to ALS Canada Ltd.'s preparation facility in Sudbury. Pulps are analyzed at the ALS Canada Ltd. facility in North Vancouver, BC. All samples are analyzed by four acid digestion followed by both ICP-AES and ICP-MS for copper, molybdenum and silver.
