Major Tunnel Collapse at DRC's Rubaya Mine Threatens 15% of Global Tantalum Supply

According to SMM estimates, China's refined bismuth production in June 2026 will show little change compared with May, edging up by less than 1% month-on-month. Many market participants expect that the tightness in raw material supply for domestic bismuth producers is unlikely to ease significantly as summer sets in, and production will likely continue to be constrained. Refined bismuth output is expected to remain largely steady, though a decline cannot be ruled out.

According to SMM estimates, China's antimony ingot production (including antimony ingots, crude antimony on a converted basis, cathode antimony, etc.) in June 2026 edged up by approximately 2% month-on-month, showing a notably stable trend overall.

[Tungsten Flash] SMM July 1 News: Xiamen Tungsten announced that its 60%-owned subsidiary Luoyang Yulu Mining has completely halted production. The enterprise relies on CMOC’s molybdenum beneficiation tailings to extract scheelite concentrates. Now, due to CMOC suspending tailings delivery, it has no raw materials for production, and the timing for production resumptions is undetermined. According to the announcement, Luoyang Yulu’s production and sales of scheelite concentrates (WO3 metal content) in 2025 were 1,924 mt and 1,614 mt, respectively, and in H1 2026, production and sales were 685 mt and 669 mt, respectively. This production halt is expected to have some impact on the company’s near-term operating performance. As it is currently impossible to determine how long Luoyang Yulu’s suspension will last, the impact on the company’s performance cannot be predicted at this time. Specific circumstances will be subject to the company’s audited financial reports.
