An induced polarization (IP) geophysical survey at Silver City Minerals’ Razorback West project in western New South Wales has identified several chargeability anomalies. The anomalies are coincident with zones of elevated lead and zinc geochemistry and a distinctive elongate gravity anomaly, all of which provide targets for follow-up drilling.

The survey of about 25sqkm was designed to cover an area of elevated lead-zinc geochemistry previously defined by RAB and RC drilling and has highlighted three zones of elevated chargeability – Central, Northeast and East. The Central Zone has particular promise with anomalies which show a strong correlation to the elongate anomaly and the elevated lead and zinc geochemistry.

Razorback West is about 15km northwest of the historic mining centre of Broken Hill and geological interpretation suggests that the host rocks in the area comprise both the Broken Hill and Thackaringa groups. Silver City believes that the anomalies my represent the northern extension to the famous Broken Hill ‘Line of Lode’ corridor offset westward by a fault structure known as the Stephens Creek Shear Zone.

These anomalies are likely associated with base metal sulphides and the IP survey was completed to identify zones of sulphide-bearing rock located in or around potential high-grade silver-lead-zinc mineralization.

Silver City Minerals’ managing director Chris Torrey says, “Our geologists are highly encouraged by the results of the IP survey which has generated a number of quality targets within rock units similar to those which encompass the Broken Hill deposit to the south. The presence of lead and silver-bearing Broken Hill-type lode rocks within the IP anomalies highlights potential for massive sulphide mineralization.”

The company has planned a systematic drilling campaign to fully assess these targets and this is expected to begin in March-April.

Silver City Minerals is a base and precious metal explorer focused on the Broken Hill district in the far west of New South Wales. It takes its name from the famous Silver City of Broken Hill, home of one of the world’s largest accumulations of silver, lead and zinc – the Broken Hill deposit. The company has a portfolio of highly prospective ground with drill-ready targets focused on high grade silver, gold and base metals, and a pipeline of prospects moving toward the drill assessment stage.
