Vast Resources plc
("Vast" or the "Company")

Update on Proposed Acquisition of Gulf International Minerals Limited and

Extension of Loan Facilities

Vast Resources plc announces that, further to the proposed Acquisition announced on 22 December 2025, it has entered into an amendment agreement with Bay Square Pacific Ltd to extend the long stop date in respect of the SPA from 31 March 2026 to 5 May 2026 ("Longstop Date Extension"). 

Transaction Update

The Company notes that the Proposed Transaction is well advanced with due diligence largely completed. Following the anticipated formal confirmation by the Government of Tajikistan of organisational changes in Aprelevka in order to ensure a smooth transition post completion of the Proposed Transaction, and subject to completion of the associated Placing, the Company expects to be in a position to publish an Admission Document in April 2026.

Diamond Update

The Company notes that the current geopolitical climate in the Middle East has resulted in delays of certain diamond sales, which were originally scheduled to be completed in Dubai. The Company is in advanced discussions regarding alternative sales channels in Antwerp and expects to conclude these arrangements in the coming weeks. The Company will provide further updates to the market in relation to the Proposed Transaction and the diamond sales as and when appropriate.

Loan Facility Update

Further to the announcement of 12 February 2026, Vast confirms that it is in discussion with A&T Investments SARL and Mercuria Energy Trading SA to seek to agree to an extension of the terms of their respective loans until 30 April 2026, subject to continued progress being made on the Proposed Transaction. The Company intends to use the revenue from upcoming diamond sales, together with proceeds from the Placing in relation to the Acquisition, and proceeds from new offtake finance agreements and / or wider funding arrangements, to repay the Creditors in full. It is noted that, whilst the Board remains confident further Loan Facility Extensions can be agreed in order to support completion of the Proposed Transaction, there can be no guarantee as to the outcome of discussions in relation to the Loan Facility Extensions or that the Proposed Transaction will complete.

ABOUT VAST RESOURCES

Vast Resources plc is a United Kingdom AIM quoted mining company with mines and projects in Romania, Tajikistan, and Zimbabwe.

In Romania, the Company is focused on the rapid advancement of high-quality projects by recommencing production at previously producing mines.

The Company's Romanian portfolio includes 100% interest in Vast Baita Plai SA which owns 100% of the Baita Plai Polymetallic Mine, located in the Apuseni Mountains, Transylvania, an area which hosts Romania's largest polymetallic mines. The mine has a JORC compliant Reserve & Resource Report which underpins the initial mine production life of approximately 3-4 years with an in-situ total mineral resource of 15,695 tonnes copper equivalent with a further 1.8M-3M tonnes exploration target. The Company is now working on confirming an enlarged exploration target of up to 5.8M tonnes.

The Company also owns the Manaila Polymetallic Mine in Romania, which the Company is looking to bring back into production following a period of care and maintenance. The Company has also been granted the Manaila Carlibaba Extended Exploitation Licence that will allow the Company to re-examine the exploitation of the mineral resources within the larger Manaila Carlibaba licence area.

The Company retains a continued presence in Zimbabwe. The Company is re-engaging its future investment strategy in Zimbabwe and has commenced discussions with further mining concessions in-country alongside its wider portfolio.

Vast has an interest in a joint venture company which provides exposure to a near term revenue opportunity from the Takob Mine processing facility in Tajikistan. The Takob Mine opportunity, which is 100% financed, will provide Vast with a 12.25 percent royalty over all sales of non-ferrous concentrate and any other metals produced.

Also in Tajikistan, Vast has been contracted to develop and manage the Aprelevka gold mines on behalf of its owner Gulf International Minerals Ltd ("Gulf") under which Vast is entitled, inter alia, to 10% of the earnings that Gulf receives from its 49% interest in Aprelevka in joint venture with the government of Tajikistan. Aprelevka holds four active operational mining licences located along the Tien Shan Belt that extends through Central Asia, currently producing approximately 10,400oz of gold and 80,000 oz of silver per annum. It is the intention of the Company to assist in increasing Aprelevka's production from these four mines closer to the historical peak production rates of approximately 27,000oz of gold and 250,000oz of silver per year from the operational mines.
