Rome Resources Plc (AIM:RMR, FRA:33R) announced it has wrapped up drilling at its Kalayi prospect in the Democratic Republic of Congo, with early readings pointing to what the company believes are its strongest tin intercepts there to date as it works toward a fresh resource estimate.
The AIM-listed explorer said the latest campaign ran from December 2025 to 4 April and covered 17 holes for a total 3,050 metres.
Kalayi accounted for 91% of drilled metres, targeting near-surface high-grade tin mineralisation and its continuation at depth within the Bisie North project, around 8 kilometres from Alphamin’s Mpama tin mine complex.
Rome said portable XRF readings from the programme support its structural model, with high-grade tin mineralisation encountered across multiple holes.
It added that the top five intercepts from the current campaign exceeded the maximum “richness” seen in earlier drilling, based on a comparative measure of intercept width multiplied by tin percentage.
Chief executive Paul Barrett said the latest intercepts “underscore Kalayi's potential as an extensive high-grade tin deposit”, while final assays are still pending.
"The tin intercepts encountered in this recent drilling campaign underscore Kalayi's potential as an extensive high-grade tin deposit," chief executive Paul Barrett said.
"While final assays are pending, these early indicators provide a compelling case for Kalayi's economic potential and suggest a clear step forward compared to previous drilling campaigns."
Barrett added: "Over the coming weeks, as assays are received and incorporated into the geological model, we expect to advance the proposed Mineral Resource Estimate update and continue to assess future development pathways for Kalayi, both technical and commercial."
