·     Metallurgical testwork results confirm the potential to upgrade the mineralization of the South Crofty mine and enable process design optimization work on the size of the mineral processing plant (news release dated October 8, 2023);

·    Commencement of follow-up exploration drill program at the Wide Formation target in the Carn Brea exploration area (news release dated September 19, 2023).

Richard Williams, CEO of Cornish Metals, stated, "Looking back on 2023, I want to commend the Cornish Metals team for the outstanding progress that has been achieved at South Crofty with some very important milestones being met, in particular, the commissioning of the water treatment plant and the subsequent commencement of mine dewatering that is tracking ahead of expectations.  This progress would not have been achieved without the support of suppliers, the community and other local stakeholders.

Looking ahead to 2024, we can look forward to another busy year.  The continuation of dewatering at deeper levels will allow access to the mine for the first time in over 25 years.  We remain focussed on our objective to complete the dewatering of South Crofty within 18 months from commencement.

The expected completion of the Feasibility Study will move South Crofty a stage further towards a construction decision.  I also look forward to reporting on the results of the drill program at the Wide Formation which, if successful, will benefit the economics of South Crofty with the potential to increase production and extend the mine life.

The financial position of the Company remains healthy and we appreciate the continuing support and advice from our major shareholder, Vision Blue Resources."

Financial highlights for the nine months ended October 31, 2023 and October 31, 2022

·    Increase in operating costs impacted by higher insurance costs attributable to more site-based activities primarily relating to the construction of the WTP and related dewatering work;

·    Interest income of $1.5 million arising from increased interest rates being received on higher cash balance following the Offering;

·    Expenditure of $12.4 million incurred during the period on the construction of the WTP and related dewatering equipment, as well as new or replacement equipment for the mine;

·    Other project related costs of $8.4 million incurred during the period relating to the advancement of South Crofty to a potential construction decision, primarily for the metallurgical drill program and planning activities for dewatering and shaft re-access;

·    Costs of $0.8 million incurred for the continuation of the exploration program at Carn Brea which re-commenced in June 2023; and

·    Recognition of foreign currency translation gain of $1.6 million for those assets located in the UK when translated into Canadian dollars for presentational purposes.

Outlook

As described above, the proceeds raised from the Offering completed in May 2022 are being used to advance the South Crofty tin project to a potential construction decision within 30 months from closing of the Offering. 

Within 30 months from the closing of the Offering, the Company's objectives are as follows:

·    Commence dewatering of the mine and thereafter complete the dewatering of the mine within 18 months;

·    Complete a Feasibility Study using all reasonable commercial efforts; 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 program at the Wide Formation target at Carn Brea South will also continue subject to the receipt of satisfactory drill results.

Subject to the availability of financing, consideration will also be given to continuing with the Company's exploration program at United Downs and evaluating other high potential, exploration targets within transport distance of the planned processing plant site at South Crofty.
