Xiamen Tungsten announced that its joint venture Luoyang Yulu has essentially ceased production after partner CMOC Group stopped supplying tailings. Luoyang Yulu, 60% owned by Xiamen Tungsten and 40% by CMOC, has been recovering scheelite from CMOC's molybdenum flotation tailings for over 20 years. In the first half of 2026, the venture posted a net profit of approximately 336 million yuan, more than 2.7 times its full-year 2025 profit, before production was forced to a halt. CMOC cited compliance with national tungsten mining regulations for the supply suspension; Xiamen Tungsten stated that "both parties are still in communication." In 2025, Luoyang Yulu contributed 61.3684 million yuan, or 2.66%, to Xiamen Tungsten's attributable net profit. This incident exposes Xiamen Tungsten's insufficient tungsten resource self-sufficiency and the long-standing resource competition challenges in China's rare metals supply chain.
