Highlights

  • Rome Resources begins next phase of drilling at Bisie North, focusing on deeper mineralisation.
  • Maiden Mineral Resource Estimate highlights potential extensions of tin and copper zones.
  • Approximately 2,000 metres of drilling planned across Mont Agoma and Kalayi prospects.

Rome Resources plc (LSE:RMR), the DRC-focused tin and copper explorer, has commenced the next phase of drilling at its Bisie North project, located 8 km from Alphamin’s Mpama tin mine. Following a fundraise in November 2025, the Company has deployed two drill rigs at the Mont Agoma prospect, with plans to move to the Kalayi prospect.

The drilling programme aims to test deeper mineralisation beneath areas outlined in the maiden Mineral Resource Estimate (MRE). At Mont Agoma, drilling will focus on extending the Mont Agoma East zone and testing deeper sections of Mont Agoma West, where copper grades may transition to higher tin grades at depth. At Kalayi, the programme targets extensions beneath existing high-grade tin intercepts, following observations from Alphamin’s Mpama mine that thinner high-grade zones may widen at depth.

A total of approximately 2,000 metres of drilling is planned across 6–8 holes, with the programme expected to complete by the end of the first quarter of 2026. Core assay results will be used to update the MRE to include new intercepts from this campaign.

2025 Operational Overview
Since its AIM listing in July 2024 and the strategic investment by Stanvic Mining, Rome Resources completed a diamond drilling campaign across Bisie North, recovering a total of 5,143 metres of drill core from the Kalayi and Mont Agoma prospects.

The maiden MRE, prepared by The MSA Group (Pty) Ltd, reported:

  • Mont Agoma: 3.16 Mt at 1.45% Cu, 0.16% Sn, 2.72% Zn, 14.3 g/t Ag
  • Kalayi: 0.33 Mt at 1.36% Sn

Drilling to date has generally reached depths of 220–250 metres and covered only a portion of the prospective licence area, leaving scope for further discoveries both along strike and at depth. A newly intersected near-surface tin zone at Mont Agoma East, not included in the maiden MRE, has been prioritised in the current drilling campaign.
