High-Grade Tin Intercepts at Depth at Kalayi:

Deep Drilling Programme Delivering Strong Results

 

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
at the Bisie North project in the Democratic Republic of Congo ("DRC"),
located approximately 8 km from the world-class Alphamin Mpama tin mine
complex.

 

The current drilling programme at Kalayi follows the Company's maiden Mineral
Resource Estimate ("MRE") and is specifically designed to test the
continuation of high-grade tin mineralisation at depth beneath the existing
resource.  As of 15(th) February 2026, a total of 1,602 metres of core
drilling has taken place on Kalayi during this current drilling campaign.

 

Recent drilling has confirmed the persistence of high-grade tin mineralisation
at depth below the maiden MRE, with multiple significant multi-metre
high-grade intervals intersected.

 

Deep Kalayi Drilling Results (XRF - indicative only)

 

Since the last update on 5 February 2026, two drill rigs have been operating
at the Kalayi Bisie North Prospect as part of the Company's post maiden MRE
drilling programme. Drilling at Kalayi has continued to successfully confirm
that near-surface high-grade tin mineralisation continues at depth, with four
new drillholes completed (nine in total at Kalayi) and a fifth approaching its
target depth. Initial on-site portable XRF readings are summarised below.

 

Initial on-site results (including average grades of mineralisation) from
drillholes KBDD024 to KBDD027 are presented below in order of increasing depth
tested, illustrating higher-grade intervals within deeper portions of the
system:

 

·    Kalayi hole KBDD026 encountered 1m @ 1.0% tin at 30 metres and 6m @
0.60 % tin at 35 metres depth;

·    Kalayi hole KBDD025 encountered 11m @ 3.43% tin from 60 metres depth
including 6m @ 5.14% tin from 65 metres depth;

·    Kalayi hole KBDD027 encountered 4m @ 7.50% tin from 75 metres depth
(Figure 1); and

·    Kalayi hole KBDD024 encountered 3m @ 2.64% tin from 116 metres depth.

 

Geological Context: Comparison with Mpama North Mine

 

Mpama North Mine, operated by Alphamin, lies approximately 8km to the south of
the Bisie North project and represents a strong geological analogue for
Kalayi.  At Mpama North 1  (#_ftn1) , the Main Vein of the Mpama Mine is
reported as being between 2 and 22 metres in thickness, with an average tin
grade of 4.35%.

 

Several recent intercepts at Kalayi fall within the reported thickness range
of the Mpama North Main Vein and include multi-metre intervals grades above 3%
tin, with high-grade zones exceeding 5% tin. The continued intersection of
such grades in the deeper drillholes supports the Company's structural
interpretation and reinforces confidence that high-grade tin mineralisation
persists at depth below the maiden MRE.

 

With tin currently trading at approximately US$50,000 per tonne, the delivery
of multi-metre high-grade intercepts is particularly meaningful in the
prevailing pricing environment.

intercepted around 77 metres depth.

 

 

Use of XRF for Initial Results

 

The portable XRF used at Bisie North is a Thermo Scientific Niton(TM) XL3t
model. Readings represent averages of 60 second continuous analysis along 1m
sections of core. The X-ray beam is emitted through an 8mm window and
penetrates several millimetres into the drill core. The metal grades
determined by the portable XRF are indicative only and 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.

 

Investor Call - Thursday 19 February 2026

 

As noted on 10 February 2026, the Company will host an interactive investor
call on Thursday, 19 February 2026 at 12:00 p.m. GMT via its website. The call
will provide further discussion of the recently announced drilling progress at
Kalayi and outline planned work at Mont Agoma.

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

 

"We are highly encouraged by the continued high-grade tin intercepts at depth
at Kalayi, which provides further validation of our structural model.
Delivering multi-metre intervals grading above 3% tin, including zones
exceeding 5%, is a strong technical outcome from this phase of the drilling
campaign.

 

Kalayi lies within the same regional structural corridor as the Mpama North
Mine operated by Alphamin, approximately 8km to the south.  While it remains
early in our evaluation, the widths and grades encountered to date support the
strength of this geological analogy and reinforce our confidence in the system
we are defining.

 

As drilling continues, we expect to further refine our understanding of the
scale and continuity of mineralisation ahead of the anticipated resource
update in the coming months.

 

In parallel, our advanced geological modelling work at Mont Agoma is refining
our next phase of drill targeting, and we expect to provide a further update
on this work shortly. We look forward to discussing our progress announced to
date at both prospects during our investor call on 19 February 2026."
