EL 25402 Limbla Project Annual and final report for the period 2 March 2007 to 5 March 2013

Abstract

EL 25402 is located approximately 120 km east of Alice Springs in the southern part of the Northern Territory. EL's 25373 and 25554 were originally part of this tenement package but were surrendered in early 2010 and no longer form part of this reporting group. The project area is located over the contact between the Palaeoproterozoic Aileron Province of the Arunta Block to the north and the Neoproterozoic Amadeus Basin to the south. The project area has been previously explored for uranium, diamonds, base metals, gold and heavy minerals. The Tourmaline Gorge and Albarta Uranium prospects were the intial focus for Western Desert Resources Ltd in EL 25402. Work in previous years has included ariel radiometrics and magnetics on selected portions of EL 25402 and an Ariel EM survey covering the northern portion of the tenement, and subsequent ground follow up of both radiometric and AEM anomalies with rock sampling ground radioactivity testing. From that previous work no significant mineralisation or drill targets were identified. The Ariel EM processing identified 2nd and 3rd order anomalies but no Priority 1 anomalies were identified. During the 2011-2012 reporting period WDR and historical data were looked at again and a metallogenic map was produced which highlighted highly anomalous nickel, chrome and scandium values reporting from ultramafics. This desktop study, including interpretation of Google Earth satellite imagery, also highlighted the fact that ultramafics are likely to be more common across the northern part of the tenement than is indicated on available government maps. The work for the 2011-2012 reporting period also included the enlisting of an expert consultant (Bill Laing) to visit the area with WDR geologists, carry out a structural analysis of the entire EL, and then subsequently to produce a prospectivity map to guide WDR geologists in further exploration. This work highlighted three shear zones, the already identified Illogwa Shear Zone (corresponds to the Illogwa Schist zone), the Leaky Bore Shear Zone and the Albarta Shear Zone, as the most prospective areas to look for mineralisation. 36 rock samples were collected and assayed for multi-elements and gold during 2011-2012. A fairly extensive soil sampling program was planned but ultimately did not begin until January 2012. Work in the 2012-2013 reporting period focussed on the Illogwa Schist/Shear Zone and included the collection of 471 soil samples for Ionic Leach analysis and 156 rock samples for multi-element analysis. Sampling was primarily centred on existing AEM anomalies. Several gold anomalies were highlighted through the soil sampling, with each requiring further analysis of the associated multi-element data, and infill and extension sampling of the survey grids prior to the possibility of drill targeting. The tenement was surrendered at the end of the 2012-2013 reporting period because no drill targets had been defined and the company needed to be focussed elsewhere.
