ARRAS MINERALS EXTENDS MINERALIZATION BY MORE THAN 200 METRES ON BEREZSKI CENTRAL TARGET - DRILLS 192 METRES GRADING 0.36 % CUEQ FROM 52m DEPTH

Arras Minerals Corp. announced drill results from the Berezski Central target of its Elemes Project in Kazakhstan. The results from two diamond drill holes, EL25018 and EL25020, indicate an extension of mineralization by more than 200 meters, expanding the known mineralized zone to approximately 600 meters by 500 meters.

Key intercepts include: - Hole EL25018: 192 meters grading 0.36 % CuEq from 52 meters depth (including 0.19 g/t Au). A deeper intercept also returned 9.4 meters grading 0.51 g/t Au from 564.6 meters. - Hole EL25020: 313.9 meters grading 0.14 % CuEq from 358.1 meters depth (including 0.14 g/t Au).

The company has completed 8,000 meters of the planned 20,000-meter Phase II drill program and 1,663 meters (64 holes) of a top-of-bedrock drill program. The CEO, Tim Barry, expressed continued strengthening confidence in the Berezski Central target due to the steady expansion of mineralization. CuEq calculations use US$3.75/lb Cu, US$3000/oz Au, US$35/oz Ag, US$30/lb Mo, and 90% recoveries.

This news release presents positive drill results that confirm the extension of copper-gold mineralization at the Berezski Central target of the Elemes project. The reported intercepts contribute to the understanding of the scale of the mineralized system, expanding its footprint. This is a favorable development as it builds on previous exploration success and aligns with the company's objective of delineating a large porphyry system.

However, when critically assessing the material impact in the context of prior news: - The headline intercept of 192 meters at 0.36% CuEq in EL25018, while good over a broad interval, is not as high-grade as some of the exceptional intercepts previously reported. For instance, the October 8, 2025 news highlighted 457.5 meters grading 0.63 g/t AuEq (including 231.0m grading 0.98 g/t AuEq) from surface at Berezski East. The September 8, 2025 news reported 276 meters grading 0.58% CuEq (including 104m grading 1.14% CuEq) from surface at Berezski North, and the August 27, 2025 news noted 154 meters of 1.09% CuEq at Berezski North. Even at Berezski Central, the August 13, 2025 news reported 440 meters grading 0.49% CuEq, and the January 15, 2025 news reported 261 meters at 0.64% CuEq. - The intercept in EL25020, at 313.9 meters grading 0.14% CuEq (0.14 g/t Au), is of a considerably lower grade, despite its length. While broad, such lower grades can impact the overall economic viability if they represent a significant portion of the resource. - The expansion of the mineralized area to 600m x 500m is a positive for scale, but the grade consistency across this larger footprint needs further high-grade intercepts to demonstrate robust economics. - The Phase II drill program is 40% complete (8,000m out of 20,000m), indicating steady progress.

Therefore, while the news is positive for extending the known mineralization and confirming the project's potential scale, it does not represent a significant step-change in the overall grade profile. It is a routine positive development in an ongoing exploration program, consistent with expectations of finding broad, varying grade mineralization in a large porphyry system. The stock price closed at $0.82 on Nov 3, prior to this news. The impact is likely neutral to slightly positive.

Arras Minerals Corp. (TSXV: ARK, OTCQB: ARRKF) is a Canadian exploration company focused on the discovery and development of large-scale copper-gold porphyry and epithermal deposits in Kazakhstan, a jurisdiction known for its significant mining potential.

Its flagship project is the Elemes Project in northeastern Kazakhstan. This project is strategically located approximately 61 kilometers southeast of KAZ Minerals' Bozshakol copper-gold mine, which has substantial reserves and production. Elemes encompasses several key targets along an 8.8-kilometer Berezski trend and a 14-kilometer Aimandai trend.

Key aspects and development of Elemes: - Exploration Approach: The company employs a comprehensive exploration strategy, including extensive soil sampling (over 35,000 samples), airborne and ground geophysical surveys (magnetic, IP, MT, gravity), KGK drilling (top-of-bedrock), and diamond drilling. - Drill Programs: Initial Phase 1 drilling (4,000 meters in late 2024) successfully identified significant copper-gold mineralization. This was followed by a more ambitious 20,000-meter Phase II drill program, which commenced in June 2025 and is ongoing, targeting extensions and new high-priority areas across multiple targets. - Key Targets & Results: - Berezski North: Notable intercepts include 547 meters grading 0.70% CuEq (Feb 2025), 154 meters grading 1.09% CuEq (Aug 2025), and 276 meters grading 0.58% CuEq (Sept 2025). - Berezski Central: Key intercepts include 261 meters grading 0.64% CuEq (Jan 2025), 578 meters grading 0.41% CuEq (Aug 2025), and the most recent 192 meters at 0.36% CuEq and 313.9 meters at 0.14% CuEq (Nov 2025), which has extended the mineralization. - Berezski East: Significant results include 304.8 meters grading 0.54 g/t AuEq (Jan 2025) and a standout 457.5 meters grading 0.63 g/t AuEq from surface (Oct 2025). - Other targets such as Q-Gorka, K-Ozek, and Novii are also being explored.

In addition to Elemes, Arras Minerals has a Strategic Alliance with Teck Resources Ltd. for generative exploration across a 1,736 square kilometer area in Kazakhstan. This partnership involves extensive geophysical surveys, soil sampling, and a planned 5,000-meter+ drill program on targets like Besshoky, Shirderty, and Taga-Ketti, focusing on various styles of mineralization including porphyry copper-gold. The option agreement for the Beskauga property was terminated in June 2025, with Arras opting to reallocate capital to other exploration opportunities.
