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 (ARIS)

and 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 gold 1.

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.
