Review of activities

Strategic investment and fundraise

On January 28-31, 2025, the Company announced a Fundraise totaling £57.4 million that was anchored by NWF and Vision Blue, investing £28.6 million and £18.1 million, respectively. A further £10.7 million was raised 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 enables the Company to further de-risk the South Crofty tin project and advance it towards a formal final investment decision by:

• bringing the South Crofty tin project nearer to production by funding certain elements of the South Crofty tin project's initial capital expenditure requirements;
• commencing early project works, including initial construction of the groundworks for the processing plant;
• placing orders for long-lead items of plant and equipment; and
• advancing detailed project engineering studies.

Grant funding investment

South Crofty's Bartles Foundry project received grant funding of up to £4.2 million from the Cornwall and Isles of Scilly Good Growth Programme, which is managed by Cornwall Council and funded by the UK Government through the UK Shared Prosperity Fund. The grant funding is equivalent to a maximum of 62% of the total Bartles Foundry project cost estimated at approximately £6.8 million for the construction of workshops and stores on the Bartles Foundry site. This will support the requirements associated with South Crofty moving to production and includes the cost for the purchase of 4.5 acres of land from Cornwall Council mentioned further below (refer news release dated June 11, 2025). The first claim in the amount of approximately £0.7 million was submitted to the Council in late July and is expected to be received by the end of August 2025.

Key long-lead item orders

Orders have been placed with Qualter Hall for the design, manufacture, supply, installation and commissioning of the production and service winders to be used at South Crofty's NCK shaft. The two winders are long-lead items and constitute an important use of proceeds from the fundraise completed in March 2025.

Mine dewatering and refurbishment of New Cook's Kitchen Shaft

Mine dewatering has resumed near full capacity following completion of staged maintenance of the submersible pumps that resulted in reduced pump availability and delays in the servicing one of the pump motors. Refurbishment of NCK shaft is progressing well with advance rates back in-line with the plan for mine dewatering.

The mid-shaft pump station at approximately 360 metres below surface has been reached. Securing the work area and stabilising of the underground chamber of the pump station, enabling the installation of new permanent pumps, has commenced. Shaft refurbishment and mine dewatering will continue in parallel with this work, down to the current level of the submersible pumps at approximately 380 metres below surface.

Work on the pump station is expected to be completed during Q4 2025. The submersible pumps will then be lowered to the lower pump station level (approximately 730 metres below surface) and mine dewatering and shaft refurbishment will resume at that point. Mine dewatering and NCK shaft refurbishment to the lower pump station level are expected to be completed by mid-2026.

Start of surface works at South Crofty

The first major phase of surface redevelopment at South Crofty started in early July with refurbishment of the Mine Dry building and demolition of the old Bartles Foundry buildings. Excavation and earthworks for the processing plant are expected to commence in August 2025.

Senior management appointments

On April 27, 2025, the Company announced the appointments of Dave Howe as General Manager and Guillermo Alcazar as Project Director, strengthening the project and operations teams at South Crofty as the project transitions to construction and development.

Mr. Howe has 35 years of open pit and underground hard rock mining (including narrow vein) operational and exploration experience, of which 24 years were in executive and senior management roles. He has experience in rehabilitation of old previously operating wet mines, including drilling, dewatering and developing them back into successful operation, and has also managed different narrow vein mines.

Mr. Alcazar is a project executive with over two decades of global experience leading and overseeing multimillion-dollar complex portfolios of mining, heavy industrial and infrastructure projects across diverse development stages.

The Company also announced that Owen Mihalop, Chief Operating Officer, left the Company with effect from April 25, 2025 in order to pursue new opportunities.

Land purchase from Cornwall Council

On April 1, 2025, the Company announced the purchase of a 4.5-acre land parcel from Cornwall Council that is immediately adjacent to South Crofty surface infrastructure. The land purchase provides direct access to the main road at Dudnance Lane where a new entrance to the mine site is planned and where new mine workshops and stores will be located. This acquisition increased the total land area at South Crofty owned by the Company to approximately 32.5 acres.

Sale of North American assets

Mactung and Cantung royalties : the deferred consideration of US$1.5 million was received from Elemental Altus on July 23, 2025.

Nickel King property : on July 30, 2025, the Company received the final cash payment of $250,000 from Northera, resulting in the agreed aggregate cash consideration of $500,000 being received in full. The Company will transfer the Nickel King property to Northera upon finalisation of a definitive sales agreement. Upon completion of a go-public transaction by Northera, resulting in a listing of securities on the TSX Venture Exchange, or other stock exchange, Northera will issue to Cornish Metals common shares in the capital of Northera having an aggregate market value equal to $5 million.

Sleitat : the Company is in discussions to dispose of the Sleitat tin-silver exploration asset located in Alaska, USA.

Publication of sustainability report and Digbee rating

The Company published its inaugural sustainability report for the 2024 reporting year marking a meaningful milestone. The report, published in accordance with the Global Reporting Initiative (" GRI ") Standards, outlines the Company's performance and progress across key sustainability pillars, including governance and ethics, social responsibility and environmental stewardship, establishing a baseline for future reporting.

Cornish Metals was awarded an inaugural overall sustainability rating of "A" by an independent panel of globally recognised sustainability experts from Digbee. This initial submission provides insights to enhance risk mitigation strategies, ensuring well-informed decision-making as the Company advances towards the responsible operation of South Crofty.

Financial highlights for the six months ended June 30, 2025 and June 30, 2024

• Operating expenses have risen reflecting increased professional fees associated with the planned re-domiciliation of the Company from Canada to the UK and costs relating to more corporate activity as the South Crofty tin project is advanced;
• Project related expenditure of $11.3 million for the advancement of South Crofty, primarily relating to NCK shaft re-access & refurbishment, preparation for the refurbishment of the mid-shaft pump station, ongoing project engineering studies and preliminary work for the construction of workshops & stores;
• Dewatering costs of $3.1 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 $63.3 million to $73.8 million at the period end due to the proceeds received from the Fundraise offset by ongoing development activities at the South Crofty tin project.
  

Outlook

As described above, the Company continues to advance and de-risk the South Crofty tin project towards production. The Company's near-term objectives are as follows:

• Complete dewatering of South Crofty mine and refurbishment of NCK shaft;
• Advance detailed engineering and Front End Engineering Design (" FEED ");
• Place deposits for long lead items of plant and equipment;
• Commence and advance early project works, including initial construction of the groundworks for the processing plant; and
• Arrange project financing for the South Crofty tin project.
