SSR MINING ANNOUNCES POSITIVE EXPLORATION RESULTS AT COPPER HILL

Recent Drilling Includes 1.4% Cu Over 140 Meters and 2.2% Cu Over 32 Meters

Mineralization Defined From Surface and Approaching One Kilometer of Strike

DENVER - SSR Mining Inc. (NASDAQ/TSX: SSRM, ASX: SSR) ("SSR Mining" or the “Company") is pleased to

announce results from 42 diamond drill holes completed at the Copper Hill property (“Copper Hill” or “the Property”),

for the period from June, 2022 to October, 2022. Copper Hill is located approximately 30 kilometers southwest of

the town of Kürtün in the Black Sea region of northeast Türkiye, and is approximately 260 kilometers from SSR

Mining’s Hod Maden project (see Figure 1). Exploration at Copper Hill to date has focused on defining the initial

footprint of copper mineralization through diamond drilling. Reflecting the Property’s growth potential, SSR Mining

increased its ownership in the Copper Hill joint venture to 70% at the end of 2021.

At present, copper mineralization has been defined along nearly one kilometer of strike to a depth of approximately

250 meters below surface (see Figure 2). Currently, the mineralization exhibits low levels of other metals (less than

0.03% lead and zinc) and arsenic (averaging below 8ppm), suggesting potential for a clean copper concentrate

attractive to smelting companies. Results to date also showcase mineralization starting from surface over broad

intercepts that suggest potential for an open pit operation in the future. Exploration activity is planned to restart in

September, 2023, targeting potential extensions of the currently defined mineralization as well as identifying and

testing new targets on the property.

Copper Hill drilling highlights include (see Figures 2 through 5 and Table 1):

• CH002: 1.1% Cu over 37.0 meters from surface

• CH012: 1.4% Cu over 139.7 meters from 134.4 meters

o Including: 1.6% Cu over 33.9 meters from 204.2 meters and 3.5% Cu over 21.3 meters from 246.4

meters

• CH020: 2.2% Cu over 31.9 meters from 282.5 meters

• CH038: 1.4% Cu over 44.7 meters from 7.6 meters

o Including: 2.4% Cu over 18.6 meters from 22.0 meters

Significant intervals are reported at a nominal 0.2% copper cut-off and with a maximum 5 meters of contiguous dilution. All

thicknesses are down hole length, and true widths are not known at this stage.

Overview of the Copper Hill Property

Copper Hill is 70% owned and operated by SSR Mining and 30% owned by joint venture partner Lidya Mines (the

“Joint Venture”). Copper Hill sits within a package of exploration leases known as Kazıkbeli and all leases are

unencumbered by any existing royalties.

The Lidya Mines exploration team discovered Copper Hill and undertook the preliminary exploration activities on

behalf of the Joint Venture. Exploration activities were initiated in 2009, consisting of surface sampling (rock and soil

sampling) and ground magnetics. In April 2020, results were released for the initial eight diamond drill holes, totaling

3,181 meters, completed on the Property. To date, 77 diamond drill holes, totaling 24,600 meters, have been

completed. The northwest-southeast trending mineralized zone has been identified over a strike length of more than

900 meters with a minimum width of 300 meters and starting at surface to a currently defined depth extent of at

least 250 meters.

In addition to forthcoming drilling plans, the exploration team is planning geophysical surveys at Copper Hill for the

2023 field season, which aims to advance the continued definition of the potential overall extent of mineralization at

the Property. SSR Mining is also planning additional regional exploration activity to identify and test copper skarn

and porphyry targets across the greater Kazıkbeli land package.

Overview of Mineralization Style

Copper Hill is a skarn-type copper prospect associated with a late Cretaceous volcano-plutonic complex consisting

of a volcano-sedimentary sequence intruded by three intrusive phases. The intrusive phases include an east-west

trending elongate granite porphyry at the center of the current project area, along with a granodiorite to the south

and a feldspar porphyry to the southwest and northeast. Calcic exoskarn mineralization is west-northwest to east-

southeast trending and currently defined over a strike length of more than 900 meters, a width of 300 meters and to

a depth of at least 250 meters. The skarn mineralization resulted from the emplacement of a quartz feldspar

porphyry into the volcano-sedimentary sequence and decreases in thickness away from the intrusive contact.

Copper mineralization is almost entirely sulfide, with oxide zones typically very narrow and constrained close to

surface or immediately adjacent to significant faults. Four sets of high angle faults are found within the target area,

generated during a major compression post-dating the skarns and copper mineralization at Copper Hill.

Currently, the mineralization at Copper Hill is considered “clean” as it exhibits low levels of other metals (less than

0.03% lead and zinc) and arsenic (averaging below 8ppm), suggesting potential for a clean copper concentrate

attractive to smelting companies. This is atypical for skarn-type deposits and should bode well for future economic

studies on the Property.

Technical Procedural Information Sampling and Analytical Procedures

The diamond drill cores were sampled as half core at 1.0 meter intervals as an average or with variable core length

not smaller than 0.6 meters depending on the alterations and geological contacts. One half was sent to the assay

lab and the other half was retained as witness core. The samples were submitted to ALS Global laboratories in

Izmir, Türkiye for sample preparation and analysis which is an ISO/IEC 7025:2005 certified and accredited

laboratory. Bureau Veritas (Acme) laboratory, in Ankara, Türkiye was used for umpire check sample analysis. The

samples were analyzed for a full element suite Four Acid Digestion with ICP-AES Finish; ME-ICP61 (33 element

four acid-ICP-AES). For copper assays greater than or equal to 10%, aqua regia digestion with Four Acid Overlimit

Method was used; ME-OG62 (Ore Grade Elements - Four Acid- ICP-AES).

The total batch of 16,141 samples include 5.64% certified reference materials (“CRMs”), 5.12% blank and 9.66%

duplicates for a quality control insertion rate of not less than 20.43% of the total samples. SSR Mining conducts

routine QA/QC analysis on all assay results, including the systematic insertion of CRMs, blanks, field duplicates,

and umpire laboratory check assays. The certified reference materials were commercial standards from the Ore

Research Ltd. There were no adverse material results detected and the QA/QC indicates the information collected

is acceptable, and the database can be used for further studies.

SSR Mining's drill and geochemical samples were collected in accordance with accepted industry standards. SSR

Mining conducts routine QA/QC analysis on all assay results, including the systematic utilization of certified

External review of data and processes relating to the prospect was completed by independent Consultant Dr.

Erdem Yetkin, P.Geo. in December 2022.
