东方证券：全球第二大铜矿宣布复产计划 中期铜冶炼费或存上行预期

Group 1 - The global second-largest copper mine, Grasberg, has announced a restart and production resumption plan, with expected continuous growth in output [1] - Grasberg's copper production is projected to remain at 1 billion pounds (approximately 454,000 tons) in 2026, with an average annual output potentially reaching 1.6 billion pounds (approximately 726,000 tons) from 2027 to 2029 [1] - If Grasberg successfully follows the restart schedule, it could contribute an incremental copper output of approximately 70,000 tons in 2026 and 2027, potentially increasing global copper mine production growth rate to about 3.3% in 2026 [1] Group 2 - Other copper mines, such as Cobre Panamá, are also expected to resume production, with a peak annual capacity of 300,000 to 350,000 tons of copper, accounting for about 1.5% of global copper supply [2] - The Panamanian government is preparing to negotiate with First Quantum regarding the restart of Cobre Panamá, with talks expected to begin by the end of 2025 or early 2026 [2] - The gradual removal of mid-term mining disruptions is anticipated to significantly contribute to the incremental supply from mines like Grasberg and Cobre Panamá, alleviating the tight supply situation in the copper market [2] Group 3 - The growth rate of copper smelting production in 2026-2027 is expected to be lower than that of the copper mine supply side, with copper mine production growth rates projected to reach 3.3% and 5.3% year-on-year [3] - Many overseas smelting plants are reducing capacity due to tight copper concentrate supply and high costs, while domestic copper smelting policies are expected to lead to a lower growth rate in smelting production compared to the supply side [3] - There is potential for marginal improvement in copper smelting fees, indicating investment opportunities in mid-term copper smelting enterprises [3] Group 4 - Investment recommendations include focusing on Tongling Nonferrous Metals Group, one of the largest copper smelting companies in China, which has expectations for increased self-sufficiency in copper concentrate due to the Mirador copper mine [4] - Other recommended stocks include Zijin Mining, which has significant resource reserves and expectations for continued copper mine expansion [4] - Additional stocks to consider are Jiangxi Copper and Luoyang Molybdenum, which have not been rated yet [4]
