Xstrata Plans Deepening of Its Black Star Open Cut
The project is subject to external and internal approvals. A Mining Plan Amendment detailing plans for the development was submitted to the Queensland government in March 2010. The plan was to be submitted to Xstrata’s executive committee for approval in April.
Xstrata Zinc Australia COO Brian Hearne said, “ With the deepening of Black Star, we can maximize the significant resource potential it contains and maintain the mine’s current production profile. This would enable us to continue to fill the concentrator to its expanded 8 million mt/y capacity.”
Xstrata’s Mt. Isa operations are based on two separate mining and processing streams: copper and zinc-lead-silver. The zinc-lead-silver mining operations include the Black Star and Handlebar Hill open cuts and the George Fisher underground mine.
