EL 28045 Gillen Creek Annual Technical Report

Abstract

EL 28045 Gillen Creek located 110km 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 IOCG deposit to the west. Local geology is dominated by protolithic carbonate in the east which transitions abruptly to a pelitepsammite-acid volcanic sequence in the west assigned to the 1810 - 1800Ma Cadney metamorphics ,Aileron Province, Strangways Metamorphic Complex, southeast Arunta Inlier. Johnnies Reward is a mature prospect discovered in 1964 however the last of seven core and 15 RC drillholes were collared in 1987. Several geophysical surveys names GMAG, GEM, SP and IP have been conducted over Johnnies delineating an intense 4000 gamma dipolar magnetic anomaly readily apparent on the regional Alice Springs - Alcoota Regional AMAG dataset. The 2006 GPX HOISTEM/AMAG geophysical survey data captured over Johnnies Reward gossan was acquired modelled and image processed delineating 6 hitherto untested RC drill targets to the north, north northeast and north northwest of the aforementioned JR gossan. A proposed 6 RC drillhole, 1500m program is scheduled for March quarter 2012. Hitherto unpublished GA age dating of a footwall Johnnies Reward gneiss reveals a strong correlation with 1584 Ma coincidently the same age as the giant Olympic Dam IOCGU deposit in South Australia.
