EL 8913, Mount Doreen east, second annual report on exploration for the year ending 31-10-1996

Abstract

79 RAB holes totalling 2933m were completed in the east of the licence along three lines over an area exhibiting magnetic anomalism. In the northern part of the area, a series of wet unconsolidated sand and clay was intersected below the Quaternary gravel. This material made drilling conditions difficult and holes were terminated before intersecting early Proterozoic stratigraphy. The non-magnetic bedrock lithologies intersected are dominated by mica schists, minor gneiss and quartzite. In places swarms of coarse ground quartz-muscovite pegmatite veins intrude these metasediments. Dolomite bodies source some of the magnetic anomalies. Geochemical results were generally disappointing, though minor anomalism to 7. 9ppb Au was encountered.
