Redmoor - Continuation of High-Grade Tungsten and Identification of High-Grade
Tin Zones
Latest drill results confirm strong WO(3), Sn and Cu mineralisation;
mineralised continuity within the Redmoor SVS high-grade zones; & validity
of historical results
Strategic Minerals plc (AIM: SML; USOTC: SMCDF), an international mineral
exploration and production company, is delighted to announce that its wholly
owned subsidiary, Cornwall Resources Limited ("CRL"), has received assay
results from drillhole CRD036 - the first from Pad 2 within the Redmoor
Tungsten-Tin-Copper Project ("Redmoor") in southeast Cornwall - including
further confirmation high-grades of tungsten and tin within the Sheeted Vein
System ("SVS").
CRD036 was aimed at twinning*(1) historical drillholes and identifying
mineralised continuity at shallower depths and within a hole designed to
intersect a higher-grade, tin-dominant portion of the high-grade tungsten
deposit.
Highlights:
Tin downhole intersections
· High-grade intersections from new tin-dominant zones include:
o 0.50m @ 1.26% Sn, 0.02% Cu & 0.02% WO(3) (1.06% WO(3).Eq) from 314.82
m
o 0.95m @ 1.18% Sn, 0.01% Cu & 0.02% WO(3) (0.99% WO(3).Eq) from 336.05
m
o 0.70m @ 1.92% Sn, 1.09% Cu & 0.37% WO(3) (2.23% WO(3).Eq) from 383.40
m
Tungsten downhole intersections
· High-grade tungsten intersections include:
o 4.50m @ 0.47% WO(3), 0.14% Sn & 0.24% Cu (0.65% WO(3).Eq) from 372.50
m
o 1.00m @ 1.00% WO(3), 0.02% Sn & 0.58% Cu (1.17% WO(3).Eq) from 406.00
m
o 0.70m @ 0.86% WO(3), 0.07% Sn & 0.82% Cu (1.13% WO(3).Eq) from 432.00
m
· Further high-grade sample intervals, inside broad intersections,
including:
o 18.50 m @ 0.14% WO(3), 0.20% Sn & 0.25% Cu (0.37% WO(3.) Eq) from
371.50 m, (see Figure 1) containing:
§ 0.80m @ 1.02% WO(3), 0.09% Sn & 0.45% Cu (1.21% WO(3).Eq) from 372.50 m
§ 0.54m @ 1.85% WO(3), 0.28% Sn & 0.22% Cu (2.13% WO(3).Eq) from 374.51 m
Copper downhole intersections
· High-grade intersections include:
o 1.65m @ 1.09% Cu, 0.05% Sn & 0.23% WO(3) (0.56% WO(3).Eq) from 401.90
m
o 1.00m @ 1.03% Cu, 0.04% Sn & 0.01% WO(3) (0.32% WO(3).Eq) from 415.00
m
Silver*(2)
· CRD036, like previous drill holes, reports elevated silver values in
relation to mineralisation within zones that are copper-rich, demonstrated by:
o 5.10m @ 0.66% Cu, 0.03% Sn & 0.34% WO(3), and 15.5g/t Ag from 401.90
m, including 1.65 m @ 33.9 g/t Ag from 401.90 m
Twinning Results and Model Updates
Positive results from the drillhole twinning, and new insights into Redmoor
deposit, including:
· Twinning results between CRD036 and RM80_05B & 05C (1980s
drillholes) highlight continuity of structures and reproducibility of
historical results. This provides confidence for the use of the 1980s
drillhole data in the deposit model and Mineral Resource estimate ("MRE")
thereby reducing future prefeasibility drilling requirements.
· Drillhole results have returned multiple zones of high-grade tin and
copper intersections, supporting the presence and continuity of tin-copper
lode structures within the existing Redmoor Mineral Resource, which will be
further studied as part of the MRE update - these will be further detailed in
a forthcoming update on the new Redmoor deposit model.
Figure 1: Box photos with sample intervals (Yellow Arrows), highlighting an
18.50m intersection including highlighted high-grade tungsten and tin
intervals. All samples are listed in tungsten trioxide equivalent (WO(3).Eq).
Dennis Rowland, CRL Managing Director, said:
"The assay results report a trifecta of high-grade tungsten, tin and copper
intersections for the first time from the 2025 programme within a tin-dominant
zone of the deposit, along with analytical results for silver - which are
being further investigated as part of ongoing metallurgical studies.
Drillhole results continue to return multiple zones of high-grade tin and
copper intersections, supporting the presence and continuity of tin-copper
lode structures within the existing Redmoor Mineral Resource, which will be
further modelled. This drillhole was designed as a twin of holes drilled by
Southwest Minerals (SWM) in the 1980s and provides further confidence in these
historical datasets.
Following the receipt of these results, an update on the new Redmoor deposit
model and the outcome of the twinning programme is expected shortly."
Mark Burnett, Strategic Minerals Executive Director, said:
"Positive results such as these further highlight Redmoor's position as the
highest-grade, undeveloped tungsten resource in Europe, and amongst the
highest grade globally.
This is a crucial time for critical minerals projects, given significant
global supply chain shifts alongside export controls resulting in a marked
increase in metal prices and interest in the sector. The Board are focussed on
the acceleration of the Redmoor project through an updated mineral resource
and planned prefeasibility study ("PFS") thereafter. This will be supported by
the recently completed fundraise for a significant infill drilling programme,
designed to shorten drillhole spacing within the resource, as the major
requirement for converting the deposit to an Indicated resource classification
ahead of the planned PFS."

Figure 2: Plan (top-down) view of the previously modelled high-grade domains
(gold) used in the 2019 Redmoor MRE, showing CRD036 (in red) and other CRL and
SWM drillhole traces (black). CRD036 is an infill hole aimed at testing
short-spaced continuity of structure and grade.
Drill hole CRD036 (see Table 1 & Figure 2) was intentionally drilled to
twin historical drilling results and confirm the presence of tin and
copper-rich structures historically drilled (drill hole RM80_05B and 05C),
along with identifying the higher-grade tin-rich section of the resource and
shallower extent of the SVS system. The outcomes of the twinning programme
will be further detailed shortly alongside updates to the deposit model, ahead
of the MRE update expected Q1 2026.
Laboratory assay results for drillhole CRD036 have returned further positive
results from the current drilling programme, containing high-grade results,
with tungsten (WO(3)) grades reaching 1.85%, copper (Cu) grades reaching
1.09%, and very-high-grade tin (Sn) grades reaching 1.92%, from a zone of the
deposit known to be enriched in tin concentrations, coupled with silver (Ag)
grades of up to 33.9 g/t correlated with copper mineralisation.

including sample depths, thickness, metal content, and tungsten equivalent

Note*(1) Twinned drillholes refer to new CRL drillholes which are aimed to
intersect SVS mineralisation in close proximity to previous historical
drilling undertaken by South West Minerals in 1978-1982, in order to verify
the robustness of the historical drilling data, as well as test the
continuity/reproducibility of grade and structure across the spacing between
the drillholes.
