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.

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 veins form a high -level silver-gold-base metals system, hosted in andesitic and

rhyolitic rocks, centered on a large rhyolite dome comple x in the north and silver systems in smaller

rhyolite complexes to the southeast. Intense alteration zones and fluid flooding in permeable formations

indicates 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.
