SSR MINING ANNOUNCES POSITIVE EXPLORATION RESULTS AT THE AMISK GOLD

PROPERTY IN SASKATCHEWAN

Results Continue to Showcase Prospective Platform in Saskatchewan

DENVER – SSR Mining Inc. (NASDAQ/TSX: SSRM; ASX: SSR) (“SSR Mining” or the “Company”)

is pleased to announce positive exploration results from the Amisk Property in Saskatchewan.

Amisk is located approximately 140 kilometers southeast of the Seabee operation and Fisher

properties and within the prolific Flin Flon mining district (Figure 1). Amisk has many analogous

geological features to the Seabe e/Fisher trend, and reinterpretation of historical data and field

reconnaissance has identified a number of new prospects beyond the existing Amisk deposit.

Field sampling and 10 widely spaced exploration diamond drill holes have confirmed the potential

of the area with significant positive assay results, including:

Black Diamond

• BKD-21-001: 1.51 g/t Au over 6.59 meters from 72.00 meters and 0.84 g/t Au over 9.89

meters from 160.65 meters

• BKD-21-002: 1.16 g/t Au over 6.45 meters from 112.39 meters and 6.15 g/t Au over

2.90 meters from 123.64 meters

• Grab samples up to 83.98 g/t Au

Monarch

• MON-21-002: 1.71 g/t Au over 11.36 meters from 143.03 meters including 6.81 g/t Au

over 1.00 meters

• MON-21-003: 1.27 g/t Au over 10.57 meters from 142.43 meters including 14.13 g/t

over 0.74 meters

• Grab samples up to 20.55 g/t Au

Regional Grab Sample Results

• Raine-Walker: up to 67.15 g/t Au

• TCA: up to 81.59 g/t Au

• Oberon: up to 17.30 g/t Au

• Victory: up to 138.80 g/t Au

Follow up drilling and field work is planned for 2022 , as SSR Mining looks to better define and

potentially expand on the prospective greenfield targets identified on the property to -date. Drill

programs in 2022 will test new targets along the West Channel trend where prospecting and soil

sampling has confirmed significant gold mineralization associated with quartz veins in outcrop.

The Amisk team will also continue evaluating regional data to generate new targets for field

investigation and potential drilling going forward.

The recently announced acquisition of Taiga Gold Corp., including the SAM project that expands

the Amisk Property by 1,004 hectares, reinforces the Company’s commitment to future

exploration across the underexplored and highly prospective province of Saskatchewan.

The Black Diamond Target is located along a folded shear zone northwest of the Amisk deposit

(Figure 4). Drilling is aimed at testing the continuity at depth of broad gold mineralization identified

on surface. Drill intercepts and grab samples at Black Diamond include:

• BKD-21-001: 1.51 g/t Au over 6.59 meters from 72.00 meters and 0.84 g/t Au over 9.89

meters from 160.65 meters

• BKD-21-002: 1.16 g/t Au over 6.45 meters from 112.39 meters and 6.15 g/t Au over

2.90 meters from 123.64 meters

• Grab samples of 83.98 g/t, 41.87 g/t, 30.95 g/t, 21.81 g/t, 21.75 g/t, 20.47 g/t, and 19.03

g/t Au

The West Channel Trend comprises a shear corridor with a defined strike length of > 10 km that

hosts several distinct target areas, including Monarch and Victory (Figure 5). The aim of this

phase of exploration along the West Channel trend was to prove the continuity of mineralization

along strike and to complete an initial phase of drill testing. Drill intercepts and grab samples

along the West Channel include:

• MON-21-001: 0.26 g/t Au over 3.48 meters from 247.71 meters

• MON-21-002: 1.71 g/t Au over 11.36 meters from 143.03 meters including 6.81 g/t Au

over 1.00 meters

• MON-21-003: 1.27 g/t Au over 10.57 meters from 142.43 meters including 14.13 g/t

over 0.74 meters

• Grab samples of 20.55 g/t and 14.41 g/t Au from the Monarch target area

• Grab samples of 138.80 g/t, 61.56 g/t, 41.15 g/t, 31.10 g/t, 29.39 g/t, 13.00 g/t, 12.85

In addition to the Black Diamond and West Channel trends, SSR Mining continues regional

exploration to define and advance targets elsewhere on the property. Select highlights include:

Raine-Walker

• Grab samples of 67.15 g/t, 37.54 g/t, and 11.70 g/t Au

TCA

• Grab samples of 81.59 g/t and 12.21 g/t Au

Oberon

• Grab samples of 17.30 g/t and 13.00 g/t Au

Amisk Property, Saskatchewan

During the summer exploration seasons of 2019, 2020 and 2021, SSR Mining executed

geological mapping, prospecting and soil sampling programs at the Amisk Property located

approximately 140 kilometers southeast of the Seabee operations and Fisher properties (Figure

1). Compilation of historical exploration results indicat ed the presence of regional -scale shear

zones hosting under-explored lode-gold mineralization across the property.

SSR Mining mapped 1,460 hectares during the field programs at a scale of 1:5 ,000, focusing

primarily on the historical gold occurrences associated with regional shear zones. These targets,

such as Black Diamond and West Channel, often measure in the tens of kilometers in length and

are major structural features. SSR Mining collected 4,253 soil samples at a regional spacing of

100 x 25 meters, with more advanced targets receiving detailed (25 x 10 meters) follow up. SSR

Mining prospected and rock sampled along the length of the West Channel and Black Diamond

trends resulting in the discover y of dozens of historical trenches and adits dating back to the

1930s.

Soil samples collected in 2020 and 2021 have identified new gold-in-soil anomalies at the TCA

target and extended existing anomalies along the Black Diamond and West Channel trends. The

combined soil data delineates a pronounced gold-in-soil anomaly at Black Diamond measuring

1,400 by 300 meters with peak values of 945 ppb Au. Along the West Channel the data defines

a near continuous gold -in-soil trend between Monarch and Victory that extends 2,600 meters

along strike and is up to 450 meters wide with peak values of 13,580 ppb Au. At the TCA target,

a gold-in-soil anomaly measuring 750 by 100 m eters has been identified with peak values of

1,490 ppb Au.

The most impressive vein system discovered during fieldwork occurs at the Raine-Walker target

area. The field teams traced a visible-gold bearing quartz vein with true widths up to 4.5 meters

for approximately 400 meters along strike. Assays from grab samp les of this vein peaked with

67.2 g/t and 37.5 g/t gold, with other anomalous results from samples occurring along the length

of the trend. The Raine-Walker area has seen minimal historical drilling and no drill holes proximal

to the high-grade gold occurrences.

SSR Mining initiated its first-ever diamond drill program at the Amisk Property in June 2021 (Table

1). The Black Diamond, Raine-Walker, and Monarch targets were tested by 10 widely spaced,

shallow holes totaling 2,250 meters.

Notes: Intercepts are reported at a cut-off of 0.3 g/t Au with maximum internal dilution of 2.5 meters and a minimum drilled width of

2.5 meters. Internal h igh-grade intervals are reported without a minimum drilled width. Width in meters represents downhole

intersected length, which may or may not be a true thickness of the mineralization. For complete drillhole results for Amisk targe ts

during the exploration period, see Appendix Table 2.

Amisk Overview of Mineralization Style

The West Channel and Black Diamond trends occur along regional -scale ductile shear zones

that range from 5 to 50 meters in orthogonal width. Intermediate volcanic and volcaniclastic rocks

core much of these trends with lesser meta-volcanic, meta-sedimentary and gabbro packages

occurring in proximity to the high -strain corridors. Alteration assemblages of sericite, iron -

carbonate and silicification dominate the regional shear zones. Localized chlorite and diaspore

occurrences are diagnostic and associated with auriferous quartz veins at the Monarch target

area. Arsenopyrite is the most common sulfide mineral associated with this vein-hosted gold

mineralization. Pyrite, chalcopyrite and pyrrhotite are also present , but generally to a lesser

degree. Based on visual observations, Sulfide content related to gold mineralization can range

from 1% -15%, with most zones hosting 3 -5% total sulfide. Coarse visible gold is relatively

7

uncommon on the property and is presently identified at the Raine -Walker, TCA and Black

Diamond targets to-date.

Sampling and Analytical Procedures

All drill and surface samples from the Amisk Property were analyzed at TSL Laboratories Inc.

(“TSL”) in Saskatoon, Saskatchewan. Duplicate check assays were conducted at TSL and the

Saskatchewan Research Council, which are independent from SSR Mining. Mean results of the

spot checks were consistent with those reported. Sampling interval was established by minimum

or maximum sampling lengths and geological or structural criteria.

TSL prepares a minus-150 mesh pulp (95% passing) weighing 250 grams from a minus 10 mesh

coarse crush reject. Fire assay with Atomic Absorption finish was completed on a 30-gram aliquot

to produce gold analytical results with a 0.005 g/t gold detection limit. Fire assay with gravimetric

finish was prepared on those samples with greater than 3 g/t gold.

External review of data and processes relating to Amisk exploration data has been completed by

independent consultant Mr. Ron Konst. There were no adverse material results detected and the

Quality Assurance/Quality Control indicates the information collected is acceptable and can be

used for further studies.
