The new geophysical surveys completed at the undrilled Fairbridge Prospect have confirmed several conductive targets that have been prioritised for drilling in the current reverse circulation (RC) drill program.
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 executive chairman John Prineas said: “The drill programme at Mt Alexander is now in full swing with 10 drill holes completed and downhole EM surveys also underway.
“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 – scheduled to commence next week.”
Drilling at West End and Investigators prospects
Six drill holes were completed at the new West End Prospect with all intersecting the western extension of the fault structure that hosts the mineralised ultramafic within the Cathedrals Belt.
Four extensional drill holes were completed at the Investigators Prospect with disseminated nickel-copper sulphides intersected.
Downhole electromagnetic surveys underway
Downhole electromagnetic (DHEM) surveys are being used concurrently with drilling to identify any conductive targets around completed drill holes.
DHEM surveys on completed drill holes at West End commenced yesterday.
Further drilling will be planned for West End and Investigators following a review of the DHEM survey results.
