SSR MINING REPORTS FIRST QUARTER 2019 PRODUCTION RESULTS

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

first quarter 2019 operating results at our three mines.

First Quarter 2019 Operating Highlights

▪ Achieved strong consolidated production: Produced over 112,000 gold equivalent ounces

in the first quarter of 2019.

▪ Record quarterly gold production at Seabee: Produced 31,183 ounces of gold due to

higher mill throughput and timing of gold pours, representing a quarter-on-quarter increase of

52%.

▪ Solid operating performance at Marigold: Mined 17.3 million tonnes of material while gold

production remained strong at 53,151 ounces.

▪ Silver production doubled at Puna Operations: Produced 2.4 million ounces of silver ,

double the silver production in the fourth quarter of 2018, with lead and zinc production of 6.8

million pounds and 1.6 million pounds, respectively. Ramp up at the Chinchilla s mine was

substantially completed during the quarter.

Paul Benson, President and CEO said, “It is pleasing to have a good start to the year with a near-

record consolidated gold equivalent production of over 112,000 ounces, highlighted by quarterly

record gold production at Seabee, where we continue to achieve higher mill throughput rates. The

Chinchillas project was substantially completed during the quarter, setting us up for steady state

production at Puna Operations. With all three operations performing well, we are positioned to

achieve record production in 2019.”

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

In the first quarter of 2019, the Marigold mine produced 53,151 ounces of gold, a 2% decline from

the fourth quarter mainly due to weather conditions during the period. Gold sales totaled 55,517

ounces, 10% higher than the previous quarter as we sold bullion inventory accumulated in the

fourth quarter of 2018.

During the quarter, 17.3 million tonnes of material were mined, a 2% increase compared to the

fourth quarter of 2018, as we commenced mining the next phase of the Mackay pit, which resulted

in shorter haul distances and offset the weather events early in the quarter.

Approximately 5.5 million tonnes of ore were delivered to the heap leach pads at a grade of 0.34

g/t gold. This compares to 5.7 million tonnes of ore delivered to the heap leach pads at a grade

of 0.34 g/t gold in the fourth quarter of 2018. The strip ratio was 2.1:1 for the quarter.

Notes:

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

Seabee Gold Operation produced a record 31,183 ounces of gold in the first quarter of 2019 ,

largely due to timing of gold pours at year-end and aided by increased mill throughput rate. Gold

sales totaled 27,999 ounces for the first quarter, 29% higher than the fourth quarter of 2018.

The mill achieved an average throughput of 1 ,008 tonnes per day over the first quarter , a 7%

increase compared to the previous quarter , and 1,079 tonnes per day for the month of March,

both reflecting a higher mining rate at the Santoy mine. Gold mill feed grade was 8.59 g/t, in line

with plan. Gold recovery remained consistent at 97.2%.

(5) Data for lead production and sales relate only to lead in lead concentrate.

The Chinchillas mine ramp up was substantially completed during the first quarter of 2019. Total

material mined from the Chinchillas open pit increased significantly compared to the previous

quarter as commercial production was achieved on December 1, 2018. The strip ratio during the

first quarter was 16.5:1 due to commencing a new pushback at the Chinchillas pit as planned.

Silver production was 2.4 million ounces for the quarter, an increase of 101% relative to the fourth

quarter of 2018, mainly due to higher silver mill feed grade and silver recovery, as ore was sourced

exclusively from the Chinchillas mine. Silver sales totaled 0.9 million ounces as concentrate

shipments commenced later in the quarter. On an attributable basis, silver production and sales

for the first quarter totaled 1.8 million ounces and 0.7 million ounces, respectively.

During the first quarte r, ore was milled at an average of 3,830 ton nes per day, a 3% in crease

compared to ore milled in the previous quarter, mainly due to improvements in mill flotation

pumping. Processed ore in the first quarter of 2019 contained an average silver grade of 235 g/t,

a 77% increase compared to the fourth quarter of 2018, due to solely processing higher grade

Chinchillas ore. Metallurgical recoveries of silver, lead and zinc are expected to be variable until

we achieve stead y state production. The new tailings pump system at the Pirquitas plant was

completed during the quarter.
