Sandra Escobar Silver-Gold Project, Durango, Mexico

Sandra Escobar is situated north of the town of Tepehuanes, Durango, in the heart of the "Mexican Silver

Trend", midway between the mining districts of Tovar and Guanacevi and is 75 km west of Silver

Standard's La Pitarrilla. This prolific trend hosts some of the world's largest silver camps and deposits,

including Fresnillo, Guanajuato, La Pitarrilla, La Preciosa, Real de Angeles and Zacatecas. Mineralization

hosted on adjacent and/or nearby properties is not necessarily indicative of mineralization hosted on the

JV’s property.

The Project consists of the Sandra Property of 6,335 hectares and Escobar Property of 635 hectares of

mineral concessions and covers multiple mineralized epithermal quartz veins, disseminated horizons and

breccia structures. These mineralized features form a high-level silver-gold-base metals system, hosted in

andesitic and rhyolitic rocks, centered on a large rhyolite dome complex in the north and silver systems

in smaller rhyolite dome complexes to the southeast . Intense alteration zones and fluid flooding in

permeable formations indicate s the presence of bulk tonnage targets. Excellent infrastructure exists in

the Sandra-Escobar area, including paved road access, electrical power, water and manpower from nearby

communities.
