Woomba Well Project
The Woomba Well license application area was identified by Castle through an interrogation of the GSWA critical minerals dataset (Report 233. SW Yilgarn Laterite 2020 Critical Metals digital data) was intensively interrogated to determine areas in Western Australia prospective for buried LCT (lithium, caesium, tantalum) pegmatites hosting possible undiscovered areas of lithium mineralisation.
Data was analysed for the suite of indicator elements considered characteristic of fractionated LCT pegmatites in order to finger print areas suitable for further follow-up and ranking. Elements such as lithium, beryllium, caesium, niobium, rubidium, tin and tantalum were statistically analysed to produce a prospectivity map outlining areas of interest.
The Woomba Well license area ranked extremely highly.
The area applied for lies along the northern margins of the Gum Creek Greenstone Belt within felsic intrusives of the Tuckanarra Suite and Yilgarn granites. Once granted, initial exploration of the area will consist of a surface geochemical program comprising soil sampling and possible air core drilling.
