The company’s 2019 drilling campaign will begin with a reverse circulation (RC) program initially comprising 37 planned drill holes across multiple areas for more than 5,500 metres of drilling.
Downhole electromagnetic (DHEM) surveys will be used concurrently with drilling to identify and investigate sulphide mineralisation.
St George executive chairman John Prineas said the company was pleased to launch its 2019 drill program which would see the first ever drilling at the newly-defined Fairbridge and West End prospects.
“This program will also include our first ever drilling at the Mt Alexander Belt – an underexplored belt with multiple intersections of massive nickel-copper sulphides by previous explorers.
“We believe there is strong potential to discover further nickel-copper sulphides at each of these prospects.”

Fairbridge covers a 1,000-metre east-west strike where high-grade nickel-copper sulphides have already been discovered.
Initial modelling of fixed loop electromagnetic and induced polarisation surveys indicates several anomalies across the strike, providing encouragement the chargeable material may represent sulphide mineralisation.
Prineas continued: “Additionally, the RC program will see a continuation of the resource drill-out at the Investigators prospect where high-grade nickel sulphides have been intersected over a 1.5-kilometre east-west strike and up to 380 metres down-plunge to the north.
“These are all high-quality drill targets with strong potential for significant results that could further enhance the upside at Mt Alexander.”
The West End prospect is a potential 2.5-kilometre extension going west from the Investigators prospect, identified from higher copper values at Cathedral compared to Investigators.
In large sulphide mineral systems, copper values are typically higher in the outer margins of the system and lower near the source of mineralisation, which suggests that Investigators may be closer to the source.
Drilling at the Mt Alexander belt will follow-up historical drilling by BHP which intersected widespread nickel sulphides including massive nickel-copper sulphides.
The intersections were within the priority Sultans prospect and assayed: 2 metres at 2.14% nickel from 64 metres; and 80 centimetres at 2.85% nickel, 0.13% copper and 1 g/t platinum group elements (PGE) from 115.4 metres.
The Mt Alexander Project is 120 kilometres south-southwest of the Agnew-Wiluna belt which hosts numerous world-class nickel deposits.
St George is manager of the project and Western Area’s 25% interest is non-contributing until there is a decision to mine.
