Final report SEL 10341 Union Reefs Project for year ending 29 September 2011

Abstract

SEL 10341 is located 165km SE of Darwin NT and 20km north west of Pine Creek and abuts the Union Reef group of tenements toward south. The licence expired on 29 September 2011. An application for ELR29039 was submitted on 29 September 2011 to cover this tenement. SEL 10341 was originally granted to AngloGold (Ashanti) Australia Ltd on 30 September 2003 and was transferred to the Burnside JV subsequent to purchase of the mill and tenements in August 2004. GBS Gold Australia Pty Ltd took over Buffalo Creek Mines Pty Ltd and Territory Goldfields Pty Ltd (Burnside JV) in 2005. Crocodile Gold acquired the SEL 10341 in 2009 after GBS Gold Australia (liquidated) when into voluntary administration. The tenement area covers the Burrell Creek Formation with dominant lithologies of greywacke, siltstone and mudstone. Towards the north-west, minor rocks of the Mount Bonnie Formation (South Alligator Group) are also exposed. These lithologies have been intruded and thermally metamorphosed by the Tabletop, Allamber Springs and McKinlay Granites. The central part of the tenement is transected north-northwest to south-southeast by the Pine Creek Shear Zone, a grossly antiformal zone averaging 300m wide, characterised by phyllitic schist and tightly compressed folds. The axial zones on the principal anticlines have frequently failed within the PCSZ and predominant bedding and fabric attitudes are steeply dipping to the north east. Some parasitic folds have steep westerly dips. The PCSZ is the most mineralised structure with respect to gold in the region and host many gold deposits such as Union Reefs, Enterprise, International, Gandys, Czarina, Spring Hill and may more prospects. From 2003 to the licence expiry in September 2011, exploration activities on SEL 10341 have included desktop and literature reviews, a remote sensing study, data compilation, reconnaissance mapping and field visits, RC drilling and assaying and the purchase of new satellite images.
