One of the world’s largest known deposits of untapped iron ore is buried inside a great, forested mountain range in the tiny West African republic of Guinea. In the country’s southeast highlands, far from any city or major roads, the Simandou Mountains stretch for seventy miles, looming over the jungle floor like a giant dinosaur spine. Some of the peaks have nicknames that were bestowed by geologists and miners who have worked in the area; one is Iron Maiden, another Metallica. Iron ore is the raw material that, once smelted, becomes steel, and the ore at Simandou is unusually rich, meaning that it can be fed into blast furnaces with minimal processing. During the past decade, as glittering mega-cities rose across China, the global price of iron soared, and investors began seeking new sources of ore. The red earth that dusts the lush vegetation around Simandou and marbles the mountain rock is worth a fortune.
