Aris Mining Corporation 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 TSX and NYSE under the symbol ARIS. Expansion projects underway at Segovia and Marmato are expected to increase production to approximately 500,000 ounces of gold per year driven by the ramp-up of the second mill at Segovia 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 existing portfolio supports a longer-term objective of approximately 1 million ounces of annual gold production.

The Company's principal product is gold doré. Aris Mining generates revenue primarily from the sale of gold doré to refiners with precious metals expertise. The gold market is relatively deep and liquid and is traded on a worldwide basis. As a result the Company is not dependent on a particular purchaser with regard to the sale of gold. The demand for gold is primarily for jewellery fabrication purposes and bullion investment and the price of gold is generally quoted in U. S. dollars.

The company operates through the following segments: Segovia Operations Marmato Mine Soto Norte Project Toroparu Project.

• Segovia Operations are located in the Segovia-Remedios mining district in the department of Antioquia Colombia approximately 180 km northeast of Medellín. The operations comprise four active underground gold mining operations which include El Silencio Sandra K Providencia and Carla together with other mineral resources and exploration targets a processing facility that processes both ore produced from the Property's mineral reserves and material that is mined by smaller groups outside of the Property titles tailings management facilities and numerous historical mines. The key title containing the majority of the Property's mineral resources and mineral reserves and key infrastructure Private Property Registry R140011 (RPP 140) was issued by the Ministry of Mines and Energy in 1998 and provides mining rights granted in perpetuity as long as exploitation occurs without a suspension of activities for a period of greater than one year.

• Marmato Mine is the gold-silver operation at Marmato Caldas Department Colombia comprising three contiguous properties: Zona Alta mining titles Zona Baja Mining Title and Echandia mining titles as more particularly described in the Marmato Technical Report including the currently operating Narrow Vein Zone the existing 1,200 tpd processing plant and the area encompassing the Narrow Vein Zone and Bulk Mining Zone. The Company is undergoing construction of the Bulk Mining Zone and CIP plant with first gold expected in Q4 2026.

• Soto Norte Project is a high-grade gold project in Santander Colombia where environmental studies are being finalized for submission in Q2 2026 to initiate the licensing process. The project is in the permitting stage and advancing environmental studies.

• Toroparu Project is an exploration-stage gold project in the Cuyuni-Mazaruni Region Guyana where a Prefeasibility Study is in progress and a construction decision is expected in early 2027. The project is based on a preliminary economic assessment 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.

The precious metal mineral exploration and mining business is a competitive business. The Company competes with numerous other companies and individuals in the search for and the acquisition of attractive precious metal mineral assets. The Company's ability to acquire precious metal mineral assets in the future will depend not only on its ability to develop its present properties but also on its ability to select and acquire suitable producing properties or prospects for precious metal development or mineral exploration.

The Company serves refiners with precious metals expertise. Aris Mining collaborates with small-scale miners known as contract mining partners to create mutually beneficial partnerships that support host communities. At Segovia and Marmato contract mining partners have long term contracts supplying mill feed to Aris Mining with payment based on gold content grade and the spot gold price. The contract mining partner workforce includes approximately 2,341 workers at the Segovia Operations and 129 workers at the Marmato Mine.
