The East Tennant project activity sits within the . It is located east of Tennant Creek and is defined by an approximately northeast-trending corridor extending for 350 km situated between Tennant Creek and the Queensland border. The East Tennant area is almost completely covered by sedimentary rocks of the Georgina Basin, which obscure its potential to host mineral systems. Despite the lack of exposed basement rocks in the area, the East Tennant area was selected as an area for ongoing detailed geoscientific investigation through integration of new multi-disciplinary and multi-scale geoscience data.
The East Tennant region is characterised by a range of geological features that are favourable for mineral systems, including large-scale changes in lithospheric architecture and zones of high electrical conductivity in the crust and mantle. Detailed gravity and broadband magnetotelluric data acquired by the Exploring for the Future Program reveal crustal-scale conductivity pathways that coincide with regional faults.
Stratigraphic drilling was conducted as part of . Ten holes were drilled through a range of cover sequences and into basement for a total of nearly 4,000 m including over 1,500 m of diamond cored basement rocks.
Data from this drilling program will better constrain the East Tennant basement geology and calibrate predictive mineral potential maps to further our understanding of the prospectivity of this promising region. Field data is available for download below and additional data will be progressively added as it becomes available.
