St George Mining Hits More Copper at Mt Alexander

THE DRILL SERGEANT: St George Mining (ASX: SGQ) claimed discovery of further massive nickel-copper sulphides at the Investigators prospect during a drill program currently underway at the company’s Mt Alexander project in Western Australia.

St George Mining said three of the five drill holes it has completed to date have been successful in testing three separate EM conductors.

MAD43 tested an off-hole DHEM plate at Investigators to a downhole depth of 180 metres, intersecting a 10.2m thick ultramafic unit from 147.8m with nickel-copper sulphides.

The hole also intersected a 9.42m thick interval, from 147.8m, of ultramafic with weak-moderate blebby and disseminated sulphides, plus a 0.73m thick interval, from 157.22m, of massive sulphides with spot XRF readings averaging 5.1 per cent nickel and 2.15 per cent copper.

Hole MAD44 tested another DHEM plate at Investigators, approximately 65m to the west of the DHEM plate tested by MAD43.

MAD44 was also drilled to a downhole depth of 180m, intersecting 8.14m of ultramafic from 147.35m with rare disseminated sulphides, as well as remobilised massive to semi-massive sulphides in granite just below the ultramafic contact from 155.69m to 156.11m.

XRF readings of the massive sulphide shows variation in the nickel content from 5 to 6 per cent nickel in the core to 27 per cent nickel in the coarse grained pentlandite-rich rims.

St George has interpreted the massive sulphides in MAD44 to have been remobilised from a proximal body of nickel/copper sulphide mineralisation.

The company indicated a DHEM survey will be completed in MAD44 to investigate for any conductive bodies around the drill hole that may represent the potential source of the mineralisation.

Drillhole MAD45 tested SAMSON Anomaly 6 at Investigators, intersecting ultramafic from 165.2m downhole.

The sulphide mineralisation intersected was determined to be weak disseminated and blebby sulphides from 171m to 174m, moderate blebby and disseminated sulphides from 174m to 178m, 0.88m of strong disseminated and matrix sulphides from 178m to 178.88m, and 0.2m of massive sulphide from 178.88m to 179.08m with spot XRF readings averaging 4 per cent nickel and 0.1 per cent copper.

Further intersections from MAD45 returned 0.68m of matrix and strong disseminated sulphides from 179.08m to 179.76m, with spot XRF readings averaging 1 per cent nickel and 0.03 per cent copper and 0.37m of massive sulphide from 179.76m to 180.13m, with spot XRF readings averaging 7.9 per cent nickel and 2.9 per cent copper.

“The discovery of further high-grade nickel-copper sulphide mineralisation at Investigators confirms the potential to significantly expand the known mineralisation at this prospect, where mineralisation has already been shown to be present recurrently over a strike length of 1.3 kilometres,” St George Mining executive chairman John Prineas said in the company’s announcement to the Australian Securities Exchange.

“We are very excited by this early success and the potential for more discoveries over the next few weeks.”
