U.S. GoldMining Inc.
- Combined flotation and cyanide leach achieved 85.3% Au, 79.1% Cu, 55.3% Ag recoveries.
- Copper concentrate graded 23.7% Cu with 0.6% mass pull; leach recovered additional 31.2% Au from tails.
- Previous metallurgy yielded ~70% Au recovery; new 22% increase due to sequential leach step.
