Annual report for EL 25290, for the period 23 July 2007 to 22 July 2008

Abstract

This report describes exploration activities carried out on EL25290 in the southwestern part of the Georgina Basin between 23 July 2007 and 22 July 2008. A preliminary published literature study was carried out during the year to assist with planning of future geological investigation. The tenement is a part of the Barrow Creek and Alcoota 1:250 000 map sheets. The major tectanostratigraphic units of the region are the northern Arunta Inlier, Davenport Province of the Tenennant Creek Inlier and the southwestern and southern parts of the Georgina and Wiso Basins respectively (Haines et al., 1991). The geology of the tenement consists of two Palaeozoic formations belonging to the Georgina Basin succession and overlying Quaternary cover. These formations are Tomahawk Beds and Dulcie Sandstone. The geological description of the formations given below has been derived from Haines et al., 1991. The mineral prospects in the Neoprotoerozoic to Palaeozoic Georgina Basin are base metal and phosphate plays. There are known occurrences of Pb-Zn mineralization throughout the Basin sequence representing wide range of styles. Similarly economically significant phosphate deposits have been discovered at various localities particularly in the central and eastern parts of the basin. During the reporting a period preliminary review of published literature has been undertaken to assess the area's mineral potential. This is to be supplemented by detail review of published material and information from open file reports. On completion of this task a comprehensive exploration plan will be. After a review of pre-existing exploration and published research work, it is suggested that field mapping of the areas of interest should be carried out to define suitable target regions for further geological and geochemical investigation.
