THE DRILL SERGEANT: St George Mining (ASX: SGQ) informed the market it has identified new, high-priority nickel-copper sulphide targets at the company’s Mt Alexander project, located near Leonora in the north-eastern Goldfields.
St George has previously reported intersections of high-grade nickel-copper sulphides across a 4.5-kilometre strike of the Cathedrals Belt – spanning from the Investigators prospect in the west to the Cathedrals prospect in the east.
Work completed by St George has inferred the Cathedrals Belt extends from the western margin of the Investigators prospect to the Ida Fault approximately 2.5km to the west.
The company recently carried out a SAM survey, identifying a large conductive feature, with an interpreted strike in excess of 300 metres, at the intersection of the Ida Fault and the Cathedrals Belt.
The Ida Fault is a deep, tectonic fault known to be associated with mineral deposits to the north and south of the Mt Alexander project.
This area remains largely undrilled and is referred to by St George as the West End prospect.
The company considers this new conductive and structurally important area to be a high-priority target for the discovery of nickel-copper sulphides and will be the first target to be drilled when drilling re-commences at Mt Alexander shortly.
An additional four new EM anomalies have been identified coincident with major conductive features close to known nickel-copper sulphides at both the Investigators prospect (a 1.5km east-west striking ultramafic dipping at 30 degrees to the north) and at the underexplored Bullets prospect (east of the Cathedrals prospect).
“The new target areas are located along strike or down-dip of high-grade nickel-copper sulphide mineralisation already discovered at the highly mineralised Cathedrals Belt, and are supported by three separate geophysical surveys,” St George Mining executive chairman John Prineas said in the company’s announcement to the Australian Securities Exchange.
“The new conductive target adjacent to the Ida Fault is particularly exciting.
“This area has never been drilled and we look forward to drilling this large target soon.
“We are also very enthusiastic about the new conductive anomalies to the north of Investigators as our geological model for the Cathedrals Belt supports the scope for continuity of high-grade mineralisation either at depth in the northerly down-dip direction or through the repetition of the mineralised ultramafic in the north.
“These are compelling targets for the potential discovery of further nickel-copper sulphides which could significantly expand the footprint of high-grade mineralisation at Mt Alexander.”
St George Mining said the drilling of these new anomalies will represent a major step-out for the company from the large mineralised horizon it has already established at Investigators and will test for extensions of the known high-grade mineralisation.
