St George Mining Adds to Mt Alexander EM Conductor Field

THE DRILL SERGEANT: St George Mining (ASX: SGQ) announced location of a new EM target for massive nickel-copper sulphides at the company’s Mt Alexander project, located in the north-eastern Goldfields.

St George Mining reported the EM conductor is modelled with conductivity of 81,000 Siemens, claiming it to be one of the highest of any conductor identified at Mt Alexander to date.

The conductor was observed in the mid to late time data of a recent DHEM survey and recorded a time constant of 100 milliseconds.

The company explained combination of conductivity and time decay of this kind are typical of massive sulphides.

The new EM conductor is coincident with a trend of prominent gravity highs that have been interpreted to represent dense rocks – further confirming the conductor as a compelling target for mineralisation.

Of note, the new conductor is close to several other EM conductors recently identified by the DHEM surveys at West End and Investigators – in drill holes MAD196, MAD199, MAD200 and MAD201.

This field of multiple conductors supports the potential of substantial sulphide mineralisation in this underexplored area of the Cathedrals Belt.

“Our systematic and concurrent use of drilling and downhole EM surveys has delivered another stand-out result with the identification of one of the most exciting EM conductors at Mt Alexander to date,” St George Mining executive chairman John Prineas said in the company’s ASX announcement.

“We have a 100 per cent success rate in confirming conductors of this kind as nickel-copper sulphides, so we are confident that drilling this target will deliver another discovery of high-grade mineralisation.

“The growing number of significant mineralised intercepts and downhole EM conductors at West End and Investigators demonstrates a very large and fertile mineral system and further supports the potential for a significant deposit in this area.”
