The U.S. military is partnering with mining companies to secure supplies of critical minerals like germanium and antimony, vital for technologies including semiconductors and munitions. The Pentagon has requested proposals for mining 13 specific minerals by March 20, with potential funding of $100 million to $500 million.

The Department of War announced a $27 million investment in U.S. Antimony Corporation to advance domestic antimony production, which is critical for various defense applications. This investment is part of a broader strategy to strengthen domestic mineral supply chains amid rising geopolitical tensions, particularly following U.S. military actions in Iran.
