VANCOUVER, BC — January 8, 2026 — Leads & Copy — Aris Mining Corporation (TSX: ARIS) (NYSE-A: ARMN) has released updated mineral reserve and resource estimates for its Segovia project, effective Nov. 28, 2025.
The company reported a 7% increase in measured and indicated mineral resources, reaching 3.6 million ounces of gold, compared to 3.4 million ounces in the 2024 estimate. Inferred resources also saw a 12% increase to 2.9 million ounces.
Proven and probable mineral reserves increased by 12% to 1.5 million ounces, compared to 1.3 million ounces in the 2024 estimate. The company attributes this to the successful conversion of resources to reserves and ongoing mine development at Segovia.
According to the company, Segovia’s mineral inventory remains high-grade, with measured and indicated resources averaging 15.3 g/t Au and proven and probable reserves averaging 10.7 g/t Au.
Aris Mining CEO Neil Woodyer stated the updated estimates underscore the strength and durability of this exceptional high-grade asset. He noted that measured and indicated resources increased by 7%, inferred resources grew by 12%, and proven and probable reserves increased by 12%, or 160,000 ounces, net of mined depletion, reinforcing Segovia’s long mine life and supporting higher production rates following the mill expansion.
The company said it selected a gold price of $3,200 per ounce for mineral resources and $2,800 per ounce for mineral reserves, given the rapid and significant changes in the gold price over the past year.
To provide transparency, the company included a mineral resource sensitivity analysis across a wide range of gold prices, from $2,100 per ounce, consistent with the gold price used in the 2024 estimate, to the $3,200 per ounce selected for the 2025 estimate. The sensitivity analysis demonstrates that the Segovia mineral resource is largely insensitive to gold price assumptions, with measured and indicated contained gold ranging from 3.4 Moz to 3.6 Moz, reflecting the high-grade nature and strong underlying economics of the deposit.
Pamela De Mark, P.Geo., Senior Vice President of Geology and Exploration of Aris Mining, prepared the 2025 MRE. Miguel Marcelo Roldán, FAusIMM, Technical Services Manager, Segovia Operations, of Aris Mining, supervised and reviewed the 2025 mineral reserve estimate.
