VANCOUVER, British Columbia--(BUSINESS WIRE)--July 29, 2026--Aris Mining

Corporation (Aris Mining or the Company) (TSX: ARIS; NYSE: ARIS) announces its financial

and operating results for the three and six months ended June 30, 2026 (Q2 2026 & H1 2026).

All amounts are in U.S. dollars unless otherwise indicated.

Q2 2026 Financial Performance

 Production of 73.7 thousand ounces (koz) of gold, consistent with Q1 2026.

 Gold revenue of $321 million, with an average realized gold price of $4,450.

 Adjusted EBITDA1 of $179 million, on a trailing 12-month basis, Adjusted EBITDA of

$690 million.

 Adjusted net earnings of $96 million or $0.47/share, on a trailing 12-month basis,

Adjusted net earnings of $386 million or $1.89/share.

 Cash balance of $426 million as of June 30, 2026, after funding $121 million in capital

projects in Q2 2026, including $78 million at Marmato and $31 million at Segovia.

Neil Woodyer, Chair and CEO, commented “Aris Mining delivered another strong quarter with

our operations generating the cash required to fund more than $120 million of capital

investments during the second quarter while maintaining a strong balance sheet.

At Marmato, underground access connecting the Bulk Mining Zone to the new plant area is

complete, the SAG and ball mills are on site, and mechanical installation is underway.

Construction of the 5,000 tpd CIP plant continues to advance toward first gold and is on schedule

for Q4 2026. At Segovia, increased investment in underground development and haulage

infrastructure is building the mining capacity required to support higher production from the

expanded processing facilities.

We remain on track to achieve our 2026 production guidance. With Segovia and Marmato

providing a clear path toward approximately 500,0002 ounces of annual production, and Soto

Norte and Toroparu continuing to advance, Aris Mining is well positioned to deliver its longer-

term growth strategy.

At Soto Norte, the environmental studies and preparation of the environmental license

application are nearing completion. At Toroparu, the prefeasibility study remains on schedule for

completion in the second half of 2026.”

Q2 & H1 2026 Operational Performance

 Segovia produced 64.4 koz, bringing H1 2026 production to 131.0 koz.

o Q2 2026 production reflected higher throughput, with 202.5 thousand tonnes (kt)

processed at an average gold grade of 10.23 g/t, compared with 175.4 kt at 12.41

g/t in Q1 2026.

o Segovia’s Q2 results reflect continued investment in underground development to

support the ramp-up toward consistent utilization of the expanded 3,000 tonnes

per day (tpd) processing capacity installed in June 2025. Tonnes processed

increased by 15% quarter-over-quarter to 202.5 kt, while total Segovia

investment, including sustaining and non-sustaining capital, increased to $31

million in Q2 2026 from $17 million in Q1 2026.

o This investment of $48 million in H1 2026 is advancing the development work

required to increase mining rates and improve haulage efficiency, including new

ramps and a main underground haulage circuit connecting the El Silencio,

Providencia and Sandra K mines. This work is being supported with the order of

an expanded mining fleet through a combination of purchase and leasing

arrangements to renew aging equipment and advance the expansion plan. Once

complete, these initiatives are expected to support increased mill feed, more

efficient transport of workers, mill feed and waste, shorter cycle times, and

reduced traffic through town.

o Segovia generated an AISC margin of $157 million in Q2 2026, supported by

higher tonnes processed and continued strong gold prices, bringing H1 2026

AISC margin to $356 million.

o Owner-operated mining contributed 67% of mill feed, while Contract Mining

Partner (CMP) sourced material contributed 33%, consistent with Q1 2026.

o Owner-operated mining AISC was $1,767/oz for Q2 2026, bringing H1 2026

owner-operated mining AISC to $1,623/oz, below the full-year 2026 guidance

range of $1,700 to $1,800/oz. The increase from Q1 2026 partly reflected higher

sustaining capital as the Company increased investment in underground

development to support higher mining capacity.

o CMP-sourced gold delivered an AISC sales margin of 46% in Q2 2026, bringing

H1 2026 CMP AISC sales margin to 43%, above the top-end of the full-year 2026

guidance range of 35% to 40%.

o Combined AISC is $1,974/oz for H1 2026.

 Marmato produced 9.3 koz, bringing H1 2026 production to 17.1 koz.

o Q2 2026 production reflected the processing of 84.6 kt at an average gold grade

of 3.79 g/t, compared to 77.0 kt at 3.53 g/t in Q1 2026.

o 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 and CMPs operating in the Narrow Vein Zone.

o Throughput is expected to increase materially following commissioning of the

new 5,000 tpd carbon-in-pulp (CIP) plant, with first gold expected in Q4 2026.

o Aris Mining plans to exit 2026 operating the new CIP plant at approximately

3,000 tpd, before ramping up through 2027 to approximately 4,000 tpd by mid-

2027 and the full 5,000 tpd design capacity by the end of 2027, following

commissioning of the paste backfill plant.

 2026 Outlook

o Aris Mining remains on track to achieve its 2026 production guidance of 300,000

to 350,000 ounces of gold.

o H1 2026 production of 148 koz represents approximately 49% of the low end and

46% of the midpoint of the full-year guidance range, with production expected to

be weighted to the second half of the year.

o Segovia is expected to continue increasing mining capacity and production

through the second half of the year.

o Marmato's new 5,000 tpd design-capacity CIP plant remains on schedule for first

gold in Q4 2026, supporting the Company's 2026 production guidance for

Marmato of 35,000 to 50,000 ounces.

o The lower end of the Marmato guidance range is expected to be achievable

through the existing flotation plant, while the upper end assumes successful

commissioning of the new CIP plant in Q4 2026.

Project Development Highlights

 Marmato expansion advancing toward commissioning and first gold

o Construction of the new 5,000 tpd design-capacity CIP plant remains on schedule

for first gold in Q4 2026.

o The SAG and ball mills are on site and mechanical installation is underway.

o The Bulk Mining Zone is prepared to support the initial ramp-up of the new CIP

plant. The underground connection completed earlier this year established direct

access between the Bulk Mining Zone and the new process plant area, improving

access, ventilation and haulage, and supporting the planned production ramp-up.

o As at July 1, 2026, the estimated capital required to achieve first gold from the

Marmato CIP plant in Q4 2026 is approximately $118 million. After the final $42

million installment expected from Wheaton Precious Metals in Q3 2026, the net

funding requirement of approximately $76 million will be funded from the

Company’s cash balance and operating cash flow.

 Toroparu Project progressing toward a potential early 2027 construction decision

o The Prefeasibility Study (PFS) remains on schedule for completion in H2 2026,

supporting a construction decision targeted for early 2027.

o Project optimization work in support of the PFS includes updated mine

scheduling, engineering studies and other activities to advance to construction

readiness.

o Pre-construction activities underway, including construction of the Puruni River

bridge, camp expansion, road improvements and other site infrastructure.

o The project team has grown to 100 employees in Guyana, with several key

leadership appointments made during the quarter to support project development

and execution.

o Aris Mining continues active engagement with the Government of Guyana and

the Guyana Geology and Mines Commission (GGMC) to obtain the mining

license and keep stakeholders informed of project progress.

o Preliminary Economic Assessment (PEA) completed in October 2025, outlining

an attractive project with average annual gold production of 235 koz and an after-

tax NPV5% 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 nearing completion of environmental studies and environmental

license application preparation

o The project incorporates industry-leading environmental and social design

features, including a metallurgical process free of cyanide and mercury, together

with a CMP program that allocates approximately 750 tpd of processing capacity

to local miners, over 20% of Soto Norte’s 3,500 tpd processing capacity.

o The environmental studies and preparation of the environmental license

application are nearing completion.

o PFS completed in September 2025, demonstrating robust economics with average

annual gold production (years 2 to 10) of 263 koz and an after-tax NPV5% 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 NPV5%

increases to $3.3 billion with an IRR of 40%.

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 Toronto

Stock Exchange and the New York Stock Exchange 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 ounces2, 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 production7. Key projects include the high-grade Soto Norte gold project in

Colombia and the Toroparu gold project in Guyana, where a Prefeasibility Study is in progress

and a construction decision is expected in early 2027.

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. 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.
