Silver City is focused on its flagship Copper Blow copper, gold and cobalt project around 20 kilometres south of the traditional mining centre in far western New South Wales.
The company also has other precious and base metals prospects around the region.
Induced polarisation (IP) and soil geochemical surveys were recently completed at Copper Blow with the intention of determining drill targets.
The surveys indicate that sulphide mineralisation occurs in a magnetic ironstone horizon, where drilling has been focused, as well as in non-magnetic rocks east and southeast of Copper Blow.
Results indicate a much larger target and potentially much more copper, gold and cobalt, than that solely hosted in the magnetic ironstone complex.
