Zeus Note 5th March - Redmoor - last drill hole assay – “Ultra” high-grade5 Mar 2026 07:40
Redmoor - last drill hole assay – “Ultra” high-grade Strategic Minerals announces its final assay results today for the last hole of the 9 drilled in 2025 at its Redmoor tungsten-tin-copper (WO3-Sn-Cu) project in Cornwall. It announces “Ultra” high-grade mineralisation. While this has no proper geological definition it is a great adjective for grades of 18.96% WO3 (2.76% Sn and 3.19% Cu for 22.09% WO3 Eq*) over 0.6m1 in a quartz vein in the SVS (Overall this lies in a zone of 6.64m1 grading 1.74%WO3, 1.20%Sn, 0.87%Cu - 2.78% WO3 Eq*). This is not the only high-grade intersection as there are also zones of high grade tin and copper e.g.: 1.52m1 of 7.45% Sn and 5.21% Cu; and 1.08m1 of 5.13%Cu, 2.09% Sn, 0.05% WO3 and 83g/t silver). These are high by any standards applied. Importantly the drill hole also intersects a zone of “untested” mineralisation and will therefore be additive to any tonnage increase in the resource. Today’s news is a marvellous end to a very encouraging drilling programme. We maintain our 4.8p per share fair value and look forward to the updated MRE with keen interest. Let’s not dwell on the “ultra” high-grades – these are exceptional and explained above in the opening paragraph. Instead let’s see what the 2025 drilling programme has revealed: Strong, repeatable intersections and grades of tungsten, tin, and copper (and silver). Good geological interpretation of the SVS (it’s where they expect it to be) Strategic Minerals understands the geology and controls on mineralisation and there is recognition of a new “North Tin Zone” which could form a separate orebody within the Redmoor vein complex. All this exploration is set against a background of a tungsten price that has taken off due to Chinese control of this critical metal up ~500% in less than a year; a tin price which is $20,000/t over our long-term price; record high copper prices; and a silver price which is catching up to a normalised gold:silver ratio. High copper usually leads to high silver. In our view this is silver associated with the chalcopyrite phase of mineralisation – in which case we view it as recoverable and will likely to be payable in the copper concentrate and form a valuable by-product credit. Drill results on twinned holes match previous 2017 drilling and the 1980s drilling. The mineralisation is repeatable and modellable, and the1980s drill hole data will therefore form part of the new MRE in our view; the cost of redrilling these extra holes would be significant. It will both add tonnage and increase confidence in the resource in our view. Continued reporting of high-grade assays mean this project is one of the highest grade tungsten projects in the world. Strategic view it as the highest grade in Europe and we would concur with that
