Browns polymetallic ore deposit "sulfide" resources. The oxide resources consist of supergene or weathered sulfide ore where the ore mineralogy is dominated by metal oxides, hydroxides, clays and carbonates after the original sulfide mineralogy. The Browns deposit is currently being developed as a major base metals mine by Compass Resources NL, an Australian public company, in joint venture with Hunan Nonferrous Metals Corporation, a Chinese government company. The mine is due to be complete in August 2008, after suffering cost escalation and construction delays, and will produce 15,000 tonnes of copper, 4,000 tonnes of cobalt and 4,000 tonnes of nickel per annum, with a
Ore Mountains one overarching unit, the Saxon Highlands and Uplands. In addition, its internal divisions were changed. Former major unit 420 was grouped with the western part of major units 421 and 423 to form a new major unit, the Western Ore Mountains ("Westerzgebirge"), the eastern part of major units 421 and 423 became the Central Ore Mountains ("Mittelerzgebirge") and major units 422 and 424 became the Eastern Ore Mountains ("Osterzgebirge"). The current division therefore looks as follows: The geographic unit of the Southern Slopes of the Ore Mountains remains unchanged under the title of Southern Ore Mountains ("Süderzgebirge").
