Sixteenth annual report on the evaluation of AN 366 Emu Fault Zone

Abstract

Authorisation Northern 366 (AN 366) is located southeast of the current McArthur River Mining leases. Under statutory relinquishment regulations AN 366 was previously divided into two separate areas, each focused on an individual area of interest along the Emu Fault Zone. AN 366 North, the Coxco Prospect, is located approximately 10 kilometres southeast of the HYC deposit, and covers an area of 5 graticule blocks (16.45km2). It is a sub-economic carbonate hosted Zn - low Pb deposit within highly prospective Proterozoic McArthur Group stratigraphy, directly adjacent to the major north-south trending Emu Fault zone. The Coxco Prospect contains both stratabound primary mineralisation and stockwork vein hosted secondary mineralisation (Pevely, 2005). Recent work on tenement AN 366 has focused on this northern block of AN 366, including variography, block modelling and resource calculations, as reported in Pevely (2005). AN 366 South, the Amelia Prospect, is located approximately 10km further south from the Coxco Prospect, and covers an area of four graticule blocks (13.16km2). This area was the focus of exploration activities in the early 1990's, but no significant work has been conducted on the area since 1995. The last phase of exploration conducted on the Amelia area suggested further work to be conducted over the tenement, which for various reasons was never completed. Sub - economic base metal mineralisation occurs within the Amelia Prospect, and is hosted in structure controlled vein stockworks, associated with second and third generation structural features (Wilkins, 1991). Due to the loss of Geoscientific staff early in 2008, coupled with the ongoing shortage of exploration geologists throughout 2008, no significant exploration was able to be completed on either AN 366 North or South during the current reporting year.
