CutOff Grades For Mineral Resource Reporting: Going The

A cutoff grade (COG) is an industryaccepted standard expression used to determine what part of a mineral deposit to include in a mineral resource estimate (MRE). For MRE reporting, COGs tend to be rounded down to ensure that material of no economic significance is excluded from the resource. To calculate a COG, we can gauge the likely
