Bisie North Drilling Update

Rome Resources plc (AIM: RMR), the DRC-focused tin and copper explorer, is pleased to provide an update on its drilling operations at its Bisie North project in the Democratic Republic of Congo ("DRC"), located just 8 km from the world-class Alphamin Mpama tin mine complex.

Status of Drilling Programme

We are pleased to report that two drill rigs are currently operating at Bisie North: one rig active at the Mont Agoma prospect and the second at the Kalayi prospect. This drilling activity forms part of the Company's post-maiden Mineral Resource Estimate ("MRE") drilling programme, details of which were announced on 23 December 2025. The maiden MRE confirmed that the target zones are part of a large polymetallic system, with Mont Agoma demonstrating a wide zone dominated by near-surface copper with tin grade anticipated to increase at depth, and Kalayi showing near-surface high-grade tin, open at depth and expected to increase in width and grade with depth.

Two holes have been completed, and a third hole is approaching its target depth. Initial findings are summarised below.

Initial on-site results from drillhole KBD019:

· Kalayi hole KBD019 was drilled to a total depth of 189.5 metres, having encountered significant tin mineralisation between 129 metres and 135 metres.

· Handheld XRF readings at 1-metre intervals across this 6-metre-wide zone average 1.6% tin (six readings ranging 0.02% to 3.94% including four readings above 1.4%).

· This interval is within a broader 26-metre-wide zone showing disseminated cassiterite between 114.0 metres and 140.7 metres depth, supporting the continuity of mineralisation at Kalayi.

· The drilling rig has since moved with drilling commenced at hole KBD020.

Mont Agoma drilling update:

· Drillhole MADD034 was drilled to 94 metres, serving as a control point for the structural model.

· Drillhole MADD035, drilled from the same pad location, is currently at approximately 190 metres depth and progressing within the main Mont Agoma mineralised zone. 

Sampling and Assays

The reported tin grades are derived from handheld XRF analyses. These are spot readings with an approximately 10-millimetre-wide analytical window and are indicative only. They should not be relied upon for any resource calculations. Samples from completed drillholes will be submitted for laboratory assay in due course, with results to be reported once received.

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

"We are encouraged by the early indications from this second phase of drilling at Kalayi, where the intersection of a tin-rich zone at depth is consistent with the Company's structural model and expectations for high-grade extensions beneath the known mineralisation.

"Drilling at Mont Agoma is also progressing well as we move toward the deeper parts of the system where we believe tin grades may strengthen. We look forward to regularly updating the market as drilling continues on both prospects and further results become available."
