Preliminary Economic Assessment completed for South Crofty Project

The results of the South Crofty Project PEA were released on April 30, 2024, validating the Project's economic viability and potential to be a low-cost and long-life tin mining operation with a current 14-year LOM. South Crofty is expected to produce a clean, high-grade tin concentrate and to be an important tin producer in Europe, supplying into the growing demand for this critical metal that is essential for the energy transition.

Key highlights from the PEA include:

• After-tax NPV8% of US$201 million and 29.8% after-tax IRR at base case tin price of US$31,000/tonne;
• Pre-production capital requirement of US$177 million;
• Capital pay-back period of three years after-tax;
• Total after-tax cash flow of US$626 million from start of production, peaking at US$82 million in second year of production;
• Average annual earnings before interest, taxes, depreciation and amortization ("EBITDA") of US$83 million and 62.1% EBITDA margin in years two through six;
• 49,310 tonnes of tin metal in concentrate produced over a 14-year LOM
• Average annual tin production of over 4,700 tonnes for years two through six, equivalent to approximately 1.6% of global mined tin production;
• LOM average all-in sustaining cash cost ("AISC") of US$13,661/tonne of payable tin, positioning South Crofty as a low cost tin producer;
• Growth opportunities from additional in-mine and near-mine exploration with the potential to materially extend the mine life and increase production; and
• Potential to directly employ up to 320 people with permanent high-skilled and well-paid jobs and create up to 1,000 indirect jobs.

Further details can be found in the news release dated April 30, 2024 and the Technical Report entitled "South Crofty PEA" prepared in accordance with NI 43-101 and filed on SEDAR+.

Refurbishment of New Cook's Kitchen Shaft - second phase commenced

Phase 2 of NCK shaft refurbishment is underway, following the on-schedule installation of a new double-deck equipping stage and modified main cage, providing a safe and stable work platform enabling faster replacement of the old shaft timbers with new steel buntons and guides (refer news release dated July 10, 2024). Rephasing shaft refurbishment, concurrent with mine dewatering, will improve the functionality of NCK shaft, enable larger equipment to access the mine at an earlier stage in its re-development and ensure that high health and safety standards are applied as the underground mine workings are accessed.

The NCK shaft winding engines and associated winding apparatus, including the refurbished south headframe, have been fully commissioned and, following successful third-party compliance testing, have been certified for use. This system enables safe access to NCK shaft for personnel and materials as required to facilitate the shaft refurbishment works and subsequent access to the dewatered deep workings of the mine. Mine dewatering continues with the submersible pumps and water treatment plant operating to specifications. The water level in NCK shaft is being maintained at approximately 280 metres below surface and the treated water being discharged to the Red River is consistently well within the permitted standards.

Shaft refurbishment and mine dewatering is anticipated to reach the 195-fathom level (approximately 350 metres below surface) in Q4-2024 and refurbishment of the 195-fathom pump station and installation of permanent pumps is scheduled to be completed in Q1-2025. Shaft refurbishment and mine dewatering are expected to be complete by September 2025.

Land purchase adjacent to South Crofty surface infrastructure

On May 21, 2024, the Company announced the purchase of a 7.7 acre land package situated to the south of Kerrier Way, immediately adjacent to important South Crofty surface infrastructure. The land purchase removes reliance on existing right-of-passage agreements, providing the Company with direct access to all surface infrastructure, as well as additional space for future site works, opportunities for potential operating cost savings, renewable energy initiatives and improved overall property security.

Exploration drill program at Carn Brea South

A 9,000-meter exploration drill program was completed at the Wide Formation target in the Carn Brea South exploration area in June 2024. The drill program was designed to test the geometry and the continuity of tin mineralization discovered by the Company at the Wide Formation target (refer news release dated January 10, 2023).

The mineralization style in the Wide Formation, comprising pervasive tourmaline and quartz (termed 'blue peach'), is similar in character to that associated with No. 8 Lode, one of the most prolific tin producing lodes in the latter years of operation of the South Crofty mine. The drill program tested an area measuring 2,500 meters along strike (northeast to southwest) and 800 meters downdip (north to south).

Drill results from the first six holes (refer news release dated February 4, 2024) confirm the Wide Formation structure over a 1.6km strike length, a downdip extent of at least 525 meters and thicknesses ranging from 1.8 meters - 4.8 meters. The structure remains open. Notable tin intercepts from the Wide Formation include 1.21 meters grading 0.87% Sn in CB23_004.

Drilling also identified a new mineralized structure lying directly beneath the Great Flat Lode (named the "Great Flat Lode Splay"), and several high-grade, steeply dipping tin zones between the Great Flat Lode and the Wide Formation. Notable tin intercepts from the newly identified Great Flat Lode Splay include 3.38 meters grading 1.01% Sn in CB23_002.

Notable tin intercepts from multiple steeply-dipping, high-grade tin zones mainly intersected between the Great Flat Lode and the Wide Formation include 3.09 meters grading 1.21% Sn in CB23_001.

All samples have been submitted for analysis and final assay results will be reported when available.

Sale of Mactung and Cantung royalties

The Company completed the sale of its royalty interests on the Mactung and Cantung tungsten projects located in Northern Canada to Elemental Altus for a total cash consideration of US$4.5 million (refer news release dated July 21, 2024). The initial cash consideration of US$3.0 million was received by the Company on August 1, 2024 (refer news release dated August 4, 2024), with the balance of US$1.5 million due by August 1, 2025.

Sale of Nickel King Property

On June 16, 2024, the Company entered into a binding letter of intent with Northera for the sale of the Company's 100% interest in the Nickel King Property for a total consideration of up to C$8 million (refer news release dated June 16, 2024). Under the terms of the agreement, Northera made a non-refundable cash payment of C$100,000 on June 14, 2024. Within 95 days of signing the agreement, the Company will transfer the Nickel King Property upon receipt of a further non-refundable cash payment of C$900,000. Upon completion of a go-public transaction by Northera, resulting in a listing of securities on the TSX Venture Exchange, or other stock exchange, Northera will issue to the Company common shares in the capital of Northera having an aggregate market value equal to C$7.0 million.

Appointment of Samantha Hoe-Richardson as independent non-executive director

On January 8, 2024, the Company announced that Samantha Hoe-Richardson joined the Board of Directors as an independent non-executive director (refer news release dated January 8, 2024). Ms. Hoe-Richardson is an experienced non-executive director from a global mining, infrastructure and insurance background. She is currently a non-executive director of WE Soda Ltd, Assured Guaranty UK Ltd, Ascot Underwriting Limited and an independent advisor on climate change & sustainability to Laing O'Rourke. Ms. Hoe-Richardson was Head of Environment & Sustainable Development at Network Rail until 2017 and prior to that spent 16 years at Anglo American Plc, latterly as Head of Environment. She previously worked in investment banking and audit. Ms. Hoe-Richardson holds a Masters Degree in nuclear and electrical engineering from the University of Cambridge, and is also a non-practicing Chartered Accountant.

ABOUT CORNISH METALS

Cornish Metals is a dual-listed mineral exploration and development company (AIM and TSX-V: CUSN) focused on advancing the South Crofty high-grade, underground tin project through to a construction decision, as well as exploring its additional mineral rights, located in Cornwall, United Kingdom.

• South Crofty is a historical, high-grade, underground tin mine that started production in 1592 and continued operating until 1998 following over 400 years of continuous production;
• The Project possesses Planning Permission for underground mining (valid to 2071), to construct new processing facilities and all necessary site infrastructure, and an Environmental Permit to dewater the mine;
• South Crofty is one of the highest grade tin Mineral Resources globally and benefits from existing mine infrastructure including multiple shafts that can be used for future operations;
• The 2024 Preliminary Economic Assessment for South Crofty validates the Project's potential (see news release dated April 30, 2024 and the Technical Report entitled "South Crofty PEA"):
  • US$201 million after-tax NPV_8% and 29.8% IRR
  • 3-year after-tax payback
  • 4,700 tonnes average annual tin production in years two through six
  • Life of mine all-in sustaining cost of US$13,660 /tonne of payable tin
  • Total after-tax cash flow of US$626 million from start of production
• Tin is a Critical Mineral as defined by the UK, American, and Canadian governments;
• Tin connects almost all electronic and electrical infrastructure, making it critical to the energy transition - responsible sourcing of critical minerals and security of supply are key factors in the energy transition and technology growth;
• Approximately two-thirds of the tin mined today comes from China, Myanmar and Indonesia;
• There is no primary tin production in Europe or North America;
• South Crofty benefits from strong local community, regional and national government support.
• Cornish Metals has a growing team of skilled people, local to Cornwall, and the Project could generate up to 320 direct jobs.
  

The 2024 Preliminary Economic Assessment for South Crofty is preliminary in nature and includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorised as mineral reserves. There is no certainty that the 2024 Preliminary Economic Assessment will be realised. Mineral resources that are not mineral reserves do not have economic viability.
