Capital Metals (LSE:CMET), the developer of the Taprobane mineral sands project in Sri Lanka, has spent 2026 working towards a final Investment decision on its first stage, publishing engineering and cost updates in March. The company remains pre-revenue, and its progress is typical of the development-stage names on the FTSE AIM All Share Index.

What the company does

Capital Metals is a mineral sands developer whose core asset is the Taprobane Minerals Project in Sri Lanka. Mineral sands are a source of titanium feedstock and other heavy minerals. The company is preparing a staged development, with a first stage that would mine and process material before a possible later mineral separation plant.

Project update of 2 March 2026

In an update dated 2 March 2026, the company said engineering studies towards the Stage 1 final investment decision were largely complete, including a fixed lump-sum plant price from Mineral Technologies, an access study and a hydrogeology study. Estimated Stage 1 Capital expenditure fell from US$20.9m to US$17.7m. An environmental impact assessment for the EL199 licence was submitted in December 2025, with a technical review with approving agencies expected in March 2026.

A concept study for a mineral separation plant was under way, targeting a cost estimate of plus or minus 35%, and LSE:CMET had requested about 30 acres in the Hambantota Port district. Construction had started on the first Coastal Regeneration Centre nursery site, and three new appointments were made in Sri Lanka, bringing the site team to 13. Debt and offtake discussions were continuing, with an additional Mining licence and export clarification described as preconditions for financing. The company targeted a final investment decision before the end of the second quarter of 2026, followed by a construction period of nine to twelve months. A webcast for investors took place on 5 March 2026.

Economics and community

LSE:CMET cites a 2022 preliminary economic assessment that gave a project net present value of US$155m to US$235m, and it expects more than 300 direct jobs and over US$150m in government royalties and taxes. Those are company projections, not certainties.

Funding and share issues

As a pre-revenue developer, Capital Metals funds itself through share issues. On 15 June 2026 it announced the issue of 153,595 shares to its broker, Hannam and Partners, in payment of £7,800 of fees at about 5.08p per share, and the grant of 500,000 Options to its technical manager at 5p. Total Share Capital after admission, expected on 18 June, was 492,299,412 shares. Earlier share issues were announced in January and March 2026, and a publication on new national minerals policy followed in February.

Sector and index context

Heavy mineral sands Supply is concentrated in a few countries, and projects in emerging markets depend on licensing and government support. The listed mining sector on AIM is large by company count, and most developers share a reliance on stock markets. The index has a long tail of such companies.

Key risks

The final investment decision was targeted for the end of the second quarter of 2026. Financing, licence approvals and export arrangements are preconditions. Construction costs, Commodity prices and political or regulatory change in Sri Lanka could affect the project, and further share issues may dilute shareholders.

What to watch next

Investors will look for confirmation on the environmental approvals, the additional mining licence, debt and offtake agreements, and a decision on Stage 1. They should consult LSE:CMET's latest announcements to see whether the target date has moved, and watch the share count as funding continues.
