EL 28275 Marqua Annual Technical Report for the period 30 March 2011 to 29 March 2012

Abstract

The Marqua Project in the Northern Territory is located 400km east of Alice Springs and 300km southwest of Mount Isa (Figure 1). The area is highly prospective for minerals, with high grade phosphate drill intersections encountered and also occurrences of base metals and uranium. Rox Resources Limited holds four contiguous Exploration Licences in the area, EL 28275, EL 28276, EL 28611 and EL 28612. This report is for the first period of EL 28275 from 30 March 2011 to 29 March 2012. Previous exploration of the area identified five phosphate prospects over a strike length of 30 km with outcrops grading up to 39.4% P2O5 along the phosphorus bearing Cambrian age Thorntonia Limestone. The prospects occur near the southern extent of the Georgina Basin, which is rapidly becoming Australia's major hard-rock phosphate province. Exploration work completed during 2011 included a 552 sample soil program covering the 30 km strike length of the prospective phosphate horizon as well as a 29 hole RC drilling program totalling 1,902 metres. In addition familiarisation trips to all extents of the tenements were undertaken along existing station tracks, and a desktop review of the exploration potential of the area, which included a complete review of previous exploration and compilation of data from open file reports, was completed. The soil sampling identified continuous phosphate in soils between the Mauritania and White Hill prospects and drilling confirmed this with all holes between Mauritania and White Hill intersecting the phosphate horizon. Drilling at the Foss Hill, Coquina Creek and Library Ridge prospects, to the east of the Christmas Creek fault, has identified a steeply dipping phosphate horizon made up of a high grade chert horizon and a lower grade calcareous black shale. The high grade chert is outcropping and encountered close to the surface along the strike of the three prospects which takes its form as a 15 km east to west ridge of small white hills.
