70%+ gold and silver recoveries at Teck Hughes
Fulcrum Metals PLC has announced preliminary results from its Teck-Hughes mine tailings project, achieving over 70% gold and silver recoveries using cyanide-free technology, a significant increase from previous figures. The company is extending its leach testing program to assess final recoveries and the potential extraction of gallium and tellurium, with full phase 3 metallurgical results expected in Q1 2026. These positive preliminary recoveries, combined with the current gold price exceeding US$4,000 per ounce, could potentially lead to substantial increases in Fulcrum's previously estimated US$33 million NPV for the Teck-Hughes project.
