The terms "resources" and "reserves" are commonly used in the mining and minerals industry to refer to different types of mineral deposits. "Resources" are minerals that have been identified and are potentially extractable, while "reserves" are minerals that have been identified and are currently profitable to extract. Therefore, the best choice is D, as it correctly identifies both types of mineral deposits and distinguishes between them. The other answer choices do not accurately describe the concept of mineral resources and reserves.
