Key Terms

carbon in pulp (CIP), AISC, g/t, koz

4 terms

carbon in pulp (CIP) technical

"start of production from the new Marmato carbon in pulp (CIP) plant."

Carbon-in-pulp (CIP) is an industrial method for recovering gold from crushed ore where gold dissolved in a liquid is captured by activated carbon particles suspended in the slurry, then separated for refining. Investors care because CIP affects how much gold a mine actually produces, the speed and cost of recovery, and environmental handling—like knowing whether a factory uses an efficient sponge to pull valuable metal out of a soup.

AISC financial

"AISC 5 (US$/oz) – Owner mining 6 | $1,700 to $1,800"

All-in Sustaining Cost (AISC) is a comprehensive measure of how much it costs a mining company to produce one unit of metal when ongoing operating expenses, long-term maintenance and sustaining capital, and share of corporate overhead are included. Investors use AISC to compare profitability and cash generation across producers—think of it as the full household cost to keep a business running divided by how many items it makes, which helps assess margins and resilience to price swings.

g/t technical

"Average gold grade processed (g/t) | 10.10 | 9.87 | 9.85 | 9.37 | 9.82"

g/t stands for grams per tonne, a measure of how many grams of a metal—most often gold or other precious metals—are contained in one metric tonne of rock or ore. Investors use it to judge how “rich” a mineral deposit is: higher g/t means more metal per amount of material to process, which can make mining cheaper and projects more likely to be profitable—like measuring teaspoons of sugar per cake to gauge sweetness value.

koz technical

"Gold production (koz) | 265 - 300 | 35 - 50 | 300 - 350"

koz stands for “thousand ounces,” a unit commonly used to report quantities of precious metals like gold and silver. Investors see production, reserves or sales quoted in koz so they can quickly gauge scale—similar to saying “thousand dollars” instead of single dollars—and estimate potential revenue by multiplying the number of koz by the market price per ounce. For metals, the ounces are usually troy ounces, the standard used in the industry.

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

VANCOUVER, BC, Jan. 21, 2026 /PRNewswire/ - 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.
• 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.

About Aris Mining

Founded in September 2022, Aris Mining was established with a vision to build a leading South America-focused gold mining company. The Company's strategy combines current production and cashflow generation with transformational growth driven by expansions of its operating assets, exploration, and development projects. Aris Mining intends to unlock value through scale, diversification and execution. The Company is listed on the TSX (ARIS) and the NYSE-American (ARMN) and is led by an experienced team with a strong track record of value creation, operational excellence, financial discipline and good corporate governance in the gold mining industry.

Aris Mining operates two underground gold mines in Colombia: Segovia and Marmato, which together produced 256,503 ounces of gold in 2025. With expansions underway, the Company is targeting an annual production rate of 500,000 ounces of gold, driven by the commissioning of a second mill at Segovia, completed in June 2025 and ramping up since, and the construction of the CIP plant at Marmato, with first gold expected in Q4 2026.

Beyond its operating assets, Aris Mining has a development pipeline that supports its longer-term growth outlook to achieve annual production of approximately 1.0 million ounces of gold⁸. In Guyana, Aris Mining owns the Toroparu gold project, where a Preliminary Economic Assessment was completed in October 2025 and a Prefeasibility Study is in progress, positioning the project to advance toward construction. In Colombia, Aris Mining also owns the high-grade Soto Norte gold project, where a Prefeasibility Study was completed in September 2025 that balances scale and strong economics with industry leading environmental and social design features. Environmental studies are being finalized and on schedule for submission in Q2 2026 to initiate the Soto Norte licensing process.
