Cornish Metals plc’s surface diamond drilling has intersected “multiple target mineralised structures” which could potentially increase resource in the Roskear area of the South Crofty tin mine project.
MINERALISATION
The 2,400-metre programme aims to test extensions to known mineralisation and evaluate several priority exploration targets.
Drill hole SDD26_001A reached a depth of 1,199.1m and “intersected zones of quartz-
tourmaline veining with visible cassiterite, sulphide mineralisation, and alteration consistent with the target mineralised system”.
The Canadian company said that the intersected mineralised structures included mineralised structures which host existing mineral resources.
Drilling additionally intercepted mineralised structures west of the current MRE “envelopes”, which revealed the potential to grow resource.
Samples will be sent to ALS Laboratories in Loughrea, Ireland, with assay results expected during June 2026
Cornish Metals next plans to drill hole SDD26_002, to target the same structures some 100m west of drill hole SDD26_001A.
Chief executive officer Don Turvey added: “The completion of drillhole SDD26_001A marks an important milestone in this targeted exploration drilling programme at South Crofty.
“While assay results are still pending, the visual indications of mineralisation encountered are encouraging and support our geological interpretation of continued mineralisation to the west of the existing mineral resource areas.
“This programme is designed not only to assess opportunities for future mineral resource growth, but also to sterilise key infrastructure areas incorporated within the current mine design.”
