The project operates as a cost-sharing agreement, with the first 18-month phase requiring an $18 million investment split equally between the government and the company. Funds are earmarked for exploratory drilling, material testing, and the engineering of a decline to reach deeper mineral deposits. Historically, the Stibnite site served as a vital domestic source for tungsten and antimony during World War II.

Perpetua reports that recent drilling campaigns have already uncovered high-grade zones of mineralization at the site. Beyond the tungsten efforts, the firm remains focused on its existing operations beneath the Hangar Flats pit, a deposit currently estimated to contain 1.37 million ounces of gold and over 95 million pounds of antimony.
