Segment Reporting [Abstract]

Segment Information

Segment Information

TCM has three reportable segments, based on products and geography: US Operations Molybdenum, Canadian Operations Molybdenum and Copper-Gold (Development). The US Operations Molybdenum segment includes all mining, milling, mine site administration, roasting and sale of molybdenum products from the TC Mine and the Langeloth Facility, including the roasting at the Langeloth Facility of molybdenum products from the Endako Mine and all roasting and sales of third-party purchased material. The Canadian Operations Molybdenum segment includes all mining, milling, mine site administration, roasting and sale of molybdenum products from the 75% owned Endako Mine. The Copper-Gold (Development) segment includes all development expenditures and development site administration from Mt. Milligan. The Inter-segment represents the elimination of management fee income, revenue and cost of sales of product transported from the Canadian Operations to the US Operations for processing.

TCM's chief operating decision makers (Chief Executive Officer and Chief Operating Officer) evaluate segment performance based on segment revenue less costs and expenses. TCM attributes other income and expenses to the reporting segments if the income or expense is directly related to segment operations, as described above. TCM does not allocate corporate expenditures such as general and administrative, exploration and interest income and expense items to its reporting segments, unless such expenditures are directly related to segment operations. Segment information for the three and six months ended June 30, 2013 and 2012 was as follows:
