Zenith Minerals (ASX: ZNC) has begun drilling at its Split Rocks lithium project in the Yilgarn region with plans to test five large-scale geochemical targets in this 100+ hole first-pass drilling campaign. The Split Rocks project is 40km north of Kidman Resources’ (ASX: KDR) Mt Holland lithium project. A key focus of Zenith’s attention is the Dulcie prospect, a 950m long zone of pegmatites that returned strongly anomalous lithium results from shallow aircore drilling.
Five large scale lithium geochemical targets to be tested in ~100 hole first pass drill campaign;
Results awaited for re-sampling of anomalous lithium intervals from recent RC drill program that intersected thick pegmatite with basal section containing encouraging chemistry similar to known lithium pegmatite mines/deposits; and
A further 30 holes are planned to drill test surface laterite/gravel gold targets at Dulcie South.
Zenith Minerals Limited (“Zenith” or “the Company”) is pleased to advise that drilling has recommenced at the Split Rocks lithium project located 40 km north of Kidman Resources’ (ASX:KDR) Mt Holland (Earl Grey) lithium pegmatite deposit containing 189Mt @ 1.5% Li2O (KDR ASX Release 19th Mar 2018). Zenith’s 100% owned Split Rocks Project covers a large portion (total area >500sqkm) of the Forrestania Greenstone Belt of Western Australia (Figure 1).
As detailed in Zenith’s ASX releases on (17th April 2018, 14th September 2017, 4th December 2017, 6 th July 2018 and 14th August 2018) first pass surface samples taken at Split Rocks, to date covering approximately 20% of the Company’s tenements, have defined seven large, coherent lithium anomalies with variable levels of associated caesium, tantalum and rubidium surrounding granite bodies that may be potential source rocks for lithium bearing pegmatites (Figure 1). Three soil anomalies (Lithium Anomaly 1, 2 and 4) as detailed in ZNC ASX Release 6th July 2018 returned results up to 134ppm lithium.
The tenor of these large-scale lithium anomalies is comparable with competitor surface results that upon drilling have returned significant bedrock lithium mineralisation in several instances. Field follow-up indicated very little to no outcrop in the areas of the lithium soil anomalies and that drill testing will be required.
RAB drilling of lithium soil anomalies in the western portion of the Split Rocks project testing Lithium Anomaly 4 during the quarter was abandoned due to heavy rainfall after only one line of drilling (6 holes). The planned drill program will provide a first pass test of five of the lithium soil targets (Anomalies 1, 3, 4, 5 and 6) with around 100 drill holes anticipated to take approximately 2 to 3 weeks to complete. Further surface sampling is required to better define Anomaly 7 whilst additional sampling has been completed at Anomaly 2, results are awaited.
