Two employees of precious metals producer Primero Mining, plus a relative of one of the employees, have died following an aircraft crash-landing in the Sierra Madre mountain range, about 15 km from the Tayoltita airport, close to Primero’s San Dimas mine in Mexico. Late on Friday, the miner reported that Toronto-based executive and VP for operations Guillermo Adrian, San Dimas-based warehouse clerk José Paz Vizcarra Juarez, as well as a family member of Vizcarra Juarez, had died.
