Emerging WA nickel company St George Mining (ASX: SGQ) says it has received further outstanding exploration results at its Mt Alexander project near Leonora. DHEM surveys carried out in the recently completed drill holes at the Investigators Prospect have detected strong conductive responses which are likely to represent further continuity of the massive nickel-copper sulphide system. The most exciting result was from the DHEM survey in MAD111 which detected a strong, off-hole EM anomaly to the west of the drill hole.
· Downhole electromagnetic (DHEM) surveys at Investigators identify multiple EM targets that are likely to represent massive sulphide mineralisation
· Large, off-hole EM conductor identified from DHEM survey in MAD111 modelled with an 80 metre down dip extent to the north and conductivity of 140,000 Siemens
· New DHEM targets are consistent with exploration model of furtherthick massive sulphide mineralisation down plunge to the north at Investigators
· Phase 2 drill programme at Investigators to commence this weekend
Emerging Western Australian nickel company St George Mining Limited (ASX: SGQ) (“St George” or “the Company”) is pleased to announce further outstanding exploration results at the Mt Alexander Project, located near Leonora in the north-eastern Goldfields.
DHEM surveys carried out in the recently completed drill holes at the Investigators Prospect have detected strong conductive responses which are likely to represent further continuity of the massive nickel-copper sulphide system.
The most exciting result was from the DHEM survey in MAD111 which detected a strong, off-hole EM anomaly to the west of the drill hole. Modelling of that anomaly by Newexco indicates an EM conductor – named MAD111: X1 – with a conductivity/thickness of 140,000 Siemens and a plunge extent of 80 metres to the north. The mineralised ultramafic at Investigators dips to the north at an angle of about 30 degrees.
Drilling in the down dip direction continues to intersect high-grade sulphide mineralisation, including on the MAD60 section (approximately 231220E) where the recently completed drill hole MAD108 intersected massive sulphide mineralisation and extended the down plunge strike towards the north to 320 metres – see our ASX Release 23 July 2018 High Grade Nickel-Copper Sulphides in First Drill Hole.
Conductor MAD111: X1 offers outstanding potential for another significant down dip extension of the mineralisation at Investigators.
John Prineas, St George Mining’s Executive Chairman, said: “New conductor MAD111: X1 is arguably the best DHEM conductor we have seen at the Mt Alexander Project.
“The very strong conductivity of 140,000 Siemens isindicative of high grade sulphides, based on our drilling success in this area, and the impressive strike length of 80 metres supports the potential for a very material extension to the strike of the mineralisation.
“The conductor is consistent with our interpretation that the mineral system may increase at depth with thicker sulphide mineralisation. In addition to testing MAD111: X1, we will complete several step out drill holes to the north to further test this exploration model.”
