DENVER - SSR Mining Inc. (NASDAQ/TSX: SSRM, ASX: SSR) ("SSR Mining" or the “Company") reports consolidated financial results for the fourth quarter and full year ended December 31, 2022. In addition, the Board of Directors declared a quarterly cash dividend of $0.07 per common share payable on March 30, 2023 to holders of record at the close of business on March 3, 2023. This dividend qualifies as an 'eligible dividend' for Canadian tax purposes.

Rod Antal, President and CEO of SSR Mining, said, “We closed 2022 with a strong balance sheet and met our revised guidance targets. We are now focused on delivering strong production and free cash flow in 2023. With the release of our 2023 and three-year guidance earlier this month, we presented our expectations for a significant year-over-year production improvement and a three-year production profile targeting 700,000 gold equivalent ounces.

Our 2023 cost guidance incorporates two significant growth initiatives for the business, the ramp-up at Çöpler’s Çakmaktepe Extension where first production is expected within the year, and waste stripping activities at Marigold’s Red Dot as we aim to optimize Marigold’s longer-term production profile. These initiatives, along with our continued advancement of the C2 expansion project at Çöpler and exploration and resource development activities across the portfolio, are key elements of our plan to sustain a longer-term production platform at or above 700,000 gold equivalent ounces annually.

Despite our continued and significant reinvestment in the business, we expect to deliver another strong year of free cash flow and capital returns to shareholders. The Company has a number of potential key catalysts targeted for 2023, including continued work on updated mine plans at Çöpler incorporating the C2 expansion project, and at Marigold highlighting the initial contribution of the New Millennium target. All considered, we see a strong and exciting year ahead for the business.”

Updated Mineral Reserves and Resources for Year End 2022

SSR Mining reported its updated MRMR as of December 31, 2022 in the Company’s Annual Report. For a detailed summary by asset, please refer to Item 2 Properties in the annual report, and for a reconciliation of year-over-year changes to the MRMR figures below, please see “Supplemental Mineral Reserve and Mineral Resource Information” at the end of this news release.

As per Subpart 1300 of Regulation S-K, MRMR are presented on an attributable basis.

The MRMR as of December 31, 2022 reflect depletion that occurred through mining activity, stockpile changes and changes resulting from asset acquisitions and divestments completed during 2022. SSR Mining continues to advance exploration and resource development activities at each of its assets, and this data will be incorporated into MRMR statements as the accompanying technical work so dictates. A summary of the Company’s year-end 2022 MRMR are presented below:

▪Commodity price assumptions unchanged from 2021: Commodity prices used in the calculation of Mineral Reserves for both 2022 and 2021 are $1,350/oz gold, $18.50/oz silver, $0.90/lb of lead, $1.05/lb of zinc, and $3.30/lb copper. Mineral Resource prices of $1,750/oz gold, $22.00/oz silver, $0.95/lb lead, $1.15/lb zinc and $3.95/lb copper were unchanged from 2021.

▪Acquisition of an additional 30% of Kartaltepe;Pitarrilla divested: In the fourth quarter of 2022, SSR Mining closed the Kartaltepe Transaction, consolidating SSR Mining’s 80% ownership of the entire Çöpler district. On an attributable basis, the transaction added 64,000 gold equivalent ounces in Mineral Reserves, 123,000 gold equivalent ounces in Measured and Indicated Mineral Resources, and 124,000 gold equivalent ounces in Inferred Mineral Resources to the Company’s MRMR. The accretive sale of the non-core Pitarrilla project in 2022 drove the reduction of silver and base metal Mineral Resources.

▪Mineral Reserves: Gold Mineral Reserves as of December 31, 2022 were 7.6 million, down 5% or 0.4 million ounces as compared to year-end 2021 Mineral Reserves reflecting mine depletion. Total gold equivalent Mineral Reserves as of December 31, 2022 were 8.3 million ounces, down 6% or 0.6 million ounces from 8.9 million ounces as compared to year-end 2021.

▪Measured and Indicated Mineral Resources: Gold Measured and Indicated Mineral Resources as of December 31, 2022 were 5.8 million ounces, effectively flat as compared to year-end 2021. Total gold equivalent Measured and Indicated Mineral Resources were 7.3 million ounces, a decrease of 9.5 million ounces from the prior year as a result of the divestment of the Pitarrilla project in 2022.

▪Inferred Mineral Resources: Gold Inferred Mineral Resources of 4.7 million ounces increased by 2% or 0.1 million ounces as compared to year-end 2021 Inferred Mineral Resources, a result of the acquisition of an additional 30% interest at the Kartaltepe licenses. Gold equivalent Inferred Mineral Resources of 5.8 million ounces decreased by 6% or 0.3 million ounces as compared to year-end 2021 Inferred Mineral Resources. This was largely driven by lower silver ounces as a result of the sale of Pitarrilla in 2022.

SSR Mining Mineral Reserves and Resources as of December 31, 2022 (8)

	Gold	y/y	Silver	y/y	Lead	Zinc	Copper	GEO (11)
	koz	%	koz	%	Mlb	Mlb	Mlb	Koz

(8)MRMR are shown as attributable to SSR Mining only. SSR owns 80% of the Çöpler district.

(9)At Seabee, a $1,600/oz gold price was used in the calculation of Mineral Reserves for 2021 and 2022 to better align with site-level mine plans.

(10)Measured and indicated Mineral Resources are shown exclusive of Mineral Reserves.

(11)All gold equivalent ounces (GEO) figures are based on the above-mentioned commodity prices. metal equivalence is calculated for the respective and applicable metals as follows: AuEq = Au koz + ((Ag koz * Ag price) + (Pb klb * Pb price per pound) + (Zn klb * Zn price per pound) + (Cu klb * Cu price per pound)) / (Au price per ounce).

(12)The Company reports the non-GAAP financial measures of cash costs and AISC per ounce of gold sold to manage and evaluate operating performance at Çöpler. See "Non-GAAP Financial Measures" for an explanation of these financial measures and a reconciliation to cost of sales, which are the comparable GAAP financial measure. For the three and twelve months ended December 31, 2022, cash costs and AISC per ounce of gold sold include the impact of any fair value adjustment on acquired inventories. For the three and twelve months ended December 31, 2021, cash costs and AISC per ounce of gold sold exclude the impact of any fair value adjustment on acquired inventories.

For the three months ended December 31, 2022 and 2021, Çöpler produced 65,603 and 92,069 ounces of gold, respectively. During the fourth quarter of 2022, cost of sales was $1,065 per ounce while AISC were $1,269 per ounce. The sulfide plant operated at an average throughput rate of more than 8,000 tonnes per day in the fourth quarter of 2022, a quarterly record and reflecting the successful restart of operations that began in the third quarter of 2022.

For the twelve months ended December 31, 2022 and 2021, Çöpler produced 191,366 and 329,276 ounces of gold, respectively. During the full year 2022, cost of sales was $985 per ounce while AISC were $1,328 per ounce. Operations at Çöpler were suspended in late June until late September in response to a leak of leach solution containing diluted cyanide at the Çöpler mine site on June 21, 2022. After completing the required improvement initiatives in early August, the Company received the required regulatory approvals on September 22, 2022 from Türkiye’s Government authorities and all operations were subsequently restarted.

In 2023, Çöpler is expected to produce 240,000 to 270,000 ounces of gold at mine site cost of sales of $1,070 to $1,100 per payable ounce and AISC of $1,245 to $1,295 per payable ounce, reflecting the costs associated with the ramp up of mining activity at the Çakmaktepe Extension starter pit, where first production is expected in 2023. Ҫӧpler’s production profile is approximately 55% weighted to the second half of 2023, reflecting a second half weighted grade profile and the planned maintenance shutdown in the second quarter of 2023. The C2 expansion project continues to progress towards a pre-feasibility study, including maiden Mineral Reserves and updated Mineral Resources, anticipated in the second half of 2023.

See "Non-GAAP Financial Measures" for an explanation of these financial measures and a reconciliation to cost of sales, which are the comparable GAAP financial measure.

For the three months ended December 31, 2022 and 2021, Marigold produced 62,875 and 57,405 ounces of gold, respectively. The fourth quarter of 2022 represented a strong finish to the year for Marigold and included the continued recovery of the higher grade ounces stacked earlier in 2022. During the fourth quarter of 2022, cost of sales was $1,004 per ounce while AISC were $1,160 per ounce.

For the twelve months ended December 31, 2022 and 2021, Marigold produced 194,668 and 235,282 ounces of gold, respectively. During the full year 2022, cost of sales was $1,053 per ounce while AISC were $1,378 per ounce.

In 2023, Marigold is expected to produce 260,000 to 290,000 ounces of gold at mine site cost of sales of $1,000 to $1,030 per payable ounce and AISC of $1,315 to $1,365 per ounce. For the full year, production is expected to be 60 to 70% weighted to the second half of 2023, reflecting a slower than expected leach cycle due to the increased proportion of finer ore stacked to the pads earlier in 2022. Marigold’s cost profile is expected to largely reflect the 2023 production profile, with first half costs above the full-year guidance range and the lowest cost periods in the third and fourth quarters.

Activities to enhance and extend the Marigold life of mine plan are continuing to advance. This includes accelerating spend associated with waste stripping activity at the Red Dot target in order to optimize the production profile for the remainder of the decade. In 2023, $28 million of Marigold’s $81 million sustaining capital budget is allocated to the purchase of new haul trucks. The stripping activity associated with Red Dot accounts for nearly $100 per ounce of SSR Mining’s corporate-level cost of sales. .

In 2023, Seabee is expected to produce 100,000 to 110,000 ounces of gold at mine site cost of sales of $810 to $840 per payable ounce and AISC of $1,160 to $1,210 per payable ounce. Seabee’s production is expected to be 55% weighted to the second half of the year, as processed grades are expected to be lowest in the first and second quarters of 2023 before improving in the second half. Mine and plant productivity are expected to average between 1,250 and 1,300 tonnes per day through 2023. Cost of sales and AISC are expected to be highest in the first half of the year, particularly in the first quarter, reflecting the concentration of capital spend associated with the Seabee ice road.

Dividend Declaration

On February 22, 2023 the Board of Directors declared a quarterly cash dividend of $0.07 per common share, payable on March 30, 2023 to holders of record at the close of business on March 3, 2023. This dividend qualifies as an eligible dividend for Canadian income tax purposes.

The dividend payment applies to holders of SSR Mining’s common shares, which trade on the Toronto Stock Exchange and the Nasdaq under the symbol SSRM, and to holders of its CHESS Depositary Interests (“CDIs”), which trade on the Australian Securities Exchange under the symbol SSR. Each CDI confers a beneficial interest in one common share. Therefore, CDI holders are entitled to a dividend calculated on the same basis as the holders of SSR Mining’s common shares.

SSR Mining has sought and been granted a temporary waiver of certain of the ASX Settlement Operating Rules. Under the authority of the waiver, the processing of conversions of common shares to CDIs, or CDIs to common shares, lodged on or after or after March 2, 2023, will be deferred until after the record date of March 3, 2023. The key dates with respect to the dividend are as follows:

Last date for processing requests to convert CDIs into common shares and to convert common shares into CDIs before the record date for the dividend	March 1, 2023
CDIs trade on the ASX on an ex‐dividend basis	March 2, 2023
Common shares trade on the TSX and Nasdaq on an ex‐dividend basis	March 2, 2023
Record date for the dividend	March 3, 2023
Processing recommences for requests to convert CDIs into common shares and to convert common shares into CDIs	March 6, 2023
Common share dividend payment date (in Canada and the United States)	March 30, 2023
Payment of dividend to CDI holders (in Australia)	March 31, 2023

Payments to Canadian shareholders will be made in Canadian dollars based on the exchange rate on the record date as reported by the Bank of Canada. Payments to other shareholders will be made in U.S. dollars. For CDI holders, payments will be made in Australian dollars, and it is expected to be based on the prevailing exchange rate sourced from the wholesale foreign exchange market on or around 5 business days after the record date.

Cautionary Note Regarding Non-GAAP Financial Measures

We have included certain non-GAAP financial measures to assist in understanding the Company’s financial results. 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 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.

Cash costs, AISC per ounce sold, adjusted attributable net income (loss), free cash flow, and net cash are Non-GAAP Measures with no standardized definition under U.S GAAP.

Non-GAAP Measure – Net Cash

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

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

	As of
(in thousands)		December 31, 2022		December 31, 2021
Cash and cash equivalents		$	655,453	$	1,017,562

Net Cash (Debt)		$	387,309	$	681,415

Non-GAAP Measure - Cash Costs and AISC

The Company uses cash costs per ounce of precious metals sold 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 and ability to generate cash flow. When deriving the cost of sales associated with an ounce of precious metal, the Company includes by-product credits. Thereby allowing management and other stakeholders to assess the net costs of gold and silver production. In calculating cash costs per ounce, the Company also excludes the impact of specific items that are significant, but not reflective of its underlying operations.

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, expansionary capital and non-sustaining expenditures are excluded. Certain other cash expenditures, including tax payments and financing costs are also excluded.

The Company believes that AISC represents the total costs of producing gold and silver from current operations and provides the Company and other stakeholders with additional information about its operating performance and ability to generate cash flows. It allows the Company to assess its ability to support capital expenditures and to sustain future production from the generation of operating cash flows.

When 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.

Non-GAAP Measure - Adjusted Attributable Net Income (loss)

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 equity holders of SSR Mining and net income (loss) per share attributable to equity holders of SSR Mining. 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 impairment charges; foreign exchange (gains) losses and inflationary impacts on tax balances; transaction, integration, and SEC conversion expenses; and other non-recurring items.

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

Non-GAAP Measure - Free Cash Flow

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

	Three Months Ended				Twelve Months Ended
(in thousands of US dollars, except per share data)	December 31,				December 31
	2022		2021		2022		2021
Net cash provided by operating activities (GAAP)	$	118,097	$	184,606	$	160,896	$	608,986
Expenditures on mineral properties, plant, and equipment (30)	$	(21,360)	$	(35,886)	$	(137,515)	$	(164,810)
Free cash flow (non-GAAP)	$	96,737	$	148,720	$	23,381	$	444,176

(30)Represents purchases of plant and equipment, excluding purchases of mineral properties.

Starting in this period, we are presenting 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 free cash flow before changes in working capital:

	Three Months Ended				Twelve Months Ended
