Gold and copper exploration undertaken in an 89 square km area of almost no outcrop ( 175 ppm As) were recorded across the drilling traverse from 97WEAR009-018, with a peak assay result of 495 ppm As coming from hole 97WEAR009. The basement lithologies at all three of the latterly drilled prospects comprised biotite gneiss and garnet gneiss with lesser mafic rocks and minor pegmatite. Although the gold results coming from the 1997 drilling were poor, the arsenic anomalism found at Wedgetail was seen to be of interest, particularly since it lies north-easterwards along strike from the Challenger deposit ~17 km to the south-west. No further field work was done on the subject licence area in the succeeding years 4 to 10 of its tenure, but the ground was retained in full due to its possible strategic importance.
