Telfer is a minesite in the Pilbara region of Western Australia, within the Great Sandy Desert. Telfer was previously the state's most isolated town, located north-east of the state capital Perth.〔(【引用サイトリンク】title=Interesting facts about Western Australia )〕 The gold and copper mine is run by Newcrest Mining, and is the second-largest gold mine in Australia. ==History== Newmont Mining first made a claim to the deposit in 1972;〔''The Australian Mines Handbook: 2003-2004 Edition'', page 128, accessed: 27 January 2010〕 however, this is disputed by Jean-Paul Turcaud to this date.〔(The Golden Riddle: Finder's Keepers? ) ABC Radio National, produced by Bronwyn Adcock, broadcast: 6 June 1999, accessed: 27 January 2010〕〔(''The Golden Rule'' ) Book review, author: Bob Sheppard, ISBN 0-85905-311-3, accessed: 27 January 2010〕 The town of Telfer, non-existent until then, was built by Newmont in 1976 and named after A.H. Telfer, a former under secretary for mines in Western Australia. The town grew to a peak of almost 1,000 inhabitants in the early 1990s, with services like a supermarket, a police station, a bank, a community hall, a library and a number of sporting facilities being available.〔''Mining towns of Western Australia'', page: 33-34〕 The mine opened in 1977 as a joint venture between BHP Billiton and Newmont Mining. In 1990, a merger between Newmont Australia Limited and BHP Gold Limited resulted in the creation of Newcrest Mining, with ownership of the Telfer Mine now lying with Newcrest.〔(History of NCM ) Newcrest website, accessed: 27 January 2010〕 Telfer's demographic characteristics were typical of a northern Western Australian mining town. It had a male to female ratio of 2.4 to 1 and almost 40 percent of its population was born overseas. Half its population was below the age of 35 and the town experienced an annual population turnover of almost 20 percent.〔 In 1996, the town suffered the decision to move the Telfer mine from residential to a fly-in fly-out work force. Many of the commercial services were withdrawn, only the recreational facilities were maintained. The existing housing was now used for the accommodation of the mine's mobile work force. One of the main reasons for the town's closure was that fly-in fly-out rosters gave the mine access to a larger skilled work force and to people that would otherwise have been unwilling to relocated to a remote location like Telfer.〔 Open cut mining was suspended in August 2000 due to high operating costs.High production costs were primarily caused by the presence of cyanide soluble copper in the open pit ore.〔 In 2002, Newcrest Mining announced a new redevelopment project worth $1 billion, after discovering new mineral areas and a reserve base of some 19 million troy ounces of gold and of copper. The mine reopened in November 2004, after commissioning of the processing plant and, initially as an open cut mine, from March 2006 also with an underground operation.〔〔(Operations - Telfer ) Newcrest website, accessed: 27 January 2010〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Telfer, Western Australia」の詳細全文を読む スポンサード リンク
