Reference information

Comments Resource tonnage and grade from Ewers and others (2002); best drill intercept (12.2 m at 0.28% Cu) was in oxide zone; best assays in hypogene zone are about 0.16% Cu with 0.095% Mo (Aussie Q Resources, 2007). Apparently low grade; partly covered by Tertiary basalt and younger sediments (Singer and others, 2008). Fracturing weak to moderate. Lower to middle part exposed. Secondary enrichment very weak.
