Fresnillo PLC on Monday said operations at the Herradura mine in Mexico were temporarily halted by an illegal stoppage from a ‘very small group’ of unionised workers at its wholly-owned subsidiary, Minera Penmont.

‘The stoppage, which prevented site access for other workers, was not approved by the union, nor supported by the vast majority of unionised workers at Herradura, with whom Penmont has a very constructive and long-term relationship,’ Fresnillo said.

The stoppage has since ended, Fresnillo said, and all production activities recommenced. The incident is not expected to materially affect overall production, and Fresnillo left full-year production guidance unchanged.

Herradura is one of Fresnillo’s eight operating mines in Mexico. It is one of the country’s largest open-pit gold mines, producing 55% of Fresnillo’s total gold output in 2022.

Fresnillo shares were 0.1% higher at 682.00 pence each on Monday morning in London.
