Rome Resources boosts Kalayi tin resource by 45%

Rome Resources Plc, a critical minerals explorer operating in the Democratic Republic of Congo, has reported a 45% increase in the estimated tin content at its Kalayi deposit.
Kalayi, which forms part of the Bisie North project in eastern DRC, now hosts an inferred resource of 460,000 tonnes at a grade of 1.47% tin, equating to approximately 6,760 tonnes of contained metal.
A mineral resource estimate represents a geologist's quantitative assessment of the metal content and concentration-referred to as grade-within a given deposit.
The updated figure reflects a 45% uplift in contained tin compared with the maiden estimate published in October 2025, underpinned by a 32% increase in tonnage and a 10% improvement in grade.
It is uncommon for a resource expansion to yield higher average grades, yet Kalayi has achieved exactly that---with grade rising from 1.33% to 1.47% tin, alongside the tonnage gain.
Kalayi is one of two advanced-stage targets within the Bisie North portfolio. The other, Mont Agoma, is a distinct polymetallic system that hosts a maiden resource of 3.16 million tonnes grading 1.45% copper, along with by-product zinc, tin, and silver.
