Thick nickel-copper sulphide intersection confirms down-plunge continuation of Stricklands mineralisation: St George

Thick nickel-copper sulphide intersection confirms down-plunge continuation of Stricklands mineralisation: St George

Growth-focused Western Australian nickel company St George Mining (ASX: SGQ) has announced further strong results at its flagship Mt Alexander Project, located in the north-eastern Goldfields.


HIGHLIGHTS

·       Significant Extension of Mineralisation at the Stricklands Prospect:

·       14m thick zone of nickel-copper sulphides intersected down-plunge at the Stricklands Prospect from 78m downhole in drill hole MARC128

·       The high-grade intersection in MARC128 is 100m down-plunge of the exceptional intersection in MAD71 (17.45m @ 3.01%Ni, 1.31%Cu, 0.13%Co and 1.68g/t total PGEs from 37.45m) and significantly increases the down-plunge strike mineralisation at Stricklands

·       Mineralisation remains open at Stricklands in the north-west direction and at depth

·       Downhole electromagnetic (DHEM) surveys continue to light up strong drill targets:

·       Radar: DHEM survey in MAD152, the discovery hole at the Radar Prospect, indicates that the drill hole intersected the northern portion of the conductor with an extension of the conductor to the south-west

·       Investigators: DHEM surveys in MAD144, MAD145 and MAD147 at the Investigators Prospect identify strong off-hole EM conductors that have been prioritised for immediate drilling

·       Exploration activities in full-swing with two rigs and EM survey crew at site:

·       Reverse circulation (RC) drill rig is at site and is focusing on drilling shallow EM conductors and platform holes for further DHEM surveys

MARC128 at Stricklands 

MARC128 tested an EM conductor at the Stricklands Prospect that is modelled with conductivity of 10,000 Siemens and a strike length of 30m. The conductor is located about 100m north-west of the drill collar for MAD71 that intersected thick, high-grade mineralisation from 37m downhole and returned assays of:

·       17.45m @ 3.01%Ni, 1.31%Cu, 0.13%Co and 1.68g/t total PGEs from 37.45m including the massive sulphide zones of

·       5.3m @ 4.39%Ni, 1.45%Cu, 0.21%Co and 2.09g/t total PGEs from 39.3m and

·       2.02m @ 5.05%Ni, 2.01%Cu, 0.21%Co and 3.31g/t total PGEs from 50.6m and

·       0.5m @ 3.68%Ni, 3.9%Cu, 0.17%Co and 2.68g/t total PGEs from 54.4m

MARC128 was completed by RC drilling to a downhole depth of 166m and intersected nickel-copper sulphide mineralisation between 78m and 92m downhole including intervals of massive and semi-massive nickel-copper sulphides.

The mineralised ultramafic unit at Stricklands is interpreted from drilling to dip towards the north-west with potential for additional sulphide mineralisation at depth. MARC128 has now confirmed the north-west continuation of these ultramafic units containing highgrade nickel-copper sulphides.

The mineralisation remains open to the north-west and at depth. A DHEM survey will be completed in MARC128 to identify extensions of mineralisation around the hole and to plan follow-up drilling.

John Prineas, St George Mining’s Executive Chairman, said: “The mineralised intersection in MARC128 is outstanding as it confirms a significant down-plunge extension of the thick, high-grade mineralisation we first saw at Stricklands in MAD71.

“The thickness of the cumulative ultramafic and the volume of nickel-copper sulphides intersected at Stricklands by multiple drill holes supports the potential of additional significant mineralisation being intersected along this strike of the Cathedrals mineralised trend.

“The down-plunge area is largely untested by drilling and we are increasingly confident that further discoveries of nickel-copper sulphides will be made in this area.”
