Strategic Minerals has drilled more than 7,500 metres at its Redmoor tungsten, tin and copper project in Cornwall, Britain, completing 13 holes in a programme intended to support a new resource estimate and, eventually, a feasibility study.
The company reported on 6 November that 11 of the completed holes were among 42 planned resource infill holes, while two were for metallurgical studies. Redmoor is being advanced by Strategic Minerals’ wholly owned subsidiary Cornwall Resources. The company said the campaign remained on schedule and within budget.
Drilling and sample results
Drilling identified previously unmodelled mineralisation in granite beneath Redmoor’s sheeted-vein system. Hole CRD054 encountered visually identifiable wolframite and chalcopyrite beneath zones included in the existing geological model. Other holes found cassiterite-bearing structures north of the modelled resource and the North Tin Zone.
The observations are from drill core and are not assay-confirmed grades. Strategic Minerals had submitted 728 samples from four holes for laboratory analysis, and another 155 samples from CRD054 were being delivered. Further sampling and assay results will determine whether the apparent extensions can be included in an updated resource.
Resource and development work
Redmoor’s existing inferred mineral resource is roughly 17.4 million tonnes, a classification that carries geological uncertainty. The infill programme is intended to improve confidence in known mineralisation and support a new estimate. Visible minerals in additional holes may broaden the geological model but do not establish extra mineable tonnes or justify a construction decision.
Metallurgical and geotechnical work is intended to provide data for mine design, recovery assumptions and future capital-cost estimates. Cornwall has a history of tin mining and renewed interest in tungsten resources. Tungsten is used in cutting tools, industrial equipment and defence applications.
If Redmoor advances beyond exploration, domestic processing economics, permitting, infrastructure and access to construction finance will matter alongside mineral grades. Verified assays, an updated resource and metallurgical results are the next valuation milestones.
