Octanex Limited announced that a program of geochemical lag sampling has commenced at its Sefton Gold Project in the Eastern Goldfields of Western Australia. This phase of sampling is expected to take approximately three weeks and has the following aims: Collect reconnaissance lag samples over areas that have not previously been sampled by the Octanex field crew. Infill lag sample areas previously identified as gold and copper-gold anomalies to better define them. Octanex is now well into its systematic, wide spaced geochemical lag sampling of the Sefton Project, which is aimed at defining kilometric-scale gold and gold-pathfinder anomalies for follow-up bedrock testing via aircore/RAB drilling. The sampling program is designed to use low-level detection geochemistry to test for anomalies via a staged approach to provide coverage across the project area. Due to widespread transported cover and the deep weathering profile of the region, low values of gold and other `pathfinder' elements in surface material are considered significant and may provide indications of gold in the bedrock. Results from previous sampling by Octanex define coherent zones of gold anomalism, observed in structural corridors defined from regional aeromagnetic images. Octanex's staged geochemical sampling program has identified kilometric-scale gold anomalism at the Sefton Project. Octanex's exploration strategy is to define targets with favourable geochemistry for subsequent bedrock testing (aircore/RAB drilling) in order to define drill targets. Low detection limit geochemistry (identification of coincident multi-element pathfinders and gold) in conjunction with the interpretation of geophysical data are being used to identify mineralised trends.
