Cornish Metals Inc. has filed a technical report for its South Crofty Tin Project on SEDAR. The report, titled "South Crofty Tin Project - Mineral Resource Update NI 43-101 Technical Report," was prepared by AMC Consultants (UK) Limited and co-authored by Mr. N. Szebor and Mr. R. Chesher. The report summarizes the updated mineral resource estimate for the South Crofty Tin Project.

The South Crofty Tin Project is a historical, high-grade, underground tin mine in Cornwall, United Kingdom. It has Planning Permission for underground mining, a mine water treatment plant, new processing facilities, and an Environmental Permit to dewater the mine. The project has the 4th highest grade tin Mineral Resource globally and benefits from multiple shafts for future operations.

Tin is considered a Critical Mineral, and responsible sourcing and security of supply are important factors in the energy transition and technology growth. South Crofty has strong support from the local community and regional and national governments. The project has the potential to generate 250-300 direct jobs.

Cornish Metals is a dual-listed company focused on advancing the South Crofty Tin Project and exploring its additional mineral rights in Cornwall, UK. The former producing South Crofty tin mine closed in 1998 after over 400 years of continuous production.

The updated Mineral Resource estimate for the South Crofty Tin Project includes indicated and inferred resources for the Lower Mine and the Upper Mine. The estimate was completed in accordance with the requirements of the Joint Ore Reserves Committee of the Australian Institute of Mining and Metallurgy. The Qualified Person for the estimate is Mr. Nicholas Szebor of AMC Consultants (UK) Limited.

The Mineral Resource estimate includes assumptions for process recovery, metal prices, and metal equivalency calculations. Assays were capped by lode, and bulk densities were applied for ore volume to tonnes conversion. The Mineral Resources are classified as indicated and inferred based on drillhole and channel sample distribution and density, interpreted geological continuity, and data quality. The resources have been depleted for past mining but still contain portions of the mineralization.
