EL 27799 Tenement summary report for the period 29 July 2010 to 28 July 2011

Abstract

A study of the geology indicates that conditions have existed for deposition of Mn in a shallow water environment where the anoxic conditions are disturbed during periods of marine transgression and regression. Both Mn oxide and carbonate mineralisation may be possible. A source of marine Mn is in the Palaeoproterozoic to Mesoproterozoic Madderns Yard Metamorphic Complex of the Arunta Block crystalline basement Support for this interpretation is provided by several Mn occurrences clustered within this Formation along strike to the east of EL 27542 (eg: Fenn Gap. The Fenn Gap occurrence, averaging 39% Mn, is sub-vertical and consists of pyrolusite-stained brecciated dolostone. The mineralisation is limited to the surface and appears fault-controlled (Ferenczi, 2001). A number of reported base metal mineralisation occurrences are close to USIs tenements. Further investigation of these occurrences and possible continuation into USI tenements is recommended.
