The Canada-based producer confirmed that the closures are in direct response to the diagnoses of its miners; the workers were found to be positive during routine testing and tracing procedures at the mines. 

Reduced workforces will conduct care and maintenance activities at Huaron and Morococha until it is determined that normal operations can safely resume, it said.

Pan American owns 92.3% of Morococha and 100% of Huaron, another polymetallic silver mine near Pasco, Peru. The miner also has operating assets in Canada, Mexico, Argentina and Bolivia.
