Highlights of the program include:

• Step-out hole SR-396 with 61.4 meters grading 306g/t Ag, 0.23g/t Au and 0.79% Cu (412g/t AgEq) including 5.9 meters of 932g/t Ag, 0.82g/t Au and 1.94% Cu (1,213g/t AgEq) plus another interval of 9.4 meters grading 479g/t Ag, 0.29g/t Au and 1.07% Cu (622g/t AgEq)
• Step-out hole SR-401 with 39.6 meters grading 205g/t Ag, 0.28g/t Au and 0.53% Cu (289g/t AgEq) including 11.4 meters of 473g/t Ag, 0.68g/t Au and 1.20% Cu (659g/t AgEq)
• Infill hole SR-391 with 22.8¹ meters grading 138g/t Ag, 0.22g/t Au and 0.37% Cu (196g/t AgEq²) including 4.0 meters of 460g/t Ag, 0.20g/t Au and 0.88% Cu (575g/t AgEq)
• Infill hole SR-392 with 18.1 meters grading 113g/t Ag, 0.08g/t Au and 0.17% Cu (138g/t AgEq)

"We are very encouraged by the initial success of this drilling," said Darren Blasutti, President & CEO of Americas Silver Corporation. "Not only did the infill drilling increase the confidence of the existing resource at Zone 120, but the step out drilling to the southern extension confirms our geologists view of a larger, more robust system which could extend to the El Caj??n deposit."

2017 Cosal?? Exploration Program

Exploration drilling resumed at the Cosal?? Operations property for the first time since 2014. Starting in April, an initial eight hole, 4,000 meter diamond drill program at Zone 120 was focused on upgrading the existing resource³ as well as expanding the footprint of mineralization to the southeast. Following up on the success of step-out hole SR-396, the Company drilled an additional 2,000 meters in four holes to test continuity of the mineralization. Detailed exploration results from the drill program can be found on the Company's website at americassilvercorp.com. Assays from hole SR-402 are still pending.

Silver-copper mineralization is hosted in limestone adjacent to a large intrusive and related dikes which underlies most of the area shown in the map above, including the approximately 500 meter unexplored gap between Zone 120 and El Caj??n. Mineralization occurs in discreet horizons and lenses of tetrahedrite and chalcopyrite localized in structural traps created by dikes and contact irregularities of the intrusive. Additional drilling in 2017 is planned to extend and further define the mineralization as well as to support economic and technical studies aimed at evaluating potential development scenarios. The potential project will benefit from its close proximity to the San Rafael deposit, currently in development.

Drill core samples are prepared at the Company's secure facility in Cosal??, Sinaloa. Assaying was done by Chemex Labs in Hermosillo, Mexico. The Company has a QA/QC program supervised by a Qualified Person.

Cautionary Note to U.S. Investors:

The terms "mineral resource", "measured mineral resource", "indicated mineral resource", "inferred mineral resource" used in the press release are Canadian mining terms used in accordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects under the guidelines set out in the Canadian Institute of Mining, Metallurgy and Petroleum Standards. Mineral resources which are not mineral reserves do not have demonstrated economic viability.

While the terms "mineral resource", "measured mineral resource", "indicated mineral resource", and "inferred mineral resource" are recognized and required by Canadian regulations, they are not defined terms under standards in the United States and normally are not permitted to be used in reports and registration statements filed with the Securities & Exchange Commission ("SEC"). As such, information contained in the Company's disclosure concerning descriptions of mineralization and resources under Canadian standards may not be comparable to similar information made public by U.S companies in SEC filings. With respect to "inferred mineral resource" there is a great amount of uncertainty as to their existence and a great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an "inferred mineral resource" will ever be upgraded to a higher category. Investors are cautioned not to assume that any part or all of mineral deposits in these categories will ever be converted into reserves.
