“Moving forward, the board’s goal is to concurrently progress developing the Queensland and Zambia projects, while bringing in third parties for the New South Wales assets.”

Castillo Copper Ltd - Castillo Copper is just days away from drilling its Queensland copper project

Castillo Copper Ltd (LSE:CCZ, FRA:7OR, ASX:CCZ) will mobilise its drilling crew will to the Arya Prospect in the final week of September 2021.

Ayra is the next prime prospect after Big One at CCZ’s Mt Oxide Project within the Mt Isa copper-belt of northwest Queensland.

CCZ will drill test key targets identified by BHP during the mid-1990s, including one estimated at 130 metres thick.

Drilling at Ayra will begin shortly after lead drilling contractor Down Force Drilling and CCZ’s drilling team arrive to site.

To ensure drilling begins on time, the rig and supporting equipment will be choppered to site.

Important primary targets

CCZ’s primary sulphide target at Arya is EG01 anomaly, which is interpreted to be approximately 130 metres thick, 1,500 metres long and 450 metres wide and 100-200 metres below surface.

Secondary targets include EG02 and EG10, which are ~25 metres below surface and interpreted to be approximately 25 metres thick, with dimensions at ~160 by 50 metres and ~270 by 280 metres respectively.

CCZ recently confirmed that all three targets – EG01, EG02 and EG10 – deliver significant exploration potential.

Arya Prospect including EG01, EG02 & EG10.

Big One assays expected next week

As CCZ readies itself for the Ayra drilling program, it is also waiting for assays to arrive from Big One Deposit.

Assays, coupled with interpretations from Big One, should be available next week.

The Big One Deposit is another key asset at Mt Oxide.

“The board is delighted to confirm mobilisation to the Arya Prospect during the last week of September 2021,” Castillo Copper’s managing director Simon Paull said.  

“Further, we look forward to shortly receiving the full assays and key interpretation work for the Big One Deposit.

“Moving forward, the board’s goal is to concurrently progress developing the Queensland and Zambia projects, while bringing in third parties for the New South Wales assets.”

What’s next


  • Commencement of drilling at the Arya Prospect, as all key service providers will deploy to site during the final week of September 2021.
  • Return of all Big One Deposit assays from the laboratory, which will enable the geology team to interpret the results then formulate the next drilling campaign.


  • Complete the IP survey at the Luanshya and Mkushi projects then analyse the results for incremental targets for test-drilling
  • Commence work on the inaugural drilling campaign for the Luanshya Project
