Aris Mining Increases Segovia Gold Reserves by 28% to 1.9 Million Ounces

Aris Mining updated Segovia mineral reserve & resource estimates effective November 10, 2026.
Proven & probable mineral reserves increased 28% to 1.9 Moz gold, with net growth of 418 koz after accounting for mining depletion.
Measured & indicated mineral resources rose 8% to 3.9 Moz gold, while inferred resources decreased to 2.6 Moz due to high-grade conversion.
Proven & probable reserve grades increased 24% to 13.3 g/t Au, while measured & indicated resource grades rose 29% to 19.8 g/t Au.
CEO Neil Woodyer stated exploration & resource conversion programs are expanding the reserve base beyond simple replacement of mined ounces.
A gold price of US$2,800 per ounce was used for 2026 reserve estimates, while US$3,200 per ounce was applied to resource estimates.
The company is advancing the Toroparu prefeasibility study for release later in November 2026, marking the first reserve declaration for that project.
An updated NI 43-101 technical report for Marmato is expected in Q1 2027 following first gold from the new CIP plant.
Segovia's cash generation supports broader growth strategies, including expansion projects targeting 500,000 ounces annual production by late 2026.
Long-term portfolio objectives aim for approximately 1 million ounces annual production, including potential output from the Soto Norte & Toroparu projects.
