U.S. Energy (USE) has put its energy in many places, including oil and gas exploration and production, geothermal energy projects, and molybdenum mining. It operates oil and gas wells on the coast of the Gulf of Mexico and in Texas. The company bought a quarter stake in Standard Steam Trust in 2008, giving USE entry into the geothermal energy market. It also is developing a molybdenum mining project in Colorado. U.S. Energy has an agreement with Thompson Creek Metals to fund development of the project. The company had owned almost half of Sutter Gold Mining but sold most of its stake in the gold miner in 2008.
