Helicopter-borne reconnaissnace EL 23571 Reynolds Range October 2005

Abstract

Geological reconnaissance was carried out in the Reynolds Range (EL 23571) during October, 2005. Ironstone localities were derived from NTGS descriptions in the 1:250,000 Napperby map sheet and were identified and evaluated. NTGS geophysical data reprocessed by Southern Geoscience Consultants provided weak uranium channel anomalies that warranted further investigation. Ironstone occurrences were of low grade and of limited extent. Samples were assayed for a selection of base metals, rare earth elements and radiogenic elements. Base metals were slightly enriched and rare earth elements and radiogenic elements were in background concentrations. Kaolinitic occurrences in Tertiary weathered profiles and in Napperby gneiss were of significant extent. Samples were assayed for a selection of base metals, rare earth elements and radiogenic elements. Selected rare earth elements were enriched; radiogenic elements were slightly enriched in samples from the Napperby gneiss and in background concentrations in samples from Tertiary weathered profiles; and base metals were enriched in samples from Tertiary weathered profiles and in background concentrations in samples of Napperby gneiss.
