St George Mining Ltd (ASX:SGQ) has obtained thick high-grade nickel-copper-cobalt-platinum group element (PGE) sulphide mineralisation in its latest phase-one drilling program at the Mt Alexander Project in WA.
Best intersections were drilled at the Investigators prospect with results establishing further continuity of high-grade mineralisation, both in the northerly down-dip direction and along the east-west trend of the Cathedrals belt.

St George Mining executive chairman John Prineas said: “The latest high-grade intersections at Investigators establish further continuity to the scope and scale of mineralisation at Investigators.
“Ongoing step-out drilling is being planned with two SAMSON electro magnetic (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 are compelling drill targets for the discovery of additional mineralisation.”
Laboratory assays for MARC118 confirm thick intersections of high-grade nickel-copper-cobalt-PGE mineralisation including:
- 10 metres at 2.47% nickel, 1.06% copper, 0.07% cobalt and 2.52 g/t PGEs from 142 metres, including;
- 3 metres at 3.85% nickel, 2.12% copper, 0.11% cobalt and 4.22 g/t PGEs from 154 metres; and
- 2 metres at 5.04% nickel, 1.47% copper, 0.16% cobalt and 2.12 g/t PGEs from 150 metres.
The 10-metre-thick high-grade intersection in MARC118 extends the continuity of mineralisation on the north-south trending MAD60 line.
Other notable intersections were received in MARC109 which drilled about 200 metres to the west-northwest of MARC118, these included:
- 4 metres at 1.21% nickel, 0.47% copper, 0.04% cobalt and 0.99 g/t PGEs from 200 metres, including;
- 2 metres at 2.04% nickel, 0.83% copper, 0.07% cobalt and 1.67 g/t PGEs from 202 metres.
The planning for phase-two of the 2019 drill program at Mt Alexander is being finalised.
The combined diamond and reverse circulation (RC) program will test the new DHEM conductors identified from the phase-one drill holes as well as the northern SAMSON anomalies at Investigators.
A high-powered surface MLEM survey is also scheduled over the West End and Bullets prospects and any EM targets generated by those surveys will be prioritised for drilling in the phase-two drilling program.
