Afghanistan may hold 60 million tons of copper, 2.2 billion tons of iron ore, 1.4 million tons of rare earth elements such as lanthanum, cerium and neodymium, and lodes of aluminum, gold, silver, zinc, mercury and lithium. For instance, the Khanneshin carbonatite deposit in Afghanistan's Helmand province is valued at $89 billion, full as it is with rare earth elements.
