The Big One Deposit is at the company's mining lease near the historic Mt Oxide mine north west of Mount Isa.
The company told the ASX they increased the potential structural targets across the Big One Deposit providing compelling evidence that significant incremental mineralisation is located along fault structures rather than constrained within the trachyte dyke.
They said the survey results complemented legacy drilling to boost the geology team's understanding of the system apparent at the Big One Deposit:
"Several drill holes need to be extended to deeper depths to enhance the probability of intersecting underlying copper mineralisation and new locations and orientations are being made to the next phase of the drilling campaign - which is due to commence shortly - in order to achieve optimal results," the company said.
Simon Paull, Managing Director of Castillo Copper, said the results significantly enhanced the exploration potential of the Big One Deposit.
"The IP survey provides compelling evidence that known mineralisation extends beyond the line of lode both to the north and to the south. This includes an untested bedrock conductor that is significantly larger than the high-grade anomaly we drilled in 2020. We now have several new high-priority structural targets for the next phase of drill testing which is set to commence shortly," he said.
The geology team has finalised the drilling campaign for the Big One Deposit which will comprise 26 drill-holes for 2828m.
