Cornish Metals Releases Unaudited Financial Statements and Management’s Discussion and Analysis for the Three Months Ended 31 March 2025

VANCOUVER, British Columbia, May 15, 2025 (GLOBE NEWSWIRE) — Cornish Metals Inc. (TSX-V/AIM: CUSN) (“Cornish Metals” or the “Company”), a mineral exploration and development company focused on advancing its 100% owned and permitted South Crofty tin project in Cornwall, United Kingdom, is pleased to announce that it has released its unaudited financial statements and management, discussion and analysis (“MD&A”) for the three months ended March 31, 2025. The reports are available under the Company’s profile on SEDAR+ (www.sedarplus.ca) and on the Company’s website (www.cornishmetals.com).

Highlights for the three months ended March 31, 2025 and for the period ending May 14, 2025

(All figures expressed in Canadian dollars unless otherwise stated)

• Strategic investment and fundraise (the “Fundraise”) (news releases dated January 28-31, 2025):
  • The Fundraise totalling £57.4 million announced on January 28-31, 2025 was anchored by the National Wealth Fund Limited (“NWF”) and Vision Blue Resources Limited (“Vision Blue”), investing £28.6 million and £18.1 million, respectively, with a further £10.7 million from existing shareholders and new investors, including £1.4 million from a retail offer;
  • The Fundraise is expected to provide financial runway through to the end of Q1 2026 and will enable the Company to further de-risk South Crofty and advance it towards a formal final investment decision;
• Senior management appointments (news release dated April 27, 2025):
  • Strengthening of the project and operations teams at South Crofty with the appointments of Dave Howe as General Manager and Guillermo Alcaraz as Project Director;
  • Mr. Howe has 35 years of open pit and hard rock underground mining (including narrow vein) operational and exploration experience, of which 24 years were in executive and senior management roles;
  • Mr. Alcazar is a project executive with over two decades of global experience leading and overseeing a multimillion-dollar complex portfolio of mining, heavy industrial and infrastructure projects across diverse development stages;
• Purchase of 4.5 acres of land from Cornwall Council (news release dated April 1, 2025):
  • The purchased land is immediately adjacent to existing surface land owned by Cornish Metals and provides direct access to the main road at Dudnance Lane from where a new entrance to the mine site is planned and where a new mine office, stores and workshop will be located.
• Mine dewatering and refurbishment of New Cook’s Kitchen Shaft:
  • Refurbishment of New Cook’s Kitchen shaft (“NCK”) is progressing and has reached approximately 290 metres below surface. The water level in NCK shaft is currently at approximately 300 metres below surface;
  • Progress during the period under review has been slower than in prior periods reflecting the staged maintenance of the submersible pumps in preparation for the next phase of dewatering. Dewatering is currently advancing at a rate of over 15,000 m³ per day and this will increase to approximately 25,000 m³ per day once maintenance is completed.

Don Turvey, CEO and Director of Cornish Metals, stated: “We started the year on a strong note successfully completing the £57.4 million fundraise that was supported by existing and new shareholders, including Vision Blue and the UK’s National Wealth Fund. This funding will enable the Company to maintain its strong momentum and further unlock South Crofty’s potential by delivering important milestones expected in the coming year including advancing mine dewatering and shaft refurbishment, placing orders for long-lead items, the start of early project works and concluding the project finance process. We have also strengthened our project and operations teams at South Crofty with senior appointments to the roles of Project Director and General Manager who will be key to leading South Crofty through successful construction and to full production.”

Financial highlights for the three months ended March 31, 2025 and March 31, 2024

• Operating expenses have risen reflecting increased professional fees associated with more corporate activity as well as an increase in corporate remuneration due to bonuses following completion of the Fundraise;
• Project related expenditure of $5.3 million relating to the advancement of South Crofty, primarily relating to NCK shaft re-access & refurbishment, preparation for the refurbishment of the pump station at 360 metres depth and ongoing project engineering studies;
• Dewatering costs of $1.5 million for power, reagents, sludge disposal and maintenance of the water treatment plant (“WTP”);
• Receipt of $87.5 million in net proceeds from the Fundraise after repayment of the debt facility with Vision Blue which was settled through a set-off with the Fundraise; and
• Cash increased by $78.7 million to $89.0 million at the period end due to the proceeds received from the Fundraise offset by ongoing development activities at South Crofty.

Outlook

As described above, the Company continues to advance and derisk South Crofty towards production. The Company’s near-term objectives are as follows:

• Complete dewatering of South Crofty mine and refurbishment of NCK shaft;
• Advance detailed project engineering studies;
• Place orders for long lead items of plant and equipment;
• Commence early project works, including initial construction of the groundworks for the processing plant; and
• Arrange project financing for South Crofty.

ABOUT CORNISH METALS

Cornish Metals is a dual-listed mineral exploration and development company (AIM and TSX-V: CUSN) that is advancing the South Crofty tin project towards 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;
• has a 2024 Preliminary Economic Assessment that validates the Project’s potential (see news release dated April 30, 2024 and the Technical Report entitled “South Crofty PEA”):
  • US$201 million after-tax NPV_8% and 29.8% IRR
  • 3-year after-tax payback
  • 4,700 tonnes average annual tin production in years two through six
  • Life of mine all-in sustaining cost of US$13,660 /tonne of payable tin
  • Total after-tax cash flow of US$626 million from start of production
• would be the only 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 up to 320 direct jobs.

The 2024 Preliminary Economic Assessment for South Crofty is preliminary in nature and includes Inferred Mineral Resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorised as Mineral Reserves. There is no certainty that the 2024 Preliminary Economic Assessment will be realised. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.
