THE DRILL SERGEANT: St George Mining (ASX: SGQ) is in the middle of a nickel-copper sulphide drilling campaign at the company’s Mt Alexander project, located near Leonora in the north-eastern Goldfields.
St George Mining has completed numerous drill holes along the Cathedrals Belt that have intersected the host ultramafic unit as well as nickel sulphides, which the company says supports potential for extensions of the known zones of nickel-copper sulphide mineralisation along the Cathedrals Belt.
DHEM surveys are being carried out in the completed drill holes, from which strong off-hole EM conductors have been identified.
Several of these new EM conductors are located down-plunge of known high-grade nickel-copper sulphides, towards the north-northwest that ST George has interpreted to be in a down-dip direction of the host ultramafic unit and identifying it as a priority target area for potential massive sulphides at depth.
To date, 32 drill holes have been completed in the current program and a further 13 drill holes have been planned to test the additional targets identified to date.
He company anticipates adding more drill holes to the program as DHEM survey results are reviewed and further drill targets are prioritised for testing.
“Infill and extensional drilling in the current drill program has successfully increased the continuity of the mineralised horizon at the Cathedrals Belt, where high-grade discoveries at Investigators, Stricklands and Cathedrals have been made over a strike of 4.5 kilometres,” St George Mining executive chairman John Prineas said in the company’s announcement to the Australian Securities Exchange.
““Results at Cathedrals West are particularly pleasing with multiple intersections of ultramafic and nickel sulphide mineralisation extending into the Fairbridge area, where numerous known nickel-copper gossans are located.
“The new conductors identified from the downhole EM surveys are very exciting and have the potential to significantly increase the down-plunge extent of the high-grade nickel-copper sulphides.
“Mineralisation remains open in the down-dip direction to the north-northwest and we will continue to scope out the extent of the mineralisation in this area with deeper drilling.
“The ongoing results from the drilling and downhole EM surveys indicate strong potential for further mineralisation to be discovered at the extensive mineral system at the Mt Alexander project, and we are pleased to extend the current drill program to further test the high-priority targets evolving from the ongoing exploration programs.”
