St George Mining Assays Confirm High-Grade Drill Hits

THE DRILL SERGEANT: St George Mining (ASX: SGQ) announced further thick intercepts of high-grade nickel-copper-cobalt-PGE sulphide mineralisation from Phase 1 of its 2019 drill program at the company’s Mt Alexander project in Western Australia.

St George Mining said it had received assays indicating that drilling had intersected nickel-copper sulphide mineralisation with the best intersections being at the Investigators prospect.

Laboratory assays for hole MARC118 confirmed thick intersections of high-grade nickel-copper-cobalt-PGE mineralisation of:

10 metres at 2.47 per cent nickel, 1.06 per cent copper, 0.07 per cent cobalt and 2.52 grams per tonne PGEs from 142m, including 3m at 3.85 per cent nickel, 2.12 per cent copper, 0.11 per cent cobalt and 4.22g/t PGEs from 145m and 2m at 5.04 per cent nickel, 1.47 per cent copper, 0.16 per cent cobalt and 2.12g/t PGEs from 150m.

St George explained that hole MARC118 was drilled along the north-south MAD60 Line at Investigators, where high-grade nickel-copper sulphide mineralisation had previoulsy been intersected from very shallow depths of 25m below surface and extending down-plunge for a length of more than 380m.

The company said the 10m thick high-grade intercept in MARC118 greatly extends the continuity of mineralisation on the north-south trending MAD60 Line.

High-grade mineralisation was also intersected in hole MARC109, which was drilled approximately 200m to the west-northwest of MARC118.

Assays for MARC109 returned:

4m at 1.21 per cent nickel, 0.47 per cent copper, 0.04 per cent cobalt and 0.99g/t PGEs from 200m, including 2m at 2.04 per cent nickel, 0.83 per cent copper, 0.07 per cent cobalt and 1.67g/t PGEs from 202m.

“The latest high-grade intersections at Investigators establish further continuity to the scope and scale of mineralisation at Investigators,” St George Mining executive chairman John Prineas said in the company’s announcement to the Australian Securities Exchange.

“Ongoing step-out drilling is being planned for Investigators, with two SAMSON EM anomalies in the northern section of the prospect area lined up as high-priority targets for the upcoming drill program.

“The SAMSON anomalies are corroborated by data from two separate geophysical surveys – the recent Sub-Audio Magnetics (SAM) survey as well as a prior moving-loop EM survey, and are compelling drill targets for the discovery of additional mineralisation.”
