Highlights
- Several new areas with petalite-bearing pegmatites (up to 4.6% Li2O) identified at the Deep South Prospect. The footprint of mapped lithium-rich pegmatites (>1% Li2O) has now been expanded to a 450m x 450m area.
- Infill 50m x 50m soil sampling shows a very strong geochemical anomaly, up to 833ppm Li2O in soils, to be associated with the lithium pegmatites.
- The areas of mapped lithium pegmatites occur within an extensive and regionally significant >110ppm Li2O Ultrafine (UF) soil anomaly measuring about 1.1km x 1.75km with the potential for additional lithium pegmatites under cover.
- A programme of work (POW) has been approved in preparation for drilling at Deep South scheduled to commence on
The Deep South mineralization is a significant new lithium find situated in a poorly outcropping and under-explored area directly east from the crustal-scale
Project Background
Lithium mineralization was discovered by Venus following a regional Ultrafine (UF) soil sampling programme that outlined an extensive, 1.4km x 0.4km, northeasterly trending lithium geochemical anomaly (ASX release
Lithium-rich pegmatites with up to 4.6% Li2O were identified in three main zones (
Recent Results - Deep South
Recent field activities at the Deep South Prospect included field mapping and rock-chip sampling, in addition to the collection of over 600 new UF soil samples. Selected assay results for rock-chip samples (>0.1% Li2O) are presented in Table 1* and a compilation of soil sample results is shown as Figure 2*.
Geological mapping identified several new areas of sub-cropping lithium-rich pegmatite (>1% Li2O) peripheral to the previously reported pegmatite field (Figure 1*). The new data confirms that the exposed strike extend of
Based on the surface mapping,
The mapped lithium pegmatites occur within a much larger area characterised by significantly elevated lithium concentrations in surface soils. Recent exploration extended the broad-spaced 200m x 200m regional UF soil sampling programme and also included infill 50m x 50m sampling over previously defined geochemical anomalies (refer ASX releases
The UF soil geochemistry data (Figure 2*) highlights the central high-lithium anomaly (>200ppm Li2O; up to 833ppm Li2O), which correlates with interpretated areas of relatively thin basement cover within a broader >110ppm Li2O anomalous area (about 1.1km by 1.75km) that may reflect more extensive, thicker, cover over prospective basement rocks.
Regional Laterite Sampling
A regional laterite geochemical survey comprising 79 samples of ferruginous gravel was completed along the pegmatite trap zone at the southwestern margin of the Youanmi Greenstone Belt (refer ASX Release
Further Work
The results of the surface exploration programme at Deep South are considered highly encouraging and will be followed up with extensive drill testing. A programme of work (POW) has been approved by DMRS in preparation for planned drilling at Deep South to commence
