Antofagasta share price slips in London as Twin Metals vote and copper swings keep traders cautious
Antofagasta plc shares fell 0.6% to 3,495 pence in early London trading. The U.S. House voted 214-208 to overturn Minnesota’s mining ban, potentially reviving Antofagasta’s Twin Metals project if the Senate agrees. Copper prices rose 0.4% after recent volatility, with analysts citing tight supply and weak Chinese demand. Investors await Antofagasta’s quarterly update on Jan. 29.
