Western Mines Group (ASX:WMG) has completed diamond drillhole MTD027 and expanded the mineralisation 4km across its Mulga Tank Project in Western Australia.
The $33.76 million market capitalisation company says hole MTD027 intersected 1,500m of high magnesium oxide (MgO) meso-adcumulate dunite with disseminated nickel sulphide mineralisation and numerous remobilised sulphide veinlets cumulatively over roughly 950m.
This is the sixth hole of the company’s phase two drilling program in the area and lies on the eastern side of the Mulga Tank complex in an area that has seen no previous drilling, according to Western Mines. The hole was designed to test a coincident gravity and magnetic high, a minor moving-loop electromagnetic (MLEM) anomaly, and the presence of nickel sulphide mineralisation in the area.
In addition, hole MTD027 intersected the complex footwall at a deeper depth than originally predicted. Western Mines says this appears to show the eastern margin of the complex is much more steeply dipping and hole MTD020 likely ended in a dolerite sill rather than footwall.
Drilling is continuing to refine the company’s geological model for the complex.
Western Mines Group Managing Director Caedmon Marriott says: “MTD027 was something of a ‘wildcat’ hole out on the eastern margin, in an undrilled area of the Mulga Tank complex. Very encouragingly, nickel sulphide mineralisation was seen down the length of the hole.
“very encouragingly, nickel sulphide mineralisation was seen down the length of the hole.“
Given the visual observations, we were committed to intersecting the basal contact in this area, and the hole went deeper than expected, ending up being the deepest drilled to date. The footprint of the sulphide mineral system has now been demonstrated across the entire 4.5km wide body of the complex from hole MTD022 in the west to this hole MTD027 in the east.
The results of the drilling continue to refine our model of the Mulga Tank Ultramafic Complex and will be extremely valuable when it comes to interpreting the results of our recently completed MobileMT survey at the project.”
Western Mines says this program has been expanded, with continuous drilling anticipated throughout 2023.
Additional drillholes will continue to be added to the program with ongoing targeting work as Western Mines explores the Mulga Tank complex.
Western Mines Group is a mineral explorer focused on the discovery of ‘high-value’ gold and nickel sulphide deposits across a portfolio of ‘highly prospective’ projects located on major mineral belts of Western Australia.
As of 30 June 2023, the company had $3.272 million cash and cash equivalents at hand, according to its latest quarterly report.
