EL 24606 Lake Lewis, Parial relinquishment report 28 December 2005 to 27 December 2011

Abstract

During the reporting period DYL and Toro performed reviews of the available historical and regional data. In 2007 Toro commissioned Fugro Airborne Services to undertake an airborne electromagnetic (AEM) survey. In 2011 DYL commissioned Fugro to undertake a second AEM survey designed to delineate subsurface palaeochannels around the periphery of Lake Lewis with the potential to host both calcrete and roll-front style uranium deposits. The survey was completed late in the reporting period and DYL is still awaiting a final report and data from Fugro. The Northern Territory Geological Survey has advised DYL that due to the small area of the survey that falls within the relinquished ground, DYL is not required to submit the 'cookie-cut' data at this stage. The areas selected for surrender were chosen on the basis of the failure to identify, through analysis of regional and historical data in conjunction with AEM survey data, any palaeochannels or drainages that could potentially host calcrete or deeper roll-front style uranium mineralisation.
