Resource Development Group Limited provided Sunday Hill Mineral Resource Statement. The Sunday Hill Mineral Resource, reported in accordance with the JORC Code as of the 1st June 2021, is estimated to be 5.0 million tonnes at 18.0 % Mn, 22.8 % Fe and 19.1 % SiO2, using a nominal Mn cut-off of 10%. The Sunday Hill Deposit is located on tenement M46/237, approximately 120 km southeast of Marble Bar and 5 km north of the Ant Hill Deposit. The topology is denoted by a prominent mesa that rises 20-30 metres above the surrounding plain. The following Mineral Resource Estimate was generated by Jason Gotte, who is a full time employee of Mineral Resources Limited. The Resource Estimate was reviewed by Matt Watson who is a full time employee of Mineral Resources Limited. Mr. Watson is acting as the competent person as defined by JORC 2012. Sunday Hill is a fault-bounded, remnant outlier of mid-Proterozoic sediments forming a broad syncline approximately 3 km wide and 4 km long and dipping shallowly to the West. The area contains rocks from the Coondoon (MnC), Hamersley (Hm) and Fortescue (Fj) Formations. A prominent scarp occurs along the North Eastern margins of the deposit, where the Manganese and Hamersley Groups are faulted against Fortescue Group sediments. Massive manganite mineralisation is also hosted within the sub-horizontal mudstones of the Marra Mamba Formation (Hamersley Group) and siliceous cherts of the Pinjan Chert Breccia: a karst-replacement of the Carawine Dolomite. Mineralisation trends NW-SE, dipping to the south-west. The mineralisation has a strike extent of 800 m with down dip extensions of 200 m and thicknesses of 40 m. In 2020, Resource Development Group completed an additional 71 RC holes (4,239m) and 3 Diamond holes (150.4m) with the aim of generating a maiden Mineral Resource Estimate in compliance with JORC 2012. All drilling completed in the 1970s was completed using open hole percussion. All post 1970 drilling was completed using RC face sampling hammers, and PQ3 size core for diamond drilling. Drill spacing is variable across the deposit. In the southern areas, drill spacing is nominally 25 mE x 50 mN while in the Northern areas drilling spacing is wider where the steep nature of the topography has hindered the accessibility of drill rigs. The majority of post 1970 drilling has been orientated at -60 degrees towards 055°, designed to intercept the true width of mineralization. All collars have been snapped to a topographical surface derived from a LIDAR dataset.
