Aris Mining is a company incorporated under the laws of the Province of British Columbia, Canada. The address of the Company’s registered and records office is 2900-550 Burrard Street, Vancouver, British Columbia, V6C 0A3.

Founded in September 2022, Aris Mining was established with a vision to build a leading South America-focused gold mining company. Our strategy blends current production and cash flow generation with transformational growth driven by expansions of our operating assets, exploration and development projects. Aris Mining is listed on the TSX (ARIS) and the NYSE-A (ARMN) and is led by an experienced team with a 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: the Segovia Operations and the Marmato Complex, which together produced 210,955 ounces of gold in 2024. With expansions underway, Aris Mining is targeting an annual production rate of more than 500,000 ounces of gold, following the commissioning of the second mill at Segovia, completed in June and ramping up in H2 2025, and the construction of the Bulk Mining Zone at the Marmato Complex, expected to start ramping up production in H2 2026. In addition, Aris Mining operates the 51% owned Soto Norte Project (PSN) in Colombia, where a Prefeasibility Study (PFS) is complete on a new, smaller scale development plan which confirms Soto Norte as a high-quality, long-life project with robust economics and industry-leading environmental and social design features. In Guyana, Aris Mining owns the Toroparu gold project, where a new Preliminary Economic Assessment (PEA) is complete and a PFS is underway.

Colombia is rich in high-grade gold deposits and Aris Mining is actively pursuing partnerships with the Country’s dynamic small-scale mining sector. With these partnerships, we enable safe, legal, and environmentally responsible operations that benefit both local communities and the industry, while strengthening operational stability for the Company. Guyana's mining sector is advancing rapidly as a new frontier for large-scale, responsibly developed projects with an attractive regulatory and investment environment.

•Marmato Bulk Mining Zone construction advancing

▪Development of the main access decline has advanced 580 metres of the planned 1.7 kilometres. Current development rates average 72 metres per month and are expected to increase to approximately 150 metres per month once beyond the fault zone, with completion of the full decline length targeted for August 2026.

▪The Los Indios crosscut is advancing toward its connection with the main decline, now approximately 320 metres away. This horizontal development will provide an additional access and ventilation pathway, enable ore and waste haulage between existing workings and new infrastructure. Importantly, completion of the crosscut will enhance operational flexibility and de-risk the project’s ramp-up phase by allowing multiple access points for early development and production sequencing.

▪Surface construction activities continue to advance safely, with over 2.06 million workhours completed to date. Bulk earthworks for the process plant platform have reached 95% completion (294,000 m³ moved), and the retaining wall is over 75% complete. Final shaping of the carbon-in-pulp (CIP) plant platforms is expected during the first week of November 2025.

▪Major equipment, including the primary crusher, SAG mill, ball mill, and filter press, has arrived in Cartagena. Approximately 95% of long-lead items have been ordered. The contract for the main civil, mechanical, and electrical works is in place, with the contractor mobilized and construction activities commenced in October.

▪Preparations for the new powerline continue to advance. Land acquisition is complete, and the environmental impact study has been submitted for approval, enabling construction to commence in March 2026 following permit issuance. To ensure continuity of commissioning and early operations, back-up generators are included in the site power plan to mitigate any potential delays in the grid power connection.

▪During Q2 and Q3 2025, we invested $20.1 million and $23.9 million, respectively, toward the construction budget.

▪At the end of Q3, the estimate to complete the project was $250 million, reflecting approximately $40 million of progress made over the six-month period since the prior estimate of $290 million at the end of Q1, which had incorporated the scope increase from 4,000 to 5,000 tpd.

▪Net of the remaining $82 million of stream financing payments to be received from Wheaton Precious Metals, the construction funding requirement is approximately $168 million.

▪The project remains on schedule, with first gold in H2 2026, followed by a production ramp-up period to steady-state operations.

2 See Technical Report entitled “NI 43-101 Technical Report Prefeasibility Study for the Soto Norte Project, Santander, Colombia” dated September 3, 2025.

Over the last eight quarters, income from mining operations has ranged from $25.3 million to a high of $122.7 million achieved in Q3 2025, EBITDA has ranged from $19.7 million to a Q3 2025 high of $96.5 million. The increased earnings were primarily driven by higher realized gold prices and stronger quarterly gold sales volumes, with Q3 2025 sales volumes reaching 73,001 ounces, the highest over that eight quarter period. Total revenue in Q3 2025 reached a record $258.1 million, a 27% increase from the previous high of $203.5 million in Q2 2025.

Current quarter income from mining operations of $122.7 million was up 33% from $92.0 million in Q2 2025, and 223% higher than the $38.0 million in Q3 2024. EBITDA was $96.5 million, up $65.0 million from Q2 2025 reflecting increased income from mining operations and decreased financial instrument losses. Financial instrument losses in Q2 2025 included a $45.5 million non-cash loss from the fair value adjustment on the Company's warrant liability, which was fully extinguished as of July 29, 2025. The Q3 2025 loss recorded from warrant liability fair value adjustments was $6.4 million. The Company also reported record Adjusted EBITDA of $131.1 million in Q3 2025, a 33% increase from the $98.7 million earned in Q2 2025.

Net earnings (loss) were $42.0 million in Q3 2025, up from net loss of $(16.9) million in Q2 2025, due to higher income from operations and a lower loss on financial instruments, partially offset by a higher income tax expense. Adjusted earnings improved to $71.8 million ($0.36 per share), up from $47.8 million ($0.27 per share) in Q2 2025, demonstrating strong underlying operational performance and a favourable gold price environment.

1.This Quarterly Cash Flow Summary is comprised of certain Non-GAAP financial measures. Refer to the Non-GAAP Financial Measures section of this MD&A for further information.

2.As presented in the Financial Statements and notes for the respective periods.

After-tax adjusted sustaining margin was $90.8 million in Q3 2025, compared to $73.8 million in Q2 2025, driven by the following factors:

•AISC margin increased $32.8 million or 36% as a result of a higher realized gold price of $3,472 per ounce as well as a 20% increase in gold ounces sold (73,001 ounces in Q3 2025 vs. 61,024 ounces in Q2 2025) primarily due to the ramp up of operations following the successful commissioning of the second mill at Segovia.

•VAT receivable build-up of $16.0 million in Q3 2025, compared to a net VAT recovery of $30.8 million recognized in Q2 2025, reflecting the annual VAT filing and recovery process completed during Q2 2025.

•Taxes paid totaled $13.2 million in Q3 2025, compared to $42.2 million in Q2 2025. Taxes paid in Q2 2025 included the settlement of the 2024 Colombia income tax liability.

•Other working capital movements reflected a build-up of accounts receivable due to higher gold revenues, consistent with normal collection timing differences.

After-tax adjusted sustaining margin increased to $90.8 million in Q3 2025 from $15.9 million in Q3 2024, driven by the following factors:

•AISC margin increased $83.6 million due to a 42% increase in realized gold price and a 36% and 30% increase in gold ounces sold at Segovia and Marmato, respectively.

•VAT receivable increased $16.0 million in Q3 2025, consistent with an increase of $11.4 million in Q3 2024. VAT is filed on an annual basis which was completed in Q2 2025 and Q4 2024 for their respective years.

•Taxes paid totaled $13.2 million in Q3 2025, primarily reflecting 2025 income tax installment payments compared to $4.7 million in Q3 2024.

•Other working capital movements resulted in an outflow of $0.3 million in Q3 2025, compared to $3.8 million in Q3 2024, primarily reflecting normal timing differences in the settlement of receivables and payables.

After-tax adjusted sustaining margin increased to $196.3 million in 2025 from $15.9 million in 2024, driven by the following factors:

•AISC margin increased 191%, contributing an additional $182.9 million compared to the prior year. The increase reflects a higher realized gold price of $3,228 per ounce as compared to $2,272 per ounce in 2024 and a 22% increase in gold ounces sold.

•Changes in the VAT receivable balance resulted in recoveries of $3.0 million in 2025, compared to a $28.9 million build up in 2024, reflecting timing differences in VAT recoveries, as the 2023 VAT filing was not completed until Q4 2024.

•Taxes paid totaled $60.6 million in 2025, compared to $13.2 million in 2024. The increase reflects the timing of income tax payments, as the 2023 Colombia income tax liability was not settled until Q4 2024.

•Other working capital movements resulted in an outflow of $13.7 million in 2025, compared to $24.6 million outflow in 2024. The prior year’s movements primarily reflected timing changes in accounts payable and accrued liabilities.

Growth and expansion capital expenditures were directed toward key development priorities:

•Marmato Bulk Mining Zone: $31.4 million was invested in Q3 2025 and $84.7 million year-to-date to advance underground development, including main decline advancement (580 meters completed of the planned 1.7 kilometers), progression of the Los Indios crosscut connection, earthworks for the CIP plant platforms (95% complete). Major equipment deliveries included the primary crusher, SAG mill, ball mill, and filter press, with approximately 95% of long-lead items ordered.

•Segovia Operations: $9.6 million in Q3 2025 and $22.9 million year-to-date were spent on underground mine development and exploration, installation and commissioning activities related to the Segovia mill expansion, which was commissioned in June 2025, as well as ongoing work on the tailings storage facility.

•Toroparu and Soto Norte: $7.1 million was invested in Q3 2025 and $20.3 million year-to-date on technical studies.

Financing and other net cash flows resulted in a net inflow of $65.1 million during Q3 2025 and $96.9 million in YTD 2025:

•ARIS.WT.A Listed Warrant and option exercises generated $59.8 million in net proceeds in Q3 2025 for a total of $122.7 million in 2025.

•Gold Note principal repayments totaled $4.1 million in Q3 2025 and $12.1 million in YTD 2025.

•Gold Note premium and interest payments totaled $6.2 million in Q3 2025 and $17.0 million in YTD 2025.

•2029 Senior Note interest payments were nil in Q3 2025 and $18.0 million YTD 2025.

The Company remains focused on disciplined capital deployment. Strong cash flow generation and cash position continue to support its capital investment programs while maintaining balance sheet flexibility.

The Segovia Operations are 100% owned by the Company and located in a historic mining district of Colombia. The operations include four underground mines and two processing facilities:

•A conventional processing facility, which produces doré, was expanded from 2,000 to 3,000 tpd in June 2025, with ramp-up advancing in line with expectations.

•A 200 tpd polymetallic processing plant that recovers lead and zinc concentrates from process tailings.

•Year-to-date 2025, approximately 40% of the gold sold was produced from mill feed purchased from CMPs, sourced from both within and outside of the Company’s mining titles.

Gold production totaled 65,549 ounces, up 27% as compared to Q2 2025. This performance was primarily driven by higher mill throughput, with average daily milling rates increasing by 31%, to 2,553 tpd in Q3 2025, compared to 1,976 tpd in Q2 2025, following the successful commissioning and steady ramp-up of the second mill. Gold grades in Q3 2025 averaged 9.87 g/t, consistent with Q2 2025, reflecting disciplined use of the additional processing capacity and production growth without compromising grade.

Gold production increased by 38% compared to Q3 2024, driven by a 32% increase in tonnes processed due to the successful commissioning of the second ball mill and a 7% improvement in average gold grades.

Gold production totaled 164,625 ounces, an increase of 21% compared to 136,106 ounces in 2024. The improvement reflects a 16% increase in milling rates, following the successful commissioning of the second mill in June 2025, along with higher average gold grades of 9.71 g/t compared to 9.26 g/t in 2024.

Gold revenue in Q3 2025 was $229.1 million, up 29% from Q2 2025, reflecting a 6% increase in average realized gold prices and a 22% increase in gold ounces sold.

Gold revenue increased 94% compared to Q3 2024, driven by a 42% increase in average realized gold prices and a 36% increase in gold ounces sold.

Gold revenue totaled $542.0 million YTD 2025, up 74% from $311.8 million YTD 2024, reflecting a 43% increase in the average realized gold price to $3,251 per ounce and a 22% increase in gold ounces sold.

•Owner Mining: Cash costs averaged $999 per ounce, down 8% from $1,081 per ounce in Q3 2024, reflecting higher production and sales volumes.

•CMPs: Cash costs rose 17% to $1,653 per ounce, compared to $1,417 per ounce in Q3 2024. The increase reflects higher prices for purchased mill feed, consistent with the increase in average realized gold prices, as CMP payments are linked to prevailing market prices.

Combined Owner Mining and CMP cash costs at Segovia averaged $1,256 per ounce for the nine months ended September 30, 2025, compared to $1,239 for the same period in 2024, remaining broadly consistent year-over-year.

•Owner Mining: Cash costs decreased to $1,048 per ounce in 2025 from $1,162 per ounce in 2024 primarily due to a 53% increase in gold ounces sold, which improved from 65,580 to 100,632 ounces.

•CMPs: Cash costs increased 20% to $1,575 per ounce, compared to $1,309 per ounce in 2024. The increase primarily reflects higher gold prices which increased 43% compared to 2024.

AISC at the Segovia Operations, combining Owner Mining and CMPs, averaged $1,641 per ounce in Q3 2025, a 2% decrease from $1,681 per ounce in Q2 2025. The reduction primarily reflects higher gold ounces sold, partially offset by an increase in royalties and social contributions.

AISC margin was $121.5 million, up 39% from $87.2 million in Q2 2025, supported by an increase in gold ounces sold and a higher realized gold price.

•Owner Mining: AISC averaged $1,452 per ounce, down 4% from $1,520 per ounce in Q2 2025 primarily due to higher gold ounces sold. Owner Mining AISC margin rose 44% to $83.1 million, benefiting from stronger gold prices and improved sales volumes.

•CMPs: AISC averaged $1,955 per ounce, slightly higher than $1,931 per ounce in Q2 2025. AISC margin for CMPs remained broadly consistent with the prior quarter, delivering a 44% sales margin.

Combined AISC at Segovia increased 7% to $1,641 per ounce, compared to $1,540 per ounce in Q3 2024, primarily due to higher CMP mill feed costs, royalties, and social contributions which are linked to gold prices as well as increased sustaining capital. Despite the increase in AISC, higher average realized gold prices and an increase in gold ounces sold resulted in a combined AISC margin of $121.5 million, up from $44.1 million in Q3 2024.

•Owner Mining: AISC averaged $1,452 per ounce, consistent with Q3 2024, reflecting per ounce cost decreases from increased ounces sold being largely offset by higher sustaining capital as well as the impact of higher realized gold prices on royalties and social contributions. Owner Mining AISC margin increased to $83.1 million, up significantly from $23.1 million in the prior-year quarter.

•CMPs: AISC increased 21% to $1,955 per ounce, compared to $1,622 per ounce in Q3 2024 primarily due to higher CMP mill feed costs. CMP AISC margin improved by $17.4 million as compared to the prior year quarter primarily due to higher realized gold prices.

Combined AISC at Segovia averaged $1,634 per ounce in YTD 2025, up 8% from $1,515 per ounce in YTD 2024. The increase was primarily driven by higher CMP mill feed costs, royalties, and social contributions, all of which increased with the rise in gold prices.

Despite the increase in AISC, AISC margin more than doubled, reaching $269.6 million, compared to $104.7 million in 2024, reflecting both higher realized gold prices and stronger production volumes.

•Owner Mining: AISC averaged 1,482 per ounce, down from 1,537 per ounce in YTD 2024. The improvement reflects higher gold ounces sold. Owner Mining AISC margin increased to $178.0 million, from $48.6 million in the prior year.

•CMPs: AISC increased to 1,865 per ounce, compared to 1,494 per ounce in YTD 2024. The increase was driven by higher gold prices, which elevated mill feed costs. Despite the cost increase, CMPs continue to deliver an AISC margin of 43%, or $91.6 million, up 63% from $56.1 million in YTD 2024.

Non-sustaining growth capital expenditures at Segovia totaled $9.6 million in Q3 2025, compared to $6.9 million in Q2 2025. Expenditures were primarily related to underground mine development and exploration ($5.5 million), completion activities on the Segovia mill expansion following its commissioning in June 2025 ($2.5 million), and ongoing work on the tailings storage facility ($1.2 million) and other plant upgrades.

The Marmato Complex is 100% owned by the Company and is located in a historic mining district of Colombia. It comprises two distinct zones:

•The Narrow Vein Zone is an underground mine currently in operation, supported by a 1,000 tpd processing facility that produces doré.

•The Bulk Mining Zone, located directly below the Narrow Vein Zone, is currently under construction. It will consist of a large-scale underground mine and a dedicated 5,000 tpd CIP processing plant, which will also produce doré.

Gold production was stable at 7,687 ounces, up 8% compared to 7,125 ounces produced in Q2 2025. The slight improvement reflects an increase in tonnes processed and a higher average gold grade which increased to 3.56 g/t in Q3 2025.

Gold production increased 26% year-over-year, supported by a 7% increase in tonnes processed and higher average gold grade (3.56 g/t vs. 3.06 g/t). The increase in throughput is attributable to enhanced operational efficiency and stable mill performance during the period.

Gold production for YTD 2025 reached 22,026 ounces, compared to 17,485 ounces produced in 2024. This is primarily due to higher tonnes processed and an increase in average gold grades.

Gold revenue totaled $24.3 million, a 7% increase from $22.7 million in Q2 2025. The increase was driven by higher gold ounces sold and a 5% improvement in the average realized gold price, which reached $3,280 per ounce in the current quarter.

Gold revenue increased 76% compared to Q3 2024, due to the higher average realized gold price and a 30% increase in gold ounces sold. The higher sales volumes were supported by improved production levels, driven by stable mill performance and higher average gold grades which increased 16% as compared to the prior-year quarter.

For the nine month period, gold revenue reached $65.8 million, up from $39.3 million in 2024, primarily due to a 23% increase in gold ounces sold and a higher average realized gold price of $3,051 per ounce, compared to $2,229 per ounce in 2024.

Revenue increased 27% to $258.1 million, up from $203.5 million in Q2 2025. The increase was primarily driven by a 20% increase in gold ounces sold and a 6% increase in the average realized gold price, which rose to $3,472 per ounce.

Revenue improved 92% from $134.7 million in Q3 2024 to $258.1 million in Q3 2025. The increase was attributable to a 42% improvement in the average realized gold price, up from 2,447 to $3,472 per ounce, combined with a 36% increase in gold ounces sold, reflecting stronger operational performance and ramp up following the successful commissioning of the second mill at Segovia.

Revenue year-to-date 2025 increased 72% to $619.1 million, compared to $359.5 million in 2024. This growth was driven by a 42% increase in the average realized gold price, which rose from $2,272 per ounce in 2024 to $3,228 per ounce in 2025, as well as a 22% increase in gold ounces sold during the period.

Cost of sales increased 21% to $113.7 million, from $94.0 million in Q2 2025. The increase was primarily driven by a 20% increase in gold ounces sold, including a 28% increase in CMP mill feed purchases, reflecting a 17% increase in CMP gold ounces sold and a 6% increase in the average realized gold price. CMP payments are linked to prevailing market prices, which drove mill feed costs higher quarter-over-quarter.

Cost of sales rose 37% from $83.2 million in Q3 2024 to $113.7 million in Q3 2025. The increase mainly reflects a 36% increase in gold ounces sold. CMP mill feed purchases rose 19% due to a 42% increase in the average realized gold price compared to the prior year quarter. Royalties increased by $4.0 million, consistent with the growth in gold revenue.

Cost of sales increased 25% to $290.1 million, from $231.6 million in 2024. Total gold ounces sold rose 22%, from 154,282 in YTD 2024 to 188,306 in YTD 2025, as a result of expanded mill capacity and improved throughput at the Segovia Operations. CMP material costs increased by 13%, reflecting higher gold-linked payments. Royalty payments increased by $8.0 million, consistent with the 72% increase in revenue during the period.

Depreciation and depletion totaled $13.5 million in Q3 2025, up 13% from Q2 2025 primarily due to a 25% increase in production as the expense reflects the units-of-production depletion method applied across operations as well as a higher depletable cost base due to additional sustaining capital investments of $11.9 million during the quarter.

Depreciation and depletion increased 49% from $9.0 million in Q3 2024. The increase reflects a higher depletable cost base, following continued investment in mining interests and infrastructure, as well as higher production volumes, up 37% as compared to Q3 2024.

Depreciation and depletion totaled $36.1 million in 2025, up 47% compared to $24.6 million in 2024. The increase is primarily due to production increases, up 22% across both operations and a higher depletable cost base.

Social contributions totaled $8.2 million in Q3 2025, a 48% increase from Q2 2025. The increase reflects the stepped-rate framework under which contributions are calculated, which links payments to prevailing gold prices and production volumes. The 27% growth in gold revenue, driven by a higher realized gold price and increased ounces sold directly led to the increase in social contributions.

Social contributions increased by $3.7 million compared to Q3 2024, consistent with the year-over-year growth in gold revenue due to higher gold prices and sales volumes.

For the nine month period, social contributions rose 78% to $18.1 million, driven by higher realized gold prices and increased gold sales volumes, consistent with the revenue growth over the same period.

The Company recognized a share based compensation expense of $9.5 million during Q3 2025, up 17% compared to Q2 2025. The increase was primarily driven by the revaluation of the Company's cash-settled performance share units (PSUs), which are fair valued and increased in value in line with the Company's share price.

Share based compensation increased by $7.0 million when compared to Q3 2024 primarily due to the revaluation of the Company's PSUs during the quarter.

During the nine month period ended September 30, 2025, share based compensation totaled $21.4 million as compared to $5.7 million for the same period in 2024. The increase was primarily due to the higher fair value of outstanding PSUs, reflecting the Company's stronger share price performance in 2025, as well as a higher number of units outstanding relative to the prior year.

The major components of the gain (loss) on financial instruments for the current and prior periods are outlined below:

Aris Mining holds financial instruments that are recognized at fair value through profit and loss. In Q3 2025, the Company recognized a $6.4 million loss on financial instruments compared to a $50.7 million loss in Q2 2025. The loss in Q2 2025 was primarily driven by the significant appreciation in the Company's share price which led to a 205% increase in the market price of ARIS.WT.A Listed Warrants, resulting in a $45.5 million loss, recorded on the fair value adjustment to the warrant liability. As of July 30, 2025, there are no further ARIS.WT.A Listed Warrants outstanding. The loss recorded from fair value adjustments on the Warrant liability prior to expiry or exercise was $6.4 million in Q3 2025.

Further, the Company incurred a $7.6 million loss on the Cboe Canada listed Gold Notes (Gold Notes). The valuation of the Gold Notes incorporates credit spreads, risk-free rates, volatility, and gold future prices. The primary driver of the fair-value adjustment in Q3 2025 was a 15% increase in gold prices.

The loss on financial instruments decreased from $12.8 million in Q3 2024 to $6.4 million in Q3 2025 primarily due to a lower loss on the warrant fair value adjustment as well as a $4.6 million gain recorded on the Senior Notes embedded derivative that was entered into in Q4 2024.

The Company recognized a $73.8 million loss on financial instruments in 2025, compared to a $22.7 million loss in 2024. The higher loss was primarily driven by fair value adjustments on the ARIS.WT.A Listed Warrants and Gold Notes, reflecting the impact of changes in the fair value of warrants and gold prices during the period. As of July 30, 2025, there are no further ARIS.WT.A Listed Warrants outstanding. This was partially offset by a fair value gain recorded for the embedded derivative on the 2029 Senior Notes in 2025.

Finance costs in Q3 2025 were broadly consistent with Q2 2025 at $9.4 million. The current quarter reflects a normalized interest expense structure following the refinancing activities in Q4 2024.

Finance costs increased 45% from $6.5 million as compared to Q3 2024. The year-over-year increase reflects the impact of $450 million in debt (2029 Senior Notes) raised in Q4 2024 to refinance the $300 million bond (2026 Senior Notes). The 2029 Senior Notes also carry a higher coupon rate compared to the previous 2026 Senior Notes.

Finance costs for the nine months ended September 30, 2025 increased 53% from $19.8 million in 2024. In line with the increases compared to the prior-year quarter, the year-over-year increase reflects the refinancing of the Senior Notes in Q4 2024.

Aris Mining recorded a foreign exchange loss of $13.5 million in Q3 2025, compared to a loss of $7.2 million in Q2 2025. The $6.3 million quarter-over-quarter difference was due to the appreciation of the COP against the USD during the quarter. This movement resulted in translation losses on USD-denominated monetary assets and liabilities held within subsidiaries whose functional currency is the COP.

The foreign exchange loss of $13.5 million in Q3 2025 compares to a loss of $0.3 million in Q3 2024. This change is primarily attributable to a higher appreciation of the COP during the current quarter as compared to Q3 2024, which reduced the USD value of monetary balances held in COP-functional entities, leading to translation losses.

The Company recorded a foreign exchange loss of $26.7 million in 2025 compared to a gain of $7.0 million in 2024. This change is primarily attributable to the appreciation of the COP during the year as compared to a depreciation in 2024, which reduced the USD value of monetary balances held in COP-functional entities, leading to translation losses.

Income taxes totaled $34.1 million in Q3 2025, a 17% increase from Q2 2025, primarily reflecting higher income from mining operations up 33%, driven by increased gold sales volumes and higher realized gold prices.

Income taxes increased by $18.3 million as compared to Q3 2024, driven by higher income from mining operations due to higher realized gold prices and higher gold ounces sold.

Income taxes increased by 108% to $81.3 million as compared to 2024, driven by higher income from mining operations due to higher realized gold prices and higher gold ounces sold.

The Company continues to maintain a strong liquidity position, and with the combination of operating cash flows from the Segovia Operations and remaining milestone payments from WPMI, there is sufficient cash available to fund operating activities, expansion projects, and strategic initiatives, including the advancement of the Marmato expansion, and study work at Soto Norte and Toroparu.

As at September 30, 2025, the Company held a working capital surplus, defined as current assets minus current liabilities, of $313.8 million (Q4 2024 - $216.3 million), underpinned by a cash balance of $417.9 million. Cash and cash equivalents increased by $165.3 million in 2025. The increase primarily reflects stronger operating cash flow resulting from higher gold sales, proceeds from the exercise of ARIS.WT.A Listed warrants partially offset by continued investment in growth projects. Notably, the Company advanced construction at the Marmato Bulk Mining Zone and made scheduled interest payments on its Senior Notes.

Aris Mining has no off-balance sheet arrangements.

The Company’s related parties include its subsidiaries, affiliates, directors and key management personnel. The Company’s key management personnel includes executive and non-executive directors and the Company’s executive officers.

Other than normal-course intercompany transactions and compensation in the form of salaries or directors’ fees, and share based payments (options, PSUs, DSUs) there were no material related party transactions.

The Company may at times hold financial instruments, derivatives and/or contracts containing embedded derivatives, which are recorded on our consolidated balance sheet at fair value with gains and losses in each period included in other comprehensive income (loss) in the year and profit for the period on our consolidated statements of income and consolidated statements of other comprehensive income, as appropriate. The most significant of these instruments are the Gold Notes.

Aris Mining Holdings Corp. (Aris Holdings), a wholly-owned subsidiary of the Company, has Gold Notes that trade on the Cboe Canada under the symbol “AMNG.NT.U” as described in note 10 of the 2024 annual financial statements. As of September 30, 2025, the outstanding principal value is $31.8 million. The Gold Notes bear interest at 7.5% per annum, payable monthly. In addition to the interest, the Gold Notes pay a gold premium calculated each quarter as the excess of the floor price of $1,400 compared to the London Bullion Market Association Gold Price on the measurement date.

We have not entered into any instruments to hedge against the market movement of gold, and there is risk that rising gold prices would result in higher premiums to be paid. However, there is a natural hedge to this risk as rising gold prices result in higher cash flows from increased AISC margins that are available to fund the potential exposure.

Further information about our financial instruments, derivatives and contracts containing embedded derivatives and associated risks is outlined in Note 16 in our 2024 audited annual consolidated financial statements.

The Company enters into contracts in the normal course of business that give rise to commitments for future payments. The following table summarizes the undiscounted contractual obligations and commitments as at September 30, 2025, which mature over the next five years and beyond:

1.Includes binding commitments for capital and operating purchase obligations that the Company has entered into as at September 30, 2025.

Aris Mining’s gold and silver production from the Marmato Complex and future production from the Toroparu Project, are subject to the terms of streaming agreements with WPMI. In addition, gold and silver production from PSN after the first 5.7 million ounces of gold have been produced is subject to the terms with the precious metals purchase agreement (PMPA) with MDC Industry Holding Company LLC (Mubadala).

In addition, Aris Mining has the obligation to fund Mubadala's 49% share of certain operating costs until the earlier of the receipt of the environmental license for the Soto Norte Project or December 31, 2027.

Associated with the contractual obligations and commitments summarized above, the Company manages its liquidity risk by continuously monitoring forecasted cash flow requirements, as well as any requirements that arise by virtue of the financial instruments held by the Company. The Company believes it has sufficient cash resources to pay its obligations associated with its financial liabilities as at September 30, 2025.

In the ordinary course of business, the Company is involved in and potentially subject to legal actions and proceedings. The Company records provisions in its financial statements for such claims when considered material and an outflow of resources is considered probable.

The Company is subject to tax audits from various tax authorities on an ongoing basis. As a result, from time to time, tax authorities may disagree with the positions and conclusions taken by the Company in its tax filings or legislation could be amended or interpretations of current legislation could change, and any of these events could lead to reassessments. The Company records provisions for such claims when it determines there will be a tax liability associated with its filing position.

As at the date of this MD&A, the Company has 202.7 million common shares issued and outstanding and 5.9 million common shares issuable under stock options. A further 6 million common shares are issuable to Mubadala following receipt of an environmental license to develop PSN.

This MD&A refers to a number of non-GAAP financial measures and non-GAAP ratios, which are not measures recognized under International Financial Reporting Standards (IFRS) and do not have a standardized meaning prescribed by IFRS. The non-GAAP financial measures and non-GAAP ratios described below do not have standardized meanings under IFRS, may differ from those used by other issuers, and may not be comparable to similar financial measures and ratios reported by other issuers. These financial measures and ratios have been derived from our financial statements and applied on a consistent basis as appropriate. The Company discloses these financial measures and ratios because the Company believes that they assist readers in understanding the results of our operations and financial position and provide further information about our financial results to investors. These measures should not be considered in isolation or used as a substitute for other measures of performance prepared in accordance with IFRS.

Total cash costs and total cash costs per ounce sold are a non-GAAP financial measure and a non-GAAP ratio, respectively, and are common financial performance measures in the gold mining industry; however, they have no standard meaning under IFRS. Total cash costs per ounce sold are calculated by dividing total cash costs by volume of gold ounces sold. Aris Mining believes that, in addition to conventional measures prepared in accordance with IFRS such as cost of sales, certain investors use this information to evaluate the Company's performance and ability to generate operating income and cash flow from its mining operations. Management uses this metric as an important tool to monitor operating costs. Management has included a secondary total cash cost and total cash cost per ounce measure, that includes the cost of royalties incurred on precious metal shipments from its Segovia Operations. This measure adds back the cost of royalties to total cash cost and is intended to be reflective of the total cash cost associated with operating in Colombia. Adoption of the World Gold Standard methodology is voluntary and other companies may quantify this measure differently because of different underlying principles and policies applied.

AISC and AISC ($ per oz sold) are a non-GAAP financial measure and a non-GAAP ratio, respectively, and are common financial performance measures in the gold mining industry; however, they have no standard meaning under IFRS. AISC ($ per oz sold) is calculated by dividing AISC by volume of gold ounces sold. The methodology for calculating AISC was developed internally and is calculated below, and readers should be aware that this measure does not have a standardized meaning. This non‐GAAP measure provides investors with transparency to the total period‐attributable AISC of producing an ounce of gold and may aid in the comparison with other gold mining peers. Management uses this metric as an important tool to monitor operating costs. Accordingly, it is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS.

Adjusted net earnings and adjusted net earnings per share (basic) are a non-GAAP financial measure and non-GAAP ratios, respectively, and are common financial performance measures in the gold mining industry; however, they have no standard meaning under IFRS. Adjusted net earnings per share (basic) are calculated by dividing adjusted net earnings by the number of shares outstanding on a basic basis.

Adjusted net earnings and adjusted net earnings per share (basic) are used by management and investors to measure the underlying operating performance of the Company. Presenting these measures from period to period helps management and investors evaluate earnings trends more readily in comparison with results from prior periods.

Adjusted net earnings is defined as net income adjusted to exclude specific items that are significant but not reflective of the underlying operating performance of the Company, such as: share-based payments, change in fair value of financial instruments, foreign exchange gains and losses, income and losses from equity accounting in investees, and other non-recurring items. Adjusted net earnings per share amounts are calculated using the weighted average number of shares outstanding on a basic basis as determined under IFRS. In the table below the Company has provided the reconciliation of adjusted net earnings to the most directly comparable financial measure disclosed in the Financial Statements.

EBITDA and Adjusted EBITDA are Non-GAAP financial measures and are common financial performance measures in the gold mining industry; however, they have no standard meaning under IFRS. EBITDA represents earnings before interest (including non-cash accretion of financial obligations and lease obligations), income taxes and depreciation, depletion and amortization.

EBITDA is then adjusted to exclude specific items that are significant but not reflective of the underlying operating performance of the Company, such as: share-based payments, change in fair value of financial instruments, foreign exchange gains and losses, income and losses from equity accounting in investees, and other non-recurring items (Adjusted EBITDA). In the table below the Company has provided the reconciliation of EBITDA and adjusted EBITDA to the most directly comparable financial measure disclosed in the Annual Financial Statements.

The Company’s unaudited condensed consolidated interim financial statements have been prepared in accordance with IAS 34, Interim Financial Reporting, using accounting policies consistent with those applied in the Company’s audited consolidated financial statements for the years ended December 31, 2024 and 2023. Details of the significant accounting policies are disclosed in note 3 of the Company’s audited consolidated financial statements.

Exploration, development and mining of precious metals involves numerous inherent risks. As such, Aris Mining is subject to financial, operational and political risks that could have a significant impact on its profitability and levels of operating cash flows. Although Aris Mining assesses and minimizes these risks by applying high operating standards, including careful management and planning of its facilities, hiring qualified personnel and developing their skills through training and development programs, these risks cannot be eliminated. Readers should consider the information included or incorporated by reference in this document and the Interim Financial Statements and related notes thereto. Additionally, readers are encouraged to read and consider the risk factors which are more specifically described under the caption "Risk Factors" in the Company's AIF for the year ended December 31, 2024 dated as of March 12, 2025, which is available on www.aris-mining.com, under the Company's profile on SEDAR+ at www.sedarplus.ca and included as part of the Company's Annual Report on Form 40-F, filed with the SEC at www.sec.gov.

If any of these risks materialize into actual events or circumstances or other possible additional risks and uncertainties of which the Company is currently aware or which it considers to be material in relation to the Company's business actually occur, the Company's assets, liabilities, financial condition, results of operations (including future results of operations), business and business prospects, are likely to be adversely affected. In such circumstances, prices of the Company's securities could decline, and investors could lose all or part of their investment. In addition, such risk factors could cause actual amounts to differ from those described in the forward-looking statements related to the Company.

Disclosure controls and procedures have been designed to provide reasonable assurance that all material information required to be disclosed by the Company is accumulated and communicated to senior management as appropriate, and recorded, processed, summarized, and reported to allow timely decisions regarding required disclosure, including in its annual filings, interim filings, or other reports filed or submitted under securities legislation.

The Company's management, including the Chief Executive Officer and Chief Financial Officer, is responsible for establishing adequate internal controls over financial reporting.

During the three months ended September 30, 2025, there were no changes in the Company's internal controls over financial reporting that materially affected or are reasonably likely to materially affect the Company's internal controls over financial reporting.

The Company's management, including the Chief Executive Officer and Chief Financial Officer, believe that any disclosure controls and procedures or internal controls over financial reporting, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, they cannot provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been prevented or detected. These inherent limitations include the realities that judgments in decision-making can be faulty and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by unauthorized override of the control.

The design of any systems of controls is also based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Accordingly, because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.
