Rome Resources (RMR ) has completed its latest round of drilling at the Kalayi prospect within the Bisie North project in the Democratic Republic of Congo, located approximately 8 km from the world-class Alphamin Mpama tin mine complex.
Drilling operations completed on 4 April 2026, having been active since December 2025.
The Kalayi prospect accounted for 91% of the total 3,050 metres drilled.
At this point, Rome believes that drilling confirms the presence of high-grade tin mineralisation which continues at depth and across multiple holes, supporting its structural model.
This drill campaign has delivered the widest and strongest intercepts from the prospect to date. Highlights of the recent drilling campaign include multiple highly encouraging tin intercepts which have been provisionally assessed using a handheld XRF device.
An updated resource estimate is expected in the coming weeks.
"The tin intercepts encountered in this recent drilling campaign underscore Kalayi's potential as an extensive high grade tin deposit situated only eight kilometres from a mine producing over 7% of the world's tin,” said Paul Barrett, chief executive of Rome Resources.
“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. 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."

The confirmation will be in the assay results, but so far the indication is that Rome will shortly be able to deliver a significant boost to the existing resource at Kalayi. The proximity of the project to one of the world’s most significant existing tin mines greatly enhances the potential for eventual development. Newsflow over the coming weeks will be very interesting.
