Strategic Minerals plc (AIM: SML; USOTC: SMCDF) has provided a detailed operational update on its Redmoor Tungsten-Copper-Tin Project in Cornwall, UK, confirming that over 1,068 samples from six drillholes are currently being processed at ALS Laboratories in Ireland. The company has also confirmed that Phase 1 of its Metallurgical Study, to be conducted by Alfred H Knight and incorporating TOMRA ore sorting technology, is scheduled to commence in early December 2026. A partial resource update is targeted before the end of Q1 2027, with the aim of upgrading an eastern portion of the Redmoor Inferred Mineral Resource to Indicated status.

Key Points

  • Strategic Minerals plc (AIM: SML; USOTC: SMCDF) — international mineral exploration and production company
  • 1,068 samples from six Redmoor drillholes currently being processed at ALS Laboratories in Ireland; a further 199 samples from CRD052 scheduled for dispatch
  • Phase 1 Metallurgical Study to begin December 2026 at Alfred H Knight, using 300kg of combined drillhole material and TOMRA ore sorting; six additional metallurgical drillholes totalling 3,880m added to the programme
  • Investors may be watching for the Q1 2027 partial resource update and steady batch results as drilling advances towards 22,500m infill completion

Redmoor Sampling Pipeline: 696 Samples Reported, More Than 1,000 Further Samples in Progress at ALS Laboratories

Cornwall Resources Limited (CRL), Strategic Minerals' wholly owned subsidiary developing the Redmoor project, confirmed that 696 samples have already been analysed and reported by ALS Laboratories, contributing to results from three drillholes on Pad 4. An additional 1,068 samples from six drillholes — CRD044, CRD045, CRD046, CRD048, CRD053 and CRD054 — are currently being processed, spanning three drill sites. CRL has focused initial sampling on Pad 4 to review drill programme progress and assess continuity of mineralisation at Redmoor's easternmost section. Drilling across all three rigs remains active, with Pad 5 fully completed and operations now remobilised to Pad 6.

Alfred H Knight to Lead Phase 1 Metallurgical Study in December 2026 Using TOMRA Ore Sorting and 300kg of Combined Core Material

Two dedicated metallurgical drillholes, CRD053 and CRD054, totalling 1,096.30m, have been drilled, logged and dispatched to ALS Laboratories. Results from these holes, combined with samples from CRD044_D1 and historical drillcore from CRD037, will form the basis for Phase 1 of the Metallurgical Study at Alfred H Knight, commencing in early December 2026. This phase will utilise 300kg of combined material and deploy TOMRA ore sorting technology to refine dense mineral separation, gravity separation and froth flotation phases of the processing circuit, targeting defined recoverabilities for tungsten, copper, tin and silver.

Six Additional Metallurgical Drillholes Totalling 3,880m Prioritised to Accelerate Feasibility Study Pathway at Redmoor

Beyond the existing 22,500m infill drill programme, CRL has scheduled six further metallurgical drillholes totalling 3,880m to support Phases 2 and 3 of the metallurgical testwork programme. The announcement states these holes have been deliberately prioritised to accelerate the metallurgical schedule and ensure timely delivery of a defined processing flowsheet ahead of a future Feasibility Study. Separately, 105 geotechnical drillcore samples from five completed drillholes have been collected for external laboratory testwork under international standards, while 19 drillcore samples have been selected for mineralogical and geochemical analysis within the granitic orebody's mineralised zones.

Q1 2027 Partial Resource Upgrade Targeted for Eastern Redmoor Inferred Resource as Integrated Feasibility Programme Advances

The current drilling and analytical sequencing supports a phase 1 partial resource update scheduled before the end of Q1 2027, targeting an upgrade of an eastern portion of Redmoor's Inferred Mineral Resource to Indicated status. The project's existing JORC (2012) compliant total Inferred Mineral Resource stands at 17.40 million tonnes at 0.65% WO3 equivalent grade, as published on 26 March 2026. The competent person review, conducted by Laurie Hassall of Snowden Optiro, confirmed that exploration results reported in this update do not materially affect the existing Mineral Resource estimate, and that underlying assumptions continue to apply.
