Read MoreHide Full Article
Key Takeaways
Aris Mining's Q3 2025 AISC climbed, with Segovia costs rising to $1,641 per ounce year over year.
ARMN saw higher costs from mill feed purchases, royalties and ramp-up of Segovia's second mill.
Aris Mining's AISC margin improved sharply on higher gold prices and increased sales volumes.
Aris Mining Corporation (ARMN - Free Report) is plagued by elevated cost pressures. In the third quarter of 2025, ARMN reported an increase in its all-in-sustaining costs (AISC) per ounce, a key indicator of cost efficiency in mining. The Segovia Operations in Colombia, a cornerstone of Aris Mining's portfolio, reported AISC of $1,641 per ounce, up from $1,540 in the year-ago quarter, due to higher sustaining capital expenditures. The company’s consolidated AISC increased 6.6% year over year to roughly $1,641 per ounce.
The increase in ARMN’s costs in the third quarter was mainly due to higher volumes of purchased mill feed from Contract Mining Partners, as well as increased royalty and social contribution expenses tied to higher gold prices and stronger sales volumes. Mining costs also rose as a result of greater throughput and the ramp-up of operations following the commissioning of the second mill at Segovia.
Despite these headwinds, Aris Mining’s profitability remains resilient. The company’s AISC margin stayed strong, rising 36% sequentially and 42% year over year in the third quarter. This improvement was supported by higher realized gold prices and increased sales volumes, which significantly boosted gold revenues.
While Aris Mining’s expenses are increasing, they are mainly tied to strategic, growth-oriented initiatives. Supported by rising gold prices, increasing output and disciplined cost management, the company is well-positioned to sustain healthy margins and continue executing its long-term growth strategy.
AISC of ARMN’s Peers
Among ARMN’s major peers, Agnico Eagle Mines Limited’s (AEM - Free Report) AISC was $1,373 per ounce in the third quarter of 2025, increasing 7% year over year. Agnico Eagle forecasts total cash costs per ounce in the range of $915-$965 and AISC per ounce between $1,250 and $1,300 for 2025, suggesting a year-over-year increase at the midpoint of the respective ranges. While Agnico Eagle is taking actions to control costs, the inflationary pressure is likely to continue over the near term, weighing on its profit margins and overall financial performance.
ARMN’s another peer, Newmont Corp. (NEM - Free Report) reported AISC for gold of $1,566 per ounce in the third quarter of 2025, down around 2.8% year over year. However, Newmont expects gold AISC for the total portfolio to be $1,630 per ounce in 2025, reflecting a year-over-year rise. The benefits of Newmont’s cost-saving actions are expected to be more than offset by higher royalties, production taxes and costs from profit-sharing agreements.
