THE DRILL SERGEANT: St George Mining (ASX: SGQ) is continuing its drilling campaign of nickel-copper sulphide targets at the company’s Mt Alexander project, located near Leonora in the north Eastern Goldfields of Western Australia.
St George Mining has completed new geophysical surveys at the undrilled Fairbridge prospect, which it claims to have confirmed several conductive targets it has now prioritised for drilling in the current reverse circulation (RC) drill program.
The company said the targets have electrical signatures consistent with sulphide mineralisation and the potential to be associated with the surface nickel-copper sulphide gossans observed at Fairbridge and/or the highly mineralised ultramafic units drilled at the adjacent Stricklands and Cathedrals prospects.
St George described the new conductive targets ready for drilling at the Fairbridge prospect as ‘highly-chargeable anomalies’ that have been identified within the 1,000 metre east-west strike of the Fairbridge prospect.
Several of these anomalies are co-incident with nickel-copper sulphide gossans at surface and the company’s interpretation of new geophysical data suggests the mineralised ultramafic units drilled at the Stricklands and Cathedrals prospects continue into the Fairbridge area and extend down-plunge to the north.
Other drilling at the West End and Investigators prospects has confirmed extensions of the Cathedrals Belt.
St George completed six drill holes at the West End prospect, all of which intersected the western extension of the fault structure that hosts the mineralised ultramafic within the Cathedrals Belt.
Four extensional drill holes completed at the Investigators prospect intersected disseminated nickel-copper sulphides.
St George now has Downhole Electromagnetic (DHEM) surveys underway that are running concurrently with drilling to identify any conductive targets around completed drill holes.
The company anticipates further drilling to be planned for West End and Investigators following a review of the DHEM survey results.
“The drill program at Mt Alexander is now in full-swing with 10 drill holes completed and downhole EM surveys also underway,” St George Mining executive chairman John Prineas said in the company’s announcement to the Australian Securities Exchange.
“Initial drill results are encouraging and have identified extensions to the Cathedrals Belt.
“Downhole EM surveys in the completed holes will assist in exploring for further nickel-copper sulphides within the Belt.
“The new conductive targets at the Fairbridge prospect are particularly exciting with final modelling of these targets giving us confidence in the potential of further exploration success in our first ever drilling at Fairbridge.”
