[Americas Gold and Silver Achieves Breakthrough in Antimony Recovery in the US, Aims to Restart Local Strategic Metal Capacity] On May 15, Canadian miner Americas Gold and Silver announced that its Galena mine in Idaho, the US, had recently completed beneficiation and metallurgical tests, demonstrating an antimony recovery rate of over 90%, with associated silver and copper recovery rates also exceeding 98%. Historically, the project has produced over 18 million pounds of antimony (approximately 8,165 mt), but this has not been monetized due to quality constraints. This technological breakthrough is expected to position the company as the sole antimony producer in the US and unlock new revenue streams from strategic minerals. In the next phase, the company will accelerate process optimization to achieve commercial-scale production. Antimony is currently classified as a critical mineral by the US and is widely used in defense, batteries, and semiconductors, with over 90% of its supply relying on imports.
