Annual report for EL 9701 Frew River, year ending 09/07/2005

Abstract

Systematic regional geochemical soil sampling was completed over the northern part of EL 9701 in May-June, 2005. A total of 236 samples were collected from 225 sites spaced 500 metres apart on lines also spaced 500 metres apart. An area of approximately 105 square kilometres was covered by the survey. No samples were collected from within exclusion zones around Aboriginal sacred site advised by the Central Land Council Two soil size fractions were collected at each site. A -80# fraction which was subsequently analysed for Cu, Pb, Zn, Co and Ni; and a -2 millimetres fraction which was analysed for low level Au, Pt and Pd. Only a few elevated gold values were obtained. From the 225 sites sampled, 117 sites returned a value above the detection limit of 1 ppb; 12 sites returned a value of 3 ppb or more; the highest value was 8 ppb Au. Results of 3-8 ppb Au are possibly anomalous. Most of these define a coherent zone of elevated gold-in-soil covering an area of about 6 square kilometres. Overall, the 2005 soil sampling program at Frew River has not been successful in defining significant high-level gold anomalism, though infill soil sampling may be warranted in the main area of low-level gold anomalism if ongoing exploration on the Kurinelli goldfield defines economically significant basement gold mineralisation. Peak Pt and Pd values of 4 and 2 ppb respectively were obtained from different samples. These do not appear anomalous. Peak results for base metals were: Cu - 73 ppm - average 21 ppm; Pb - 45 ppm - average 5 ppm; Zn - 63 ppm - average 19 ppm; Ni - 35 ppm - average 35 ppm; Co - 58 ppm - average 9 ppm. These results are consistent with levels obtained at Kurinelli in 2004. None of the base metal results appear anomalous.Systematic regional geochemical soil sampling was completed over the northern part of EL 9701in May-June, 2005.
