SSR MINING ANNOUNCES THE ACQUISITION OF AN UP TO 40% OWNERSHIP

INTEREST AND OPERATORSHIP IN THE HOD MADEN GOLD-COPPER

PROJECT THROUGH AN EARN-IN STRUCTURED TRANSACTION

Acquisition Of A World-Class Deposit That Fits SSR Mining’s Strategy, Geographic Focus,

And Leverages SSR Mining’s Core Strengths To Create Shareholder Value

Highlights

• SSR Mining to acquire an up to 40% interest and immediate operational control in the Hod Maden gold-copper development project

(“Hod Maden” or the “Project”) in northeastern Türkiye from Lidya Mines

• Aggregate acquisition consideration totals $ 270 million, which includes $120 million in upfront cash payment to acquire a 10%

interest in Hod Maden, followed by $150 million in earn-in structured milestone payments to acquire an additional 30% interest ,

payable between the start of construction and the first anniversary of commercial production 4

• The acquisition of Hod Maden will add one of the highest margin and lowest capital intensity development projects globally to SSR

Mining’s robust portfolio of high-return growth projects and is expected to deliver an estimated all-in after-tax internal rate of return

(“IRR”) in excess of 15% after acquisition costs

• Transaction is accretive to SSR Mining across all meaningful per share valuation metrics, including Net Asset Value, Mineral

Reserves, Mineral Resources, production, operating cash flow, and free cash flow 1

• Based on the Feasibility Study – Technical Report NI 43-101 effective February 28, 2021 (“the 2021 Feasibility Study”) published by

Horizon Copper Corp. 2, Hod Maden features a 13-year mine life averaging (on a 100% basis) approximately 195,000 ounces of gold

equivalent production annually at first quartile co-product AISC of $588/oz, generating $164 million of annual free cash flow and a

36% after-tax internal rate of return (“IRR”) at base case commodity prices of $1,599/oz gold and $3.19/lb copper 3

• Transaction projected to provide SSR Mining with approximately an expected attributable 80,000 gold equivalent ounces and $ 66

million in free cash flow annually (at $1,599/oz gold and $3.19/lb copper) once in production, expected in 2027 3

• Hod Maden is a world-class, high grade and high-margin asset which will further enhance SSR Mining’s free cash flow generation,

which has been a key pillar of the Company’s strategy and sector-leading capital returns program

• The Transaction leverages SSR Mining’s significant experience in Türkiye and its proven project development team that successfully

delivered the Çöpler Sulfide Expansion Project on time and under budget , provides in-country synergies, and builds on a long-

standing and strong joint venture partnership with Lidya Mines in Türkiye

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

announce that it has reached an agreement to acquire from Lidya Mines an up to 40% interest in, and operational

control of , the Hod Maden gold -copper development project, located in northeastern Türkiye (the “Transaction”).

Currently, Lidya Mines and Horizon Copper Corp. (“Horizon”) hold a 70% and 30% ownership interest, respectively,

in Hod Maden.

As consideration for the 40% ownership interest in Hod Maden, SSR Mining’s payments include:

• $120 million upfront cash payment to acquire a 10% interest in the Project paid on closing of the Transaction

on May 8, 2023; and

SSR Mining Inc. PAGE 2

• $150 million in earn-in structured cash milestone payments to acquire an additional 30% interest in the

Project, payable in accordance with an agreed upon sch edule beginning at the start of construction and

ending on the first anniversary of commercial production. 4

With the upfront cash payment made on closing , SSR Mining now serves as sole project operator responsible for

project development, construction and operations. Upon completion of the milestone payments, SSR Mining will own

40% of the Project. 4

Rod Antal, President and CEO of SSR Mining, said, “We have been closely monitoring Hod Maden for well over seven

years as it has progressed through critical development and permitting milestones, largely de-risking the Project as it

approaches a construction decision in 2024. Our due diligence team was complimentary as to the detail and quality

of work completed so far on the Project. Following our review and after discussions with our joint venture partners,

we believe there are several positive operational value levers as well as exploration potential beyond the existing life

of mine plan that was presented in the 2021 Feasibility Study. We will now spend the next twelve months updating

the existing technical report for these value enhancing opportunities, as well as to account for changes in market

conditions.

We would like to thank our joint venture partners in the Project for their support and cooperation during this process.

We are excited for the outcome , which delivers our stakeholders exposure to what we believe is one of the most

compelling undeveloped gold-copper projects in the world. It is clear that Hod Maden is one of the highest margin,

lowest capital intensity projects in the sector, and once operational should be a meaningful free cash flow contributor

to the SSR Mining business as our fifth producing asset. This is supported by the projected >15% IRR the Project will

generate after acquisition costs.

Our proven project development team will work to advance Hod Maden to a full construction decision in 2024 with a

goal of delivering first production in 2027. The same principles and discipline that enabled our team to deliver the

Çöpler Sulfide Plant project in Türkiye on time and under budget will be applied to Hod Maden to help us maximize

the value of the Project. The Project’s robust economics have the ability to support a project-level finance facility, and

we will build upon the project finance work completed by the joint venture to date as a potential funding opportunity

while limiting SSR Mining’s cash outlay . Overall, this prudently structured transaction presents an opportunity to

further our commitment to low capital intensity growth, strong free cash flow generation and continued robust capital

returns.”

Following completion of the earn-in structured cash milestone payments, SSR Mining will own 40% of the Project,

Lidya Mines will retain a 30% ownership interest and Horizon will own the remaining 30%. Horizon acquired its 30%

ownership in the Project from Sandstorm Gold Ltd. on August 31, 2022 in exchange for a gold stream on production

from a portion of Horizon’s 30% interest and certain other non -cash consideration . SSR Mining’s attributable

production and free cash flow are not encumbered by the gold streaming agreement between Horizon and Sandstorm.

As an upside sharing mechanism with Lidya Mines , if an additional 500,000 ounces of gold equivalent Mineral

Reserves, beyond those currently identified as Mineral Reserves and Mineral Resources (“MRMR”) in the 2021

Feasibility Study, are delineated, SSR Mining will make an $84 million payment to Lidya Mines.

Key regulatory approvals for the Transaction have been obtained and the transaction closed on May 8 th, 2023.
