SSR MINING INC.

20. COMMITMENTS AND CONTINGENCIES

General

Estimated losses from loss contingencies are accrued by a charge to income when information is available prior to the issuance of the financial statements that indicates it is probable that a liability could be incurred, and the amount of the loss can be reasonably estimated. Legal expenses associated with the loss contingency are expensed as incurred. If a loss contingency is not probable or reasonably estimable, disclosure of the loss contingency is made in the financial statements when it is at least reasonably possible that a material loss has been incurred.

Environmental matters

CC&V - Carlton Tunnel

The Carlton Tunnel was completed in 1941 with the purpose of draining the southern portion of the mining district, subsequently consolidated by CC&V. CC&V has held discharge permits for the Carlton Tunnel since 1983, primarily to focus on monitoring. The monitoring data accumulated since the mid-1970s have indicated consistency in the water quality discharged from the Carlton Tunnel over time and work with the regulator has confirmed that the water flowing out of the Carlton Tunnel portal is akin to natural spring water and did not constitute mine drainage. However, in January 2021, the Water Quality Control Division of the Colorado Department of Public Health and Environment (the “Division”) issued new discharge permits imposing new water quality limits. On March 9, 2026, Newmont, the former indirect parent company of CC&V, and CC&V (as a Nominal Plaintiff in the Action), filed a lawsuit in federal court against the Colorado Water Quality Control Division seeking a declaratory judgment that federal and state law do not require the discharge permit for the Carlton Tunnel outflows. Depending on the outcome of the lawsuit and plans that may ultimately be agreed with regulators, a material adjustment to the remediation liability may be required. On June 26, 2026, defendants moved to dismiss the Action and the plaintiffs have responded to oppose the motion. As of August 21, 2026 all briefing on defendant’s motion to dismiss is complete, and the motion is pending review by the federal court.

Surety bonds

The Company uses surety bonds to support certain environmental bonding obligations. As of September 30, 2026, and December 31, 2025, the Company had surety bonds totaling $512.3 million and $500.1 million outstanding, respectively.

Other commitments and contingencies

Following the incident at the Company’s Çöpler mine in February 2024, as described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025, the Company has been named as a defendant in securities class actions in the United States and Canada and is subject to various risks and contingencies arising in the normal course of business. Based on the information currently available to the Company, no liability has been recorded for these lawsuits because the Company believes that any such liability is not probable and reasonably estimable at this time.
