Comprehensive drilling campaign gets underway at flagship Mt Oxide Project

• Arya & Sansa Prospects – the logistics & geology teams are concurrently finalising access, program design and site preparation to ensure optimally drilling several bedrock conductors (1) and will begin once work concludes at Big One Deposit
• Looking forward, with ample funding up to $13.5m post the recent placement (2), the geology team is honing in on drill-testing structurally controlled copper targets such as at the Eldorado and Valparaisa Prospects (3) (Appendix A)
• Finally, CCZ is delighted to announce that David Drakeley of geology consultancy, FieldCrew (4), has been appointed to manage the integrated exploration program across the Mt Oxide Project

Castillo Copper’s Managing Director Simon Paull commented: “Over the next few months the Board’s core focus is to maximise exploration efforts across our flagship Mt Oxide Project. More pointedly, with a plethora of highquality drillable targets, shored up by ample funding, the Board’s strategic intent to transform CCZ into a mid-tier copper group is set to gain considerable momentum.”

Castillo Copper Limited (“CCZ”) is pleased to announce that a comprehensive drilling campaign is now underway at the core Mt Oxide Project, within Mt Isa’s copper-belt, across three key prospects.

COMPREHENSIVE DRILLING CAMPAIGN AT MT OXIDE PROJECT

Work has now commenced on a comprehensive Reverse Circulation (RC) and Diamond Drilling (DD) campaign at the flagship Mt Oxide Project across three key initial targets:

• Big One Deposit – The program, which comprises 26 drill-holes for 2,828m, has been designed to test several new and existing targets, north-and-south of the 1,200m strike event, to extend known copper mineralisation. Following a recent Induced Polarisation (IP) survey and geophysics review, the drilling program was re-designed to ensure optimal results.
  In tandem with the current drilling program, a DHEM survey is being conducted that will enable further insights to be determined, especially the density of the underlying copper mineralisation.
• Arya & Sansa Prospects – Once work at the Big One Deposit is complete, the drilling team will move across to the Arya and Sansa Prospects (1), where several bedrock conductors have already been identified. Currently, the logistics and geology teams are finalising access, optimal drill program design and site preparation in readiness for work to commence

Structurally controlled copper targets
With the recent placement bolstering CCZ’s cash position to circa A$13.5m (£7.4m) (2), the geology team are assessing the merits of drill-testing the Eldorado and Valparaisa Prospects3 (Appendix A). As part of a comprehensive geological review, which has identified up to 21 targets (5) across the Mt Oxide Project, deposits such as Eldorado and Valparaisa were interpreted to be prospective for structurally controlled copper mineralisation.

Although further work needs to be undertaken, the geology team are now building up a forward pipeline of targets to explore once the current drilling program across the Big One Deposit, Arya and Sansa Prospects concludes.

Experienced exploration manager appointed

To optimally manage the exploration program, CCZ is delighted to confirm appointment of David Drakeley of geology consultancy FieldCrew Group4. Given the relative complexity of the upcoming drilling campaign at the Mt Oxide Project, FieldCrew Group was selected for its reputation for exemplary project management and attention to detail in delivering positive outcomes.
