Multi-element geochemistry from soil, rock chip and RC drill samples demonstrate metal zonation consistent with intermediate to high sulphidation epithermal mineralisation, which is consistent with the tectonic setting for Wertago.
Epithermal Cu-Ag mineralisation is controlled by a complex array of structures formed during the Siluro-Devonian extensional tectonics forming the Mt Daubney Basin. The complex fault architecture generally conforms to a Riedel fault system, with the mineralised structures aligning along the NE-oriented R-shears. The potential for shoots to form in dilatant zones at both structural intersection points and jogs within the shears within the 30km long Mt Daubney Basin is considered high.
CRA exploration completed two diamond drillholes targeting underneath the historic Scopes Range Pb-Ag workings, returning 1.9m @ 9.5% Pb and 16 g/t Ag from 41.1m in DD92DL23 and 2m @ 1.28% Pb and 4 g/t Ag from 79m in hole DD92DL22.
No follow-up work has been undertaken on these prospects. No additional drilling has been completed on the magnetic feature linking Scopes Range Pb-Ag workings with the Bilpa Copper Mine along strike.
