07:31 AM EDT, 05/28/2025 (MT Newswires) -- Perpetua Resources ( PPTA ) on Wednesday said it has been awarded up to US$6.9 million in additional funding from the U.S. Army via the Defense Ordnance Technology Consortium (DOTC).

The funding, which builds on the US$15.5 million previously awarded by DOTC two years ago, will be used to test the feasibility of material sourced from Perpetua's Stibnite Gold Project in Idaho to produce military-grade antimony trisulfide, used in certain munitions and advanced defence systems.

The additional funding will enable Perpetua to expand material sampling and to increase the scope and size of the flexible, modular pilot plant, a statement noted.

With the latest funding, Perpetua has now been awarded more than US$80 million by the U.S. Department of Defense.
