Americas Silver Corporation Provides an Update on San Felipe Resource Estimate - Seite 2

“With the significant increase in contained zinc and silver in the indicated resource, San Felipe now becomes a more substantial project in the current zinc market,” stated Darren Blasutti, President and CEO of Americas Silver Corporation. “The updated estimate at San Felipe highlights potential for another low-capital project for the Company, after our successful start-up of the San Rafael mine and the rapid resource expansion of the silver-rich Zone 120 deposit. We will continue to evaluate San Felipe for its economic merits and strategic fit ahead of making the final payments for the option on the property by the end of the year.”

Work during the past year on the San Felipe property included a six-hole, twinning diamond drill hole program to provide confirmation of historical drilling data, an updated interpretation of the mineralization and mineral resource estimate by Mine Development Associates (“MDA”), and a preliminary geotechnical review of the property by Adiuvare GE. Both MDA and Adiuvare GE are independent consulting firms. The twinning program confirmed the historical drilling data and provided increased confidence in the existing dataset. Three holes were drilled into each of the La Ventana and San Felipe zones. These two zones are the most significant mineral occurrences identified on the property in terms of contained metals, contributing 100% of the indicated mineral resources and approximately 50% of the inferred mineral resources on a tonnage basis.

Geology and Mineralization

There are four deposits that contribute to the current mineral resource estimate: La Ventana, San Felipe, Transversales and Las Lamas. The Zn-Ag-Pb mineralization occurs as skarn-related massive sulfide replacement veins, often cut by late quartz veins. It appears that the late quartz is associated with increased silver, copper and gold.

The potentially economic sulfide veins (>2.5% ZnEq) are usually 2 to 10 meters wide and occur within much wider near-vertical structural zones marked by strongly silicified, weakly brecciated, andesite country rock. There is significant faulting sub-parallel to the structural and mineral zones while cross-faults off-set the mineralized structures.

A granitic batholith borders the south side of property and cuts off the southwestern extension of the Las Lamas zone. The granodiorite is also encountered at depth within the San Felipe and La Ventana deposits and in the latter deposit appears to form the footwall boundary to the mineralized structural zone. The granodiorite is likely pre-mineral, or possibly contemporaneous, with the early massive sulfide skarn, though is not as amenable to skarn alteration as the andesite. Mineralization within the granodiorite occurs primarily within narrow fractures and thin veins. Rhyolite intrusives, often significantly faulted and dismembered, occur within the andesite and like the granodiorite are not as amenable to skarn alteration but can be host to more fracture-controlled mineralization.
