A Transformational Year for Gunnison Copper
The past year marked a transformational period for Gunnison Copper Corp. (the “Company”), one defined by delivery, discipline, and impactful progress across every level of the Company.
We closed 2024 by releasing the Preliminary Economic Assessment (PEA) for open-pit mining at our flagship Gunnison Project, a critical milestone that reinforced the long-term economic potential of the asset and set the strategic direction for the Company moving forward. That momentum carried directly into 2025.
Early in the year, Gunnison was the only copper mining company selected to receive US$13.9 million in Section 48C tax credits from the U.S. Department of Energy, supporting the expansion of Made-in-America copper production at our Johnson Camp Mine in Southern Arizona. Copper’s designation as a Critical Material underscores the strategic importance of domestic supply, and we are proud to be contributing to that objective as one of the newest U.S. copper producers.
2025 was a year of significant operational achievement at Johnson Camp. In August, the mine commenced pure copper cathode production from run-of-mine oxide material, with the first sale in September, marking our transition from developer to producer. Earlier this month, we achieved first production using Rio Tinto’s Nuton® technology, marking the first industrial scale operation using their bioleaching technology and representing a potentially transformative development for copper production globally. Importantly, we reached first production just over one year after breaking ground, and we did so with zero lost-time accidents, a testament to the operational discipline, safety culture, and professionalism of our team and partners.
We also strengthened our leadership and governance with the appointment of Jason Howe and Joseph Gallucci to the Board of Directors, bringing additional operating and capital markets experience to the Company as we advance our growth strategy.
On the technical front, we delivered positive results from our High-Value-Add (HVA) work program on our flagship Gunnison Project, including advances in mineralized material sorting and limestone by-product evaluation. These initiatives are expected to materially enhance project economics and will be incorporated into an updated PEA, with headline results targeted for the end of January 2026.
We ended the year having repaid all of our non-convertible secured debt, strengthening our balance sheet and positioning the Company with a clear pathway toward becoming fully secured-debt free in 2026. At the same time, interest in Gunnison’s Made-in-America copper story continued to grow, highlighted by a feature in The Wall Street Journal, reflecting broader recognition of the Company’s progress and strategic relevance.
With copper demand and prices continuing to rise and increasing government support for the domestic production of critical minerals, Gunnison is well positioned for continued growth. Over the past 12 months, the Company has delivered strong market-cap appreciation and a substantial increase in trading liquidity, reflecting the achievement of key operational and strategic milestones and the effectiveness of our marketing and investor-outreach initiatives. As we move forward, our focus remains on delivering catalysts, creating shareholder value through consistent execution and expanding on our successful marketing and investor-outreach program globally.
We would like to thank our employees for their dedication, our partners for their collaboration, and our shareholders for their continued support and confidence. The progress achieved over the past year has laid a strong foundation for continued growth in the year ahead.
Sincerely,
The Management Team
