Annual report, Warrego North Project, EL 24138, reporting period 8 October 2008 to 7 October 2009

Abstract

In August 2009 a program of geochemical soil and rock chip sampling was carried out to validate the historical geochemistry. A total of 150 samples comprising 5 rock chip (mostly ironstone) and 145 soil samples were collected. The samples were pulverised, put through an aqua regia digest and then analysed for trace level Au by ICP-MS and for As, Bi, Ca, Cu, Fe, and Sb by ICP-AES at ALS Chemex. Results were moderately encouraging when merged with the previous results with gold up to 5 ppb, but most soil samples had below detection levels of gold. The rock chip samples had disappointing Au results, but had elevated levels of Bi and Cu commonly coincident with the elevated Au values. Figures 8 to 10 show the Cu, Bi and Fe values for the samples collected in this reporting year plotted with samples from previous sampling.
