Castillo Copper’s geology team has pegged 35 drill-sites at the Big One
deposit in North West Queensland, ready for the upcoming drilling campaign.

In addition, the company says the team found visual evidence of supergene and massive sulphide mineralisation at surface, and potential linkages indicating Big One could be part of a larger IOCG mineralised system.

“The insights the geology team were able to gather at site are outstanding, especially visual evidence there is high-grade copper mineralisation across the Big One deposit,” Castillo Copper UK director Ged Hall said.

The team collected 24 rock chip samples along strike from stockpiles and historic pit workings which visually confirmed the presence of supergene oxide (malachite) and massive sulphide (chalcocite) mineralisation at
surface.

The geology team’s next task is to peg the Arya prospect, then undertake a closer review of the surface geology, as part of the process to progress concurrent drilling campaigns.

Big One and Arya are part of Castillo’s Mount Oxide project, near the historical Mount Oxide mine in the Mount Isa copper-belt district.

Castillo said an extensive tender process to find a suitable drilling contractor had been narrowed down to two short-listed candidates.
