Partial relinquishment report for EL 28402 Ammaroo Phosphate Project 20 June 2011 to 27 April 2016

Abstract

The Ammaroo Phosphate Project is located 240 km southeast of Tennant Creek. The project area contains the 40 km-long, billion tonne Ammaroo Phosphate deposit, which is currently Australia's largest undeveloped JORC phosphate resource, the satellite Ammaroo South JORC resource, the Rockhole Prospect and significant greenfields potential in the east. An updated Ammaroo Phosphate Project prefeasibility has been announced and higher tenure applied for. EL 28402 is located in the central part of the project area. A voluntary partial relinquishment of 9 blocks from 31 is being made. The relinquished blocks are either modern alluvial material which is a shallow aquifer locally and is subject to flooding or potential host rocks that are probably too patchy, too thin and too weathered to contain economic phosphate. Some of the relinquished area is also a Zone of Conservation Significance. There has been no on-ground work what-so-ever on the blocks relinquished.
