HIGHLIGHTS
The large intrusive feature is coincident with previously reported high grade Nb-Y-REE results from eluvial samples and high priority soil geochemical anomalies.
Located in the highly prospective Gascoyne “Battery Metals” Province of Western Australia, approximately 150kms north of Gascoyne Junction, the Wabli Creek project has provided high grade niobium and TREO results up to 32% Nb2O5, 14.3% Nb2O5 and 2.6% TREO. (ASX Announcement 13 Dec 2022, 1 June 2023).
The newly identified ovoid magnetic feature is interpreted to be a younger granitic sequence which has intruded into the older, regionally extensive, Durlacher Supersuite, proximal to the Chalba Shear Zone, a major E-W trending structural corridor.
Importantly, the existing 3 highest priority geochemical anomalies, together with the area historically mined for high-grade niobium eluvium all occur along the margins of this newly identified feature, suggesting a potential genetic link between the intrusive and known mineralisation.
This is the first time that such a potential link has been indicated at Wabli Creek and if correct, it expands the potential of the project to host significant Nb-Y-REE mineralisation.
Geophysical Surveys
Southern Geoscience completed a review of all available geophysical data over the Wabli Creek Project area, with the aim of producing a structural interpretation based on public domain airborne magnetic data, radiometric data and satellite imagery. The key outcome following the study was the identification of a large “ovoid-shaped” magnetic feature central to E09/2377(Refer to Figures 1 and 2).
Importantly, a total of 27 targets have now been identified and will be the focus for ongoing exploration at Wabli Creek, for Niobium-Yttrium-Rare Earth Elements.
Given the success of the geophysical review, and the relatively low resolution of the existing magnetic and radiometric surveys at Wabli Creek (~400m line spacing, 80m station spacing), detailed airborne geophysical surveys including magnetics, radiometrics and gravity are now planned to further refine priority targets and to potentially identify additional exploration targets.
Jeremy Bower CEO commented:
“The identification of a potentially late stage, younger, granitic intrusive sequence at Wabli Creek is really exciting.
We have previously reported some very high grade Nb-Y-REE rock chip and soil results at Wabli Creek, and having now located what may be the source of mineralisation, could potentially be of significant importance in understanding the source of the mineralization at the project.”
