</p><p xmlns="http://www.w3.org/1999/xhtml">
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.

</p><p xmlns="http://www.w3.org/1999/xhtml">
The Company is advancing expansion projects at Segovia and Marmato that are expected to increase annual gold production to approximately 500,000 ounces<sup xmlns="http://www.w3.org/1999/xhtml">1</sup>, 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.

</p><p xmlns="http://www.w3.org/1999/xhtml">
Aris Mining’s portfolio supports a longer-term objective of approximately 1 million ounces of annual gold production<sup xmlns="http://www.w3.org/1999/xhtml">2</sup>. 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.

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.
