TSX-V: ARK / OTCQB: ARRKF

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)(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 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.
