Mineral Resources are reported inclusive of Ore Reserves. Reserves Mining depletion has not been accounted for between 31 December 2019 and 30 June 2020.
1 Includes stockpiles
2 Ernest Henry Operation cut-off 0.9% CuEq
3 Red Lake cut-off is 3.3g/t Au except fo Cochenour (3.0g/t Au) and HG Young (3.2g/t Au) deposits
This information is extracted from the ASX release entitled “Annual Mineral Resources and Ore Reserves Statement” released to the ASX on 12 February 2020, ASX release entitled “Cowal Maiden Underground Ore Reserve Supports Mine Development” released on 23 July 2020 and “Red Lake 11 Million Ounce JORC Code Mineral Resource” released on 13 August 2020. This table excludes Cracow Mineral Resources following divestment as advised on 1 July 2020 in ASX release entitled “Completion of Cracow Gold Mine Divestment”. An improved understanding of the geological controls has indicated a potential reduction of approximately 75,000 ounces from the Life of Mine Plan as advised in the ASX release on 19 June 2020 entitled “Mt Carlton Update”. The Mt Carlton Mineral Resources and Ore Reserves will be updated in the Annual Mineral Resources and Ore Reserves Statement at December 2020 planned for release in February 2021.
