SSR MINING REPORTS THIRD QUARTER 2017 PRODUCTION RESULTS

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

third quarter 2017 operating results at our three mines.

Third Quarter 2017 Operating Highlights

 Strong gold sales at Seabee: Sales of 21,798 ounces of gold in the quarter from bullion

inventory and solid gold production from sustained daily throughput and recovery rates.

 Record quarterly material moved at Marigold: Mined over 20 million tonnes of material

during the quarter. As expected, third quarter production was lower than the previous quarter

at 38,699 ounces of gold.

 Achieved annual production guidance at Puna Operations: The Pirquitas mill operated at

a rate of approximately 5,000 tonnes per day, which drove production of 1.5 million ounces of

silver during the quarter and 5.0 million ounces year-to-date, surpassing the lower end of

annual production guidance.

Paul Benson, President and CEO said, “In the third quarter, all three operations had record or

near-record operating achievements, which is particularly notable at Seabee as the mine was

impacted for a significant part of the quarter by nearby forest fires. With Marigold mining through

a low-grade portion of the orebody this year and Puna Operations processing stockpiles, the focus

on operating performance is paramount and drives the sustained performance and growth from

our portfolio. We anticipate strong operating performance in the fourth quarter to round out a

successful year for SSR Mining.”

Notes:

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

In the third quarter of 2017, the Marigold mine produced 38,699 ounces of gold, 30.3% less than

the previous quarter due to continued lower grades of ore stacked as we began mining the upper

benches of the current phase of the Mackay pit. Gold sales totaled 38,818 ounces for the quarter.

A quarterly record of 20.3 million tonnes of material were mined in the third quarter of 2017, 13%

more than the second quarter of 2017 , primarily due to planned shorter hauls for waste.

Approximately 7.2 million tonnes of ore were delivered to the heap leach pads at an average gold

grade of 0.31 g/t. This compares to 6.9 million tonnes of ore delivered to the hea p leach pads at

a gold grade of 0.31 g/t in the second quarter of 2017. The strip ratio was 1.8:1 for the quarter, a

13% increase compared to the previous quarter.

Notes:

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

In the third quarter of 2017, the Seabee Gold Operation produced 18,058 ounces of gold, a strong

result considering several operating interruptions. Gold sales were 21,798 ounces for the third

quarter, higher than gold production as bullion inventory accumulated in the previous quarter was

sold in the third quarter.

During the third quarter, 84,315 tonnes of ore were milled at an average gold grade of 7.03 g/t.

This compares to a total of 84,469 tonnes of ore at an average grade of 7.97 g/t in the second

quarter. The Santoy mine supplied 85% of ore milled, predominantly from long hole stopes.

Underground mining activities at Santoy experienced operating interruptions during the third

quarter as a result of forest-fire-related power outages and smoke ingress.

The mill achieved an average throughput of 916 tonnes per day during the quarter, 1.3% lower

than the previous quarter due to a combination of scheduled crusher maintenance activities and

forest-fire-related power outages. Gold recovery remained consistent at 97.2% in the third quarter.

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

During the first nine months of 2017, the operation produced a total of 5.0 million ounces of silver,

surpassing the lower end of our improved 2017 production guidance as stockpile grades and

metallurgical performance continued to exceed plan. In the third quarter of 2017, silver production

from stockpiles totaled 1.5 million ounces. Silver sales were 2.1 million ounces for the quarter.

Attributable share of silver production and sales in the third quarter were 1.2 million ounces and

1.6 million ounces, respectively.

Ore was milled at an average rate of 5,012 tonnes per day in the third quarter, 25% above the

mill’s nominal throughput of 4,000 tonnes per day. Ore milled in the third quarter of 2017 contained

an average silver grade of 153 g/t, 17% lower than the 185 g/t reported in the second quarter of

2017 as we continue to process lower grade stockpiles. The average silver recovery in the third

quarter was 67.8%, lower than the previous quarter as expected due to planned lower silver mill

feed grade.

Partial Disposal of Pretium Common Shares

During the third quarter and subsequent to September 30, 2017, we sold 7.9 million common

shares of Pretium Resources Inc. (“Pretium”) , realizing pre -tax net cash proceeds of C$85.4

million, of which C$70.8 million will be recognized in the third quarter of 2017. We currently hold

9.04 million common shares, representing approximately 4.99% of Pretium.

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 R eserves 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 S EC

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. In addition, the SEC’s disclosure st andards normally do not permit the inclusion of information

concerning “Measured Mineral Resources,” “Indicated Mineral Resources” or “Inferred Mineral Resources”

or other descriptions of the amount of mineralization in mineral deposits that do not constit ute “reserves”

by U.S. standards in documents filed with the SEC. U.S. investors should understand that “Inferred Mineral

Resources” have a great amount of uncertainty as to their existence and great uncertainty as to their

economic and legal feasibility. 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 concern ing mineral deposits set forth

herein may not be comparable with information made public by companies that report in accordance with

U.S. standards.
