Turquoise Hill Resources is a Canadian mineral exploration and development company headquartered in Vancouver, British Columbia. Its focus is on the pacific rim where it is in the process of developing several large mines, the principal one being the Oyu Tolgoi Project in Southern Mongolia 200 km east of Dalanzadgad. The company was called Ivanhoe Mines until August 2, 2012 when an important financing agreement was made with Rio Tinto.〔(【引用サイトリンク】title=Ivanhoe morphs into Turquoise Hill Resources )〕 In addition to operations that it runs directly (Oyu Tolgoi) Turquoise Hill Resources has a subsidiary in Australia (59% owned Ivanhoe Australia down from 81% in the summer of 2010).〔(【引用サイトリンク】title=ivanhoe mines company profile )〕 SouthGobi is Ivanhoe Mine's coal operations in Mongolia. The Oyuu Tolgoi Project is considered one of the world's largest copper and gold porphyry deposits. For development to happen at Oyuu Tolgoi, an agreement had to be made in which the Mongolian government took a 34% stake in the project; the royalty arrangement it currently has with the Mongolian government took years to reach which caused significant delays in project development.〔 In Australia, Turquoise Hill Resources has stakes in mines containing gold, uranium, copper and the world's highest grade molybdenum and rhenium.〔(【引用サイトリンク】title=mining news )〕 In Mongolia SouthGobi produces coal and controls several other gold and copper mine development projects. It owns a 50% interest in the Kyzyl gold project in Kazhakstan〔(【引用サイトリンク】title=Ivanhoe Mines Announces Commencement to Develop World Class Kyzyl Gold Project )〕 through Altynalmas Gold and has exploration projects in China, Indonesia and the Philippines. Turquise Hill Resources also owns 14% of Entree Gold,〔(【引用サイトリンク】title=entree gold provides exploration update for 2010 )〕 a company with interests in copper and gold projects in southern Mongolia and Arizona, and 14% of Exco Resources which operates Cloncurry's copper project and the White Dam gold mine in Australia. The company's largest shareholder is Rio Tinto which recently increased its stake to 51% which is up from 46.5% beforehand; In June 2011 Rio Tinto paid $502 million for 55 million additional shares, increasing its control to 46.5% from 42% (35% prior to that) and giving it an extra seat on the board (up to 7/14) though Rio Tinto is restricted from increasing its stake in the company to a majority before 2012. Since 2006 Rio Tinto invested $3.5 billion in Ivanhoe Mines.〔 〕 Former Canadian prime minister Jean Chretien is a special advisor to the company.〔(【引用サイトリンク】title=Ivanhoe Mines Ltd.: Altynalmas' Kyzyl Gold Project Estimated Average Annual Gold Production of 368,000 Ounces Confirmed by Independent Pre-Feasibility Study )〕〔(【引用サイトリンク】title=Ivanhoe Mines Ltd. Financial Statements 2009 )〕 In September 2010 it was reported that exploration around Oyu Tolgoi at the Heruga North deposit revealed higher reserves of gold and copper than previously estimated (the news caused IVN share prices to rise 6%).〔(【引用サイトリンク】title=Ivanhoe Mines shares rise after new Mongolian find )〕 Capital spending is likely to reach $5Bn; in October 2010, Ivanhoe announced a new $1Bn share offering in order to raise funds to develop this mine.〔(【引用サイトリンク】accessdate=2010-10-18 )〕 Due to new entitlement offers by Ivanhoe Australia (made to raise funding in order to develop assets in North Queensland, Australia) Ivanhoe Mines' interest in the company was reduced from 81% to 62%.〔(【引用サイトリンク】title=Ivanhoe Australia Seeks Canada Listing )〕 At the end of March 2011 construction of Oyu Toloi was 15% complete.〔 At the end of February 2012 construction of Oyu Tolgoi was 73% complete.〔(【引用サイトリンク】title=Ivanhoe Mines sells stake in coal miner for $889M as it develops Oyu Tolgoi )〕 ==History== 2000 - In December ABM Mining (private) was merged into Ivanhoe Mines. At the time Ivanhoe's main assets included 50% of Myanmar's Monywa Copper Project (28,500 tonnes/year); that year production by both companies totalled 13,350 tonnes for copper, 2 million tonnes for iron ore pellets and 48,000 tones for iron ore concentrate. ABM Mining was founded in 1997 and remained a privately held company until the merger.〔(【引用サイトリンク】title=Ivanhoe Mines' shareholders approve merger with ABM Mining, creating a producer of low-cost copper and iron ore products. )〕 2002 - Subsidiary ABM Mining purchased all of the outstanding debt associated with the Savage River iron ore project in Tasmania, Australia giving ABM Mining a priority claim on the project's assets.〔(【引用サイトリンク】title=Savage River iron ore project debt to be acquired by Ivanhoe Mines subsidiary )〕 2005 - Savage River Project sold to Stemcor Holdings Limited of London for up to US$170 million. The spinoff was part of the company's efforts to shift focus to Oyu Tolgoi (specifically the Hugo deposit).〔(【引用サイトリンク】title=Ivanhoe Mines to Sell Australian Iron Ore Mine to Focus on Development of Mongolian Assets )〕 2007 - In May the company sold all of its coal projects including Ovoot Tolgoi to Asia Gold Corp (currently SouthGobi); as part of the transaction Asia Gold gave Ivanhoe Mines over 80 million more shares of the company raising its interest in it from 45% to a majority stake. Later in October Rio Tinto helped Ivanhoe gain access to a $350 million credit facility which Oyu Tolgoi needed for further development. 2008 - In January Ivanhoe Mines raised $117.9 million through a series of private placements one of which increased its interest in SouthGobi (when it converted preferred shares into common shares). Also that month the newly discovered Heruga Deposit at Oyu Tolgoi was for the first time officially acknowledged (estimates completed) as having a substantial resource of copper, gold and molybdenum. Three months later, in April the government approved the Ovoot Tolgoi project allowing Ivanhoe to begin production in the southern portion (Sunset Field). In May it sold its majority interest in Jinshan Gold Mines for C$216.7 million. Later that summer Ivanhoe's Australian subsidiary went public with a A$125 million IPO (62.5 million shares) and Rio Tinto helped the Oyu Tolgoi project acquire certain equipment. Ivanhoe Australia was floated on the ASX exchange with Ivanhoe Mines owning 80% of it.〔 2009 - Ivanhoe finally reached an agreement with the Mongolian Government on its share in Oyu Tolgoi, taxes as well as Ivanhoe's responsibilities when it comes to the environment and job opportunities for local people. In October Rio Tinto bought 46.3 million common shares for $388 million. In November the China Investment Corporation invested US$500 in SouthGobi in the form of a convertible debenture. 2010 - January - SouthGobi raised C$459 million by going public on the Hong Kong Stock Exchange. In March $250 million of the $500 million China Investment Corporation debenture was converted into SouthGobi common shares; the move lowered Ivanhoe's interest in it to 57%. Also that year, Rio Tinto promised that it will not make any attempts to take over Ivanhoe Mines before October 18, 2011 (Rio Tinto's possible interest in the company is limited to 46.65%).〔(【引用サイトリンク】title=Ivanhoe Mines Ltd Annual Information Form )〕 2012 - April - Ivanhoe Mines sells its 57.6% share of SouthGobi Resources to Chalco for $889 million. The decision came partly as a result of pressure from Ivanhoe's largest shareholder Rio Tinto to sell non core assets.〔 However, the Mongolian government asked that work be stopped at the company's Ovoot Tolgoi mine. On July 31, 2012 Rio Tinto purchased $935 million worth of Ivanhoe shares putting its total interest in the company at 51%.〔(【引用サイトリンク】title=Rio Tinto buys more shares in Ivanhoe Mines )〕 To obtain the additional funding, it was required that Ivanhoe Mines change its name and that founder Robert Friedland resign as CEO.〔 Six of the senior board members also resigned however they didn't include former CEO John Maken who became company president. 2013 – June - Turquoise Hill Resources announced it had secured a $225-million non-revolving bridge facility from majority shareholder Rio Tinto. 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「Turquoise Hill Resources」の詳細全文を読む スポンサード リンク
