Silver City Minerals (Silver City) has announced that it has commenced a second round of drilling at Copper Blow located 20 kms south of Broken Hill.

Initially three holes will be completed in order to test extent and continuity of mineralisation down dip and down plunge of existing copper – gold intersections (Phase 1 drill holes).

August and September of 2017 SCI completed approximately 2700 metres of drilling at Copper Blow. The drilling was designed to assess lateral and downdip extensions to a number of high grade copper – gold intersections drilled by BHP and Shell in the late 1980s and early 1990s.

SCI drill holes encountered encouraging copper, gold and cobalt grades hosted in magnetite-rich rocks and confirmed a steep southwest plunge to mineralisation. The best intersection was 4 metres at 6.1% copper, 4.23 g/t Au, 13 g/t Ag and 220 ppm cobalt from 188 metres, including 1 metre at 11.3% copper, 10.7 g/t gold, 25 g/t silver and 405 ppm cobalt from 191 metres in hole 17C B041.

A number of drill intersections contain elevated cobalt with little or no copper – gold hosted in magnetite – pyrite rich rock. For example 5.2 metres at 0.14% cobalt in hole 17CB042 from 400 metres, 2 metres at 0.08% cobalt in hole 17CB049 from 48 metres and 0.75 metres at 0.29% cobalt in hole 17CB043 from 333.6 metres. The magnetite – rich rocks throughout the prospect are elevated in cobalt with surface rock samples returning grades to 0.15%.


The current phase of drilling (850 metres) is likely to take three to four weeks to complete. Initial results of are expected late January to early February 2018. A subsequent, more extensive follow – up program (Phase 2) is planned. It will continue to test down – plunge extensions and conduct preliminary drilling of new geophysical and geochemical targets to the northeast.
