Imperial Secures Mount Polley Permit, Details Q2 Production, and Uncovers Huckleberry Molybdenum
Anonymous
Imperial Metals Corporation has secured a key environmental permit for its Mount Polley mine in British Columbia, while reporting Q2 2026 copper and gold output of 3.382 million pounds and 6,848 ounces respectively, according to Globe Newswire. The British Columbia Environmental Assessment Office recommended approval for a new tailings dam at the 987-metre level, clearing a critical regulatory hurdle for the operation.
Production in the quarter drew from three sources: 44% from the Springer pit Phase 5 pushback, 15% from the Phase 4 and C2 pit, and 41% from lower-grade stockpiles, Brantford Expositor reported. That heavy reliance on stockpile material pushed copper grades down while gold grades ran higher than normal.
Tailings Dam Permit Clears Path for Continued Operations
The BC Environmental Assessment Office recommended approval of the Mount Polley Tailings Dam construction at the 987-metre elevation, Montreal Gazette reported. This permit is a significant step for Imperial, as tailings management has been a sensitive issue at Mount Polley since a dam breach in 2014. Securing this approval removes a major regulatory barrier to continued mining.
Imperial has not yet disclosed a full construction timeline for the new dam structure. The permit recommendation signals that regulators are satisfied with the company's current plans. Operations at Mount Polley have continued in the years following the 2014 incident under strict environmental oversight.
Low-Grade Stockpiles Drag Copper Output, Boost Gold
The decision to run large volumes of low-grade stockpile material through the mill shaped the entire Q2 production profile, according to Toronto Sun. Low-grade ore naturally carries less copper per tonne. Running 41% of mill feed from stockpiles meant copper recovery suffered, while gold — which behaved differently in the ore mix — came in at higher grades.
Imperial says three separate initiatives are underway to lift grades in Q3 2026, Daily Herald Tribune reported. One key move is the development of the Boundary pit — a small, high-grade open pit designed to deliver richer feed directly to the mill. The company has not yet released specific grade targets for the third quarter.
Boundary Pit and Springer Pushback Set to Lift Q3 Grades
The Springer pit Phase 5 pushback was the single biggest contributor to Q2 output at 44%, Stratford Beacon Herald reported. A pushback is when miners strip away the outer wall of an open pit to expose deeper, often higher-grade ore below. Phase 5 work is ongoing and is expected to deliver better ore quality as it advances deeper into the deposit.
The Boundary pit development is the most targeted grade-improvement effort. It is a smaller pit being built specifically to add high-grade copper feed to the mill blend, Cochrane Times Post reported. Blending high-grade Boundary ore with stockpile material should raise average mill grades and improve copper recovery in the months ahead.
Huckleberry Drilling Finds Strong Molybdenum Mineralization
At the Huckleberry mine, Imperial completed 22 NQ core-size diamond drill holes as part of its 2026 exploration program, Financial Post reported. The holes targeted an extension of the Main zone and tested ground below a molybdenum trend identified in historic drilling. Molybdenum is a metal used to harden steel and commands significant industrial demand.
Results showed strong molybdenum mineralization along the contact zone between rock types, according to Financial Post. This is an early-stage finding, but it suggests the Huckleberry deposit may extend further than previously mapped. Imperial has not yet announced plans for a follow-up drill program or resource estimate update based on these holes.
