United States Antimony (UAMY) said Monday it entered into a formal Metallurgical Testing Agreement with Perpetua Resources (PPTA) to evaluate stibnite-rich material from Perpetua's Stibnite Gold Project in Idaho.
Under the agreement, the company said Perpetua will provide antimony ore samples and assay work for testing at its Montana facility.
The partnership aims to assess potential antimony product specifications that could be commercially produced from Perpetua's ore at its processing plant, the company said, adding that the companies have yet to reach any agreements for joint commercial production.
