(Partial) Surrender report for EL 24995 Kurundi Prospect

Abstract

This report describes the work undertaken by Washington Resources Limited (WRL) in assessing the granted exploration licence 24995, located 110 km southeast of Tennant Creek in the Northern Territory. The tenement covers a gap in tenure 18 graticules long by 150m wide and was explored in conjunction with EL 23937. Access from Tennant Creek is 80 km south via the Stuart Highway, then some 70 km east to the Kurundi Station homestead by way of the main station access road. Access within the tenement is via mine roads and well-maintained tracks, or cross-country. The tenement area is located along the eastern margin of the Tennant Creek Inlier. This is an intensely folded, early Proterozoic intra-cratonic basin succession of mainly sedimentary and minor felsic volcanic rocks, intruded by younger granitoids. This inlier which forms a north-northwesterly trending belt some 700 km in length is centred on the town of Tennant Creek and comprises Palaeoproterozoic sediments of the Warramunga Group, Hatches Group and Tomkinson Creek Beds. The Warramunga Group, which contains all the economically viable gold deposits currently mined in the Tennant Creek region, consists of a sequence of argillaceous sedimentary rocks, including siliceous greywacke, siltstone and shale. Quartz-feldspar porphyry lenses occur as both crosscutting and conformable units within the sedimentary sequences. The Warramunga Group has been the subject of at least three deformational episodes. No previous work is documented on that portion of the ground released and no work was undertaken on the area of the licence that was released.
