Large Tin-Copper-Zinc System Confirmed at Bisie North, DRC

Rome Resources has announced a significant milestone in its exploration journey, confirming the presence of a large tin-copper-zinc system at its Bisie North project in the Democratic Republic of Congo (DRC). The company’s maiden mineral resource estimate (MRE), covering the Kalayi and Mont Agoma prospects, represents the first official quantification of mineral resources in this area. This achievement not only validates the geological potential of the Bisie North region but also opens up substantial opportunities for further discovery as exploration continues.

According to the results, the confirmed system is a multi-metallic body rich in tin, copper, and zinc, with only a small fraction of the license area drilled to date, primarily at depths between 220 and 250 meters. Early findings suggest that deeper and step-out drilling could significantly expand the known resource, potentially adding an estimated 102,000 to 260,000 tonnes of tin. Particularly promising is the Mont Agoma East zone, which contains a 23-meter near-surface section of high-grade tin mineralization. Notably, tin grades in this area appear to increase with depth, a geological pattern consistent with both Alphamin’s world-class Bisie mine, located nearby, and the renowned San Rafael deposit in Peru.

Rome Resources has outlined an ambitious plan to continue drilling and progressively update its resource estimates as new data becomes available. The company is also pursuing opportunities to increase its ownership in key exploration permits, specifically PR15130 and PR13274, which would strengthen its control over the project area. In parallel, management has initiated discussions with potential strategic partners to support the development phase, signaling growing investor interest in the DRC’s expanding tin sector.

The confirmation of this extensive polymetallic system at Bisie North positions Rome Resources as a rising player in Central Africa’s critical minerals market. With tin playing an increasingly vital role in electronics and renewable energy technologies, the project has the potential to contribute meaningfully to global supply chains. Moreover, the find reinforces the DRC’s standing as one of the world’s most resource-rich regions, attracting further international exploration activity. In the broader context, this discovery could stimulate local economic growth, promote infrastructure development, and bolster the DRC’s efforts to formalize and modernize its mining sector.

Mini-Glossary

• Maiden Mineral Resource Estimate (MRE): The first official calculation of a deposit’s size, grade, and metal content.
• Polymetallic system: A geological formation containing multiple valuable metals, such as tin, copper, and zinc.
• Step-out drilling: A technique used to test mineralization beyond the existing drilling area to expand known resources.
• High-grade: Refers to ore containing a high concentration of valuable minerals, making extraction more economically viable.
• Exploration permit: A government-issued license granting a company the right to explore for minerals within a defined area.
