Mining in New Zealand began when the indigenous Māori quarried rock such as argillite in times prior to European colonisation. Mining by Europeans began in the latter half of the 19th century. New Zealand has abundant resources of coal, silver, iron ore, limestone and gold. It ranked 22 in the world in terms of iron ore production and 29th in gold production. The total value of mineral production in New Zealand was $1.5 billion in 2006 (excluding oil and gas). The most important metallic minerals produced are gold (10.62 tonnes), silver (27.2 tonnes) and titanomagnetite ironsand (2.15 million tonnes). A 2008 report estimated that the unexploited resources of just seven core minerals (including gold, copper, iron and molybdenum) totalled around $140 billion in worth.〔 The mining sector makes a significant contribution to the New Zealand economy. In 2004 the value of production from mining (excluding oil and gas) was $1,142 million, or just under 1% of gross domestic product. In 2009 there were 6,800 people employed directly in mining, and 8,000 people, indirectly, flowing from the economic activity of the 6,800. The median wage for a mining employee was $57,320 in 2008, compared to the New Zealand median of $33,530. The latter decades of the 20th century and into the 21st century saw opposition to mining on environmental grounds. The Crown Minerals Act 1991 is a major piece of legislation relating to mining, and a review of Schedule 4 of the Act provoked considerable controversy late in the first decade of the 2000s. ==Coal== Coal mining produced almost 4 million tonnes of coal in 2014, of which 44% was exported.〔 New Zealand coal reserves are in excess of 15 billion tonnes, mainly in Waikato, Taranaki, West Coast, Otago and Southland.〔 Over 80% of the reserves are in Southland lignite deposits worth $100 billion.〔 Coal is produced from four underground and 21 opencast mines.〔(【引用サイトリンク】title=Coal Overview )〕 The largest coal mining company is Solid Energy, a state-owned enterprise. 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「Mining in New Zealand」の詳細全文を読む スポンサード リンク
