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 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 upper mine, 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 ramp-up of the Segovia mill expansion, expected during the second half of 2025, and the new Marmato mine, which is expected to start ramping up in H2 (second half) 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 mid-2025. In Guyana, Aris Mining owns the Toroparu gold/copper project, further diversifying its asset portfolio.

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.
