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, 2024 and for the period ending May 22, 2024

(All figures expressed in Canadian dollars unless otherwise stated)

·   South Crofty Preliminary Economic Assessment ("PEA") completed, validating the South Crofty tin project's economic viability (news release dated April 30, 2024):

o  After-tax Net Present Value ("NPV") of US$201 million and Internal Rate of Return ("IRR") of 29.8%;

o  Average annual tin production of over 4,700 tonnes for years two through six, totaling 49,310 tonnes over a 14-year Life of Mine;

o  Total after-tax cash flow of approximately US$626 million from start of production.

·    Purchase of land totaling 7.7 acres located immediately adjacent to South Crofty surface infrastructure (news release dated May 21, 2024):

o  The purchased land removes reliance on existing right-of-passage agreements, providing the Company with direct access to all surface infrastructure as well as additional space for future site works, opportunities for potential operating cost savings, renewable energy initiatives and improved overall property security.

·    Refurbishment of NCK shaft has commenced:

o  Rephasing shaft refurbishment will improve the functionality of New Cook's Kitchen ("NCK")  shaft and enable larger equipment to access the mine at an earlier stage in its re-development (news release dated March 3, 2024);

o  Winders and cages are now installed, fully commissioned and certified to allow for safe transport of equipment and workers within NCK shaft.

·   Mine dewatering continues with the submersible pumps and Water Treatment Plant ("WTP") operating to specifications:

o  Water level in NCK shaft is being maintained at approximately 280 meters below surface with the rate of dewatering being reduced to allow shaft refurbishment and dewatering to proceed concurrently;

o  Treated water being discharged to the Red River continues to exceed the standards permitted by the Environment Agency.

·    The Company announced the appointment of Ken Armstrong, a non-executive director, as Interim Chief Executive Officer ("CEO") effective March 31, 2024, replacing Richard Williams, who also stepped down from the Company's Board:

o  Patrick Anderson, Chairman of the Board, became the Executive Chairman of the Company for the transition period until a permanent CEO is appointed (news release dated March 15, 2024);

o  The process for the appointment of a permanent CEO has commenced with the assistance of an appointed executive search consultant.

·    Samantha Hoe-Richardson joined the Board as independent non-executive director effective January 8, 2024 (news release dated January 8, 2024).

Ken Armstrong, Interim CEO and Director of Cornish Metals, stated, "The Cornish Metals team has recently accomplished an important milestone for the Company, completing a Preliminary Economic Assessment of the South Crofty project that confirms the Project's potential to be a low-cost and long-life tin mining operation. The PEA results are compelling with a post-tax NPV_8% of US$201 million and IRR of about 30%, representing a strong foundation for further evaluation of the Project and enabling the Company to move forward with additional preparation work and progress towards a construction decision."

Financial highlights for the three months ended March 31, 2024 and April 30, 2023

·   Increase in operating expenses impacted by higher travel and marketing expenditure arising from increased investor engagement and termination settlement payable to the former CEO;

·    Expenditure of $1.0 million on new or replacement equipment for the mine, including the final payments for the permanent pumps for the underground pump station, cages and the new winders;

·    Dewatering costs of $1.3 million for power, reagents, sludge disposal and maintenance of the WTP;

·   Other project related expenditure of $2.5 million relating to the advancement of South Crofty to a potential construction decision, primarily for the ongoing feasibility study and NCK shaft re-access;

·    Costs of $0.8 million incurred for the continuation of the exploration program at Carn Brea; and

·    Cash decreased by $9.1 million to $17.0 million at the period end mainly due to ongoing development activities at the South Crofty tin project.

The Company changed its financial year end from January 31 to December 31 with effect from December 31, 2023 with the result that the current period of reporting is the three months ended March 31, 2024.  The comparative period of reporting is the three months ended April 30, 2023.

The Company has allocated funding for near term opportunities to progress the project, the most significant being the purchase of the land located immediately adjacent to South Crofty surface infrastructure. As a consequence of pursuing these opportunities, additional financing will be required before the end of 2024.

Outlook

The Company is advancing the South Crofty tin project to a potential construction decision. The Company's objectives are as follows:

·    Dewater South Crofty mine and refurbish NCK shaft by September 2025;

·    Advancing all stages of the Feasibility Study;

·    Complete the 14-hole / 9,000 metre Wide Formation exploration drill programme, and

·  Commence basic and detailed engineering studies, construction of the processing plant, refurbishment of underground facilities and other on-site early works.

The follow-up exploration drill programme at the Wide Formation target will also continue subject to the receipt of satisfactory drill results.
