ARRAS MINERALS DRILLS 154 METERS GRADING 1.09% CUEQ INCLUDING 118 METERS GRADING 1.38% CUEQ ON BEREZSKI NORTH TARGET

Arras Minerals Corp. has released results from drill holes EL25014, EL25014A and EL25015, part of the continuing 2025 drill program at 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:

• EL25014A: 154 m of mineralization grading 1.09 per cent copper-equivalent (CuEq) (0.29 per cent Cu and 0.72 g/t Au), starting at 130 m depth; including:
  • 118 m grading 1.38 per cent CuEq (0.36 per cent Cu and 0.91 g/t Au) starting at 130 m depth;
  • 24 m grading 2.32 per cent CuEq (0.42 per cent Cu, 1.73 g/t Au) starting at 144 m depth.
• Results confirm the presence of a large, well-developed hydrothermal system along the Berezski 8.8-kilometre Berezski trend.

Tim Barry, chief executive officer of Arras Minerals, commented: "Hole EL25014A underscores the quality of copper and gold mineralization at the Berezski North target and continues to confirm the scale of the mineralized system we are drilling into. This hole was collared approximately 300 m northwest of hole EL24005 which reported 547 m at 0.70 per cent CuEq starting from 14 m and announced in our Feb. 11, 2025, news release. Hole El25016 as outlined in Figure 2 [in the original version of this release] is collared approximately 300 m to the SE of hole El25014A and, once assay results are available for this hole, we will then review next steps for the Berezski North target." He continued: "This result builds on our recent announcement of 578 metres at 0.42 per cent CuEq from the Berezski Central target, located approximately five kilometres to the south. Together, these intercepts highlight the district-scale potential of the Elemes project. With only a small portion of our phase II drilling completed along the 8.8-kilometre copper-in-soil anomaly that defines the Berezski trend, we believe there remains substantial upside yet to be tested. The presence of thick mineralized intercepts often starting at surface and with broad zones exceeding 0.8 per cent CuEq at Berezski North is particularly encouraging. We're excited to build on this momentum as we advance what we view as one of the most compelling copper-gold exploration opportunities in Kazakhstan."

Results from this news release are shown in the attached table.

A summary of each hole is outlined below.

Hole EL25014A: The first attempt of hole EL25014 was abandoned at 30 m when drilling intersected a highly weathered fault zone. A second version of the hole, EL25014A, was successfully completed, collared 10 m to the northeast of the original hole. Hole EL25014A was designed to test the westward extension and structural controls of the hydrothermal breccia pipe that hosts the copper-gold mineralization previously encountered in hole EL24005. Collared 300 m northwest of EL24005, hole EL25014A intersected weak to moderate propylitically altered diorite to 147 m before entering a hydrothermal diorite-andesite breccia between 147 m to 284 m, cemented by a tourmaline-pyrite matrix with plus or minus chalcopyrite and overprinted by strong argillic alteration. Below the breccia, drilling passed into a strongly propylitically altered andesite, which continued to the end of hole at 334.7 m.

Mineralization from surface to 130 m consisted mainly of disseminated pyrite with rare pyrite-chalcopyrite patches. Between 130 m and 284 m, mostly within the breccia, sulphide content increased significantly, with strong pyrite-chalcopyrite mineralization observed throughout.

Hole EL25015: Hole EL25015 was located one kilometre to the north of the Berezski North target and drilled to test a copper-molybdenum soil anomaly associated with a magnetic low feature within the 8.8-kilometre Berezski trend. The hole intersected a sequence of propyllitically altered andesites, crosscut by several diorite dikes before the hole intersected a large weak to moderate propylitically altered diorite body at 228 m to the end of the hole at 499.5 m. Weak mineralization is hosted along localized quartz-sericite-pyrite alteration zones with associated minor quartz veins.

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, eight 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 continuing into 2026.

Elemes project overview: The Elemes project comprises two exploration licences 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 1,100-kilovolt-ampere 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 (about 80 km east) and KAZ Minerals' Bozshakol mine (about 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 (copper-molybdenum-arsenic) 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.
