Where You Will Work
Our Henderson mine and mill are an hour drive apart – separated by the Continental Divide and a 15-mile conveyor system (10 miles underground). The Henderson mine is an underground molybdenum mining operation located approximately 42 miles west of Denver and 10 miles west of Empire. It has been in operation since 1976 and today consists of a large block-cave, underground mining complex feeding a concentrator with a current capacity of approximately 32,000 metric tons per day. It can produce approximately 15 million pounds of molybdenum per year. The Henderson mill is located 15 miles west of the mine, between Dillon and Kremmling.
Both sites are surrounded by US Forest Service land of the Arapaho National Forest, making it easy for our employees and their families to enjoy year-round hiking, cross-country skiing, and snowshoeing in the area. Explore the opportunity to advance your career at one of our sites – the Henderson mine or mill and live life at the top!
