Kalayi Drilling Continues to Return High-Grade Tin Intercepts

 

Rome Resources plc (AIM: RMR), the DRC-focused tin and copper explorer, is
pleased to provide an update on its drilling operations at its Kalayi prospect
within its Bisie North project in the Democratic Republic of Congo ("DRC"),
located approximately 8 km from the world-class Alphamin Mpama tin mine
complex.  Recent drilling continues to confirm the presence of high-grade tin
mineralisation, including strong intercepts encountered at depth beneath the
existing Mineral Resource Estimate ("MRE").

 

Status of Kalayi Drilling Programme

 

Since the last update announced on 16(th) February 2026, two drill rigs have
continued to operate at the Kalayi Bisie North prospect as part of the
Company's post maiden Mineral Resource Estimate ("MRE") drilling programme.
Drilling at Kalayi has continued to demonstrate that near-surface high-grade
tin mineralisation continues at depth and across multiple holes within the
deposit.  Almost 2,700m of core has been recovered since drilling operations
re-commenced at the very end of 2025.

 

The programme is now nearing completion, with the final two holes currently
being drilled.  Approximately 600kg of drill samples have been dispatched and
shipped to ALS Laboratories in Johannesburg for assay work, in addition to the
360kg previously shipped, comprising samples from drill holes up to and
including KBDD028.  Utilising on-site portable XRF, Rome Resources can
confirm drilling at Kalayi is delivering high-grade tin mineralisation across
multiple holes and continues to support the Company's structural model for the
deposit.

 

Initial on-site portable XRF results for Kalayi drill holes KBDD028 to KBDD030
are summarised below.

 

·    KBDD029: 10m at 1.3% Sn from 220m including 5m at 2.3% Sn from 223m;

·    KBDD028: 1m at 5.4% Sn from 32m, 1m at 2.0% Sn from 40m and 1m at
4.1% Sn from 45m and;

·    KBDD030: 4m at 1.0% Sn from 47m and 5m at 1.3% Sn from 59m including
1m at 6.6% Sn.

 

With tin currently trading at approximately US$50,000 per tonne, the grades
encountered at Kalayi continue to demonstrate the strong potential value of
the mineralised system.

 

Use of XRF for initial results

 

The portable XRF currently used at Bisie North is a Bruker S1 Titan model.
Readings represent averages of 60-second continuous analysis along 1m sections
of core. The X-ray beam is emitted through an active area of 20mm(2) and
penetrates up to several millimetres into the drill core.

 

The metal grades determined by the portable XRF are indicative only, though
they are calibrated against known standard samples. They should not be relied
upon for resource estimation. Samples from completed drillholes will be
submitted for laboratory assay, with results to be reported in due course.

 

Paul Barrett, Chief Executive Officer of Rome Resources, commented:

 

"We are very pleased with the continued success of the Kalayi drilling
programme. The latest intercepts continue to demonstrate that high-grade tin
mineralisation persists at depth beneath the existing resource, validating our
structural model for the deposit and reinforcing the potential for resource
expansion.

 

We look forward to incorporating the resulting assays from this programme into
the Company's next Mineral Resource Estimate update for Kalayi as we continue
our ongoing discussions with potential strategic partners regarding
development pathways for the asset."
