Neil Woodyer, Chair and CEO of Aris Mining, commented "We believe the move to the NYSE will enhance our visibility among U.S. and global institutional investors and better reflect the growing scale and quality of our portfolio. Aris Mining is building a leading gold mining company in South America with the potential to reach one million ounces of annual gold production from our 100% owned mines and development projects¹. Aligning our U.S. and Canadian trading symbols under 'ARIS' further strengthens our corporate identity across global capital markets."

About Aris Mining

Founded in September 2022, Aris Mining was established with a vision to build a South America-focused gold mining company. Our strategy combines current production and cashflow generation with transformational growth driven by expansions of its operating assets, exploration, and development projects. Aris Mining intends to unlock value through scale, diversification and execution. The Company is listed on the TSX (ARIS) and the NYSE American and has been approved to uplist to the New York Stock Exchange. Aris Mining is led by an experienced team with a strong 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: Segovia and Marmato, which together produced approximately 257,000 ounces of gold in 2025. With expansions underway, the Company is targeting an annual production rate of 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 CIP plant at Marmato, with first gold expected in Q4 2026.

Beyond its operating assets, Aris Mining has a development pipeline that supports its longer-term growth outlook to achieve annual production of approximately 1.0 million ounces of gold¹. Aris Mining owns the Toroparu gold project in Guyana, where a Preliminary Economic Assessment was completed in October 2025 and a Prefeasibility Study is in progress, positioning the project to advance toward construction. In Colombia, Aris Mining also owns the high-grade Soto Norte gold project, where a Prefeasibility Study was completed in September 2025 that balances scale and strong economics with industry leading environmental and social design features. Environmental studies are being finalized and on schedule for submission in Q2 2026 to initiate the Soto Norte licensing process.

__________________________________________

¹ Includes potential production estimates from Toroparu, which is based on a preliminary economic assessment and is preliminary in nature. It includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the preliminary economic assessment will be realized. Mineral resources that are not mineral reserves do not have demonstrated economic viability. There can be no assurance that the projected production will be achieved. Such production also remains subject to obtaining all necessary permits for both Soto Norte and Toroparu.
