Annual Report EL 30090 Southern Cross Bore Project 28 January 2017 to 27 January 2018 Year 3

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. The tenement surrounds EL 28045 also held by Davenport Resourcs Limited which contains the Johnnies Reward prospect, a mature prospect originally discovered in 1964. Very little prior exploration had been done on EL 30090. A review of the 2013 aeromag and VTEM survey on EL 28045 showed the value of the additional detail in interpreting the geology of the region. Consequently, 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. Although the number of samples was small and not all areas were accessible, apart from the previously known copper stained 'Two Amigos' gossan the surface rock samples collected showed only weak and inconsistent anomalous geochemical signatures considered to be associated with metalliferous deposits and in particular IOCG. There is further work to be undertaken on the tenement including follow-up of second order magnetic targets, noting that the 'Two Amigos' gossan has almost no magnetic signature.
