Annual Report for ML 27244 Wonarah Mineral Lease for the period ending 18 February 2017

Abstract

ML 27244 forms part of the Wonarah Phosphate Project (along with EL 29840, EL 29841 and EL 29849), and is located approximately 240 km east-southeast of Tennant Creek. Minemakers Australia Pty Ltd is seeking to develop a large sedimentary phosphate deposit within the Georgina Basin. The project area has two principal areas of exploration focus; Main Zone and Arruwurra. The geology of the Main Zone 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 main units; the Transitional Phosphorite, the Transition Sediments, the Chert Breccia Phosphorite, the Mudstone Phosphorite (main phosphate bearing unit) and the Convolute Mudstone. The Wonarah Formation overlies the Upper Gum Ridge Formation and consists of mudstone, siltstone and sandstone. The geology of Arruwurra is essentially similar with some minor differences. The Mineral Resource estimation for both Main Zone and Arruwurra is 842 Mt at 18.1 percent P2O5 (10 percent P2O5 percent cut-off). The resource lies mostly within ML 27244 but extends onto adjacent Minemakers Australia's tenements. Work conducted during the reporting year included rehabilitation of the former camp and minor work on tracks as well as monitoring of rehabilitation to date. Minemakers Australia is proposing to use the Improved Hard Process ('IHP') to produce super phosphoric acid from rock phosphate mined at the Wonarah deposit.
