Aris Mining (NYSE: ARMN) lifts 2025 gold production 22% and guides higher for 2026

Rhea-AI Filing Summary

Aris Mining reported 2025 gold production of 256,503 ounces, up 22% from 210,995 ounces in 2024, driven mainly by the expanded Segovia mill and strong performance at Marmato. Fourth quarter 2025 output was 69,852 ounces, with Segovia contributing 63,137 ounces and Marmato 6,715 ounces, and total 2025 gold sales reaching 260,023 ounces.

For 2026, the company guides consolidated production to 300,000–350,000 ounces, including 265,000–300,000 ounces from Segovia and 35,000–50,000 ounces from Marmato. Segovia’s 2026 cash costs are forecast at $1,150–$1,250 per ounce and all-in sustaining costs at $1,700–$1,800 per ounce, based on a gold price of $4,400 per ounce and a 3,800 Colombian peso exchange rate.

The company highlights growth projects at Segovia and Marmato targeting a 500,000-ounce annual production rate and a longer-term goal of approximately 1.0 million ounces per year, which depends on advancing the Toroparu and Soto Norte projects, completing technical studies, obtaining permits and realizing preliminary economic assessments that currently include inferred resources without demonstrated economic viability.

Insights

Mining equity analyst

Production rose 22% in 2025 and 2026 guidance signals further growth.

Aris Mining delivered 2025 gold production of 256,503 ounces, a 22% increase from 210,995 ounces in 2024, driven by the expanded Segovia mill and steady Marmato output. Q4 2025 production of 69,852 ounces shows the assets operating at a higher run-rate than early in the year, supported by strong recoveries around 96.1% at Segovia and 90.6% at Marmato.

For 2026, the company guides consolidated production to 300,000–350,000 ounces, with Segovia at 265,000–300,000 ounces and Marmato at 35,000–50,000 ounces. Segovia’s cash cost guidance of $1,150–$1,250 per ounce and AISC of $1,700–$1,800 per ounce are based on a gold price of $4,400 per ounce and a 3,800 exchange rate, framing expected unit economics under those assumptions.

The narrative also outlines a path toward a 500,000-ounce annual rate from expansions at Segovia and Marmato and a longer-term target of about 1.0 million ounces per year including Toroparu and Soto Norte. These larger growth figures rely on preliminary economic assessments, inferred resources and future permitting, so actual outcomes depend on successful studies, regulatory approvals and project execution over time.

ARIS MINING DELIVERS STRONG 2025 GOLD PRODUCTION ABOVE GUIDANCE
MID-POINT AND OUTLINES ACCELERATING GROWTH INTO 2026

2026 production expected to rise to 300,000–350,000 ounces, driven by
Segovia ramp-up and Marmato expansion

Vancouver, Canada, January 21, 2026 – Aris Mining Corporation (Aris Mining or the Company) (TSX: ARIS; NYSE-A: ARMN) reports gold production of 256,503 ounces (oz) for the full year ended December 31, 2025, representing a 22% increase over 2024 production of 210,995 oz, driven by the expanded Segovia mill and above-guidance performance at Marmato. Fourth quarter production of 69,852 oz capped off a year of strong operational execution.

2025 Gold Production Highlights:

· 2025 production of 256,503 oz, exceeding the guidance midpoint (230,000-275,000 oz).

· H2 2025 production of 143,088 oz, up 26% over H1 2025, reflecting the installation of Segovia’s second ball mill in June 2025.

· Cash balance of over US$390 million¹ at December 31, 2025, net of the US$60 million cash used for the Q4 2025 acquisition of the remaining 49% interest in Soto Norte.

Neil Woodyer, CEO of Aris Mining, commented “2025 was a pivotal year for Aris Mining. The successful expansion and on-going ramp-up at Segovia drove 26% production growth in the second half of the year, while Marmato delivered steady, above-guidance results as underground development progressed and construction of the new CIP plant and related infrastructure advanced on schedule. Q4 2025 production at Segovia was modestly lower than Q3 due to unscheduled maintenance in November, and normal operations resumed in December. We exited 2025 with strong momentum and a clear growth pipeline as we build a diversified, multi-asset gold producer with the potential to reach one million ounces of annual production, including Toroparu and Soto Norte².

Looking ahead to 2026, we expect consolidated production of 300,000 to 350,000 oz, supported by continued ramp-up at Segovia and increasing production from Marmato from Q4 2026 onwards, where active mining in the wider porphyry areas is already underway, materially de-risking the project.”

2026 Gold Production and Cost Guidance:

Consolidated Production

· Aris Mining expects consolidated gold production in 2026 to range between 300,000 and 350,000 oz, with production weighted toward the second half of the year, reflecting higher production at Segovia and the start of production from the new Marmato carbon in pulp (CIP) plant.

Segovia

· At Segovia, gold production is expected to increase to between 265,000 and 300,000 ounces, up from the 227,762 ounces produced in 2025 and supported by higher output from both owner-operated mining and contract mining partner (CMP) sourced material.

Marmato

· At Marmato, gold production is expected to increase to between 35,000 and 50,000 ounces, up from the 28,741 ounces produced in 2025 and reflecting a back-end-weighted production profile driven by the commissioning of the CIP plant, with first gold from the CIP plant expected in Q4 2026.

· Approximately 5,000 ounces are expected to be contributed by CMPs operating in the Narrow Vein Zone. The balance of production will be generated by owner mining, primarily from ore development and stopes in the Bulk Mining Zone initiated in 2025 through existing decline access to the Bulk Mining Zone, materially reducing execution risk. The remaining work is focused on completion and commissioning of the new CIP plant.

 - 2 -

 

· During most of 2026, owner mining rates are expected to average approximately 900 tpd, reflecting the throughput capacity of the existing flotation plant.

· Development of the new underground decline to the Bulk Mining Zone is currently 45% complete (770 metres advanced) and is scheduled for completion in Q3 2026 ahead of CIP plant commissioning. The new decline will significantly improve access and haulage efficiency, enabling substantially higher mining rates and lower costs as processing capacity expands. An underground crosscut connecting to the new decline is expected to be complete in Q2 2026 providing additional access to the Bulk Mining Zone and positioning the mine for a smooth production profile increase.

· The new CIP plant is expected to be commissioned in Q4 2026 and will initially process all mined material. Aris Mining plans to exit 2026 operating the 5,000 tpd design capacity CIP plant at approximately 3,000 tpd. Production is expected to increase through 2027, with throughput increasing to approximately 4,000 tpd by mid-2027 and reaching the full 5,000 tpd design capacity by the end of 2027 when the paste backfill plant is fully commissioned.

· The Company expects to resume providing cash cost and AISC guidance for Marmato once the CIP plant reaches commercial production.
