ARIS MINING REPORTS Q1 2026 PRODUCTION AND STRONG REVENUE GROWTH

Aris Mining Corp. had gold production of 74,300 ounces (oz) for the first three months of 2026 (Q1 (first quarter) 2026). All dollar amounts are in U.S. dollars unless otherwise indicated.

Q1 2026 highlights (1):

• Q1 consolidated gold production of 74,300 oz, a 6-per-cent increase over Q4 (fourth quarter) 2025;
• Q1 gold sales of 74,800 oz at an average realized price of more than $4,860 per oz, resulting in gold revenue of more than $360-million, up 20 per cnet from Q4 2025;
• Cash balance of over $470-million at March 31, 2026, an increase of approximately $80-million compared with Dec. 31, 2025.

Neil Woodyer, chair and chief executive officer, 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 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 Q4 2026.

Aris Mining's portfolio supports a longer-term objective of approximately one million ounces of annual gold production (2). Key projects include the high-grade Soto Norte gold project in Colombia, where environmental studies are being finalized for submission in Q2 (second quarter) 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.

(1) The Q1 2026 results contained in this news release are preliminary and may differ from the final results to be included in the company's interim financial statements and MD&A (management's discussion and analysis) for the period ended March 31, 2026, which the company expects to release in May, 2026. In addition, due to rounding, certain numbers presented in this news release may not sum precisely.

(2) Includes potential production estimates from Toroparu, which is based on a preliminary economic assessment and is preliminary in nature. It 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 for both Soto Norte and Toroparu.
