The following information herein supplements (the “Supplement”) the definitive proxy statement on Schedule 14A filed by SSR Mining Inc. (the “Company”) with the Securities and Exchange Commission (the “SEC”) on April 12, 2024, as amended on May 15, 2024 (the “Proxy Statement”) and made available to the Company’s shareholders in connection with the solicitation of proxies on behalf of the board of directors of the Company (the “Board”) relating to the Company’s 2024 Annual and Special Meeting (the “Annual Meeting”) of holders of common shares (“Shareholders”) scheduled to be held virtually on May 23, 2024 at 10:00 a.m. MDT (Denver), and any adjournment or postponement thereof.

This Supplement is being filed with the SEC and made available to shareholders on or about May 17, 2024. Capitalized terms used in this Supplement that are not otherwise defined in this Supplement have the meanings given to them in the Proxy Statement. The information disclosed in the Proxy Statement remains in full force.

The Proxy Statement includes a proposal (Proposal No. 3) to approve the Company’s 2024 Share Compensation Plan (the “Plan”). The Company seeks to clarify the following with respect to the Plan:

•The maximum number of Common Shares (as defined in the Plan) issued to Insiders (as defined in the Plan) within any one (1) year period and issuable to Insiders in the aggregate under all of the Company's security based compensation arrangements (referred to as the “Aggregate Plans” in the Plan), will not exceed 3.75% of the total number of Outstanding Common Shares (as defined in the Plan).

•The maximum number of shares issuable under the Plan will not exceed 5,000,000 Common Shares.

•The Company shall have the authority to continue granting share units under the Plan until May 23, 2027, which is the date that is three (3) years from the date of the Annual Meeting.

If information in this Supplement differs from or updates information contained in the Proxy Statement, then the information in this Supplement supersedes the different information contained in the Proxy Statement.

This Supplement should be read with the Proxy Statement and the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, as each contains information that is important to your decisions in voting at the Annual Meeting. From and after the date of this Supplement, any references to the Proxy Statement will be
