Hycroft Mining Holding Corporation announced 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 Report. 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%. With this phase of the metallurgical test work completed, the bench-top autoclave testwork has been initiated with results expected in the fourth quarter.

The results of the flotation and BTAC metallurgical work will be used to design the Hycroft processing facility for the next phase of commercial operations.
