EL 23687, EL 27317 and EL 27318 Lake Woods Final report 11 June 2003 to 29 April 2011

Abstract

The Lake Woods project is located 700 km south of Darwin and 200 km north of Tennant Creek. The project area is centred on the Ashburton Range which runs north-south along the eastern margin of Lake Woods, a large seasonal lake. The Stuart Highway passes through the centre of the area. The Geology of the region is represented by the Middle Proterozoic Renner Group sediments, which have been intruded by pre-Cambrian dolerite. Previous exploration within the district has focused on the potential for diamonds and base metals but has been limited due to poorly developed drainage and widespread alluvial and aeolian cover. The area was originally identified as conceptual target area based on proprietary methods and modelling conducted by Paradigm Geoscience Pty Ltd. Exploration and associated activities conducted on the relinquished ground in the period 11 June 2003 to 29 April 2011 consisted of: literature studies and compilation of historical exploration data; project planning utilising the historical data; Field geological reconnaissance and collection of alluvial stream sediment and rock samples; Preparation and mineralogical examination of diamond samples; reinterpretation of government magnetics-radiometrics data; airborne EM (TEMPEST) survey and subsequent geophysical modelling; reconnaissance geological mapping and follow up ground truthing of geophysical anomalies; and Aircore and diamond drilling.
