Fourth annual report for EL 24939 Woolner period ended 10 July 2010

Abstract

During the fourth year of tenure, one diamond drill hole was completed on the floodplains at Woolner station for 164.9m. No mineralisation was encountered. The diamond drill hole was targeting magnetic Palaeoproterozic metasediments on the western flank of the Woolner Dome granite.Only one hole out of the two proposed was drilled due to excessive time spent working out how to drill the first hole and the onset of wet season storms which was starting to limit access. 3D modelling of the magnetic data completed by Matthew Hutchens from AsIs International was used to help define the location, azimuth and dip of the diamond drill hole. The diamond drill hole was drilled via the mud-rotary method until basement was reached at a depth of 68.8m. The first 45m contained wet grey floodplain mud then Cretaceous sand and clay from 45-68.8m. The Woolner floodplain had not been diamond drilled since 1972 and it took drillers H20 Limited from Coolalinga about 7 days to work out how to drill the first 68.8m. The best method to drill the overburden was using a blade bit with large annulus, slow rotation and penetration and very heavy use of mud. Slower drilling worked best so that small pieces of clay could be washed back up the annulus without clogging it and stopping water return. Water carting was a big problem (very slow trips using small trucks) because the floodplain could not handle bigger water trucks and the track was very rough. Once basement was reached, diamond drilling was relatively straight forward. HQ rods with a shoe bit were drilled into basement, then NQ rods were run and diamond drilling commenced. Quarter core was submitted to AMDEL laboratories in Adelaide for assay. Results are not encouraging at all.
