Annual report on EL 25379 Hays Creek for the period 21 February 2010 to 20 February 2011

Abstract

EL 25379 is located about 150 km SE of Darwin and about 55 km N of Pine Creek in the Northern Territory. EL 27364 was applied for on 19 May 2006 and was granted on 21 February 2007. The tenement was granted for a period of 6 years and will expire on 20 February 2013. It has 2 blocks encompassing 6.68 km2. EL 25379 is situated within the Pine Creek Orogen, a tightly folded sequence of Palaeoproterozoic rocks, 10 km to 14 km in thickness, laid down on a rifted granitic Achaean basement during the interval approximately 2.2-1.87 Ma. The sequence is dominated by pelitic and psammitic sediments with minor inter-layered tuff units which have been intruded by granite magma during Top-End Orogeny. Project area is dominated by the rocks of the Burrell Creek Formation which is part of the Finniss River Group. The Burrell Creek Formation mainly comprises interbedded shale, slate, phyllite, siltstone, greywacke and rare volcanolithic pebble conglomerate. It contains a number gold, base metals, uranium and tin deposits/prospects. Further north and south, lithologies of the South Alligator River are present which mainly comprised of slates, mudstone, phyllite, siltstone and greywacke along with minor beds of chert and tuff. This stratigraphic sequence has been intruded by Palaeoproterozoic granites towards north and south. During the year under review, the tenement was purchased from T. Downing and an appraisal of the project area was undertaken. Open file data were reviewed in order to assess mineral potential and previous exploration activities in the project area. In addition, Thundelarra Exploration Pty Ltd also completed a detail geological mapping of the project area and surroundings. In the next reporting period, open file reports review and data compilation will take place. Ground - truthing and ground radiometric survey of the project area will be undertaken in order to examine the prospectivity of the project area. A soil/rock chip sampling program will be also be conducted.
