Ssr Mining Announces Positive Exploration Results At Marigold Creating Pathways For Mine Plan Enhancement And Extension

Oxide Intercepts Include 4.2 g/t Au Over 26 Meters and 2.7 g/t Au Over 17 Meters at New Millennium; Updated Technical Report on Track for 2023

DENVER, Nov. 28, 2022 - SSR Mining Inc. (NASDAQ: SSRM) (TSX: SSRM) (ASX: SSR) ("SSR Mining" or the "Company") is pleased to announce results from 316 drillholes completed at the Marigold mine in Nevada, USA, for the period from October, 2021 to August, 2022 (Figure 1) at the New Millennium, Trenton Canyon and Buffalo Valley oxide targets. These results build upon, and are subsequent to, the Marigold 2021 Technical Report Summary. With an existing Mineral Reserve life of 11 years, exploration at Marigold is focused on adding higher-grade oxide ounces to the mine plan to both enhance and extend the current production profile and life of mine free cash flow generation. The continued exploration success at these key exploration targets has the potential to drive Mineral Reserve and Mineral Resource growth that can be incorporated into an updated Technical Report Summary for Marigold, which is expected in 2023 (the "2023 Marigold TRS"). The 2023 Marigold TRS will evaluate the potential to add New Millennium to the life of mine plan. Future studies will evaluate mining and processing opportunities at the Trenton Canyon and Buffalo Valley satellite targets located four and ten kilometers south of New Millennium, respectively.

The potential development of New Millennium was unlocked by recent brownfield strategic land acquisitions and presents an opportunity to add higher-grade oxide Mineral Reserves and Mineral Resources proximal to existing Marigold infrastructure. The New Millennium target area is comprised of six distinct zones which include East Basalt, Battle Cry, Antler, Section 6, Lil' Gun and North Antler. These targets are on the periphery of the Antler-Basalt pits that previously produced approximately one million ounces at a grade of 0.75 g/t. Nearly 45,000 meters of drilling was completed at New Millennium across 146 holes, with numerous intercepts significantly above Marigold's existing Mineral Reserve grade and new mineralization encountered more than five hundred meters south of previously defined Mineral Resources.

New Millennium oxide drilling highlights include (see Figures 2 and 3) (see Table 1):

• MRA7621: 25.9 meters at 4.2 g/t Au from 117.3 meters
• MRA7623: 16.8 meters at 2.7 g/t Au from 120.4 meters
• MRA7629: 22.9 meters at 1.7 g/t Au from 231.6 meters
• MRA7520: 21.3 meters at 1.7 g/t Au from 195.1 meters, and 19.8 meters at 1.9 g/t Au from 225.6 meters

Rod Antal, President and CEO of SSR Mining, said, "These results showcase exceptional oxide grades that have potential to drive Mineral Reserve and Mineral Resource growth and complement the existing Marigold production profile. We expect to include some of this higher-grade oxide material in the 2023 Marigold TRS, which we anticipate will demonstrate an optimized and expanded production profile through the incorporation of New Millennium. In addition, with the recent results from both Trenton Canyon and Buffalo Valley, we believe the future is very bright for Marigold with opportunities to extend the existing 11 year mine life while adding higher grade, lower cost oxide ounces to the near and longer-term mine plan."

In addition to drilling at New Millennium, SSR Mining continues to explore for supplemental oxide ore sources across the broader Marigold land package. At Trenton Canyon and Buffalo Valley, located approximately four kilometers south and ten kilometers southwest of New Millennium, respectively, drilling has delivered exciting high-grade intercepts of predominantly oxide mineralization. Exploration at these targets aims to define oxide material that leverages existing infrastructure at Marigold to provide an avenue for production growth in the future. Work also continues to delineate and define initial sulfide resources at each target that could represent potential longer-term development opportunities for Marigold.

Trenton Canyon oxide drilling highlights include (see Figures 4 and 5) (see Table 2):

• MRA7795: 15.2 meters at 11.1 g/t Au from 213.4 meters
• MRA7587: 19.8 meters at 5.5 g/t Au from 181.4 meters
• MRA7518: 6.1 meters at 2.0 g/t Au from 41.1 meters and 25.9 meters at 1.2 g/t Au from 50.3 meters

Buffalo Valley oxide drilling highlights include (see Figures 6, 7 and 8) (see Table 2):

• DDH7705: 18.3 meters at 6.2 g/t Au from 126.5 meters
• MRA7730: 42.7 meters at 1.4 g/t Au from 382.5 meters
• MRA7598: 6.1 meters at 2.5 g/t Au from 324.6 meters

Additionally, an infill drill hole from the Valmy pit located to the northeast of New Millennium included the following oxide intercepts:

• DDH7452: 14.3 meters at 4.7 g/t Au from 209.4 meters and 12.5 meters at 0.8 g/t Au from 246.3 meters

While the exploration focus is to define and expand oxide inventory across the greater Marigold property, SSR Mining is simultaneously exploring for structurally controlled sulfide mineralization potentially amenable to alternative mining & processing methods than those currently utilized at Marigold. Building on results previously announced in December 2021, exploration efforts at Trenton Canyon have focused on the Tempest zone, a series of high-grade structures proximal to the past-producing South and West pits.

Trenton Canyon sulfide drilling highlights include (see Figures 4 and 5) (see Table 3):

• DDH7525: 6.1 meters at 25.6 g/t Au from 185.8 meters
• Including 3.7m at 41.4 g/t Au from 185.8 meters
• MRA7561: 16.8 meters at 2.6 g/t Au from 144.8 meters
• MRA7708: 12.2 meters at 3.9 g/t Au from 172.2 meters

As the exploration team furthers its understanding of sulfide mineralization at Marigold, it is applying this knowledge to a robust collection of high-quality and underexplored targets throughout the extensive Trenton Canyon and Buffalo Valley properties. One example is the Spitfire target, located approximately two kilometers northwest of the Buffalo Valley pit.

Highlight intercepts from the Spitfire target include (see Figure 6) (see Table 3):

• MRA7609: 6.1 meters at 20.1 g/t Au from 111.3 meters
• DDH7600: 6.9 meters at 2.0 g/t Au from 292.8 meters, including coarse visible gold

Marigold Exploration Figures

Marigold Exploration Overview

SSR Mining's mineral holdings include a 100% owned approximately 20,000-hectare parcel containing the currently producing Marigold mine as well as the past producing Valmy, Trenton Canyon, North Peak, and Buffalo Valley mines. Activity during the Exploration Period (October 2021 to August, 2022) included 316 drillholes (308 reverse circulation and 8 core drillholes) focused on Mineral Reserve and Mineral Resource additions at New Millennium, Trenton Canyon, and Buffalo Valley, as well as infill drilling at the Mackay pit that improved confidence in existing Mineral Reserves and Mineral Resources.

New Millennium represents a low cost, high probability development opportunity in the Nevada portfolio and drilling at the target will continue with the ultimate goal to enhance and extend operations at Marigold beyond its current 11 year mine life. The New Millennium target area is comprised of six distinct zones which include East Basalt, Battle Cry, Antler, Section 6, Lil' Gun and North Antler, and was enabled by land acquisitions completed in 2016, 2018 and 2019.

Currently, the Company has four drill rigs on-site at Marigold and is undertaking geotechnical, metallurgical and geophysical studies to better understand the multitude of prospective opportunities across the Marigold property. This includes the recent launch of a UAV magnetics survey across the Trenton Canyon, Buffalo Valley and North Peak targets. North Peak is another past producing oxide pit that is located between Trenton Canyon and Buffalo Valley.

As exploration continues to define opportunities for Mineral Reserve and Mineral Resource growth at these targets, the Company is applying a "District Master Plan" approach to future development, permitting and production of these opportunities. This approach, used successfully at Çöpler in the past, ensures Marigold has a well-defined longer-term pipeline of growth projects.

The Company is also continuing a re-assay program of historical drill samples in the New Millennium area with the potential to build on the success of the re-assay program across the greater Marigold property, including re-assaying in 2015-2016 which yielded a 23% increase in estimated tonnage and a 13% increase in gold ounces within the Mackay pits. The goal of this program is to capture low-grade gold assay values not recorded in the historical dataset and integrate the results with the updated resource model. The first phase of this program, which included the re-analysis of drill samples from two drill sections at New Millennium, yielded positive results and was expanded to encompass the entire project area. The second phase of this program, which included approximately 650 samples, is also yielding positive results. The focus of this phase is to add value to ongoing drilling program.

Technical Procedural Information Sampling and Analytical Procedures

Drill samples from the Marigold mine drilling program were sent for processing and analysis to the offices of American Assay Laboratories, Inc. ("AAL") in Sparks, Nevada which is an ISO 17025 accredited laboratory independent from SSR Mining. Fire assay was completed on a 30-gram sample (AAL method code FA-PB30-ICP) with an Inductively Coupled Plasma finish after a two acid digestion. Samples with assay results greater than 10 g/t gold were fire assayed on a 30-gram sample (AAL method code Grav Au30) with a gravimetric finish. Buffalo Valley samples greater than one gram are subjected to Screen Fire assays. We employ a rigorous Quality Assurance/Quality Control ("QA/QC") program, which includes real-time assay quality monitoring through the regular insertion of blanks, duplicates, and certified reference material, as well as reviewing laboratory-provided QA/QC data and confirming results at umpire labs.

External review of data and processes relating to Marigold exploration data have been completed by an independent consultant F. C. Edmunds, P. Geo., in November 2022. 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.
