It is operated by African Barrick Gold, who owned 70% of the mine. The remaining 30% was owned by ''MDM Mines''.〔(African Barrick Gold website: Tulawaka Gold Mine ) accessed: 22 July 2010〕 It was one of four gold mines African Barrick Gold, a subsidiary of Barrick Gold, owns in Tanzania, the other three being Bulyanhulu, Buzwagi and North Mara. The mine ceased operation in 2013. ==Description== Gold mining in Tanzania in modern times dates back to the German colonial period, beginning with gold discoveries near Lake Victoria in 1894. The first gold mine in what was then Tanganyika, the Sekenke Mine, began operation in 1909, and gold mining in Tanzania experienced a boom between 1930 and World War II. By 1967, gold production in the country had dropped to insignificance but was revived in the mid-1970s, when the gold price rose once more. In the late 1990s, foreign mining companies started investing in the exploration and development of gold deposits in Tanzania, leading to the opening of a number of new mines.〔(Tanzania Mining History ) tanzaniagold.com, accessed: 24 July 2010〕 The original discovery of the deposit at the Tulawaka mine was in 1998 with Barrick acquiring the project, alongside Buzwagi, as part of its acquisition of Pangea Goldfields Inc. in 2000. African Barrick Gold assumed ownership of the mine in 2010. The Tulawaka mine operated from 2005 through to H1 2013 initially as an open pit operation, subsequently transitioning to an underground mine. Over that time the mine produced nearly 1Moz of gold, nearly double the original feasibility study estimates. The mine is now in the process of being closed which ultimately could involve the removal of all mine infrastructure and the environmental rehabilitation of the area. Discussions with the Tanzanian Government remain ongoing as to the final closure plan. 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「Tulawaka Gold Mine」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
