Grouped Annual Report GR097 EL 29840, EL 29841, EL 29849 and EL 31477 Wonarah Phosphate Project for the period ending 8 January 2019

Abstract

This Combined Annual Report details work completed on EL 29840, EL 29841, EL 29849 and EL 31477 from 9 January 2018 to 8 January 2019. The tenements are held and operated by Minemakers Australia Pty Ltd and 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 EL 31477 but extend onto EL 29840, EL 29841 and EL 29849. 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. Proposed work for the reporting year of environmental monitoring, weed control and general tidying up did not take place due to unavailability of key personnel at the time the work was scheduled.
