Silver Standard Reports First Quarter 2017 Production Results

VANCOUVER, April 11, 2017 /PRNewswire/ - Silver Standard Resources Inc. (NASDAQ: SSRI) (TSX: SSO) ("Silver Standard") reports first quarter 2017 operating results at our three mines.

First Quarter 2017 Operating Highlights

• Consistent production scale: Produced 97,851 gold equivalent ounces from three operations in the first quarter of 2017.
  
  
• Gold production at Marigold to plan: Produced 55,215 ounces of gold during the first quarter of 2017.
  
  
• Robust gold production at Seabee: Achieved production of 21,023 ounces of gold in the first quarter of 2017 as higher grade ore was sourced from the Santoy mine.
  
  
• Strong operating fundamentals at Pirquitas: The operation concluded open pit mining in January 2017 and commenced stockpile processing, taking quarterly production to 1.5 million ounces of silver. The mill continued to operate at a rate of approximately 5,000 tonnes per day, 25% above nominal throughput.

Paul Benson, President and CEO said, "Our production of 97,851 gold equivalent ounces is a strong start to the year, highlighted by Seabee continuing to demonstrate a capability to produce above historical levels. The sustained contribution from all three of our assets was solidified by our recent announcement to exercise our option on the Chinchillas project to extend the operating life of Pirquitas. This, combined with our focus on safe production and operational excellence, demonstrates the success of our strategy to create value through internal and external opportunities."

Marigold mine, U.S.

In the first quarter of 2017, the Marigold mine produced 55,215 ounces of gold, in line with plan. Gold sales totaled 52,528 ounces for the quarter.

A total of 16.7 million tonnes were mined in the first quarter of 2017, 14% less than the fourth quarter of 2016, primarily due to weather-related impacts in January and February, which caused the open pit to cease operations intermittently due to unsafe work conditions.  Additionally, the rope shovel was down for planned maintenance for five days during the month of March. Approximately 5.7 million tonnes of ore were delivered to the heap leach pads at an average gold grade of 0.42 g/t. This compares to 6.4 million tonnes of ore delivered to the heap leach pads at a gold grade of 0.48 g/t in the fourth quarter of 2016. Gold grade mined in the first quarter was 13% lower than the fourth quarter due to planned pit phase sequencing. The strip ratio declined to 1.95:1 in the quarter, a 4% reduction compared to the previous quarter.

Seabee Gold Operation, Canada

In the first quarter of 2017, the Seabee Gold Operation produced 21,023 ounces of gold, a 7% increase from the 19,711 ounces of gold produced during the fourth quarter of 2016, primarily due to higher grade ore from the Santoy mine complex. Gold sales were 22,411 ounces for the quarter, including inventory carried over from the fourth quarter of 2016.

A total of 72,394 tonnes of ore was milled at an average gold grade of 9.22 g/t and recovery of 97.7% during the first quarter of 2017. This compares to a total of 84,526 tonnes of ore milled at an average gold grade of 7.40 g/t and recovery of 97.0% in the fourth quarter of 2016.

During the first quarter, the mill was maintained at a throughput of 804 tonnes per day, lower than the previous quarter as ore delivery constrained mill throughput due to ventilation system limitations. Additional fans and electrical equipment were delivered to the mine and are expected to be operational by mid-year. The Santoy mine complex supplied 98% of ore milled in the first quarter, predominantly from long hole stopes. We continue to develop new mine plans to determine a higher, sustainable production rate.

Pirquitas mine, Argentina

Mining from the San Miguel open pit ceased in January 2017 and medium grade stockpile material is being processed through the plant. Lower grade stockpiles may be processed in late 2017, and potentially in early 2018, once the medium grade stockpiles have been consumed, depending on prevailing economic conditions.

The operation produced a total of 1.5 million ounces of silver from ore mined and stockpiles processed. Silver sales were 1.4 million ounces for the quarter.

Ore was milled at an average rate of 4,994 tonnes per day in the fourth quarter, 25% above the mill's nominal throughput of 4,000 tonnes per day. Ore milled in the first quarter of 2017 contained an average silver grade of 145 g/t, 25% lower than the 194 g/t reported in the fourth quarter of 2016 as the majority of mill feed was sourced from medium grade stockpile ore. The jig circuit is not utilized to treat stockpile material. The average silver recovery in the first quarter was 72.6%, lower than the 74.5% recovery in the previous quarter, in line with reduced silver mill feed grade.

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. These standards differ significantly from the requirements of the SEC set out in SEC Industry Guide 7. Consequently, Mineral Reserves and Mineral Resources information included in this news release is not comparable to similar information that would generally be disclosed by domestic U.S. reporting companies subject to the reporting and disclosure requirements of the SEC. Under SEC standards, mineralization may not be classified as a "reserve" unless the determination has been made that the mineralization could be economically produced or extracted at the time the reserve determination is made. Moreover, the requirements of NI 43-101 for identification of "reserves" are also not the same as those of the SEC, and reserves reported by us in compliance with NI 43-101 may not qualify as "reserves" under SEC standards. Accordingly, information concerning mineral deposits set forth herein may not be comparable with information made public by companies that report in accordance with U.S. standards.
