Relinquishment report Part EL 30090 Southern Cross Bore Project (SBX)

Abstract

EL 30090, Southern Cross Bore Project, located about 75kms northeast of Alice Springs is bisected by a north trending zone of intense tectonism called the Pinnacles Shear Zone hosting quartz - copper veins to the east and Johnnies Reward prospect to the west. Local geology is dominated by protolithic carbonate in the east which transitions abruptly to a pelite-psammite-acid volcanic sequence in the west assigned to the 1810 - 1800Ma Cadney metamorphics, Aileron Province, Strangways Metamorphic Complex, southeast Arunta Inlier. In 2017 Davenport undertook a close spaced low level Aeromag survey over the combined area of EL 30090 and EL 28045. The quality of the data was very good over what is a magnetically complex terrane. Southern Geoscience Consultants completed a regional interpretation and highlighted a number of anomalies and priority areas for field checking. A reconnaissance field visit in September 2017 to check the highest priority anomalies and others that were reasonably accessible resulted in a general downgrading of the area. As there were no areas considered to be of interest within the southern area of EL 30090 and the separate part of the EL to the north east of Davenport's EL 20845 it was decided, in accordance with regulatory requirements to relinquish 35 blocks from EL 30090.
