Drilling commences at Arya Copper Prospect

Castillo Copper Limited ("CCZ"), a base metal explorer primarily focused on copper across Australia and Zambia, is pleased to announce that following the largest mobilisation effort in CCZ's history, drilling has now commenced at the Arya Copper Prospect, located in the Mt Isa copper-belt of Queensland, Australia.


-- The inaugural drilling campaign at the Arya Copper Prospect is now underway, after a massive logistical effort to prepare the drill-pads and heli-lift the rig and all supporting equipment to site

-- After reconciling the geochemical and geophysics data(1) , the Board decided to orchestrate a strategic "proof of concept" campaign, comprising five initial RC drill-holes

-- Key focus remains to drill-test the three targets identified by BHP in the mid-1990s including EG01, EG02 and EG10(1,2) :

o Of these, EG01 has been interpreted as a potential massive sulphide bedrock conductor 130m thick, 1,500m long and 450m wide at a revised 100-200m depth(1,2)

-- If initial observations and findings from the drilling are encouraging, the campaign will be expanded to fully-test the extent of any underlying system

-- Concurrently, the geology team will undertake a 200m-by-200m mapping / rock chip sampling campaign which is designed to extend the known surface anomaly to the south

Simon Paull, Managing Director of Castillo Copper, commented: "We are delighted to have commenced drilling at our Arya prospect. Of the 22 targets that we have across the tenure in the Mt Isa region, the Arya Copper Prospect has generated the most intrigue and interest among stakeholders. The geochemistry and geophysical evidence have all provided compelling evidence the three targets are potentially among the best within our tenure. As such, the Board optimistically looks forward to the initial observations as the campaign progresses."


Drilling is now underway at the Arya Copper Prospect after the largest mobilisation effort in CCZ's history. This entailed heli-lifting the drill-rig, all supporting equipment and personnel to site due to the rough terrain. After running several scenarios, heli-lifting all the equipment to site (and between drill pads) was calculated to be more cost efficient and flexible than building a reinforced, access road at this initial stage of the campaign.

Furthermore, post reconciling historic geochemical and geophysical data, the Board decided it was strategically more prudent to orchestrate a "proof of concept" campaign comprising five RC drill-holes initially which includes AR04, AR08, AR09, AR13 and AR21. If the first-round observations and geological findings are encouraging, there is built-in flexibility to expand the campaign to fully drill-test the extent of any underlying system.

The focus remains on drill-testing the three main targets that BHP identified in the mid-1990s comprising EG01, EG02 and EG10. Significantly, much of the emphasis will be on EG01 which is interpreted to be a potential massive sulphide bedrock conductor 130m thick, 1,500m long and 450m wide at a revised 100-200m depth(1,2) .

Additionally, the geology team will undertake a 200m-by-200m mapping / rock-chip sampling campaign which is aiming to extend the known historical surface anomaly to the south.

Next steps

In Queensland, the following is set to take place over the coming weeks:

   o     Progress reports on drilling at the Arya Copper Prospect. 

For the lithium projects:

o Ongoing due diligence for the Picasso and Litchfield Lithium Projects, including return of assay results for surface sampling campaigns.

There are several ongoing steps for the Zambia operations, including:

o Complete the IP survey at the Luanshya & Mkushi Projects then analyse the results for incremental targets for test-drilling; and

   o     Commence work on the inaugural drilling campaign for the Luanshya Project.

About Castillo Copper

Castillo Copper Limited is an Australian-based explorer primarily focused on copper across Australia and Zambia. The group is embarking on a strategic transformation to morph into a mid-tier copper group underpinned by its core projects:

-- A large footprint in the Mt Isa copper-belt district, north-west Queensland, which delivers significant exploration upside through having several high-grade targets and a sizeable untested anomaly within its boundaries in a copper-rich region.

-- Four high-quality prospective assets across Zambia's copper-belt which is the second largest copper producer in Africa.

-- A large tenure footprint proximal to Broken Hill's world-class deposit that is prospective for zinc-silver-lead-copper-gold.

-- Cangai Copper Mine in northern New South Wales, which is one of Australia's highest grading historic copper mines.

The group is listed on the LSE and ASX under the ticker "CCZ."
