St George Mining Ltd (ASX:SGQ) has intersected further nickel-copper sulphide mineralisation at its Investigators prospect within the Mt Alexander Project in Western Australia.

Pre-lab analysis shows that MAD173 intersected 11.2 metres of nickel-copper sulphides from 263.1 metres depth and MAD174 intersected 4.57 metres of nickel-copper sulphides from 223.45 metres depth.

The holes were targeting deeper electromagnetic (EM) conductors identified through downhole EM (DHEM) surveys on nearby drilled holes.

High-grade mineralisation extended by over 300 metres

When compiled with recent drill holes, preliminary results establish a deeper east-west strike of high-grade mineralisation of more than 800 metres.

Positively, the shallow nickel-copper sulphide deposits at Investigators commence 30 metres from surface.

Notably, the latest intersections increase the down-plunge extent of high-grade mineralisation to more than 300 metres.

Investigators one of multiple prospects along Cathedrals Belt

St George’s executive chairman John Prineas said: “These drill results are further evidence of the large high-grade mineral system at the Cathedrals Belt, with significant down-plunge extensions established and mineralisation open in the down-dip direction.

“With only limited drilling at depth, we believe there is strong potential to significantly increase the scale of defined mineralisation, both along strike and at depth.”

DHEM surveys to be completed as drilling continues

A DHEM survey will now be completed in MAD173 and in MAD174 to investigate for further mineralisation around the holes.

Diamond drilling is also continuing with MAD175 now in progress at the Cathedrals Prospect.

The map above of the Mt Alexander tenements shows the key prospects, which are located along the Cathedrals Belt.
