The Eureka T09 soil sampling program has resulted in the delineation of a large-scale, well-defined, drill-ready REE target, which will now be referred to as the 'Adder target'.
The Adder target is approximately 450 m long and 250 m wide and is coincident with anomalous Thorium (Th) radiometric response. Thorium is used as an effective exploration targeting tool due to its association with the REE-bearing monazite mineralization identified at Eureka.
An in-situ soil pXRF survey was conducted on the Adder target on a tight 20 m by 10 m spaced sample grid. Approximately 72% of all points analyzed on the Adder target returned anomalous grades 500 ppm (0.05%) TREO in soil, with the highest returning 0.32% TREO in soil. The anomalous concentrations of REE found in the soil are consistent with the discovery of mineralized rock chip grab samples, providing further confirmation of this target.
The measured background REE concentrations are
