Drilling is under way again at emerging WA nickel stock St George Mining’s (ASX: SGQ) high-grade Mt Alexander project near Leonora. More than 4000m of diamond drilling will test several electromagnetic conductors that suggest an extension of the known high-grade nickel-copper sulphide mineralisation at Mt Alexander. The primary focus of this drilling campaign is the Investigators Prospect.
HIGHLIGHTS:
- Diamond drill programme has resumed at the Mt Alexander Project with more than 4,000 metres of planned drilling at the Investigators Prospect
- Targets include conductors identified by downhole electromagnetic (DHEM) surveys and which are likely to represent massive nickel-copper sulphide mineralisation
- Conductor MAD111: X1 – modelled with an 80 metre down dip extent to the north and conductivity of 140,000 Siemens – is scheduled for drilling later this week
Emerging Western Australian nickel company St George Mining Limited (ASX: SGQ) (“St George” or “the Company”) is pleased to announce that drilling has resumed at the Mt Alexander Project, located near Leonora in the north-eastern Goldfields.
This expanded Phase 2 drill programme follows outstanding results from recent drilling at the Investigators Prospect, which identified significant down plunge extensions of massive sulphide mineralisation and increased the potential of locating further sulphide mineralisation at depth.
More than 4,000 metres of drilling is planned in this programme with initial drill holes designed to test several EM conductors identified from the DHEM surveys in the recently completed drill holes at Investigators.
With an exceptional success rate of testing EM conductors across the Cathedrals Belt, there is very strong potential for these new EM targets to represent further continuity of the known massive nickel-copper sulphide mineralisation.
The first drill hole in the Phase 2 programme will test for an extension of the massive nickel-copper sulphides intersected in drill hole MAD108. The DHEM survey in MAD108 detected a strong EM response towards the west where conductivity/thickness is modelled as 80,200 Siemens.
This may indicate thicker massive sulphides towards the west. The drilling of conductor MAD111: X1 is also scheduled for this week. Newexco has modelled this EM conductor with a conductivity/thickness of 140,000 Siemens and a plunge extent of 80 metres to the north.
This EM target offers an excellent opportunity for a very significant extension to the strike of the known sulphide mineralisation.
John Prineas, St George Mining’s Executive Chairman, said: “We are excited that drilling is again underway at Mt Alexander, with our drilling contractor DDH1 Drilling operating on a 24/7 basis with a double shift.
“Multiple intersections of high-grade nickel-copper-cobalt-PGE mineralisation have been made at Investigators but, with very little drilling below 200m, we have only scratched the surface.
“The initial results from the first deep drilling at Investigators support our geological model that mineralisation continues at depth in the northerly plunge direction.
“This warrants an escalation of the drill programme at Investigators with a range of targets that we believe will expand the footprint of sulphide mineralisation there.”
