Annual Report for Barrow Creek EL 28521 for the period 28 October 2011 to 27 October 2012

Abstract

In the first year of tenure, a review of historic exploration over EL 28521 was completed (relevant reports are listed in the bibliography). Although there has been limited work within EL 28521 due to the paucity of outcrop, it appears that a lot of historic work in the greater area has not been captured in the NTGS STRIKE database and some reports associated with the historic work are no longer available. Further work on the historic data and more rigorous compilation of these data are required. Basic reinterpretation of the regional geophysical datasets was also completed. The Total Magnetic Intensity and Bouguer Gravity Anomaly confirm that the geology at Prospect D, Home of Bullion and Kroda extend across EL 28521. Interpretation of the ASTER multi-spectral data provided very little information due to the extensive regolith cover. One reconnaissance field trip was completed to EL 28521. The aim of the field trip was to evaluate access to various parts of the tenement and to develop a cost-effective exploration strategy. Photos showing the surface expression of the tenement are presented in Plate 1. The photographs show sparse hills of predominantly unprospective Central Mount Stuart Formation with flat areas of transported regolith between. Given that the regional magnetic signature is still clear, then this regolith is not considered to be too deep. Where Taylor Creek cuts the tenement, and along strike from Prospect D, no outcrop was identified, although the creek cuts down a few metres. If the regolith throughout the tenement is similar to that seen at Taylor Creek (weakly consolidated colluvial silt and sand), then geophysical prospective should be effective 'see through' it.
