TORONTO, ONTARIO — May 31, 2017 — Americas Silver Corporation (TSX: USA) (NYSE “MKT”: USAS)
(“Americas Silver” or the “Company”) today provided an exploration update for its Galena Complex
located in Idaho, USA and its Cosalá Operations located in Sinaloa, Mexico.
Exploration Highlights
Galena Complex
A new silver‐lead zone (366 FW Vein) was discovered within 30 meters of existing reserves in the
footwall of the 360 Vein on the 4900 Level. Significant intercepts include 2.8 meters at 347g/t
silver and 14.0% lead and 12.8 meters at 116g/t silver and 5.6% lead.
Drilling on the 3400 Level in a previously unexplored area encountered a new zone of strong silver‐
lead mineralization 135 meters south of existing workings.
Step out drilling on the 4000 Level extended known mineralization 90 meters laterally and 50
meters vertically. Significant intercepts include 17.2 meters at 154g/t silver and 7.3% lead and
2.6 meters at 340g/t silver and 15.9% lead.
Cosalá Operations
Infill drilling at the southern part of San Rafael’s Main Zone confirmed the existing zinc‐silver‐lead
resource model in preparation for first ore production at the end of the third quarter.
San Rafael’s Zone 120 infill and extension drilling was completed. Assay results are pending but
core logging indicates that existing silver‐copper mineralization extends an additional 350 meters
to the southeast and remains open in that direction. The newly discovered mineralization is less
than 600 meters from the El Cajón silver‐copper mine.
Drilling at Los Manueles has started with initial results expected before the end of the second
quarter.
