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:
San Julián is an underground mine which develop ore veins and disseminated ore body.
There are three parallel sequence areas of disseminated ore body mined by 16 m x 25 m x 20 m (WxHxD) stopes units with subsequent backfill.
