Qualified comments: |
(Applies to: miscellaneous comments) OZ Minerals became owner of this property through the acquisition of Wolfden Resources Ltd in 2007. The three zones are amenable to open pit mining, while the neighbouring Inukshuk zone will be mined underground. This deposit is now owned by MMG Resources Inc. |
