First Annual Report for EL 30613 Singleton Phosphate Project 15 June 2015 to 14 June 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 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. 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. Consequently, 35 blocks were voluntarily relinquished from the original 56 within the first year of tenure. The southeast remains prospective based on three waterbores. RN016797 - Prospective stratigraphy would be above watertable at 30 m. Drill to 30 m. RN015583 - Report of limestone <15 m on the driller's and geo's site litho logs was taken to indicate Cambrian. The hard yellow 'clay' above it could be phosphatic. This is above the standing water level. Drill to 36 m. RN005952 - Report of limestone 22-34 m on the drillers log was taken to indicate Cambrian. The yellow 'claystone' above it could be phosphatic. Unfortunately, because this waterbore was drilled into a modern drainage channel, the prospective interval is below the watertable. Step away from the modern drainage and drill to 39 m. Drilling in this area is also 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 has been undertaken in Year 1. The area could be drill tested with only a few holes when funds become available.
