The Thompson Creek Mine, near Challis, Idaho, is one of the four largest open pit, primary molybdenum mines in the world.

Thompson Creek Mining Company has an enviable record of environmental excellence,and has received numerous awards, including:
- BLM Hardrock Mineral and Community
- Outreach and Economic Security Award
- Idaho Department of Lands
- Excellence in Annual Operations

Located in the rugged mountainous terrain of east-central Idaho at elevations ranging from 6,000 to 8,500 feet above sea level, Thompson Creek Mine is 35 miles southwest of
Challis in Idaho’s Custer County. It is situated on a combination of private and federal lands, partially within the Challis National Forest. Primary access to the mine is by improved county and private roads. The mine property covers 2,500 acres and includes an open pit, mill and tailings facility.

Thompson Creek Metals Company is one of the world’s top molybdenum producers. Thompson Creek Mining Company (TCMC) is a wholly-owned subsidiary of Thompson Creek Metals Company.

Thompson Creek Metals Company operations include the Thompson Creek Mine in Idaho, the Langeloth conversion plant in Pennsylvania, and the Endako Mine and the
Davidson project, both in British Columbia.

Custer County’s Largest Employer is a Major Contributor to Idaho’s Economy - A success story for Idaho exports, molybdenum from Thompson Creek Mine is sold around the world to steel and other manufacturers. The mine has a workforce of 350 employees, resulting in an annual payroll and benefits totaling $28 million. In addition, the mine spends between $70 and $80 million per year on goods and services.

Thompson Creek also plays an important global role. The mine’s annual production of 15 to 20 million pounds of molybdenum represents 6% of the world supply. Our employees contribute to the community and the company donates more than $195,000 a year throughout southeast Idaho.

Molybdenum the “modern metal” makes the products we use stronger, safer, longer lasting and more energy efficient. Thompson Creek Mine is a world-class ore deposit with over 215 million pounds of molybdenum. The high quality Thompson Creek “moly” is an essential resource that is used in worldwide markets for a wide variety of applications, including stainless steel, construction steel, petroleum catalysts, high-speed tool steels and lubricants.

Molybdenum is…
_ An alloying agent to enhance the strength, toughness and corrosion resistance of steel
_ A key component in steels used in oil and gas exploration and pipelines
_ A crucial ingredient in steels used in building exteriors and in high-temperature applications, such as jet engines and turbines and in gas, coal and nuclear power plants
_ A key ingredient in catalysts employed by petroleum refineries to reduce sulfur in gasoline and diesel
_ A growing ingredient in various steel-consuming industries for better strength-to-weight ratios to enhance crash-safety ratings and reduce weight
_ A lubricant in high-performance synthetic motor oil

The Community Partner - Like the material it produces, Thompson Creek Mine epitomizes the modern mining operation. It is owned and operated by people with long experience in the mining industry. Since our employees live here and raise their families here they value the landscape, the environment and the many recreational opportunities the area offers. They are first and foremost community members. The company is committed to the project and the community and to the health and safety of its employees.

We support the community’s infrastructure and programs with monetary assistance and manpower, and we match employee donations to community causes, such as:
_ Scholarships & Partners In Education
_ Chamber of Commerce Information Center
_ Custer County Watershed Advisory Group
_ Challis Experimental Stewardship Project
_ Emergency Response Coordination
_ Land of the Yankee Fork Interpretive Center
_ Charitable, Youth, Sporting, Parks, Schools, Veterans, and Numerous other Community Organizations

Commitment to Reclamation - Thompson Creek Mining Company’s honored environmental commitment has set an example for mining operations throughout the world. Innovative reclamation practices include:
_ Final reclamation is implemented as soon as possible.
_ Interim reclamation is implemented on all areas of the mine.
_ The operation is a zero discharge tailings facility. All water on and off site is controlled and managed.
_ Final reclamation focuses on multiple use and wildlife habitat.
_ Innovative practices using confined animal feeding operations and high altitude pine tree seed stock have proven effective.

History of Operation - Central Idaho has a long history of human exploration. Fur traders were active in the area as early as 1824, followed by prospectors and miners in the 1860s and 1870s. Custer County was established January 8, 1881, and was named for one of the area’s historic gold mines, the General Custer Mine. The county covers an area of nearly 5,000 square miles. Challis, the county seat, was named after Alvah P. Challis, a local prospector, and evolved as a supply station for remote mining camps.

Today, Challis is a commercial center for ranching and mining operations. Thompson Creek Mining Company first staked mineral claims in 1967. After 12 years of detailed environmental and economic analysis, a proposed plan of operation was submitted to the appropriate federal agencies. In 1980, the final Environmental Impact Statement (EIS) was prepared by the Challis National Forest and BLM, Salmon District. More than $325 million were initially invested to construct Thompson Creek Mine facilities. The mine began commercial production in 1983, sixteen years after molybdenum was discovered. Since the first claims were staked in 1967, this world-class molybdenum ore deposit has been delineated by more than 300,000 feet of surface and underground drilling.

Best Management Practices Ensure State-of-the-Art Environmental Protection and Stewardship - From the first shovel of rock, Thompson Creek Mine was developed within a comprehensive framework of state and federal regulations. The mine pioneered the Interagency Task Force, a successful model for cooperative oversight by state and federal regulatory agencies. Thompson Creek has an enviable record of excellence in the areas of reclamation, environmental protection and stewardship, and has been recognized by:
_ The Idaho Conservation League
_ The Pacific Northwest Pollution Control Association
_ The University of Idaho, College of Earth Sciences
_ The Idaho Department of Lands
_ The Idaho Department of Fish and Game
_ The Idaho Division of Environmental Quality
_ The Idaho Department of Water Resources
_ The U.S. Forest Service
_ The U.S. Bureau of Land Management
