Redmoor - Ultra-High-Grade Drill Results
Results from CRD039 include ultra-high-grade tungsten at 18.96% WO3
Tungsten equivalent grade of 22.09% WO3.Eq over 0.6 m within the high-priority section of the previously untested Exploration Target
This is the highest-grade WO3.Eq single sample interval ever drilled at Redmoor
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 CRD039, including ultra-high-grade intersections and long intersections of high-grade mineralisation from the Redmoor Tungsten-Tin-Copper Project ("Redmoor") in southeast Cornwall.
Highlights
· CRD039 has returned an ultra-high-grade*1 tungsten, tin, and copper sample intercept, containing:
o 0.60m @ 18.96% WO3, 2.76% Sn & 3.19% Cu for a tungsten equivalent grade of:
§ 22.09% WO3.Eq from 563.13 m.
o Second highest-grade tungsten sample interval*1 from Redmoor recorded by CRL, and the single highest-grade tungsten equivalent*2 sample interval ("WO3.Eq") recorded to date.
· High-grade tin intersects, containing high-grade tungsten and copper, including:
o 1.52m @ 7.45% Sn, 2.09% WO3 & 5.21% Cu for a tungsten equivalent grade of:
§ (9.60% WO3.Eq) from 528.78 m.
o The highest-grade tin sample intersection*1 drilled at Redmoor
· High-grade silver*3 associated with copper mineralisation within the Sheeted Vein System ("SVS"):
o 1.52m @ 72.3 g/t Ag, 5.21% Cu, 7.45% Sn and 2.09% WO3 from 528.78m
o 1.08m @ 82.9 g/t Ag, 5.13% Cu, 2.76% Sn and 0.05% WO3 from 538.92m
o 0.64m @ 74.7 g/t Ag, 5.41% Cu, 5.17% Sn and 0.19% WO3 from 563.73m
· CRD039 intersected multiple high-grade zones of significant width, including:
o 12.88m @ 0.37% WO3, 0.54% Sn & 1.03% Cu (1.09% WO3.Eq) from 535.68 m
o 6.64m @ 1.74% WO3, 0.87% Sn & 1.20% Cu (2.78% WO3.Eq) from 562.36 m
· Further identification of SVS and lode-style mineralisation within the high priority section (see Figures 1, 2 & 3) of the 2019 Redmoor JORC (2012) Exploration Target (the "Exploration Target"), and additional mineralisation outside the Redmoor SVS, supporting:
o The potential to test and convert additional portions of the Exploration Target from the 2019 Mineral Resource Estimate ("MRE") to Mineral Resources, subject to drilling, estimation, and demonstration of reasonable prospects for eventual economic extraction ("RPEEE"); and
o The continuity of mineralisation within the newly identified 'North Tin Zone'.
Downhole Intersections Highlights
High-grade tungsten, tin, and copper from SVS-style mineralisation:
· 4.59m @ 0.42% WO3, 0.35% Sn & 0.38% Cu (0.84% WO3.Eq) from 497.41 m, containing
o 0.75m @ 2.33% WO3, 1.70% Sn & 2.03% Cu (4.27% WO3.Eq) from 499.09 m
· 3.00m @ 0.47% WO3, 0.52% Sn & 1.32% Cu (1.25% WO3.Eq) from 505.00 m, containing

· 1.00m @ 1.09% WO3, 0.20% Sn & 0.73% Cu (1.45% WO3.Eq) from 558.28 m
· 1.24m @ 9.28% WO3, 4.00% Sn & 4.34% Cu (13.73% WO3.Eq) from 563.13 m, containing
o 0.60m @ 18.96% WO3, 2.76% Sn & 3.19% Cu (22.09% WO3.Eq) from 563.13 m
Dennis Rowland, CRL Managing Director, said:
"These results further demonstrate the quality of mineralisation at Redmoor and its position as one of the highest-grade, undeveloped tungsten projects in Europe*4.
CRD039 is the final drillhole to be reported from the nine-hole, 5,000 m drill programme, completed between June and December 2025. CDR039 intersected multiple ultra-high-grade intersections of mineralisation within the SVS, including the single highest-grade tungsten equivalent sample interval recorded by CRL to date, alongside multiple thick zones of high-grade mineralisation containing tungsten, tin and copper.
This drillhole further confirms the continuity of SVS mineralised structures within the high-priority section of the Exploration Target, which may support conversion to resources subject to RPEEE analysis in the upcoming Mineral Resource Estimate update.
All drillhole data from the 2025 drilling programme has now been reported and has been incorporated into the final datasets to be used for the forthcoming MRE update."
Mark Burnett, Strategic Minerals Executive Director, said:
"Throughout the past 12 months, whilst the Shared Prosperity Fund matched grant-funded project has been underway, metal prices for tungsten, tin, and copper have shown significant upwards momentum. With tungsten prices approaching $2,000 mtu APT ($200,000 ton APT)1 following an evident structural shift in supply chains and markets, the Company views Redmoor as a strategic asset and is intent on advancing the project expeditiously.
With only the results from the metallurgical testworks outstanding, which the Company expects to further highlight the strengths of Redmoor's polymetallic SVS deposit, we are on schedule to complete the MRE and economic updates for the project by the end of Q1 2026 and move swiftly into the next phase of development."
