Map highlighting the location of each asset in the Molybdenum Business Unit across North America.

Molybdenum Business Unit Overview

The Molybdenum Business Unit includes the Thompson Creek Mine in Idaho, the Langeloth Metallurgical Facility in Pennsylvania, and the Endako Mine in British Columbia.

Molybdenum is primarily used in the production of engineered and stainless steel, enhancing strength, corrosion resistance, and performance in high-demand applications. It is a critical mineral, essential in energy transition technologies such as wind turbines, geothermal, hydrogen, and other renewable energy sources.

Thompson Creek is expected to produce a molybdenum concentrate and Langeloth processes concentrate into final molybdenum products. Together, these assets focus on the extraction and processing of molybdenum for industrial applications. Endako is a primary molybdenum mine on care and maintenance.

Thompson Creek Mine

Thompson Creek is a primary (non-by-product) molybdenum mine located approximately 48 kilometres southwest of the town of Challis in Idaho’s Custer County.

The mine, which began operations in 1983, has significant existing infrastructure, including a fleet of mobile equipment, a processing facility, and waste and tailings storage facilities with additional available capacity. At Thompson Creek, molybdenum ore is extracted using conventional open-pit mining methods and processed at the onsite mill (concentrator) to produce concentrate.

Thompson Creek is one of three primary molybdenum mines in the world, outside of China. With the scarcity of high-quality molybdenum concentrate, Thompson Creek poses a unique opportunity.

Langeloth Metallurgical Facility

The Langeloth Metallurgical Facility (“Langeloth”), located 40 kilometres west of Pittsburgh, Pennsylvania, has a long history of producing high-quality products that are sold to the metallurgical and specialty markets. It is a unique strategic asset due to its proximity to North American steel manufacturers.

Langeloth purchases molybdenum concentrate from third parties, refines into, and sells finished molybdenum products.

Endako Mine

The Endako Mine is a primary (non-by-product) molybdenum mine located near Fraser Lake, 161 kilometres northwest of Prince George, British Columbia. Centerra holds a 75% interest in the mine with Moon River Capital Ltd. holding a 25% interest.

The mine was placed on care and maintenance in July 2015.
