Emerging Western Australian nickel company St George Mining (ASX: SGQ) has announced that a number of new, high priority nickel-copper sulphide targets have been identified at the Mt Alexander Project, located near Leonora in the north-eastern Goldfields. The recent SAM survey has identified a large conductive feature, with an interpreted strike in excess of 300 metres, at the intersection of the Ida Fault and the Cathedrals Belt.
Emerging Western Australian nickel company St George Mining (ASX: SGQ) has announced that a number of new, high priority nickel-copper sulphide targets have been identified at the Mt Alexander Project, located near Leonora in the north-eastern Goldfields.
New geophysical surveys have highlighted a number of conductive features within the Cathedrals Belt that are compelling targets for the extension of nickel-copper sulphide mineralisation including:
· A large conductive area identified adjacent to the intersection of the Ida Fault and Cathedrals Belt, a highly prospective location for the potential concentration of nickelcopper sulphide mineralisation
· Two conductive anomaliesidentified in the northern section of the Investigators Prospect, favourably located down-dip and along strike of known high-grade nickel-copper sulphides
· Two conductive anomalies identified in the underexplored Bullets Prospect, to the east of and along strike of high-grade mineralisation discovered at the Cathedrals Prospect
· New targets are corroborated by data from three separate geophysical surveys – the recent Sub-Audio Magnetics (SAM) survey as well as prior moving loop EM (MLEM), fixed loop EM (FLEM) and fixed loop SAMSON surveys
· Extensive drill programme to commence once Programme of Works is approved
To date, high-grade nickel-copper sulphides have been intersected across a 4.5km strike of the Cathedrals Belt – spanning from the Investigators Prospect in the west to the Cathedrals Prospect in the east. The Cathedrals Belt is inferred to further extend from the western margin of the Investigators Prospect to the Ida Fault approximately 2.5km to the west.
The recent SAM survey has identified 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 that is known to be associated with significant mineral deposits to the north and south of the Mt Alexander Project. This area remains largely undrilled and is referred to as the West End Prospect. This new conductive and structurally important area is 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.
Additionally, four new EM anomalies have been identified coincident with major conductive features proximal 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).
St George Mining Executive Chairman, John Prineas said: “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.
“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.”
