$30M Could Unlock $500M in Metal (Ad)

A small exploration company is sitting on an estimated $500 million worth of antimony - a critical defense metal - stockpiled above ground in the Nevada desert. China controls 48% of global production and supplies 63% of U.S. imports, making any domestic source strategically valuable. A $245 million Pentagon contract sent United States Antimony Corporation's stock up 916% in 14 weeks. This company's metallurgical tests show 75%-92% antimony recovery rates using conventional acid leaching, with an estimated $30 million needed to build a processing facility - a potential 16-to-1 value-to-capital ratio. Robert Ross has prepared a full briefing on the project, the stockpile, and the path to near-term production.tc pixel
