About Aris Mining Corp.

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 fourth quarter 2026.

Aris Mining's portfolio supports a longer-term objective of approximately one million ounces of annual gold production. Key projects include the high-grade Soto Norte gold project in Colombia, where environmental studies are being finalized for submission in second quarter 2026 to initiate the licensing process, and the Toroparu gold project in Guyana, where a prefeasibility study is in progress, with a construction decision expected in early 2027 following the completion of the prefeasibility study.
