Redmoor - Positive Drill Results from Underexplored Western Portion of SVS
Strategic Minerals plc (AIM: SML; USOTC: SMCDF), an international mineral exploration and production company, announces that its wholly owned subsidiary, Cornwall Resources Limited ("CRL"), has received assay results from drillhole CRD041 from the Redmoor Tungsten-Tin-Copper Project ("Redmoor") in southeast Cornwall.
Results confirm the continuity of the Sheeted Vein System ("SVS") containing high-grade tungsten- and tin-dominant mineralisation, with copper and silver mineralisation also present, in the westward extent of the 2019 Redmoor JORC (2012) Redmoor Mineral Resource. Results also confirm the presence of additional non-SVS mineralised zones to the north of the SVS.
The western portion of the Redmoor deposit, more distal from the granite, forms a zone containing a higher proportion of tin-dominant, rather than tungsten-dominant, mineralisation with higher grades of tin. By comparison, the eastern and central portions of the deposit contain a higher proportion of tungsten-dominant mineralisation with higher tungsten grades. The polymetallic composition of the deposit adds value as shown by the WO3.eq*1 calculations.
SVS Downhole Composite Intersections Highlights
Multiple higher-grade intervals within high-grade tungsten- or high-grade tin-dominant structures including copper were identified with results, including:
o 0.94% WO3 and 0.46% Cu over 0.95m from 507.00 m*2
o 1.57% Sn and 1.55% Cu over 2.18m from 575.95 m
o 2.54% Sn and 3.38% Cu over 0.88m from 580.62 m
High-grade tungsten equivalent ("WO3.eq") intersections from SVS-style and lode-style structures containing tungsten, tin and copper mineralisation within the SVS in the western portion of the resource (see Figure 1 & 2), which is tin-dominant:
· 9.18m @ 0.52% Sn, 0.17% Cu & 0.06% WO3 (0.53% WO3.Eq) from 528.92 m, with
o 3.40m @ 1.00% Sn, 0.15% Cu & 0.02% WO3 (0.89% WO3.Eq) from 531.25 m
o 1.35m @ 0.70% Sn, 0.31% Cu & 0.19% WO3 (0.85% WO3.Eq) from 536.75 m
· 6.85m @ 0.28% Sn, 0.30% Cu & 0.11% WO3 (0.42% WO3.Eq) from 553.70 m, with
o 1.30m @ 0.11% Sn, 0.22% Cu & 0.45% WO3 (0.60% WO3.Eq) from 553.70 m
o 1.00m @ 0.86% Sn, 0.47% Cu & 0.18% WO3 (1.01% WO3.Eq) from 556.00 m
· 8.10m @ 0.50% Sn, 0.65% Cu & 0.25% WO3 (0.84% WO3.Eq) from 571.00 m, with
o 1.45m @ 0.26% Sn, 0.80% Cu & 0.86% WO3 (1.29% WO3.Eq) from 571.00 m
o 2.18m @ 1.57% Sn, 1.55% Cu & 0.22% WO3 (1.93% WO3.Eq) from 575.95 m
· 4.68m @ 0.66% Sn, 0.97% Cu & 0.03% WO3 (0.83% WO3.Eq) from 580.62 m, with
o 0.88m @ 2.54% Sn, 3.38% Cu & 0.01% WO3 (3.00% WO3.Eq) from 580.62 m
o 1.17m @ 0.50% Sn, 0.75% Cu & 0.01% WO3 (0.62% WO3.Eq) from 584.13 m
Non-SVS Downhole Intersections
· CRD041 intersected a new zone of non-SVS mineralisation with visible cassiterite (see RNS: 01 December 2025) (see Figure 3). With a sample intersect of 4.00m @ 0.25% Sn, 0.01% Cu from 476.00m, including:
o 2.00m @ 0.40% Sn, 0.02% Cu & 0.00 WO3 (0.34% WO3.Eq) from 478.00 m
· Further information on this newly identified, tin-dominant, non-SVS zone will follow shortly, alongside modelling outputs which are expected to define this zone
· CRD041 also intersected additional zones of mineralisation outside of the current resource model, including two intervals containing tungsten, tin and copper with silver*1 intersections, returning grades of:
o 0.65m @ 0.22% WO3, 0.24% Sn & 3.19% Cu (1.28% WO3.Eq) also containing 75.8g/t Ag from 191.85 m,
o 4.00m @ 0.17% WO3, 0.11% Sn & 0.32% Cu (0.34% WO3.Eq) also containing 19.1g/t Ag*3 from 197.00 m, and

Dennis Rowland, CRL Managing Director, said:
"Drillhole CRD041 intersected the Redmoor SVS, in the western extent of the current Mineral Resource, within an area of the deposit where the mineral zonation has a higher proportion of tin-dominant high-grade zones. The drillhole results contain multiple intersections of tungsten- and tin-dominant mineralised zones from within the SVS, with these zones also classified as high-grade on a tungsten equivalent basis.
Additional intersections within the non-SVS section of the drillhole indicate the potential for further zones of mineralisation outside of the current MRE which may, subject to further delineation, estimation and assessment of Reasonable Prospects for Eventual Economic Extraction ("RPEEE"), support future resource definition."
Mark Burnett, Strategic Minerals Executive Director, said:
"The 2025 drill programme at Redmoor has shown the high-grade nature of the SVS deposit, as well as its zonation. With the structural shifts in global metal prices, especially for tungsten and tin, Redmoor's multicommodity composition has the potential to provide significant economic benefits.
The Company is on schedule to complete its Shared Prosperity Fund match grant-funded activities by the end of Q1 2026, including the new Mineral Resource Estimate and economics updates, which we expect will further highlight the potential of Redmoor as one of the highest grade, undeveloped, tungsten resources in Europe."
Detail of analytical results from CRD041
CRD041 (see Table 1, and Figure 1, 2 & 3) was the final drillhole from Pad 3 at Redmoor between October and December 2025. CRD039, the second last drillhole, has been delayed at the laboratory due to additional QAQC checks, but is expected to be reported shortly.
