2025 Financial Performance

• 2025 production of 256,503 ounces (oz) of gold, exceeding the guidance midpoint (230,000-275,000 oz), and a 22% increase from 210,955 oz in 2024.
• 2025 gold revenue of $909 million, up 82% from 2024.
• Adjusted EBITDA¹ of $464 million, up 185% from 2024.
• Adjusted net earnings of $241 million or $1.28/share, up 265% from $0.35/share in 2024.
• Cash balance increased to $392 million as of December 31, 2025, up from $253 million at December 31, 2024. This increase primarily reflects:
  • +$322 million of cash flow from operations after sustaining capital and income taxes;
  • +$115 million of proceeds from the exercise of ARIS.WT.A warrants (July 2025 expiry); and
  • +$13 million of proceeds from the sale of the Juby Gold Project; partially offset by
  • -$77 million of debt repayment and servicing;
  • -$60 million cash used for the Q4 2025 acquisition of the remaining 49% interest in Soto Norte; and
  • -$196 million invested in growth capital.
• Net debt reduced to $86 million, down from $241 million at year-end 2024.

Neil Woodyer, Chair and CEO, commented "During 2025, our operations generated $322 million of cash flow after sustaining capital and income taxes, fully funding our growth and expansion initiatives. After these investments, we generated $127 million in net cash flow, demonstrating the strong underlying cash generation of the business.

At Segovia, the ramp-up of the second mill is progressing well and contributed to record financial results during the year. At Marmato, development in the Bulk Mining Zone is ahead of schedule, materially reducing execution risk as we advance construction of the new carbon-in-pulp (CIP) processing facility, which remains on schedule for first gold in Q4 2026.

We also advanced our longer-term growth, completing the Soto Norte Prefeasibility Study (PFS) and the Toroparu Preliminary Economic Assessment (PEA) in September and October 2025, respectively. We remain on track to submit the environmental license application for Soto Norte in Q2 2026, while advancing Toroparu toward completion of its Prefeasibility Study in the second half of 2026 and a potential construction decision in early 2027.

With record revenue, operating cash flow and earnings since Aris Mining's formation in September 2022, we enter 2026 in a strong financial position and well placed to continue executing our growth strategy."

2025 Operational Performance

• Marmato produced 28,741 oz, a 23% increase over 2024 and above the 2025 guidance range (20,000-25,000 oz), supported by stable throughput and higher average gold grades. The 2025 results reflect the operating capacity of the existing flotation plant. Throughput is expected to increase materially upon commissioning of the new CIP plant later this year.
• Segovia produced 227,762 oz, a 21% increase over 2024 and achieving the 2025 guidance range (210,000-250,000). The 2025 performance reflects gold grades of 9.82 g/t, gold recoveries of 96.1%, and a 17% increase in tonnes milled compared to 2024, driven by the installation of a second ball mill in June 2025.
  • AISC margin increased to $420.8 million, up 158% from 2024.
  • Owner-operated Mining AISC was $1,534/oz compared to $1,486/oz in 2024, within the full-year 2025 guidance range of $1,450 to $1,600/oz.
  • Contract Mining Partner (CMP) sourced gold delivered an AISC sales margin of 44%, exceeding the full-year 2025 guidance range of 35% to 40%.
  • Total AISC of $1,705/oz compared to $1,507/oz in 2024. The 2025 results reflect disciplined cost control in owner-mining at $1,534/oz (up 3.2% over 2024). AISC for CMPs was $1,973/oz (up 29% over 2024), primarily reflecting the gold-price-linked purchase formula during a period when realized gold prices increased 48%.

Corporate and Project Development Highlights

• Strong cash generation funding growth:
  • Operations generated $322.1 million in cash flow after sustaining capital and income taxes in 2025, fully funding all growth and expansion initiatives. After expansion capital, Aris Mining generated $126.5 million in net cash flow. See the cash-flow summary in the following sections for additional cash flow analysis.
• 2026 Production and Cost Guidance⁴:
  • 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. The increase reflects higher expected production at Segovia and the start of production from the new Marmato CIP plant.
  • 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 mill feed from both owner-operated mining and CMP sourced material.
  • At Marmato, gold production is expected to increase to between 35,000 and 50,000 ounces, up from the 28,741 ounces in 2025. Production will be back-end weighted driven by the commissioning of the CIP plant, with first gold from the new plant expected in Q4 2026.

• Marmato construction advancing:
  • Development of the new underground decline to the Bulk Mining Zone is currently 60% complete (over 1,000 metres advanced) and is scheduled for completion in Q3 2026, ahead of CIP plant commissioning in Q4 2026. The new decline will significantly improve access and haulage efficiency, enabling higher mining rates and lower costs as processing capacity expands.
  • The new decline has advanced beyond the connection point to the underground crosscut, with completion of the crosscut expected in April 2026. This horizontal development, connecting the upper part of the Bulk Mining Zone with the main decline, will establish an additional access and ventilation pathway, facilitate ore and waste haulage between existing and new infrastructure, and support the initial ramp up of mine production.
  • The main civil, mechanical, and electrical works are advancing, with foundations for the mills, tailings thickener, and leach and CIP tanks completed.
  • Construction of underground workshops and ore storage, main pump station and field offices will begin in Q2 2026.
  • Subsequent to December 31, 2025, the Company received the $40 million instalment deposit under its precious metals stream financing following achievement of the 50% completion milestone. The proceeds will be recognized in the first quarter of 2026. The remaining $42 million instalment deposit is payable upon achievement of the 75% completion milestone.
  • During most of 2026, owner mining rates are expected to average approximately 900 tonnes per day (tpd), reflecting the throughput capacity of the existing flotation plant, sourced primarily from ore development and stopes in the Bulk Mining Zone.
  • 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.

• Toroparu Project (100% owned, Guyana):
  • Aris Mining initiated a PFS last year, targeted for completion in 2026, to advance Toroparu toward a construction decision in early 2027.
  • The Company commenced select pre-construction activities, which includes building a bridge at the Puruni river crossing and ongoing road construction.
  • Preliminary Economic Assessment (PEA) completed in October 2025, outlining an attractive project with an after-tax NPV_5% of $1.8 billion, IRR of 25%, and 3.0-year payback at an assumed gold price of $3,000/oz.⁵

• Soto Norte Project (100% owned, Colombia):
  • Aris Mining is finalizing the required studies to apply for an environmental license in Q2 2026 for the development of Soto Norte.
  • Prefeasibility Study (PFS) completed in September 2025, demonstrating robust economics with an after-tax NPV_5% of $2.7 billion, IRR of 35%, and 2.3-year payback at an assumed gold price of $2,600/oz.⁶
  • Strong leverage to higher gold prices, at $3,000/oz the NPV_5% increases to $3.3 billion with IRR of 40%.
  • The PFS incorporates industry-leading environmental and social design features, including the integration of local community miners – 750 tpd (over 20% of Soto Norte's 3,500 tpd processing capacity) has been dedicated to local contract mining partners.

About Aris Mining

Aris Mining is a Canadian gold mining company focused on South America. The Company operates the Segovia and Marmato underground gold mines in Colombia, which together produced approximately 257,000 ounces of gold in 2025. Aris Mining is listed on the TSX and NYSE under the symbol ARIS.

Expansion projects underway at Segovia and Marmato are expected to increase production to approximately 500,000 ounces of gold per year, driven by the ramp-up at Segovia following the installation of the second mill, which was completed in June 2025, and construction of the new Marmato bulk mine and CIP plant, with first gold expected in Q4 2026.

Aris Mining's existing portfolio supports a longer-term objective of approximately 1 million ounces of annual gold production⁷. Key projects include the high-grade Soto Norte gold project in Colombia, where environmental studies are being finalized for submission in Q2 2026 to initiate the licensing process, and the Toroparu gold project in Guyana, where a Prefeasibility Study is in progress and a construction decision is expected in early 2027.
