Harts Range Garnet Project Annual Technical Group Report for the period 16 October 2015 to 15 October 2016 EL 24360, EL 28696 and EL 30138, GR078/12

Abstract

The Harts Range Spinifex Bore Project tenements EL 24360, EL 28696 and EL 30318 are located along the valley of the Plenty River and cover approximately 335 km2 or 89 blocks. Exploration Licence EL 24378 was surrendered during the year. A garnet resource has been identified and estimated to contain 23.1Mt of sand containing 1.2Mt of garnet in the measured category and 44.5Mt of sand containing 2.65Mt garnet in the Inferred category. The tenements also contain a bore field which can supply process water at a rate of 1,210 m3/day (14 l/s). These are the keystones for project development. A study of the potential water resources in the Harts Range Spinifex Bore Garnet Project area has been undertaken. From previous work three sources need to be examined. Firstly the Ambalindum Sandstone which supplies water to Spinifex Bore and the current project borefield; secondly an aquifer that is likely to be from fractured rock and calcrete that has been identified by aircore drilling and at Benstead Bore; and thirdly a poorly yielding shallow aquifer in the Tertiary sedimentary basin which has been discounted as a potential sustainable aquifer. During the 2015-2016 exploration period Australian Abrasive Minerals Pty Ltd (AAM) have: Undertaken a full review of the water potential in the district; Undertaken a review of tenement with reductions enacted; Completed a deep stratigraphic drilling programme to assess aquifers in the immediate vicinity of the resource and; Successfully commenced construction of the mine at Harts Range. This report outlines the work that has been undertaken.
