Copper Fox Announces Positive Results from Schaft Creek Metallurgical Program and an Update on 2026 Program

Copper Fox Metals Inc. (CUU) announced positive results from its continuing metallurgical testwork at the Schaft Creek joint venture project. Open circuit cleaner flotation tests indicate that comparable copper and silver recoveries can be achieved at a coarser primary grind size (P80 ~212 µm) compared to historical finer grinds (P80 140-160 µm). Molybdenum and gold recoveries were unaffected or improved at the coarser grind, while copper recovery showed expected variability across feed grades.

Locked cycle tests conducted between 2023 and 2024 support using a coarser primary grind of P80 212 µm as a new baseline, potentially reducing grinding energy and operational costs. The 2026 program focuses on technical reviews to determine readiness for a Pre-Feasibility Study (PFS), including updated geological and metallurgical models, trade-off studies for tailings and mine plans, environmental data collection, camp upgrades, and a BC Hydro System Impact Study.

Schaft Creek remains a joint venture managed by SCJV, with Teck Resources holding 75% as operator and Copper Fox holding 25%.

Copper Fox Metals Inc. (CUU) reported positive but incremental metallurgical results that align with its stated objective to optimize comminution circuits ahead of a Preliminary Feasibility Study (PFS). While coarser grinding could potentially lower future operating expenses, the results remain preliminary and require further optimization, including coarse particle flotation and gold deportment studies, before being incorporated into a PFS model.

The announcement represents a standard technical milestone in the progression toward a PFS, which was already anticipated in prior 2026 work programs. Consequently, the news does not alter the project's valuation or immediate financing needs, with no material deviation from previous expectations.

Copper Fox Metals Inc. is a Canadian junior exploration and development company focused on copper projects in North America. Its flagship asset is the Schaft Creek project, located in northwestern British Columbia, which is considered one of the largest undeveloped porphyry copper deposits in the region and contains significant gold, molybdenum, and silver by-products. Copper Fox holds a 25% carried interest in Schaft Creek via the Schaft Creek Joint Venture, with Teck Resources holding the remaining 75% and acting as operator.

The company also owns 100% interests in several other projects, including the Van Dyke project in Arizona, and the Eaglehead, Sombrero Butte, and Mineral Mountain projects in British Columbia and Arizona. A 2020 Preliminary Economic Assessment for Van Dyke highlighted a 17-year mine life producing 85 million pounds of copper cathode annually, with a post-tax net present value of $644.7 million at a copper price of $3.15 per pound.
