The Berkeley Pit and Discharge Pilot Project (Pilot Project) Discharge System Polishing Facility did not discharge off-site from January 1 through January 31, 2025, and was only operated for maintenance activities during this reporting period. The Polishing Facility continued to operate with all flows directed off-spec to Montana Resources’ dredge pond during the reporting period. Reverse Osmosis (RO) Reject includes flows that were produced during routine permeate flushes; this RO Reject was discharged directly to the Berkeley Pit.
