What could change its growth trajectory, and what would confirm it?
With process-plant front-end engineering design complete, Cornish Metals' growth path advances through dated dewatering and pre-production development milestones, and those dates serve as indicators. They support or weaken the case. NCK shaft dewatering is underway, tracking toward the 400-level, approximately 730 metres below surface, in the first half of 2027.
Pre-production development at the 290-level, roughly 530 metres below surface, is timed for 2026's fourth quarter, and the underground drilling programme follows.
Which risks could break the thesis, and what would warn of them?
The financing gap is the risk that would break the thesis for Cornish Metals: the updated preliminary economic assessment raised pre-production capital expenditure to £198 million on scope changes, labour costs, longer dewatering and shaft refurbishment, an extended timeline and cost escalation, while the board recognises a larger debt and equity package than the one raised will be needed to fund development and enable a final investment decision. Delay to that financing or to the final investment decision is the warning sign.
Cornish Metals remains a pre-production company and generated no revenue during the year.
How does it make money per customer, and what is still unknown?
Value capture for Cornish Metals is capital-intensive and deferred: South Crofty is expected to produce about 4,700 tonnes of tin-in-concentrate a year in its first five years of full production at lowest-quartile all-in sustaining costs over an initial 14-year mine life, but £198 million of pre-production capital expenditure is required before any of that output exists, so with no production cost per tonne disclosed the margin it earns cannot be computed.

What does the product do for its buyer, and how is it delivered?
Cornish Metals delivers an underground tin mine returned to production by working towards re-opening its wholly owned and permitted South Crofty underground tin mine in Cornwall, UK.
Cornish Metals holds other mineral rights in Cornwall that are prospective for tin, copper, lithium, tungsten, zinc and silver.
