Americas Gold and Silver Corporation announced promising results from recent metallurgical testing at its Galena Complex in Idaho, confirming high recoveries of antimony alongside strong silver and copper recoveries from ore currently being processed. Test Highlights: Antimony Recovery: 90 - 96% from ore grading 1% Antimony; Silver Recovery: 98 - 99% from ore grading 50 opt Silver; Rougher Concentrate Grades: 18 - 19% Antimony and 600 opt Silver. These test results on the tetrahedrite material indicate that a marketable concentrate may now be possible using modern metallurgical processes.

The results from the test work are shown in Table 1 below. The antimony (Sb) distribution calculation uses the assay head grade to determine distribution. The test results mark a key step toward establishing Americas Gold and Silver as the only current antimony producer in the United States, unlocking a new revenue stream from a strategic by-product, previously counted as a penalty element, of the Galena ore body.
