THE DRILL SERGEANT: St George Mining (ASX: SGQ) declared drilling at the company’s Mt Alexander project in Western Australia encountered further intersections of massive nickel-copper sulphides.
St George Mining commenced the drill program at the Cathedrals prospect where the first hole drilled – MAD65 – tested for an eastern extension of the high-grade nickel-copper-cobalt-PGEs previously intersected at the Cathedrals prospect.
St George said MAD65 intersected massive sulphides where EM modelling had predicted.
The hole was completed to a downhole depth of 95m and intersected a 34.1m thick interval of the Cathedrals ultramafic that included 3.25m of massive, matrix and stringer sulphides from 52.85m downhole.
St George reported average values of the massive sulphide mineralisation, based on portable XRF readings, of 8 per cent nickel and 3 per cent copper.
Hole MAD66 identified further mineralisation in the Cathedrals footwall fault.
This hole was drilled to a downhole depth of 373m and tested an off-hole DHEM plate in the footwall fault, located below the main Cathedrals ultramafic.
St George explained the drill hole will also be used as a platform for a deep search downhole EM (DHEM) survey.
MAD66 also intersected mineralisation where predicted by EM modelling with 5.9m of brecciated massive sulphides and disseminated sulphides from 180.05m downhole.
Spot XRF readings taken by the company for the brecciated massive sulphides ranged from 2 per cent to 11 per cent nickel and up to 1.5 per cent copper.
“This is an excellent start to the drill program with further high-grade mineralisation being identified in both the Cathedrals ultramafic and the footwall fault,” St George Mining executive chairman John Prineas said in the company’s announcement to the Australian Securities Exchange.
“The upcoming drill holes offer more exciting potential with new targets at the mineralised Stricklands and Investigators prospects and also targets in unexplored areas like Anomaly 11 to the south of Cathedrals.”
