Rasp Mine

The Rasp Mine is located centrally within the City of Broken Hill and the leases occupy the central region of the historic Broken Hill Line of Lode orebody incorporating the original mine areas that commenced operations in the 1880s.

Underground development activities were suspended in June 2008 with the significant fall in commodity prices and subsequent global financial crisis. Following the takeover of CBH Resources Limited by Toho Zinc Co., Ltd.in  2010, the development of the Rasp Mine became a priority and by January 2011 development approval from the NSW Department of Planning had been obtained.

The project was officially approved by the Toho Board in February 2011 and GR Engineering Services, were engaged for the engineering  design, procurement and construction of the processing plant. Construction commenced in March 2011 and practical completion was achieved on schedule in April 2012. 

The Rasp Mine was officially opened on 25 July 2012 and commercial rates of production are now being achieved. 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. Rasp Mine employs 160 people and will have a mine life in excess of 15 years.
