HudBay Minerals is planning to invest $144m in the construction of a new ore concentrator at Lalor zinc-copper-gold project in Manitoba, Canada.
An optimisation study has supported an enhanced production plan, made possible by the construction of a new concentrator and paste backfill plant.
The total estimated cost of the Lalor project, including the new concentrator, is $704m, according to the study.
The new concentrator will have a capacity of 4,500t a day and will be constructed adjacent to the previously planned 985m production shaft.
The firm is planning to start the construction in early 2013 and is scheduled to be completed in late 2014 to coincide with the completion of the production shaft.
