What's Happening?
Rome Resources, an Aim-listed company, has concluded its drilling campaign at the Kalayi deposit within the Bisie North Project in the Democratic Republic of Congo (DRC). The company has received the final assay results, which will be incorporated into
an updated mineral resource estimate (MRE) expected in July. The current MRE, announced in November 2025, reported an inferred mineral resource of 330,000 tons grading 1.36% tin. The recent drilling aimed to enhance geological continuity and increase the tin content within the Kalayi resource. The campaign revealed broader mineralized zones, maintaining high-grade tin intervals, which are expected to strengthen the geological model. Notable drill intercepts include KBDD025 with 9.5 meters at 2.05% tin from 60 meters, and KBDD033 with 19.5 meters at 0.52% tin from 144 meters. The average grade of mineralization for samples above a 0.5% tin cutoff is 2.41%, potentially placing Kalayi among global tin projects with an average grade over 2%.
Why It's Important?
The completion of the drilling campaign and the anticipated updated MRE are significant for Rome Resources as they could lead to a substantial increase in the estimated tin content at the Kalayi deposit. This development is crucial for the company’s strategic plans, as it aims to transition from a small-scale exploitation permit to a full mining license. The results could enhance the company’s valuation and attract further investment, given the high-grade tin intervals reported. Additionally, the findings support the ongoing pilot tin mining project, which is expected to provide valuable geological and processing information for future development. The success of this project could have broader implications for the tin industry, potentially increasing supply and impacting global tin markets.
What's Next?
Rome Resources plans to finalize the updated MRE by July, which will incorporate the latest drilling results. The company is also advancing several parallel workstreams, including processing data from a recently completed airborne geophysical survey. This survey aims to improve the understanding of the Bisie mineralized system and identify additional exploration targets. The pilot tin mining project continues to progress, supporting the conversion to a full mining license. Additionally, exploration fieldwork is ongoing at the New Brunswick critical minerals project in Canada, which Rome Resources has an option over. These initiatives are expected to advance the Kalayi project towards development and enhance shareholder value.
