Annual Combined Report GR205/11 for EL 25379 Dowling and EL 27363 Jigsaw, Hayes Creek Project for the period 12 January 2012 to 11 January 2013

Abstract

During compilation of data for these titles, it was discovered that 9 drill holes completed in 2010 had not yet been reported to the Department for Mines and Energy NT. These data are included in this report. These holes were part of a 26 hole programme within the Mount Osborne Prospect (falls within EL 23509 and EL 27363) completed in June, July and October 2010. The results from the work were discouraging and it was concluded that the Bella Rose - Mount Osborne trend is characterised by a series of very patchy uranium occurrences within a broad structural corridor. It seems likely that these occurrences are due to localised upgrading of mineralisation at certain elevations due to weathering and water -table movements, rather than the existence of structurally-controlled primary mineralisation. In the period under review, no on-ground works were completed. Office-based work focused on a continuing review of interpretations derived from geological, geophysical and remote-sensing data in previous reporting periods. This has resulted in examination of a magnetically-anomalous body in the nose of a NNE plunging synform which is either a parasitic antiform and/or high-angle reverse fault with associated pyrrhotite alteration (Rankin, 2011). Although lying outside the GR204 title area, the NNE trend apparently extends into EL 25379. Following initial work to verify the existence, nature and prospectivity of the structure in EL 23509, on-ground works will target the feature in EL 25379.
