ARRAS MINERALS CONFIRMS THIRD PORPHYRY CENTER - DRILLS 115.7 METERS GRADING 1.44 G/T AU & 0.24 per cent CU AT THE BEREZSKI EAST TARGET (ELEMES PROJECT) IN KAZAKHSTAN

Arras Minerals Corp. has released the first results from the 2026 drill program at the Elemes project in northeastern Kazakhstan.

Drilling recommenced in late February and the first two holes were collared at the Berezski East target (Elemes project). Only five holes have been completed by Arras on this target which is evolving into the third porphyry centre discovered on the Berezski trend over the past two years.

Berezski East is a gold-rich porphyry system, emplaced along a northeast-southwest structural corridor. Mineralization consists of magnetite and quartz-sulphide veins and local bornite dissemination that appear to be outlined by a prominent magnetic high feature that can be traced along strike for at least 800 metres. Gold-copper mineralization has been encountered from surface down to more than 400 m depth with higher-grade intervals approaching and exceeding one gram per tonne Au over core lengths greater than 100 metres. In drill hole EL26031, a fault zone was intersected at 315 m depth after which a significant increase in brecciation along with increased potassic alteration and a notable increase in veining and copper-sulphide mineralization was encountered. This new zone reported higher copper values than had previously been encountered at this target and is potentially a new vector towards the core of the system.

Highlights include:

• EL25031: 115.7 m grading 1.44 grams per tonne Au (gold) and 0.24 per cent Cu (copper) starting from 317.3 m depth within a broader zone of 424.0 m grading 0.50 g/t Au and 0.12 per cent Cu starting from 9.0 m depth;
• Hole EL26031 intersected a broad zone of porphyry style alteration and mineralization across the entire hole starting from near surface and included a high-grade interval at depth after a fault zone intersected at 315 m depth where alteration and mineralization increased significantly;
• An extensive magnetic high, that can be traced for at least 800 m strike length, is associated with the Au-Cu mineralization at Berezski East and thought to be caused by the magnetite and quartz-sulphide veining hosting the gold-copper mineralization. To date, approximately 400 m of magnetic high has been drill-tested.

Tim Barry, chief executive officer of Arras Minerals, commented: "We are pleased to report the Berezski East target is firming up as a third porphyry centre on the Berezski trend. Hole EL26031 has confirmed and extended gold mineralization intersected by earlier drilling but importantly also intersected a major fault zone that appears to act as a key structural control on mineralization. Below this structure, there was a significant increase in the intensity of alteration, veining and mineralization indicative of a robust mineralized system. The five holes that we have drilled to date cover 400 metres of strike and the target, we believe, stretches at least a further 400 metres to the northeast." He went on to add, "We are planning a top-of-bedrock (KGK) drill program over the Berezski East target to help define the footprint of the gold-copper mineralization under the cover at this target that we will then follow-up with diamond drilling on priority targets here."

Drilling summary

Drilling at Berezski East continues to return wide zones of high-grade gold mineralization demonstrating the growing scale of this system. The mineralized zones are running northeast/southwest and are coincident with a linear magnetic high. However, results from the KGK drilling announced in December, 2025, has identified good gold values in the adjacent magnetic low to the east, suggesting several parallel gold systems in this area. Arras has completed five holes here which has confirmed strong Au-Cu mineralization over a 400 m strike length and to a depth of at least 400 m.

Hole EL26031 was particularly encouraging as it has extended mineralization to significant depths and confirms the presence of a large, vertically extensive porphyry-style hydrothermal system at Berezski East. It intersected wide zones of gold-copper mineralization, with alteration and vein density increasing significantly below a major fault zone intersected at 315 m down hole. This appears to demonstrate an important structural control on the mineralization which the company believes is the reason hole EL26030 only returned narrow zones of gold as it appears to have been drilled adjacent to this important structure.

Mineralization at surface consists of quartz-magnetite-chalcopyrite veinlets, with intervals of minor quartz B- and M-type veins. At 315 m depth, after a significant fault, the intensity of quartz-magnetite-chalcopyrite veining increases markedly, these veins were typically surrounded by halos disseminated chalcopyrite and minor bornite, that continued to 435 m depth, to a second fault zone, after which mineralization decreased.

The geology, alteration and mineralization logged at the top of this hole are consistent with the outer portions of a porphyry system, and the deeper mineralization could represent the core of this system.

Hole EL26030 was designed to test the northern continuation of the Berezski East Au-Cu mineralization. The hole intersected a thick sequence of fine- to medium-grained diorites and andesites. Alteration is dominated by moderate propylitic assemblages, with localized zones of potassic alteration at depth, and mineralization consists of very fine disseminated pyrite and chalcopyrite, along with intervals of D-type veining and localized bornite within M-type veins.

The geology, alteration and mineralization observed in hole EL26030 are consistent with the margins of a porphyry system, and the hole appears to have been drilled in the footwall of the structures that control the high-grade Au-Cu mineralization intersected in holes EL25019 and EL26031.

Exploration update

Four diamond drill rigs are now operating at Elemes. Three rigs are located at the Berezski North target and one rig recently commenced at the Novii target. To date, seven holes and nearly 5,000 metres have been completed at Elemes since drilling recommenced in late February with five holes pending assays.

Elemes phase II drill program: Since June of last year, Arras Minerals has been advancing its 20,000 m phase II diamond drill program at the Elemes project. Drilling was paused in late December for a scheduled winter break and recommenced in February. Nearly 10,000 m were completed in 2025, and the strength of the results has prompted Arras to plan an expansion of the program to 30,000 m, with completion targeted by the end of 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 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 (approximately 80 km east) and KAZ Minerals' Bozshakol copper-gold mine (approximately 60 km northwest), which reported mined grades in Q1 2025 of 0.37 per cent copper and 0.20 g/t gold.

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 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. A phase 1 drill program on the Berezski trend in late 2024 returned high-grade porphyry/epithermal copper and gold mineralization in results announced in Q1 2025. A 20,000 m phase 2 drill program commenced in May, 2025, which was expanded to 30,000 metres in January, 2026, and is expected to be completed by the end of 2026.

Quality assurance and quality control

The company adheres to CIM (Canadian Institute of Mining) Best Practices Guidelines for exploration related activities conducted on its property. Quality assurance and quality control (QA/QC) procedures are overseen by the qualified person.

Arras Minerals QA/QC protocols are maintained through the insertion of certified reference material (standards), blanks and field duplicates within the sample stream. Drill core is cut at Arras Minerals operations base in Ekibastuz, Kazakhstan, by company personnel. Diamond drill core was sawed in half with a diamond saw, and then sampled in maximum two-metre intervals, stopping at geological boundaries, with one-half placed in sealed bags and shipped to the laboratory and the other half retained on site.

Each bagged core sample was shipped to ALS Laboratory in Karaganda, Kazakhstan. Samples were dried, crushed and pulverized to greater than 80 per cent passing negative 200 mesh. The prepared sample splits were sent to the ALS Chemex's geochemical analysis laboratories laboratory in Loughrea, County Galway, Ireland, and Lima, Peru, for multielement analysis. Multielement analyses were analyzed with ICP-MS following a four-acid digestion (method ME-MS61) and samples containing greater than 1.0 per cent copper are analyzed via method Cu-OG62.

Gold analysis was conducted by ALS Chemex at the analytical laboratory in Karaganda, Kazakhstan. Gold was analyzed by fire assay (30 g) with an AA (atomic absorption) finish (method Au-AA23) with detection limits of 0.005 g/t gold. Samples containing greater than 10.0 g/t gold are analyzed by fire assay with a gravimetric finish (method Au-GRA21).

ALS is an accredited laboratory which is independent of the company. Chain of custody is maintained from the drill to the submittal into the laboratory preparation facility.
