Castillo Copper is set to commence a comprehensive soil sampling campaign at its Big One Deposit, located within the NWQ Project in Queensland, Australia.

This initiative follows the reconciliation of promising historical exploration results, a resurgence in the copper market and optimistic forecasts from leading investment banks.

The Big One Deposit has a JORC 2012 compliant mineral resource estimate (MRE) of 2.1 million tonnes at 1.1% copper, equating to 21,886t of contained metal.

The company’s board has expressed a strong commitment to advancing the NWQ Copper Project, which features more than 20 known copper prospects.

Pending necessary approvals, Castillo Copper’s geology team plans to conduct soil and rock chip sampling north of the current orebody.

This area hosts a significant, yet untested, bedrock conductor. Previous explorations at the site have established the presence of the orebody, which originates at the surface and remains open to the north, east and down dip, but has not been fully delineated.

The geology team anticipates that the surface sampling results will provide sufficient data to design a drilling campaign. The aim is to potentially extend the known mineralisation at the Big One Deposit, thereby enhancing the project’s value and prospects.

Castillo Copper non-executive director and chief geologist Joel Logan said: “The ground north of the Big One Deposit’s line of lode, which contains a sizeable anomaly, is highly prospective. Indeed, drill-hole designs can be inferred via the nearby orientation of multiple extensions from confirmed highly mineralised lodes.

“Moreover, structural, petrographic and GIS analysis suggest the potential for shear hosted and IOCG-style mineralisation in the current areas of interest.

“With the presence of malachite, azurite and cuprite on the surface above potential targets, adjacent tenement holdings owned by majors, and the relative proximity to established and historic mine sites underpin the Big One Deposit’s exploration potential.”
