Rome Resources Highlights Deep High-Grade Tin Potential at Bisie North

Rome Resources (LSE:RMR) has reported positive signs of high-grade tin mineralisation at depth from continued drilling at the Kalayi prospect, part of its Bisie North project in the Democratic Republic of Congo. The update follows the project’s inaugural mineral resource estimate published in October 2025. Recent drilling returned strong handheld XRF readings, notably 2 metres grading an indicative 8.3% tin from a depth of 74 metres in drill hole KBDD023, alongside further intervals showing tin and copper mineralisation across additional holes.

The latest drilling results support the company’s geological interpretation that high-grade tin zones extend beyond previously explored depths. Rome Resources emphasised that the portable XRF readings are preliminary and require confirmation through laboratory assays. However, the results strengthen confidence in the potential presence of deeper tin-rich mineralisation, as the company continues drilling activities at Kalayi.

Looking ahead, Rome plans to resume work at the Mont Agoma prospect, where exploration will focus on identifying deeper tin mineralisation beneath an already recognised polymetallic system. Success at both Kalayi and Mont Agoma could support expansion opportunities and improve the long-term development outlook for the broader Bisie North project.

From a financial perspective, Rome Resources continues to face challenges linked to its pre-revenue status, widening losses, and ongoing negative free cash flow, highlighting explained reliance on future funding. Market technical indicators also reflect mild downward pressure, with a weak longer-term share trend and a negative MACD signal. Additionally, valuation metrics remain limited in usefulness due to negative earnings and the absence of dividend payments.
