Rosebery

Rosebery is an underground polymetallic base metal mine located in the township of Rosebery, on Tasmania’s west coast, Australia.

 

The mine is approximately 300 kilometres north-west of Hobart and 125 kilometres south of Burnie. It comprises an underground mine and surface processing operation.

Rosebery mine is an important part of the regional economy and social fabric of Tasmania's north-west coast. It has operated continuously since 1936 and currently has a mine life that extends to 2024.

The mine has the capacity to produce approximately 700,000 tonnes of ore a year, which is then processed into zinc concentrate, lead concentrate, and gold and silver doré. It also produces a small amount of copper concentrate.

Zinc is mainly used for galvanising steel against corrosion, while copper is mainly used for electrical wiring and appliances. Lead is mainly used for production of batteries. The ore body extends for approximately 4 kilometres north-south and to a depth of 1.5 kilometres.

The polymetallic nature of the ore body enables a significant relative cost advantage after by-product credits compared to many mining peers.
