Revolver Resources has noted several high priority conductive responses at Dianne following an airborne-EM survey.

Revolver Resources (ASX: RRR) has identified multiple conductive anomalies across areas of the Dianne copper project in far north Queensland’s Hodgkinson Province following the completion of an airborne electromagnetic survey.

The high-resolution survey was conducted over 670 line kilometres of the underexplored tenement, which is hosted in deformed Palaeozoic shale and greywacke of the Hodgkinson Formation.

It is part of the company’s strategy of step-out exploration from the current Dianne deposit in the hunt for “look-alike” discoveries at a district scale.

The survey was commissioned through New Resolution Geophysics (NRG) Australia and delivered the first modern geophysical exploration within the Dianne region, complementing ongoing ground-based electromagnetic work.

Revolver is also screening the immediate area for new VHMS (volcanogenic massive sulphide) targets.

‘Late-time’ anomalies

Initial analysis of the survey results have identified a number of discrete yet prominent ‘late-time’ conductivity anomalies providing up to 10 high-priority bedrock anomalies.

The anomalies are believed to be consistent with an accumulation of sulphides and provide “compelling” shallow VHMS-style targets.

The position of one of the anomalies is coincident with the Dianne deposit and validates the exploration technique, approach and modelling used to identify VHMS systems.

A further encouraging survey outcome has been reinforcement of the conductive anomaly down-plunge of the existing Dianne pit.

Current modelling is expected to augment follow-up electromagnetic groundwork to locate planned drill holes.

Positive evidence

Revolver managing director Pat Williams said the survey results were positive in providing evidence of regional anomalies.

“Our integrated program of step-out exploration continues to deliver positive results in a region that has not previously been assessed by modern exploration techniques,” he said.

“We continue to build our understanding of the geology and mineralisation potential on this exciting project, and are now starting to see clear regional trends emerging.”

He said the successful program of work would allow the company to focus and accelerate ground activities on VHMS targets and progress them toward drill-ready targets in the near term.
