TORONTO, ONTARIO - September 18, 2017 - Americas Silver Corporation (TSX: USA) (NYSE "MKT": USAS) ("Americas Silver" or the "Company") is pleased to provide updated mineral reserve and resource estimates for its two 100% assets, the Galena Complex in Idaho, USA and the Cosalá Operations in Sinaloa, Mexico, including the San Rafael, El Cajon, and Nuestra Senora mines, and the Zone 120 deposit.

This updated Mineral Reserve and Resource estimate reflects the drilling programs completed between January 1, 2016 and June 30, 2017 as well as production data during that period with an effective date of June 30, 2017 for the estimates. The estimate does not include drill results from holes SR399 to SR401 completed in the third quarter at the Company's Zone 120 deposit released previously, nor the associated resources attributable to the Company's option on the San Felipe property.

Highlights include:

  • Silver inventory contains 28 million ounces of proven and probable reserves, 58 million ounces of measured and indicated resources and 37 million ounces of inferred resources, a decrease of 9%, and increases of 16% and 37%, respectively.
  • San Rafael estimated proven and probable reserves increased by 512,000 tonnes (16%), 650,000 ounces of silver (6%), 12 million pounds of lead (10%), and 34 million pounds of zinc (11%).
  • Zone 120 measured and indicated resource increased by 70% to 12.6 million ounces of contained silver while the inferred resource increased to 9.6 million silver ounces with silver grades increasing by approximately 46% and 98% respectively. Drilling is expected to resume early in the fourth quarter to follow-up on the recent exploration success outlined in the August 24, 2017 press release.
  • Galena silver-lead ore proven and probable reserves were increased by 1.3 million ounces of silver, net of 18 months of production depletion.

"We're pleased to have replaced and grown our metal inventory despite minimal exploration drilling until early 2017 due to the difficult state of the precious metal industry since 2012," said Darren Blasutti, President and CEO. "The building of the San Rafael mine on time and budget coupled with the early drilling success of the adjacent Zone 120 deposit demonstrates the quality of our properties. It highlights the achievement of our disciplined capital allocation approach, prioritizing the most accretive investments to position the Company for future silver production growth without share dilution."

Compared to the last update at December 31, 2015, silver contained in the consolidated proven and probable reserves dropped 9%, or 3.0 million ounces, to 28 million ounces due to 18 months of production, the impending closure of Cosalá's Nuestra Señora mine in Q4, 2017, and the reclassification of some silver-copper material at Galena. Galena has been producing silver-lead ore since January 2016 and the reserve associated with this material increased by 18% or approximately 1.3 million ounces despite production depletion.

Silver contained in the consolidated measured and indicated resources increased by 16% to 58 million ounces. The Galena resources were roughly consistent with the 2015 report while Cosalá Operations resources were boosted by gains at Zone 120 (increased 5.2 million ounces) and the reinstatement of El Cajón (increased 5.7 million ounces) as a result of the resolution of a property boundary uncertainty in Q2, 2017. Total silver contained in the inferred category increased by 37% to 37 million ounces primarily due to the exploration success at Zone 120 in the first half of 2017.

The increase in the San Rafael reserves is expected to extend the mine life at San Rafael beyond that identified in the San Rafael Technical Report released in March 2016. The Company expects the mine life to continue to grow as current spot prices for Company's silver and the by-product metals are sustained over time and further resources are economically converted to reserves.

Recent drilling in the Company's Zone 120 deposit continues to show the prospectivity of the Company's land holding at the Cosalá Operations. The Company expects to drill additional step-out and in-fill holes in Q4, 2017 and into 2018 to potentially increase the size and understanding of the deposit after which it may assess the economic viability of the deposit as a standalone mine development scenario.

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.

CIM Definition and Standards were followed for Mineral Reserve Estimates. Mineral Reserves are estimated at a NSR cut-off value of US$40/tonne at Nuestra Señora, US$54/tonne at San Rafael and US$190/tonne at Galena. The NSR cut-off is calculated using recent operating results for recoveries, off-site concentrate costs, and on-site operating costs. Mineral Reserves are estimated using metal prices of $16.00 per ounce of silver, $2.50 per pound of copper, $0.90 per pound of lead and $0.90 per pound of zinc. Numbers may not add or multiply accurately due to rounding.

CIM Definition and Standards were followed for Mineral Resource Estimates. Mineral Resources are estimated at a NSR cut-off value of US$34/tonne at San Rafael, US$40/tonne at Zone 120, US$30/tonne at El Cajón and US$190/tonne at Galena. Mineral Resources at Nuestra Señora are estimated at a 90g/tonne silver equivalent cut-off grade. NSR and silver equivalent cut-offs were calculated using recent or expected operating results for recoveries, off-site concentrate costs, and on-site operating costs. Mineral Resources are estimated using $18.00/oz Ag, $3.00/lb Cu, $1.05/lb Pb and $1.05/lb Zn. Mineral Resources are reported exclusive of Mineral Reserves and as such the Mineral Resources do not have demonstrated economic viability. Numbers may not add or multiply accurately due to rounding.
