Aus Tin Mining (ASX:ANW) potential expansion at Mt Cobalt


by Rachael Jones

Aus Tin Mining Limited (ASX:ANW) CEO Peter Williams provides an update on drilling at Mt Cobalt with a potential extension of the target zone to the south, and on the company's Taronga and Granville tin projects.

Exploration on Mount Colbalt has seen extensive field reconnaissance in the area over a 10 year period. Only recently an old historic report dated from 1901 was identified which suggested there were further historical workings further south of the target zone. Geologists went in to the field and identified that there was weathered host material for rich cobalt, serpentinite, 190 metres south of the target zone.

Aus Tin Mining (ASX:ANW) also commenced a program of metallurgical test work to assess the potential to pre-concentrate material from the target zone. A series of heavy liquid separation (HLS) tests were conducted to assess the amenability of the target zone mineralisation to gravity separation. Initial results indicate a potential ten-fold concentration of heavy minerals with most of the heavier cobalt-manganese mineralisation expected to report to sinks. Sample fractions have been submitted for geochemical analysis to determine recoveries of cobalt, nickel and manganese.
