VANCOUVER, BC

Sept. 8, 2025

/CNW/ -

Arras Minerals Corp.

(TSXV: ARK) (OTCQB: ARRKF)

("Arras" or

"Arras Minerals" or "the Company")

is pleased to announce the assay results from drillhole EL25016, from

the ongoing drilling on the Elemes Project in

Northeast Kazakhstan

. The program is designed to systematically

test multiple high-priority targets along the 8.8-kilometre Berezski and the 14-kilometre Aimandai Trends.

Highlights include:

EL25016:

276m

of mineralization grading 0.58 % copper-equivalent

("CuEq") (0.21% Cu and 0.32 g/t

Au), starting at surface; including:

104m

grading 1.14% CuEq (0.46 % Cu, 0.63 g/t Au) starting from surface

52m

grading 1.64% CuEq (0.72 % Cu and 0.86 g/t Au) starting at

48m

depth

Tim Barry

, CEO of Arras Minerals, commented:

"The results from Hole EL25016 located approximately 300

metres southeast of Hole EL24005 intersected thick zones of high-grade copper-gold mineralization from

surface. Interestingly, this hole shows very good grades and widths right from surface outside of the breccia

zone that carried much of the higher-grade intercepts in the earlier two holes, EL 24005 and EL25014A. This

is a positive outcome for this most recent drill hole and for future follow-up targeting."

He went on to add,

While we still need to further trace the origin of the high-grade breccia zone at Berezski North, we have now

defined a 600 metre NW-SE trending zone at Berezski North that remains open in the northwest and southeast

directions and at depth.

Hole EL25016:

Drillhole EL25016 was drilled approximately

300m

to the southeast of drill-hole EL24005 and

was designed to test the extent of the hydrothermal breccias and associated mineralization. The hole was

collared in highly weathered andesites from surface to

29m

depth. From 29 metres to 124.5 metres, the

andesites were intensely altered, fractured, and showing strong argillic alteration overprinting an earlier phyllic

phase characterised by sericite-altered D-type veins. At 124.5 metres, the lithology changes into diorites

containing xenoliths of monzonites, gabbros, and andesites. Alteration in this zone changes to strong inner

propylitic with a weak argillic overprint along fractures.

Mineralization is most intense in the upper part of the drill hole. From 30 to 90 metres, mineralization consists of

patches and disseminations of pyrite, chalcopyrite, and enargite, and at 123.4 metres, the hole intersected a

fault zone where mineralization changed, becomes weaker and consisting predominantly of disseminated pyrite

and chalcopyrite with occasional quartz-sulphide veins.

Overall, the drill hole continues to show that the is a vertically zoned hydrothermal system at Berezski North. In

the upper part of the drill-hole, argillic-altered volcanics host high-grade copper mineralization dominated by

chalcopyrite with enargite, while the deeper part of the hole are dominated by disseminated pyrite and

chalcopyrite, and may represent a different part of a porphyry system that was intersected by drill-hole

EL24005.

Elemes Phase II Drill Program:

Since late June, Arras has been advancing its 20,000-metre Phase II diamond

drill program at Elemes. Two rigs are actively testing the highly prospective Berezski Trend, building on the

success of the 2024 campaign. To date, nine holes have been completed, with assays pending for several. In

parallel, the Company is carrying out Magnetotellurics ("MT") and gravity surveys across key sections of the

Berezski and Aimandai Trends, which will guide and refine future targeting. Drilling is scheduled to continue

through to the end of the year and continue into 2026.

Elemes Project Overview:

The Elemes Project comprises two exploration licenses covering 531 square

kilometres in northeast

Kazakhstan

, located approximately 13 km southwest of Ekibastuz and just 20 km from

Arras's operational base. The project benefits from exceptional infrastructure, with a paved highway crossing

the licence, and access to 1100 KVA power lines, heavy rail, and other utilities within a 15 km radius.

Situated within the prolific Bozshakol-Chingiz metallogenic belt, Elemes lies near significant regional deposits,

including the Beskauga porphyry copper-gold-silver deposit (~80 km east) and KAZ Minerals' Bozshakol mine

(~60 km northwest)

Geologically, the property is underlain by interbedded intermediate volcanic and sedimentary rocks intruded by

multiple phases of diorite and monzodiorite porphyry. Copper-gold mineralization occurs in sheeted and

stockwork quartz-chalcopyrite veins associated with these intrusions. In addition, high-grade low-sulphidation

epithermal veins have been mapped on the property, representing a secondary exploration target.

Property-wide soil sampling programs in 2022 and 2023 defined two extensive Cu-Mo-As geochemical

anomalies: the Berezski and Aimandai Trends, both considered priority targets for follow-up exploration drilling.

Initial drilling on the Berezski Trend in late 2024 returned high-grade porphyry/epithermal copper and gold

mineralization.

About Arras Minerals Corp:

Arras is a Canadian exploration and development company advancing a portfolio

of copper and gold assets in northeastern

Kazakhstan

, including the Elemes copper-gold porphyry project. The

Company has established one of the largest land packages in the country prospective for copper and gold. In

December 2023

, the Company entered into a strategic alliance with Teck Resources Limited ("Teck") in which

Teck may sole fund a

US$5 million

generative exploration program over a portion of the Arras license package

in 2024-2025. The Company's shares are listed on the TSX-V under the trading symbol "ARK" and on the

OTCQB under the trading symbol "ARRKF".

Technical Disclaimer

The Company is aware of historical drilling on the Elemes property, with approximately 30 holes reportedly

completed by a previous operator in 2007–2008. Efforts to validate this information have been unsuccessful, as

the available data is incomplete and lacks critical details on drill hole locations, downhole surveys, assays, and

geological records.

Field inspections revealed significant discrepancies, often tens to hundreds of meters between reported

coordinates and the physical locations of unidentified drill collars observed on site.

Given these limitations, the Company has determined that the historical data cannot be relied upon for resource

estimation or technical interpretation. Nonetheless, the results suggest that past drilling encountered copper and

gold mineralization related with a porphyry–epithermal system.

The Company has not disclosed mineral resources in respect of any of its projects. All disclosure regarding the

Company's projects including, without limitation, the Bozshakol copper project owned/operated by Kaz Minerals

plc and the Nurkagan project owned/operated by Kazakhmys has been derived from third party sources which

the Company's management believes to be reliable in light of the circumstances. Readers are cautioned that the

Company has no interest in any of such projects, has not independently verified any data or information with

respect to such projects, and such information may be prepared and presented on the basis of different

standards than that set out in National Instrument 43-101 – Standards of Disclosure for Mineral Project ("NI 43-

101") or standards to which the reader may be accustomed.

There is no guarantee that the information presented with respect to such projects will be comparable to values

calculated in accordance with NI 43-101. Information contained herein with respect to any other projects is not

indicative or representative of the results that may be obtained by the Company in respect of its projects.

Readers are expressly cautioned not to assume any correlation between information presented herein with

respect to such other projects and the Company's projects. We assume no responsibility for any information

contained herein in respect of any such other projects.

Cautionary Note to U.S. Investors concerning estimates of Measured, Indicated, and Inferred

Resources:

References contained in this press release uses the terms "measured resources", "indicated

resources", and "inferred resources" which are defined in, and required to be disclosed by, NI43-101. The

Company advises U.S. investors that these terms are not recognized by the SEC. The estimation of measured,

indicated and inferred resources involves greater uncertainty as to their existence and economic feasibility than

the estimation of proven and probable reserves. U.S. investors are cautioned not to assume that measured and

indicated mineral resources will be converted into reserves. The estimation of inferred resources involves far

greater uncertainty as to their existence and economic viability than the estimation of other categories of

resources. U.S. investors are cautioned not to assume that estimates of inferred mineral resources exist, are

economically minable, or will be upgraded into measured or indicated mineral resources. Under Canadian

securities laws, estimates of inferred mineral resources may not form the basis of feasibility or other economic

studies. Disclosure of "contained ounces" in a resource is permitted disclosure under Canadian regulations,

however the SEC normally only permits issuers to report mineralization that does not constitute "reserves" by

SEC standards as in place tonnage and grade without reference to unit measures. Accordingly, the information

contained in this press release may not be comparable to similar information made public by U.S. companies

that are not subject NI 43-101.
