Western Mines Group identifies nickel sulphide at Mulga Tank Project, Western Australia

Mineral exploration company Western Mines Group (ASX:WMG) reports it has identified nickel sulphide mineralisation in a recently completed drillhole at the Mulga Tank Nickel-Copper-PGE (Ni-Cu-PGE) Project in Western Australia.

The company says hole MTD022 was designed to test the centre of the W Conductor MLEM anomaly and follow-up phase one drillhole MTD012 and MTD013, which showed multiple occurrences of visible nickel sulphide veins.

Hole MTD022 and MTD022W1 intersected a thin package of high MgO adcumulate dunite ultramafic around 506m thick, containing disseminated magmatic sulphides that in places coalesced into interstitial blebs (3% to 5% sulphides). 

The sulphide started from around 120m downhole, with multiple broad over 10m zones with pXRF readings of over 0.4% Ni. The company states this is the best indication to date of potential for a relatively shallow Type 2 Mt Keith-style mineralisation.

Western Mines Group Managing Director Caedmon Marriott says: “Step by step… it feels like we’re getting closer as we find out more about Mulga Tank.

MTD022 was the most exciting hole drilled at the project to date for a combination of factors, high MgO adcumulate dunite host rock down the length of the hole, containing disseminated sulphides starting around 120m, broad zones of pXRF readings over 0.4% Ni, highlighting the potential for relatively shallow Mt Keith-style mineralisation.

Then multiple intersections of remobilised high-tenor nickel sulphides towards the end of the hole, at the basal contact of the complex, that could indicate proximity to a Perseverance-style massive sulphide source.

It’s certainly got all the right ingredients and the tea is already thinking about follow-up holes.”

Western Mines reports towards the end of the hole near the basal contact of the complex, 3 intersections of ‘high-tenor’ remobilised massive nickel sulphide was observed and confirmed by spot pXRF readings up to 57% Ni.

These remobilised sulphide intersections were ‘significantly’ larger than those previously seen in holes MTD012 and MTD013. The company states this may indicate closer proximity to a massive sulphide source and hole MTD022W1 was cased for a follow-up downhole electromagnetic survey (DHEM) of this area.

Western Mines reports the drill rig has now moved to the east and has commenced drilling at EIS1. This is the first Exploration Incentive Scheme (EIS) co-funded deep hole.

It is anticipated around 250m to 300m will be drilled before the crew breaks for Christmas and New Year, with drilling expected to recommence in mid-January.

Western Mines Group is a mineral exploration company focused on the exploration and discovery of ‘highly’ prospective projects in Western Australia.

Its flagship project and primary focus is the Mulga Tank Ni-Cu-PGE Project, and other projects held by the company include the Jasper Hill Gold Project, the Melita Gold-Copper-Lead-Zinc Project, the Youanmi Gold Project, and the Pavarotti Nickel-Copper-PGE Project.

The company also holds the Rock of Ages Gold Project, the Broken Hill Bore Gold Project, and the Pinyalling Gold-Copper-Lithium Project.
