- Castillo Copper (CCZ) has finalised its latest drilling campaign for the Big One Deposit within the Mt Oxide Project in northwest Queensland
- The campaign will comprise 26 holes drilled over 2828 metres and aims to collect detailed assays, density and geotechnical measurements
- The upcoming work will factor in a recent geophysical survey to extend the known mineralisation and build on prior results from the deposit
- Once the expanded work at Big One is complete, CCZ will move its focus to the Arya and Sansa prospects, where it has identified prime test drill targets
- CCZ’s drilling crew is expected to deploy to Big One within one to two weeks

Castillo Copper (CCZ) has finalised its latest drilling campaign for the Big One Deposit within the Mt Oxide Project in northwest Queensland.
The campaign will comprise 26 drill holes over 2828 metres, including 108 metres of HQ diamond coring in two holes, aimed at collecting detailed assays, density and geotechnical measurements.
Comparatively, Castillo’s 2020 program totalled 21 reverse circulation drill holes for 1467 metres.
The company says the upcoming drilling will factor in a recent geophysics survey that comprised six 500 to 700-metre lines across 1200 metres of strike.
In this way, CCZ hopes its latest program will extend the known mineralisation and build on prior drilling results from the deposit.
Previous intercepts include 44 metres at 1.19 per cent copper from surface, including 14 metres at 3.55 per cent from 27 metres, three metres at 10.88 per cent from 37 metres and 12.6 per cent from 37 metres.
Arya and Sansa prospects
Once the expanded campaign at Big One is complete, CCZ will move its focus to the Arya and Sansa prospects.
In preparation for this phase, Castillo’s geology team is reviewing all key data points to ensure the highest probability of success.
Across the two prospects are several inferred bedrock conductors, which CCZ considers to be prime test drill targets.
Additionally, surface soil and rock chip copper anomalies reportedly support two shallower conductors.
Castillo Copper Managing Director Simon Paull commented on the work ahead.
“Reconciling geophysics findings with legacy drilling and geochemical data should enable CCZ’s geology team to design effective drilling campaigns for the Big One Deposit, Arya and Sansa Prospects with a high degree of confidence,” he said.
Next steps
Looking forward, Castillo’s geology team is working to ensure logistics are in place so the company’s drilling crew can deploy to site within one to two weeks and work at Big One can commence.
Concurrently, the company is finalising the design of its drilling program planned for the Arya and Sansa prospects.
Shares in Castillo Copper are trading steady at 4.9 cents at 10:16 am AEST.
