Key service provider appointments to accelerate developing new discovery at Big One Deposit

~ Following confirmation of the new high-grade copper discovery at Big One Deposit1 , within the Mt Oxide Project, the Board is expediting the next phase of development, especially with underlying mineralisation open in all directions

~ Geology consultancy, ROM Resources, has been formally appointed to leverage legacy and current data to model up a maiden JORC compliant inferred resource

~ In addition, GeoDiscovery Group, a geophysics consultancy, has been appointed to undertake an extensive geophysical survey, which has two core objectives:

        - Identify massive sulphide bedrock conductors along the 1,200m strike extent that potentially extends known mineralisation;

       - Provide geophysical insights into several known yet underexplored nearby anomalies which includes previously mapped gossanous outcrops to the north-east of the recent drilling campaign; and 

       - Once the survey results are known, the geology team should be able to further refine and optimise the drilling campaign to increase the probability of intersecting mineralisation 

~ CCZ’s geology team is currently working on a holistic update of Big One Deposit results, which is slated to be released imminently

~ Overall, the Board has been delighted with the results to date and is optimistic Big One Deposit has the potential to scale

Assays Confirm Major Copper Discovery at Big One Deposit

Game changing assays as two 40-44m wide potentially economic intercepts from surface, with up to 16.65%, significantly extends known mineralisation at the high-grade Big One Deposit

Key observations CCZ’s geology team garnered from interpreting drill-holes 301RC and 303RC include:

~The mineralisation is spread out which is significant given the trachyte to diorite dyke is generally 4-6m wide;

~ Secondary enrichment is apparent with several samples >10% Cu, likely due to intersected mineralisation occurring in the transitional zone between the oxide and sulphide domains; and

~High cobalt grades with 12m @ 912ppm Co fm 29m incl: 1m @ 1,435ppm Co fm 30m (301RC) o Further potential upside should become apparent when assays for drill-holes 307-14RC are received, as visible, shallow copper oxides & sulphides were intersected,

Divestment strategies being considered for Prime Broken Hill asset, prospective for IOCG & BHT mineralisation

The Board is currently liaising with its UK corporate advisor, SI Capital, on the optimal way to move this proposed corporate action forward in a timely manner o CCZ’s BHA (Broken Hill Alliance) Project comprises a large footprint proximal to the world-class Broken Hill silver-zinc-lead deposit

Castillo Copper’s Managing Director Simon Paull commented: “The resurgence of interest in the Broken Hill region is timely, as it provides an excellent opportunity for CCZ to optimise the BHA Project and create value for shareholders. Moreover, the ground is under-explored yet highly prospective for BHT and IOCG mineralisation, with multiple drill-test targets already identified.”

Castillo Copper’s London-based Director Ged Hall remarked: “The BHA Project is an excellent asset, as it comprises a substantial prospective footprint surrounding the world-famous Broken Hill silver-zinc-lead mine. We believe our intent to spin this asset out into a new vehicle will be well received and supported by UK investors.”
