Gold miner Evolution Mining has warned of significantly higher costs and lower production at its Mt Carlton mine, in Queensland, after orebodies turned out to be narrower than previously thought.
Evolution on Friday reported that recent grade control and resource definition drilling at the V2 openpit had returned results identifying the West and East lode orebodies were narrowing at shallower levels than previously modelled. A geological review of the underground resource model has resulted in similar geological interpretation as the openpit.
