Gold and base metal explorer, Global Geoscience has commenced drilling at its Brown Mountain base metal project in southern New South Wales, marking the Sydney-based company's maiden drilling program in Australia since listing on the ASX.The target at the Brown Mountain prospect is prospective for volcanogenic massive sulphide mineralisation in the style of the Woodlawn deposit located 180km to the north.A re-interpretation by Global of geophysical and drill hole data collected by previous explorers highlighted the possibility that massive sulphide mineralisation at Brown Mountain may dip towards the west, rather than to the east as previously thought.All previous drilling at the prospect was positioned assuming an easterly dip and Global believes the project is prospective for Woodlawn-style Volcanogenic Massive Sulphide mineralisation. The gossan at Brown Mountain is of similar surface extent to that overlying economic sulphide mineralisation at the Woodlawn deposit, which has a combined total past production and current Resource of approximately 24Mt at 1.7% Cu, 3.8% Pb, 9.5% Zn, 0.5 g/t Au and 80 g/t Ag.The Brown Mountain gossan contains anomalous gold, copper and zinc, as indicated by previous rock chip and drill hole sample data. Copper and zinc are possibly depleted in the oxidised zone and therefore higher economic concentrations are likely to occur in the deeper sulphide zone.The mineralisation at Brown Mountain occurs within a 500m wide, north-south trending belt of sedimentary and volcanic rocks of Silurian-Ordovician age. This belt is bordered to the east and west by granitic rocks of the Devonian Bega batholith."Today represents another milestone in the growth of our company as this is our maiden drilling program in Australia since listing on the ASX late last year," Global Geoscience Managing Director, Bernard Rowe said yesterday.Global Geoscience is drilling a diamond hole from the western side of the gossan to test for a westerly dip to the massive sulphide body. The 300m deep hole will test for primary sulphide mineralisation below where the gossan is at its thickest.
