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 ounces1, 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

production2. Key projects include the high-grade Soto Norte gold project in Colombia and the Toroparu gold project

in Guyana, where a Prefeasibility Study is in progress and a construction decision is expected in early 2027.

Additional information on Aris Mining can be found at www.aris-mining.com, www.sedarplus.ca, and on

www.sec.gov.

1 Reflects expected steady-state annual gold production of approximately 300 thousand ounces (koz) at Segovia and 200 koz at Marmato following completion

and ramp-up of the respective expansion projects . For more information, please refer to the Company’s news releases dated June 30, 2025 regarding the

Segovia expansion and March 12, 2025 regarding the Marmato expansion.

2 Includes potential production estimates from Toroparu, which is based on a preliminary economic assessment effective October 21, 2025 , which

contemplates a 7.0 Mtpa operation over a 21.3 -year mine life with average annual gold production of approximately 235 koz at a base case gold price of

US$3,000/oz. The preliminary economic assessment is preliminary in nature and 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. The re

can be no assurance that the projected production will be achieved. Such production also remains subject to obtaining all nec essary permits and to formal

construction decisions by the Company, in each case for both Soto Norte and Toroparu.
