GR323 Annual Technical Report Mountain Creek Exploration Project for period ending 16 April 2015

Abstract

Exploration Licence 29484, 29510, 29670 and 29762 of the Mountain Creek Project covers prospective ground around the Union Reef goldfield. The tenements are about 168 km from Darwin via the Stuart Highway. This is the second annual technical report for the Mountain Creek project and covers exploration activities from 17th April 2014 to 16th April 2015. 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. Exploration activities for the reporting period included desktop reviews and data validation of historic exploration data.
