Aris Mining Reports Q1 2026 Production and Strong Revenue Growth

Gold revenue expected to exceed $360 million

Aris Mining Corporation (Aris Mining or the Company) (TSX:ARIS, NYSE:ARIS) reports gold production of 74.3 thousand ounces (koz) for the first three months of 2026 (Q1 2026). All amounts are in U.S. dollars unless otherwise indicated.

Q1 2026 Highlights¹:

• Q1 consolidated gold production of 74.3 koz, a 6% increase over Q4 2025.
• Q1 gold sales of 74.8 koz at an average realized price of more than $4,860 per oz, resulting in gold revenue of more than $360 million, up 20% from Q4 2025.
• Cash balance of over $470 million at March 31, 2026, an increase of approximately $80 million compared to December 31, 2025.

Neil Woodyer, Chair and CEO, commented "Our strong start to 2026 reflects both solid operating performance and a supportive gold price environment. We expect Q1 2026 gold revenue to exceed $360 million, a significant increase from $154 million in Q1 2025 and $301 million in Q4 2025, driven by higher gold prices and increased ounces sold. Looking ahead, we expect production growth in 2026 to be weighted toward the second half of the year, with first gold from the Marmato CIP plant on track for Q4 and a continued steady ramp-up at Segovia."

The Company expects to report full Q1 2026 financial and operating results on or about May 6, 2026.

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 production². 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.
