Osisko Metals Provides Update on the Pine Point Project and Feasibility Study

MONTREAL, Nov. 04, 2024 (GLOBE NEWSWIRE) -- Osisko Metals Incorporated (the "Company" or "Osisko Metals") (TSX-V: OM; OTCQX: OMZNF; FRANKFURT: 0B51) is pleased to announce that the Pine Point Mining Limited (“PPML”) Feasibility Study (“FS”) is now fully underway, with an expected completion date in Q2 2025.

Since early 2023, PPML has engaged with its key technical and strategic advisors to optimize the 2022 Preliminary Economic Assessment Update (‘’PEA’’). The objective was to complete Definition Studies to compare key concepts, otherwise known as trade-off studies, typically performed during the Pre-Feasibility study stage.

Since November of 2023, PPML and the team have conducted and thoroughly analyzed various technical trade-off studies to better define the FS final design concept. In Q3 2024, PPML’s Board of Directors approved the company’s final design concept to be developed in the FS. The FS will use the Mineral Resource Estimate announced on June 25th, 2024, that reported 49.5MT of Indicated Mineral Resources Grading 5.52% ZnEq and 8.3Mt of Inferred Mineral Resources Grading 5.64% ZnEq (see note below under “About Osisko Metals”).

These more detailed design concepts will bridge the Project from a PEA level into the FS stage and support concurrent Environmental Assessment and Permitting activities. A significant change is that the preconcentration methods proposed in the 2020 & 2022 PEA studies (i.e. XRF Ore Sorting, Dense Media Separation) will not be incorporated in the concentrator design in favour of conventional “Full Milling”. This will have an overall better recovery of zinc and lead and will reduce operational risk with the simpler flow sheet. Other concepts that were analyzed in detail were the use of former Cominco Era open pits to dispose of waste rock and tailings as much as possible. All key concepts will be presented to communities for feedback in upcoming community meetings planned for November 2024.

The PPML team relies on the experience of Qualified Persons working for established engineering firms, including Synectiq, BBA, GMining, Newfields, Terrane Geoscience, and WSP, to develop the Feasibility Study and advance permitting. WSP has local offices in the Northwest Territories and the experience needed for permitting in the North.

This summer, PPML had two weeks of site visits where the Project was presented to Government representatives, community leaders and members and environmental regulators and we thank them for their participation.
