NOTE 12 OPERATING SEGMENT REPORTING

McEwen Mining is a mining and minerals exploration company focused on precious metals in Argentina, Mexico, Canada, and the United States. The Company’s chief operating decisions maker (“CODM”) reviews the operating results, assesses performance and makes decisions about allocation of resources to these segments at the geographic region level or major mine/project where the economic characteristics of the individual mines or projects are not alike. As a result, these operating segments also represent the Company’s reportable segments. The Company’s business activities that are not considered operating segments and not provided to the CODM for review are included in Corporate and other and are provided in this note for reconciliation purposes.

The CODM reviews segment (loss) income, defined as gold and silver sales less production costs applicable to sales, mine development costs, exploration costs, property holding costs and general and administrative expenses for all segments except for the MSC segment which is evaluated based on the attributable equity income. Gold and silver sales and production costs applicable to sales for the reportable segments are reported net of intercompany transactions.

Significant information relating to the Company’s reportable operating segments is summarized in the tables below:
