Silver City Minerals has started diamond drilling at the Balaclava Zinc project south of Broken Hill.

It includes Balaclava, the fault-displaced extension of the Broken Hill mine corridor. Drilling will test rock package hosting zinc sulphides.

SCI and its joint venture partner CBH Resources Limited have been evaluating Balaclava as a possible extension to the Broken Hill mine corridor.

The joint venture has identified a folded rock sequence which hosts zinc-mineralised "lode rocks". Zinc sulphide mineralisation is hosted in five close-space lode horizons in a rock package approximately 150 metres wide.

Drilling is designed to fully test the mineralised package. Work should be completed in two to three weeks.
