Aim-listed Rome Resources has reported that two drill rigs are currently operating at its Bisie North project, in the Democratic Republic of Congo (DRC), with one rig active at the Mont Agoma prospect and the other at the Kalayi prospect.

The company says this drilling activity forms part of its post-maiden mineral resource estimate (MRE) drilling programme, details of which were announced on December 23, 2025.

The maiden MRE confirmed that the target zones are part of a large polymetallic system, with Mont Agoma demonstrating a wide zone dominated by near-surface copper with tin grade anticipated to increase at depth, and Kalayi showing near-surface high-grade tin, open at depth and expected to increase in width and grade with depth.

The company notes that two holes have been completed and a third hole is approaching its target depth.

Kalayi hole KBD019 was drilled to a total depth of 189.5 m, having encountered significant tin mineralisation between 129 m and 135 m, with handheld X-ray fluorescence (XRF) readings at 1 m intervals across this 6 m wide zone average 1.6% tin.

The company explains that this interval is within a broader 26 m wide zone showing disseminated cassiterite between 114 m and 140.7 m depth, supporting the continuity of mineralisation at Kalayi.

The drilling rig has since moved, with drilling started at hole KBD020.

Additionally, at Mont Agoma, drillhole MADD034 was drilled to 94 m, serving as a control point for the structural model.

Rome notes that drillhole MADD035, drilled from the same pad location, is currently at about 190 m depth and progressing within the main Mont Agoma mineralised zone.

The reported tin grades are derived from handheld XRF analyses.

The company explains that these are spot readings with an about 10-mm-wide analytical window and are indicative only and should not be relied upon for any resource calculations.

Rome says samples from completed drillholes will be submitted for laboratory assay in due course, with results to be reported once received.

"We are encouraged by the early indications from this second phase of drilling at Kalayi, where the intersection of a tin-rich zone at depth is consistent with the company's structural model and expectations for high-grade extensions beneath the known mineralisation.

"Drilling at Mont Agoma is also progressing well as we move toward the deeper parts of the system where we believe tin grades may strengthen. We look forward to regularly updating the market as drilling continues on both prospects and further results become available,” says CEO Paul Barrett.
