EL 29840 Arruwurra Partial Relinquishment Report for period ending 18 March 2019

Abstract

EL 29840 (Arruwurra Project) is located approximately 220 km ESE Tennant Creek and approximately 25 km south of the Barkly Highway on the Frew River and Alroy 1: 250,000 and the Joildung and Wonarah 1:100,000 map sheets in the Northern Territory. The tenement was acquired to explore for rock phosphate. The tenement occurs within the central western part of the Georgina Basin where flat-lying, phosphate-bearing Cambrian sediments have been deposited. The lower part of this sequence, the Gum Ridge Formation, is considered prospective for phosphate mineralisation overlying either carbonates or basalts of the Middle Cambrian. The tenement was formed by the amalgamation of several tenements in early 2013. The tenement was reduced by 86 blocks in 2015. A partial cancellation of 37 blocks was made in April 2016. A partial relinquishment of 24 blocks was made in March 2017. This report relates to a further partial relinquishment of 12 blocks, pursuant to section 29 of the Mineral Titles Act, made on 18 March 2019. A total of 4 RC exploration drill holes were drilled on the relinquished part of the tenement, with best results including 1 m at 30.30% P2O5 from 32 metres depth and 1 m at 20.20% P2O5 from 40 metres depth. An additional 12 RC water search holes were drilled on the relinquished part of the tenement. Since 19 March 2013 when EL29840 was granted, work has comprised rehabilitation and rehabilitation monitoring. Although some mineralisation has been identified on the relinquished blocks, it is not considered to be significant compared to the shallow JORC Resource at Arruwurra and Main Zone.
