Impact Minerals receives more good news from Mulga Tank
THE DRILL SERGEANT: Impact Minerals (ASX: IPT) continues to enjoy an early Christmas delivered by results from an on-going maiden drill program being conducted at the company’s Mulga Tank project JV near Kalgoorlie in Western Australia.
The drilling has now identified three mineralised zones, Impact said extend for at least 300 metres of strike along the west side of the Mulga Tank Dunite within E39/988 [Impact 20 per cent and earning 70 per cent from Golden Cross Resources (ASX: GCR)].

The zones have been identified in Hole MTD005, which was drilled by Impact to test Conductor 2, which the company claims can be correlated with similar zones encountered in Hole MTD003 drilled 300m to the south east by a previous explorer.
The company explained the three zones, together with the discovery of nickel-copper sulphides over 150m of strike at Conductor 1 close to the north east part of the Dunite, further confirm the presence of a very large mineralised system associated with the Mulga Tank Dunite announced earlier this month.
“On the west side, two of the zones occur within the Dunite and the third occurs in the immediate footwall to the Dunite,” Impact Minerals said in its ASX announcement.
“Several narrow steeply south dipping veins of high tenor (grade) nickel and copper sulphides occur over several metres within the basal contact zone of the Mulga Tank Dunite in Hole MTD005.
“This zone can be correlated with weak PGE and nickel mineralisation at the base of the dunite in Hole MTD003.”
Impact anticipates this to be the first indication of high tenor mineralisation at the base of the dunite where a massive sulphide deposit may be expected to form.
The veins are sub-parallel to the drill hole, which accordingly was not oriented optimally to intersect them.
In addition the veins have a similar orientation to the high tenor (grade) veins identified three kilometres away in MTD004 at Conductor 1.
A 10m to 15m thick zone of disseminated nickel sulphides occurs about 100m above the base of the Dunite.
Impact has taken readings with a portable XRF analyser on RC chips from Hole MTD005, which returned an intercept of 15m at 0.8 per cent nickel from 80 m depth.
The company considers this zone is able to be correlated with Hole MTD003 where previous assays returned an intercept of 11m at 0.4 per cent nickel, including 1m at 1.1 per cent nickel and 0.5g/t PGE.
The drilling has also identified a zone of weak copper sulphide mineralisation up to 50m thick in the immediate footwall of the dunite.
The copper sulphide (chalcopyrite) occurs as disseminations and in veinlets and fractures.
Assay results from Hole MTD005 are expected in a few weeks.
