CORNISH METALS CLOSES FINAL TRANCHE OF FUNDRAISING AND APPOINTS MR. JAMES WHITESIDE TO THE BOARD OF DIRECTORS

March 24, 2025

Cornish Metals Inc. (AIM/TSX-V: 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 closed the second and final tranche of the Fundraising previously announced on January 28, 2025 (the "Launch Announcement").  The Company is also pleased to announce that Mr. James Whiteside has joined the Board of Directors as Non-Executive Director, effective immediately. 

Closing of the Fundraising

Proceeds of the Fundraising will be principally used to ensure that the Company can continue with its path to development through completing the shaft refurbishment and de-watering process, the start of early project works, ordering long lead items and completion of the project finance process and up to the point of the formal final investment decision at its South Crofty Tin Mine.

Capitalised terms in this announcement have the same meaning as in the Launch Announcement unless otherwise indicated.

As previously announced, on March 18, 2025 all Resolutions were passed at the Special Meeting which granted the Company the necessary shareholder approvals to carry out the Fundraising, and on March 20, 2025, approval from the TSX Venture Exchange (the "TSX-V") was received to proceed to close the final tranche of the Fundraising.

Accordingly, Admission of, in aggregate, 583,325,689 Second Tranche New Shares occurred at 8.00 a.m. (London time) today (24 March 2025) at which point the Fundraising completed. The Second Tranche New Shares comprised: 17,705,101 Second Tranche Placing Shares; 356,911,283 NWF Subscription Shares; 191,320,934 Second Tranche VBR Subscription Shares; 245,004 Second Tranche Director Subscription Shares; and 17,143,367 Retail Offer Shares, raising gross proceeds of £46,666,055 (approximately C$83,406,240).

The Second Tranche New Shares are fully paid and rank pari passu in all respects with the existing Common Shares, including the right to receive all dividends and other distributions declared, made or paid after the date of issue.

Following Admission, the total number of Common Shares of the Company in issue is 1,252,414,079. The total number of voting rights in the Company is therefore 1,252,414,079 ("Total Voting Rights"). The Total Voting Rights may be used by shareholders as the denominator for the calculations by which they will determine if they are required to notify their interest in, or a change to their interest in the Company under the FCA's Disclosure, Guidance and Transparency Rules. The Company does not hold any shares in treasury.

On Admission, Vision Blue Resources Limited now holds 29.14% of the Total Voting Rights and the National Wealth Fund Limited holds 28.50% of the Total Voting Rights.

For further details of the Fundraising, please refer to: (i) the Launch Announcement; (ii) the news release dated January 28, 2025 (Titled: "Result of Fundraising"); (iii) the news release dated January 31, 2025 (Titled: "Results of Retail Offer"); (iv) the news release dated February 7, 2025 (Titled: "Cornish Metals Closes First Tranche of Fundraising"); and (v) the news release dated March 18, 2025 (Titled: "Cornish Metals Announces Results of Special Meeting of Shareholders"), copies of which are available on the Company's profile on SEDAR+ at www.sedarplus.ca.

Participation by the Participating Directors constitutes a "related party transaction" within the meaning of Policy 5.9 of the rules and policies of the TSX-V and Multilateral Instrument 61-101 - Protection of Minority Security Holders in Special Transactions ("MI 61-101"). Vision Blue Resources is also deemed to be a "related party" of the Company pursuant to MI 61-101 given that it holds more than 10% of the Company's issued share capital. The "related party transaction" requirements under Policy 5.9 of the TSX-V and MI 61-101 do not apply to the Participation Right, since the subscription by Vision Blue of the VBR Participation Right Shares satisfies the exclusion from such requirements under Section 5.1(h)(iii) of MI 61-101. In connection with the Director Participations, the Company is relying on: (i) the exemption from the formal valuation requirement in section 5.5(b) of MI 61-101 as a result of the Common Shares only being listed on the TSX-V and being admitted for trading on AIM; and (ii) the exemption from the minority approval requirement in section 5.7(1)(a) of MI 61-101 as neither the fair market value of the Common Shares to be distributed to, nor the fair market value of the consideration to be received from, insofar as it involves interested parties (being, Vision Blue in respect of the Additional VBR Subscription and the Director Participations), exceeds 25% of the Company's market capitalization.

In accordance with applicable Canadian securities legislation, the Second Tranche Placing Shares, the NWF Subscription Shares; the Second Tranche VBR Subscription Shares, the Second Tranche Director Subscription Shares and the Retail Offer Shares will be subject to a hold period of four months which expires on July 25, 2025, such hold period will only apply to trades (as defined under applicable Canadian securities legislation) of such shares in Canada or through a market in Canada, such as the TSX-V.

In connection with closing of the second tranche of the Fundraising, total commission payable to the Placing Agents in respect of the Second Tranche Placing Shares is £195,820 (approximately C$349,990).  All C$ equivalents of the amounts referred to in this announcement have been calculated using the Bank of Canada's closing exchange rate for January 24, 2025 of C$1.7873/£1.
