On April 30, 2024, the Bunker Hill Mining Co. received its critical Pre-Permit to Construct from the Idaho Department of Environmental Quality (IDEQ), allowing the company to start construction of its processing, and associated tailings management and mining facilities at the Bunker Hill mine near Kellogg, Idaho. This essential permission was granted following a detailed review of the company’s air emissions model and all of the associated controls.

Construction activities are now underway, and Bunker Hill hopes to begin technical commissioning of the plant during Q4 2024. “The start of our processing plant construction represents a vital and exciting milestone in our journey to restart the Bunker Hill mine.” said Sam Ash, CEO, Bunker Hill Mining. “We are on track for the planned start of both mining and mill commissioning by the end of this year, with the goal of ramping up to full production through Q1 2025.”

After completing a detailed review of the restart plan, Bunker Hill said it elected to optimize the tailings filtration plant design to ensure both the highest possible standards of long-term environmental management and the ability to ramp up operations from 1,800- 2,500 metric tons per day over time.

This final design favored the more effective, but more expensive, pressure filtration system over the disk filter method considered in the company’s preliminary feasibility study. The company said engineering for the new filtration plant has passed the 60% engineering milestone; with construction of the foundations intended to start in June 2024 following the setting of the deep piers.
