Our ore deposits were the result of at least three different intrusions of magma rich in metals. As the magma cooled, nickel and copper minerals crystallized into a solid ore body. The bottom of the ore body sits roughly 3,000 feet deep and measures to be roughly 6 acres in size. We have two ore types; massive and semi-massive sulfide.
