THE DRILL SERGEANT: Silver City Minerals (ASX: SCI) has commenced drilling at the company’s Copper Blow project, located 20 kilometres to the south of Broken Hill in New South Wales.
Silver City outlined the program, explaining it has been designed to test both magnetic and nonmagnetic targets identified in recent induced polarisation (IP) geophysical surveys.
The company indicated it had received additional encouraging results from a recently completed gradient array induced polarisation survey to the northeast of Copper Blow.
Silver City said earlier drilling encountered intersections of copper, gold and cobalt.
The initial drilling program will comprise two holes, each approximately 450 to 500 metres deep.
One will test for deeper extensions to the copper-gold mineralisation outlined by previous drilling at Copper Blow where mineralisation is hosted in a strongly magnetic ironstone.
The second hole will test a large IP chargeability anomaly located approximately 800 metres to the southeast of Copper Blow.
“The source of this anomaly is unknown but is likely to represent significant sulphide mineralisation,” Silver City Minerals said in its ASX announcement.
“Ground magnetic surveys suggest the rocks in the area of this new IP anomaly are non-magnetic and geological mapping indicates the presence of metamorphosed sediments at surface.
“The 3D IP model however indicates that sulphide-bearing rocks are located more than 100 metres below surface.
“Drilling is designed to test this sulphide zone.”
