Highlights

Agreement signed to sell the Company’s interest in the Horse Hill Oil Project.

Legal proceedings issued and served upon McKnight Resources AB for specific performance and breach of contract in relation to the Finnsbo Project in Sweden.

Horse Hill Sale

The Company has entered into a share purchase agreement with energy B plc (AQSE: NRBG) ("energy B") for the sale of the Company's entire 18.1% shareholding in Horse Hill Developments Ltd ("HHDL"), representing an effective 11.765% interest in Petroleum Exploration and Development Licence 137 ("PEDL 137") at Horse Hill, Surrey.

Under the terms of the agreement, Arkadian will receive cash consideration of £137,386 for its HHDL shares, comprising an initial non-refundable payment of £13,739 on execution of the agreement, which has now been paid, and the balance of £123,647 payable on Completion.

The cash consideration for the sale of Arkadian's HHDL shareholding has been agreed on the same pro rata economic basis as the consideration previously agreed by energy B to be paid to UK Energy plc (formerly UK Oil & Gas PLC) for the latter’s majority interest in Horse Hill.

In addition, on Completion energy B will grant Arkadian 400,000 warrants over ordinary shares in Energy B, exercisable at 12 pence per share for a period of three years, in consideration for the release of Arkadian's shareholder loan to HHDL.

Arkadian’s investment in HHDL, including its shareholder loan, is currently carried at nil in the Company's accounts.

Completion of the transaction will take place simultaneously with completion of energy B's acquisition of the majority interest in Horse Hill from UK Energy plc and remains subject, inter alia, to the required approval of the North Sea Transition Authority ("NSTA") in relation to PEDL 137. Energy B has advised that the relevant application was submitted to the NSTA on 30 September 2026.

A further announcement will be made upon completion of the transaction.

Finnsbo Project, Sweden

The Company confirms that it has commenced legal proceedings against McKnight Resources AB ("McKnight"), a private Swedish company and the holder of the Finnsbo 100 mineral exploration licence, in the Stockholm District Court, Sweden.

The proceedings arise from McKnight's purported termination of the Company's rights under the binding earn-in agreement relating to the Finnsbo Project and its subsequent failure to vest in Arkadian the 25% interest which the Company maintains it has duly earned through satisfaction of the agreed Stage 1 exploration expenditure requirement.

Notably, McKnight purported to terminate Arkadian's earn-in rights in November 2025 while the Company was in the midst of drilling the third and final hole of its programme at Finnsbo, notwithstanding that McKnight had itself actively assisted the Company in designing the programme, preparing the relevant permitting applications and getting drilling operations underway. The Board considers McKnight's actions in these circumstances, and its continuing refusal to recognise and give effect to Arkadian's contractual rights, to constitute serious and egregious breaches of contract.

Arkadian's primary claim seeks specific performance of the agreement. Alternatively, the Company seeks damages for breach of contract, together with interest and legal costs. The Board firmly believes that Arkadian has strong and compelling grounds for its claims.
