Second Annual Report for EL 30613 Singleton Phosphate Project, 15 June 2016 to 14 June 2017

Abstract

EL 30613 is being explored for rock phosphate. The EL 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. During Year 1 of tenure, Rum Jungle Resources (as the company was then), 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 original title, closest to the railway, was 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. Consequently, based on the waterbore study and no-go areas, 35 blocks were voluntarily relinquished from the original 56 within the first year of tenure. The southeast remains prospective based on three waterbores and this area still warrants drill testing. Drilling would be constrained by a CLC Cultural Site, but overall, sufficient area remains to justify a modest drilling program if undertaken in conjunction with other work in the nearby Ammaroo Project. No on-ground work was undertaken in Year 2. The area could be drill tested with only a few holes when funds become available.
