Rome Resources plc announced Friday that specialist geological work at its Mont Agoma prospect within the Bisie North project has uncovered promising new areas for tin and copper exploration. The analysis separates the site’s rock sequences into five distinct zones using trace element signatures, with most mineralization concentrated above a key marker horizon atop Zone 3.

Chemostrat, the consultancy hired by Rome Resources, examined the company’s geological and assay data from Mont Agoma. Their method distinguishes seemingly identical rock layers through ratios like thorium to scandium. This approach revealed predictable patterns in the deposit’s structure.

Tin prospectivity spikes in a southeast extension above the Top Zone 3 marker, an area largely untouched by drilling. Copper shows similar potential to the northwest. Officials at Rome Resources called these high-priority targets for future resource expansion.

The deposit remains open in multiple directions. Rome Resources plans to pursue these opportunities as part of its broader Bisie North strategy, though current drilling efforts center on the Kalayi program. Mont Agoma now offers a pipeline of defined drill sites.

Paul Barrett, the company’s chief executive officer, said the interpretation marks a major advance in understanding Mont Agoma. “It has identified exciting new areas prospective for both tin and copper mineralization,” Barrett stated. He described the site as a large polymetallic copper-tin-zinc system with substantial upside.

Rome Resources, listed on London’s AIM market under RMR, focuses on tin and copper in the DRC. The firm scheduled an investor call for Thursday, February 19, 2026, at 12:00 p.m. GMT to discuss Kalayi drilling progress and Mont Agoma plans. Registration is available on the company’s website.

Dr. Paul Armitage, a qualified geologist and consultant to Rome Resources, reviewed the technical details. Armitage, a Fellow of the London Geological Society and member of the Institute of Materials, Minerals and Mining, approved the announcement under NI 43-101 and AIM guidelines.

The work builds on Rome Resources’ efforts to refine its exploration model. By tying mineralization to specific horizons, the company gains better tools to predict and target new finds. Investors will watch how these targets fit into upcoming campaigns.
