Vancouver, British Columbia – Arras Minerals Corp. (TSX-V: ARK, OTCQB: ARRKF) (“Arras” or “Arras Minerals”
or “the Company”) is pleased to report results of drillholes EL25012 and EL25013 from the 2025 drill program
currently underway on the Elemes Project in Northeast Kazakhstan. The program aims to test widespread
targets along the 8.8 kilometre Berezski Trend and the 14 kilometre Aimandai Trend.
Highlights include:
EL25012: 578m of mineralization grading 0.41 % copper-equivalent (“CuEq”) (0.14% Cu and 0.21 g/t
Au), starting at 3m depth; including:
440m grading 0.49% CuEq (0.16% Cu and 0.25 g/t Au) starting at 137m depth
114m grading 0.53% CuEq (0.22% Cu and 0.20 g/t Au) starting at 147m depth
252m grading 0.52% CuEq (0.15% Cu, and 0.29 g/t Au) starting at 325m depth
Tim Barry, CEO 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 underway 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 meters
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 5
kilometre gap between Berezski Central target and Berezski North target - which drilling, announced in February
of this year, intersected 547 meters of 0.70% 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 now been completed with the remainder of the assays
pending. A Magnetotellurics (“MT”) and Gravity geophysical survey is underway 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 &
EL24002 in 2024. Both holes drilled in 2024 were drilled towards the west, whilst Hole EL24012 drills towards
the east with the view of better constraining mineralization and the structures in the area. EL25012 was drilled
to a final depth of 724.3m, intersecting andesite and andesite breccias with pervasive argillic alteration
overprinting earlier phyllic alteration, along with localized silicification and veining. Below 526m, the intensity
2
of alteration diminishes, transitioning to remnant propylitic and weak phyllic assemblages. At 579.8m, a major
fault zone was encountered, marked by structurally controlled weak phyllic alteration and localized
silicification.
Mineralization is characterized by pervasive disseminated pyrite (1–3%) with quartz–pyrite veining, along with
minor chalcopyrite and molybdenite veins. Following the major fault at 579.8m, 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 86m depth, the hole transitioned into fine to medium-grained diorites. Argillic
alteration continues down to 126.9m, transitioning into weaker argillic assemblages, with several narrow zones
of phyllic alteration also noted. Mineralization is characterized by disseminated pyrite (0.5–3%, locally up to
5%), with minor disseminated chalcopyrite and rare galena.

Notes: Copper Equivalent (“CuEq”) grades reported for the drill holes at Elemes were calculated using the following formula: CuEq % = Copper (%)
+ (Gold (g/t) x 0.9167) + (Silver (g/t) x 0.0100) + (Molybdenum (ppm) x 4.2857). AuEq grades reported for the drill holes at Elemes were calculated
using the following formula: AuEq g/t = Gold (g/t) + (Copper (%) x 1.090858) + (Silver (g/t) x 0.0109) + (Molybdenum (ppm) x 4.6751). Assumptions
used for the copper and gold equivalent calculations were metal prices of US$3.75/lb. Copper, US$3,000/oz Gold, US$35/oz Silver, US$30/lb
Molybdenum, and metallurgical recoveries were assumed to be 100%.
