| Mine Life | 9 years (as of Jan 1, 2017) |
Silver production from mines reached a record level of 54.2 moz, due to phase I at San Julián operating at full capacity for the entire year and the start of operations of phase II at the same mine. |
Deposit Type
- Epithermal
- Vein / narrow vein
Summary:
The San Julián project comprises a series of silver-gold veins as well as disseminated ore.
The new San Julian mine in construction displays a silver resource of 200 Moz in two different types of ore bodies: (i) typical low sulphidation epithermal veins and (ii) disseminated sulphides in subvolcanic and volcanic felsic rocks. Exploration strategy involved early recognition of Cienega-style characteristics providing confidence in the geologic model, and persistence when evaluating the non-typical disseminated mineralization.
Summary:
Underground mine, flotation plant and a dynamic leaching plant.
The San Julián project includes construction of two plants: 1) a dynamic leaching plant to treat ore from the veins
2) a flotation plant with 6,000 tpd capacity to process ore from the disseminated body.
