El Rayo Primary Silver Project:
Las Bolas Alteration
From earliest to latest:
Propylitic alteration (epidote-chlorite-quartz) bordered by sub-
propylitic alteration (smectite-chlorite-calcite) along veins
Sericite alteration of plagioclase
Hematite alteration of Fe-bearing minerals
Argillic and minor advanced argillic (dickite filling open spaces)
Carbonate alteration closely associated with late cross-cutting
andesite dikes

El Rayo Measured & Indicated in-pit resource of77.4 mill ion ounces of silver;
59 million ounces occur in the Las Bolas deposit
Multi-event low sulphidation system consisting of stockwork and vein-breccia
Silver mineralization related to quartz-specularite and specularite veinlets
Low total sulphide; trace amounts of Pb, Zn and Cu sulphidesGangue mineralogy dominated by quartz and specularite with mimetite and
vanadinite
Alteration consists of propylitic, sericitic, hematitic and argillic alteration along
with limited silicification
Two distinct events: higher temperature Pb-As-V-Ag-Mo followed by lower
temperature Ag-Pb-Zn

El Rayo Primary Silver Project: Where to Next?
Continue to expand resource at Las Bolas Northeast and
La Soledad West
Define sulphide-rich mineralization at depth at Las Bolas
Refine interpretation of fault offsets in order to locate additional resource;
detailed structural analysis
Expand existing Au resource in El Rayo zone
Indicated: 380,000 tonnes @ 1.85 g/t Au containing 22,600 oz. Au
Inferred: 365,000 tonnes @ 1.61 g/t Au containing 18,900 oz. Au
Follow-up regional geophysical and geochemical anomalies
Increase understanding of district-scale mineralization Why two distinct styles of mineralization?
o Isotopic study
o Age dating
