ARIS MINING COMPLETES INSTALLATION AND COMMISSIONING OF SECOND MILL AT SEGOVIA, ON TIME AND ON BUDGET

Aris Mining Corp. has successfully installed and commissioned a second processing mill at its high-grade Segovia operations in Antioquia, Colombia. This expansion is a significant milestone in the company's organic growth strategy and increases Segovia's processing capacity by 50 per cent, from 2,000 to 3,000 tonnes per day (tpd).

To mark the occasion, Aris Mining has released a short video highlighting key milestones during the mill installation.

The second mill is fully integrated into the existing plant infrastructure and utilizes shared circuits for crushing, flotation, leaching and tailings filtration. The project was completed on schedule and within budget, with commissioning activities completed in June 2025.

Neil Woodyer, chief executive officer, commented: "The installation and commissioning of the second mill at Segovia, which began operating last week, is another important step in advancing our growth strategy to reach an aggregate production rate of more than 500,000 ounces annually from our wholly owned Segovia operations and Marmato complex. Segovia's expanded capacity is expected to steadily increase gold production in the second half of 2025, with full-year 2025 gold production expected to be in the range of 210,000 to 250,000 ounces, up from 187,583 ounces produced in 2024. As underground development advances and mill feed purchases from our contract mining partners grow, Segovia is on track to achieve annual production of 300,000 ounces next year. Segovia is a cornerstone asset for Aris Mining, and this expansion further strengthens its role as a key cash flow generator."
