Cambria targets late 2027 Premier mill restart

AI desk brief

Cambria Gold is targeting a restart of the 2,500-tpd Premier mill in Q4 2027, with ramp-up through 2028 after the first production attempt failed on insufficient underground feed. The company says $538 million has been spent since 2021, and an updated feasibility study due in H1 next year will set a revised mine plan, production schedule and restart cost.

The restart will initially rely on Premier, Silver Coin and Big Missouri before adding Red Mountain once the access road is complete. Cambria says it now has the final Fisheries Act permit for the Red Mountain road and is still working through major mine authorizations and an EA amendment; it also flagged ongoing water-treatment compliance issues at Premier. Nearby resource bases are material, including Premier’s 1.07Moz indicated and 1.18Moz inferred, plus Red Mountain’s 783koz M&I and 69koz inferred.
