Rover Project EL 25581 Drilling Collaboration Report

Abstract

This collaborative funding application was approved to drill two diamond holes for 1050 metres, in the Rover area southwest of the Tennant Creek Mineral Field. The Rover area has been the subject of exploration targeting for Tennant Creek style Cu-Au-Bi mineralisation since work by Peko in the mid 1970's. Todd River Resources (TRR) has tenure to the immediate southeast of the Rover 1 deposit, ground which last saw exploration activity by Western Desert Resources in 2012. Tenure is now with Todd River Resources Limited's subsidiary Todd River Metals Pty Ltd, and a program has been outlined for early 2019. EL 25581 covers much of the Rover field to the south and east of Rover 1 (Figure 1). Holes drilled through Wiso Basin cover and into the Warramunga Formation, which is the host sequence of both the known Rover mineralisation and all of the Tennant Creek Au-Cu-Bi deposits. This is an area with no surface exposure of the targeted sequence. The package being targeted has 70-200 metres of Wiso Basin cover under thin Tertiary/Quaternary sand cover, and so surface sampling is not effective. All exploration activity to date has been driven by geophysics and then requires drill testing. Geophysical interpretation of the area to date has outlined a complex package of the prospective sequence, with numerous offsetting faults and a number of both mafic and granitic intrusives. Target zones are small discrete magnetic highs, as well as gravity/density high zones with some magnetic signatures but density anomalies can also be targets as some deposits have no magnetite. The existing magnetics and gravity surveys (completed by WDR) were reprocessed in 2018 and targets generated for drill testing. RVDD0001 was drilled to 492.4m and RVDD0002 was drilled to 545.6m. Both holes sufficiently tested the modelled targets and were drilled through Wiso Basin sediments into the Warramunga Formation. Assay results were not exceptional, but follow-up exploration is warranted across the region.
