H1 2026 gold production up 31% from H1 2025

Aris Mining Corporation (Aris Mining or the Company) reports gold production of 148.0 thousand ounces (koz) for the six months ended June 30, 2026 (H1 2026), a 31% increase over H1 2025. Gold sales of 147.0 koz in H1 2026 generated revenue of over $680 million. The Company remains on track to meet its 2026 production guidance, with key growth initiatives progressing on schedule, including first gold from the new Marmato CIP plant in Q4 2026. These results reinforce Aris Mining’s compelling growth profile. All amounts are in U.S. dollars unless otherwise indicated.

Q2 2026 Highlights:¹

• H1 2026 consolidated gold production of 148.0 koz, up 31% from H1 2025.
• Q2 2026 consolidated gold production of 73.7 koz, up 26% from Q2 2025.
• Q2 2026 gold sales of 72.1 koz at an average realized price of approximately $4,445 per ounce, resulting in Q2 2026 gold revenue of approximately $320 million and over $680 million for H1 2026.
• Cash balance of over $425 million at June 30, 2026.

Neil Woodyer, Chair and CEO, commented “We delivered a strong first half of 2026, with gold production up 31% from the same period in 2025, and we remain on track to deliver our 2026 production guidance of 300,000 to 350,000 ounces. We expect gold production to increase in the second half of the year, supported by the ongoing production ramp-up at Segovia and near-term completion of construction of the new Marmato CIP plant.

At Marmato, increased underground mining capacity contributed to production growth processed through the existing small-scale flotation plant. Construction of the CIP plant is progressing well, with mill components being assembled, and first gold remains on track for Q4 2026. Together, Segovia and Marmato are expected to produce approximately 500,000 ounces of gold per year once ramped up.”

The Company expects to report full Q2 2026 financial and operating results on or around July 29, 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 production.² 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.

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.
