Andean Precious Metals reported a fatality at its San Bartolome silver plant in Bolivia.
The accident happened at approximately 5 30 pm, local time, on May 4.
No other workers were harmed by the accident.
"Our thoughts are with the individual's family, friends, and coworkers during this difficult time," Andean Precious Metals chief executive Simon Griffiths said.
"The health and safety of our workforce remains our utmost priority."
Andean Precious Metals said in April that it would delay an expansion study of the Bartolome mine due to delays in metallurgical testing.
The company is planning to start tin mining at the mine complex, by mining a fines disposal facility adjacent to the tailings facility.
The fines disposal facility contains indicated mineral resources of 10.5 million tonnes, with 16.2 million silver ounces and 11,930 tonnes of tin. Inferred mineral resources of the FDF are 1.51 million tonnes, with 2.3 million ounces of silver and 1,330 tonnes of tin.
