Impact Minerals identifies new Mulga Tank anomaly
THE DRILL SERGEANT: The maiden drill program of Impact Minerals (ASX: IPT) at the company’s Mulga Tank project, located 200 kilometres northeast of Kalgoorlie in Western Australia has caused a bit of excitement.
The drilling is testing a number of EM anomalies within E39/988, and has already identified widespread copper mineralisation around the Mulga Tank Dunite in drill holes at Conductor 1 and Conductor 2.
This has prompted Impact Minerals to review the ionic leach soil geochemistry data over the area.
A large and strongly elevated copper-in-soil anomaly defined by assays above 3000ppb and up to 4,750ppb that covers approximately 8 square kilometres has been identified over the south east quadrant of the Mulga Tank Dunite and also its southern contact with the surrounding rocks.

The anomaly along the southern contact mostly overlies three steeply dipping EM conductors identified by the ground survey and which lie within the dunite.
Impact had previously considered these conductors to be of a lower priority but these have now been upgraded.
The company indicated the elevated copper anomaly to also be coincident with gold and silver-in-soil anomalies.
This area is also partly coincident with anomalous nickel-and palladium-in soil responses associated with Conductor 4.
“This is very encouraging and accordingly the entire southeast part of the Mulga Tank Dunite and immediate surrounding area is now the immediate priority area of interest for Impact,” the company said in its ASX announcement.
“The ionic leach technique is a weak chemical digest designed to detect subtle geochemical responses that may have leaked through transported cover to the surface.
“The discovery of nickel sulphides at depth beneath a nickel-in-soil anomaly at Conductor 1 gives confidence that the technique is working in places over the Mulga Tank Dunite and that the copper-gold-silver responses may indicate a bedrock source.”
Impact is still drilling at Conductor 3 to the immediate northwest of the Mulga Tank Dunite at present and expects to reach its target depth by the end of the week.
The company will then move the rig back to Conductor 1 to test the two conductors identified by the down-hole EM Survey before moving to Conductor 4.
