Fourth annual and final surrender report EL 28211, EL 28213 and EL 28214

Abstract

During 2014, a mud rotary (RM) and diamond drilling (DD) program was designed to test conductive features highlighted by the EM survey and additionally for Devonian Sandstone hosted targets. Due to unfavourable results obtained from the first phase of mud rotary drilling, a paired back diamond core program was performed. Areva, in collaboration with the Northern Territory Government's CORE Geophysics and Drilling Collaborations was awarded $100,000 which contributed to two DD holes for a total of 420 m (including 93.5 m of pre-collar RM), drilled during the 2014 campaign. The main findings from the drilling campaign were; No evidence for Tertiary palaeochannel sediments in either Basin and hence no suitable reservoir; Conductive features (EM survey) interpreted as palaeochannels correlate to conductive clays; Highly weathered upper sediments (?Cainozoic); No gamma anomalies; and, Cambrian sequences are not suitable reservoirs. Due to the aforementioned reasons, EL 28211, EL 28213 and EL 28214 were surrendered.
