Strategic Minerals Plc Provides Updates On Analytical Testing Of 2025 Drill Core And Project Progress At Redmoor Tungsten-Tin-Copper Project
Strategic Minerals Plc provided updates on analytical testing of 2025 drill core and project progress at its Redmoor Tungsten-Tin-Copper Project, located in Cornwall, UK. 201 additional samples from CRD041 were sent to ALS Laboratories Loughrea, Ireland, as part of CRL's technical review process of the 2025 drilling programme that concluded with the 2026 Redmoor Mineral Resource Estimate Update. These additional results have identified tin-rich mineralised structures up to 1.00 m @ 0.67% Sn from 291.10 m, along with tungsten enriched structures, to the north of the Redmoor deposit and outside the currently modelled resource. These results have contributed to the identification of new tin and tungsten intersections outside of the Redmoor Sheeted Vein System, including: 1.00 m @ 0.67% Sn, 0.20% WO3 and 0.09% Cu (0.48% WO3.Eq) from 291.10 m; 1.95 m @ 0.62% Sn, 0.01% WO3 and 0.04% Cu (0.26% WO3.Eq) from 353.05 m; 0.75 m @ 0.51% Sn, 0.03% WO3 and 0.05% Cu (0.24% WO3.Eq) from 213.00 m; 1.65 m @ 0.45% Sn, 0.02% WO3 and 0.14% Cu (0.22% WO3.Eq) from 263.00 m. Drilling of CRD043 has concluded, with the drillhole successfully intersecting the full extent of the Redmoor SVS and the identification of strongly mineralised vein structures containing wolframite (tungsten), cassiterite (tin) and chalcopyrite (copper) respectively. CRD043 has been logged to date with 291 samples selected and submitted to ALS Laboratories to undergo analysis, with drilling of CRD044 currently underway. Drillhole CRD044 is advancing to schedule and is currently at 455.30 m of a 650.00 m planned drill depth. Historical re-logging and sampling of drill core from the previous 2017-2019 drilling programme continues at pace, with samples from CRD013 and CRD015 identifying additional tin-bearing structures, including: 1.65 m @ 0.38% Sn, 0.01% WO3 and 0.02% Cu (0.17% WO3.Eq) from 202.15 m. Planning permission for the expanded drill programme is well advanced, with all responses to statutory comments complete. Additional drill rigs are standing ready for mobilisation to site upon successful receipt of permissions. Following the publication of the 2026 Redmoor MRE, CRL has completed a review of the resource and new geological model to identify and select additional structures and zones within existing CRL drill core with the potential to contain mineralisation. Results are aimed at confirming extensions of mineralisation, such as the North Tin Zone, identifying further mineralisation, and further improving geological certainty. Additional tin-bearing structures were identified north of the North Tin Zone, with a newly identified structure producing 1.00 m @ 0.67% Sn,0.20%WO3 and 0.09% Cu from 291.10 m, which correlates with a previously identified interval in CRD040 producing 2.51 m @ 0.34% Sn,0.02%WO3 and 0.09% Cu from 286.49 m. This new mineralised structure lies outside previously modelled resources and shows structural continuity between drillholes CRD040 and CRD041. This tin-tungsten rich zone will be considered when future resource infill drillholes are initiated in this area, to test the continuity of the mineralisation and support future assessment of its potential contribution to the project. Highlights from these results include: 1.00 m @ 0.67% Sn, 0.20% WO3 and 0.09% Cu (0.48% WO3.Eq) from 291.10 m in sample CRL007176; 1.95 m @ 0.62% Sn, 0.01% WO3 and 0.04% Cu (0.26% WO3.Eq) from 353.05 m in sample CRL007228; 0.75 m @ 0.51% Sn, 0.03% WO3 and 0.05% Cu (0.24% WO3.Eq) from 213.00 m in sample CRL007115; 1.65 m @ 0.45% Sn, 0.02% WO3 and 0.14% Cu (0.22% WO3.Eq) from 263.00 m in sample CRL007155. Additional sampling of historical drillcore and programme updates: Through the purchase of a new CoreWise rotary diamond blade core saw, CRL has been able to accelerate its sampling of historical drill core following the relogging process, with geological structures containing visible mineralisation sent to ALS Laboratories, Loughrea for analysis. Currently, CRL has 248 samples from drillhole CRD042 awaiting analysis at ALS Loughrea and a batch of 291 samples from CRD043 recently dispatched for analysis. Furthermore, CRL has submitted an additional 59 samples from CRD001, sent on 1 June 2026, for analysis. CRL geologists are currently re-logging drillhole CRD016, drilled during the 2017-18 drilling campaign, with additional intervals already identified and selected for sampling and analysis at ALS Laboratories. CRL, in conjunction with external consultants Snowden Optiro, are currently identifying and selecting drill core samples and planning additional drillholes to support the comprehensive metallurgical testwork that will be used in refining the previously developed mineral processing flowsheet. This programme will support in the confirmation of the most efficient and cost-effective processing route for any ore produced from any potential operation.
