The construction of the water treatment plant is nearing completion and we anticipate its commissioning this summer, followed by commencement of dewatering the mine.

Similarly, good progress is being on the metallurgical drill programme with its completion anticipated in early summer. The results of this programme are feeding into the Feasibility Study which is also progressing well. All these workstreams should result in a potential construction decision being taken by the end of 2024.

After completion of the metallurgical drill programme in early summer, we are considering options for the continuation of the exploration programmes at the Wide Formation, located along the southern boundary of South Crofty Underground Permission area and only one kilometre south of the South Crofty's Tuckingmill Decline, and United Downs, located 8km east of South Crofty, to demonstrate the Mineral Resource potential of these targets.

We are continuing to actively engage with and receive strong support from the local community and Cornwall Council."

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 were 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.

Results from exploration program at Carn Brea

Outside of the United Downs project area, a further target, Carn Brea, was also drill tested. Carn Brea is located along the southern boundary of the South Crofty underground permission area. At Carn Brea, eight holes were drilled totaling 2,501 meters. The drill holes confirmed up-dip, near-surface, extensions of the historic Great Flat Lode and discovered tin mineralization in a new target called the 'Wide Formation', inferred to lie parallel to, north of, and beneath the Great Flat Lode. The Great Flat Lode was mined historically over a five kilometer strike length.

Management is of the view that there is merit in further exploring the Wide Formation as this discovery is immediately adjacent to the South Crofty tin project. The Company is considering the next steps for continuing the exploration program on the Wide Formation to better define its geometry (strike and dip).

Construction progress of water treatment plant at South Crofty

The Company has employed key project management personnel, including a Project Manager and Project Engineer, for construction and commissioning of the WTP.

Construction progress of the WTP at South Crofty has included various enabling works, including completion of the treated water discharge duct from the WTP and the concrete foundation pad for the WTP itself. The pipelines carrying water from the submersible pumps in New Cook's Kitchen shaft to the WTP are substantially complete.

The WTP comprises nine reaction tanks for increasing and decreasing the pH to precipitate the various metals in solution, and six inclined plate settling tanks (lamella clarifiers) to remove the precipitated solids. All the tanks and clarifiers have been installed. The structural steel supports and walkways which provide access to the WTP are currently being installed.

The mechanical, electrical and instrumentation equipment is expected to commence installation by the end of April 2023 along with reagent storage, make-up and dosing equipment, which are being supplied as complete packages from specialist manufacturers.

Sand Separation Systems Limited, an industry leader in the treatment of mine water, have supported the running of a pilot plant to optimise the water treatment process flowsheet. This workstream has resulted in a reduction in reagent consumption, an improvement to metal and suspended solids recovery and an expected reduction in operating costs.

Overall, the current cost estimate for the WTP is expected to be between £6.5 million and £7.0 million, with commissioning planned in summer 2023. Preference has been given, where feasible, to suppliers located in Cornwall.

Preparation for mine dewatering at South Crofty

The Company has recruited additional employees to its mining team in anticipation of increased mining related activities during dewatering of the mine and support for underground drilling. All mine staff are receiving enhanced training reflecting the increased level of underground activities. Two mine rescue teams have also been established as part of the mutual aid scheme operating in the south-west of the UK.

New self-contained self-rescuers have been purchased and commissioned, with a new underground refuge chamber also having been constructed and commissioned. New ventilation ducting has been installed in support of the underground drilling for the metallurgical study drill program, as noted below. WiFi connections have been installed underground to provide improved communications with surface.

The two submersible pumps for the mine dewatering purchased in 2018 are being tested ahead of their lowering into the New Cook's Kitchen shaft. Lowering of the pumps into New Cook's Kitchen shaft will commence in May 2023. Pump and pipe handling infrastructure has also been installed around the headframe in readiness for the lowering of the pumps and pipes.

A new single drum winder has been ordered with delivery expected in October 2023. This winder will enable the New Cook's Kitchen's shaft to be re-accessed once dewatering activities are underway.

Metallurgical study drill program underway 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 between 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 No. 4 and No. 8 Lodes (central part of the Mineral Resource), Roskear and Dolcoath South (western part of the Mineral Resource). These five main lodes / mineralized zones contain the majority of the mineralized material anticipated to be processed during the first six years of mine life.

All mineralized sample material required from No. 4 Lode, No. 8 Lode, Roskear and North Pool Zone has been collected and initial metallurgical studies have commenced. All of the metallurgical studies, except for Dolcoath South, are expected to be completed by the end of 2023 for inclusion in the Feasibility Study planned for completion by the end of 2024.

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 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.

Preparation of Feasibility Study

Work on the Feasibility Study has been underway since June 2022. In addition to the metallurgical testwork program noted above, the Feasibility Study continues to advance with the following activities:

• Fairport Engineering has been engaged to design the process plant and estimate capital and operating costs;
• A geotechnical site investigation for the process plant has been completed by AGS Ground Solutions;
• MiningOne has been engaged to conduct numerical modelling and ground control studies for underground mining method and stope designs; and
• Entech Mining has been engaged to provide a study on the refurbishment, re-equipping and operation of New Cook's Kitchen shaft.

It is planned that the Feasibility Study will be completed by the end of 2024.

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.

In addition, on October 19, 2022, agreement was reached with Roskear Minerals LLP ("Roskear Minerals") to lease certain mineral rights located immediately adjacent to the southern boundary of the South Crofty mine. The agreement covers an area of 49 hectares which includes part of the historic Great Flat Lode and lies within the Company's Carn Brea exploration area, as noted above. The agreement is for an initial prospecting lease for five years, with the Company having the option to extend for a further five years if required. The agreement can be converted to a mining lease at any time within the ten year period. The agreement will enable the Company to explore and, if successful, mine within the lease area, subject to receipt of mining permissions for that particular area that lies outside of the current South Crofty underground permission area.

These agreements supplement the agreement reached with Roskear Minerals 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") was 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 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.

Appointment of new director

On June 6, 2022, Mr. Tony Trahar was nominated by VBR to serve as its representative on the Company's board of directors. 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 years ended January 31, 2023 and 2022

• Higher promotional and corporate expenses following successful fundraise cornerstoned by VBR and progression of the South Crofty tin project;
• Unrealized gain of $752,368 arising from increased valuation of holding in Cornish Lithium (carrying value: $2.3 million at January 31, 2023) following its most recent fundraising completed in June 2022;
• Costs of $676,059 and $222,236 capitalized in connection with the exploration programs at United Downs and Carn Brea, respectively (excluding capitalized depreciation and other non-cash items);
• Expenditure of $4.0 million on the construction of the WTP, related dewatering equipment and new or replacement equipment for the mine;
• Other project related costs of $5.6 million incurred since the closing of the Offering relating to the advancement of the South Crofty tin project to a potential construction decision, primarily for the metallurgical drill program and planning activities for the WTP;
• Gross proceeds raised from the Offering of £40.5 million ($65.1 million), following gross proceeds raised from the AIM listing in comparative period of £8.2 million ($14.4 million);
• Interest income of $417,136 arising from increased interest rates being received on higher cash balance following the Offering; and

• Foreign exchange gain of $758,216 arising from appreciation of the British pound compared to the Canadian dollar since closing of the Offering and the resulting translation impact on the cash balance.

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 (December 2024). 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 by the summer 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 by the end of 2024; and
• Commence basic and detailed engineering studies, construction of the processing plant, refurbishment of underground facilities and other on-site early works.
