Cullen Resources Ltd (ASX:CUL) has received preliminary interpretation of data from a helicopter-borne versatile time domain electromagnetic (VTEM) survey undertaken at its Wongan Hills base metals and gold project, 180 kilometres northeast of Perth.
Focusing on geochemical anomalies previously reported, the survey was flown by UTS Geophysics Pty Ltd and covered 266 line kilometres on east-west lines spaced at 150 metres, with a sensor height of 30 metres.
The results highlight multiple clusters and trends of interpreted bedrock conductors, which along with several coincident geochemical anomalies point to potential volcanic-hosted massive sulphides (VHMS) deposits.
None of the multiple geochemical anomalies with interpreted bedrock conductors have been the target of previous drill testing.
Ground EM to follow
Cullen managing director Chris Ringrose said: “We are very encouraged by the detection of bedrock conductors within an area prospective for VHMS deposits, where supported by strongly anomalous laterite geochemistry comparable to that of Golden Grove.
“We anticipate several drill targets to be refined from modelling of the VTEM data and follow-up ground EM (electromagnetic survey).”
Golden Grove-type deposit
The company believes Wongan Hills has a favourable geological setting for VHMS in an Archaean greenstone belt with known copper-gold mineralisation.
Laterite geochemistry has shown some similarities to that of the 50 million tonne Golden Grove VHMS system.
Modelling of the VTEM conductors, together with a field review, will prioritise targets planned for ground EM surveys next quarter.
Several of these targets warrant drill-testing but will require further permitting from landowners due to being situated on freehold farm land.
