The Henty Gold Mine is located at the head of the Henty River on the edge of the West Coast Range in Western Tasmania. It is approximately 30 km north of Queenstown. It is east of Zeehan and south of Tullah. It can be reached by the Hydro-built road that passes between the Henty River and Tullah. ==History== Operations began in the 1990s. Its orebody and viability was ascertained from earlier exploration in the area during the 1970s when the priority was for other forms of mineralization within the Mount Read Volcanic Belt. Henty lies within the mineral rich Mt. Read Volcanic Belt in Western Tasmania that hosts the Hellyer, Que River, Rosebery, Hercules and Mount Lyell base metal deposits. The eastern side of the belt is dominated by the Henty Fault which runs north-east for over 60 kilometres between Mount Charter and Mount Read. The Henty operation is based on a series of structurally complex high-grade zones of gold mineralisation that occur within a package of highly altered volcanic rock adjacent to the Henty Fault.〔http://www.unitymining.com.au/henty-gold-mine-description/ Unity Mining description of the gold mine geological context〕 The Henty Gold Mine was operated by Barrick Gold - currently the largest gold producing company in the world, which acquired the mine through the takeover of Placer Dome in 2006.〔 The Henty mine was expected to close on or before November 2009, with subsequent rehabilitation, due to depletion of ore reserves. Henty Gold was acquired by Bendigo Mining mid-2009. Bendigo specialise in small scale operations and expect to extend the mine's life and also own the Kangaroo Flat Mine at Bendigo.〔(Bendigo Mining website: Henty )〕 The mine continued to operate under Bendigo, producing 43,178 ounces of gold in the 2009-10 financial year, after investing A$3.8 million into mining equipment for the mine.〔(FY10 gold production of 79,827 ounces ) Bendigo Mining website, published: 9 July 2010, accessed: 19 July 2010〕 The Henty Gold Mine has produced about 1.3 million ounces of gold over a 16-year mine life. 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「Henty Gold Mine」の詳細全文を読む スポンサード リンク
