Gunnison Copper nears first Copper sales as SX-EW plant comes online at Johnson Camp Mine

Gunnison Copper Corp Senior Vice President of Operation Robert Winton joined Steve Darling from Proactive to announce the start-up of the solvent extraction (SX) plant and electrowinning (EW) circuit at the company’s Johnson Camp Mine in southeast Arizona, with first copper sales expected in September. Construction activities at JCM, funded by Nuton LLC, a Rio Tinto venture, remain on schedule. The final phase of leach pad construction is progressing as planned, while the on-pad crushing circuit, designed for use with Nuton Technologies, has been installed and entered commissioning. The agglomerator and related processing equipment are in place, with final mechanical and electrical construction nearing completion. Additionally, the new LNG system at the EW plant has been fully commissioned and is operating in line with the start-up of electrowinning. Winton said that starting the SX-EW plant ahead of schedule marks another major step toward achieving targeted copper cathode sales in September 2025. Looking ahead, Gunnison Copper said focus will shift toward the Gunnison Project. The company reported that the project carries a net present value of between $1.30 billion and $1.40 billion. It said efforts are underway to increase that value by commercializing gravel and 85.00 million tons of high-grade limestone from the site. It also reported that ore sorting trials are being conducted to separate acid-consuming rock that does not contain copper. The company said this process, already used successfully in other operations, could significantly improve recovery rates and add value to the preliminary economic assessment released in November 2024. #proactiveinvestors #gunnisoncoppercorp #tsx #gcu #otcqb #gcumf r #CopperMining #USMining #CopperProject #MiningInvestment #CommodityMarkets #CopperProduction #ArizonaMining #ResourceDevelopment #MiningStocks #CopperDemand #MetalsAndMining
