Cornish Metals Releases Financial Statements and Management’s Discussion and Analysis for the Three Months Ending 30 April 2021

VANCOUVER, June 24, 2021 - Cornish Metals Inc. (TSX-V/AIM: CUSN) ("Cornish Metals" or the "Company"), a mineral exploration and development company focused on its projects in Cornwall, United Kingdom, is pleased to announce that it has released its interim financial statements and management, discussion and analysis ("MD&A") for the three months ended 30 April 2021. The reports are available under the Company's profile on SEDAR (www.sedar.com) and on the Company's website (www.cornishmetals.com).

Highlights for the three months ended April 30, 2021 and for the period ending June 23, 2021

• Completion of listing and concurrent financing on AIM in February 2021 raising gross proceeds of ?8.2 million ($14.4 million based on closest available exchange rate) to advance the United Downs exploration project and for general working capital purposes;
• Conversion of Osisko loan note in February 2021 into two royalty agreements over mineral properties in Cornwall with an accompanying simplified and reduced security package;
• Agreements reached for the leasing of additional mineral rights at the South Crofty tin project and surface land surrounding the New Roskear Shaft, and binding heads of terms agreed for the disposal of waste material derived from the dewatering of the South Crofty mine;
• Commencement of phased exploration program at the United Downs exploration project in April 2021 to initially delineate further the known mineralized structures and conduct in-fill drilling;
• Increases in Indicated Resource and Inferred Resource by 10.2% and 129.8%, respectively, for the Lower Mine in updated Mineral Resource Estimate for South Crofty mine published in June 2021 (see news release dated June 9, 2021); and
• Financing options continue to be considered to progress the South Crofty tin project.

Richard Williams, CEO of Cornish Metals, stated, "I am delighted with what the Company has achieved in the last few months - a highly successful listing on AIM which surpassed our expectations, the conversion of the Osisko loan note into two royalties which endorsed the quality of the Company's projects in Cornwall, a substantial increase in mineral resource for South Crofty and the commencement of the exploration programme at United Downs. I look forward to reporting imminently on the initial results of that exploration programme once the assays from the first few drill holes have been assessed.

"Longer term, we are continuing to assess various financing options to progress South Crofty which remains a key strategic asset for the Company. South Crofty could potentially play a pivotal role in securing a domestic and sustainable source of battery metals as the UK transitions to a low carbon economy."

Key financial metrics for the first quarter

Outlook

The proceeds from the recently completed AIM listing are to be used to conduct a drill program at the United Downs exploration project, to conduct initial field work on other high priority exploration targets within transport distance of South Crofty, and for general working capital purposes. Management believes that, subject to drilling success, the proceeds from the AIM listing will result in the Company being fully funded to the completion of a maiden JORC resource at the United Downs exploration project.

Within 12 to 18 months of the date of the AIM listing, the Company plans to:

• Commence an 18 month 9,100 meter initial drilling program at United Downs to advance the project to Inferred Mineral Resource definition, fully funded from the proceeds arising from the AIM listing;
• Test three lodes with a 1,000 meter of strike length to a depth of 500 meter in the initial phase. Management believes there are up to seven further mineralized lode structures with a total resource potential of between four million tons and ten million tons;
• Subject to the outcome of the initial drilling program, undertake a subsequent in-fill drilling program at United Downs to advance the project to a feasibility study within three years; and
• Evaluate other near-surface, high potential, exploration targets within transport distance of the planned processing plant site.

In the longer term, the Company intends to develop the South Crofty tin project as and when economic conditions and cashflows are supportive.
