SSR Mining Inc. has released the second quarter 2018 operating results at its three mines.

Second quarter 2018 operating highlights:

• Increased production at Marigold: produced 49,436 ounces of gold, an increase of 15 per cent compared with the first quarter;
• Record ore tonnes stacked at Marigold: stacked a record 7.9 million tonnes of ore at an increased grade of 0.42 gram per tonne (g/t);
• Production in line with guidance at Seabee: produced 23,582 ounces of gold, with all ore sourced from the high-grade Santoy mine;
• Strong quarterly production at the Puna operations: produced 1.0 million ounces of silver, for a total of 1.9 million ounces of silver produced in the first half of 2018, exceeding guidance.

Paul Benson, president and chief executive officer, said: "Solid performance at each of our operations in the second quarter keeps us well on track for full-year production guidance. With a stronger second half of the year still in front of us, we look forward to delivering into near-term growth."

In the second quarter of 2018, the Marigold mine produced 49,436 ounces of gold, a 15-per-cent increase over the first quarter. Gold sales totalled 46,644 for the quarter, reflecting an increase in bullion inventory.

During the quarter, 16.0 million tonnes of material were mined, similar to the first quarter, primarily due to longer haul distances associated with the increase in ore tonnes. SSR Mining expects total material mined to increase during the second half of 2018, due to shorter haul distances and as the four additional haul trucks enter service. These factors, along with completion of the new leach pad, are expected to increase gold production through the second half of the year.

Approximately 7.9 million tonnes of ore were delivered to the heap leach pads, a quarterly record. Gold grade increased to 0.42 g/t. This compares with 7.1 million tonnes of ore delivered to the heap leach pads at a gold grade of 0.37 g/t in the first quarter of 2018. The strip ratio was 1.0:1 for the quarter, 23 per cent lower than the prior quarter.

Beginning with the first quarter of 2018, the 
holder of a 3-per-cent net smelter returns (NSR)
royalty elected to receive its royalty in kind, 
and the company will no longer report these 
ounces within gold sold.

The Seabee gold operation produced 23,582 ounces of gold in the second quarter, in line with production in the previous quarter. Gold sales were 20,500 ounces, lower than production as gold ounces poured at the end of the second quarter will be sold in the third quarter.

The mill achieved an average throughput of 923 tonnes per day, an 11-per-cent decrease from the first quarter. Production during the second quarter was impacted by planned maintenance, the transition of mining activities to the high-grade Santoy mine and a forest fire. Mill throughput is expected to increase through the second half of the year relative to the second quarter. Gold recovery for the quarter remained consistent at 97.3 per cent.

Notes:

(1) Figures are on a 100-per-cent basis unless 
otherwise noted.

(2) Data for zinc production and sales relate 
only to zinc in zinc concentrate. 

(3) Figures are on a 75-per-cent attributable 
basis.                                                                                                                       

During the second quarter of 2018, the Puna operations produced 1.0 million ounces of silver, for a total of 1.9 million ounces produced in the first half of 2018, exceeding SSR Mining's silver production guidance of 1.6 million ounces. Silver sales were 1.1 million ounces for the quarter, as concentrate inventories were further reduced. SSR Mining's attributable share of silver production and sales in the second quarter were 700,000 ounces and 900,000 ounces, respectively.

Ore was milled at an average rate of 4,353 tonnes per day in the second quarter, 5 per cent above the previous quarter. Ore milled in the second quarter contained an average silver grade of 110 g/t, 4 per cent lower than the average silver grade of 115 g/t in the first quarter, consistent with processing of increasingly lower-grade stockpiles. The average silver recovery in the second quarter was 64 per cent, 6 per cent lower than the previous quarter.

SSR Mining commenced production of zinc concentrate from stockpiles later in the second quarter and produced approximately 1.5 million pounds of zinc. No zinc sales occurred during the quarter.
