Final surrender report for EL 30006 Davis Gap, Ngalia Regional Project, period ending 9 April 2018

Abstract

EL 30006, originally comprising 56 graticular blocks, and located south of the Bigrlyi uranium deposit, was granted on 9th April 2014 for a period of six years. The tenement was acquired to explore for Bigrlyi-style and Camel Flat-style uranium mineralisation hosted within Mt Eclipse Sandstone of the Ngalia Basin and palaeochannel style uranium within Cenozoic cover. Work included a review of historical exploration and the creation of merged regional geophysics imagery from open file and Energy Metals survey data to assist with anomaly targeting. In late 2016, a prospectivity review of EL 30006 was undertaken. It was considered that areas of Mt Eclipse Sandstone were generally located too high up in the stratigraphy to be prospective for Bigrlyi-style uranium deposits. However, the results of the review indicated potential for Camel Flat-style deposits associated with the Yuendumu thrust fault system and palaeochannel-hosted uranium still remained. Surrender of 50 blocks of non-prospective ground was undertaken in March 2017 with two blocks amalgamated with another tenement and four blocks remaining. Following a review of previous drilling results, and a reconnaissance field trip in late 2017, the potential for discovery of a significant Camel Flat-style or palaeochannel-hosted uranium deposit was considered to be low and the tenement was surrendered in its entirety.
