Discovery of New Tin Zone at Mont Agoma

 

Rome Resources Plc (AIM: RMR), the DRC-focused tin and base metals explorer,
is pleased to announce the discovery of a new tin zone on the eastern flank of
the Mont Agoma prospect at its flagship Bisie North project in North Kivu
Province, eastern DRC.

Highlights

·    New tin zone intersected in hole MADD030: 40m interval in shallow
weathered sequence.

·    XRF on-site confirms significant tin mineralisation; assays pending.

·    Sits outside existing soil anomaly and drilled area, suggesting a
possible new system or fault-generated repetition.

·    Potential for significant upside expansion along the eastern flank
of Mont Agoma.

·    Three rigs active; four holes drilled (737m) since 13 May, all
encountering broad visual mineralisation.

·    Maiden Resource Estimate (MRE) work underway.

 

Further details

Drill hole MADD030, located northeast of known mineralisation, intercepted a
40m wide tin-bearing zone at shallow depth.  Although visual identification
of cassiterite is limited in the weathered rock, initial Niton XRF readings
confirms elevated tin levels, suggesting strong potential. Grades of tin
mineralisation will be provided once laboratory results are reported.

Importantly, the mineralised intercept at MADD030 lies well outside both the
current mineralised footprint and the tin-in-soil geochemical anomaly (Figure
1), potentially representing either a new tin system zone or a fault
repetition of known mineralisation (Figure 2).

The newly drilled zone further suggests that there could be significant
additional tin resource along the eastern flank of Mont Agoma.

Following the deepening of hole MADD030 (now MADD030A) to better understand
the structural model, two follow-up drill holes will test the extension of
this newly identified zone to the northwest.

To date, four holes totalling 737m have been completed since 13 May 2025 with
three rigs currently drilling. All four holes have intersected visual tin,
copper and zinc mineralisation and confirmed with the on-site Niton XRF
analyser.

Broader zones of mineralisation are highlighted below, with no inference as to
grade:

·    MADD023: 50m Sn (38 - 88m), 8m Cu (105 - 113m), 31m Zn (57 - 88m)

·    MADD025: 54m Sn (123 - 177m), 6m Cu (120 - 126m), 80m Zn (106 - 186m)

·    MADD027:  57m Sn (61-118m), 71m Cu (67-138m), 57m Zn (67-124m)

Samples will be sent to ALS Global in South Africa with assay results expected
before 31 July 2025.

 

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

 

"To date all the Mont Agoma drilling has focused on the main ridge where the
geochemical anomaly is strongest. These initial indications from MADD030 open
up the exciting scenario where tin mineralisation is present beyond the limits
of our known footprint, potentially opening up the whole of the eastern flank
of Mont Agoma. This is exactly the kind of upside we hoped to unlock with this
new phase of drilling.

 

With three rigs turning, work in relation to our maiden mineral resource
estimate underway and work due to start soon on the metallurgy of the deposit,
Rome is building serious momentum on both the exploration and development
fronts. We will continue sharing further updates in relation to drilling
progress as well as assay results as they become available."
