Gosse River East - Tennant Creek, NT
(EL 25374 - Truscott 100%)
Gosse River East Project
Truscott's Gosse River East Project extends eastwards from the Ewan Edward project area for a further 22 kilometres, covering predominantly Warramunga basement rocks and intrusive granites. Much of the area is covered by unknown thickness of younger Palaeozoic sediments of the Georgina Basin.
Gosse River East has little previous recorded exploration, and no drilling is known from within the project area. As a result, the thickness of the Georgina Basin sediments is not known but is anticipated to be less than 200 metres. Some limited surface sampling undertaken in 1988 returned weakly anomalous base metal results from cover sediments, but their significance was not recorded.
The project areas was applied for on the basis of geophysical anomalies identified from interpretation of NT Geological Survey aeromagnetics, gravity and geological datasets. Truscott believes that these anomalies reflect conceptual IOCG gold and base metal targets of Tennant Creek style, in the basement Warramunga rocks under a cover of younger sediments. This type of IOCG target and setting is currently being explored with some success by several companies at the Rover Project, a similar distance to the southwest of Tennant Creek. It is also broadly analogous to exploration targeting applied on the Gawler Craton in South Australia.
In addition the review of uranium potential of the Gosse River project, focussing on Cambrian age sediments of the Georgina Basin which are widespread within EL25374, is underway. The Georgina Basin is becoming increasingly recognised as a target for sediment-hosted uranium targets in both NT and Queensland.
Evaluation of aeromagnetic and remote sensing data and GIS compilation of previous exploration results from open file reports is in progress. Several reconnaissance visits to the field area have been carried out, and possible drill access routes across the Gosse River were investigated.
