Mineral Reserves & Resources

Notes to Mineral Reserves & Resources

CIM (2014) Definition Standards were followed for Mineral Reserves. Mineral Resources are inclusive of Mineral Reserves. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. Tonnage and grade measurements are in metric units. Contained gold is reported as troy ounces. Mineral resources do not include factors such as mining dilution or mining recovery. There is no certainty that the mine plans and economic models contained in any of the reports will be realized. Numbers may not add due to rounding. See Cautionary Notes on this website.

Details of cut-off grades, bulk densities, mining widths, dilution, mining factors, and process recovery assumptions applied to Mineral Reserves and Mineral Resources are provided in the Technical Reports for each mine/project.
