Partial relinquishment report for EL 30613 Singleton Phosphate Project 15 June 2015 to 11 March 2016

Abstract

EL 30613 is being explored for rock phosphate. It covers rocks intersected in waterbores near Singleton Station homestead which were previously interpreted by NuPower/Central Australian Phosphate to be prospective Cambrian carbonates and siltstones. Rum Jungle Resources undertook a detailed study of all available information on 14 waterbores in and near Singleton EL 30613. There are possibly up to five different aquifers in this area. Groundwater is present in modern creek alluvials, Cenozoic clastic rocks, various Cambrian Formations/lithologies with combinations of vuggy, fracture and clastic porosity, and in Proterozoic ?basement? rocks. The study carefully considered whether the Cambrian target stratigraphy is above or below the standing water level. This led to the conclusion that the northwestern half of the title, closest to the railway, is least prospective for Cambrian phosphate. There is little evidence that Cambrian rocks are even present in this area and, if they were, they would be below the watertable. An AAPA Register Search revealed five Recorded Sites each surrounded by relatively small Restricted Work Areas. In addition, as a result of previous work in the surrounding area, Rum Jungle Resources is aware of a large CLC area of restricted access, which is coincident with two of the AAPA sites. All these are in, or impinge upon, the area proposed for relinquishment. Consequently, 35 blocks are being partially relinquished from 56. No on-ground work was conducted on the area being relinquished. The southeast 21 blocks of EL 30613 with fewer restrictions on access, remain prospective based on the waterbore study, and are being retained. Access is good on existing tracks and the area could be drill tested with only a few holes when funds become available.
