Strategic Energy Resources Limited announced the results of a recent Ultrafine+TM soil geochemistry survey covering the Achilles 1 Prospect at 100% owned South Cobar project (EL9012) in NSW. EL9012 lies along the eastern margin of the Siluro-Devonian Rast Trough at the southern end of the Cobar Basin. The tenement captures the northern and southern extensions of the Woorara fault along strike from Eastern Metals' Brown's Reef polymetallic deposit. The Achilles 1 Prospect lies along the Achilles shear zone, which hosts Australian Gold and Copper's Achilles 2 & 3 Prospects. In preparation for the upcoming drill program to test the Achilles 1 Prospect, a 250-sample soil geochemical survey was conducted over a 4km by 4km area surrounding the Achilles 1 Prospect on a 400m (N-S) by 200m (E-W) grid. The survey was designed to provide a more regional context for the previous closed-spaced soil sampling undertaken by Santa Fe Mining in 1996 and 1997. This past program returned strongly anomalous copper, lead and zinc, and elevated gold, molybdenum and arsenic results coincident with mapped N-S striking
zones of strong silicification but was limited to the Achilles 1 Prospect only. The collected soil samples were analysed for 52 major and trace elements, including gold and base metals, by LabWest Minerals Analysis in Perth using the proprietary Ultrafine+TM methodology developed by the CSIRO. The Ultrafine+TM methodology separates and analyses the <2µm size fraction from the soil. This delivers reduced absolute values when compared to traditional soil geochemistry, but provides a higher signal to noise ratio and reduces the nugget effect for elements such as gold. The result of this methodology is a consistent dataset that is amenable to statistical analysis. SER is a sponsor of the CSIRO-led Ultrafine+TM Next Gen Analytics research project and was therefore able to access CSIRO's latest advanced technologies and research capabilities to assist with the interpretation of the results of the soil survey.
