The San Dimas gold-silver deposit is one of the most significant precious metal deposits in Mexico in a large and productive mining district.
The San Dimas mines are underground operations using primarily mechanized cut-and-fill mining methods. After milling, cyanidation, precipitation and smelting, dore bars are poured and then transported to the United States for refining. |
