New discovery of nickel-copper sulphides
Growth-focused Western Australian nickel company St George Mining Limited has announced a new discovery of high-grade nickel-copper sulphides at its flagship Mt Alexander Project, located in the north-eastern Goldfields.
A 7.5m thick zone of high-grade nickel-copper sulphides has been intersected from 44.2m downhole by drill hole MAD152 - the first hole completed in a new target area of the Cathedrals Belt named the Radar Prospect.
The increased strike of high-grade mineralisation along the Cathedrals Belt is indicative of a large mineral system. This not only increases the potential to discover more mineralisation along the east-west strike of the Belt but also at depth, in the down-dip direction and associated with the structures that are interpreted to be the likely source through which mafic/ultramafic intrusions hosting nickel-copper sulphides have passed upwards from the Earth’s mantle.
John Prineas, St George Mining’s Executive Chairman, said: “The discovery of high-grade nickel-copper sulphides with the first ever drill hole in an area with about 10m of transported overburden and more than 1km from the nearest known mineralisation on the Cathedrals Belt is an excellent exploration result and a credit to our technical team.
“The occurrence of high-grade nickel and copper sulphide mineralisation at shallow depths is rare and we are delighted to have further extended the strike of this type of mineralisation along the Cathedrals Belt to an impressive 5.5km.
“With multiple EM conductors still to be drilled, including targets at the unexplored West End and Fish Hook Prospects, we believe there is strong potential for more high-grade nickel-copper sulphide discoveries.”
