CORNISH METALS ANNOUNCES INAUGURAL DIGBEE ESG RATING OF A

An independent panel of globally recognized sustainability experts from Digbee has awarded Cornish Metals Inc. an inaugural overall rating of A for both its corporate and project performance.

The Digbee platform offers companies a rightsized, future-looking set of globally aligned sustainability frameworks. Digbee evaluates a comprehensive range of factors, considering both the asset's context and the effectiveness of management actions, to assign a rating from AAA to D. The A score achieved by Cornish Metals is an average of scores received between CCC to AAA.

Extracts from the report:

• ESG (environmental, social and governance) priorities are embedded in the company's strategic planning and governance structures, as evidenced by an internal double materiality assessment, development of a formal sustainability strategy, linkage of ESG KPIs (key performance indicators) to executive remuneration, publication of the inaugural sustainability report, and commitments to preserving the mining cultural heritage and improving biodiversity.
• The company has attracted significant investment from Vision Blue Resources and the United Kingdom National Wealth Fund (together holding over 55 per cent) reflecting strong market and public-sector confidence in its responsible tin production model and long-term alignment with the United Kingdom Critical Minerals Strategy.
• The South Crofty project incorporates underground mining, reuse of existing infrastructure, backfilling of tailings, use of renewable electricity and commissioning of a high-efficiency water treatment plant, demonstrating active efforts to reduce greenhouse gas emissions, surface disturbance and water pollution.

Don Turvey, chief executive officer and director of Cornish Metals, stated: "We are very pleased to share our inaugural sustainability rating from Digbee, which demonstrates the company's commitment to operating to international best practices and acting with transparency. We enjoyed working with Digbee on this and appreciate the comprehensive overview that they have compiled. We understand there is always room for improvement, and we will be taking Digbee's points of feedback on board as we continue to develop our environmental, social and governance practices."

Jamie Strauss, founder and chief executive officer of Digbee, commented: "The successful completion of the Digbee sustainability assessment underscores Cornish Metals' belief that responsible mining is not only the right approach, but a critical differentiator. By embedding responsibility at the heart of its strategy, the company strengthens its social licence to operate and builds trust among all stakeholders -- from communities, regulators and investors.

"Earning an excellent A rating through the Digbee assessment demonstrates the company's significant achievements to date in transparency, environmental stewardship and community engagement. This independent verification not only validates Cornish Metals' current performance but also reflects its clear vision for continuous improvement -- proving that mining can be both a driver of economic opportunity and a trusted partner in protecting and enhancing the communities and environments in which it operates."

About Cornish Metals Inc.

Cornish Metals is a dual-listed mineral exploration and development company (Alternative Investment Market and TSX Venture Exchange) 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), 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., U.S. 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.
