Cornish Metals plc (AIM: TIN; formerly Cornish Metals Inc., TSXV: CUSN, redomiciled to the UK effective 16 December 2025) is advancing the South Crofty tin project in Cornwall, one of the highest-grade undeveloped tin resources globally and the last primary tin mine in Europe, targeting restart production by mid-2028. The company also holds the earlier-stage United Downs copper-tin exploration project nearby. Physical construction and dewatering are underway at South Crofty, financed in part by a May 2026 GBP52 million (~US$97M) credit facility from the UK National Wealth Fund and Vision Blue Resources earmarked for underground mine development and shaft refurbishment, surface facilities and infrastructure; as of May 2026 the company's formal final investment decision was still expected in summer 2026. An updated Preliminary Economic Assessment (30 September 2025) is the company's most recent completed economic study.

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.
Not in place: mill. Not yet determined: tailings facility, grid power.
Jurisdiction (40%)9/10
South Crofty sits in Cornwall, UK -- a stable, top-tier-rule-of-law jurisdiction. All underground mining planning permissions (granted by Cornwall Council in 2011/2013, valid to 2071) and environmental water-abstraction/discharge permits are already in place; the company redomiciled from a Canadian entity (Cornish Metals Inc., TSXV:CUSN) to a UK plc effective 16 December 2025, delisting from TSXV and now trading solely on AIM as Cornish Metals plc.
Infrastructure (40%)5/10
No confirmed mill and confirmed road access at South Crofty Tin Project, Cornwall, United Kingdom; grid power and tailings facility not yet researched, counted at a neutral 5/10 until established.
Nearby producing mine (20%)Not yet researched
No producing mine within 50 km in our reference list (nearest listed: El Valle-Boinas (Orvana Minerals Corp.), 776 km). That list doesn't cover every mining district yet, so a longer distance isn't scored as remote.
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.
