Rome Resources plc

("Rome Resources", the "Company" or the "Group")

Placing to raise £1.9 million

and

Mobilisation for Drilling Operations

Rome Resources (AIM: RMR), the DRC-focused tin and copper explorer, announces that it has conditionally raised gross proceeds of £1.9 million through a placing (the "Placing") which was upsized following strong investor demand of 950,000,000 new ordinary shares ("Placing Shares") of 0.1 pence each in the share capital of the Company ("Ordinary Shares") to new and existing institutional and other investors ("Placees") at an issue price of 0.2 pence per new Ordinary Share (the "Placing Price").

The placees in the Placing will, upon Admission (as defined below) be issued with one warrant to subscribe for one new Ordinary Share for every Placing Share, with each Warrant entitling the holder to acquire one new Ordinary Share at a price of 0.4 pence at any time in the three-year period from issue (the "Warrants"). The Warrants are non-transferable by the holders without the prior consent of the Company. The Warrants will be in certificated form and none of the Warrants will be admitted to trading on AIM or any other stock exchange.

The Company is also pleased to announce it will mobilise BAC Helicopters and drilling crews to the Bisie North site to commence drilling a targeted programme, details of which are set out below, in the coming weeks.

Placing highlights

· A Placing to raise £1.9 million (before expenses) at the Placing Price of 0.2p pence per Placing Share.

· The proceeds of the Placing will be deployed to undertake Rome's next drilling programme at the Bisie North Project.

· Oak Securities (a trading name of Merlin Partners LLP) ("Oak") is acting as Broker in respect of the Placing.

· The Placing Price is equal to the closing mid-market price of 0.20 pence per Ordinary Share on 18 November 2025 (the "Closing Price"), being the latest practicable business day prior to the publication of this Announcement.

· The Placing and the issue of the Warrants are expected to be conducted utilising the Company's existing share authorities to issue and allot securities on a non-pre-emptive basis, granted at the general meeting of the Company on 30 July 2025.

Use of Proceeds

The net proceeds of the Placing will be used to support the mobilisation and execution of a new drilling programme designed to test the highest-priority targets defined in the Company's maiden Mineral Resource Estimate (MRE) and subsequent geological modelling:

· Several deep drillholes, split between the Kalayi and Mont Agoma prospects.

· Testing the deeper high grade tin zones at Kalayi, beneath existing intercepts.

· Testing the new eastern tin zone in Mont Agoma along with the deeper tin-dominant portions of the main tin/copper system.

· These drilling targets collectively represent potential for an addition 53kt and 144kt of contained tin resource

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

"The Board is highly encouraged by the technical foundations laid by the recent maiden Mineral Resource Estimate, which clearly highlights the high-grade potential at both Kalayi and Mont Agoma. We are now looking forward immensely to testing the high grade tin potential of Kalayi deep, a key upside indicated by the recent Maiden MRE. In addition, drilling at Mont Agoma, including the new eastern tin zone of Mont Agoma that was not included in the MRE, will test the potential for tin beneath the copper-rich upper levels of the system and offers significant upside potential for Mont Agoma.

Drilling is likely to commence in approximately two weeks, following mobilisation back to site of the Airbus AS350 support helicopter. We anticipate a 3-4 month programme, targeting between 53kt and 144kt of tin resource potential. Success in this campaign will underpin a resource update and a broader strategic review. Separately, we note the recent signing of the M23/DRC peace agreement, which will pave the way for further improvements in the security of the region."

Forward Drilling Programme

Kalayi

Kalayi, located approximately 10km northwest of Alphamin's Bisie Mine, hosts three confirmed high grade tin shoots. Historical drilling includes significant high grade intercepts such as 2.5m at 3.4% Sn, 0.4m at 12.9% Sn and 0.5m at 7.5% Sn, all at less than 80m depth. 

As demonstrated at the nearby Bisie Mine, widths of high grade tin intercepts typically expand dramatically below about 200m depth. Accordingly, the Kalayi forward programme concentrates on drilling beneath the proven high grade tin intercepts in order to evaluate how these zones evolve at depth. Several holes averaging 300m depth will be drilled at Kalayi to test the vertical expansion of these zones.

Mont Agoma

The Mont Agoma polymetallic deposit is rich in copper, zinc and tin with ancillary silver. The recent Maiden Mineral Resource identified significant resource potential in all four commodities in the relatively shallow drilled section of the 200m wide mineralised corridor. 

· Drilling will test deeper sections of the main zone, where tin is expected to become dominant at depth, consistent with global tin-copper systems.

· Additionally, the programme will also target the Mont Agoma Eastern Tin Zone where hole MADD030A intersected a 23m tin zone with a grade of 0.46% Sn, including inter alia 1m at 1.56% Sn and 1.6m at 1.42% Sn with less copper than the main Mont Agoma zone

This intercept was not included in the MRE, and consequently, part of the forward programme will test the continuation of this zone at depth, as it is expected to run sub-parallel to a major strike slip fault that separates the eastern zone from the main zone.

Summary

The exploration targets being drilled in the forward campaign represent a potential for between 53kt and 144kt of additional tin resource. Success with this programme will transform the project and drive the strategic review of options going forward.

Details of the Placing

The Placing comprises the issue of 950,000,000 new Ordinary Shares (the "Placing Shares") at the Issue Price to conditionally raise £1.9 million before expenses for the Company

When issued, the Placing Shares will represent approximately 13.5 per cent of the enlarged share capital of the Company and will rank pari passu with the existing Ordinary Shares. The Company has agreed to issue Oak with 57,000,000 fully transferable warrants exercisable at the Placing Price at any time until three years following Admission (as defined below).

The Placing is not being underwritten by Oak Securities or any other person.

Admission to trading on AIM

The Placing is conditional upon the receipt of funds and Admission (as defined below) becoming effective.

Application will be made to the London Stock Exchange plc for admission of the Placing Shares to trading on AIM ("Admission"). Admission is expected to occur on or around 25 November 2025.
