Osisko Intersects 94 Metres Averaging 1.47% Cu at Gaspé
Includes 5.3 Metres Averaging 8.31% Cu and 51.0 g/t Ag
MONTRÉAL, Oct. 07, 2026 (GLOBE NEWSWIRE) -- Osisko Metals Incorporated (the “Company” or “Osisko Metals”) (TSX: OM; OTCQX: OMZNF; FRANKFURT: 0B51) is pleased to announce additional new analytical results from the ongoing 2026 drill program at the Gaspé Copper Project, located in the Gaspé Peninsula of Eastern Québec. New results are presented below (see Table 1), including 38 mineralized intercepts from 12 drill holes. Reported “infill” intercepts are located within the 2026 MRE model (see April 14, 2026 news release), focused on upgrading Inferred Mineral Resources to Measured or Indicated categories, as applicable. “Expansion” intercepts are located outside the 2026 MRE model and comprise either i) in-pit expansion, which offers potential to convert in-pit waste into additional resources within the 2026 MRE Whittle pit; or ii) out-of-pit expansion, consisting of mineralization located outside the 2026 MRE Whittle pit, which may potentially lead to the definition of new resources. Some of the reported intercepts may have contiguous shallower infill as well as deeper in-pit expansion (noted as “Both”). Maps showing hole locations are available at www.osiskometals.com.
Osisko Metals Chief Executive Officer Robert Wares commented: “This new set of holes includes excellent results from infill drilling within the 2026 MRE model, particularly from holes 30-1251 and 30-1258. Hole 30-1251 intersected impressive high-grade mineralization in porcellanite above the historic E Zone underground workings, returning 94.4 metres averaging 1.47% Cu.”
Wares continued: “It has been our experience over the years that great deposits are full of great surprises. Hole 30-1258 appears to be just one of those types of surprises, having intersected 121 metres averaging 0.71% Cu hosted in a previously unknown porphyry intrusion below the E Zone skarn horizon at the south end of Copper Mountain. This new porphyry intrusion contains significant copper stockwork and veining, and it represents the first evidence of porphyry-hosted mineralization south of the main pit area. It may be indicative of a potential third, previously unknown (and untested) mineralized porphyry centre in the Gaspé Copper system, distinct from the two historically known porphyries in the main pit area and at the Porphyry Mountain DPEX target. Additional drilling will be designed to further test this interpretation.”

Additional comments
Drill holes 30-1248, 30-1249, 30-1253 and 30-1254, all located south and southwest of the Needle Mountain pit, tested areas where little mineralization was expected from historical drilling. All holes, with the exception of 30-1253, yielded multiple decametric mineralized intersections with grades ranging from 0.19% Cu to 0.50% Cu.
Drill hole 30-1250, located on the north slope of Needle Mountain, is an expansion hole that threaded through pillars of the C Zone underground workings, intersecting higher grades around and within the C Zone skarn horizon.
Drill hole 30-1259 is located on top of Needle Mountain East, approximately 320 metres south of the southern limit of the 2026 MRE model and near the southern extremity of the 2026 Whittle pit model. It is an expansion hole that intersected five decametric mineralized intervals with grades ranging from 0.12% Cu to 0.45% Cu. Mineralization was extended in this area to a vertical depth of 420 metres, indicating that the deposit is still open to the south, beyond the peak of Needle Mountain East.
Drill holes 30-1251, 30-1252, 30-1255, 30-1256, 30-1257 and 30-1258, all located near Copper Brook at the southern portion of the 2026 MRE model, are infill holes that intersected mineralization in line with the 2026 MRE block model, with the exception of higher-than-expected grades in 30-1251 and 30-1258, as discussed above.
Mineralization at Gaspé Copper is of porphyry copper/skarn type and occurs as disseminations and stockworks of chalcopyrite with pyrite or pyrrhotite and minor bornite and molybdenite. One prograde and at least five retrograde vein/stockwork mineralizing events have been recognized at Copper Mountain, which overprint earlier, stratiform, carbonate replacement skarn and porcellanite-hosted mineralization throughout the Gaspé Copper system. Porcellanite is a historical mining term used to describe bleached, pale green to white potassic-altered hornfels. Subvertical stockwork mineralization dominates at Copper Mountain whereas prograde bedding-parallel mineralization, which is mostly stratigraphically controlled, dominates in the area of lower Copper Mountain, Needle Mountain, Needle East, and Copper Brook. High molybdenum grades (up to 0.5% Mo) were locally obtained in both the C Zone and E Zone skarns away from Copper Mountain.

The 2022 to 2024 Osisko Metals drill programs were focused on defining open-pit resources within the Copper Mountain stockwork mineralization (see May 6, 2024 MRE press release). Extending the resource model south of Copper Mountain into the poorly-drilled prograde skarn/porcellanite portion of the system subsequently led to a significantly increased resource, mostly in the Inferred category (see November 14, 2024 MRE press release), and additional drilling in 2025 led to an additional significant increase in resources, mostly in the Measured and Indicated categories (see April 14, 2026 MRE press release).
The current drill program is designed to convert the bulk of the remaining 2026 MRE Inferred resources to Measured and Indicated categories, as well as test the expansion of the overall resource laterally to the west, and to the south/southwest towards Needle East and Needle Mountain respectively.
Copper Equivalent (CuEq) grades are presented for illustrative purposes only to express the combined value of copper, molybdenum, and silver as a single copper grade. CuEq grades are calculated using long-term metal prices of US$4.50/lb copper, US$20.00/lb molybdenum, and US$45.00/oz silver, and incorporate assumptions for metallurgical recoveries, payable metal factors, smelting and refining charges, transportation costs, and royalties. Hence the CuEq calculation is essentially based on net smelter return (NSR) values. NSR for each metal is estimated by applying metallurgical recoveries, payable factors, metal prices, and applicable smelting, refining, transportation, and penalty charges to the in-situ metal grades. CuEq grades are derived using a linear regression relationship established between copper grade and copper NSR, and then calculated by substituting total NSR (Cu + Mo + Ag) for copper NSR in the regression equation. The simplified formula is expressed as CuEq (%) = Cu (%) + 3.40327 × Mo (%) + 0.00008 × Ag (g/t)

Quality Assurance / Quality Control
Mineralized intervals reported herein are calculated using an average 0.12% CuEq lower cut-off over contiguous 20-metre intersections (shorter intervals as the case may be at the upper and lower limits of reported intervals). Intervals of 10 metres or less are generally not reported unless considered material. True widths are estimated at 80 – 90 % of the reported core length 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 drilled in HQ or NQ diameter and 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. Sample preparation details (code PREP-31DH) are available on the ALS Canada website. 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 Cu, Mo and Ag.
