Increased interests in DRC, Director appointment

Rome Resources plc (AIM: RMR), the DRC-focused tin and copper explorer, announces that it has entered into non-binding heads of terms to further increase its ownership interests in exploration permit PR 15130 ("PR 15130") and mineral exploration permit PR 13274 ("PR 13274").

In addition, further to the Company's announcement on 3 September 2025, Stephane Mutombo Irung has been appointed as a non-executive director to the board of Rome Resources (the "Board"). In line with the Company's announcement on 11 December 2025, the process to recruit an additional non-executive director to the Board continues and a further update will be issued when appropriate.

Proposed Acquisitions highlights

• Opportunity to consolidate the Company's interests in its existing DRC projects;
• Proposed consideration for the Proposed Acquisitions is expected to be principally share-based; and
• If concluded, the Proposed Acquisitions is expected to result in an uplift of approximately 60 per cent. in the Company's net inferred resources, with the planned updated Mineral Resource Estimate having much greater value impact thereafter.

Rome Resources currently holds a 51 per cent. interest in Mont Agoma SARL ("Mont Agoma"), which in-turn is the current sole legal owner of PR 15130. The remainder of Mont Agoma is owned 19 per cent. by CoTinCo Minerals Projects International LLC and 30 per cent. by PALM Constellation SARL ("PALM")

Separately, Rome Resources holds a 71 per cent. interest in MediDoc RD Congo SAR ("MRDC"), which in-turn holds a 72.5 per cent. interest in Kalayi Tin SARL ("Kalayi"). Kalayi is the current sole legal owner of PR 13274. The remainder of Kalayi, being 27.5 per cent, is owned by Jean-Felix Mupande's ("JFM").

Rome Resources has entered non-binding heads of terms with PALM Constellation SARL ("PALM") to acquire PALM's 30 per cent. interest in Mont Agoma. PALM is owned by Messrs Lukusa Kaseba (60 per cent.) and Bilali Maganga (40 per cent.) (together the "Mont Agoma Acquisition").

In consideration for the Mont Agoma Acquisition, it is currently proposed that Rome Resources will issue PALM up to 600,000,000 new ordinary shares of 0.1 pence each in the share capital of the Company ("Ordinary Shares"), of which up to 300,000,000 Ordinary Shares are currently expected to only be issued if Mont Agoma achieves either (i) a drill intercept of at least 20 metre true thickness and a verified assay average tin grade of more than 1.8 per cent; or (ii) a drill intercept of at least 30 metre true thickness and a verified assay average copper grade of more than 4 per cent. In addition, Rome Resources is currently expected to grant PALM a 2 per cent net smelter return royalty over any development at Mont Agoma (the "Mont Agoma Royalty").

PR 13274

In addition, Rome Resources, through its subsidiary MRDC, has entered non-binding heads of terms with JFM to acquire JFM's 27.5 per cent. interest in Kalayi (together the "Kalayi Acquisition", and together with the Mont Agoma Acquisition, the "Proposed Acquisitions").

In consideration for the Kalayi Acquisition, it is currently proposed that Rome Resources will issue JFM up to 600,000,000 new Ordinary Shares, of which up to 300,000,000 Ordinary Shares are currently expected to only be issued if Kalayi achieves a drill intercept of at least 20 metre true thickness and a verified assay average tin grade of more than 1.8 per cent. In addition, Rome Resources is currently expected to grant JFM a 2 per cent net smelter return royalty over any development at Kalayi (the "Kalayi Royalty").

It is currently anticipated that any new Ordinary Shares to be issued pursuant to the Proposed Acquisitions will be issued pursuant to the Company's existing authorities to issue and allot equity securities granted at the general meeting of the Company on 2 April 2026.

Potential related party transactions

PALM currently holds a 30 per cent. interest in Mont Agoma, a subsidiary of Rome Resources. In addition, JFM currently holds a 27.5 per cent interest in Kalayi, also a subsidiary of Rome Resources. Accordingly, both PALM and JFM are related parties pursuant to the AIM Rules for Companies ("AIM Rules"). Should binding documentation be entered into in relation to the Proposed Acquisitions, the Proposed Acquisitions will likely constitute related party transactions for the purposes of Rule 13 of the AIM Rules. The Company will make a further announcement through a Regulatory Information Service, as appropriate.

Paul Barrett, Chief Executive Officer of Rome Resources, commented:

"The proposed acquisition of these additional interests has long been a goal of Rome Resources' management and this proposed pair of transactions, being principally share-based, represents excellent value for money for shareholders. The proposed acquisitions, if concluded, are expected to result in an uplift of approximately 60 per cent. in the Company's net inferred resources, with the planned updated Mineral Resource Estimate having much greater value impact thereafter.

Additionally, we are delighted Stephane is coming onboard now as he will add a further layer of DRC experience to the team going forward."
