One of the world's largest nickel deposits, the Sudbury Complex in Ontario, is hosted by 1.85 billion years old igneous rocks. The Huronian sediments, east of the Sudbury Complex, are also enriched in metals and locally, they have elevated concentrations in nickel, copper, gold and cobalt. As the origin of base and precious metals in the sediments have never been identified, a detailed investigation concerning the source of these metals could lead to further discoveries of economic importance in the region.

世界上最大的镍矿床之一，安大略省的萨德伯里复杂矿床，由18.5亿年前的火成岩组成。位于萨德伯里杂岩东部的休伦沉积物也富含金属，在当地，它们的镍、铜、金和钴的浓度都有所升高。由于沉积物中贱金属和贵金属的来源从未查明，对这些金属来源的详细调查可能导致该地区进一步发现具有重要经济意义的金属。
