Osisko Metals

Investor Insight

Osisko Metals’ high-quality copper and zinc assets present a compelling investment opportunity amid a rapidly expanding critical and base metals market. North America is continuing to prioritize domestic mineral supply chains, and Osisko Metals is well-positioned with its two brownfield, past-producing assets in Canada: the Gaspé Copper project and the Pine Point zinc-lead project.

Overview

Osisko Metals (TSXV:OM,OTC:OMZNF,FRANKFURT: 0B51) is an exploration and development company focusing on two base metal assets in Canada – Gaspé Copper and Pine Point – targeting copper and zinc, both critical minerals necessary for the global transition to clean energy. These assets are past-producing, brownfield projects of significant potential for future production.

The Gaspé Copper project in Québec has a rapid development plan to begin mining the indicated resource of 824 million tons (Mt) of ore grading 0.34 percent copper equivalent. As the gap between available copper supply and growing demand widens, Osisko Metals is well-positioned to help create and strengthen a domestic supply chain for the North American market.

The company’s Pine Point zinc-lead project in the Northwest Territories contains an indicated mineral resource estimate of 49.5 Mt at 4.22 percent zinc and 1.49 percent lead, in addition to significant inferred resources. Zinc is a necessary mineral for the clean energy transition and has important applications throughout the manufacturing industry. This widespread use of zinc has analysts cautioning about a looming supply shortage.

A preliminary economic assessment (PEA) completed in 2022 indicates the Pine Point project has the potential to become a world-class, high-grade zinc asset, with an after-tax net present value (NPV) of C$602 million and internal rate of return (IRR) of 25 percent. A feasibility study is now fully underway, and is expected to be completed in 2025.

In February 2023, Osisko Metals announced a C$100-million investment agreement with Appian Natural Resources Fund III for a joint venture on the Pine Point project. The agreement includes C$75.3 million of funding for the project and up to C$24.7 million in cash payments to Osisko Metals. In February 2024, Osisko Metals sold an additional 5 percent ownership interest in Pine Point Mining to a subsidiary of Appian for approximately C$8.33 million. Appian now has the right to earn up to 65 percent of the project, with Osisko Metals retaining 35 percent.

Pine Point Mining and the Town of Hay River have also signed a memorandum of understanding to seize opportunities for long-term sustainable growth for Hay River through the development and operations of the Pine Point mining project.

Led by a management team with a wide range of expertise throughout the natural resources industry and experience in geology, exploration, corporate finance and corporate administration, Osisko Metals is well-poised to become a world-class supplier of base metals.

Key Projects

Gaspé Copper Project

The Gaspé Copper project in Québec is among the most significant copper development projects in eastern North America. Osisko Metals completed the 100-percent acquisition of Gaspé Copper in July 2023 and has since launched a fully funded, 110,000-metre drill program. Québec is consistently ranked as a top-tier mining jurisdiction with supportive permitting processes and access to infrastructure.

Project Highlights:

• Significant Mineral Resource Estimate: The current NI 43-101 mineral resource estimate (effective November 2024) outlines an in-pit indicated resource of 824 Mt grading 0.34 percent copper equivalent and an inferred resource of 670 Mt grading 0.38 percent copper equivalent. Contained metals include 4.91 billion pounds of copper, 274 million pounds of molybdenum, and 46 million ounces of silver.
• Promising Metallurgy: Metallurgical testing demonstrates copper recoveries of 92 to 94 percent and molybdenum recoveries of 65 to 70 percent. The copper concentrate grades range from 24 to 28 percent, while molybdenum concentrate grades reach 59 percent. Payable silver credits are included in the copper concentrate. Osisko Metals has a copper offtake agreement in place with Glencore.
• Prolific Past Production: The historic Gaspé mine produced more than 141 Mt at 0.9 percent copper between 1955 and 1999 through both underground and open-pit mining. The site has undergone over C$150 million in reclamation, creating a well-positioned brownfield development opportunity.
• Robust Infrastructure: The site benefits from year-round road access, on-site hydroelectric power, proximity (under 100 km) to a deep-sea port in Gaspé, and remaining legacy infrastructure, including oxide stockpiles, administration buildings and a water treatment facility.
• 2025 Drill Program: The 110,000-metre drill campaign initiated in February 2025 targets both infill and expansion zones. Goals include upgrading inferred resources, extending mineralization up to 250 meters below the current pit shell, testing areas toward Needle East Mountain, and better delineating high-grade skarn zones (grading 0.5 to 3.0 percent copper). Recent results include:
  • Drill hole 30-1090 – 279.0 meters averaging 0.49 percent copper and 108.0 meters averaging 0.84 percent copper
    Drill hole 30-1075 – 258.0 meters averaging 0.33 percent copper including 15.6 meters averaging 1.47 percent copper

• Wide zones of new mineralization intersected southeast of the Copper Mountain pit, including skarn-hosted copper zones supporting potential for future resource expansion

• Copper Mountain Updated MRE: The latest resource estimate (Fall 2024) reflects a 53 percent increase in copper-equivalent content in the indicated category and a 100-fold increase in the inferred category compared to prior reports. A high-grade sub-resource of 520 Mt grading 0.54 percent copper equivalent has also been identified at higher cut-off grades.
• 2025–2028 Work Program: The plan includes the ongoing drill campaign, environmental and socio-economic impact assessments, a PEA in 2026, and a feasibility study in 2027. Permitting and public hearings are targeted for 2029, followed by financing and construction in 2030–2031, and potential production start-up in 2032.
• Acquisition of New Claims: In December 2024, Osisko Metals acquired 199 additional mineral claims adjacent to the Gaspé Copper property, expanding the project’s exploration footprint in a highly prospective area.

Pine Point Zinc-Lead Project

The Pine Point asset in the Northwest Territories is a brownfield site with legacy infrastructure and a clear path toward redevelopment. The site is supported by an on-site hydroelectric substation, paved access roads, and proximity to rail and port infrastructure.

Project Highlights:

• Joint Venture: Pine Point Mining, the project operator, is governed under a joint venture between Osisko Metals and Appian Natural Resources Fund III. The C$100-million agreement includes C$75.3 million in project funding and additional cash payments. In February 2024, Osisko Metals sold an additional 5 percent interest to Appian for C$8.33 million. Appian may earn up to 65 percent ownership; Osisko Metals retains 35 percent.
• High-grade Clean Concentrates: The project is expected to produce exceptionally clean zinc and lead concentrates, as confirmed by recent metallurgical testing. XRT sorting and flotation achieved recoveries of 87 percent for zinc and 93 percent for lead. Low deleterious element levels make Pine Point’s product highly attractive to smelters seeking premium concentrates.
• Promising Economics: The 2022 PEA outlines an average annual life-of-mine production of 329 million pounds of zinc and 141 million pounds of lead. It projects an after-tax NPV (8 percent) of C$602 million and an IRR of 25 percent. Estimated dewatering volumes were reduced by 30 percent compared to the 2020 PEA.
• 2024 Updated Mineral Resource Estimate:

• Indicated: 49.5 Mt grading 4.22 percent zinc and 1.49 percent lead (5.52 percent zinc equivalent), containing 4.6 billion lbs of zinc and 1.6 billion lbs of lead
• Inferred: 8.3 Mt grading 4.18 percent zinc and 1.69 percent lead (5.64 percent zinc equivalent), containing 0.7 billion lbs of zinc and 0.3 billion lbs of lead
• East Mill, Central, and North zones collectively hold ~36.2 Mt of indicated resources grading 5.22 percent zinc equivalent

• Community Support: Pine Point Mining Limited has secured support through collaboration agreements with Deninu K’ue First Nation and the Northwest Territory Métis Nation, and continues to work under a 2017 exploration agreement with K’atl’odeeche First Nation. A memorandum of understanding was signed in November 2024 with the Town of Hay River to promote long-term economic benefits and local participation.
