Castillo Copper Limited (ASX: CCZ) has verified potential for shear-hosted copper-zinc-lead mineralisation with new work on the Johnnies prospect, within the Mt Oxide pillar in Queensland.
Managing Director, Simon Paull, said that incrementally, fresh evidence has been uncovered that highlights the potential to host supergene mineralisation.
He said there are now two prospects with supergene mineralisation potential at the Mt Oxide pillar, along with four IOCG, two Mt Isa style and several other targets.
Castillo has commissioned an independent geological consultant to review all eight prospects at the Mt Oxide pillar, since they all have potential to deliver high-grade, near surface deposits suitable for multiple open-pit operations that could provide feedstock ore for third party processors.
To date, of the reviews conducted, there has been sufficient historic geochemical and geophysical data to determine preliminary test-drill targets.
The ongoing review of the Mt Oxide pillar continues to uncover excellent news, with verification there is potential for supergene ore at the Johnnies prospect which complements known shear-hosted copper mineralisation,” Mr Paull said.
“CCZ’s current objective for the Mt Oxide pillar, which is to map out an extensive set of walk-up drill-test targets across eight prospects, is rapidly taking shape.”
At Johnnies an historic induced polarisation survey identified two anomalies:
- a low phase response that is potentially sulphide mineralisation continuing down plunge; and,
- a north trending downwards plunging anomaly.
Across the Johnnies prospect significant anomalous assayed surface samples have been associated with shear-hosted copper-lead-zinc mineralisation. Moreover, the interpreted shear zone, which is circa 1,550m by 400m and orientated north-east.
Castillo Copper’s London-based Director, Gerrard Hall, said the news at MT Oxide continues to be very positive.
“Like a good novel, the Mt Oxide pillar story continues to get better and better as another piece of positive news from the prospect review is uncovered.
“Indeed, based on the review’s current trajectory, a significant forward pipeline of drilling work is set to materialise.”
