RESULTS AND NEXT STEPS
Positive results from IP geophysics surveys have identified a significant chargeability anomaly at CS03, indicative of sulphides at 120m depth.
• Next steps include ground truthing, mapping, geochemistry and close spaced surface geophysics surveys to confirm drill target(s)
Positive results from the airborne magnetic survey have identified six new “pipe-like” high-mag response prospects as potential Cu-Au porphyries.
• Next steps include infill gravity data acquisition and mapping
• The gravity survey will be used to distinguish felsic intrusions from mafic intrusions, with felsic intrusions considered more prospective
• Gravity surveys are a cost-effective tool to filter these six new targets
Passive seismic and IP results on Cu-Au porphyry targets T47 and T55
• T47 Prospect: passive seismic confirmed the shallow 65m depth and was effectively tested using IP geophysics, but no sulphides are interpreted
• T55 Prospect: located 80km east of the main project area has >200m of black soil cover over the large-scale Cu-Au porphyry target T55 and the IP survey was ineffective due to the conductive black soil cover. A passive seismic survey confirmed crystalline basement at 300m depth
• A gravity survey is planned to validate the high-reward T55 drill target
The first phase of field recon and geophysics surveys to validate drill targets has been completed at the newly acquired Byrock Project in the Lachlan Fold Belt, NSW.
We were initially drawn to the project due to the number of targets and different mineralisation styles identified. We are pleased that the exploration methods deployed have proven effective, particularly over the shallow covered areas. Importantly, we believe we can improve the confidence in the drill targets with another round of targeted, cost-effective boots on the ground mapping, geophysics and soils programs. We’re also encouraged to see that our robust evaluation process, leveraging technology and the expertise of the team, has been effective in ruling out several targets prior to committing funds to drilling programs, leaving only targets that align with Copper Search’s criteria for economic scale potential. In addition, Professor David Selley and Dr Paul Kitto have now completed a valuable desktop tectonostratigraphic review of the region to enable our team to see the bigger picture of the structural controls and sharpen the focus our next phase of exploration efforts.
Where targets of sufficient scale and reward occur deeper, such as the Cu-Au Porphyry T55 Prospect (~300m depth) – we intend to de-risk exploration and apply for NSW Government co-funded grants.
The project remains open for orogenic gold, Cu-Au porphyry and Cobar-style mineralisation. I am pleased with the progress as we work through the validation stage ahead of planned drilling of the best targets later in the year.
