Gunnison Copper Accelerates District-Wide Drill Program, Preparing for Six-Rig Expansion and Upcoming Preliminary Metallurgical Results
Gunnison’s routine drill progress update aligns with guidance, offering no new catalysts or valuation inflection for the project.
Gunnison Copper Corp. (GCU) provided a progress update on its US$15 million district-wide drill program at the Gunnison Copper Project and the Strong & Harris satellite deposit in Arizona. Metallurgical optimization drilling is 30% complete, comprising 7,950 ft across 7 holes. All Gunnison metallurgical drilling has been finished, and work is now focused on Strong & Harris.
Resource expansion and exploration drilling remains at 0%, with 0 holes completed against 84 planned, as the program phases sequentially from metallurgical to resource work. Column leach tests have increased to 405 from 270, with 68 currently in process. Additionally, 63 flotation tests were added for sulfide recovery.
A new core logging and storage facility is nearing completion, enabling a rig count expansion from two to six in September. Preliminary metallurgical results are expected in Q4 2026, with full results targeted for mid-2027.
Gunnison Copper Corp. (GCU) released a routine operational update confirming the company remains on track with its previously announced US$15 million drilling program. The announcement contained no new financial results, guidance changes, or unexpected operational milestones.
The market’s reaction, with the stock trading flat at $0.46 following the Aug 13 earnings release, indicates the update was fully telegraphed and priced in. The news carries no material impact on valuation or near-term catalysts, serving only to validate the existing Preliminary Feasibility Study (PFS) timeline and metallurgical work program.
Gunnison Copper Corp. operates two primary assets in Arizona's Cochise Mining District: the producing Johnson Camp Mine (JCM) and the development-stage Gunnison Copper Project. The JCM is fully funded by Nuton LLC, a Rio Tinto venture, and utilizes proprietary bioleaching technology to produce copper cathode with a significantly lower carbon footprint than conventional methods.
The Gunnison Project is a conventional open-pit, heap-leach, SX/EW operation planned to produce 174 million lbs of copper annually, featuring a direct rail link and integrated cement/limestone by-product sales. The company has secured strategic partnerships with AWS, identified as the first customer for Nuton copper, and joined the U.S. Defense Industrial Base Consortium (DIBC), reinforcing its domestic supply chain positioning. Management, led by CEO Craig Hallworth, brings extensive Arizona mining and construction finance experience, having previously worked on Hudbay's Copper World and Mason projects.
