5th Annual exploration report for EL 23698 Helen Springs-Bootu Creek Project, 6 August 2007 to 5 August 2008

Abstract

This title is held for manganese exploration. The exploration licence is located predominately within the Namerinni Group in the Ashburton Province of the Tennant Creek Inlier. The favourable manganese bearing horizon in the adjacent Renner Springs area is hosted principally by the siliciclastic-carbonates of the Shillinglaw Formation (Pms) and is conformably overlain by the Willeray bedded sandstones (Pmw). The prospective Palaeozoic rocks are also covered in part by Cenozoic alluvium, colluvium and aeolian sand. There are no identified manganese outcrops on the exploration licence. During this reporting period, OMM conducted an extensive airborne electromagnetic survey of the Helen Springs and Renner Springs Project Areas. Interpretation of the gridded data shows a large oblate zone of low conductivity surrounded by moderately conductive units. The apparent EM high surrounding the low is most likely an artefact of the first vertical derivative processing of the data as is the EM high which strikes north-south immediately east of EL 23698.
