By 1943, mines across Alaska, including smaller operations like the Gilmer Mine in Vault Creek and the Tok Antimony Project, collectively contributed to a more self-sufficient supply chain. While Alaska's stibnite mines were instrumental during the war, production waned in the post-war years as demand shifted toward new technologies like ...
