Strategic Minerals* (SML LN) 1.68p, Mkt Cap £40m – Redmoor drilling nears completion as metallurgical testing shows >90% recoveries for tungsten, tin & copper • As its current drilling campaign at the Redmoor project in Cornwall nears completion, Strategic Minerals has issued a progress report. • The company confirms that “To date, 4,392.77 m of drill core has been produced, logged and reviewed for sampling” and that after completing a total of 6 holes (3213.1m), including the latest, CRD-040 completed at a depth of 424.20m, on 8th November, “Rig 1 … will demobilise today”. • The remaining rig is currently drilling the final hole of the campaign, CRD-041 “which is advancing well”. • The company highlights that hole CRD-039, in common with hole CRD-037, “intersected a key portion of Redmoor's JORC (2012) Exploration Target, designed to test the continuity of the Sheeted Vein System ("SVS") and evaluate areas with potential to contribute to future resource growth within the zone integral to the mining model in Redmoor's 2020 Scoping Study”. • Pending receipt of assay results from the latest drilling, today’s announcement includes photographs of mineralised drill core which illustrate coarse grained wolframite (tungsten) mineralisation, cassiterite (tin) and the presence of “massive sulphides dominated by chalcopyrite (copper) in drill core”. • We consider the presence of coarse-grained mineralisation as positive as it offers the potential for relatively coarse grinding to liberate economic minerals which should help to contain power costs required for future mineral processing. • Exploration Manager, Rowan Thorne, described the objectives of the drilling campaign as “including twin drilling of 1980s drill holes, validation of short-spaced continuity of grade and structure within the SVS, and infill drilling of a key section of the Redmoor JORC Exploration Target”. • He said that … “subject to analytical testwork confirmation … we have met these goals, further derisking Redmoor and providing key information for the MRE update and future infill drilling campaigns”. • In today’s announcement, Strategic Minerals also describes progress with metallurgical test work “for full flowsheet design … for tungsten, tin, and copper recovery … [which] … is progressing ahead of schedule”. • The testing uses “representative SVS material from the project” including encouraging tests on crushing and grindability which are expected to deliver improved results “when evaluating pre-concentrated material”. • The metallurgical work also included “a comprehensive heavy liquid separation ("HLS") programme on all +1mm 10 mm material” to determine the optimal specific gravity for “mass and metal recoveries”. • Overall, the metallurgical test results so far are described as “encouraging, with mass recovery to flotation feed of approximately 43.9%, and stage metal recoveries of 94.3% t
