Additional Information

Description: The Grey River Gold Dredge began operations on the Grey River on the West Coast of New Zealand’s South Island, in early 1989, and worked for approximately eight months before being laid up. The American-based company that moved the dredge from the Taramakau River had modified the operating methods, and then encountered mechanical and financial trouble. The dredge resumed operation in 1992 under the ownership of Birchfield Minerals, Ltd. The Kaniere Gold Dredging Company, Ltd. constructed the dredge, which worked in the Hokitika area from 1938 to 1953, producing 175,000 ounces of gold. In 1957, it was relocated to the Taramakau River, where it worked until 1978, then moved to its present site at Ngahere. About 202,000 ounces of gold were recovered from the Taramakau license. The license area in the Grey Valley covers 375 hectares and, as is normal for all mining licenses of this type, the topsoil is removed before mining begins.
