The Ni-Cu ores of the Sudbury region were first discovered in 1883. Since then, Sudbury has grown to be the largest and most profitable mining district in North America, with past production plus current inventory, using todays prices, estimated at $400 billion. Sudbury represents the site of a meteorite impact structure originally greater than 200 km in diameter and that formed 1.85 billion years ago. Despite the proven and potential economic benefits of resource development at Sudbury, there are still major outstanding questions concerning our understanding of the structure and its ore deposits, in particular the Copper (Cu)-Nickel (Ni)-Platinum Group Elements (PGE) deposits in the footwall of the Sudbury Igneous Complex.

萨德伯里地区的镍铜矿于1883年首次被发现。从那时起，萨德伯里已发展成为北美最大和最有利可图的矿区，过去的产量加上目前的库存，使用今天的价格，估计为4000亿美元。萨德伯里代表了一个直径最初超过200公里的陨石撞击结构，形成于18.5亿年前。尽管萨德伯里的资源开发已被证明具有潜在的经济效益，但关于我们对该结构及其矿床的理解，特别是萨德伯里火成杂岩下盘的铜（Cu）-镍（Ni）-铂族元素（PGE）矿床，仍然存在重大的悬而未决的问题。
