ARIS MINING ANNOUNCES STEADY RAMP-UP AT SEGOVIA FOLLOWING SECOND MILL COMMISSIONING IN LATE JUNE
VANCOUVER, BC, Sept. 5, 2025 /CNW/ - Aris Mining Corporation (Aris Mining or the Company) (TSX: ARIS) (NYSE-A: ARMN) reports strong progress with the ramp-up at its Segovia Operations following successful commissioning of a second mill in June 2025. The expanded processing capacity has already delivered a substantial increase in mill throughput and gold production.
Key highlights:
- The second mill was successfully commissioned in late June 2025, on time and within budget, increasing installed processing capacity by 50% from 2,000 tonnes per day (tpd) to 3,000 tpd.
- Milling rates increased sharply in July and August, averaging 2,415 tpd, compared to 1,971 tpd over the six months ended June 30, 2025. In August, throughput also reached approximately 3,000 tpd on several days, demonstrating strong operating performance at design capacity.
- Processed gold grades averaged 10.02 g/t Au in July and August, which reflects disciplined use of the additional processing capacity and production growth without compromising grade.
- Year-to-date gold production at Segovia to August 31, 2025 totals 141,893 ounces, including 42,817 ounces produced in July and August.
In addition, the Marmato Narrow Vein zone contributed 4,936 ounces in July and August, bringing consolidated year-to-date gold production to 161,168 ounces. Aris Mining remains on-track to achieve its full-year 2025 production guidance of 230,000 to 275,000 ounces.
