Larvotto Resources (ASX:LRV) said initial metallurgical flotation test work on material from the tailings storage facility 1 at its Hillgrove antimony-gold project in New South Wales achieved 80% to 95% recoveries for antimony and 40% to 75% gold recoveries, according to a Thursday Australian bourse filing.

This confirmed that that residual antimony and gold within the around 1.4-million-tonne legacy tailings facility are recoverable using conventional flotation methods, per the filing.

A staged flotation flowsheet was evaluated, comprising selective antimony rougher flotation, and a subsequent gold rougher flotation.
