Geophysics Update, Byrock Project, NSW | May 2025

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.
