St George Mining begins drilling for nickel-copper at Mt Alexander in WA

The company’s West End and Fairbridge prospects will be targeted for continuations of the high-grade nickel-copper mineralisation.

Mt Alexander Project is emerging as a major new nickel sulphide camp in WA

St George Mining Ltd (ASX:SGQ) has begun drilling nickel-copper sulphide targets at its Mt Alexander project in the north-eastern Goldfields of WA.

The reverse circulation (RC) drilling program comprises 37 holes for more than 5,500 metres of drilling.

Additional holes will be cased in PVC to allow completion of down-hole electromagnetic (DHEM) surveys, which will assist in identifying any sulphide mineralisation around the hole.

“Off to an exciting start”

St George Mining executive chairman John Prineas said: “The 2019 drill campaign at Mt Alexander is off to an exciting start with a range of drill targets that have strong potential to discover further nickel-copper sulphides.

“The RC drill program will be testing for continuations of the known high-grade mineralisation as well as testing for additional occurrences in areas where there has been no or very little previous drilling.

Strong off-hole EM conductors identified

“The first holes to be drilled are at the new West End and Fairbridge targets, located on the highly mineralised Cathedrals Belt and adjacent to the high-grade discoveries at Investigators, Stricklands and Cathedrals.

“The concurrent use of drilling and DHEM surveys will continue to be used to scope out the distribution of the sulphide mineralisation, which proved to be a very effective exploration method with modelling of DHEM data from drill holes completed at Investigators and Stricklands late last year.

“In those holes we identified a number of strong off-hole EM conductors which we believe represent extensions of the known nickel-copper sulphide mineralisation.

“The strong results from the 2018 drilling confirm further high-grade nickel-copper-cobalt-platinum group metals in multiple intersections.

“The high platinum group metals in our mineralisation are particularly pleasing, with palladium currently trading at another new record price and comprising around 80% of the total platinum group metals.”



Drill testing of the areas highlighted below have the potential to significantly increase the scale of the known mineralisation along the Cathedrals Belt:



The Cathedrals Belt extends from the western margin of the Investigators prospect to the Ida fault around 2.5 kilometres to the west.

The West End target incorporate this western extension of the Cathedrals Belt and is interpreted to lie underneath a paleochannel.

Six wide spaced-deep drill holes will be completed at West End in the current RC program and will begin west of Investigators before progressing westwards towards the Ida Fault.

The drilling is also designed to identify zones of disseminated nickel-copper sulphides away from the areas of EM anomalism, which is expanding the footprint of known mineralisation.
