Some 230 people have been confirmed dead, while rescuers are still trying to reach children trapped under a collapsed primary school in Mexico City.
In a statement, the gold and silver group added it was deeply saddened by the catastrophe.
“Fresnillo‘s absolute priority is the safety of its staff. Following the earthquake the building of the company’s corporate headquarters in Mexico City was assessed by specialists who confirmed there had been no structural damage and the building was therefore declared fully safe to occupy. All administrative functions were resumed after the assessment.”
