VANCOUVER, Jan. 14, 2015 /PRNewswire/ - Silver Standard Resources Inc. (SSRI) (SSO.TO) ("Silver Standard") reports its fourth quarter and full year 2014 operational results, with both Marigold and Pirquitas exceeding 2014 production guidance. In addition, we are providing production and cost guidance for 2015.

Fourth Quarter and 2014 Operating Highlights:

Pirquitas                                                                        

• Record annual silver and zinc production: Produced 8.7 million ounces of silver in 2014, including 2.2 million ounces in the fourth quarter. Achieved production guidance for the third consecutive year demonstrating consistent delivery to plan. The mine also had record annual zinc production of 30.0 million pounds in 2014.
  
  
• Strong fourth quarter sales: Silver sales of 2.8 million ounces and zinc sales of 8.7 million pounds in the fourth quarter, reducing inventory levels as planned.

Marigold

• Record fourth quarter gold production: Produced 129,615 ounces of gold from April to December 2014, exceeding our 2014 production guidance which had been previously increased to between 110,000 and 120,000 ounces. Produced 67,113 ounces in the fourth quarter, a quarterly record for the mine since it commenced production in 1988 and 66% higher than the previous quarter.
  
  
• Exploration program delivers: 2014 drill program adds higher grade Mineral Resources to the 8 South pit area. The extension to the 8 South pit currently contains Indicated Mineral Resources of 82,000 ounces of gold at a grade of 1.20 grams per tonne and Inferred Mineral Resources of 75,000 ounces of gold at a grade of 1.41 grams per tonne, as reported in our release dated December 12, 2014.

"The strong fourth quarter performance at both mines capped a transformative year for Silver Standard," said John Smith, President and CEO. "The team's discipline and focus on operational excellence is evident, as demonstrated by our production of 6.9 million silver equivalent ounces in the fourth quarter. The acquisition of the Marigold mine and strong operating and cost performance at both mines positions us with two cash-flowing assets, capable operating teams and a robust balance sheet to drive further value and growth in 2015."

Pirquitas mine, Argentina

The Pirquitas mine produced 2.2 million ounces of silver during the fourth quarter of 2014, lower than the 2.6 million ounces produced in the third quarter of 2014 due to slightly lower ore milled and mill feed silver grades, which were partially offset by improved recoveries. Mill feed in the fourth quarter was solely from ore mined from the open pit in the period while third quarter silver production benefited from previously mined higher grade stockpiled material. Silver sales totaled 2.8 million ounces for the quarter, a 49% increase from the third quarter, as higher scheduled shipments reduced inventory levels.

During 2014, the mine produced record 8.7 million ounces of silver, exceeding the higher end of our 8.2 to 8.6 million ounces of silver production guidance range and higher than the 8.2 million ounces produced in 2013. Silver shipments totaled 8.6 million ounces with sales of 8.1 million ounces for the year. Silver sales are below silver production due to timing of shipments.

In 2014, Pirquitas produced 30.0 million pounds of zinc in zinc concentrate, a record for the mine, reflecting higher zinc grades as we mined more of the zinc-rich Potosi area of the San Miguel open pit, combined with improved recoveries. The mine produced 4.8 million pounds of zinc in zinc concentrate in the fourth quarter of 2014.

Ore was milled at an average rate of 4,045 tonnes per day in the fourth quarter. The average silver grade of ore milled was 222 g/t, slightly lower than the 248 g/t reported in the third quarter which benefited from previously mined higher grade stockpiled material. The average recovery rate for silver in the fourth quarter increased to 83.8% from 78.7% in the previous quarter as the mill processed fresh sulphide feed from the open pit and process control improvements positively impacted plant operating performance. Zinc recovery to zinc concentrate was 53%, representing a 21% improvement over the previous quarter, achieved despite a drop in zinc head grade.

Marigold mine, U.S.

The Marigold mine produced 67,113 ounces of gold during the fourth quarter, significantly higher than the third quarter production of 40,442 ounces of gold and 22% higher than the upper end of our quarterly guidance range. As planned, mined material through late third quarter and in the fourth quarter was primarily from the higher grade lower benches of the Mackay Phase 1 pit, leading to increased ounces stacked on the leach pads through this period. Gold sales totaled 68,748 ounces for the quarter.

Gold production attributed to Silver Standard for the nine months ending December 2014 totaled 129,615 ounces, which exceeded the high end of our increased production guidance range of between 110,000 and 120,000 ounces for that period. Gold sales were 128,983 ounces during the same period.

A total of 18.4 million tonnes of material were mined in the fourth quarter of 2014, compared to 18.8 million tonnes mined in the third quarter. Approximately 3.8 million tonnes of ore were delivered to the heap leach pads at a grade of 0.84 g/t gold, which represents approximately 75,600 recoverable ounces of gold stacked during the quarter. This compares to 5.0 million tonnes of ore delivered to the heap leach pads at a grade of 0.53 g/t gold in the third quarter of 2014, which represents approximately 62,500 recoverable ounces of gold. Grade mined in the fourth quarter was 59% higher than the third quarter. Stripping of the next phase of the Mackay pit commenced in the fourth quarter, leading to an expected increase in strip ratio in the quarter.

2015 Outlook

For the full year 2015, we expect:

At the Pirquitas mine silver production is expected to increase over 2014 as mining progresses through the higher grade portions of the San Miguel Phase 2 open pit with stable cash costs per payable ounce sold. Capital expenditures of $10 million consist principally of mine and plant capital spares and initial work on the stage 5 tailings dam.

Our gold production from Marigold is expected to increase due to full year ownership of the asset. Production is expected to be strongest in the first and fourth quarters of the year as a strong end to 2014 carries into the first quarter of 2015 and mining progresses into lower areas of the next phase of the Mackay pit later in the year. Capital expenditures of $20 million include approximately $7 million for cell 20 leach pad construction, $9 million for maintenance and capitalized spares for mining equipment and $2 million for capitalized exploration drilling.

Exploration and development expenditures are forecast to remain at a reduced level of $15 million for 2015. Planned expenditures include $4 million on drilling proximate to the Pirquitas mine and $3.5 million of expensed exploration at Marigold. Property holdings are being maintained in good standing with limited activities expected at Pitarrilla while spending at San Luis is conditional upon successful community agreements.

Cautionary Note to U.S. Investors

This news release includes Mineral Reserves and Mineral Resources classification terms that comply with reporting standards in Canada and the Mineral Reserves and the Mineral Resources estimates are made in accordance with NI 43-101. NI 43-101 is a rule developed by the Canadian Securities Administrators that establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects.
