RNS Number : 6939Z  Rome Resources PLC  09 April 2026

9 April 2026

 

 

Rome Resources plc

("Rome Resources", the "Company")

 

 

 

Drilling programme completed

 

Kalayi drilling completed; strong tin results support resource update

 

 

Rome Resources plc (AIM: RMR), the DRC-focused tin and copper explorer, is
pleased to provide an update on its drilling operations at the 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.

 

Drilling operations for the current drilling campaign completed on 4 April
2026, having been active since December 2025.  The Kalayi prospect
represented the bulk of the total metres drilled, being 91%, where the board
of directors of Rome Resources (the "Board") believe the presence of near
surface high-grade tin mineralisation exists and the potential for continued
mineralisation at depth.

 

The highlights of the drilling campaign are set out below. The Company now
looks forward to receiving the formal assays for the tin intercepts
encountered. These results will in turn be incorporated into the subsurface
model. It is also expected that an updated Mineral Resource Estimate, which
could deliver a meaningful uplift, will be announced in due course.

 

Highlights

 

·    The Board believes that drilling confirms the presence of high-grade
tin mineralisation which continues at depth and across multiple holes,
supporting the Company's structural model

·    Widest and strongest intercepts to date delivered during the current
drilling campaign

·    Clear progression in grade and width of mineralisation versus
previous campaigns

·    17 holes drilled for 3,050m, with Kalayi representing the majority of
metres

·    Assays pending, to feed into updated Mineral Resource Estimate

·    Updated MRE expected in the coming weeks

 

Kalayi Drilling Programme

 

Drilling operations for the recent drilling campaign were completed on 4 April
2026 following the drilling of 17 holes for a total of 3,050m.  The Kalayi
prospect represented the bulk of the total metres drilled, being 91%,
targeting what the Board believes to be the presence of near-surface
high-grade tin mineralisation and the potential for its continuation at depth.
Portable XRF results from the programme continue to support the Company's
structural model for the deposit, with the presence of high-grade tin
mineralisation encountered across multiple holes.

 

The Board now looks forward to receiving formal laboratory assays for the tin
intercepts encountered, and these will be incorporated into the subsurface
model and are expected to inform an updated Mineral Resource Estimate.

 

Drilling results update

 

Highlights of the recent drilling campaign include multiple highly encouraging
tin intercepts which have been provisionally assessed using a handheld XRF
device.

 

Figure 1 shows a semi-quantitative comparative overview of the results from
the current and previous campaigns.  To demonstrate the positive progression
in overall tin richness of the various intercepts as the programme has
evolved, intercept richness is presented as the product of intercept width and
tin percentage (using existing assays for the previous campaign and XRF
readings for the current campaign).

 

On this basis, the top five intercepts from the recent drilling campaign
exceed the maximum richness recorded in any previous campaigns intercepts and
are additionally shown in Figure 2.

 

It should be noted that this comparison is based on a combination of
historical assay data and current XRF readings and is therefore indicative
only.  However, for wider intercepts (such as those exceeding 10m), the
impact of averaging is much reduced.

assays)

Results from the current campaign represent the strongest set of intercepts
recorded at Kalayi to date.

 

 

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

 

"The tin intercepts encountered in this recent drilling campaign underscore
Kalayi's potential as an extensive high grade tin deposit situated only 8km
from a mine producing over 7% of the world's tin.

 

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."

 

 

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, although
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.
For critical core intervals, up to four passes are made with the XRF on lines
along the core at 90 degrees separation around the core diameter and averaged
to increase the confidence in the results.
