SSR MINING ANNOUNCES INITIAL 12 YEAR LIFE OF MINE PLAN

FOR CC&V WITH AN NPV5% OF $824M AND POTENTIAL FOR FURTHER

MINERAL RESERVE CONVERSION

DENVER – SSR Mining Inc. (Nasdaq/TSX: SSRM) (“SSR Mining” or the “Company”) announces the results of a

Technical Report Summary (“TRS”) for the Cripple Creek & Victor Gold Mine (“CC&V”) in Colorado, USA (the “2025

CC&V TRS”).

Highlights of the 2025 CC&V TRS:

• After-tax NPV5% of $824 million at consensus gold prices averaging $3,240 per ounce over the life of mine

o After-tax NPV5% increases to approximately $1.5 billion at a gold price of $4,000 per ounce

• 12-year mine life, 26 years of total production based on 2.8 million ounces of gold Mineral Reserves

• Average annual production of 141,000 ounces of gold over the three-year period from 2026 to 2028

o Over the same three-year period, annual after-tax operating cash flow and free cash flow averages $196

million, and $128 million, respectively, based on consensus gold prices (1)

▪ At a gold price of $4,000 per ounce, annual after-tax operating cash flow and free cash flow from 2026

to 2028 averages $235 million and $168 million, respectively

• Measured & Indicated Mineral Resources, exclusive of Mineral Reserves, total 4.8 million ounces of gold with

an additional 2.0 million ounces of Inferred Mineral Resources, highlighting potential for future growth

o The gold prices used in the calculation of CC&V Mineral Reserves and Mineral Resources are $1,700/oz

and $2,000/oz, respectively. These gold price assumptions are unchanged from CC&V’s prior Mineral

Reserve and Mineral Resource statement as of December 31, 2024

• Based on the upfront $100 million cash payment in February 2025 , upcoming contingent payments , realized

mine site after-tax free cash flow and the TRS free cash flow projections, the acquisition of CC&V has an implied

after-tax transaction IRR in excess of 100%

Rod Antal, Executive Chairman of SSR Mining, said, “The transformational acquisition of CC&V established SSR

Mining as the third largest gold producer in the United States , with two core operations each with mine lives in

excess of 10 years. Following a very successful integration process , CC&V has already paid back the initial $100

million upfront acquisition price in mine-site after-tax free cash flow. Including the total potential transaction outlay

(1) The Company reports non-GAAP financial measures including after-tax free cash flow to manage and evaluate its operating performance at

its mines. See "Cautionary Note Regarding Non-GAAP Financial Measures" for an explanation of this financial measure to the most comparable

GAAP financial measures.

of $275 million, the results from this initial Technical Report Summary demonstrate a transaction IRR in exce ss of

100%, a truly exceptional outcome with meaningful growth potential for the operation still ahead.

Today’s initial life of mine plan already demonstrates a long-lived operation and with nearly five million ounces of

Measured & Indicated Mineral Resources and two million ounces of Inferred Mineral Resources, there is a clear

opportunity for future growth.”

The TRS, with an effective date of July 1, 2025 , has been prepared in accordance with S-K 1300 and will be

available by November 14, 2025 on the Company’s website and on a Current Report on Form 8-K to be filed with

the U.S. Securities and Exchange Commission (“SEC”).

Since closing of the CC&V acquisition during the first quarter of 2025, the mine has produced 85,165 ounces of

gold from February 28, 2025 to September 30, 2025 , and continues to track to the top -end of its attributable 2025

production guidance of 90,000 to 110,000 ounces. Over this same time period, CC&V has generated approximately

$115 million in mine site after-tax free cash flow to SSR Mining. Inclusive of the $100 million upfront cash payment

and $175 million in future contingent payments, realized free cash flow and the life of mine projections outlined in

the 2025 CC&V TRS, the acquisition is expected to provide SSR Mining with an IRR in excess of 100%.

Figure 3: SSR Mining’s Mineral Reserves & Mineral Resources by U.S. Asset

The majority of ore mined in the 2025 CC&V TRS is expected to be sourced from the currently active Globe Hill,

Schist Island and South Cresson pits. On average, the operating period from 2026 to 2036 includes average

stacking rates of 52,000 tonnes per day, and total material movement rates of 85,000 tonnes per day for a life of

mine strip ratio of 0.65:1. The average life of mine gold recovery is 51.6%, with an average stacked grade of 0.39

grams per tonne. Approximately 5% of all ore stacked over the life of mine is currently planned to be crushed, with

the remainder placed as Run of Mine (“ROM”) ore. Placement rates and crushed versus ROM considerations reflect

thorough technical analysis and ensure a minimum sufficient leach cycle time of 120 days. The TRS production

plan also includes approximately 334,000 ounces of recoverable gold currently in process inventory.

The CC&V mine is grid connected , with emergency power available via backup diesel generators for critical

systems. The current CC&V heavy equipment fleet includes 17 haul trucks, two front-end loaders and two hydraulic

shovels. NSR royalties across the CC&V property range from 0.5% to 10.0%, with an effective life of mine average

royalty rate of 5%.

Additional potential for upside at CC&V

The CC&V property covers over 15,000 acres within one of the most prolific gold mining districts in US history. More

than 2.8 million meters of drilling have been completed across more than 17,000 drill holes on the CC&V property.

While not all of this historical drilling has been factored into current Mineral Reserve and Mineral Resource

compilations, as of July 1, 2025, CC&V hosted more than 4.8 million ounces of Measured and Indicated Mineral

Resources and an additional 2.0 million ounces of Inferred Mineral Resources, both exclusive of Mineral Reserves.

These significant Mineral Resource s present considerable potential for growth in the future. A constraint in the

definition of Mineral Reserves as compared to Mineral Resources is the available Valley Leach Facility (“VLF”)

capacity for the placement of additional ore tonnes. The Mineral Reserves included in the 2025 CC&V TRS are

therefore constrained by the VLF capacity provided by the currently in -process Amendment 14 permit with the

Colorado Division of Reclamation, Mining, and Safety (“DRMS”) and Teller County. Amendment 14, once approved,

will provide incremental heap leach pad capacity to process 171 million tonnes (189 million short tons) and support

the CC&V Mineral Reserve life as outlined in the 2025 TRS.

SSR Mining is continuing to evaluate other opportunities for future growth at CC&V, including additional resource

development and exploration drilling across the property , as well as opportunities for fleet optimization and other

potential operating improvements.

2025 CC&V Transaction Overview (8)

1

As announced in December 2024, consideration for the acquisition of CC&V was comprised of a $100 million upfront

cash payment made on closing of the transaction on February 28, 2025 , as well as u p to $175 million in cash

milestone-based payments. These milestone payments were separated into two tranches:

• $87.5 million will be payable upon final approval of the application to amend the CC&V Cresson Permit

(“Amendment 14”). This permit amendment was filed by Newmont on April 25, 2024, with the scope to

extend the life of mine by adding 189 million short tons (171 million metric tonnes) of leach pad capacity

through construction of Phase 4 of the Valley Leach Facility 2 (“VLF2”) and Phase 6 of Valley Leach Facility

1 (“VLF1”), amongst other operational considerations including pit laybacks and road adjustments ; and

• Up to $87.5 million will be payable upon obtaining regulatory relief relating to flow -related permitting

requirements for the Carlton Tunnel, including steps taken to achieve the highest feasible alternative in

relation to Carlton Tunnel water flow.

Upon completion of an updated regulator-approved closure plan and in the event aggregate closure costs at CC&V

exceed $500 million, SSR Mining will be responsible for funding 10% of the incremental closure costs while

Newmont will be responsible for fundin g 90% of the incremental closure costs, either on an as -incurred basis or

pursuant to a lump sum payment option. Reclamation and closure costs in the 2025 CC&V TRS total $517 million.
