• Issuance of a second tranche of common shares pursuant to the restructuring of the deferred consideration relating to the acquisition of the South Crofty tin project and associated mineral rights in Cornwall (news release dated May 29, 2022);
• Commencement of a drill program in July 2022 to collect samples for metallurgical testwork as part of the Feasibility Study, with the program likely to be between 8,000 and 12,000 meters of drilling (news release dated July 10, 2022);
• Key positions were filled to the South Crofty project management team, including Project Manager for the construction and commissioning of the water treatment plant, Feasibility Study Manager and Project Engineer;
• All substantial component parts of the water treatment plant ordered with construction expected to commence before the end of October 2022; and
• Mr. Tony Trahar nominated by Vision Blue Resources as its representative on the Board (news release dated June 5, 2022).

Richard Williams, CEO of Cornish Metals, stated, "Since the completion of the £40.5m financing at the end of May, orders have been placed for almost all component parts of the water treatment plant. Notwithstanding supply constraints, we remain confident that commissioning of the water treatment plant remains on track for the first half of 2023, with dewatering activities commencing thereafter.

"After completion of the first phase of the successful exploration program at United Downs, we have now commenced a drill program for the metallurgical testwork which is an integral part of the South Crofty Feasibility Study. We have also had a successful period recruiting key members of the project team (Project Manager, Project Engineer and Feasibility Study Manager).

"Work has continued at pace in recent months and I look forward to reporting on progress at South Crofty in due course."

Review of activities

Results from exploration program at United Downs

The Company commenced its exploration program at United Downs in April 2021. The drilling activities were contracted to Priority Drilling Limited, under the supervision of the Company's geological team.

Four targets were drill-tested: UD Lode, United Mines, Mount Wellington and Trenares Lode. The key points to date arising from this drill program are:

• Multiple zones of copper - tin - silver - zinc mineralization have been intersected;
• High-grade copper - tin mineralization was intersected down dip beneath the historic United Mines; and
• A transition from high-grade copper to high-grade tin at depth as well as increasing tin grades with depth has been encountered, similar to the mineralization transition seen at South Crofty.
  

Details of the intercepts from the drill program can be found in the press releases dated July 5, 2021, August 30, 2021, November 3, 2021, December 6, 2021, June 29, 2022 and August 23, 2022. In total, 26 holes were drilled at United Downs amounting to 10,159 meters, of which all assay results have been reported in these press releases. Drilling ceased at the end of May 2022, with the metallurgical study drill program at South Crofty commencing soon thereafter, as described below.

In summary, results from the United Downs exploration program confirm management's belief in the potential to develop a Mineral Resource in the United Downs project area, especially the down dip section of the United Mine where high-grade copper, tin and silver grades were encountered. The Company is considering the next steps for advancing the United Downs project.

Outside of the United Downs project area, a third target, Carn Brea has also been drill tested. Carn Brea is located approximately two kilometers southeast of the South Crofty tin project. At Carn Brea, eight holes have been drilled totaling 2,501 meters. Drilling has now ceased and assays will follow when available.

Agreement of South Crofty mineral leases

On February 4, 2022, agreement was reached with Sir Ferrers Vyvyan of Trelowarren in Cornwall to lease certain mineral rights owned by the Vyvyan family. The mineral lease covers an area of 222 hectares and is valid for 25 years. The lease will enable the Company to explore and mine within all the mineral right areas owned by the Vyvyan family inside the South Crofty mine, and to explore certain other mineral right areas adjacent to the South Crofty mine.

The agreement with the Vyvyan family supplements the agreement reached with Roskear Minerals LLP in March 2021 (the "Roskear Agreement") to lease their mineral rights within the South Crofty tin project. The Roskear Agreement enables the Company to explore and develop the mineral resources that are contained in the Roskear section of the South Crofty mine.

Strategic investment by Vision Blue Resources

On May 24, 2022, a financing of £40.5 million ($65.1 million based on the closing exchange rate as at May 24, 2022) (the "Offering") completed, which included a £25.0 million (approximately $40.1 million based on the closing exchange rate as at May 24, 2022) strategic investment by Vision Blue Resources Limited ("VBR"). The balance of the Offering was completed through a private placement with certain Canadian and UK investors and eligible private investors.

A summary of the Offering is described below. Further details can be found in the press releases dated March 27, 2022 and May 23, 2022.

The Offering was structured through a unit offering comprising one common share at £0.18 ($0.30 for Canadian investors) and a warrant to purchase one common share priced at £0.27 ($0.45 for Canadian investors) for a period of 36 months from the closing date of the Offering. A total of 225,000,000 units have been issued, comprising around 44.0% of the issued share capital as at May 24, 2022, excluding the effect of the issuance of the Milestone Shares as described below. VBR held approximately 27.2% of the enlarged issued share capital upon closing of the Offering.

The planned use of the proceeds from the Offering is to complete the dewatering program and Feasibility Study at South Crofty, evaluate downstream beneficiation opportunities and commence potential on-site early works in advance of a potential construction decision. The proceeds raised under the Offering are budgeted to fund a 30 month program from closing of the Offering.

Pursuant to an Investment Agreement entered into between the Company and VBR, upon closing of the Offering, VBR retains the following rights, among others, subject to certain terms and conditions:

• For so long as its shareholding in the Company is in aggregate not less than 10% of the Company's issued share capital:
  • Nomination of one person to the Company's board of directors as a non-executive director as an additional director to the current board of directors (the "Investor Director"), with Mr. Trahar being appointed to this position on June 6, 2022, as described below;
  • Nomination of one person to the Company's technical committee to be formed from closing of the Offering, which person may be a person other than the Investor Director; and
  • A participation right to maintain its percentage ownership interest in the Company upon any offering of securities at the subscription price and similar terms as are applicable to such offering; and
• For so long as its shareholding and its affiliates' shareholdings in the Company are in aggregate not less than 5% of the Company's issued share capital, the appointment of an observer to the board of directors of the Company.
  

On closing of the Offering, VBR entered into a Relationship Agreement with the Company and SP Angel Corporate Finance LLP (the Company's nominated adviser on AIM), relating to the carrying on of the Company's business in an independent manner following the closing of the Offering.

The Company has undertaken to VBR to use its reasonable commercial efforts to complete a Feasibility Study in respect of South Crofty on or before 31 December 2024.

The Offering was subject to the approval of the TSX-V and shareholders, both of which were received by May 19. 2022.

Issuance of shares as deferred consideration payable for the Cornwall mineral properties

On June 30, 2021, agreement was reached with Galena Special Situations Limited (formerly Galena Special Situations Master Fund Limited) and Tin Shield Production Inc. (together the "Sellers") to restructure the outstanding deferred consideration payable to the Sellers on the acquisition of the South Crofty tin project and associated mineral rights (the "Side Letter"). The fixed and variable payments that existed under the original share purchase agreement were replaced with fixed payments linked to pre-agreed project related milestones.

Pursuant to the Side Letter, 20,298,333 common shares were issued to the Sellers on May 31, 2022 ("Milestone Shares"). This payment was triggered by the Company raising funding for the dewatering of the South Crofty mine within the planned use of proceeds from the Offering, as described above.

The Milestone Shares represent consideration equivalent to an amount of US$4,750,000 ($6,089,500 at a US dollar / Canadian dollar exchange rate of 1.2820) at a deemed price of $0.30 per common share. The deemed price was the same price under which Canadian investors subscribed to the Offering pursuant to the terms of the Side Letter. The value of the Milestone Shares in accordance with IFRS is $9,844,692, being the market price of the Milestone Shares at their date of issuance.

As a result of this payment, the remaining deferred consideration payable to the Sellers is US$5,000,000 in common shares, payable upon a decision to proceed with the development and/or construction of a mine either at the South Crofty tin project or at the United Downs property.

Disposal of Sleitat royalty to Electric Royalties

On May 27, 2022, the disposal of a 1% Net Smelter Royalty on the Sleitat tin-silver project located in Alaska, USA to Electric Royalties Ltd. was completed. The consideration was $100,000 and 1,000,000 common shares in Electric Royalties, which in aggregate amounted to $355,000 at the date of completion.

Construction progress of water treatment plant at South Crofty

Construction progress of the WTP at South Crofty has included various enabling works and the placing of orders for a number of long lead items, all of which have been delivered to site. The preparation work for the laying of the concrete foundation slab for the WTP has also been completed.

Detailed design work for the WTP is continuing with Galliford Try Construction Limited ("GT"). The procurement process is also underway, with GT specifying the major mechanical equipment and identifying suitable sub-contractors for construction activities.

Sand Separation Systems, an industry leader in the treatment of mine water, have supported the running of a pilot plant to optimise the water treatment process flowsheet.

Commencement of metallurgical study drill program at South Crofty

A drill program as part of the South Crofty Feasibility Study was started in July 2022. The drill program is anticipated to require approximately 8,000 and 12,000 meters of drilling.

Three drill rigs have been contracted from Priority Drilling Limited, under the supervision of the Company's geological team. Two rigs are drilling from surface and one rig is drilling from underground, collecting samples from the North Pool Zone (eastern section of Mineral Resource), the #4 and #8 Lodes (central part of the Mineral Resource), and Roskear / Dolcoath South (western part of the Mineral Resource).

The program is designed to collect samples for various metallurgical studies, including XRT ore sorting, flowsheet optimisation and paste backfill studies, as well as collecting assay data to complement the current Mineral Resource Estimate. This testwork should allow the acceleration of the Feasibility Study in advance of dewatering the mine and will provide key information for the mineral processing flowsheet, especially the amenability of the mineralized zones to ore sorting which, if successful, will present an opportunity to deliver higher grade feed and reduce the size of the processing plant.

Appointment of new director

On June 6, 2022, Mr. Tony Trahar was nominated by VBR to serve as its representative on the Board. Mr. Trahar is currently a special adviser to VBR.

Mr. Trahar has had a 40 year career in the mining, natural resources and industrial sectors. From 2000 to 2007 he was Chief Executive of Anglo American Plc, one of the world's largest mining groups, and was also a director of Anglo Gold, Anglo Platinum and De Beers.

From 1985 to 2000, Mr. Trahar was Chief Executive, and then Chairman of Mondi Ltd (now listed in London as Mondi Plc), a multinational forestry, pulp, paper and packaging group. Since leaving Anglo American, Mr. Trahar has also held a number of senior advisory roles for Barclays Natural Resource Investments (2007 to 2013) and Macquarie Bank (2014 to 2016).

Financial highlights for the six months ended July 31, 2022

• Higher promotional and corporate expenses relating to increased media/investor activities following last year's AIM listing, preparatory work for the successful fundraise cornerstoned by Vision Blue Resources and progression of the South Crofty tin project;
• Unrealized gain of $542,204 arising from increased valuation of holding in Cornish Lithium following its most recent fundraising completed in June 2022;
• Costs of $687,603 and $226,884 capitalized in connection with the exploration program at United Downs and Carn Brea, respectively (excluding capitalized depreciation and other non-cash items);
• Project related costs of $732,538 incurred since the closing of the Offering relating to the advancement of the South Crofty tin project, primarily for the metallurgical drill program, planning activities and new or replacement equipment;

• Recognition of foreign currency translation loss of $2,098,402 for those assets located in the UK when translated into Canadian dollars for presentational purposes.

Outlook

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. The planned use of the proceeds from the Offering is to complete the dewatering program and Feasibility Study at South Crofty, evaluate downstream beneficiation opportunities and commence potential on-site early works in advance of a potential construction decision.

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

• Construct and commission the WTP in the first half of 2023 and thereafter complete the dewatering of the mine within 18 months;
• Complete drill programs for metallurgical studies and to produce an updated JORC compliant Mineral Resource estimate for a Feasibility Study;
• Complete a Feasibility Study using all reasonable commercial efforts on or before 31 December 2024; and
• Commence basic and detailed engineering studies, construction of the processing plant, refurbishment of underground facilities and other on-site early works.
