MAD152 is the first drill hole at the newly named Radar Prospect and intersected nickel-copper sulphide mineralisation between 44.2 metres and 51.7 metres downhole including intervals of massive nickel-copper sulphides.
The hole was drilled to test a new electromagnetic (EM) conductor identified by EM surveys completed by St George earlier this month.
The conductor was initially detected by a Moving Loop EM (MLEM) survey. An optimised follow-up Fixed Loop EM (FLEM) survey confirmed a late-time anomaly, which was modelled with a conductivity of 35,000 Siemens and at a depth of about 50 metres.
A DHEM survey will be completed in MAD152 next week to identify extensions of mineralisation around the hole and to plan follow-up drilling.
The east-west strike of mineralisation on the Cathedrals Belt is now extended to 5.5 kilometres with potential for significant further extensions at the West End Prospect and Fish Hook Prospect, where new EM anomalies have been identified by ongoing EM surveys.

St George Mining executive chairman John Prineas said: “The discovery of high-grade nickel-copper sulphides with the first ever drill hole in an area with about 10 metres of transported overburden and more than 1 kilometre from the nearest known mineralisation on the Cathedrals Belt is an excellent exploration result and a credit to our technical team.
“The occurrence of high-grade nickel and copper sulphide mineralisation at shallow depths is rare and we are delighted to have further extended the strike of this type of mineralisation along the Cathedrals Belt to an impressive 5.5 kilometres.
“With multiple EM conductors still to be drilled, including targets at the unexplored West End and Fish Hook Prospects, we believe there is strong potential for more high-grade nickel-copper sulphide discoveries.”
