Bunker Hill Mining Corp.
Bunker Hill Mining Corp. is redeveloping the historic Bunker Hill silver-lead-zinc mine in Kellogg, Idaho (Silver Valley), which ceased operations more than 45 years ago. After six years of redevelopment, the mine moved from construction to ramp-up: on 31 Jul 2026 the company shipped its first concentrate to Teck Resources' Trail Smelter (British Columbia), the mine's first revenue from concentrate sales in over four decades, following commissioning of its 1,800 tpd processing plant. Over 20,000 tons of ore were stockpiled at the crusher as of the announcement, with plans to ramp mining toward the mill's 1,800 tpd design level and about 9 concentrate trucks a day at steady state, and a first production stope blast followed on 17 Aug 2026. Management targets commercial production, which it defines as 90 days above 65% of the 1,800 tpd design throughput, by year-end 2026. On 30 Jul 2026 the company drew $5.0m on a Teck-provided Standby Facility (13.5%/yr interest) with a further $5.0m available, to support working capital through ramp-up. CEO and President is Sam Ash.

Milestones are recorded only from a company's own dated disclosure. A milestone with no date shown is one we can confirm was reached but for which no date was disclosed — we don't estimate one. "Not yet reached" means exactly that, not that a date is missing. An "Expected" line likewise only ever reflects the company's own guidance (e.g. a study or permit decision targeted for a stated quarter) — most not-yet-reached milestones have none, and that absence means no such guidance has been disclosed, not that one is overdue.

Acquisition Susceptibility
A relative ranking of how closely this company matches the profile of juniors that have actually been acquired — not a probability, and not a reason to buy. Acquisitions are rare: only a few dozen significant deals happen a year across a universe of thousands of juniors, so even a high score here describes a long shot. The strongest signal in the research, a producer that already owns part of the company, is scored from its disclosed strategic shareholders. A producer that is a joint-venture or earn-in partner on the project, rather than a shareholder, isn't captured yet.

Reports, Presentations & Documents
Bunker Hill Mining is restarting the historic Bunker Hill silver-lead-zinc mine in Kellogg, in Idaho's Silver Valley, which it owns 100% and which had been closed for more than 45 years. After six years of redevelopment, the company shipped its first concentrate to Teck's Trail smelter on 31 July 2026, its first revenue from concentrate sales, and it is guiding to commercial production, defined as 90 days above 65% of the mill's 1,800 tpd throughput, in the fourth quarter of 2026. Measured and indicated resources, effective 29 August 2022, contain 765,775,000 lb of zinc (254,811,000 lb measured and 510,964,000 lb indicated), plus 688,482,000 lb inferred, with lead and silver as co-products. The 2022 Phase 1 pre-feasibility study shows an after-tax NPV8% of US$52M and a 36% IRR at an average silver price of US$21.70/oz over a 5-year mine life. In August 2026 Bunker Hill agreed to acquire Silver47 Exploration in an all-stock deal valued at about US$163M, after which its own shareholders would own about 57% of the combined company, to be renamed Bunker Hill Silver Corp., with completion expected in November 2026 subject to both companies' shareholder votes.
