EL 28026 Partial relinquishment report sixth year of tenure 23 November 2016

Abstract

EL 28026 'Victoria Highway' is located approximately 100 km southwest of Katherine and approximately 320 km south southeast of Darwin. It covers the nexus of the Daly and Dunmarra Basins and the Kalkarinji Province, all of these being important geological provinces. Modern mineral exploration in the region commenced in the late 1960's and has continued to the present day. Commodities sought have included base metals (copper and lead-zinc-silver), diamonds, phosphate and uranium. AMR completed a detailed airborne magnetic and radiometric survey in late 2013. The data has been interpreted to place a new slant on the mineral potential of the title. Follow up detailed regional stream sediment geochemistry and prospecting of geophysical anomalies has been undertaken over the majority of the area with encouraging initial results that help to corroborate the geophysical interpretations. This suggests that modification of the original models may be warranted, with alternative interpretations of the setting as well as new target concepts that seem to warrant testing. While there is potential for sediment-hosted base metal mineralisation, there are uranium and separate thorium anomalies, the latter apparently in association with discrete magnetic dipoles generated by steeply dipping bodies that are unexpected on current interpretations of the geological setting. There are three target types that are identified from the programme: 1. Steeply dipping magnetic bodies that do not outcrop, but lie beneath topographic highs capped in Cretaceous? sediments that are heavily lateritised and have characteristic Th anomalies. It is speculated that these may be due to carbonatite dykes. 2. Possibly structurally controlled uranium/ base metal/REE mineralisation in sediment breccias near the western margin of the Daly Basin, similar to other anomalies recorded further to the north. 3. Possible base metal deposits in interbedded sediment units in the Antrim Plateau Volcanics on the plains surrounding and to the east of the mesas mentioned in 1. Immediately above. When this report was prepared, some annual reports and appendices were taken for reference, AMR hereby also confirm that we consent to all annual reports containing relevant information on the relinquished area to be released by the government.
