ARISMINING REPORTS Q1 2026 RESULTS

RecordRevenue, Cash Flow, and Adjusted Earnings with All Four Assets Advancing

Vancouver,Canada, May 6, 2026 – Aris Mining Corporation (Aris Mining or the Company) (TSX: ARIS; NYSE: ARIS) announces its financial and operating results for the three months ended March 31, 2026 (Q1 2026). All amounts are in U.S. dollars unless otherwise indicated.

Q12026 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 EBITDA^1^ of $212 million, up 26% from Q4 2025. On a trailing 12-month basis,<br> Adjusted EBITDA^1^ 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.”

AboutAris 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 production^2^. 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.

CashCost 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.

OperatingCash 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.

Growthand 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.

EBITDAand 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.

AdjustedNet 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.
