SummarySummarySummarySummary

ARUF - focus of exploration since the late 1960s; Exploration largely driven by geophysical surveys with airborne radiometrics the key initial discovery tool geophysical surveys with airborne radiometrics the key initial discovery tool

Nabarlek - limited exploration since initial discovery - unsuccessful to date in locating substantial additional mineralisation

Yet – the area has: Extensive structural network and multiple fluid pathwaysWidespread uranium anomalismHost rocksUraniferous granite at depth

Systematic geochemical drilling in the surrounding area has identified a significant number of regolith/bedrock geochemical anomalies associated with structures – in addition to presence of known prospects/deposits (e.g. N147)p p p / p ( g )

Extension of this systematic geochemical exploration to the ML is likely to generate additional drilling targets. Conceptual structural targets have also been identified (“Nabarlek Deeps’)been identified ( Nabarlek Deeps )

Nabarlek is a severely under-explored, high-grade, brownfields exploration project.(Recent Australian uranium discoveries – ‘brownfields’ - 4 Mile 2005; Ranger 3 Deeps 2008)(Recent Australian uranium discoveries brownfields - 4 Mile 2005; Ranger 3 Deeps 2008)
