Bunker Hill Mining Company (Bunker-TSX, BHL-OTCQB) It is on track to restart its flagship Bunker Hill Mine in June 2026, which is located in the Coeur d’Alene mining district in northern Idaho.
The company said it continues to make strong progress across all key workstreams as it progresses towards the restart, with approximately 93% of pre-production activities completed. “Underground development work, infrastructure readiness, and equipment commissioning are progressing as planned, with the support of our operations team and existing contractor base,” the company said in a press release. These developments place Bunker Hill in a controlled transition to steady state operations, she said.
The Bunker Hill renewable mine is expected to be a low-cost, long-life and sustainable project, the company said.
The pre-feasibility study envisions an initial mine life of five years, generating $25 million in annual cash flow. Capital expenditures are pegged at $55 million over 16 months.
In a recent update, the company said that the 1,800 tons per day processing facility building and its motor control center have been fully constructed and connected to the 13.8 kV electricity grid. She said internal construction activities, enabled by the 20-tonne operational internal crane, focused on placing the fully refurbished mezzanine floors, flotation cells and associated mechanical equipment.
On Monday, Bunker Hill shares fell 0.84%, or $0.05, to $5.90. Shares are trading in a 52-week range of $10.32 to $3.675.
Meanwhile, Bunker Hill announced preliminary results from the ongoing underground exploratory drilling program at the “Cate-Eight” target at Bunker Hill. This underground exploration program is designed to test high-grade silver targets close to recently constructed mine infrastructure in the upper zone of the mine, with the potential to be incorporated into the near-term production plan.
Exploration highlights include drill hole BHE26-01, which intersects new veins with high-grade silver-lead mineralization close to existing underground mine infrastructure. It returned 2.3 feet at 11.1 oz/t silver and 28.4% lead, in the wider vein area 3.5 feet thick, returning 7.92 oz/t silver and 20.55% lead.
These veins have not been extracted or identified by previous exploration work conducted at Bunker Hill.
Mineralization occurs 40-120 feet from mine development and remains open to expansion in all directions. The current exploration target extends 350 feet along strike and 450 feet upstream, highlighting exploration opportunities in the unexplored upper areas of the mine, close to the footprint of existing mine infrastructure, the company said.
“The program has just begun and is on track,” the company said, adding that 730 feet of the planned 25,000 feet campaign had been drilled.
The “Cate-Eight” vein target is considered to belong to the silver-rich Galena-Quartz (GQ) series of veins, which were previously mined in the lower levels of the Bunker Hill Mine. This group of veins has historically been unexplored and largely unexploited in the upper levels of the mine and represent attractive targets for exploration of high-grade silver adjacent to the mine infrastructure, the company said.
