Silver City Minerals intersects broad copper sulphide mineralisation at Copper Blow

Silver City Minerals Limited announced that significant copper sulphide mineralisation has been intersected in four new diamond drill holes at Copper Blow 20 kilometres south of Broken Hill. Mineralisation is hosted in intense magnetite, quartz and biotite-rich alteration within a shear zone which extends for over four kilometres along strike.

The focus of recent drilling has been the North Zone represented by a magnetic anomaly which is 450 metres long and up to 80 metres wide. It is just one of seven strong magnetic anomalies along the shear zone.

The rock in this zone produces a distinctive induced polarisation geophysical anomaly which is attributed to the presence of abundant copper and iron sulphide hosted with in a magnetite body. Drilling suggests it is particularly enriched in copper sulphide.

In January this year the Company drilled a hole to test the North Zone at depth. Hole 18CB054 returned an intersection of 42.2 metres at 1.3% copper and 0.4 g/t gold in a magnetite-rich rock at a vertical depth of 200 metres. This is considered to be a significant copper-gold intersection.

Hole 18CB054 and several historic RC holes at shallower depths indicated that a broad zone of copper-gold mineralisation extended from surface to at least 200 metres.

Copper Blow is located close to the large mining and infrastructure facilities at Broken Hill.

A follow-up drilling program on the North Zone is ongoing, with four diamond drill holes completed and another two currently under way. In addition RC drilling has been completed in three holes immediately southwest and northeast of the zone. Other targets to the northeast and southwest of the North Zone have been or will be tested as part of this program. To date 11 holes have been completed.
