EL 29841 Partial Relinquishment Report for period ending 18 March 2019

Abstract

EL 29841 (Wonarah Project) is located approximately 220 km ESE Tennant Creek and approximately 25 km south of the Barkly Highway on the Alroy 1: 250,000 and the 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. Since 19 March 2013, when EL 29841 was granted, work has comprised rehabilitation and rehabilitation monitoring. A partial relinquishment of what was deemed to be the least prospective part of the tenement was made in March 2015. A partial cancellation of 27 blocks was made 14 April 2016 pursuant to section 105 (1) (b) of the Mineral Titles Act. A partial relinquishment of 27 blocks was made on 20 April 2017, pursuant to section 29 of the Mineral Titles Act. A further relinquishment of 13 blocks took place in March 2019, the subject of this report. A total of 5 RC exploration drill holes were drilled on the relinquished part of the tenement, with best result of 1 m at 20.20% P2O5 from 26 metres depth. An airborne EM survey was carried out to help identify potential aquifers for process water. Since 19 March 2013 when EL 29840 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.
