Bunker Hill Mining

What Bunker Hill Mining does

Bunker Hill Mining Corp. (TSX:BNKR; OTCQB:BHLL) is a Nevada-registered, SEC-compliant U.S. mining company operating the historic Bunker Hill silver-lead-zinc mine in Kellogg, Idaho, within the Coeur d'Alene Mining District (Silver Valley). The mine produced over 165 million ounces of silver, 3 million tons of lead, and 1.3 million tons of zinc over a 95-year operating history (1885 to early 1980s) before being placed on care and maintenance. Under former Barrick Gold executive leadership installed in 2020, the company repositioned the asset as a modern, ESG-driven brownfield restart anchored by a 3D digitized geological model built from over 3,500 historic drill-holes and hand-drawn maps, and supported by a landmark EPA/Idaho DEQ regulatory arrangement that restructured historical environmental liability. The company is pre-revenue and pre-production, with a target restart in June 2026 at 1,800 tonnes per day and a planned 2,500 tpd expansion underwritten by a U.S. EXIM Bank Letter of Intent for up to US$150 million in debt financing.

The business model is a single-asset, project-financed mining operation. Future revenue will be generated from sales of silver/lead/zinc concentrate to industrial smelters and refiners under offtake arrangements — Teck Resources is the disclosed anchor offtake counterparty and a strategic equity investor — with concentrate pricing tied to prevailing silver, zinc, and lead market prices. Until production restarts, the company is funded by a layered capital stack including a multi-tranche silver loan facility from Monetary Metals Bond III LLC, convertible debentures and a standby facility from Sprott Private Resource Streaming and Royalty Corp., an unsecured promissory note from Teck Resources, a C$52 million bought deal private placement, and a C$33.75 million LIFE Offering of units. The customer base is exclusively institutional: smelters/refiners (post-restart), project financiers, and equity investors. Technology is concentrated in the 3D geologic model, AI-enabled exploration intelligence via VRIFY (a third-party AI platform used for predictive targeting of high-grade silver), and a water treatment system that discharges approximately 1,500 gallons per minute via the Kellogg Tunnel. The company holds Digbee ESG Gold certification and is a member of the U.S. Cornerstone Consortium and U.S. Defense Industrial Base Consortium.

Offtake financing arrangement with Teck Resources underpins future revenue from concentrate sales. Future plans include expanding to 2,500 tpd supported by a proposed $150M US Export-Import Bank debt financing package.
2. Silver Loan Facility (Pre-Revenue Financing): Multi-tranche silver loan facility from Monetary Metals Bond III LLC (with warrants and amendments to extend availability) used to bridge financing toward commercial production restart. Sixth tranche closed at approximately US$2.52 million in November 2025.

Product overview

Bunker Hill Mining Corp. operates a single-asset mining business centered on the Bunker Hill Mine — a historic silver-lead-zinc underground mine in Kellogg, Idaho's Coeur d'Alene mining district — scheduled for a June 2026 production restart at 1,800 tonnes per day. The flagship Bunker Hill Mine anchors the portfolio, complemented by the recently acquired Ranger-Page Silver-Zinc-Lead Project (which expands Silver Valley land holdings) and the active Cate-8 Vein Target exploration program (which targets high-grade silver-lead mineralization in the upper mine area to support near-term production). Supporting these core mining assets are ESG-focused offerings including the Water Quality Tracking Platform and its Kellogg Tunnel Real-Time Data Feed, which provide public-facing transparency on mine water discharge quality. The company also leverages VRIFY's AI-Enabled Exploration Intelligence Software to validate exploration opportunities across its portfolio, representing an integrated combination of physical mining operations, exploration assets, and digital ESG monitoring capabilities.
