Ore m ineral resource is used for an indication of ore that is potentially extractable, and the term ore mineral reserve is used for a well defined (proven), profitable amount of extractable ore. McKelvey diagram showing different definitions for different degrees of concentration and understanding of mineral deposits. 16.1.3. Mining Techniques
(4) "Ore" means raw materials in their natural state or condition prior to beneficiation or processing, and includes mined raw materials extracted prior to further processing. "Ore" includes any metalliferous material whose metal content is less than 15% and does not include any material whose metal content is 15% or greater.
