Mine production
The Pirquitas mine produced 8.6 million ounces of silver during 2012, 22% more than the 7.1 million ounces produced in 2011. The higher 2012 production is the result of better mechanical availability in the plant and operational improvements that led to higher and more consistent throughput. The mine also produced 11.2 million pounds of zinc, 10% more than the 10.1 million pounds produced in 2011, again largely the result of higher throughput.
During the year, 1.6 million tonnes of ore were processed at an average milling rate of 4,433 tonnes per day, 11% above the plant’s nominal design. This compares to 1.1 million tonnes processed in 2011, at an average milling rate of 2,983 tonnes per day. The ongoing performance above design was the result of continuous improvement initiatives at the mine, including improved preventative maintenance.
The average silver grade of the ore milled in 2012 declined to 217 g/t from 253 g/t in 2011. The average silver recovery rate declined to 76.3% in 2012 from 79.5% in 2011, partly due to a temporary shortage in the desired reagents. Despite lower grades and recoveries, overall production improved due to the higher average milling rate.
Mine operating costs
Cash costs per ounce and total cost per ounce are non-GAAP financial measures. See “Cautionary Note Regarding Non-GAAP Measures.”

During 2012, the Company changed its presentation of cash costs, a non-GAAP financial measure. Under the revised methodology, the Company reports “cash costs” and “total costs” on a “per payable ounce sold” basis. Silver concentrate export duties, that are being accrued but not paid, are included in total costs to reflect their non-cash nature. Previous disclosures have been restated to conform to the amended presentation.

Notes:
Jeremy D. Vincent , B.Sc. (Hons),P.Geo ., Senior Geologist employed by the Company, is the Qualified Person for the reported Mineral Resources estimate.- All Mineral Resource estimates have been classified in accordance with current
Canadian Institute of Mining , Metallurgy and Petroleum (“CIM”) definition standards. - The above Mineral Resources are reported at a range of potentially economic silver cut-off grades to demonstrate sensitivity, whilst retaining reasonable prospects for economic extraction. The cut-off grade of 50 grams per tonne silver has not yet been demonstrated by a preliminary economic assessment or higher level mine study.
- Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. While the classification categories of Mineral Resources used in this news release are recognized and required under Canadian regulations, the
U.S. Securities and Exchange Commission (“SEC”) does not recognize them and U.S. companies are generally not permitted to disclose resources in documents they file with theSEC . - The reported tonnes, grade, and metal content may not tally precisely due to rounding.
Outlook
This section of the news release provides management’s production and cost estimates for 2013. Major capital and exploration expenditures are also discussed. See “Cautionary Note Regarding Forward-Looking Statements.”
The Company’s production and cost guidance for 2013 is:
- Produce and sell between 8.2 and 8.5 million ounces of silver.
- Produce over 20 million pounds of zinc.
- Cash costs between
$17.00 and $18.50 per silver ounce. - Capital expenditures of
$25 million at Pirquitas, including approximately$15 million for a tailings facility expansion but excluding capitalized stripping costs. - Expenditures of
$15 million for exploration across the Company’s portfolio. - Expenditures of
$17 million for development.
At the Pirquitas mine the Company expects to produce between 8.2 and 8.5 million ounces of silver in 2013. The mine is currently transitioning from Phase 1 to Phase 2 of the

Notes to Mineral Reserves and Resources Table:
All estimates of Mineral Reserves and Mineral Resources in Table 1 have been prepared in accordance with NI 43-101 under the supervision of a Qualified Person named below for the respective properties. Mineral Resources which are not Mineral Reserves do not have demonstrated economic viability. Mineral Resources and Mineral Reserves figures have been rounded to the nearest 0.1 million tonnes and the nearest 0.1 million ounces for silver and the 0.01 million ounces for gold. Exact totals can be found in the corresponding NI 43-101 Technical Report for each property.
All Technical Reports referenced below are available under the Company’s profile in SEDAR or on the Company’s website at www.silverstandard.com.
Pirquitas
- Mineral Reserve and Mineral Resource estimates are reported below the as-mined surface as at
December 31, 2012 . The Mineral Reserves estimate was completed by Andrew W. Sharp FAusIMM andTrevor J. Yeomans ,P.Eng ., ACSM, as Qualified Persons in accordance with the standards of NI 43-101. Mineral Reserves are presented at a cut-off ofUS$35.52 per tonne net smelter return (“NSR”), usingUS$25.00 per troy ounce silver andUS$2,403.00 per tonne zinc; these values remain the same as used in the 2011 Pirquitas Technical Report. Mineral Resources for the Mining Area (includesSan Miguel ,Potosi , and Oploca zones) were estimated by Dr.Warwick S. Board ,P.Geo ., as a Qualified Person in accordance with the standards of NI 43-101 in the 2011 Pirquitas Technical Report. The Mineral Resources estimate of the Cortaderas Area was completed byJeremy D. Vincent ,P.Geo ., as a Qualified Person in accordance with the standards of NI 43-101. Mineral Resources are reported above a cut-off grade of 50 grams per tonne silver and are reported inclusive of Mineral Reserves. All Measured Mineral Resources are situated in the Mining Area. Indicated Resources in the Mining Area comprise 15.9 million tonnes, totalling 72.8 million ounces of silver. Stockpile material comprises 1.4 million tonnes of mined material, totalling 6.1 million ounces of silver. Inferred Resources in the Mining Area comprise 0.03 million tonnes, totalling 0.1 million ounces of silver. For a complete description of the key assumptions, parameters and methods used to estimate the Mineral Reserves and Mineral Resources, please refer to the 2011 Pirquitas Technical Report.
Pitarrilla
- Mineral Reserve and Mineral Resource estimates are as at
December 4, 2012 and are contained in the 2012 Pitarrilla Technical Report. The Mineral Reserves estimate was completed byAndrew W. Sharp , FAusIMM, as a Qualified Person in accordance with the standards of NI 43-101. The Mineral Reserves estimate uses a NSR calculation to determine cut-off usingUS$25.00 per troy ounce silver,US$0.90 per pound lead andUS$0.95 per pound zinc. The Mineral Reserves contain two ore types-direct leach ore and flotation/leach ore. The constant cut-off value for direct leach ore isUS$16.38 /tonne and for flotation/leach ore isUS$16.40 /tonne. The NSR calculation method varies for the two ore types. For the two ore types combined, the overall average process recovery of silver, lead, and zinc are 69.6%, 57.4%, and 61.3%, respectively. The Mineral Resources estimate is as atDecember 4, 2012 , was completed byJeremy D. Vincent ,P.Geo ., as a Qualified Person in accordance with the standards of NI 43-101. Mineral Resources are reported above a cut-off grade of 30 grams per tonne silver and are reported inclusive of Mineral Reserves. No mining activity has occurred on the property fromDecember 4, 2012 toDecember 31, 2012 . Silver (Ag) was estimated using Localised Uniform Conditioning (LUC). Lead (Pb) and Zinc (Zn) were estimated using Ordinary Kriging (OK).
- Mineral Reserve and Mineral Resource estimates are as at
