VANCOUVER, BC

Nov. 4, 2025

/CNW/ -

Arras Minerals Corp.

(TSXV: ARK) (OTCQB: ARRKF)

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

is pleased to announce additional drill results

from the Berezski Central target at the Elemes Project. Drill holes EL25018 and EL25020 continue

to intersect broad zones of copper and gold mineralization and have expanded the footprint of the

Berezski Central zone to approximately

600m

500m

and open in all directions. Hole EL25018 has

also revealed a potentially new zone of gold mineralization along the western margin of the Berezski

Central zone. This new zone represents an exciting potential exploration target for future drilling and

further highlights the growth potential of the Elemes Project.

Highlights include:

EL25018:

192.0 of mineralization grading 0.36% copper-equivalent ("CuEq")

(0.19 g/t Au

and 0.13% Cu), starting at

52.0m

depth; including:

104.0 of mineralization grading 0.49% CuEq

(0.25 g/t Au and 0.16% Cu), starting at

52.0m

76.0m

grading 0.53 % CuEq (0.28 g/t Au, 0.17% Cu) starting at

76.0m

depth

48.0m

grading 0.60% CuEq (0.32 g/t Au, 0.18% Cu) starting at

104.0m

depth

9.4m

grading 0.51 g/t Au starting at

564.6m

depth

EL25020:

(0.14 g/t Au and 0.12% Cu),

starting at

358.1m

depth; including:

129.0m

of mineralization grading 0.35 % CuEq (0.16 g/t Au, 0.16% Cu) starting from

475.0m

depth

55.9m

of mineralization grading 0.38% CuEq (0.21 g/t Au, 0.13% Cu) starting from

358.1m

depth

Tim Barry

, CEO of Arras Minerals, commented:

"Our confidence in the Berezski Central target

continues to strengthen with each round of drilling. We are steadily expanding beyond the known

zones of mineralization, and results to date have outlined broad, near-surface intervals of copper-

gold mineralization over an area now measuring roughly 600 metres by 500 metres. Our goal is to

focus on continuing to grow this footprint and unlocking the full potential of the Berezski Trend.

Encouragingly, in drill-hole EL25018, in addition to defining wide zones of copper-gold

mineralization from shallow depths and extending the mineralization more than 200 metres north,

we've also identified a potential new zone of gold mineralization at depth, which could represent an

additional system altogether.

Drill hole EL25020, located 100 metres northwest of hole EL24001 intersected multiple zones of

mineralization throughout its length, including a broad 314-metre interval grading 0.30% CuEq.

These results, combined with the presence of several porphyritic intrusions, continue to point to a

robust and dynamic mineral system at Berezski Central.

We've also just completed a top-of-bedrock drill program across the Berezski Central and Berezski

East targets, we'll soon have valuable new data to assess how these areas are related, and to

evaluate the potential for a much larger, district-scale porphyry system at the heart of the Berezski

Trend."

Hole EL25018:

Located

300m

northwest of hole EL24001 and designed to explore the northern

continuation of the Berezski Central zone. The hole was collared in fine-medium grained andesites,

before passing into medium grained diorites. Within this diorite unit, a series of porphyritic feldspar

andesite dykes have been emplaced. The hole was extended to

608m

depth to fully explore these

units to learn more about their extents and orientation. It was noted that the diorites contained

numerous xenoliths of monzonites that suggest that this hole has intersected a more dynamic part of

the porphyry system showing multiple intrusive phases and that the diorites and andesites are the

host, not the source of the porphyry style mineralization at Berezski Central.

Alteration was dominated by moderate phyllic, overprinted by weak argillic, and zones of minor

propylitic alteration. Mineralization mostly occurred as pyrite in veins, dissemination and in patches.

Minor quartz veining was observed, as well as chalcopyrite patches, with minor molybdenite on

fractures in fault zones. At

565m

depth, the hole hit a highly silicified zone, with up to 10% pyrite and

minor chalcopyrite, that returned high-gold values. The company thinks that this could be the root of

a gold-dominant system and will endeavor to explore this area with follow-up drilling once the results

from the KGK drilling have been received.

Hole EL25020

: This hole is located

100m

to the northeast of hole EL24001. The hole was collared

in highly altered diorites, with intense argillic alteration at the top of the hole, transitioning into

propylitic and phyllic altered diorites with local argillic overprinting along fault and fracture zones. The

hole intersected several post-mineral andesite dykes with weak magnetite, chlorite alteration. The

hole was terminated at

771.5m

depth, where the hole intersected the porphyritic feldspar andesites

that had been intersected in hole EL25018, further helping the company define this unit. At the top of

the hole alteration is dominated by moderate phyllic alteration. At depth we see alternating zones of

strong silicification, phyllic, and propylitic assemblages.

Mineralization consists of disseminated Pyrite, ranging from 1-3% locally, with zones of disseminated

Chalcopyrite, Molybdenite, Sphalerite and Galena are also observed in fractures and in veins. At

depth, in the diorites, we see chalcopyrite and molybdenite on around fractures and in halos around

veins. We also see several narrow zones of C-type pyrite-chalcopyrite veins were observed, that

are typically located in the intermediate to upper part of a porphyry system, normally peripheral to

the high-grade core. The company believes that mineralization has been offset by a previously

unrecognized east-west striking fault that appears to have shifted the copper-gold mineralization to

the west.

Exploration Update

Magnetotellurics ("MT") and gravity surveys have been successfully completed at the Elemes

project. An additional 102 stations were added to extend coverage over the 2.5 x 1.5-kilometre

arsenic-in-soil geochemical anomaly that defines the Novii target. Final survey data is expected to be

delivered this month. The company has engaged a third-party contractor in

the United States

, to

process and interpret the results. The MT and gravity data are expected to provide critical vectors

toward the core of the porphyry systems identified at Elemes (Berezski and Aimandai trends), while

also enhancing the company's ability to define additional porphyry targets believed to lie beneath

post-mineral cover.

Elemes top of bedrock drill program:

the preliminary data from the gravity survey suggested that

the Berezski Central and East deposits may be part of much larger system. However, the minimal

outcrop exposure in the area has made geological mapping challenging, and in October, a 64-holes,

totaling 1,663-metres, base of till/top-of-bedrock drilling program was completed over these targets.

The program was designed to rapidly evaluate geology and mineralization beneath shallow cover

(typically 10-

20m

, but up to

50m

at Berezski East) over this area. Initial observations have identified

multiple intrusive rocks, extensive argillic alteration and disseminated pyrite and potentially zones of

supergene copper mineralization, all of which are encouraging indicators of porphyry mineralization

and may suggest a connection between the Berezski Central and Berezski East systems. All

samples have been submitted to ALS Chemex for analysis, with results expected from late

November to early December.

Elemes Phase II Drill Program:

Since June, Arras Minerals has been advancing its 20,000-metre

Phase II diamond drill program at the Elemes project. Two drill rigs are currently testing the highly

prospective Berezski Trend, following up on the strong results from the 2024 campaign. To date,

approximately 8,000 metres have been completed. In parallel, the Company has finalized

Magnetotellurics ("MT") and gravity surveys across key sections of the Berezski and Aimandai

Trends to refine and guide future targeting and completed a 64-hole, 1,663-metre top-of-bedrock

drilling program. Diamond drilling is expected to continue through the remainder of 2025 and into

2026, with results anticipated to drive the next phase of exploration and discovery.

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 copper-gold mine (~60 km northwest), which reported mined grades in Q1 2025

of 0.37% Copper and 0.20 g/t gold.

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.
