St George Mining’s maiden deep drilling at Cathedrals Belt confirms potential for more nickel-copper

Drill hole MAD160 was completed as a deep stratigraphic hole at the Investigators Prospect and intersected a 20-metre thick mafic-ultramafic unit.

St George Mining Ltd (ASX:SGQ) has confirmed further significant drill results from its flagship Mt Alexander Project in the north-eastern Goldfields of WA.

MAD160 is one of the four deep holes completed at the Cathedrals Belt and intersected a 20-metre thick mineralised mafic-ultramafic at 248 metres downhole.

The mineralised interval is 100 metres down-plunge of the closest known high-grade mineralisation – representing a significant extension to the strike of mineralisation down-plunge.

St George executive chairman John Prineas said: “High-grade nickel-copper sulphides at shallow depths have already been identified by drilling at the Investigators, Stricklands, Cathedrals and Radar Prospects.

“The east-west strike of this mineralisation extends for 5.5km on the Cathedrals Belt with another 10.5km of the Cathedrals Belt remaining underexplored and prospective for further deposits of mineralisation.

“The significant east-west strike of high-grade mineralisation along the Cathedrals Belt is indicative of a large mineral system which is also likely to have a significant depth extension.

“It is pleasing to see the results of MAD160 fitting perfectly to this geological model and confirming the continuation of the mineralised ultramafic at depth.

“With limited drilling at depth, the latest drill results are very encouraging for the potential to discover more mineralisation in the north-northwest down-dip direction of the mineralised ultramafic units.”

The mineral system at the Cathedrals Belt is interpreted to be an intrusive system with the mafic-ultramafic intrusions that host nickel-copper sulphides having passed upwards from the Earth’s mantle through major east-west orientated faults located in the northern section of the Cathedrals Belt.

Four deep stratigraphic drill holes have been completed in the current drill program – two at the Investigators Prospect and one each at the Stricklands and Cathedrals Prospects.

All four were designed to test for the continuation of the mineralised ultramafic towards the north and at depth – being down plunge of the high-grade mineralisation already established at these prospects.

All four drill holes intersected the intrusive mafic-ultramafic in positions consistent with the interpreted down-dip extension of those units.

These results are very encouraging and additional deep drill holes will be planned to further test for mineralisation at depth with another deep drill hole at Investigators currently underway.

DHEM surveys will be completed in all four drill holes shortly to investigate for potential mineralisation around the holes and to assist in designing follow-up drill holes.
