Insights

Mining Industry Financial Analyst

Aris Mining's 13% H1 production growth and successful mill expansion strengthen 2025 outlook amid favorable gold prices.

Aris Mining's H1 2025 performance demonstrates robust operational momentum with gold production reaching 113,415 ounces, a 13% year-over-year increase. This growth trajectory is particularly significant as the company successfully commissioned its expanded Segovia mill in June 2025, a critical milestone that increases processing capacity to 3,000 tonnes per day.

The operational breakdown reveals compelling production trends across both mining assets. The Segovia Operations, representing approximately 87% of total production, delivered 99,076 ounces in H1, growing 12% compared to H1 2024. The smaller Marmato Narrow Vein Zone showed even stronger relative growth at 26%, contributing 14,339 ounces. This balanced growth across both operations indicates effective operational management and resource development.

Quarter-over-quarter performance shows continued positive momentum with Q2 production increasing 7% from Q1, while gold sales grew at an even stronger 12% rate. The operational metrics at Segovia reveal processing 9.61 g/t grade material with excellent 96.1% recoveries - both premium figures in the gold mining sector that contribute to favorable unit economics.

The on-time, on-budget delivery of the Segovia mill expansion represents a derisking event for Aris's growth strategy. With production expected to be weighted toward H2 2025 as the new mill ramps up, the company appears well-positioned to achieve its full-year guidance of 230,000 to 275,000 ounces. This increased production capacity, combined with the current strong gold price environment, suggests improved financial performance potential for the remainder of 2025.
