AusQuest boosted by high-grade discovery

  Diversified exploration company AusQuest has received a significant boost as its 2007 field season draws to a close, announcing yesterday that the first drill hole at its Table Hill Project, located 200km south east of Newman in WA’s Pilbara region, had intersected high-grade manganese mineralisation, which the company has confirmed as the source of a large geophysical anomaly.AusQuest, which controls a large tenement portfolio in the Pilbara region, said the discovery – from the very first drill hole in this previously unexplored region – was a significant development for the company, opening up a new exploration front for 2008.According to the company, assay results received from the first diamond drill hole (THDD01) at Table Hill, designed to test a large geophysical anomaly, confirmed the presence of a 4m-thick manganese-rich layer, with an overall intersection of 3.9m @ 47.5% Mn from 286.8m. The manganese mineralisation is massive in nature, with low levels of phosphorus and iron; however these poor core recoveries may have understated the reported grade.The modelled conductivity-depth sections produced by Fugro Airborne Geophysics for each flight line clearly show a flat-lying zone of high conductivity, which correlates closely to the manganese-rich horizon intersected in THDD01.AusQuest’s Managing Director, Graeme Drew said: “A compilation of these sections suggests that the manganese mineralisation forms a laterally extensive, sheet-like body dipping shallowly to the south at depths ranging from approximately 120m in the north to over 300m in the south.”“A review of the Geotem data in the surrounding area has highlighted at least three additional areas where extensive sheet-like conductors have been outlined, which represent priority drilling targets for additional manganese mineralisation,” he said.In light of the strategic significance of the discovery, AusQuest has moved quickly to submit new tenement applications, covering approximately 5000sqkm, to secure title over these and other areas now believed to be prospective for manganese.
