Çöpler Update

Our primary focus at Çöpler continues to be the return of our missing colleagues to their families. Following the recovery of four of our missing colleagues, recovery efforts for the five remaining individuals continue. To-date over 6.7 million tonnes of heap leach material has been relocated as part of the ongoing recovery, containment and remediation activity, including 4.2 million tonnes from the Sabırlı Valley.

SSR Mining currently expects the completion of the removal of all displaced heap leach material resulting from the Çöpler Incident out of the Sabırlı Valley and into temporary storage locations in the third quarter of 2024. Concurrently, containment efforts have been completed alongside the removal of the displaced material with the installation of a grout curtain, coffer dam and buttress as well as the ongoing installation of pumping systems and diversion channels in the Sabırlı Valley.

In parallel with the recovery and containment work, the Company is progressing a remediation plan following comprehensive consultation and evaluations with various Turkish government agencies, ministries, independent experts and external consultants. The remediation plan will be submitted for government approval in the second quarter of 2024 and will include, among other things, the construction of a permanent storage facility for the displaced heap leach material. The design of the storage facility is capable of containing the approximately 18 to 20 million tonnes of displaced material in an area referred to as the East Storage Facility (see Figure 1).

The remediation work is expected to cost between $250 to $300 million on a 100% basis, in addition to the approximately $22.5 million incurred as of March 31, 2024. The remediation efforts are expected to be implemented over a period of 24 to 36 months. With a total cash position of $467 million at the end of the first quarter 2024, ongoing cash flow from three operations, and access to an additional $400 million revolving credit facility, the Company remains well positioned to fund these remediation commitments.

As part of the remediation plan, the heap leach pad will be permanently closed and no further heap leach processing will take place at Çöpler. In order to restart the operations, the Company will require the necessary operating permits and approvals. Once all necessary regulatory approvals, including the Environmental Impact Assessment (EIA) and operating permits, are reinstated, it is anticipated that initial ore processing at Çöpler will occur exclusively through the sulfide plant, which will process stockpiled material while Çöpler's mining team remains focused on completing the recovery and remediation work. As of the end of 2023, sulfide stockpiles totaled 10.8 million tonnes of ore at a grade of 2.0 grams per tonne gold, or approximately 706,000 contained ounces. At this time, the Company is not able to estimate when and under what conditions operations will resume at Çöpler.

In the first quarter of 2024, SSR Mining produced 101,873 gold equivalent ounces at cost of sales of $1,166 per payable ounce and AISC of $1,569 per payable ounce, which includes care and maintenance costs incurred at Çöpler. Excluding any production from Çöpler, and in line with existing guidance, SSR Mining expects Marigold, Seabee and Puna will produce a consolidated total of 340,000 to 380,000 gold equivalent ounces in 2024. ⁽¹⁾

More information related to the Çöpler Incident is included in the Company's Annual Report on Form 10-K filed on February 27, 2024 and in the Company's Quarterly Report on Form 10-Q filed on May 8, 2024. Further updates on the Çöpler Incident, as and when available, will continue to be provided through press releases and posts to the Company's website.

The Company reports non-GAAP financial measures including all-in sustaining costs ("AISC") per ounce sold (a common measure in the mining industry), 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 and a reconciliation to cost of sales, which is the most comparable GAAP financial measure.

First Quarter 2024 Summary: ⁽²⁾(All figures are in US dollars unless otherwise noted)

Çöpler Incident: On February 13, 2024, the Company suspended operations at Çöpler as a result of a significant slip on the heap leach pad.
Operating results: First quarter 2024 production was 101,873 gold equivalent ounces at cost of sales of $1,166 per payable ounce and AISC of $1,569 per payable ounce. Production from Marigold was 34,680 ounces of gold at cost of sales of $1,331 per payable ounce and AISC of $1,430 per payable ounce. At Seabee, production was 23,773 ounces of gold at cost of sales of $859 per payable ounce and AISC of $1,416 per payable ounce. Puna produced 1.9 million ounces of silver at cost of sales of $16.87 per payable ounce and AISC of $15.61 per payable ounce. Combined, these three assets produced 80,046 gold equivalent ounces in the first quarter of 2024, in line with expectations.
Financial results: Attributable net loss in the first quarter of 2024 was $287.1 million, or $1.42 per diluted share, reflecting approximately $272.9 million in incurred and anticipated reclamation and remediation costs, $114.2 million in non-cash impairment charges, and approximately $15.3 million in contingency and other costs related to the Çöpler Incident. Adjusted attributable net income in the first quarter of 2024 was $22.5 million, or $0.11 per diluted share. In the first quarter of 2024, operating cash flow was $24.6 million, or $32.3 million before working capital adjustments, and free cash flow was negative $9.4 million, or negative $1.8 million before working capital adjustments.
Cash and liquidity position: As of March 31, 2024, SSR Mining had a cash and cash equivalent balance of $467.0 million and a non-GAAP net cash position of $236.2 million. In addition, at the end of the first quarter 2024, the Company had no borrowings outstanding on its $400 million revolving credit facility.
Marigold operations: Gold production was 34,680 ounces in the first quarter of 2024 at cost of sales of $1,331 per payable ounce and AISC of $1,430 per payable ounce. As planned, first quarter 2024 results included increased waste stripping to support near-term development activities at Red Dot, which is a key focus for 2024 and 2025. Marigold's 2024 production remains approximately 70% weighted to the second half of 2024.
Seabee operations: Gold production was 23,773 ounces in the first quarter of 2024 at cost of sales of $859 per payable ounce and AISC of $1,416 per payable ounce. Milled grades of 6.5 g/t in the quarter included the processing of some material stockpiled from the fourth quarter of 2023, and grades are expected to average between 5.0 and 6.0 g/t for the remainder of the year.
Puna operations: Silver production was 1.9 million ounces in the first quarter of 2024 at cost of sales of $16.87 per payable ounce of silver and AISC of $15.61 per payable ounce of silver. Production in 2024 remains 55% weighted to the second half of the year, largely driven by grades that are expected to peak in the fourth quarter.
Hod Maden: During the first quarter of 2024, development activities at Hod Maden were temporarily reduced as the Company's staff in Türkiye focused on the Çöpler Incident. The Company has continued to advance engineering, execution planning activities and technical studies for the project. More details on the projected timelines for Hod Maden will be provided at a later date.

The non-GAAP financial measures are employed by us to measure our operating and economic performance and to assist in decision-making, as well as to provide key performance information to senior management. We believe that, in addition to conventional measures prepared in accordance with GAAP, certain investors and other stakeholders will find this information useful to evaluate our operating and financial performance; however, these non-GAAP performance measures – including total cash, total debt, net cash (debt), cash costs, all-in sustaining costs ("AISC") per ounce sold, adjusted net income (loss) attributable to shareholders, cash generated by (used in) operating activities before changes in working capital, free cash flow, and free cash flow before changes in working capital – do not have any standardized meaning. These performance measures are intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. Our definitions of our non-GAAP financial measures may not be comparable to similarly titled measures reported by other companies. These non-GAAP measures should be read in conjunction with our consolidated financial statements.

Non-GAAP Measure – Net Cash (Debt)

Net cash (debt) are used by management and investors to measure the Company's underlying operating performance. The Company believes that net cash (debt) is a useful measure for shareholders as it helps evaluate liquidity and available cash.

The following table provides a reconciliation of cash and cash equivalents to net cash:

Non-GAAP Measure - Cash Costs and AISC

Cash Costs and All-In Sustaining Costs ("AISC") per payable ounce of gold and respective unit cost measures are non-U.S. GAAP metrics developed by the World Gold Council to provide transparency into the costs associated with producing gold and provide a standard for comparison across the industry. The World Gold Council is a market development organization for the gold industry.

The Company uses cash costs per ounce of precious metals sold and AISC per ounce of precious metals to monitor its operating performance internally. The most directly comparable measure prepared in accordance with GAAP is cost of sales. The Company believes this measure provides investors and analysts with useful information about its underlying cash costs of operations and the impact of by-product credits on its cost structure. The Company also believes it is a relevant metric used to understand its operating profitability. When deriving the cost of sales associated with an ounce of precious metal, the Company includes by-product credits, which allows management and other stakeholders to assess the net costs of gold and silver production.

AISC includes total cost of sales incurred at the Company's mining operations, which forms the basis of cash costs. Additionally, the Company includes sustaining capital expenditures, sustaining mine-site exploration and evaluation costs, reclamation cost accretion and amortization, and general and administrative expenses. This measure seeks to reflect the ongoing cost of gold and silver production from current operations; therefore, growth capital is excluded. The Company determines sustaining capital to be capital expenditures that are necessary to maintain current production and execute the current mine plan. The Company determines growth capital to be those payments used to develop new operations or related to projects at existing operations where those projects will materially benefit the operation.

The Company believes that AISC provides additional information to management and stakeholders that provides visibility to better define the total costs associated with production and better understanding of the economics of the Company's operations and performance compared to other producers.

In deriving the number of ounces of precious metal sold, the Company considers the physical ounces available for sale after the treatment and refining process, commonly referred to as payable metal, as this is what is sold to third parties.

(13)	Care and maintenance expense only includes direct costs not associated with environmental reclamation and remediation costs, as depreciation is not included in the calculation of AISC.
(14)	Gold equivalent ounces are calculated by multiplying the silver ounces by the ratio of the silver price to the gold price, using the average LBMA prices for the period. The Company does not include by-products in the gold equivalent ounce calculations. Gold equivalent ounces sold may not add based on amounts presented in this table due to rounding.

Non-GAAP Measure - Adjusted Attributable Net Income (loss) and Adjusted Attributable Net Income (Loss) Per Share

Adjusted attributable net income (loss) and adjusted attributable net income (loss) per share are used by management to measure the Company's underlying operating performance. We believe this measure is also useful for shareholders to assess the Company's operating performance. The most directly comparable financial measures prepared in accordance with GAAP are net income (loss) attributable to SSR Mining shareholders and net income (loss) per share attributable to SSR Mining shareholders. Adjusted attributable net income (loss) is defined as net income (loss) adjusted to exclude the after-tax impact of specific items that are significant, but not reflective of the Company's underlying operations, including the expected impacts of Çöpler Incident; inflationary impacts on tax balances; transaction, integration; and other non-recurring items.

The following table provides a reconciliation of Net income (loss) attributable to SSR Mining shareholders to adjusted net income (loss) attributable to SSR Mining shareholders:

Non-GAAP Measure - Free Cash Flow, Cash Flow from Operating Activities before Changes in Working Capital, and Free Cash Flow before Changes in Working Capital

The Company uses free cash flow, cash flow from operating activities before changes in working capital, and free cash flow before changes in working capital to supplement information in its condensed consolidated financial statements. The most directly comparable financial measures prepared in accordance with GAAP is cash provided by operating activities. The Company believes that in addition to conventional measures prepared in accordance with US GAAP, certain investors and analysts use this information to evaluate the ability of the Company to generate cash flow after capital investments and build the Company's cash resources. The Company calculates free cash flow by deducting cash capital spending from cash generated by operating activities. The Company does not deduct payments made for business acquisitions.

The following table provides a reconciliation of cash provided by operating activities to free cash flow:

(in thousands of US dollars, except per share data)	Three Months Ended March 31,
	2024			2023
Cash provided by operating activities (GAAP)	$	24,631		$	2,967
Expenditures on mineral properties, plant, and equipment	$	(34,035	)	$	(59,242	)
Free cash flow (non-GAAP)	$	(9,404	)	$	(56,275	)

We also present operating cash flow before working capital adjustments and free cash flow before working capital adjustments as non-GAAP cash flow measures to supplement our operating cash flow and free cash flow (non-GAAP) measures. We believe presenting both operating cash flow and free cash flow before working capital adjustments, which reflects an exclusion of net changes in operating assets and liabilities, will be useful for investors because it presents cash flow that is actually generated from the continuing business. The Company calculates cash flow from operating activities before changes in working capital by adjusting cash provided by operating activities by the net change in operating assets and liabilities. The Company also calculates free cash flow before changes in working capital by deducting cash capital spending from cash flow from operating activities before changes in working capital.

The following table provides a reconciliation of cash provided by operating activities to cash generated by (used in) operating activities before changes in working capital, and free cash flow before changes in working capital:

(in thousands of US dollars, except per share data)	Three Months Ended March 31,
	2024			2023
Cash generated by (used in) operating activities (GAAP)	$	24,631		$	2,967
Net change in operating assets and liabilities	$	7,626		$	87,902
Cash generated by (used in) operating activities before changes in working capital (non-GAAP)	$	32,257		$	90,869
Expenditures on mineral properties, plant, and equipment	$	(34,035	)	$	(59,242	)
