Southern Extension provides additional high-grade
intercept of 51 metres averaging 1.24% Cu
92.9 metres averaging 0.35% Cu from historic hole located
625 metres south of the 2024 MRE model
MONTREAL, Feb. 25, 2026 -- Osisko Metals Incorporated (the " Company" or " Osisko Metals") (TSX: OM; OTCQX: OMZNF;
FRANKFURT: 0B51) is pleased to announce new drill results and re-analysis results from historic drill core from the Gaspé
Copper Project, located in the Gaspé Peninsula of Eastern Québec.
Osisko Metals Chief Executive Officer Robert Wares commented: “These new results include three holes for the Southern
Extension, again demonstrating that the deposit is wide open to the south. Drill hole 30-1177, located 150 metres south of the
limit of the 2024 MRE model, intersected 315 metres averaging 0.42% Cu, including another high-grade zone of 51 metres
averaging 1.24% Cu. Moreover, re-assaying of historical Noranda holes further to the south revealed more positive results, with
drill hole 30-0888, located 625 metres south of the limit of the 2024 MRE model, producing 92.9 metres averaging 0.35% Cu
from surface and 30-0874 producing 59.8 metres averaging 0.28% Cu. We look forward to the updated MRE on Gaspé Copper
due to be released towards the end of March.”
New analytical results are presented below (see Table 1), including 53 mineralized intercepts from 19 new, and 2 re-assayed
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”). Maps showing hole locations are available at www.osiskometals.com .

Discussion
Southern Extension holes: Drill hole 30-1177 was drilled vertically through a B-Zone pillar, down to a level just below the E-
Zone. It was located 150 metres south of the southern limit of the 2024 MRE model and intersected 315.0 metres averaging
0.42% Cu and 4.13 g/t Ag, including a high-grade intercept in the P1-W1-P2 units (hosting the B-Zone) that comprised 51
metres averaging 1.24% Cu and 14.5 g/t Ag. Drill hole 30-0874 and 30-0888 were historical Noranda holes from which
preserved core was re-assayed, drilled vertically and located on top of Needle East Mountain, 535 metres and 625 metres
south of the southern limit of the 2024 MRE model, respectively. Drill hole 30-0874 intersected 59.8 metres averaging 0.28%
Cu and 3.08 g/t Ag, while drill hole 30-0888 intersected 92.9 metres averaging 0.35% Cu and 4.78 g/t Ag, demonstrating that
the deposit is open to the south for at least 600 metres beyond the southern limit of the 2024 MRE model.
Drill holes 30-1158, 30-1163, 30-1175 and 30-1178 were drilled at or just outside the eastern and western margins of the 2024
MRE model in order to confirm portions of the outer limits of the deposit. All four holes intersected little or sporadic
mineralization, as expected.
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, bedding 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).
The current drill program is 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. The November 2024 MRE was limited at depth to the base of the L1 skarn horizon (C
Zone), and all mineralized intersections below this horizon represent potential depth extensions to the deposit, to be included
in the next scheduled MRE update in Q1 2026.
Most holes are being drilled sub-vertically into the altered calcareous stratigraphy that dips 20 to 25 degrees to the north. The
L1 (C Zone) the L2 (E Zone) skarn/marble horizons were intersected in most holes, as well as intervening porcellanites that
host the bulk of the disseminated copper mineralization.
