Fulcrum Metals plc reported more than 70% gold and silver recovery on preliminary detailed metallurgical work at its Teck-Hughes mine tailings project at Kirkland Lake in Ontario, Canada.
ASSESSMENT
The phase III development work is using Extrakt Process Solutions LLC’s cyanide-free technology to recover metals from mine waste.
Fulcrum said it aimed to optimise leach recovery, tailings dewatering, and pregnant solution recovery for integrating into its operations.
The partners have extended the leach programme to assess final recoveries, and potentially extract other metals such as gallium and tellurium.
Final results from phase III metallurgical testing are expected during the first quarter of 2026.
The results, combined with current auger drilling, will support a 43-101 compliant mineral resource estimate ahead of the phase IV preliminary feasibility study level economic assessment.
