ABOUT CORNISH METALS

Cornish Metals is a mineral exploration and development company that is advancing the South Crofty critical mineral project towards production. South Crofty:

·    is a historical underground tin mine located in Cornwall, United Kingdom and benefits from existing mine infrastructure including multiple shafts that can be used for future operations;

·    is the highest grade known tin Mineral Resource not in production with significant near-mine and regional Mineral Resource potential;

·    is permitted to commence underground mining (valid to 2071), construct a new processing facility and for all necessary site infrastructure;

·    will be a low environmental impact underground mine with zero surface tailings;

·    would be potentially the first primary producer of tin in Europe or North America. Tin is a Critical Mineral as defined by the UK, American, and Canadian governments as it is used in almost all electronic devices and electrical infrastructure. Approximately two-thirds of the tin mined today comes from China, Myanmar and Indonesia;

·    benefits from strong local community, regional and national government support with a growing team of skilled people, local to Cornwall, and could generate over 300 direct jobs;

·    is an opportunity for a secure domestic supply of tin in the UK supporting a low carbon economy.
