Castillo Copper Ltd (LSE:CCZ, ASX:CCZ) has finalised targets for the upcoming drilling campaign across four prospects at the East Zone of the BHA project in Australia.
The upcoming drilling campaign comprises one diamond core and 17 reverse circulation holes for 2,100 metres, with depths ranging from 100 metres to 160 metres.
Two drill-holes have been earmarked for The Sisters, with the balance across the Fence Gossan, Reefs and Tors Tanks prospects.
For the Fence Gossan, Reefs and Tors Tanks Prospects, the campaign has been designed to penetrate deep enough to intersect two lower cobalt-rich zones thought to host higher grade mineralisation.
Castillo's geology team believe there is potential to extend known mineralisation. The resource currently stands at 21,556 tonnes of cobalt and 44,260 tonnes of copper.
A drilling contractor will be appointed shortly and a start date announced, once regulatory approval is secured.
"The board's strategic intent with the upcoming drilling campaign is to extend known cobalt mineralisation as well as enhance the confidence and grade of the current mineral resources estimate,” said Dr Dennis Jensen, managing director of Castillo Copper.
“Further, with the geology team having undertaken extensive due diligence across the East Zone, the board is confident the targets selected for test-drilling should significantly deepen our understanding of the underlying system."
The objective of the campaign is to extend known mineralisation primarily for cobalt, then copper, rare earth elements and gold.
