Perpetua Resources, the US Army, and Idaho National Laboratory have launched a new modular mineral processing pilot plant to demonstrate domestic antimony trisulfide production. The facility aims to establish a secure US supply chain for this critical mineral using samples from the Stibnite Gold Project.
Perpetua Resources, the US Army, and Idaho National Laboratory have launched a new modular mineral processing pilot plant in Idaho Falls. The facility is designed to demonstrate the processing of antimony samples from the Stibnite Gold Project to establish a secure domestic supply chain for antimony trisulfide.
Silver Bullet Mines Corp. announced strong antimony results from re-analyzed historical samples at its wholly owned Washington Mine in Idaho. These results, along with elevated lead and zinc values, are expected to add significant value and revenue to the project, which also hosts impressive gold and silver. The company highlights antimony as a critical mineral with high global demand and vulnerable supply chains, with the CEO stating no additional processing is expected for these new commodities.
Bayhorse Silver has reported highly successful selective antimony leaching results, achieving approximately 99.9% removal from its refractory concentrate. This proprietary process is expected to significantly improve the subsequent recovery of silver, copper, and zinc by breaking down the complex tetrahedrite mineral structure.
