BNKR Bunker Hill Mining Corp

Bunker Hill Mining Corp. (“Bunker Hill” or the “Company”) (TSX-V: BNKR |OTCQB: BHLL) announces it has been advanced the second tranche, in the amount of US$5 million under the senior secured credit facility (the ”Standby Facility”) with Sprott Private Resource Streaming and Royalty Corp. (“Sprott”), pursuant to which Sprott has agreed to advance up to US$21 million under the Standby Facility, to fund development costs of the Company’s Bunker Hill Mine located in Kellogg, Idaho (the “Bunker Hill Mine”), subject to the satisfaction of certain conditions.

Sam Ash, President and CEO, stated, "As we enter the end of an extremely productive year at Bunker Hill, we are pleased to report the advance of Sprott’s second tranche in the amount of US$5 million and provide an update on our work on-site, particularly in the underground. We have readied five stopes for mining in the UTZ area of the upper mine, near the entrance of Russell Portal, and are close to completing the geotechnical stabilization of the main ramp at it cuts the Cate Fault. Once done, the team will complete the rehabilitation of the ramp down to the 8-2 Level and prepare the chosen stopes on that level for mining."

PROGRESS UPDATE - KELLOGG SITE

Grid Power has now been connected to the processing and associated facilities, enabling, amongst other things, the establishment of outside lighting along the conveyors. Work in the Kellogg Yard continues with the conveyors, crusher tower, concentrate load-out facility and the tailings filter press. While inside the concentrator building, the final installation of the mezzanine floors is completed in anticipation of the placement of the remaining floatation cells. Piping and electrical fitting continues, along with the installation of lubrication systems for the mill.

PROGRESS UPDATE - UNDERGROUND

Operating from the mining base in Wardner, the Company’s underground mining team have nearly completed the stabilization of the ramp as it cuts across the Cate Fault. Once final grouting has been done and power and ventilation reconnected, the teams will recommence with the ramp rehabilitation to the 8-2 Level before preparing stopes there for mechanized long-hole mining.

Closer to the mining base and the Russell Portal and in the UTZ area, the teams have prepared five faces for mechanized cut-and-fill mining whilst concurrently stockpiling underground ore collected during the ramp rehabilitation and associated development work. Essential preparatory work has begun, designed to ensure maximum mine plan optionality during the next commissioning and ramp-up phases of the mine restart.

Further optimization of the mine plan continues alongside ongoing preparation of an updated mineral resource estimate, which the Company plans to issue in Q1 2025.
