St George Mining Drills Deeper for Thicker Intercepts

THE DRILL SERGEANT: St George Mining (ASX: SGQ) confirmed further extensions of high-grade mineralisation at the company’s Mt Alexander project, located in the north-eastern Goldfields of Western Australia.

St George Mining completed hole MAD172 to test the first of seven electromagnetic (EM) conductors it has identified so far by downhole EM (DHEM) surveys in recently completed deeper stratigraphic holes along the Cathedrals Belt.

The company said the EM plate targeted by MAD172 is modelled with conductivity of 25,000 Siemens and was predicted to be intersected at 260 metres downhole.

Instead, MAD172 intersected thick nickel-copper sulphides from 242.5m to 259.78m downhole.

The company considers the disseminated and blebby sulphides intersected by MAD172 to be consistent with mineralisation found close to massive sulphide deposits, supporting the potential for more substantial mineralisation nearby.

“Deeper drilling has already confirmed significant down-plunge extensions of the mineralised ultramafic and now – with MAD172 – we have seen the deepest intersection of nickel-copper sulphides at the Cathedrals Belt to date,” St George Mining executive chairman John Prineas said in the company’s announcement to the Australian Securities Exchange.

“The thickness of the mineralised intercept and the style of mineralisation support the potential for further high-grade mineralisation to be present in this area.

“Under the intrusive geological model for the Cathedrals Belt, the larger deposits of mineralisation are likely to be at deeper levels than explored to date, so it is very exciting to see the thickness of nickel-copper sulphides increasing with depth.

“We are increasingly confident that ongoing drilling could discover further significant nickel-copper sulphides down-plunge of the shallow high-grade deposits already established at the Cathedrals Belt.”
