ARRAS MINERALS DRILLS 440 METERS GRADING 0.49% CUEQ INCLUDING 252 METERS GRADING 0.52% CUEQ ON BEREZSKI CENTRAL TARGET

Arras Minerals Corp. has released results of drill holes EL25012 and EL25013 from the 2025 drill program currently under way on the Elemes project in northeastern Kazakhstan. The program aims to test widespread targets along the 8.8-kilometre Berezski trend and the 14-kilometre Aimandai trend.

Highlights include:

• EL25012: 578 metres of mineralization grading 0.41 per cent copper equivalent (0.14 per cent copper and 0.21 gram per tonne gold), starting at three-metre depth, including:
  • 440 m grading 0.49 per cent CuEq (0.16 per cent Cu and 0.25 g/t Au) starting at 137-metre depth;
  • 114 m grading 0.53 per cent CuEq (0.22 per cent Cu and 0.20 g/t Au) starting at 147-metre depth;
  • 252 m grading 0.52 per cent CuEq (0.15 per cent Cu and and 0.29 g/t Au) starting at 325-metre depth.

Tim Barry, chief executive officer of Arras Minerals, stated: "Arras has three drill rigs currently turning across our licence package in northeast Kazakhstan. Two of the drill rigs are working on the Elemes project, and the third is following up targets identified on the Arras-Teck exploration alliance properties. The initial pass of the phase 2 drill campaign currently under way on the Elemes project aims to build on the success of our 2024 drill campaign and continue to target a wide variety of areas along the 8.8-kilometre Berezski trend and the 14-kilometre Aimandai trend. Hole EL25012 represents an excellent start to the phase 2 program intersecting the thickest interval of gold-copper mineralization encountered to date at Berezski Central, highlighting the scale and depth potential of the system. We now plan to focus one rig at Berezski Central to commence a systematic drilling program with an aim to further enhance understanding of structural controls and build scale at this target."

He went on to add: "Hole EL25013 is also very encouraging. While lower grade, it intersected nearly 300 metres of porphyry-style mineralization, 1.7 kilometres north of EL25012, demonstrating widespread thick pervasive mineralization along the Berezski anomaly. Furthermore, hole EL25013 is the first drill hole to test the five-kilometre gap between Berezski Central target and Berezski North target -- which drilling, announced in February of this year, intersected 547 metres of 0.70 per cent CuEq starting from 14 metres."

Arras 2025 drill program: Since late June, Arras has had two diamond drill rigs operating on the Elemes project targeting the Berezski trend. The initial pass on the 20,000-metre phase 2 drill program has the goal of building on the 2024 drill program through continuing to test a broad suite of known anomalies and new targets across the 8.8-kilometre Berezski trend. Seven holes have been completed with the rest of the assays pending. A magnetotelluric and gravity geophysical survey is under way across portions of the Berezski and Aimandai trends. This survey is expected to continue into September-October and, once finished, will be used to further refine drill targets in both areas.

Hole EL25012: targets the extensive copper-molybdenum soil anomaly first tested with holes EL24001 and EL24002 in 2024. Both holes drilled in 2024 were drilled toward the west, whilst hole EL24012 drills toward the east with the view of better constraining mineralization and the structures in the area. EL25012 was drilled to a final depth of 724.3 metres, intersecting andesite and andesite breccias with pervasive argillic alteration overprinting earlier phyllic alteration, along with localized silicification and veining. Below 526 m, the intensity of alteration diminishes, transitioning to remnant propylitic and weak phyllic assemblages. At 579.8 m, a major fault zone was encountered, marked by structurally controlled weak phyllic alteration and localized silicification.

Mineralization is characterized by pervasive disseminated pyrite (1 to 3 per cent) with quartz-pyrite veining, along with minor chalcopyrite and molybdenite veins. Following the major fault at 579.8 m, quartz veining becomes markedly less common. Near-surface intervals contain zones of disseminated and patchy chalcocite, suggesting the surface has been leached in areas and highlights the presence of potential supergene mineralization at Berezski Central.

Hole EL25013: targets a prominent copper-in-soil anomaly located 1.7 kilometres north of EL25012. The hole intersected medium-grained, fractured andesites overprinted by moderate argillic alteration with remnant propylitic alteration. At an 86-metre depth, the hole transitioned into fine- to medium-grained diorites. Argillic alteration continues down to 126.9 m, transitioning into weaker argillic assemblages, with several narrow zones of phyllic alteration also noted. Mineralization is characterized by disseminated pyrite (0.5 to 3 per cent, locally up to 5 per cent), with minor disseminated chalcopyrite and rare galena.

Elemes project overview: The Elemes project comprises two exploration licences covering 531 square kilometres in northeastern 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-kilometre radius.

Situated within the prolific Bozshakol-Chingiz metallogenic belt, Elemes lies near significant regional deposits, including the Beskauga porphyry copper-gold-silver deposit (approximately 80 kilometres east) and Kaz Minerals' Bozshakol mine (approxiomately 60 kilometres northwest), which produced 104,700 tonnes copper and 104,000 ounces gold in 2024.

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 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.
