Opening a new mine or expanding an existing operation can be a challenging and daunting task. Aside from assessing and evaluating social-environmental concerns and designing the mining and material movement approach, the first question often asked is, "how much will it cost us to mine?" This may need to be determined even before you decide that there is a potential project.
