Vancouver, October 1, 2023

Cornish Metals Inc. (TSX-V/AIM: CUSN) ("Cornish Metals" or the "Company"), a mineral exploration and development company focused on its South Crofty tin project in Cornwall, United Kingdom, announces that it is changing its financial year end from 31 January to 31 December and that it has granted 800,000 incentive stock options over common shares without par value in the Company (the "options") to Executive Management.

Change of Year-End

The Company has decided to change its financial year end to 31 December to better align the Company's financial reporting periods to that of its peer group in the mineral resources sector. In addition, the calendar year end coincides with traditional financial, taxation and operational cycles.

As a result of the change of the financial year end, key dates in the Company's future reporting calendar will be as follows:

·    Publication of unaudited accounts for the nine month period ending 31 October 2023 no later than 1 January 2024;

·    Publication of audited accounts for the eleven month period ending 31 December 2023 no later than 29 April 2024;

·    Publication of unaudited accounts for the three month period ending 31 March 2024 no later than 30 May 2024; and

·    Publication of unaudited accounts for the six month period ending 30 June 2024 no later than 29 August 2024.
