    two costs models cannot be added together to yield mining and milling operating costs on a common basis such as per tons of ore mined and milled without conversion. To determine if a deposit is economic using the models of Camm 1991 one must first calculate total lifeofmine capital and operating costs and compare them with total lifeof.
