ARIS MINING REPORTS STRONG GROWTH IN H1 2025 GOLD PRODUCTION

Aris Mining Corp. had gold production of 113,415 ounces (oz) for the first half (H1) of 2025, a 13-per-cent increase over H1 2024. With the successful commissioning of the expanded Segovia mill in June, 2025, and its ramp-up to 3,000 tonnes per day (tpd) now under way, the company remains on track to deliver its full-year production guidance of 230,000 to 275,000 oz. Gold production for 2025 is expected to be weighted to the second half of the year, reflecting increased milling capacity at Segovia.

Highlights:

• Second quarter (Q2) gold production of 58,652 oz, a 7-per-cent increase over the first quarter (Q1) of 2025;
• Q2 gold sales of 61,024 oz, a 12-per-cent increase over Q1 2025;
• Strong H1 2025 performance across both operations, with gold production up 12 per cent at Segovia and 26 per cent at Marmato compared with H1 2024.

Neil Woodyer, chief executive officer of Aris Mining, commented: "The commissioning of our second mill at Segovia marked a major milestone in our growth strategy. I'm particularly pleased that our team delivered the Segovia mill expansion on time and within budget while also maintaining strong operational performance. With increased production capacity, a strong gold price environment and operational momentum, we are well positioned to deliver a successful 2025."

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. The company's strategy blends current production and cash flow generation with transformational growth driven by expansions of its operating assets, exploration and development projects. Aris Mining is listed on the Toronto Stock Exchange (ARIS) and the New York Stock Exchange (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. Aris Mining is targeting an annual production rate of more than 500,000 ounces of gold, following the Segovia mill expansion, completed in June and ramping up during H2 2025, and the construction of the bulk mining zone at the Marmato complex, expected to start ramping up production in H2 2026. In addition, Aris Mining operates the 51-per-cent-owned Soto Norte joint venture, where studies are under way on a new, smaller-scale development plan, with results expected in the third quarter (Q3) of 2025. In Guyana, Aris Mining owns the Toroparu gold/copper project, where a new preliminary economic assessment (PEA) has been commissioned and its results are also expected in Q3 2025.

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, the company enables safe, legal and environmentally responsible operations that benefit both local communities and the industry.

Aris Mining intends to pursue acquisitions and other growth opportunities to unlock value through scale and diversification.
