Grant Funding Investment At South Crofty Project

Cornish Metals Inc. (AIM/TSX-V: CUSN) ("Cornish Metals" or the "Company"), a mineral exploration and development company focused on advancing its 100% owned and permitted South Crofty tin project in Cornwall, United Kingdom, is pleased to announce that South Crofty's Bartles Foundry project has received grant funding of up to £4,190,500 from the Cornwall and Isles of Scilly Good Growth Programme, which is managed by Cornwall Council and funded by the UK Government through the UK Shared Prosperity Fund ("SPF").

The grant funding is equivalent to a maximum of 62% of the total Bartles Foundry project cost estimated at approximately £6.8 million for the construction of workshops, stores and offices on the Bartles Foundry site. This will support the requirements associated with South Crofty moving to production and includes the cost for the previously announced purchase of 4.5 acres of land from Cornwall Council (see press release dated April 1, 2025). Conditional planning approval for the development was granted in January 2025. This project follows on from the SPF part-funded study in 2024 which concluded that the site was suitable for development.

Don Turvey, CEO and Director of Cornish Metals, stated: "We are delighted to be awarded this grant funding by Cornwall Council, demonstrating ongoing local support for South Crofty and following on from the investment by the UK's National Wealth Fund earlier this year. This funding will enable the construction of the Bartles Foundry project that will support South Crofty as we move into the underground development phase, which will provide local employment opportunities during the construction and operational phase."

Cllr Tim Dwelly, Cornwall Council's Cabinet Member for Economic Regeneration and Investment, said: "South Crofty is a big priority for us. Not only are they supporting high-quality well-paid jobs in the area, they are also helping the security of the whole UK by strengthening the domestic supply of essential minerals. I am proud to support this next step towards bringing tin mining back to Cornwall."
