My guess would be Waratah (near Yalgoo). Below is quote from ZNC report 3rd November 2021 (page 1).

"Drill contractor secured to test large-scale lithium-cesium-tantalum (LCT) pegmatite target at the 100% owned Waratah Well project in Western Australia. Extensive outcropping highly fractionated, prospective LCT pegmatite dykes with very high-grade tantalum (up to 1,221 ppm Ta2O5) and local high-grade lithium (up to 2.09% Li2O) extending over large surface area (3km x 2km). A total of 7 initial wide-spaced (1km spacing), 200m deep RC drill holes is scheduled to commence in early Dec-21. Drilling is anticipated to take approximately 2 weeks to complete with assay results anticipated 3 to 4 weeks thereafter."
