SILVER STANDARD REPORTS SECOND QUARTER 2017 PRODUCTION RESULTS

Silver Standard Resources Inc. has released second quarter 2017 operating results at its 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 per cent higher than the first quarter.

Paul Benson, president and chief executive officer, 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."

In the second quarter of 2017, the Marigold mine produced 55,558 ounces of gold, in line with the previous quarter production. Gold sales totalled 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 per cent 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 gram per tonne as we completed the current mining phase at the Mackay pit. This compares with 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 per cent lower than the first quarter due to planned pit phase sequencing and mining a higher amount of lower-grade ore as the company completed the deeper phase of the Mackay pit. The strip ratio declined to 1.60 to 1 in the quarter, an 18-per-cent reduction compared with the previous quarter.

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 were milled at an average gold grade of 7.97 g/t during the second quarter of 2017. This compares with 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 per cent of ore milled, predominantly from long-hole stopes. Gold recovery remained relatively consistent at 97.3 per cent 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 per cent 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.

The operation produced a total of 1.9 million ounces of silver from processing of stockpiles, a 28-per-cent increase compared with 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 per cent 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 grams per tonne, 28 per cent 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 per cent, higher than the 72.6 per cent 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 composed of Silver Standard's Pirquitas property and Golden Arrow Resources' Chinchillas property and is owned on a 75-per-cent/25-per-cent basis by each company, respectively. Silver Standard is the joint venture operator. As a result of the joint venture, the company's attributable share of production in the second quarter was 1.8 million ounces of silver, and attributable sales were 1.5 million ounces.
