Osisko Metals Inc. Reports First Infill Drill Results at Gaspé Copper

MONTREAL, Aug. 04, 2022 - Osisko Metals Incorporated (the "Company" or "Osisko Metals") (TSX-V: OM; OTCQX: OMZNF; FRANKFURT: 0B51) is pleased to announce initial drilling results from the Gaspé Copper project, located in the Gaspé Peninsula of Quebec. Infill drilling at the Mount Copper deposit has thus far demonstrated a limited extent of oxidation and significant mineralization beyond the currently modeled (pit-constrained) Inferred Mineral Resource Estimate (“MRE”, see April 28, 2022 press release). Results from sixteen holes are reported below, and all except DDH 30-0976 are from the Mount Copper area on the southeast side of the deposit (see map).


Highlights include:

- Of the sixteen drill holes reported below, fourteen extended disseminated/stockwork copper-silver mineralization outside the current pit-constrained resource model, including up to 170 metres in drill hole 30-0991 below the currently designed pit floor. All fourteen holes ended in mineralization above or within the C Zone skarn horizon.

- Drill hole 30-0977, located 142.0 metres south of the modelled pit, intersected 375.3 metres grading 0.20% Cu and 1.31g/t Ag. This hole stopped in mineralization and can be extended if warranted.

- Drill hole 30-0985 intersected 528.0 metres grading 0.26% Cu and 1.72g/t Ag, including 46.5 metres grading 1.1% Cu and 6.19g/t Ag in skarn-style disseminated mineralization in the C Zone. This hole extends 122.0 m below the currently designed pit floor and stopped in mineralization.

Robert Wares, Chairman & CEO, commented: “We are very pleased with the initial results of our 30,000-metre drill program at Gaspé Copper. Most of the reported results are from holes collared on top of Mount Copper, where historical drilling was relatively scarce. We can now confirm that this area is mineralized with limited oxide copper and that the potential for further expansion of the deposit appears to be significant as most of these holes ended in mineralization. With four drill rigs on site currently, I am excited to build upon what is already the largest undeveloped copper resource in Eastern North America.”

Mineralization reported in the table below consists of disseminated and fracture-filling stockwork chalcopyrite mineralization with minor molybdenite, hosted within potassic-altered hornfels (porcellanites) and skarn. Oxidized zones are minor and appear to be associated with regional structures where they intersect the surface. Preliminary results indicate that the oxide model used in the current MRE was most likely over-estimated and was overly conservative. The intersected mineralized intervals are consistent with historical drilling results, they confirm continuity of mineralization and meet or exceed expectations with respect to the current MRE for the Mount Copper deposit (see Map). Molybdenum assays received to date indicate values generally equal to or less than 0.1% Mo.
