Initial underground mine production has successfully commenced at Xstrata Copper’s Ernest Henry Mining operation in north-west Queensland, marking the site’s transition from open pit mining, which is now complete, to underground mining and magnetite processing. This is a major milestone in the progression of Xstrata Copper’s AUD589 million project to extend its Ernest Henry operations to at least 2024.

Xstrata has approved the commencement of an AUD47 million (USD50 million) pre-feasibility study into the development of a large multi-commodity open pit mine on the existing Xstrata Mount Isa Mines footprint. In a joint statement, Xstrata Zinc Australia Chief Operating Officer Brian Hearne and Xstrata Copper North Queensland Chief Operating Officer Steve de Kruijff said the development of a large scale zinc-lead-copper pit has the potential to extend the life of the combined operations to beyond 2060.
