Cost of sales includes mine site operation costs such as mining, processing, administration, royalties and production taxes, but is exclusive of amortization, reclamation, capital and exploration costs. The measure, along with gold ounces sold, is considered to be a key indicator of a company's ability to generate operating earnings and cash flow from its mining operations.
