智通财经APP获悉，东方证券发布研报称，全球第二大铜矿Grasberg宣布重启和复产计划，预计未来产 量持续增长。该行认为，在中期矿端干扰被逐渐排除的情况下，如Grasberg、Cobre Panamá等铜矿的重 新恢复正常生产或将显著贡献矿端增量，铜矿供给端的紧张局势有望得到缓解。另指铜冶炼费或存边际 向上改善空间，关注中期铜冶炼企业的投资机会。 东方证券主要观点如下： 全球第二大铜矿Grasberg宣布重启和复产计划，预计未来产量持续增长 26-27年铜冶炼产量增速或低于铜矿供给端，铜冶炼费有望边际向好 在中期矿端干扰被逐渐排除、大型铜矿有望复产的预期下，26-27年铜矿供给端放量增速或较25年显著 提升，据测算26-27年铜矿产量增速同比可达3.3%、5.3%。当前海外多家冶炼厂因铜精矿紧缺、成本高 企而收缩产能，叠加国内中游铜冶炼端"反内卷"政策措施落地的预期，中期铜冶炼产量增速或低于铜矿 供给端。该行认为，铜冶炼费或存边际向上改善空间，关注中期铜冶炼企业的投资机会。 投资建议与投资标的 铜冶炼端：建议关注全国最大铜冶炼企业之一、且具有米拉多铜矿资源放量提升铜精矿自给率预期的铜 陵有色(000630. ...
