SSR MINING REPORTS FIRST QUARTER 2018 PRODUCTION RESULTS

VANCOUVER, B.C. – SSR Mining Inc. (NASDAQ: SSRM) (TSX: SSRM) (“SSR Mining”) reports

first quarter 2018 operating results at our three mines.

First Quarter 2018 Operating Highlights

 Production in line with guidance at Marigold: Produced 42,960 ounces of gold and stacked

a near-record 7.1 million tonnes of ore during the quarter.

 Record quarterly throughput at Seabee: Achieved record mill throughput of 93,269 tonnes,

or 1,036 tonnes per day, for 23,717 ounces of gold production.

 Solid quarterly production at Puna Operations: Produced 0.9 million ounces of silver as

performance from stockpiles continued to exceed expectations.

Paul Benson, President and CEO said, “Each of our operations performed well during the quarter.

Particularly pleasing was the continued increase in mill throughput at Seabee where our ongoing

Operational Excellence initiatives have seen mill throughput and gold production continue to rise

since we acquired the mine in 2016.”

In the first quarter of 2018, the Marigold mine produced 42,960 ounces of gold, in line with

guidance expectations. Production was 19% less than the previous quarter, due to lower ore

stacked in the fourth quarter of 2017. Gold sales totaled 42,078 ounces for the quarter.

During the quarter, 16.2 million tonnes of material were mined, 16% more than the fourth quarter

of 2017, reflecting an increase in operating days for the quarter due to a resumption of normal

mining activities. We expect quarterly material movement to increase in the second quarter of

2018, and further in the second half of the year as four additional haul trucks are added to the

fleet. Approximately 7.1 million tonnes of ore were delivered to the heap leach pads at an average

gold grade of 0.37 g/t. This compares to 5.8 million tonnes of ore delivered to the heap leach pads

at a gold grade of 0.37 g/t in the fourth quarter of 2017. The strip ratio was 1.3:1 for the quarter,

a 7% decrease compared to the previous quarter.

(2) Beginning with the first quarter of 2018, the holder of a 3% net smelter returns royalty elected to receive its royalty in-kind and

we will no longer report these ounces within gold sold.

In the first quarter of 2018, Seabee Gold Operation produced 23,717 ounces of gold. With the

commissioning of the new gravity circuit at the end of the quarter, in circuit gold inventory

increased by approximately 2,400 ounces of gold, which is expected to positively impact gold

production through the remainder of 2018. Gold sales were 20,012 ounces, lower than gold

production due to bullion inventory increasing relative to the previous quarter.

During the first quarter, total ore milled increased 5% over the previous quarter, with the Santoy

mine supplying 73% of ore milled. Following an extensive underground exploration program, ore

extraction at the Seabee mine completed during the first quarter and it is currently undergoing

decommissioning in advance of closure later this year. Going forward, all ore will be sourced from

the Santoy mine.

The mill achieved an average throughput of 1,036 tonnes per day during the quarter, 7% higher

than the previous quarter due to a combination of Operational Excellence initiatives at both the

mill and the Santoy mine. Gold recovery remained consistent at 97.4%.

(3) Percent changes are calculated using rounded numbers presented in the table.

During the first quarter of 2018, the operation produced 0.9 million ounces of silver, in line with

expected silver production from stockpiles of 1.6 million ounces in the first half of 2018. Silver

sales were 1.1 million ounces for the quarter as concentrate inventories were reduced. Our

attributable share of silver production and sales in the third quarter was 0.7 million ounces and

0.8 million ounces, respectively.

Ore was milled at an average rate of 4,144 tonnes per day in the first quarter, 14% below the

previous quarter. Crusher operations in the first quarter were constrained by construction of the

crushed ore stockpile dome and wetter than normal weather conditions. Ore milled in the first

quarter of 2018 contained an average silver grade of 115 g/t, 8% lower than the 125 g/t reported

in the fourth quarter of 2017 as we process increasingly lower grade stockpiles. The average

silver recovery in the third quarter was 67.7%, marginally above the previous quarter.

Partial Disposal of Pretium Common Shares

During the first quarter, we sold 4.0 million common shares of Pretium Resources Inc. (“Pretium”),

realizing pre-tax net cash proceeds of C$35.1 million. At quarter end, we held 5.0 million common

shares, representing approximately 2.8% of Pretium.
