Gunnison Copper (OTCQB: GCUMF, TSX: GCU) promoted Robert Winton to Chief Operating Officer effective October 9, 2025. Winton, with more than 25 years of mining experience, guided the Johnson Camp Mine restart from care-and-maintenance to first copper production and commercial sales in 2025.

As COO he will oversee site operations, project development, and upcoming work programs, and continue coordination with Nuton LLC (a Rio Tinto venture) where first copper via advanced bio-leaching is expected later in 2025. The promotion follows Johnson Camp reaching production within one year of breaking ground.

Gunnison Copper (OTCQB: GCUMF) released preliminary results of a University of Arizona economic impact study dated October 8, 2025, estimating a $14.6 billion cumulative present‑value output across the U.S. over the life of the Gunnison Project. The study forecasts 53,521 job‑years and $2.07 billion in labor income nationally, with $10.01 billion output in Arizona and $9.02 billion in District 6 (including Cochise County).

The release notes average annual direct revenue of $625 million and combined national annual output of $1.43 billion. The company cautions these are forecasted impacts contingent on feasibility, financing and permitting. The company also announced an initial $500,000 Nebari conversion at US$0.2097, issuing 2,384,358 common shares and reducing the Second ARCA principal.

Gunnison Copper Corp. (OTCQB: GCUMF) has achieved a significant milestone with its first copper sales from the Johnson Camp Mine (JCM) in Arizona. The company sold 225,371 pounds of copper cathode at US$4.64 per pound, generating gross proceeds of US$1,046,194.

The mine, which began production in late August 2025, has a nameplate capacity of 25 million pounds of copper cathode annually. The facility will implement Nuton's bio-leaching technology later this year, marking the first large-scale deployment of this innovative Rio Tinto venture. JCM's production contributes to domestic supply chains, supporting American energy independence and manufacturing sectors.

Gunnison Copper (OTCQB: GCUMF) has signed a non-binding Letter of Intent with Lunasonde Inc., a defense technology start-up, to test innovative airborne subsurface imaging technology for mineral exploration. The partnership will focus on exploring Gunnison's district-scale land package in southeastern Arizona's Cochise Mining District for copper, critical minerals, and rare earth elements.

The collaboration aims to leverage Lunasonde's experimental Airborne Georadiotomography (aGRT) technology to identify new mineral targets beneath thick alluvial cover. The parties plan to seek funding through the U.S. Department of Energy's ROCKS Program. The district is known to potentially host at least 12 critical minerals important to the US supply chain.

Gunnison Copper (OTCQB: GCUMF) reported positive results from its mineral sorting test program at the Gunnison Copper Project in Arizona. The tests demonstrated a significant 75% reduction in acid consumption while maintaining copper recovery rates. Testing on Martin Formation samples, which comprises 44% of the resource base, showed that over 90% of internal acid-consuming waste was successfully removed using optical mineral sorting.

Key results include: 57% of the sample sorted to mineralized material with 0.62% total copper content, while 43% sorted to waste with minimal copper loss. The process could potentially remove about 40% of mined Martin Formation as waste, effectively doubling the process head grade and reducing operating costs. The company plans to incorporate these results into an updated preliminary economic assessment expected in Q1 2026.
