VANCOUVER, BRITISH COLUMBIA--(Marketwire - Feb. 27, 2012) - Silver Standard Resources Inc. (News - Market indicators)(NASDAQ:SSRI) ("Silver Standard" or the "Company") announced today an update for the Pitarrilla project in Durango, Mexico ("Pitarrilla"), including an updated mineral resources estimate for oxide and sulphide mineralization.

Highlights

• Contracted M3 Engineering to complete the Pitarrilla feasibility study. M3 has designed and built many mines in Mexico, including the Peñasquito mine.
• Feasibility study on track for mid-year 2012 completion.
• Construction permit application on track for second-half 2012 submission.
• Feasibility design is being based on an open-pit mine and a 16,000 tonne per day plant with an agitated leach circuit producing a silver doré and a flotation circuit producing separate zinc and lead concentrates containing payable silver.
• Hired experienced project manager and key development and construction management personnel.
• Measured and Indicated mineral resources estimate of 655.7 million ounces of contained silver (at a 30 g/t silver cut-off grade).
• Inferred mineral resources estimate of 65.0 million ounces of contained silver (at a 30 g/t silver cut-off grade).

"Pitarrilla's mineral resources are significant and drive the potential for a long-life mine with strong annual silver production," said John Smith, President and CEO. "Our team has now settled on an open-pit design concept to optimize a larger amount of silver for the long-term benefit of our shareholders and stakeholders. This approach is consistent with our positive outlook on silver and our strategy of driving growth and value from our extensive 100% owned asset portfolio."

The Pitarrilla feasibility study is being prepared by M3 Engineering & Technology Corporation and the Company's development team, and will build on previous resource engineering and design work. This Pitarrilla feasibility study will focus on mining oxide and sulphide ores from one large open-pit operation. Plant facilities are expected to target 16,000 tonnes per day and include a milling circuit, an agitated leach circuit and a flotation circuit. These facilities are expected to produce silver doré, and separate zinc and lead concentrates containing payable silver. Completion of the Pitarrilla feasibility study is scheduled for mid-year 2012.

A diamond drill program of approximately 8,300 meters is scheduled for 2012, with the objective of expanding the near-surface oxide mineralization at the Breccia Ridge and South Ridge zones. In addition, metallurgical testing is underway to optimize metal recoveries from oxide and sulphide mineralization. Where possible, results of this year's drilling and metallurgical studies will be included in the Pitarrilla feasibility study.

The January 31, 2012, Pitarrilla mineral resources estimate was prepared, verified and approved by the Company's qualified person Dr. Warwick Board, Ph.D., Senior Geologist with Silver Standard. The estimate is presented at three different silver cut-off grades in Table 1, shown below. These mineral resources estimates are not materially different from those previously published. A new mineral reserve estimate will be prepared as part of the Pitarrilla feasibility study. This new mineral reserve estimate will utilize the open-pit mine concept whereas the current mineral reserve estimate utilizes an underground mine concept.

Table 1. Pitarrilla Mineral Resources Estimate (effective as of January 31, 2012)

Notes to Table 1:

1. Dr. Warwick Board, Ph.D. (Geology), P.Geo., is the Qualified Person for the reported mineral resources estimate.
2. All mineral resources have been classified in accordance with current CIM definition standards.
3. The Ordinary Kriging with appropriate top-cuts modeling methodology was employed for the mineral resources estimates presented in the above table.
4. Although a silver cut-off grade of 30 g/t Ag is considered at this time to be the most likely economic cut-off grade for large-scale open-pit mining of the Pitarrilla deposit, it has not yet been confirmed by the appropriate mining studies. A detailed economic cut-off grade analysis will be conducted as part of the Pitarrilla feasibility study.
5. Silver capping grades used in the estimation range between 415 g/t Ag and 1,825 g/t Ag for the various oxide domains, and between uncapped to 1,370 g/t Ag for the various sulphide domains. Zinc capping grades used in the estimation range between 0.55% Zn and 4.63% Zn for the various oxide domains, and between uncapped and 10.00% Zn for the various sulphide domains. Lead capping grades used in the estimation range between uncapped and 4.02% Pb for the various oxide domains, and between uncapped and 6.04% Pb for the various sulphide domains.
6. Detailed bulk density modeling was conducted taking into account lithological variability (including an analysis of voids), mineralization, and degree of oxidation.
7. The drillhole database including collar, survey, assay, lithology, and mineralization, used in the preparation of the mineral resources estimate in Table 1 was validated through conducting detailed verification checks, including QA/QC of location and assay data.
8. Sums may not equal reported totals due to rounding.
