Lunasonde Completes Airborne Survey, Advancing High-Priority Exploration Target Generation at Gunnison Copper's Cochise Mining District
Gunnison Copper Corp.

Executive Summary
- Lunasonde Inc. completed an airborne survey (aGRT) across the Cochise Mining District to identify copper-bearing structures; data processing is underway with initial results expected in the near term.
- Gunnison Copper Corp. entered a buyback option agreement with Altius Royalty Corporation and Triple Flag entities to reduce royalty obligations contingent on a Change of Control transaction by March 31, 2028.
- The buyback package costs US$65 million if exercised; it reduces Triple Flag gross revenue royalty from 3.0% to 2.0% and Altius royalty by 0.5%.
- The agreement includes the right to terminate Triple Flag's expansion option at the Gunnison Copper Project upon exercise.
Material Impact
- Exploration Update: The completion of the airborne survey is incremental progress but does not yet provide new drill targets or resource estimates; this is a standard step in exploration rather than a material value driver compared to the February 2026 PEA.
- Royalty Buyback: The royalty reduction improves long-term margins (1% gross revenue reduction) but is contingent on a Change of Control transaction announced by March 31, 2028; without an M&A event, this value remains theoretical and does not impact current cash flow or balance sheet.
- Context vs. History: This news follows the February 2026 PEA (NPV $2B) and January 2026 debt elimination; it serves as maintenance rather than a fundamental shift in investment thesis, explaining the lack of immediate market reaction potential.
