CBH Resources Limited is a significant producer of silver, lead and zinc in Australia. The company operates the Endeavor Mine at Cobar, and is developing the Rasp Mine at Broken Hill. It also owns and operates a concentrate shiploading facility at Newcastle which handles exports of mineral concentrates on behalf of a number of NSW mines.

The Endeavor Mine (Zn-Pb-Ag) is an underground mine that commenced operation in 1983 and was acquired by CBH in 2003. The mine is currently working to an operating plan of 720,000 tonnes per year to produce approximately 40,000 tonnes of zinc metal in concentrate and 25,000 tonnes of lead metal in concentrate.

The Rasp Mine (Zn-Pb-Ag) at Broken Hill received development approval from the NSW government in February this year, and construction commenced in March. CBH has appointed GRES Engineering to manage the development of the project, which is expected to take 13 months to complete at an estimated capital cost of $150 million. Rasp will have a mine life of at least 16 years, and will generate annual revenues of approximately $125 million and employ 160 people when in operation. Annual production is planned to average 34,000 tonnes of zinc metal in concentrate, 28,000 tonnes of lead metal in concentrate, and 1.1 million ounces of silver in the lead concentrate.

The Newcastle Shiploader Facility is centrally located in the Newcastle Port and comprises rail receival, unloading equipment and under cover storage capacity, retrieval and shiploading facilities. In addition to loading Endeavor Mine zinc concentrate, it handles concentrates from other NSW mines and has a throughput capacity of more than 500,000 tonnes per year.

Following a takeover late last year, CBH Resources Limited has become a wholly owned subsidiary of Toho Zinc Co., Ltd, a Japanese company listed on the Tokyo Stock Exchange specializing in nonferrous metals refining.
