• 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.”
