Rome Resources (LSE:RMR) has announced additional high-grade tin results from deep drilling at the Kalayi prospect, part of its Bisie North project in the Democratic Republic of Congo.
The latest phase of core drilling, covering 1,602 metres, indicates that the near-surface high-grade tin mineralisation defined in the maiden resource continues at depth. Several new drill holes intersected multi-metre zones grading above 3% tin, including intervals exceeding 5%. Among the highlights were 11 metres at 3.43% tin and 4 metres at 7.50% tin.
Management noted that the thickness and grade of these intercepts compare favourably with production from Alphamin Resources’ nearby Mpama North mine. With tin prices remaining firm, the results reinforce confidence in Kalayi’s potential scale and geological continuity.
The company said the latest data supports its structural interpretation of the deposit and will feed into an updated resource estimate expected in the coming months. At the same time, advanced modelling work at the Mont Agoma prospect is shaping the next drilling campaign. Management plans to update investors on progress and forthcoming activities through an interactive call scheduled this week.
Despite the operational progress, the company’s broader outlook remains challenged by financial pressures. Rome Resources is pre-revenue, reporting widening losses and sustained negative free cash flow, underscoring ongoing funding risk. Technically, the shares face mild headwinds from a weak longer-term trend and a negative MACD signal. Valuation metrics are also limited in usefulness given negative earnings and the absence of dividend support.
