Gascoyne, Western Australia

Summary

Lithium Australia NL (‘LIT’) holds 100% equity in the Gascoyne project, which consists of five granted exploration licences (see Figure 1). The four contiguous tenements are in the name of wholly owned subsidiary Lithophile Pty Ltd. The occurrences within LIT’s ground have not previously been assessed for lithium, despite exhibiting exceptionally favourable geological characteristics.

Geology

The project area, which lies along strike and adjacent to the Nardoo Pegmatite District, is spatially associated with peraluminous S-type granitoids. Peraluminous granites are thought to be generated by partial melting of older sedimentary rocks. Of interest are the Thirty-Three and Durlacher Supersuites, which are the possible source of the extensive pegmatites swarms of the district.

Documented lithium, rubidium, and niobium geochemical anomalies, as well as tantalum, tungsten and tin occurrences, occur within the Gascoyne project. These have not been explored in recent times and will be the focus of LIT’s preliminary geological reconnaissance.

Results of exploration/testing/development

A GIS data package of all open-file geophysical and geological data, assembled in November 2016 by Southern Geoscience Consultants (‘SGC’), has enabled LIT to generate targets for ground geological reconnaissance and sampling on most of its WA projects. It is currently anticipated that SGC’s GIS data package will generate additional targets for the Gascoyne project.
