TSX-V: ARK / OTCQB: ARRKF

VANCOUVER, BC , March 2, 2026 /CNW/ -Arras Minerals Corp.(TSXV: ARK) (OTCQB: ARRKF) ("Arras" or "Arras Minerals" or "the Company") is pleased to report the final drill results from the 2025 drilling at the Elemes Project in northeastern Kazakhstan.

Highlights include:

• EL25027: 52.4m of mineralization grading 2.11% copper-equivalent ("CuEq") (1.49 g/t Au, 0.58% Cu) starting from 167.6m at Berezski North which was from within a broader zone of 446.0m grading 0.45% CuEq (0.31 g/t Au and 0.13% Cu), starting at 160.0m depth
  
  
• EL25028: 135.0m of mineralization grading 0.43% copper-equivalent (0.21 g/t Au and 0.19% Cu) at Berezski Central, starting at 6.0m depth, including 95.0m grading 0.50% CuEq (0.24 g/t Au and 0.22% Cu) starting from 6.0m depth

Berezski North
Hole EL25027 intersected broad intervals of Cu-Au mineralization starting from 160m below surface, including a high-grade interval returning 52.4m grading 2.11% CuEq from 167.6m. The hole targeted the southern continuation of the porphyry mineralization encountered towards the bottom of hole EL24005. The hole intersected the tourmaline breccia zone at approximately 160m down hole and this zone now stretches over a 500m strike length. The hole continued and intersected porphyry-style mineralization and alteration, consisting of zones of sheeted veining with chalcopyrite and bornite mineralization associated with widespread potassic alteration at approximately 460m depth. This suggests that the hole has intersected the edge of the high-temperature core of a porphyry system.

These results further enhance the Company's confidence in the scale and continued discovery potential of Berezski North. Mineralization remains open in multiple directions, and the results from this hole are consistent with our current thesis that vectoring to the south and west appears to be getting more proximal to the potential centre of the system.

Berezski Central
Hole EL25028 was drilled approximately 350m northwest of drill hole EL24001 (261m grading 0.39 g/t Au and 0.24% Cu) and intersected broad intervals of Cu-Au mineralization hosted within mineralized and altered diorites. This hole extends mineralization a further 200m to the northwest with the hole being terminated in mineralized diorites at a depth of 575.8m. The Berezski Central targets now measures approximately 750m x 500m based on drilling to date and remains open to the north, south and at depth.

Tim Barry, CEO of Arras Minerals commented,  "The final set of results from the drilling completed in December continue to further expand the footprints of both the Berezski North and Berezski Central targets. At Berezski North, Hole EL25027 intersected high-grade copper–gold mineralization associated with the known tourmaline breccia zone but also a new zone containing sheeted veining, chalcopyrite–bornite assemblages and strong potassic alteration reinforcing our interpretation that we are vectoring toward the high-temperature core of a robust porphyry system, likely to the south and west. At Berezski Central, Hole EL25028 expanded the known area of mineralization a further 200m to the northwest with broad intervals of copper–gold mineralization in altered diorites. Both porphyry centres remain open in most directions and our Phase 2 drill program is ramping up to four drills turning on these targets by mid-March."

Drill Highlights:

• Hole EL25024 was drilled at the Berezski Central target. Aiming to test the northern continuation of the Cu-Au intercepts seen in the holes EL24001 and EL24002. Unfortunately, the hole was lost at 80.2m depth due to geological complications and issues with drilling equipment, before reaching the deeper sulphide mineralization. The hole intersected strongly altered, weathered and fractured diorites, with pervasive disseminated chalcopyrite with minor chalcopyrite, sphalerite and zones of secondary copper sulphides and quartz-pyrite veining.
• Hole EL25025 was drilled at Berezski Central and was collared 100m north of holes EL25024 and EL25026, to test the northern continuation Cu-Au mineralization. The hole drilled strongly weathered diorites from surface to 32.2m depth before passing into a unit of diorite breccias to the end of the drill-hole at 80.1m depth, where the hole intersected strong faulting and brecciation and was unable to continue and did not reach the deeper sulphide mineralization.
• EL25026 was drilled to follow-up on hole EL25024. The hole was stopped at 45.5m depth in strongly weathered and leached diorites, as the rig suffered mechanical issues, and needed to be replaced, and therefore the hole could not be completed to depth. The hole intersected strongly argillic altered and weathered diorite with pervasive fracturing, disseminated pyrite. Several zones of quartz-pyrite-chalcopyrite veins were intersected with minor chalcocite, and sphalerite, but the drill was unable to reach the deeper sulphide mineralization.
• EL25027 was drilled at Berezski North and was designed to explore for the southern continuation of porphyry-style mineralization intersected by hole EL24005. The hole was collared in fine-grained diorites, and at 167.6m depth intersected a zone of tourmaline breccias with fragments of diorite and andesite with pyrite and chalcopyrite, before passing into fine-grained andesites, at 218m depth. From 289.2m to the end of the hole at 606m the hole intersected potassic and phyllic altered diorites. Mineralization occurred as tourmaline-chalcopyrite-pyrite breccias from 167.6m to 220m depth, where the hole intersected zones of porphyry-style veining, sheeted veins and disseminated patches of pyrite and chalcopyrite.
• Hole EL25028 was drilled to explore for the northern continuation of mineralization at Berezski Central. The hole was collared in a thick package of andesites and andesitic tuffs, with zones of local brecciation. Several post-mineral fine-grained andesite and basalt dykes were observed towards the end of the drill-hole. Alteration progresses from strong argillic in the upper section to phyllic at depth, with occasional zones of silicification, and mineralization is dominated by disseminated pyrite increasing locally within phyllic zones with minor chalcopyrite and molybdenite. The drillhole was closed at 574.8 m depth.

Exploration Update

Two drill-rigs have commenced drilling at Elemes, with the first two drill holes collared on the Berezski East target to follow-up on drill-hole EL24004 (138.8m grading 0.77 g/t Au and 0.09% Cu) and EL25019 (457.7m grading 0.61 g/t Au and 0.10% Cu). Two additional rigs are expected to arrive at the project in March.

Elemes Phase II Drill Program: Since June of last year, Arras Minerals has been advancing its 20,000m Phase II diamond drill program at the Elemes Project. Drilling was paused in late December for a scheduled winter break and recommenced in February. Nearly 10,000m were completed in 2025, and the strength of the results has prompted Arras to plan an expansion of the program to 30,000m, with completion targeted by the end of 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 copper-gold mine (~60 km northwest), which reported mined grades in Q1 2025 of 0.37% Copper and 0.20 g/t gold.¹

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 defined two extensive Cu-Mo-As geochemical anomalies: the Berezski and Aimandai Trends, both considered priority targets for follow-up exploration drilling. A Phase 1 drill program on the Berezski Trend in late 2024 returned high-grade porphyry/epithermal copper and gold mineralization in results announced in Q1 2025. A 20,000m Phase 2 drill program commenced in May 2025 which was expanded to 30,000 metres in January 2026 and is expected to be completed by the end of 2026.
