Castillo Copper announces NWQ development targets

Highlights:

• Initial focus will be on the Big One, which has an inferred mineral resource estimate (MRE) of 2.1 million t @ 1.1% Cu for 21 886 t copper metal post-two drilling campaigns across 2020-21:
  • Factoring in a large conductor north of the line of lode, plus reconciling available geophysics and geochemical data, Castillo’s geological consultant has set an exploration target that ranges from 2 – 6 million t @ 0.6-1% Cu for 12 000 – 60 000 t copper metal.
• The Valparaisa Prospect comprises copper mineralisation across two horizons over a 6 km strike event, with the interaction of two intersecting faults suggesting a structurally controlled copper system that can potentially be drill-tested.
• At the Arya Prospect, there is a significant magnetic anomaly, south of a known graphite system (test drilled in late 2021), that shows potential to be a primary source of copper mineralisation.
• Meanwhile, final drill and auger assays, which are still pending, should define the potential scale of the rare earth element discovery at the BHA Project’s East Zone

Dr Dennis Jensen, Managing Director of Castillo Copper, said:

“With the macro-outlook for copper remaining upbeat, the Board has authorised the geology team to visit several prospects to identify new targets to test-drill. Key areas of focus include increasing the grade and confidence in the current MRE at Big One and the magnetic anomaly at the Arya Prospect. Given the large size of the NWQ Copper Project, the Board remains open to aligning with a strategic partner to further advance development work.”
