Highly encouraging initial reconnaissance surface sample results of up to 0.39% lithium oxide have been returned from pegmatite bodies on the recently optioned Dulcie Heap Leach Gold Operation (DHLGO) tenure.
This marks the beginning of an initial assessment of the lithium potential of the area in conjunction with its systematic screening of the large Split Rocks project.
The emerging lithium district is host to SQM-Kidman Resources Ltd’s (ASX:KDR) Mt Holland/Earl Grey lithium deposit containing 189 million tonnes at 1.5% Li2O.
KDR is the subject of an off-market takeover by Wesfarmers Ltd (ASX: WES).
Map showing regional lithium projects
The DHLGO ground is east of Zenith’s Dulcie lithium target, where aircore and reverse circulation (RC) drilling confirmed thick pegmatite bodies.
Zenith has a two-year option to explore for bedrock gold and lithium mineralisation on tenements covering the operational DHLGO area in exchange for surface laterite gold rights on the company’s adjoining exploration licence E77/2388.
Broad anomalous levels of lithium were recorded throughout, including 79 metres at 284ppm lithium oxide with a peak value of 1 metre at 1072ppm.
Split Rocks lithium prospects and anomalies
The company’s drilling programs will test both pegmatite bodies identified in historical drilling, surface lithium anomalies generated via the company’s work programs and bedrock gold targets.
Lithium sampling details
Initial reconnaissance sampling included the collection of 40 samples of selected intervals of historical RAB, AC and RC drilling as well as surface rock sampling.
The sample identified is a surface rock sample from a small exposure of pegmatite, possibly exposed in an historical mine working.
It is rich in mica and not indicative of spodumene-bearing pegmatite at surface but the high lithium content (0.39%) with anomalous cesium (106ppm), rubidium (2270ppm) and tantalum (35ppm) is encouraging.
These levels commonly occur in evolved pegmatites capable of forming spodumene mineralisation.
