Impact Minerals confirms extensive nickel at Mulga Tank

THE DRILL SERGEANT: Impact Minerals (ASX: IPT) has received assays results from the maiden drill program underway at the company’s Mulga Tank project, located 200 kilometres north east of Kalgoorlie.

Impact said the drilling has confirmed the widespread presence of nickel and copper sulphide mineralisation over an area of about 15 square kilometres within and close to the Mulga Tank Dunite within E39/988.

The company has hit nickel and/or copper mineralisation, which it considers warrants immediate follow up work, at four of the six targets tested, while lesser mineralisation was encountered at the other two targets.

Impact has now identified three different styles of high tenor mineralisation at Mulga Tank consisting of:

Extensive disseminated nickel in the Mulga Tank Dunite:

2 metres at 1.3 per cent nickel including 1m at 2 per cent nickel and multiple zones of 0.5m at 0.5 per cent to 1.2 per cent nickel within an intercept of 115m at 0.3 per cent nickel;

Other thick intercepts of 21m at 0.4 per cent nickel and 59m at 0.3 per cent nickel.

High tenor veins at the base of the Mulga Tank Dunite:

0.25m at 3.8 per cent nickel, 0.7per cent copper and 0.7 grams per tonne platinum group elements (PGE) and 0.3m at 0.7 per cent nickel.

High tenor nickel sulphide in multiple komatiites in a flow channel:

0.75m at 0.85 per cent nickel, 0.35 per cent copper and 0.28g/t PGE (platinum+palladium+gold); and

6.7 m at 0.5 per cent nickel.

Impact said it considers the styles of mineralisation and the geology at Mulga Tank to be similar to the Perseverance Dunite near Leinster in Western Australia, which hosts the Perseverance deposit and the nearby Rocky’s Reward deposit.

“A significant amount of new information has been obtained from the six targets tested in this maiden drill program at Mulga Tank,” Impact Minerals said in its ASX announcement.

“This work, together with the results from previous explorers drill holes, demonstrates that the Mulga Tank Dunite contains nickel sulphides in multiple horizons over a very large area of many square kilometres.

“In particular the discovery of high tenor nickel and copper close to the base of the dunite at two locations many kilometres apart is very encouraging.

“The basal contact is highly prospective for the discovery of a massive sulphide deposit over many tens of kilometres of strike both within E39/988 and along strike in other licences within the Mulga Tank project.

“These results are being further reviewed and synthesised in order to determine follow up work program.”
