Antofagasta (ISIN GB0000456144) faces renewed labor pressure at its Centinela mine, while Investing.com lists a 4.86 percent average analyst upside across 22 ratings. Discovery Alert reported on October 12, 2026, that 709 workers remained on strike and that voluntary mediation was scheduled for October 13, 2026.

Three events shape the dispute

On August 13, 2026, Antofagasta reported first-half revenue of USD 4.48 billion and net profit of USD 847.3 million, according to Markets Insider. On October 7, 2026, the Centinela strike began with 709 workers involved, according to Discovery Alert. On October 13, 2026, management and the unions were scheduled to resume talks at 10:00 a.m. local time, the same report said.

Dates investors can track

The immediate date is October 13, 2026, when voluntary mediation was scheduled at Centinela, according to Discovery Alert. The next earnings date listed by Investing.com is February 23, 2027.

What does the strike mean for output?

Antofagasta has kept its 2026 copper production guidance at 625,000-655,000 tonnes, according to Discovery Alert. The unions warned that Centinela output could fall 50 percent in November if the stoppage continues, while stockpiled ore may keep processing plants supplied in the near term. Centinela produced 97,100 tonnes in the first half of 2026, and its copper grade fell 14 percent, giving the dispute a measurable operating risk.

The financial contrast is substantial: first-half revenue reached USD 4.48 billion, while net profit reached USD 847.3 million, according to Markets Insider. For the stock, the key variable is whether mediation preserves the 625,000-655,000 tonne guidance or forces a later revision.
