Why Is This Rock Worth $400,000?geologyWhat is a magnetite orebody?The orebody is an iron oxide- copper- gold deposit with magnetite being the form of iron ore. In the past, magnetite was traditionally discarded as tailings at the mine site. However new technology in magnetite extraction, now allows it to be captured and sold as a by-product, reducing the amount of tailings sent to the on-site storage facility.Magnetite
