Chairman’s Statement

Dear Shareholder,

I have great pleasure in presenting the Company’s Half-Yearly Report and condensed Financial Statements for the period ended 30 November 2025.   The Company has been carefully progressing the potential of its assets during the period.

Northern Ireland – exploring Nickel, Copper, Platinum Group Elements

The Company holds a significant licence package covering over 1000 km2 in Northern Ireland where it has established first mover advantage and continues to advance its exploration programme exploring for Nickel, Copper and Platinum Group Elements.   Significant work was carried out by Dr Larry Hulbert, a geological consultant, first engaged in early 2024, who carried out an investigation of the licence areas and built a comprehensive database on them incorporating geology, geochemistry, geophysics, remote sensing, and base Geographic Information System (GIS) information including TELLUS data and gravity geophysical data.   

Dr Hulbert’s report confirmed significant potential for Nickel, Copper and Platinum Group Elements and recommended a follow up work programme.   The Company has been progressing with follow on work over the last six months including entering into an enterprise partnership with Trinity College Dublin on a work programme jointly funded by Research Ireland to be carried out on the Platinum Group Element potential of the Company’s licence areas in Ireland over the coming years.   In June 2025 the Company announced that it had identified the site of the historic Cappagh Copper Mine as a significant new target for investigation within the relevant licence area (KDR4).    This provides the Company with a tangible copper target in addition to the targets identified by Dr Hulbert’s report and we look forward to commencing a comprehensive exploration programme to unlock the full potential of this area.

Diamond exploration in Finland

While the market sentiment remains challenging from a diamond investment perspective, the Company is focussing its efforts on carefully progressing exploration work, positioning the Company well for a recovery in the retail sentiment towards natural stones.  The Company’s view is that in a global market segment for natural diamonds that is worth over US$29 billion annually, sustainably produced, traceable European diamonds will command a premium.  This premium would be supported by the potential for the Company’s assets to produce coloured diamonds.  

Exploration work in the Kuhmo region

Exploration work has continued in the Kuhmo region in Finland with the Company focussing in particular on the geophysical Anomaly 5 as a priority.  It lies up-ice of the green-diamond find and carries a near-source kimberlitic indicator minerals signature from glacial till sampling.   The Company has also been conducting a review of its exploration assets in the area which include the diamondiferous Seitaperä pipe (Finland’s largest, c.6.9 ha) and the Riihivaara kimberlite/olivine lamproite discovery. 

The Lahtojoki Diamond Deposit 

In June 2025 Karelian was granted a mining concession certificate by Tukes (the Finnish Mining Authority) which formally entitles the company to utilise the minerals within the mining concession area.   This was a very important milestone as it allows the Company to progress to the next stage of work on the mining concession area and accordingly mining rights related to the Lahtojoki mining concession.  The Lahtojoki diamond mining project comprises a mining concession covering 71 hectares (c. 176 acres) including a kimberlite pipe with a surface area of 1.6 hectares (c. 4 acres). The Company has been working with the relevant authorities to achieve the various milestones required for the granting of the mining concession.   In addition to this, the focus of the Company’s efforts over the last number of months on this project  has been on exploring possibilities in terms of securing appropriate strategic or partnership finance to progress development.

Financial Review

The loss after taxation for the half year ended 30 November 2025 was €165,591 (30 November 2024: loss of €121,186) and the net assets as at 30 November 2025 were €10,183,925 (30 November 2024: €9,993,699).   In June 2025 the Company raised £185,000 by way of a placing of new shares at an issue price of 0.75 pence per share and is currently considering a number of financing and funding options for the current year which, if successful, would provide the Company with capital to further the work programmes on the above noted projects.

Directors and Staff

I would like to thank my fellow directors, staff and consultants for their support and dedication, which has allowed the Company to continue to develop. Their support and commitment is key to the success of the Company.

Outlook

The Company is looking forward to the progressing of work programmes on its highly prospective Nickel, Copper and Platinum Group Element targets in Northern Ireland (including a tangible Copper target).   A clear work programme and strategy have been identified for the Company’s exploration assets in Finland and the Company is also hopeful of arriving at the end of the permitting process for the Lahtojoki diamond deposit which will enable the Company to progress to mine development on securing of appropriate finance. 

Finally, I would like to take this opportunity to place on record my appreciation for the continued support shown by both current and former directors in terms of remuneration deferral.  This is a significant number in the context of the Company’s balance sheet and consideration is currently being given to a potential re-structuring of these amounts.

Yours faithfully,

Brendan McMorrow
Chairman

2024

Share capital

The share capital comprises the nominal value share capital issued for cash and non-cash consideration. The share capital also comprises deferred share capital. The deferred share capital* arose through the restructuring of share capital which was approved at an Annual General Meeting held on 9 December 2016.

Authorised share capital:

The authorised share capital at 30 November 2025 compromised 7,301,301,041 ordinary shares of €0.00025 each, and 317,785,034 deferred shares of €0.00999 each* (€5,000,000), (30 November 2024: 7,301,301,041 ordinary shares of €0.00025 each, and 317,785,034 deferred shares of €0.00999 each* (€5,000,000)).

* Capital reorganisation:

Following approval at an Annual General Meeting (“AGM”) held on 9 December 2016, the Company reorganised its share capital by subdividing and reclassifying each issued ordinary share of €0.01 as one ordinary share of €0.00001 each and one deferred share of €0.00999 each.  The Deferred Shares have no right to vote, attend or speak at general meetings of the Company and have no right to receive any dividend or other distribution, and have only limited rights to participate in any return of capital on a winding-up or liquidation of the Company, which will be of no material value. No application was made to the London Stock Exchange for admission of the Deferred Shares to trading on the AIM.

Consolidated shares:

On 21 December 2017, the Company passed a Special Resolution at the Company’s AGM, that all of the ordinary shares of €0.00001 each in the capital of the Company, whether issued or unissued were consolidated into New Ordinary Shares of €0.00025 each in the capital of the Company (“consolidated shares”) on the basis of one consolidated share for every 25 existing ordinary shares. Following the consolidation of the ordinary shares on 21 December 2017, the warrants in issue were consolidated into one consolidated warrant for every 25 existing warrants. The exercise price in relation to the warrants was also adjusted at this time (see Note 2).

Share and Warrant issues during the period:

During the period ended 30 November 2025, the Company raised €217,154 (£185,000) before expenses through the issue of 24,666,666 new ordinary shares at a price of £0.0075 per ordinary share.

Share premium

The share premium comprises the excess consideration received in respect of share capital over the nominal value of the shares issued as adjusted for the costs of share issue in line with the Company’s accounting policies.

Share based payment reserve

The share based payment reserve comprises of the fair value of all share options and warrants which have been charged over the vesting period, net of amounts relating to share options and warrants forfeited, exercised or lapsed during the period, which are reclassified to retained earnings.

Retained losses

This reserve represents the accumulated losses incurred by the Company up to the condensed statement of financial position date.

Accounting policies

1. Reporting entity

Karelian Diamond Resources plc (the “Company”) is a company domiciled in Ireland.

Basis of preparation and statement of compliance

The condensed financial statements for the six months ended 30 November 2025 are unaudited.

The condensed financial statements have been prepared in accordance with International Accounting Standard (“IAS”) 34: Interim Financial Reporting.

The condensed financial statements do not include all the information and disclosures required in the annual financial statements, and should be read in conjunction with the Company’s annual financial statements as at 31 May 2025, which are available on the Company’s website - www.kareliandiamondresources.com. The accounting policies adopted in the presentation of the condensed financial statements are consistent with those followed in the preparation of the Company’s annual financial statements for the year ended 31 May 2025.

The condensed financial statements have been prepared under the historical cost convention, except for derivative financial instruments which are measured at fair value at each reporting date.

The condensed financial statements are presented in Euro (“€”). The Euro is the functional currency of the Company.

The preparation of condensed financial statements requires the Board of Directors and management to use judgements, estimates and assumptions that affect the application of policies and reported amounts of assets, liabilities, income and expenses. Actual results may differ from those estimates. Estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognised in the financial period in which the estimate is revised and in any future financial periods affected. Details of critical judgements are disclosed in the accounting policies detailed in the annual financial statements.

The financial information presented herein does not amount to statutory financial statements that are required by Chapter 4 part 6 of the Companies Act 2014 to be annexed to the annual return of the Company. The statutory financial statements for the financial year ended 31 May 2025 were annexed to the annual return and filed with the Registrar of Companies. The audit report on those financial statements was unqualified.

These condensed financial statements were authorised for issue by the Board of Directors on 26 February 2026.

Going concern

The Company recorded a loss of € 165,591 for the six-month period ended 30 November 2025 (30 November 2024: loss of €121,186). The Company had net current liabilities of €1,996,197 at that date (30 November 2024: €1,902,276).

The Board of Directors have considered carefully the financial position of the Company and in that context, have prepared and reviewed cash flow forecasts for the period to 28 February 2027. As set out further in the Chairman’s statement, the Company expects to incur capital expenditure in 2026, consistent with its strategy as an exploration company. In reviewing the proposed work programme for exploration and evaluation assets, the results obtained from the exploration programme and the prospects for raising additional funds as required, the Board of Directors are satisfied that it is appropriate to prepare the financial statements on a going concern basis.

Statement of compliance

The Company’s financial statements have been prepared in accordance with IFRS as adopted by the European Union (“EU”).

Exploration and evaluation assets relate to expenditure incurred in the development of mineral exploration opportunities. These assets are carried at historical cost and have been assessed for impairment in particular with regard to the requirements of IFRS 6: Exploration for and Evaluation of Mineral Resources relating to remaining licence or claim terms, likelihood of renewal, likelihood of further expenditure, possible discontinuation of activities as a result of specific claims and available data which may suggest that the recoverable value of an exploration and evaluation asset is less than its carrying amount. 

The Board of Directors have considered the proposed work programmes for the underlying mineral resources. They are satisfied that there are no indications of impairment.

The Board of Directors note that the realisation of the intangible assets is dependent on further successful development and ultimate production of the mineral resources and the availability of sufficient finance to bring the resources to economic maturity and profitability.

  1. Commitments and Contingencies

At 30 November 2025, there were no capital commitments or contingent liabilities (31 May 2025: No capital commitments or contingencies liabilities). Should the Company decide to develop the Lahtojoki project, an amount of €40,000 is payable by the Company to the vendors of the Lahtojoki mining concession.

  1. Convertible Loan

On 26 May 2023, the Company entered into a convertible loan note agreement for a total amount of €129,550 (£112,500) with Conroy Gold and Natural Resources plc which is both a shareholder in the company and has a number of other connections as set out in Note 14 to the audited financial statements for year ended 31 May 2025. The convertible loan note is unsecured, had a term of 18 months and attracts interest at a rate of 5% per annum which is payable on the maturity or conversion of the convertible loan. The conversion price is at a price of 5 pence per ordinary share. The shareholder has the right to seek conversion of the principal amount outstanding on the convertible loan note and all interest accrued at any time during the term.   The convertible term has passed but the loan continues in place on an informal basis on the same terms and is classified as a current liability for the period ended 30 November 2025.  The Company is in discussions with the note holder to extend the term of the loan note.

€10,304 was recorded as a derivative liability attached to the total convertible loan note above and the net amount of €119,246 was initially recorded as the value of the convertible loan at 31 May 2023. The loan incurred interest of €3,240 in the current period (31 November 2024: €3,240).

  1. Trade and other payables: amounts falling due within one year

Included in the payables figure of €1,987,806 is an amount of €1,660,704 in respect of amounts owing to both current and former directors of the Company who provide continuing support to the Company through renewing annually a commitment not to seek payment of the amounts owed unless the Company is in a position to discharge them.

  1. Warrant liabilities

The Company holds Sterling based warrants. The Company estimates the fair value of the sterling-based warrants using the Binomial Lattice Model. The determination of the fair value of the warrants is affected by the Company’s share price along with other assumptions.

As part of the share issue in July 2024, the Company issued 11,799,997 warrants at a price of GBP 3 pence per warrant.   These warrants expired in July 2025.   There are 43,076,667 warrants to acquire shares at a price of GBP 1.5p per share still in issue, expiring in February 2027. The fair value of these warrants was €14,607 as at 30 November 2025.   The movement in fair value of warrants including the effect of warrant expiry resulted in a non-cash gain of €18,272 in the period.
