Castillo Copper says its geology team is off to a flying start at the Big One deposit in North-West Queensland, hitting visible copper oxide and sulphide mineralisation at shallow depths.
After inspecting samples from the first seven drill holes, the team observed
visible copper oxide (malachite) and sulphide (chalcocite) mineralisation in wide intercepts up to 13m.
Subject to assay results, the observations potentially extend known copper mineralisation at depth and indicate there are underlying sulphides in the
transitional / supergene zone, the company says.
“Hitting visible copper oxide and sulphide mineralisation at shallow depths in the first phase of an extensive drilling campaign is exceptional,” Castillo Copper managing director Simon Paull said.
“More encouraging, however, is the indicative size of the intercepts at Big One deposit, which range from 9m to 13m in work undertaken to date.
“The Board is delighted with this early success and looks forward to receiving the assay results.
“More importantly, however, with a further 28 drill-holes to complete, there is still significant exploration upside ahead.”
Drilling at The Big One will be followed by an RC drilling campaign at the Arya prospect at the Mount Oxide project, comprising about 3432m over 14 drill holes.
The Mount Oxide project is located 150km north of Mount Isa near the old Mount Oxide copper mine.
