About Aris Mining

Aris Mining is a Canadian gold mining company focused on South America. The Company operates the Segovia and Marmato underground gold mines in Colombia, which together produced approximately 257,000 ounces of gold in 2025. Aris Mining is listed on the Toronto Stock Exchange and the New York Stock Exchange under the symbol ARIS.

The Company is advancing expansion projects at Segovia and Marmato that are expected to increase annual gold production to approximately 500,000 ounces¹, driven by the ramp-up at Segovia following the installation of the second mill which was completed in June 2025, and construction of the new Marmato bulk mine and CIP plant, with first gold expected in Q4 2026.

Aris Mining’s portfolio supports a longer-term objective of approximately 1 million ounces of annual gold production². Key projects include the high-grade Soto Norte gold project in Colombia and the Toroparu gold project in Guyana, where a Prefeasibility Study is in progress and a construction decision is expected in early 2027.

____________________

1 Reflects expected steady-state annual gold production of approximately 300 thousand ounces (koz) at Segovia and 200 koz at Marmato following completion and ramp-up of the respective expansion projects. For more information, please refer to the Company’s news releases dated June 30, 2025 regarding the Segovia expansion and March 12, 2025 regarding the Marmato expansion.

2 Includes potential production estimates from Toroparu, which is based on a preliminary economic assessment effective October 21, 2025, which contemplates a 7.0 Mtpa operation over a 21.3-year mine life with average annual gold production of approximately 235 koz at a base case gold price of US$3,000/oz. The preliminary economic assessment is preliminary in nature and 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 and to formal construction decisions by the Company, in each case for both Soto Norte and Toroparu.

Key Terms

dividend-adjusted share price performance financial

A measure of a stock's price performance that has been adjusted to reflect cash dividends paid to shareholders, usually by assuming dividends are reinvested in the stock or by adding their value back into the price series. It shows the total return from both price moves and dividend income, so investors can compare how much wealth an investment actually generated over time, similar to counting both salary and bonuses when judging pay growth.

prefeasibility study technical

A prefeasibility study is an early, high-level assessment that tests whether a proposed project is likely to be technically workable and economically viable before committing large resources. Like a rough blueprint and budget for a construction project, it provides preliminary estimates of costs, potential returns, key risks and data gaps so investors can decide whether to proceed to more detailed studies or funding.

ni 43-101 regulatory

A Canadian regulatory standard that sets the rules for how mining and exploration companies must report mineral resources and reserves, requiring technical reports prepared or signed off by an independent, certified expert. It matters to investors because it creates a consistent, transparent “inspection report” for mining projects, making it easier to compare prospects, judge the reliability of claims, and assess geological and financial risk before investing.

inferred mineral resources technical

An inferred mineral resource is an estimate of the quantity and grade of minerals in the ground based on limited sampling and geological information, where confidence is low and continuity is uncertain. For investors it signals potential value but also higher risk—like a rough sketch of a hidden treasure that requires much more exploration and testing before you can reliably judge its size or economic worth.

mineral reserves technical

Mineral reserves are the amounts of a metal or mineral that a company has identified and can legally and economically extract with current technology. Think of it like the usable fuel in a car’s tank rather than all the oil in the ground; reserves determine how long a mine can produce, help estimate future revenue and costs, and shape a company’s value and investment risk.
