Q1 2026 Financial Performance

Production of 74.3 thousand ounces (koz) of gold, up 6% from Q4 2025.
Gold revenue of $364 million, up 21% from Q4 2025.
Adjusted EBITDA¹ of $212 million, up 26% from Q4 2025. On a trailing 12-month basis, Adjusted EBITDA¹ of $610 million.
Adjusted net earnings of $124 million or $0.60/share, up from $0.46/share in Q4 2025.
Cash balance of $472 million as of March 31, 2026, up $80 million from December 31, 2025.
Net debt reduced to near zero.

Neil Woodyer, Chair and CEO, commented, "Supported by record financial results and strong cash generation from our operations, we advanced all four of our assets in Q1 2026. At Segovia, the ongoing ramp-up contributed to a 5% increase in production compared with Q4 2025. At Marmato, construction of the new 5,000 tonnes per day (tpd) CIP plant remains on schedule for first gold in Q4 2026, and the April 2026 decline breakthrough into the cross-cut marked an important milestone, providing direct access to the plant.

At Toroparu, the prefeasibility study is progressing well, with updated mineral resource and reserve estimates advancing to support mine schedule optimizations, and a construction decision is expected in early 2027. At Soto Norte, the submission of the environmental license application is nearing completion, alongside active engagement with the Colombian regulators to support a collaborative approach to the submission and review process.

With our producing assets delivering strong results and our growth projects continuing to advance, Aris Mining is well positioned to achieve its longer-term objective of approximately 1 million ounces of annual gold production.² With the right assets in place, we remain focused on executing and delivering against our plans."

Q1 2026 Operational Performance

Segovia produced 66.6 koz, a 5% increase over Q4 2025.
- Production reflected the processing of 175.4 thousand tonnes (kt) at 12.41 g/t, compared to 201.1 kt at 10.10 g/t in Q4 2025.
- AISC margin increased 31% to $199 million from Q4 2025, supported in part by a 23% increase in average mill feed grade.
- Owner-operated mining contributed 64% of the mill feed, while Contract Mining Partner (CMP) sourced mill feed contributed 36%, consistent with Q4 2025.
- Owner-operated mining AISC was $1,492/oz, compared to $1,662/oz in Q4 2025, outperforming the full-year 2026 guidance range of $1,700 to $1,800/oz, primarily reflecting a 14% increase in owner-mining attributable ounces sold, driven in part by higher average grades.
- CMP-sourced gold delivered an AISC sales margin of 40%, achieving the top-end of the full-year 2026 guidance range of 35% to 40%.
- Combined AISC was $1,963/oz, up 4% from $1,891/oz in Q4 2025, reflecting the factors driving Owner-operated mining and CMP AISC described above.

Marmato produced 7.8 koz, a 16% increase over Q4 2025.
- Production reflected the processing of 77.0 kt at 3.53 g/t, compared to 74.6 kt at 3.12 g/t in Q4 2025.
- This increased production reflects the operating capacity of the existing flotation plant together with mill feed sourced primarily from ore development and stopes in the Bulk Mining Zone.
- Throughput is expected to increase materially upon commissioning of the new Carbon-in-Pulp (CIP) plant later this year in the fourth quarter.
- 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 by the end of 2027 when the paste backfill plant is fully commissioned.

Project Development Highlights

Strong operating cash flow fully funded growth and generated $42 million in net cash flow
- In Q1 2026, operations generated $103 million in cash flow after sustaining capital and income taxes, fully funding the Company's growth and expansion initiatives. After expansion capital, Aris Mining generated net cash flow of $42 million. Refer to the cash-flow summary in the following sections and MD&A for additional analysis.
Marmato construction advancing on schedule
- The new underground decline has now broken through into the cross-cut, marking an important milestone that provides direct access from the Bulk Mining Zone to the new 5,000 tpd CIP plant. This connection establishes an additional access and ventilation pathway, facilitates ore and waste haulage between existing and new infrastructure, and supports 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, main pump station and field offices will begin in Q2 2026.
- First gold from the new CIP plant remains on schedule for Q4 2026.
Toroparu Project (100% owned, Guyana)
- Aris Mining initiated a Prefeasibility Study (PFS) last year, targeted for completion in H2 2026, to support a construction decision in early 2027.
- Work on updated mineral resource and reserve estimates is progressing well with mine scheduling and optimizations currently underway.
- Alongside the PFS, Aris Mining is also conducting geotechnical drilling, metallurgical test work, mining operation trade-off studies and detailed engineering to enable construction readiness by early 2027.
- Select pre-construction activities are continuing, including construction of the bridge at the Puruni River crossing, key personnel ramp up, camp expansion and ongoing road works.
- Preliminary Economic Assessment (PEA) completed in October 2025, outlining an attractive project with average annual gold production of 235 koz and 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)
- The studies required for submission of the environmental license application in support of the development of Soto Norte are nearing completion, supporting a targeted Q2 2026 submission.
- Aris Mining continues active engagement with the Colombian regulators to support a collaborative approach to the environmental license submission and review process.
- PFS completed in September 2025, demonstrating robust economics with average annual gold production (years 2 to 10) of 263 koz and 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 an IRR of 40%.
- The PFS incorporates industry-leading environmental and social design features, including a metallurgical process free of cyanide and mercury and 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.

The Company is advancing expansion projects at Segovia and Marmato that are expected to increase annual gold production to approximately 500,000 ounces ⁷, 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 portfolio supports a longer-term objective of approximately 1 million ounces of annual gold production². 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 to support a construction decision expected in early 2027.

Endnotes

1. All references to adjusted earnings, EBITDA, adjusted EBITDA, growth capital investment, cash flow after sustaining capital and income taxes, cash costs ($ per oz) and AISC ($ per oz) are non-GAAP financial measures in this document. These measures are intended to provide additional information to investors. They do not have any standardized meanings under IFRS, and therefore may not be comparable to other issuers and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. Refer to the Non-GAAP Measures section in this document for a reconciliation of these measures to the most directly comparable financial measure disclosed in the Company's financial statements.

2. Includes potential production estimates from Toroparu, which is based on a preliminary economic assessment effective October 21, 2025, which contemplates a 7.0 Mtpa operation over a 21.3-year mine life with average annual gold production of approximately 235 koz at a base case gold price of US$3,000/oz. The preliminary economic assessment is preliminary in nature and includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the preliminary economic assessment will be realized. Mineral resources that are not mineral reserves do not have demonstrated economic viability. There can be no assurance that the projected production will be achieved. In the case of Soto Norte and Toroparu, such production also remains subject to obtaining all necessary permits and to formal construction decisions by the Company.

3. Aris Mining operates its own mines and contracts with community-based mining partners, referred to as Contract Mining Partners or CMPs, to increase total gold production. Some partners work within Aris Mining's infrastructure, while others manage their own mining operations on Aris Mining's titles using their own infrastructure. In addition, Aris Mining purchases high grade mill feed from third-party contractors operating off-title, which further optimizes production and increases operating margins.

4. Net earnings represents net earnings attributable to owners of the company, as presented in the annual and interim financial statements for the relevant period.

5. See technical report dated October 28, 2025 and entitled "NI 43-101 Technical Report Preliminary Economic Assessment for the Toroparu Project Cuyuni-Mazaruni Region, Guyana". Note that this PEA is preliminary in nature. It includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the preliminary economic assessment will be realized. Mineral resources that are not mineral reserves do not have demonstrated economic viability.

6. See technical report dated September 3, 2025 and entitled "NI 43-101 Technical Report Prefeasibility Study for the Soto Norte Project, Santander, Colombia."

7. Reflects expected steady-state annual gold production run-rates of approximately 300 koz at Segovia and 200 koz at Marmato following completion and ramp-up of the respective expansion projects. For more information, please refer to the Company's news releases dated June 30, 2025 regarding the Segovia expansion and March 12, 2025 regarding the Marmato expansion.

Cash Cost and All-in Sustaining Cost

Cash costs per ounce, and all-in sustaining cost per ounce (as calculated in the tables above) are performance measures that reflect all the expenditures that are required to produce and sell an ounce of gold from operations. Management believes that these two measures are useful to market participants in assessing operating performance and the Company's ability to generate cash flow from current operations. These measures do not have standardized meanings under IFRS and may not be comparable to similar measures used by other issuers.

Operating Cash Flow and Free Cash Flow after Growth and Expansion Capital

Cash flow from operations after sustaining capital and income taxes is calculated as adjusted net cash provided by operating activities, less sustaining capital and income taxes paid. Free cash flow after growth and expansion capital is calculated by further deducting growth and expansion capital. Management believes these measures are useful to market participants in assessing the Company's ability to generate cash flow from operations after funding its capital requirements. These measures do not have standardized meanings under IFRS and may not be comparable to similar measures used by other issuers.

Growth and Expansion Capital

Growth and expansion capital represents additions to depletable and non-depletable mineral interests, right of use assets, exploration projects, and plant and equipment that are not sustaining in nature. Management believes this measure is useful to market participants in assessing the level of capital invested to expand operations, develop projects and support future growth separately from capital required to sustain current operations. This measure does not have a standardized meaning under IFRS and may not be comparable to similar measures used by other issuers.

EBITDA and Adjusted EBITDA

EBITDA is calculated as earnings before tax, adjusted to add back depreciation and depletion, finance income, and interest and accretion. Adjusted EBITDA is calculated by further excluding items that management does not consider to be reflective of the underlying operating performance. Management believes these measures are useful to market participants in assessing the Company's operating performance and ability to generate cash flow from operations. These measures do not have standardized meanings under IFRS and may not be comparable to similar measures used by other issuers.

Adjusted Net Earnings and Adjusted Net Earnings Per Share

Adjusted net earnings is calculated as net earnings attributable to owners of the Company, adjusted for items that management does not consider to be reflective of the underlying operating performance of the Company Adjusted net earnings per share is calculated by dividing adjusted net earnings by the basic weighted average number of shares outstanding for the applicable period. Management believes these measures are useful to market participants in assessing the Company's underlying financial performance and results on a per share basis. These measures do not have standardized meanings under IFRS and may not be comparable to similar measures used by other issuers.
