The scope of work covers both the Kalayi and Mont Agoma prospects and includes the generation of mineral resource models and reporting in accordance with CIM guidelines. The results will be documented in an NI 43-101 Technical Report, suitable for LSE-AIM disclosure and will include revieing 3D block models, incorporating grades and estimating tonnage. In addition, an assessment will be made of the prospects for eventual economic extraction. A previous NI 43-101 Technical Report was completed for Rome by MSA in 2024. Following extensive drilling since then, sufficient data has now been generated to support the creation of three dimensional mineralisation models for both prospects. Completion of the maiden MRE is targeted for around the end of June 2025 at which point a summary will be released to the market and the full report available on the Company's website. Rome is currently undertaking an aggressive deep drilling programme at Mont Agoma, with three rigs in operation targeting deeper tin mineralisation beneath the shallower copper-zinc zones. Given strong momentum in the field, an update to the initial maiden MRE is expected following receipt of new assay results from the current campaign. In addition, the Company will put out an update on pre-assay drill results when available, the first being on completion of the current three drill holes in the coming days. Paul Barrett, Chief Executive Officer of Rome Resources Plc, commented: "With three rigs currently operating at Mont Agoma, we are making rapid progress in testing what we believe is a large-scale, high-value copper-tin-zinc-silver system. The data collected so far is robust enough to support our maiden resource estimates for both Kalayi and Mont Agoma, and we are pleased to appoint MSA to carry out this important milestone for the Company." "The geology is shaping up as we had hoped - with copper and zinc dominant near surface and tin strengthening at depth - confirming the zonation model we are targeting. This resource will be our first formal step in defining scale and value at Bisie North, and we plan to follow it with a further updates once assay results from our current deeper drilling campaign are available."
