Aris Mining Announces Revisions to Equity Compensation Plan Ahead of

Annual General Meeting

VANCOUVER, British Columbia--(BUSINESS WIRE)--April 16, 2026--Aris Mining

Corporation (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.
