Imagine life today without digital machines, tools, devices and computers. Can’t do it? It’s safe to say that the U.S. is now fully digitally dependent, and semiconductors can’t be made without the rare earths (Scandium, Yttrium, Lanthanum, Cerium, Praseodymium, Neodymium, Promethium, Samarium, Europium, Gadolinium, Terbium, Dysprosium, Holmium, Erbium, Thulium, Ytterbium and Lutetium). Eleven of these minerals, critical ingredients in the production of semiconductors, are found in Mountain Pass, California. Beginning in the 1960s, the mine there was the world’s leading producer of these rare earth minerals.
Expanding the mine would ensure a steady, independent supply of the materials for the U.S. market. Molycorp added Sundt to the list of contractors racing against the clock to bring the mine back online in 2012. We started with a few footing foundations, but because of our mining expertise, great enthusiasm for the challenge, and exceptional work performance, we became a key contractor on this project.
