St George Mining has announced significant results from deep drilling at its flagship Mt Alexander Project, located in the north-eastern Goldfields.

Four deep stratigraphic drill holes have been completed in the current drill programme – 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. 

The latest deep hole to be completed is MAD160 which has intersected a 20m thick mineralised mafic-ultramafic at 248m downhole. 

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

“High-grade nickel-copper sulphides at shallow depths have already been identified by drilling at the Investigators, Stricklands, Cathedrals and Radar Prospects,” St George Mining Executive Chairman John Price said.

“The east-west strike of this mineralization 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.”

The confirmation of intrusive mafic-ultramafic units at depth is very positive for the potential of further nickel-copper sulphides down-plunge from known high-grade mineralsation. 

Additional deep drilling is planned with another deep drill hole at Investigators currently underway.
