Aris Mining Corporation (ARMN) was upgraded to a Zacks Rank #1 (Strong Buy) on January 15, 2026. This upgrade reflects a consensus expectation for above-average earnings revisions over the next 60 days. Zacks analysts pointed to a recent upward revision in first-quarter production guidance, with output forecasts rising by 8% compared to the prior estimate, as the primary catalyst for the new ranking.

ARMN now projects first-quarter gold equivalent production of 42,000 to 45,000 ounces, up from an earlier range of 38,500 to 42,000 ounces. Management attributes the increase to higher mill throughput rates at its flagship Cerro Verde project and results from a recently commissioned intake pump that has boosted underground access. Analysts polled by Zacks have raised consensus earnings estimates for Q1 by 12% to $0.18 per share.

On the same day as its Zacks upgrade, ARMN was named one of the top momentum stocks for January 15, 2026. The designation follows a 9% share-price gain over the prior month, outpacing the 4% average gain in the gold mining peer group. Trading volume has climbed 60% above its 30-day average, indicating growing investor interest in the company’s near-term growth story.

Key drivers for ARMN’s near-term performance include ongoing drill results from its South Puma project, scheduled for release in early February, and the planned expansion of its flotation circuit, which could increase recovery rates by up to 4 percentage points. Potential headwinds include rising diesel costs, which represent approximately 15% of operating expenses, and a possible delay in securing regulatory approval for the flotation circuit expansion.
