Grouped Annual Report GR097/09 EL 24607, EL 29840, EL 29841 and EL 29849 Wonarah Phosphate Project for the period ending 8 January 2016

Abstract

This Combined Annual Report details work completed on EL 24607, EL 29840, EL 29841 and EL 29849 from 9 January 2015 to 8 January 2016. The tenements are held and operated by Minemakers Australia Pty Ltd and together with ML 27244 and EL 23767, form the Wonarah Phosphate Project, with phosphate being the target commodity. The project area lies around a palaeohigh within the Georgina Basin. In 1967 the area was first pegged for phosphate potential by IMC Development Corporation and Minemakers Australia Pty Ltd has held the titles since 2008. Work since 2008 has defined two areas of JORC resources - Main Zone and Arruwurra. The resources lie mostly within ML 27244 but extend onto both EL 29849 and EL 29841. The local geology comprises basement granite of Palaeoproterozoic age, unconformably overlain by basalt of the Helen Springs Volcanics. The volcanics are unconformably overlain by dolomitic rocks of the Thorntonia Limestone equivalent in part. The overlying phosphate-bearing Upper Gum Ridge Formation is divided locally into five units and is overlain by mudstone, siltstone and sandstone of the Wonarah Formation. No work was completed during the reporting year. Exploration work that was scheduled to take place in conjunction with feasibility geotechnical studies on ML 27244 was postponed along with the feasibility study work. Minemakers Australia Pty Ltd is proposing to use the Improved Hard Process ('IHP') to produce super phosphoric acid from rock phosphate mined at the Wonarah deposit and is waiting for commercial validation of the technology. Delays in the validation process, being undertaken at a demonstration plant in Florida, USA, have resulted in postponement of feasibility study activities at Wonarah.
