Westar Resources Ltd (ASX:WSR) is designing a drilling program to follow up on a 1.4-kilometre lithium-caesium-tantalum (LCT) pegmatite strike at the Olga Rocks Project in Western Australia, intending to investigate three potential lithium-prospective corridors.
The company used surface mapping, rock chip sampling and a compilation of historical drill data to identify the pegmatite zone, which appears to be fractionated with multiple zones outcropping in two of the three corridors.
Drill hole data from historical hole OLC006 indicates the pegmatites are up to 38 metres wide in the central trend, and mapping activities observed pegmatites up to 35 metres in width in the eastern trend.
Gold data informs lithium exploration
“Westar is leveraging the historical gold drilling across the project to assist in defining the extent and thickness of the identified pegmatites, replicating the process Kidman Resources Ltd used in the early identification of the potential of the Mt Holland Project (now the Covalent Lithium Earl Grey mineral resource),” Westar Resources managing director Karl Jupp said.
“The process of using historical data has identified a central pegmatite zone with up to 1.4 kilometres of strike extent in addition to the confirmed eastern pegmatite zone and possibly a western pegmatite zone.
“We’re confident the initial rock chip sampling has identified these pegmatites as potential LCT-mineralised types and will progress fractionation targeting ahead of planning an initial RC (reverse circulation) drilling program to test the lithium potential of the pegmatites below the zone of weathering and lithium depletion.”
Apart from the follow-up drilling program at Olga Rocks, WSR also intends to complete:
- Detailed infill mapping.
- Additional rock chip sampling.
- Ongoing review of historical gold mining reports overlying the tenure.
- Assessing the western Parker Dome tenement for LCT pegmatite potential.
- Permitting and approvals prior to a maiden “Proof of Concept” RC drilling campaign.
