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 14 years and is estimated to continue producing gold and silver into 2027, according to the operator's 2021 Full Year Results report. The life of the mine continues to be updated as exploration advances and reserve estimates are renewed.
