Hycroft Mining confirms metallurgical test results

Hycroft Mining announces results for the Metallurgical Flotation Variability Study. After comprehensive third-party laboratory testing, the Study confirms average flotation recoveries of 89% for gold and 93% for silver, increasing from 80% for both gold and silver in the March 2023 Technical Report1. The increased recoveries were due to modifications to the grind size, reagents and retention time. The results reflect a 20% mass pull into a sulfide concentrate containing 8.5% sulfide sulfur. The variance of the recoveries was +/- 4%. “We are extremely pleased with these results because they clearly demonstrate that we can achieve significant gold and silver recoveries from Hycroft’s sulfide ore,” commented Diane R. Garrett, President and CEO of Hycroft. “The gold and silver flotation recovery results averaged approximately 10% higher than previously modeled with improved flotation consistency across all geologic domains within the projected mine plan.
