GCX Metals identifies 10km-long lithium anomaly ‘directly within the shear’ at Southern Cross

A 10km-long x 2km-wide lithium anomaly has been identified from 1,770 soil samples
Southern Cross is north of Covalent Lithium’s giant Mt Holland project
An infill program is planned across the soil sampling area

Special Report: A whopping 1,770 results from renowned CSIRO UltraFine soil sampling has identified a 10km-long lithium anomaly at GCX Metals’ Southern Cross project in WA.

GCX Metals’ (ASX:GCX) 800km2 Southern Cross project lies along trend of the greenstone belts to the north and south of Southern Cross, including Covalent Lithium’s giant Mt Holland lithium operation (186Mt @ 1.53% Li2O) and Zenith Minerals’ (ASX:ZNC) Split Rocks project (11.9Mt @ 0.72% Li2O), both within the Southern Cross domain.

A lithium anomaly with significant scale potential

The anomaly is coincident with a major fault structure associated with the Koolyanobbing shear zone – a large northwest‐trending, crustal‐scale, ductile shear zone in the Archaean granitoid‐greenstone terrain of WA’s Yilgarn Craton.

Assays revealed a large continuous ~10km x ~2km lithium anomaly coincident with the mapped northwest trending structural features.

A maximum soil result of 171ppm Li2O was discovered which the explorer says is considered highly anomalous.

The company says it will now accelerate a program to infill the anomaly down to 250m x 250m spacing to further identify targets.

‘Lithium fits well into our developing portfolio’

GCX managing director Thomas Line says the Southern Cross project is a grass roots, district-scale lithium play which sits on a highly prospective lithium trend, hosting the Tier 1 Mt Holland Lithium deposit 170km to the south.

“We are very pleased to have secured over 800km2 of an unexplored shear zone in the Archaean granitoid‐greenstone terrain of WA, a region with striking structural geological similarities to Greenbushes,” Line says.

“To reveal a large and coherent lithium anomaly directly within the shear is a satisfying proof of geological concept.

“As a diversified critical metals explorer, lithium fits well into our developing portfolio. We look forward to refining the anomaly with infill sampling.”
