Americas Silver Corporation Provides Updated Mineral Reserve And Resource Estimates

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.
