Aris Mining Announces Revisions to Equity Compensation Plan Ahead of Annual General Meeting

Aris Mining Corp. (Aris Mining or the Company) (TSX: ARIS; NYSE: ARIS) announced today that, based on further review of its proposed equity compensation plans, it has decided to revise those plans ahead of the Company's upcoming annual general meeting of shareholders to be held on May 7, 2026 (the AGM). The Company determined that the initially proposed share reserves were greater than required and has reduced the proposed share reserve caps for each of the security-based equity compensation plans. For context, the Company's 2026 long-term incentive awards granted in January 2026, including stock options, restricted share units and performance share units, represented approximately 0.35% of the Company's issued shares, underscoring that the initially proposed reserves were higher than necessary.

Under the revised approach, the Board of Aris Mining has approved the following changes:

• the amended and restated stock option plan (Stock Option Plan) has been updated to reduce its rolling reserve for stock options from 10% (as previously described in the Management Information Circular dated March 24, 2026 (the Circular) to 3% and to clarify the amendment provisions of the plan; and
• the amended and restated performance share unit plan (PSU Plan) and the amended and restated restricted share unit plan (RSU Plan) have been updated to reduce their combined rolling reserve from 5% to 3%.

As a result of these amendments, the total number of common shares that may be issued under the Company's equity compensation plans, when aggregated, has been reduced from 10% to 6% of the outstanding shares from time to time.

The updated versions of the Stock Option Plan, PSU Plan and RSU Plan are available on SEDAR+ and in the Company's filings with the U.S. Securities and Exchange Commission. These versions replace the corresponding plans included in the Circular (Schedules E, D, and C, respectively). Shareholders will be asked to approve the updated plans at the AGM (or any adjournment or postponement thereof). All references in the Stock Option Plan Resolution, PSU Plan Resolution and RSU Resolution to the Stock Option Plan, PSU Plan and RSU Plan in the Circular (as each of those terms are defined in the Circular), respectively, will be to the amended and restated versions of those plans filed on SEDAR+ and with the U.S. Securities and Exchange Commission on April 16, 2026.

The Company's Board of Directors recommends Shareholders vote FOR each of the Stock Option Plan Resolution, PSU Plan Resolution and RSU Plan Resolution. Unless you give other instructions, the management proxyholders intend to vote FOR the Stock Option Plan Resolution, PSU Plan Resolution and RSU Plan Resolution.

The Toronto Stock Exchange has conditionally approved each of the updated Stock Option Plan, PSU Plan and RSU Plan.

About Aris Mining

Aris Mining is a Canadian gold mining company focused on South America. The Company operates the Segovia and Marmato underground gold mines in Colombia, which together produced approximately 257,000 ounces of gold in 2025. Aris Mining is listed on the Toronto Stock Exchange and the New York Stock Exchange under the symbol ARIS.

The Company is advancing expansion projects at Segovia and Marmato that are expected to increase annual gold production to approximately 500,000 ounces, driven by the ramp-up at Segovia following the installation of the second mill, which was completed in June 2025, and construction of the new Marmato bulk mine and CIP plant, with first gold expected in Q4 2026.

Aris Mining's portfolio supports a longer-term objective of approximately 1 million ounces of annual gold production¹. Key projects include the high-grade Soto Norte gold project in Colombia, where environmental studies are being finalized for submission in Q2 2026 to initiate the licensing process, and the Toroparu gold project in Guyana, where a Prefeasibility Study is in progress and a construction decision is expected in early 2027.

¹ Includes potential production estimates from Toroparu, which is based on a preliminary economic assessment and is preliminary in nature. It includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the preliminary economic assessment will be realized. Mineral resources that are not mineral reserves do not have demonstrated economic viability. There can be no assurance that the projected production will be achieved. Such production also remains subject to obtaining all necessary permits for both Soto Norte and Toroparu.
