Bunker Hill Mining Corp.
Bunker Hill Mining Corp. was incorporated in 1997, acquiring the historic Bunker Hill Mine in Kellogg, Idaho, which ceased operations in 1981 after decades as one of America's largest lead and zinc producers. The company, headquartered in Toronto with operational assets in Idaho, is led by CEO Sam Ash, who took the role in 2019 following a career in mining finance and restructuring. The firm's strategy centers on dewatering and rehabilitating the underground mine to extract silver, lead, and zinc — three metals essential to electrification and battery supply chains. Production targets rely on the mine's existing but untapped reserves: a 2023 prefeasibility study outlined a 5.5-year mine life with annual payable metal production averaging 11.2 million ounces of silver equivalent. Bunker Hill plans to use on-site processing and has signed offtake agreements with Teck Resources' Trail smelter. The focus is exclusively on this single asset, with no diversified project pipeline. As of 2024, Bunker Hill has raised roughly $67 million in equity and $26 million in a non-dilutive loan through the Idaho State Bond Bank to fund Phase 1 construction (per public filings, 2024). The firm listed on the TSX Venture Exchange in 2020 and later cross-listed on the OTCQB in the United States. January 2024: Closed a marketed public offering for gross proceeds of approximately $7.4 million to accelerate mine restart activities and working capital (per the firm, January 2024). The company's professional and board network draws heavily from Canadian mining finance and operational turnaround specialists. Bunker Hill's structural differentiator is its position as a publicly traded revival play on a single legacy asset in a reliable mining jurisdiction. Unlike a traditional family office or diversified mining conglomerate, it channels public market capital into a single brownfield restart, making its returns path binary. Its governance structure and management incentives are tied entirely to achieving first concentrate production — targeted for late 2024 — after which it transitions from a developer to a producer.

Frequently asked questions
What is Bunker Hill Mining Corp.'s core asset?
The company's sole material asset is the Bunker Hill Mine in Kellogg, Idaho — a historic underground mine that produced lead, zinc, and silver for nearly 90 years before closing in 1981. It is currently being dewatered and rehabilitated for a restart. The mine sits on patented claims in the Coeur d'Alene Mining District.
Who makes investment decisions at Bunker Hill Mining?
CEO Sam Ash leads capital allocation and strategic decisions. Prior to joining Bunker Hill, Ash held senior roles at resource-focused investment firms including Endeavour Financial. The board, chaired by Richard Williams, includes members with backgrounds in mining operations and institutional finance.
Does Bunker Hill Mining participate in fund commitments or only direct development?
Bunker Hill does not commit capital to external funds. All capital is directed toward a single direct development: the Bunker Hill Mine restart. The company functions as an operating entity, not a diversified investment vehicle. It raises capital through equity and debt offerings to fund construction and working capital.
What metals does Bunker Hill target and why?
The mine's orebody contains silver, lead, and zinc. These metals are critical to energy transition infrastructure — including batteries, solar panels, and grid storage. The company has positioned its restart narrative around supplying US-sourced critical minerals to domestic smelters.
How is Bunker Hill Mining structured as a public company?
Bunker Hill trades on the TSX Venture Exchange (ticker: BNKR) and the OTCQB in the United States. It is not a family office or private partnership — it is a publicly held development-stage mining company. Retail and institutional investors can access its equity through standard brokerage accounts.
How does Bunker Hill source offtake for its production?
In 2022, Bunker Hill signed concentrate offtake agreements with Teck Resources' Trail smelting complex in British Columbia, covering zinc and lead production. The proximity of the Trail facility — roughly 150 miles from the mine site — reduces transportation costs and provides a known processing route in a stable jurisdiction.
What is Bunker Hill's known posture on co-investments or joint ventures?
The firm has not disclosed a formal co-investment program. It has, however, utilized non-dilutive state-level financing: in 2023, it closed a $26 million loan through the Idaho State Bond Bank, a mechanism that allows public-entity financing for projects that create local economic benefit without giving up equity.
