Gunnison Copper Secures Funding for Arizona Project
Locales: CANADA, UNITED STATES

Vancouver, British Columbia - February 4th, 2026 - Greenstone Enterprises Inc. (TSXV: GSR) today announced that Gunnison Copper Corp., a key portfolio company, is initiating a secondary private placement offering, signaling strong investor interest in the McCoy-Portland copper project located in Arizona. Sprott Capital Partners Inc. is leading the offering, with additional investment firms also participating, demonstrating confidence in Gunnison's development trajectory.
The McCoy-Portland project is a significant asset, currently estimated to contain 482 million pounds of copper, based on a National Instrument 43-101 compliant Mineral Resource Estimate using a 1.2% copper cut-off grade. This estimate, while substantial, represents only a portion of the potential the project holds. Gunnison is actively pursuing strategies to expand this resource through ongoing drilling programs, alongside advancing a comprehensive feasibility study designed to unlock the project's full economic potential.
The Growing Demand for Copper and Arizona's Promising Landscape
The timing of this funding round aligns with a globally increasing demand for copper, driven primarily by the world's transition to renewable energy and electrification. Copper is a vital component in electric vehicles (EVs), renewable energy infrastructure (solar panels, wind turbines), and energy storage systems. The ambitious climate goals set by various nations are fueling unprecedented demand for this critical metal, and supply is struggling to keep pace. This supply-demand imbalance is expected to continue, creating a favorable market environment for copper producers like Gunnison.
Arizona, in particular, is emerging as a prominent hub for copper mining in North America. The state boasts a rich geological history and a supportive regulatory environment, attracting significant investment in copper exploration and development. While states like Chile and Peru currently dominate global copper production, recent geopolitical instability and logistical challenges in those regions are prompting increased interest in securing domestic supply chains, further bolstering the attractiveness of projects like McCoy-Portland.
Gunnison's Strategy: Resource Expansion & Feasibility Study
The proceeds from this secondary placement will be instrumental in accelerating Gunnison's development plans. A significant portion will be allocated to resource expansion drilling. The current 482 million pound estimate is considered a baseline, and Gunnison believes there is significant potential to increase this figure with targeted exploration. Drilling will focus on identifying extensions of known mineralization and exploring adjacent areas with favorable geological indicators. Positive drill results could dramatically increase the project's overall value and extend its mine life.
The remaining funds will be dedicated to the feasibility study. This crucial study will assess the technical and economic viability of bringing the McCoy-Portland project into production. It will encompass detailed engineering designs, metallurgical testing, environmental impact assessments, and financial modeling. A positive feasibility study is a critical milestone for securing project financing and ultimately, commencing construction. It's expected to detail projected operating costs, capital expenditures, and potential revenue streams, providing investors with a clear understanding of the project's profitability.
Greenstone's Role and the Future of Base Metal Investment
Greenstone Enterprises Inc., as Gunnison's parent company, plays a vital strategic role in supporting its portfolio companies. Greenstone's investment philosophy centers on identifying and nurturing promising mineral resource companies with a focus on base metals. By providing capital and expertise, Greenstone aims to unlock value in these assets and generate returns for its shareholders. Gunnison represents a prime example of this strategy in action.
The company's focus on base metals, like copper, is a deliberate one, recognizing the critical role these materials will play in the future global economy. As demand for clean energy technologies continues to soar, the importance of securing sustainable and reliable sources of base metals will only intensify. Greenstone's investment approach positions it to capitalize on this long-term trend.
