The management at Generation Mining wishes everyone a happy and safe holiday season and looks forward to 2026 being a pivotal year in our company’s growth. Generation Mining’s 2025 was defined by major milestones: a completed feasibility study, construction permits granted, expanded land holdings, strong financial positioning, and advancing its flagship Marathon Copper-Palladium Project towards construction.

2025 Highlights from the Marathon Project

Marathon Project Progress

• Feasibility Study Completed (March 2025): Delivered robust economics with an after-tax NPV of C$1.07 billion, an IRR of 28%, and a 1.9-year payback period. Recently metal prices have improved dramatically.
• Production Outlook: Over a 13-year mine life, the project is expected to produce 2.16 million oz palladium, 532 million lbs. copper, 488,000 oz platinum, 160,000 oz gold, and 3.05 million oz silver.
• Permitting & Readiness: With all final permits secured in 2025, the project is now shovel-ready, positioning Generation Mining as one of North America’s premier critical mineral developers.

Strategic Land Expansion

• December 2025: Acquired 451 new mining claims in the Marathon District, expanding its land package by 36% to 36,398 hectares.
• This expansion strengthens exploration potential around the Coldwell Complex, opening new targets for copper and palladium discoveries.

Financing & Partnerships

• Previously, the company negotiated a $240 million stream with Wheaton Precious Metals, with C$40 million already received.
• Banking Syndicate Support: In 2025 the company ramped up negotiations Export Development Canada, ING Capital, and Société Générale for up to $540 million in project financing.
• Strong backing from local Indigenous communities, the town of Marathon, and both federal and provincial governments.

Operational & Financial Strength

• Market Positioning: With a market capitalization of ~$200 million versus a project NPV of $1 billion, Generation Mining is seen as a high-conviction growth story in critical minerals.

President and CEO Jamie Levy says “As 2025 comes to an end, Generation Mining has taken major steps toward bringing the Marathon Project to life. Our updated Feasibility Study, completed in March, reaffirmed the project’s potential to become Ontario’s next producing critical minerals mine. In May, we achieved a major milestone by securing the final key permit required for construction of the Marathon Copper‑Palladium Project (“Marathon Project”). With a shovel‑ready plan and strong community alignment, the project is positioned to help supply the minerals needed for a resilient, low‑carbon future. Entering early 2026, we will continue strengthening our leadership team as we move toward final construction decisions.”

Chairman Kerry Knoll says, “All the metrics are in place for a 2026 production financing and construction start at Marathon.”

Holiday Greeting

As 2025 ends, we thank our investors, partners, employees, shareholders and community for their support. This year marked important milestones for Generation Mining, and none of them would have been possible without your trust and collaboration.

May this holiday season bring you joy, rest, and time with loved ones. We look forward to building on our shared successes in 2026 as we continue advancing the Marathon Project and contributing to Canada’s energy transition.
