Mont Agoma delivers Broad Copper and Zinc Intersections as Drilling Resumes in
the DRC
Rome Resources Plc (AIM: RMR), the DRC-focused tin and base metals explorer,
is pleased to announce assay results from drill holes MADD024 and MADD026 at
its Mont Agoma prospect, which continues to return large intercepts of
near-surface and high-grade polymetallic mineralisation (see Figure 1 below).
These assay results confirm the continuation of broad copper and zinc
mineralisation over a 176m mineralised envelope in hole MADD024 and supports
the Company's exploration model of a polymetallic system transitioning into
deeper tin mineralisation.
Assay Highlights
· MADD024:
o 14.8m @ 0.67% Cu from 59.1m, incl. 0.7m @ 2.32% Cu from 62.4m
o 13.4m @ 1.26% Cu from 109m, incl. 2.83m @ 2.13% Cu from 119.6m
o 14.5m @ 1.57% Cu from 174m, including 5.13m @ 3.00% Cu from 180.4m
o Tin visible over a 28m interval, reinforcing depth-related zonation
· MADD026:
o 54m @ 3.41% Zn from 113m, incl. 21m @ 5.96% Zn from 126m
o 20m @ 1.23% Cu from 193m, incl. 5.10m @ 3.12% Cu from 193.9m
o Tin visible over a 15m interval
· System scale: Copper and zinc confirmed across a 500m strike and
>200m width
· Next phase: Deeper tin targets now being drilled in short 3,000m
campaign
Drilling continues to support the Company's zonation model with shallower
copper and zinc transitioning into tin at depth - that the Board considers
akin to well-known, established tin projects like San Rafael in Peru and South
Crofty in the UK, both of which started as copper mines, passed through a
transition zone of tin and copper until both were ultimately only mining tin.
Notably, both holes reported visible cassiterite in the core, with
mineralisation widening at depth and tin appearing near the base of the copper
zones.
Ongoing Work and Exploration Focus:
· Polymetallic footprint continues to grow: Drilling to date has
defined polymetallic mineralisation over 500m of strike length and a width of
more than 200m, mineralisation remains open at depth and along strike. The
system remains open at depth and along strike, with step-out drilling in
progress.
.
· Copper mineralisation confirmed in broad zone: Hole MADD024 returned
mineralisation within a broad 176m mineralised envelope, including up to 14.5m
@ 1.57% Cu from 174m (including 5.13m @ 3.00% Cu from 180.4m). MADD026
reported a best intercept of 20m at 1.23% Cu from 193m including 5.10m @ 3.12%
Cu from 193.9m.
· Tin zones strengthening at depth: Cassiterite observed in both hole
MADD024 (28m interval) and hole MADD026 (15m), consistent with the zonation
model. Tin mineralisation is typically hosted within three sub-parallel
structures that widen with depth, combining to 25-40m in thickness.
· Best tin grades to date in southeast: Hole MADD009, drilled in the
southeast, returned 6.65m @ 0.53% Sn from 45.35m, including 2m @ 1.33%
Sn-underscoring southeast and deeper drilling as high-priority targets.
· Metallurgical studies underway: Rome has appointed a specialist
metallurgist to advance mineralogical, metallurgical and processing studies -
focused on economic beneficiation of tin, copper, zinc and silver from the
Mont Agoma and Kalayi systems.
· Resource estimates pending: Maiden inferred mineral resource
estimates for tin, copper and zinc at Mont Agoma - and tin at Kalayi - are in
progress, with publication expected in the near term.
· 3,000m drilling programme underway: Three diamond core drill rigs are
expected to complete the programme at Mont Agoma in the second half 2025 as
part of a short 3,000m campaign focused on deeper tin targets and step-out
drilling to expand the polymetallic footprint.
Paul Barrett, Chief Executive Officer of Rome Resources Plc, commented:
"The exploration at Mont Agoma continues with the recent resumption of
drilling. A number of key tin targets are planned to be drilled, which will
allow us to fine tune the geological model and improve our understanding of
how the three key commodities - copper, zinc, and tin - are distributed within
the mineralised system. The results to date are highly encouraging, confirming
consistent copper and zinc near surface with tin strengthening at depth -
exactly the zonation profile we anticipated.
"This short 3,000 metre campaign is focused on targeting deeper tin
mineralisation, and regular updates are anticipated in the coming months as
results are received, along with the Company's inferred mineral resource
estimate for both Mont Agoma and the nearby Kalayi tin prospect. These steps
mark important progress in demonstrating the scale and value of this emerging
polymetallic system."
Mineralisation at Mont Agoma:
Results from the exploration drilling at Mont Agoma have reinforced the model
of a shallow, predominantly copper and zinc mineralisation system passing at
depth into a tin zone. The Figure 1 below illustrates these findings as
follows:
· The displayed contours are of 'tin potential', being an indicator of
tin richness - the product of average grades above 0.1% and zonal thickness.
· The results to date indicate a strong increase in tin potential in
the deeper parts of the mineralised zone
· Mineralisation plunges in broad terms to the northwest, bringing the
tin zone shallower in the southeast
· Also shown are the planned hole penetrations targeting principally
the deeper tin for the current drilling campaign
Figure 1
There is, in addition to the deeper tin potential, very significant copper and
zinc mineralisation already found in the shallower drill holes. This base
metal occurrence is considered important for two reasons - it represents the
overburden that will require stripping during early-stage mining operations
and it provides a strong opportunity for incremental resource value.
The current drill programme is planned primarily to test the grade and width
of tin mineralisation at pierce points shown on the long section at much
deeper levels than that has been drilled to date. A single drill hole has
additionally been planned to test the continuation of tin mineralisation to
the south of a possible fault. Provision has also been made for additional
drill holes once the tin zone has been located, taking into account that the
best tin intercepts were located in the southern area drilled to date.
The Board considers that all results to date support the model for this style
of mineralisation being analogous to that evidenced at San Rafael in Peru and
South Crofty in the UK. Indications are that Rome's drilling is within the
transition zone in the southern portion of the drilled area where grades have
increased with a marked decrease in copper mineralisation.
MADD024 and MADD026 Results
Results are considered to further support a north plunging mineralised system
where best tin grades were reported in the southernmost drill holes, while
MADD024 and MADD026 over the northern portion reported lesser grades - 27.8m
at 0.13% Sn from 157,2m (MADD024) and 9.5m at 0.12% Sn from 174m and 5.5m at
0.29% Sn from 193m (MADD026).
Copper mineralisation was identified within a number of zones within a broader
176m mineralised envelope in MADD024 which included up to 14.5m at 1.57% Cu
from 174m (including 5.13m at 3.00% Cu from 180.4m) while MADD026 reported a
best intercept of 20m at 1.23% Cu from 193m including 5.10m @ 3.12% Cu from
193.9m. Both holes were clearly drilled within the copper zone although
distinct bands of cassiterite mineralisation were visible in the core which
was mineralised over an interval of 28m in MADD024 and 15m in MADD026.
Copper mineralisation has been identified over significant widths in the
northern area of drilling at Mont Agoma where MADD018 reported copper
mineralisation within a broader 148m envelope and is supported by a copper in
soil anomaly which continues for a further c. 1,000m to the northwest. Similar
to the tin mineralisation, copper mineralisation plunges to the northwest and
pinches out before the last line of drilling in the south. This further
highlights the potential for high grade tin at even deeper levels in the
northern portion which included MADD024 and MADD026.
Zinc was intersected in both MADD024 and MADD026 with a best intercept of 54m
at 3.41% Zn from 113m including 21m at 5.96% Zn from 126m in MADD026. Both
drill holes were stopped before reaching the continuation of the broader c100m
wide zinc zone intersected in MADD001 and MADD002.
All tin, copper, zinc and silver mineralised intercepts are summarised in
Table 1.
