Killi Resources (ASX: KLI) has commenced an Induced Polarisation (IP) ground geophysical survey at the two determined Cu-Au targets, Kaa and Baloo in WA.
The survey is designed to cover both targets which include historical workings, surface geochemical anomalies and VTEM geophysical targets. The survey will identify sulphide bodies beneath the geochemical targets, adding the last layer of information required prior to drilling.
Field mapping and surface rock chip sampling continues at the targets, with results to be released to market as they become available.
“We are excited to have started the IP Survey at Kaa and Baloo prospects. This geophysical survey shall deliver a 3D model across the targets, highlighting any sulphide units beneath the copper and gold seen at surface,” Chief Executive Officer, Kathryn Cutler, said.
“This geophysical technique has proven successful in other exploration programs targeting porphyry-epithermal copper-gold systems in Queensland.
“The targets generated from the survey may represent potential copper-gold bearing units beneath the surface, providing drill targets for the maiden drill campaign.”
The Mount Rawdon West Cu-Au Targets
The Baloo Corridor has been the initial focus of exploration, as geophysics highlighted a structurally complicated zone at the intersection of major regional faults, which are responsible for gold and copper mineralisation.
Soil samples and rock chips have focused across this corridor and returned large zones of both gold and copper enrichment at surface. In places the mineralisation has been of considerable grade, returning in assay, 7.2% Cu in bornite rich veins, 12.4g/t Au in quartz veins and 0.99% Mo from a quartz plug, all at surface.
Metal and element zonations have been determined for surface soil data and confirms the dominant metals at the project consist of a copper-gold-molybdenum core, flanked by bismuth-silver-tungsten, and more distally lead-zinc. This represents a typical geochemical assemblage of pathfinder elements, indicative of a fertile porphyry/epithermal system.
IP surveys have been proven successful in identifying drill targets for exploration of porphyry-style copper gold systems in Australia.
The ‘discovery hole’ completed at Cadia was the result of specifically and accurately drill targeting an IP anomaly.
The Kaa and Baloo targets are high priority and the focus of exploration efforts for the company.
