Final Report EL 28847 Cox River East for the period 20 February 2012 to 20 October 2014

Abstract

This report covers activities on EL 28847 which was granted on 20th February 2012 for a period of six years to Australian Manganese Resources Pty Limited. EL28847 forms part of Group Tenements GR 270/13 (ELs 28587, 28605, 28606, 28847, 28848, 28898) which were granted to Australian Manganese Resources Pty Ltd (AMR) at various dates in 2011 and 2012. Group reporting applies from 12/02/2012. This report is the Final Report for EL28847 which was surrendered back to the Department of Mines and Energy on 15th September 2014. The Project lies within the Bauhinia Shelf of the Proterozoic McArthur Basin. The area has been historically subject to very limited exploration for manganese and other commodities by airborne geophysical methods at wide spacing that provides only basic information for an initial understanding. The tenements are situated within the McArthur Basin, a major Proterozoic-aged sedimentary basin. In Cretaceous times a major marine transgression laid down a sequence of sandstone, siltstone and conglomerate un-conformably over older rocks. Much of this sequence has been eroded with flat top mesas remnant in inland areas and cover (up to 100m thick) on coastal plains. Those portions of the tenements which are underlain by Cretaceous age sediments are considered to be prospective for manganese similar to that mineralization style found on Groote Eylandt. Very little field exploration was carried out during the life of this tenement due to other commitments in the area. However a comprehensive and complete review of all available data and deposit styles was undertaken as well as an inspection of all appropriate airborne geophysical methods and data sets available that might apply to the discovery of Manganese deposits under shallow cover. At the conclusion of this exercise it was agreed that manganese style mineralization may be evident but the exploration license evaluation did not suggest any deposits of note.
