在过去20年中,加拿大有126个新矿山投产.统计表明,要维持目前的生产,在下一个20年里,即在2000年以前,尚须新建125个新矿山;如欲保持加拿大对世界市场日益增加的需求量,则新建矿山就应增加到200个,即大约比目前增加67%的产量.五十年代以来,加拿大扩大了找矿范围.发现了昂加瓦的铁矿,育空地区的铅锌矿,不列颠哥伦比亚的铜钼矿,机载物探找到魁北克与安大略的重要铅锌矿,地面物探测出了萨斯喀彻温的许多矿床.许多地质上有利的地区,如魁北克、安大略等,已经过反复探查.在安大略,自1976年以来,没新建过一个矿山.这表明许多地区的找矿勘工
In the past 20 years, 126 new mines in Canada have been put into operation, and statistics show that to maintain current production, 125 new mines will need to be built in the next 20 years, that is, by 2000; if Canada wants to keep Canada on the world market With increasing demand, the number of new mines should increase to 200, or about 67% more than the current output, and Canada has expanded its prospecting range since the 1950s. Iron found in Anguilla, the Yukon Territory Of lead-zinc mine, copper-molybdenum mine in British Columbia, on-board geophysical prospectors found important lead-zinc mines in Quebec and Ontario, and ground-based objects detected many deposits in Saskatchewan. Many geologically-favored regions such as Québec, Ontario Have been repeatedly explored, and in Ontario no new mine has been built since 1976. This shows that prospecting mines in many parts of the country
