Bunker Hill Mining Corp. has provided an update on its progress toward the H1 (first half) 2026 restart of the Bunker Hill zinc-silver-lead mine located in the prolific Silver Valley, Idaho, United States.

Highlights

• Project progress: Construction and commissioning is now 85 per cent complete, and on track for the restart of operations and first concentrate production in June, 2026.
• Processing plant: The mills are turning, with commissioning advancing ahead of plan, complemented by the hiring of new team members.
• Filter plant: One hundred of all mechanical installation completed, with contractors advancing the installation of piping and electrical ahead of schedule.
• Underground preparation: Stockpiles are now sufficient to support the first three months of operations, with development advancing rapidly to encompass all stopes included in the first six months of the mine plan. Plans continue to be optimized, focused on maximizing early cash flow, enhanced by the arrival of the new underground fleet from Caterpillar Inc.
• Exploration restart: Timberline Drilling has been contracted to conduct 25,000 feet of drilling on higher-grade silver targets at Bunker Hill and Ranger Page from April, 2026. This is the first phase of a multiphase drilling campaign to run through 2026.

"As the first signs of spring are seen in the Silver Valley, the Bunker Hill project advances at pace towards its June operational restart. Our team is expanding in size daily, with each new member slotting seamlessly into positions in accordance with our operational readiness schedule," says Sam Ash, president and chief executive officer.

"Even more exciting is the contracting of Timberline Drilling, who will support our exploration team by drilling several high-grade silver targets within both the Bunker Hill and Ranger Page properties beginning in April. This is the initial phase of a multiphase campaign that will continue through 2026 and represents the start of the largest drilling campaign conducted at Bunker Hill since the mine closed in 1981."
