Mineral Resources are not Mineral Reserves and do not demonstrate economic viability. There is no certainty that all or any part of the Mineral Resource will be converted to Mineral Reserves. Quantity and grade are estimates and are rounded to reflect the fact that the resource estimate is an approximation.
