| Copper a (billion pounds) |  | Gold (million ounces) |  | Molybdenum (billion pounds) |
North America | 48.6 |  |  | 0.6 |  |  | 2.83 |  |
South America | 31.7 |  |  | — |  |  | 0.70 |  |

Consolidated basis c | 111.0 |  |  | 26.9 |  |  | 3.53 |  |
Net equity interest b,d | 80.4 |  |  | 13.5 |  |  | 3.20 |  |
Note: Totals may not foot because of rounding. a.Estimated consolidated recoverable copper reserves included 1.8 billion pounds in leach stockpiles and 0.3 billion pounds in mill stockpiles. b.Estimated recoverable proven and probable mineral reserves from Indonesia reflect estimates of minerals that can be recovered through 2041. As a result, PT-FI’s current long-term mine plan and planned operations are based on the assumption that PT-FI will abide by the terms and conditions of the IUPK and will be granted the 10-year extension from 2031 through 2041 (refer to Note 13 for discussion of PT-FI’s IUPK). As a result, PT-FI will not mine all of these mineral reserves during the initial term of the IUPK. Prior to the end of 2031, PT-FI expects to mine 46% of its proven and probable recoverable mineral reserves at December 31, 2022, representing 49% of FCX’s net equity share of recoverable copper reserves and 51% of FCX’s net equity share of recoverable gold reserves. c.Consolidated mineral reserves represent estimated metal quantities after reduction for joint venture partner interests at the Morenci mine in North America (refer to Note 3 for further discussion). Excluded from the table above were FCX’s estimated recoverable proven and probable mineral reserves of 340 million ounces of silver, which were determined using $20 per ounce. d.Net equity interest mineral reserves represent estimated consolidated metal quantities further reduced for noncontrolling interest ownership (refer to Note 3 for further discussion of FCX’s ownership in subsidiaries). Excluded from the table above were FCX’s estimated recoverable proven and probable mineral reserves of 226 million ounces of silver.
