TSX-V: ARK / OTCQB: ARRKF

VANCOUVER, BC

Oct. 8, 2025

/CNW/ -

Arras Minerals Corp.

(TSXV: ARK) (OTCQB: ARRKF)

("Arras" or "Arras Minerals" or "the Company")

is pleased to announce drill results from the

Berezski East Target at the Elemes Project. Hole EL25019 delivered wide zones of high-grade gold-

copper mineralization starting at surface. This hole underscores the scale potential that is developing

in the Berezski Central – Berezski East area of the Elemes Project.

Highlights include:

EL25019:

457.50m

of mineralization grading 0.63 g/t gold-equivalent

("AuEq") (0.61 g/t Au

and 0.10% Cu), starting at surface; including:

231.0m

grading 0.98 g/t AuEq (0.97 g/t Au, 0.13% Cu) starting from surface

91m

grading 1.77 g/t AuEq (1.79 g/t Au, 0.19% Cu) starting at

88m

depth

EL25017:

37.0m

of mineralization grading 0.13 g/t gold-equivalent

("AuEq") (0.11 g/t Au

and 0.02% Cu)

9.5m of mineralization grading 0.55 g/t AuEq (0.48 g/t Au, 0.08% Cu)

Tim Barry

, CEO of Arras Minerals, commented:

" Drillhole EL25019 has delivered an

exceptional high-grade gold-copper intercept from surface, confirming Berezski East's strong

potential to host broad zones of high-grade mineralization. Broad zones of potassic alteration and

the presence of copper minerals such as bornite and chalcopyrite suggests this target may form

part of a larger porphyry system — a highly encouraging development. When we look at the area

between Berezski Central and Berezski East, we continue to see the potential for continuity and

scale. Additional holes are being planned at Berezski East, and we already have a focus at

Berezski Central with one dedicated drill rig currently operating there."

Hole EL25017

was designed to follow-up on mineralization intersected in hole EL25013 (

192m

grading 0.18 g/t AuEq), that targets a prominent copper-in-soil anomaly located 1.7 kilometers north

of the Berezski Central target. The hole was collared in fine to medium grained andesite breccias. At

105.7m

depth, the hole passed into andesites to the end of the drill-hole at

250.5m

depth. Alteration

is dominated by argillic overprinting earlier propylitic and phyllic alteration. Mineralization is

characterized by disseminated pyrite (0.5–3%, locally up to 5%), with minor zones of pyrite D-type

veins.

The character and intensity of the mineralization intersected in hole EL25013 and EL25017 appear

to represent the distal part of a porphyry Cu-Au system. Company geologists are reviewing the data

collected in this area to determine if mineralization is related to the Berezski Central system located

1.7km to the south.

Hole EL25019

was drilled approximately

250m

north from EL24004 (

86.8m

grading 0.97 g/t AuEq)

on the Berezski East Target. The hole intersected

457.7m

of fine-grained grey-greenish-grey

diorites. Alteration was dominated by potassic alteration with alternating intensity of K-feldspar and

biotite down the hole.

Mineralization consists of disseminated and patchy pyrite with minor zones of bornite and

chalcopyrite mineralization. Several intense zones of hematite-magnetite and k-feldspar-quartz veins

were intersected with associated pyrite, chalcopyrite and bornite.

Earlier this year, drill results from Berezski East confirmed broad zones of gold mineralization,

thought to be related to a robust epithermal gold system. The discovery of copper sulfides

(chalcopyrite and bornite) and broad zones of potassic alteration in hole EL25019 has highlighted a

new style of mineralization, indicating that Berezski East may be situated on the margin of a larger

porphyry Cu-Au system. To further advance this target, the company has undertaken detailed MT

and gravity surveys and will commence a high-density top-of-bedrock drill program in the coming

weeks. Preliminary results from the gravity survey have been partially received and the results from

the MT survey are expected in November. This program is designed to provide critical information on

the geometry and scale of the system and to guide the next phase of exploration of this target.

Exploration Update

At the

Novii target

, which is located 4.4 km southwest of Berezski Central, Arras has completed

three drill-holes totalling

1000m

, focusing on a 2.5 x 1.5-kilometre area defined by strong arsenic-in-

soil anomalies and hematite-filled fractures (see Figure 5). The program intersected layers of

volcanic and limestone rocks. Notably, hole NOV25001 encountered zones of massive sulphide

mineralization within faults and fractures, while hole NOV25003, targeting the southern continuation

of the magnetic low associated with mineralization at Berezski Central, intersected brecciated

andesites and diorites beneath the volcanic cover containing porphyry-style mineralization, including

B-type quartz-molybdenite veins and finely disseminated chalcopyrite. Assays are pending and

expected next month.

Due to the discovery of porphyry-style mineralization in hole NOV25003, the gravity and MT surveys

have been expanded by an additional 102 stations to cover this new target area (Novii). The field

work for this survey will continue to the end of October.

The company has also received preliminary results from the gravity survey conducted over the

Berezski Central and Berezski East targets, and the findings are highly encouraging. The data (see

Figure 2) reveals a pronounced gravity low coincident with the copper-gold mineralization at Berezski

Central. A second gravity low has been identified immediately northeast of hole EL25019, supporting

the company's interpretation that the copper-gold mineralization and potassic alteration intersected

indicates that this hole cold be proximal to the core of a mineralized porphyry system, in contrast to

the lower-temperature, gold-only mineralization encountered in hole EL24004.

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, sixteen holes totaling more than

6,000m

, have been drilled. 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.

"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.
