ARIS MINING DELIVERS 25% PRODUCTION GROWTH IN Q3 2025

Aris Mining Corp.'s gold production was 186,651 ounces for the first nine months of 2025. With the successful commissioning of the expanded Segovia mill in June, 2025, and its ramp-up advancing in line with expectations, the company remains on track to deliver its full-year production guidance of 230,000 to 275,000 oz.

Third quarter 2025 highlights:

• Q3 gold production of 73,236 oz, a 25-per-cent increase over second quarter 2025;
• Q3 gold sales of 73,001 oz, a 20-per-cent increase over Q2 2025;
• Strong performance at both operations with gold production up 27 per cent at Segovia and 8 per cent at Marmato, compared with Q2 2025;
• Cash balance of over $415-million (U.S.) at Sept. 30, 2025, including $13.2-million (U.S.) of proceeds from the sale of the Juby gold project.

Neil Woodyer, chief executive officer of Aris Mining, commented: "With increased production capacity at Segovia, solid operational momentum, a robust financial position and a favourable gold price environment, we are well positioned to deliver a strong finish to 2025 and build further momentum in 2026. Based on our performance to date, we are tracking above the midpoint of our 2025 production guidance."

About Aris Mining Corp.

Founded in September, 2022, Aris Mining was established with a vision to build a leading Latin America-focused gold mining company. Its strategy blends current production and cash flow generation with transformational growth driven by expansions of its operating assets, exploration and development projects. Aris Mining intends to unlock value through scale and diversification. The company is listed on the Toronto Stock Exchange (ARIS) and the NYSE American (ARMN), and is led by an experienced team with a record of value creation, operational excellence, financial discipline and good corporate governance in the gold mining industry.

Aris Mining operates two underground gold mines in Colombia: the Segovia operations and the Marmato complex, which together produced 210,955 ounces of gold in 2024. With expansions under way, Aris Mining is targeting an annual production rate of more than 500,000 ounces of gold, following the commissioning of the second mill at Segovia, completed in June and ramping up during second half 2025, and the construction of the Bulk mining zone at the Marmato complex, expected to start ramping up production in second half 2026. In addition, Aris Mining operates the 51-per-cent-owned Soto Norte joint venture, where a prefeasibility study is complete on a new, smaller-scale development plan, which confirms Soto Norte as a high-quality, long-life project with robust economics and industry-leading environmental and social design features. In Guyana, Aris Mining owns the Toroparu gold/copper project, where a new preliminary economic assessment is under way.

Colombia is rich in high-grade gold deposits, and Aris Mining is actively pursuing partnerships with the country's dynamic small-scale mining sector. With these partnerships, it enables safe, legal and environmentally responsible operations that benefit both local communities and the industry.

We seek Safe Harbor.
