Production
Mineralized material at San José is processed at a mill site, with half of the concentrate material produced being processed into doré, and the balance filtered and shipped as concentrate. The mine has been in commercial production for over 12 years and is estimated to continue producing gold and silver into 2024, according to the December 2018 assessment. The life of the mine continues to be updated as exploration advances and reserve estimates are renewed.
McEwen Mining's attributable production for 2020 at San José was of 31,800 gold ounces and 2,013,000 silver ounces. In 2020 the mine operated under capacity as a result of lockdowns and travel restrictions imposed by the government in relation to COVID-19. For the nine months ending September 30, 2020, cash costs and all-in-sustaining costs per ounce of gold equivalent were $1,232 and $1,536, respectively.
