Tennant Minerals Limited (ASX:TMS) is ready to commenced a new phase of the Stage 3 drilling programme at the Bluebird copper-gold discovery in the Northern Territory which will include testing new priority targets identified across an expanded 1.5km strike-length geophysical footprint.
The new targets have been identified through modelling of IP resistivity data combined with 3D gravity inversions which highlighted the potential to triple the footprint of the copper-gold mineralised zone at the Bluebird discovery.
Previous, strongly copper anomalous shallow RAB drilling, centred 500m to the east of the currently identified mineralisation footprint at “Bluebird East” is associated with recently modelled IP/low-resistivity targets and a thick and continuous gravity “ironstone” anomaly. A similar IP low resistivity/gravity high is located at “Bluebird West”, where no previous drilling has been carried out.
The new phase of drilling at Bluebird will build on further thick, shallow copper-gold intersections which have confirmed the continuity of, close to surface, mineralisation in the newly discovered eastern extension of the Bluebird copper-gold discovery.
The new results from the eastern extension of the Bluebird discovery1 are from within 60m to 80m of surface and indicate potential for shallow open-pit mineable mineralisation.
The Stage 3 drilling programme has to date comprised of 14 holes for 3,166m, with assay results for a further seven holes expected within the next three weeks.
The new drilling phase, comprising up to 4,000m, will aim to define and extend the newly discovered shallow extensions of the Bluebird mineralisation and test the new and highly prospective targets identified at Bluebird East and Bluebird West for repeats of the high-grade copper-gold mineralised deposit.
