About Aris Mining
Founded in September 2022, Aris Mining was established with a vision to build a leading South America-focused gold
mining company. Our strategy blends current production and cashflow generation with transformational growth
driven by expansions of our operating assets, exploration and development projects. Aris Mining intends to unlock
value through scale and diversification. The Company is listed on the TSX (ARIS) and the NYSE -A (ARMN) and is led
by an experienced team with a track 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 underway, Aris Mining is targeting an
annual production rate of more than 5 00,000 ounces of gold, following the commissioning of the second mill at
Segovia, 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%
owned Soto Norte joint venture, where a PFS 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 project, where the new PEA is complete
and a PFS is underway.
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, we enable safe, legal, and environmentally responsible
