About Cornish Metals Inc.

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

• Is a historical, high-grade, 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 permitted to commence underground mining (valid to 2071) and construct a new processing facility and for all necessary site infrastructure;
• Would be the only primary producer of tin in Europe or North America; tin is a critical mineral as defined by the U.K., 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.
