VANCOUVER, British Columbia, May 09, 2025 (GLOBE NEWSWIRE) -- Cornish Metals Inc.

• Underground mine, including travelling via the mine shaft cage
• Winder House, consisting of a brief on the new Winder

Don Turvey, CEO and Director of Cornish Metals, stated: “We were delighted to have hosted HRH The Princess Royal at South Crofty, it was an honour to show her around the different aspects of the operation. This visit comes at an exciting juncture for the company, following the recent £57.4 million fundraising, including a £28.6 million strategic investment by the UK Government’s National Wealth Fund.

“We are grateful to Her Royal Highness for taking the time to re-open New Cook’s Kitchen Shaft, which is currently being refurbished to allow mine re-entry at lower levels. The opening of NCK shaft is an important milestone as we work to deliver a secure, sustainable, domestic supply of tin in the United Kingdom.

“Tin is classified as a critical mineral in the UK, USA, Canada, and other countries, due to its wide range of traditional uses and its growing role in electronics and energy transition technologies. With no primary tin production in Europe or North America, and Asia controlling over two-thirds of global mine supply and more than 80% of refined tin supply, securing Western sources of tin has become increasingly important. South Crofty represents a unique opportunity to develop a secure, long-term domestic source of tin, reducing reliance on volatile international markets.”
