Antofagasta Stock Plunges Over 5 Percent Amid Copper Market Volatility
Antofagasta plc's stock (ISIN GB0000456144) plummeted over 5 percent in London trading on September 10, 2026, as the copper miner struggled with volatility in the copper market.
The shares retreated from recent highs near 39.59 pounds, according to Teleborsa, and are now testing a resistance area around that level.
Meanwhile, investors are still digesting Antofagasta's most recent interim results, which showed an 18 percent rise in revenue to about USD 4.5 billion in the first half of 2026 compared with the prior-year period, driven by higher copper margins.
The company reported a 27 percent year-on-year increase in EBITDA to roughly USD 2.8 billion, lifting the EBITDA margin to 63.4 percent and pushing profit before tax up by 72 percent for the half-year.
