Annual technical report EL 26898 Katherine-Daly Basin, for the period 14 May 2011 to 13 May 2012

Abstract

EL 26898 was acquired for its potential to host rock phosphate. During the reporting period the following work was carried out: Review of regional radiometric, magnetic, landsat and mineral data; Geological review; Field reconnaissance; 29 in field Niton XRF readings taken from rock outcrops; 12 rock samples submitted to laboratory for multi-element analysis; and Lithological description of 11 rock samples. Lithologies of rock samples collected in the field were described generally as limestone, with samples KN1 to KN5 interpreted as Tindall Limestone and samples and samples KN6 to KN10 and KN13 interpreted as Jinduckin Formation. Rock chips assayed, were on the whole unremarkable with only a few elements raised above background levels. Prime target mineralisation for this tenement was phosphate and only one sample KN1b showing as marginally anomalous returning a 355ppm value for Phosphorus. This same sample was also elevated in Fe (5.33%) as well as marginally anomalous for Pb (146ppm), V(137ppm), W(982ppm) and Zn(105ppm). Stratigraphically this sample represents a fossil-rich nodule layer widely encountered throughout the field area that could be targeted for further investigation. Contingent upon overall project assessment of the phosphate potential of the tenement to be carried out over the coming weeks, activities for the next 12 months might include a comprehensive rock chip sampling and assaying over areas not yet sampled (due to wet access conditions).
