FOLLOWING SECOND MILL COMMISSIONING IN LATE JUNE
Vancouver, Canada, September 5, 2025 – Aris Mining Corporation (Aris Mining or the Company) (TSX: ARIS; NYSE -

a second mill in June 2025. The expanded processing capacity has already delivered a substantial increase in mill
throughput and gold production.

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.
