Aris Mining (ARIS) investor relations material

Strategic asset overview and expansion plans

• Operating two mines in Colombia, with two additional projects advancing toward development, aiming for up to 1 million ounces annual gold production in the future.

• Segovia ramp-up expected to complete by mid-next year; Marmato's new plant to pour first gold by year-end and reach full operation by early next year.

• Toroparu pre-feasibility to finish this quarter, with a construction decision targeted for early next year; Soto Norte redesigned and ready for environmental submission.

• All assets have mine lives exceeding 20 years, except for one, supporting long-term production stability.

Operational and community integration

• Segovia's expansion targets 300,000 ounces steady-state, with 30-35% of production from formalized small mining partners.

• Marmato's new CIP plant and flotation plant to boost output above 200,000 ounces, with potential for an additional 30,000-50,000 ounces from formalized miners.

• Over 4,000 small miners formalized, with plans to reach 8,000, providing social security, legal support, and community acceptance.

• Community engagement and formalization model expanded to all projects, fostering local support and reducing project risk.

Project development and government relations

• Toroparu's licensing and construction decision expected early next year, with environmental license already secured.

• Soto Norte's scale reduced for practicality and community acceptance, with a new mine plan and increased processing capacity for small miners.

• Recent government change in Colombia has led to increased ministerial support and a more mining-friendly environment.

• Multiple high-level meetings with new administration indicate strong intent to support mining sector reforms.
