A US federal court has upheld key environmental approvals for Perpetua Resources’ US$1.3‑billion Stibnite gold‑antimony project in Idaho, allowing early works to continue while an appeal proceeds and a final investment decision is targeted for this year. Stibnite is designed to produce about 463,000 oz. of gold annually in its first four years and hosts 43.5 million indicated tonnes grading 1.07 g/t Au and 0.07% Sb, backed by a US$2.9‑billion EXIM loan and Department of Defense support for domestic antimony supply. Current activity includes fabrication of two autoclaves in Europe, completion of grading and utilities for the permanent camp, and a 10,000‑metre, four‑rig drill programme chasing additional gold‑antimony‑tungsten resources around Yellow Pine, Huckleberry and Hangar Flats.
