**ARIS MINING EXPANDS HIGH-GRADE SEGOVIA RESERVE AND RESOURCE ESTIMATES** 

**Vancouver, Canada, January 8, 2026** – Aris Mining Corporation (Aris Mining or the Company) (TSX: ARIS; NYSE-A: ARMN) has updated the Segovia mineral reserve and resource estimates with an effective date of November 28, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;· Measured and indicated mineral resources increased by 7% to 3.6 million ounces of gold (Moz), up from
3.4 Moz in the 2024 estimate, while inferred resources increased by 12% to 2.9 Moz, reflecting continued exploration success and resource
growth at Segovia.

&nbsp;&nbsp;&nbsp;&nbsp;· Proven and probable mineral reserves increased by 12% to 1.5 Moz, up from 1.3 Moz in the 2024 estimate,
reflecting successful conversion of resources to reserves and ongoing mine development at Segovia.

&nbsp;&nbsp;&nbsp;&nbsp;· Segovia's mineral inventory remains exceptionally high grade, with measured and indicated resources
averaging 15.3 g/t Au and proven and probable reserves averaging 10.7 g/t Au.

Neil Woodyer, CEO of Aris Mining, commented "The updated Segovia reserve and resource estimates underscore the strength and durability of this exceptional high-grade asset. Compared to our prior estimates in 2024, measured and indicated resources increased by 7%, inferred resources grew by 12%, and proven and probable reserves increased by 12% or 160,000 ounces, net of mined depletion, reinforcing Segovia's long mine life and supporting higher production rates following the mill expansion. Segovia continues to provide a strong foundation of high-margin production and long-term value creation for Aris Mining."

Given the rapid and significant changes in the gold price over the past year, the selection of an appropriate gold price assumption for mineral resource reporting requires careful judgment. The Company selected a gold price of $3,200 per ounce for mineral resources and $2,800 per ounce for mineral reserves.

To provide transparency and context, the Company has included a mineral resource sensitivity analysis across a wide range of gold prices, from $2,100 per ounce, consistent with the gold price used in the 2024 estimate, to the $3,200 per ounce selected for the 2025 estimate. The sensitivity analysis demonstrates that the Segovia mineral resource is largely insensitive to gold price assumptions, with measured and indicated contained gold ranging from 3.4 Moz to 3.6 Moz, reflecting the high-grade nature and strong underlying economics of the deposit.

The table below summarizes the sensitivity of the 2025 mineral resource estimate to gold price.

**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 500,000 ounces of gold, driven by the commissioning of a second mill at Segovia, completed in June 2025 and ramping up since, and the construction of the Bulk Mining Zone at the Marmato Complex, with first gold expected in Q4 2026.

In Guyana, Aris Mining owns the Toroparu gold project, where a new Preliminary Economic Assessment has been completed and a Prefeasibility Study is in progress. Following completion of the PFS, Toroparu will be positioned to advance toward construction.

Aris Mining also owns the Soto Norte gold project, where a Prefeasibility Study has been completed on a smaller-scale development plan confirming Soto Norte as a high-grade, long-life project with strong economics and industry-leading environmental and social design features. Environmental studies are being finalized, which are scheduled to be submitted in the first half of 2026 to initiate the licensing process.
