Responsibly Sourced Tin for a Low Carbon Economy

Cornish Metals Inc. (AIM / TSX-V:CUSN), is a dual-listed company working towards re-opening its 100% owned, fully permitted South Crofty underground tin mine located in Cornwall, UK. South Crofty is one of the highest-grade tin resources globally with potential to become a new, low-cost global producer. The Company also holds other mineral rights in Cornwall with potential for discovery of tin, copper, lithium, tungsten, zinc and silver mineralisation.

South Crofty has a long history of mining, with over 400 years of recorded production. Existing mine infrastructure, including multiple shafts, can be used for future operations. The Project possesses an underground mining permit to 2071, Planning Permission to construct a new processing plant and all necessary site infrastructure, and an Environmental Permit to dewater the mine. South Crofty benefits from strong local community and regional and national government support.

In January 2025, Cornish Metals announced a fundraising for £57.4 million, anchored by the UK’s National Wealth Fund and existing shareholder Vision Blue Resources demonstrating support for the Company and the South Crofty tin project.

Tin connects almost all electronic and electrical infrastructure, making it critical to the energy transition. It is fundamental to growth in the technology sector and is used in key fast growing technological applications including batteries, robotics, renewable power, 5G and cloud-based data storage. Tin demand is projected to grow by approximately 25% in the next decade.

Tin is a Critical Mineral as designated by the UK, USA, and Canada, and there is no primary tin production in Europe or North America. Approximately two-thirds of the tin mined today is sourced from Asia, mainly from China, Myanmar and Indonesia.

The Company believes that demand for ethically / responsibly / domestically mined tin will continue to increase.
