Silver Standard Reports Second Quarter 2017 Production Results

VANCOUVER, July 12, 2017 /PRNewswire/ - Silver Standard Resources Inc. (NASDAQ: SSRI) (TSX: SSO) ("Silver Standard") reports second quarter 2017 operating results at our three mines.

Second Quarter 2017 Operating Highlights

• Continued strong production growth: Quarterly attributable production exceeded 100,000 gold equivalent ounces from three operations.
  
  
• Increased tonnage at Marigold: Mined 18.0 million tonnes and stacked 6.9 million tonnes of ore, both a quarter-on-quarter increase.
  
  
• Gold production at Marigold to plan: Produced 55,558 ounces of gold during the second quarter of 2017.
  
  
• Higher mill throughput at Seabee: Record monthly ore milled at approximately 1,050 tonnes per day in June 2017, supporting strong quarterly mill ore tonnage of 928 tonnes per day.
  
  
• Robust gold production at Seabee: Produced 20,690 ounces of gold during the second quarter of 2017.
  
  
• Exceeded planned operating performance at Pirquitas: The mill continued to operate at a rate of approximately 5,000 tonnes per day. Combined with higher than expected grades within the stockpiles, this contributed to total silver production of 1.9 million ounces during the second quarter, 28% higher than the first quarter.

Paul Benson, President and CEO said, "During the second quarter of 2017 all three mines demonstrated strong operating performance, resulting in over 100,000 gold equivalent ounces of production. Both Marigold and Seabee mined more total material compared to the previous quarter and Seabee continued to demonstrate its ability to process ore at improved daily throughput, achieving approximately 1,050 tonnes per day in the month of June. With this strong operating performance, we are well-positioned for the year and for continued growth."

Marigold Mine, U.S.

In the second quarter of 2017, the Marigold mine produced 55,558 ounces of gold, in line with the previous quarter production. Gold sales totaled 57,426 ounces for the quarter including inventory from the first quarter.

A total of 18 million tonnes were mined in the second quarter of 2017, 7.5% more than the first quarter of 2017, primarily due to improved weather conditions. Approximately 6.9 million tonnes of ore were delivered to the heap leach pads at an average gold grade of 0.31 g/t as we completed the current mining phase at the Mackay pit. This compares to 5.7 million tonnes of ore delivered to the heap leach pads at a gold grade of 0.42 g/t in the first quarter of 2017.  Gold grade mined in the second quarter was 26% lower than the first quarter due to planned pit phase sequencing and mining a higher amount of lower-grade ore as we completed the deeper phase of the Mackay pit.  The strip ratio declined to 1.60:1 in the quarter, an 18% reduction compared to the previous quarter.

Seabee Gold Operation, Canada                                                                                                        

In the second quarter of 2017, the Seabee Gold Operation produced 20,690 ounces of gold. Gold sales were 17,909 ounces for the second quarter, reflecting an increase in bullion inventory.

A near-quarterly record 84,469 tonnes of ore was milled at an average gold grade of 7.97 g/t during the second quarter of 2017. This compares to a total of 72,394 tonnes of ore at an average grade of 9.22 g/t in the first quarter. Ore was mined at both the Santoy and Seabee mines with lower grade ore at Seabee reducing the overall average mill grade during the second quarter. The Santoy mine complex supplied 76% of ore milled, predominantly from long hole stopes. Gold recovery remained relatively consistent at 97.3% in the current quarter. The ventilation system upgrade project is on schedule to be completed in July 2017.

Stope production at Santoy was impacted by a fall of ground early in the second quarter. While there were no injuries to people or damage to equipment, restrictions were put in place until a full review of the ground support in the area was completed. These self-imposed restrictions had the effect of reducing tonnage and grade to the plant during the quarter. Following modifications to the support design and installation, production from Santoy returned to planned levels in June.

During the second quarter, the mill achieved an average throughput of 928 tonnes per day, 15% higher than the previous quarter, with a record 1,049 tonnes per day milled in the month of June, as the mines focused on Operational Excellence initiatives to deliver and process more ore tonnage.

Puna Operations, Argentina¹

The operation produced a total of 1.9 million ounces of silver from processing of stockpiles, a 28% increase compared to the first quarter of 2017. Silver sales were 1.7 million ounces for the quarter.

Ore was milled at an average rate of 4,903 tonnes per day in the second quarter, 23% above the mill's nominal throughput of 4,000 tonnes per day. Ore milled in the second quarter of 2017 contained an average silver grade of 185 g/t, 28% higher than the 145 g/t reported in the first quarter of 2017 due to better than expected grades in the stockpiles. The average silver recovery in the second quarter was 73.5%, higher than the 72.6% recovery in the previous quarter, in line with the higher silver mill feed grade.

Silver Standard finalized its joint venture to combine the Pirquitas mine with the Chinchillas project on May 31, 2017. The joint venture, named Puna Operations Inc., is comprised of Silver Standard's Pirquitas property and Golden Arrow Resources' Chinchillas property and is owned on a 75%/25% basis by each company, respectively. We are the joint venture operator. As a result of the joint venture, our attributable share of production in the second quarter was 1.8 million ounces of silver and attributable sales were 1.5 million ounces.

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.
