TORONTO, ONTARIO - October 3, 2017 - Americas Silver Corporation (TSX: USA) (NYSE American: USAS) ("Americas Silver" or the "Company") is pleased to announce that first processing of ore from its San Rafael Project occurred in the last week of September, 2017 from development stockpiles. The first lead and zinc concentrates produced from the Company's newly modified Los Braceros Mill have been shipped to the Port of Manzanillo from the Cosalá Operations in Sinaloa, Mexico.

The reconfigured flotation circuit at the Los Braceros Mill has been successfully commissioned. Initial milling rates, metal recoveries and concentrate grades are meeting expectations and approaching steady-state targets set out in the April 2016 San Rafael Pre-Feasibility Study. The Company expects San Rafael to be the sole source of mill feed by the end of November, 2017 with commercial production expected before the end of the fourth quarter. Five development headings are currently accessing ore in the southern lobe of the Main Zone at San Rafael and will be stockpiled while the existing Nuestra Señora ore is processed. The Nuestra Señora mine is expected to be put on care and maintenance by the end of Q1 2018, although additional material is available to supplement mill feed, if required.

"Initial concentrate deliveries were on time, met internal targets and third party specifications" said Darren Blasutti, President and CEO. "Despite a transitional third quarter, the start-up of the San Rafael mine and continued strengthening of zinc and lead prices sets-up our fourth quarter and next year for significantly reduced all-in-sustaining costs and free cash flow. We expect to use this cash flow to further explore, develop and organically grow our large and prospective silver reserves and resources without equity dilution."

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.
