There are different methods by which are ranked. One is by their annual production. Another is by their cash cost per ounce, that is, how much money it costs them to mine the gold. Since gold prices are the same everywhere, companies with lower costs per ounce make more profit. The most common method lists by market capitalization which considers the total value of capital holdings by that company. Also considered when comparing companies is their market capitalization per ounce of gold equivalent (sometimes abbreviated MV-GEO, EVO if the enterprise value is used) which takes the market value and total reserves and resources for each company as well as the price of gold into consideration. The figures for each company can be used to determine the value the stock market gives to each company's reserves on an ounce to ounce basis.〔(【引用サイトリンク】title=Digging for Outliers in the Gold Mining Field )〕 If the calculation is to exclude financial assets the enterprise value is used instead of market capitalization.〔(【引用サイトリンク】title=Valuing a Company )〕 EVO = Enterprise Value/Ounce (gold equivalent) = Enterprise Value divided by resources. The enterprise value is the difference between a company's market capitalization (product of the number of company shares and listed stock price) and its cash, investments less debt (amortization). Three of the 10 largest companies by market cap that engage in gold mining, Fresnillo, Buenaventura and Freeport-McMoran (copper/molybdenum) are not included in the first list because they are minor gold producers/most of their revenue comes from a metal other than gold (Fresnillo and Buenaventura rely more on silver, in some lists silver production is treated as gold production, converted to gold equivalent using the gold to silver price ratio; McMoran produced 32.375 tonnes of gold in 2013 (up 32% after falling by 31% in 2012) but gold accounted for only 8% of revenue (down from 10%).〔(【引用サイトリンク】title=Yamana Gold Provides Mercedes Pre-Feasibility and Ernesto/Pau-a-Pique Scoping Study Results and Further Update )〕〔(【引用サイトリンク】title=Freeport-McMoran 2013 Annual Report )〕 World gold production declined by 50 tonnes in 2008 despite a strong showing in market price. Total production cash costs were up 4.1% industrywide in the third quarter of 2010 to US$585 per ounce of gold mined.〔(【引用サイトリンク】title=Gold mine costs up 4.1% in Q3 )〕 The lower price of gold in 2013 is expected to impact gold production in the coming years; Barrick Gold is slowing construction at one of its largest gold projects Pascua Lama (18m ounces of gold, 676m ounces of silver) while in Australia mines are being shuttered by companies in an attempt to curb costs.〔(【引用サイトリンク】title=Barrick To Slow Gold Mine Project )〕〔(【引用サイトリンク】title=Alacer Sees Gold Output Falling In Australia )〕 In 2013, nine of the world's 14 major producing regions recorded growth in output, they are: Australia, Brazil, Canada, Chile, China, Indonesia, Mexico, Papua New Guinea and Russia; In 2012 only Canada, China, Ghana, Mexico, Peru and Russia produced more than the year before.〔(【引用サイトリンク】title=USGS Annual Review )〕 In 2013, the world's five leading gold producers, in order of total production were China (420 tons +17), Australia (250 tons +5), US (227 tons -8), Russia (218 tons +2), South Africa (145 tons -15).〔〔(【引用サイトリンク】title=U.S. Geological Survey, Mineral Commodity Summaries, January 2013 )〕 In 2011, all of the world's 14 major producing countries recorded growth in output except for Peru, Indonesia and Brazil (global primary production up 5.5%); list was led by China (355 tons), Australia (270 tons), USA (237 tons), Russia (200 tons), South Africa (190 tons).〔(【引用サイトリンク】title=Mineral Commodity Summaries 2012 )〕 South Africa's drop in output (down 10% from 2010 to 2012) is not a result of resource depletion but rather high production costs.〔 ==The Big 10== Sources and other information *2008 ranking (Gold Strategist ) *total resource () * 1 tonne = 1000 kg = 2204.6 lbs = 35,273.9619 ounces; 1 ton = 2000 lbs = 32,000 ounces * Newcrest Mining started including Lihir Gold assets in mid-2010 (revenue and profit changes are based on pre merger assets in 2009 and merged assets in 2010). * Metrics such as cash costs, revenue for years prior to 2011 were changed due to the transition in accounting standards from Generally Accepted Accounting Principles (GAAP) to International Financial Reporting Standards.〔(【引用サイトリンク】title=Many Canadian companies plan for bulk of IFRS conversion in 2010 )〕 *For 2012 Barrick Gold's overall losses can be attributed to a $4 billion writedown on copper assets incurred during the final quarter. *Gold Fields production down due to unbundling of certain assets in South Africa into a newly created company called Sibanye Gold.〔 * 3 of the companies took on major writedowns on their assets in the last quarter of 2011 and that affected their annual profits (Newmont $1.6B, Kinross $2.94B, Agnico-Eagle Mines $644.9M). *Newmont operates Australia's two biggest gold mines, Boddington and Kalgoorlie. *On July 25, 2011 Polyus Gold and KazakhGold merged. *In 2013 Goldcorp, Newmont, Newcrest, Kinross, AngloGold, and Eldorado produced more gold than the previous year. In 2012 it was Yamana, Kinross, and Polyus Gold that produced more. In 2011 it was Newmont, Newcrest, Kinross and Eldorado. *November 8, 2012 - Goldcorp (+3.5%) overtakes Barrick Gold (-25%) in market value.〔 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「largest gold companies」の詳細全文を読む スポンサード リンク
