TORONTO, Feb. 12, 2018 /CNW/ - Sierra Metals Inc. (TSX: SMT) (BVL: SMT) (NYSE AMERICAN: SMTS) ("Sierra Metals" or "the Company") has filed a technical report prepared in accordance with National Instrument 43-101 ("NI 43-101") on the Cusi Mine (the "Report"). The Report supports the disclosure made by the Company in its news releases dated December 29, 2017 entitled "Sierra Metals Significantly Increases Mineral Resource Estimate for Cusi Mine, Mexico." There are no material differences in the mineral resources contained in the Report from those disclosed in the December 29, 2017 news release.
The Report included mineral resources for the Cusi Mine with:
- Total Measured and Indicated Resources increased 129% to 4,557,000 tonnes from 1,990,000 tonnes previously reported, and Total Inferred Resources increased 36% to 1,633,000 tonnes from 1,200,000 tonnes previously reported
- Total Measured Mineral Resources for Cusi are 362,000 tonnes averaging 225g/t silver, 0.55% lead, 0.68% zinc, 0.13 g/t gold for a total 268 g/t AgEq
- Total Indicated Mineral Resources for Cusi are 4,195,000 tonnes averaging 217 g/t silver, 0.64% lead, 0.66% zinc, 0.21 g/t gold and 267 g/t AgEq
- Total Inferred Mineral Resources for Cusi are 1,633,000 tonnes averaging 158 g/t silver, 0.54% lead, 0.84% zinc, 0.16 g/t gold and 207 g/t AgEq
- The updated Resource Estimate varies from the previous 2017 Technical Report due to a variety of factors, including the use of silver equivalent cut-off grade and depletion by production since the previous Report was completed
- The updated Resource Estimate has incorporated new exploration drilling, sampling, and underground mapping information into the geologic interpretation and grade estimations providing more refined resource models in the areas of San Nicolas and Promontorio
The Report dated February 9, 2018 with an effective date of August 31, 2017 is entitled "NI 43-101 Technical Report on Resources Cusi Mine Mexico", and was prepared by independent SRK Consulting (U.S.), Inc.

Notes on the Resource Estimate
The procedures and methods supporting the mineral resource estimation have been developed in conjunction with Dia Bras geological personnel. The understanding of the geology and mineralization at Cusi is based on a large volume of geologic data as well as a robust history of production. SRK has reviewed the methods and procedures for data collection methods supporting the estimate, and notes that they are reasonable and consistent with industry best practice. Geology models were generated by Dis Bras geologists using Leapfrog Geo, and locally vary significantly from those used in previous reports. A combination of diamond drilling, channel sampling, and mine mapping have been used to inform these models, and SRK is of the opinion that they are an accurate interpretation of the mineralization at Cusi. These models, presented as 3D wireframes, are used to constrain block models, which are flagged with variables such as bulk density, mine area, depletion, etc.
The resource estimations presented herein have been conducted or reviewed by independent consultants using supporting data generated by the site. SRK conducted independent estimations for the Cusi Mine. Grade for the four primary commodities (Ag, Au, Pb, Zn) is estimated into the block models using both drilling and channel samples, applying industry-standard estimation methodology. Interpolation methods were generally via inverse distance. Mineral resources estimated by the independent consultants are categorized in a manner consistent with industry best practice, and are reported above reasonable unit value cut-offs based on actual marginal production costs to satisfy public reporting criteria.
SRK is of the opinion that the resource estimations are suitable for public reporting and are a fair representation of the in-situ contained metal for the Cusi deposit.
The information in this announcement regarding the Resource Estimate included in the Report is qualified in its entirety by reference to the Report. The Report is available for review on SEDAR (www.sedar.com), EDGAR (www.SEC.gov) and the Company's website (www.sierrametals.com).
