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

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
  • 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
  • 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.

See Table 2 for additional details on the intercepts listed in this table.

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 reference materials, blanks, field duplicates and umpire laboratory check assays.
