Annual and final report EL 27027, 3 September 2009 to 11 October 2012

Abstract

Terra Search have reviewed the data sets available for EL27027 and the surrounding area on the basis of aeromagnetics , airborne radiometrics, Google Earth satellite imagery, geology, gravity and water bore drill results. The eastern and southern sections of the tenement is largely underlain by very subdued low relief aeromagnetics indicating thick Cretaceous and Cambrian cover over low magnetic Proterozoic basement. The north western section is underlain by extensive Cambrian basalt. Some magnetic character is evident in the basement but it is very deep. High magnetic basement in the central west of the tenement probably corresponds to basalt flows surrounding Proterozoic basement highs. This is potentially a good environment for phosphate accumulation in a similar fashion to the Wonarah deposit in the Barkly area. However, there is no water bore data nearby to validate this hypothesis, thick cover is likely to make any phosphate accumulation too deep to be economic. Given the lack of encouragement, all of EL 27027 was recommended for relinquishment by Terra Search.
