Annual report for EL 25681 Roper River 18 September 2009 to 17 September 2010

Abstract

Exploration License EL 25681 is located on the banks of the Roper River and is entirely with Goondooloo Station. It has been explored by Tianda Resources (Australia) Pty Ltd for uranium and iron ore since being granted in September 2007. The outcrop lithology in the tenement is comprised mostly of Proterozoic Roper River Group sediments, being sandstone and siltstone of the Velkerri, Moroak Sandstone and Kyalla Members of the McMinn Formation. The Sherwin Ironstone Member is sometimes found between the Moroak and Kyalla Members, and was the focus of the iron ore search. During July 2010, geologists of both Tianda Resources (Australia) Pty Ltd and the consultancy, Terra Search Pty Ltd, worked on the tenement. Exploration was conducted with the assistance of Google Earth imagery, seeking out hilltops that might be ferruginized. Nine geochemical samples, fifty geological observation points and sixteen outcrops of Sherwin Ironstone Member were taken. All locations were recorded on Garmin GPSs using GDA94 projection. Data files were exported from the GPSs and processed and displayed with Mapinfo. The sixteen outcrops of Sherwin Ironstone Member varied in area from less than 0.1Ha to a maximum of 2.4 Ha, with a median of 0.1Ha. They were all located on or near the tops of hills comprised of Moroak Sandstone Member and were between 0.5 and 2 metres thick, with a total area of about 9 hectares. ICP-OES analysis of the nine rockchip specimens gave values in the range of 11.9% Fe (in ferruginised sandstone) up to a maximum of 43.9% in oolitic ironstone. The median grade was 34.2%. As both the tonnage and grade of iron ore within the tenement is far below economic cutoff, it is recommended that the tenement be relinquished.
