| (a) | WIP inventories represent mill and leach stockpiles that have been extracted from the open pit and are available for copper recovery. Based on the future mine plan production, the Company identifies the portion of inventory that is classified as current or non-current. For mill stockpiles, recovery is through milling and concentrating. For leach stockpiles, recovery is through exposure to acidic solutions that dissolve copper and deliver it in a solution to extraction processing facilities. During 2022, the Company recorded metal inventory adjustments totaling US$7.7 million associated with the write-off of certain long-term mill and leach stockpiles. No metal inventory adjustments were recorded in 2021.
