Cornish Metals plc, a mineral exploration and development company focused on advancing its wholly owned and permitted South Crofty tin project (“South Crofty”) in
Cornwall, United Kingdom, has announced positive assay results from the first drillhole of the ongoing surface drilling programme in the Roskear area of the South Crofty mine.

The programme comprises approximately 2,400 metres of diamond drilling designed to test extensions to known mineralisation and evaluate several priority exploration targets identified through historic drilling and recent geological interpretation.

Drillhole SDD26_001A, the first of two planned holes, has been completed to a final depth of 1,199.1 metres. Assay results have now been received and returned tin (“Sn”) mineralisation across multiple intercepts, consistent with the Company’s geological interpretation, and including mineralised structures that lie outside the current Mineral Resource Estimate (“MRE”).

Highlights
Assay results received for drillhole SDD26_001A, the first hole of the two-hole Roskear programme, returning tin mineralisation across multiple intercepts
High-grade tin intersections returned, including 0.79 metres at 4.18% Sn (Roskear 1 South) and 0.30 metres at 2.20% Sn (Roskear 3 North)
Broad 12.41 metre zone grading 0.43% Sn intersected in the Roskear Numbered Zone, including 1.90 metres at 1.32% Sn
The observed grades and structural positions are consistent with the Company’s geological interpretation
and provide additional confidence in the continuity of mineralised structures
Several intercepts, including two previously unmodelled (“unknown”) lodes and the Roskear Numbered Zone structures, lie outside the current MRE, highlighting potential for Mineral Resource growth to the west subject to further drilling
Second drillhole, SDD26_002, currently being drilled approximately 100 metres west of SDD26_001A and approximately halfway to its planned final depth

Lauren Beveridge, Chief Geologist of South Crofty, commented:

“These are very encouraging results from the first hole of the Roskear programme. SDD26_001A successfully intersected each of the targeted lodes, with grades and positions consistent with our geological interpretation, providing further confidence in our legacy sample dataset and underground survey.

“Just as importantly, several of the intercepts, including two previously unrecorded lodes, sit outside our current MRE, and we can see the mineralisation continuing to the west. Taken together, the results confirm the Roskear area as a high-quality exploration target with clear potential to add to our Mineral Resources. In addition, it provides additional confidence in our assumptions regarding resource replacement across South Crofty, which has the potential to significantly extend the life of mine. Drilling of the second hole is already well advanced, and we look forward to reporting those results in due course.
