Litchfield Minerals Uncovers 100m of Copper-Zinc Mineralisation at Oonagalabi Project

Litchfield Minerals (ASX: LMS) continues to expand the copper mineralisation at its Oonagalabi project in the Northern Territory.

The 10th hole the company has drilled at Oonagalabi identified the potential for more than 100 metres of disseminated copper-zinc mineralisation, including several broad, higher-grade zones.

Litchfield achieved previous success at Oonagalabi, encountering mineralisation in every hole of a 6,150m program.

Testing RC Holes

The current drilling campaign at Oonagalabi, which Litchfield commenced in late September, is targeting as many as 14 reverse circulation holes for an estimated 3,750m, with geological logging and handheld X-ray flourescence (pXRF) readings key elements of the initial testing.

Highlight pXRF results included 104m at 1.37% copper equivalent, including impressive intersections such as 21m at 2.26% copper equivalent from 144m within a zone of 33m at 1.69% copper equivalent from 144m.

The company is now fast-tracking assays from the hole to gain more in-depth data on the presence of copper, gold, silver and other valuable elements.

‘Grades as Well as Volume’

“Hole 10 is a positive milestone for proving this system hosts grades as well as volume—over 100m of copper sulphide mineralisation, with multiple high-grade zones, is an outstanding outcome,” managing director Matthew Pustahya said.

“Seeing strong grades in a low-conductivity setting is particularly intriguing, and broadens our search window within the wider system.”

The company is now preparing to drill the VT1 and VT2 anomalies—the most pronounced, potentially sulphide-bearing features in its versatile time domain electromagnetic (VTEM) dataset.

“Independent review by VTEM Mitre Geophysics, supports a high likelihood of this having a sulphide source—this conductor is highly conductive and laterally extensive, with clear potential to host high-grade mineralisation,” Mr Pustahya said.

“We’re eager to put the drills on a rock chip taken directly above the VT1 conductor [that] returned gold, silver, copper and tellurium, pointing to the probability of this conductor containing metal,” he added.
