NOTE 3 OPERATING SEGMENT REPORTING McEwen Mining Inc. is engaged in the exploration, development, production and sale of gold and silver and exploration for copper, with operations located in the United States, Canada, Mexico, and Argentina. The Companys 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 within a geographic region are not alike. As a result, these operating segments also represent the Companys reportable segments. The Companys business activities that are not considered operating segments are included in General and Administrative and other and are provided in this note for reconciliation purposes. The CODM reviews segment income or loss, defined as gold and silver sales less production costs applicable to sales, depreciation and depletion, advanced projects and exploration costs for all segments except for the MSC segment, which is evaluated based on the attributable equity income or loss. Gold and silver sales and production costs applicable to sales for the reportable segments are reported net of intercompany transactions. Production costs applicable to sales for the El Gallo project of $11.2 million for the nine months ended September 30, 2020 (same period in 2019 - $14.6 million) include $5.2 million of residual leaching spending in the period, net of $3.1 million capitalized in inventory (same period in 2019 - $5.7 million, net of $2.7 million capitalized in inventory) with the remainder representing costs recorded in the leach pad inventory balances in prior periods. Capital expenditures include costs capitalized in mineral property interests and plant and equipment in the respective periods.
