Gunnison Copper unlocks commercial potential in Limestone, transforming waste into valuable product

Proactive - Interviews for investors

Gunnison Copper Corp SVP and CFO Craig Hallworth joined Steve Darling from Proactive to share exciting results from the company’s ongoing High-Value-Add Work Program, which is evaluating the commercial potential of limestone located within the planned Gunnison Open Pit mine in southeast Arizona. The assessment has revealed that a substantial portion of the limestone—currently classified as waste material in the existing mine plan—meets the specifications for a range of industrial end-use markets, including cement production, agricultural lime, and premium paper filler, paint, and coatings applications. Hallworth explained that these findings represent a significant opportunity to generate additional revenue streams from materials previously slated for disposal. “Our initial results suggest strong potential to convert what was once waste into high-value commercial products,” he said. The company plans to expand sampling coverage beyond the initial 883 feet to enhance statistical confidence across the entire open pit area. Upcoming test work will focus on verifying product quality and consistency to meet cement, ag-lime, and premium filler-grade standards. In tandem, Gunnison Copper will explore mine plan optimization and materials-handling trade-offs to identify feasible pathways to market. These efforts will feed into a broader evaluation of logistics, permitting, and commercialization strategies, including potential marketing partnerships and offtake agreements. The insights from this work will be incorporated into the company’s updated Preliminary Economic Assessment, targeted for Q1 2026, and will inform the scope of the forthcoming Pre-Feasibility Study. Hallworth emphasized that this initiative reflects Gunnison Copper’s commitment to maximizing resource efficiency and unlocking hidden value across its asset base. #proactiveinvestors #gunnisoncoppercorp #tsx #gcu #otcqb #gcumf #CopperMining #USMining #CopperProject #CopperMining #GunnisonCopper #NutonTechnology #USMining #CriticalMinerals #CopperProduction #MiningStocks #NaturalResources #ElectricEconomy #CopperPrices #FreeCashFlow #JohnsonCampMine #linstone #steel
