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.

____________________

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. There can be no assurance that

the projected production will be achieved. Such production also remains subject to obtaining all necessary permits

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