Arras Minerals Corp. (TSX-V: ARK) (OTCQB: ARRKF) is pleased to announce drill results from the Berezski East Target at the Elemes Project. Hole EL25019 delivered wide zones of high-grade gold-copper mineralization starting at surface. This hole underscores the scale potential that is developing in the Berezski Central – Berezski East area of the Elemes Project.

Highlights include:

• EL25019: 457.50m of mineralization grading 0.63 g/t gold-equivalent (“AuEq”) (0.61 g/t Au and 0.10% Cu), starting at surface; including:
  • 231.0m grading 0.98 g/t AuEq (0.97 g/t Au, 0.13% Cu) starting from surface
  • 91m grading 1.77 g/t AuEq (1.79 g/t Au, 0.19% Cu) starting at 88m depth
• EL25017: 37.0m of mineralization grading 0.13 g/t gold-equivalent (“AuEq”) (0.11 g/t Au and 0.02% Cu)
  •  9.5m of mineralization grading 0.55 g/t AuEq (0.48 g/t Au, 0.08% Cu)

Tim Barry, CEO of Arras Minerals, commented: ” Drillhole EL25019 has delivered an exceptional high-grade gold-copper intercept from surface, confirming Berezski East’s strong potential to host broad zones of high-grade mineralization. Broad zones of potassic alteration and the presence of copper minerals such as bornite and chalcopyrite suggests this target may form part of a larger porphyry system — a highly encouraging development. When we look at the area between Berezski Central and Berezski East, we continue to see the potential for continuity and scale. Additional holes are being planned at Berezski East, and we already have a focus at Berezski Central with one dedicated drill rig currently operating there.”

Results from this news release include:

Hole EL25017 was designed to follow-up on mineralization intersected in hole EL25013 (192m grading 0.18 g/t AuEq), that targets a prominent copper-in-soil anomaly located 1.7 kilometers north of the Berezski Central target. The hole was collared in fine to medium grained andesite breccias. At 105.7m depth, the hole passed into andesites to the end of the drill-hole at 250.5m depth. Alteration is dominated by argillic overprinting earlier propylitic and phyllic alteration. Mineralization is characterized by disseminated pyrite (0.5–3%, locally up to 5%), with minor zones of pyrite D-type veins.

The character and intensity of the mineralization intersected in hole EL25013 and EL25017 appear to represent the distal part of a porphyry Cu-Au system. Company geologists are reviewing the data collected in this area to determine if mineralization is related to the Berezski Central system located 1.7km to the south.

Hole EL25019 was drilled approximately 250m north from EL24004 (86.8m grading 0.97 g/t AuEq) on the Berezski East Target. The hole intersected 457.7m of fine-grained grey-greenish-grey diorites. Alteration was dominated by potassic alteration with alternating intensity of K-feldspar and biotite down the hole.

Mineralization consists of disseminated and patchy pyrite with minor zones of bornite and chalcopyrite mineralization. Several intense zones of hematite-magnetite and k-feldspar-quartz veins were intersected with associated pyrite, chalcopyrite and bornite.

Earlier this year, drill results from Berezski East confirmed broad zones of gold mineralization, thought to be related to a robust epithermal gold system. The discovery of copper sulfides (chalcopyrite and bornite) and broad zones of potassic alteration in hole EL25019 has highlighted a new style of mineralization, indicating that Berezski East may be situated on the margin of a larger porphyry Cu-Au system. To further advance this target, the company has undertaken detailed MT and gravity surveys and will commence a high-density top-of-bedrock drill program in the coming weeks. Preliminary results from the gravity survey have been partially received and the results from the MT survey are expected in November. This program is designed to provide critical information on the geometry and scale of the system and to guide the next phase of exploration of this target.

Exploration Update

At the Novii target, which is located 4.4 km southwest of Berezski Central, Arras has completed three drill-holes totalling 1000m, focusing on a 2.5 x 1.5-kilometre area defined by strong arsenic-in-soil anomalies and hematite-filled fractures (see Figure 5). The program intersected layers of volcanic and limestone rocks. Notably, hole NOV25001 encountered zones of massive sulphide mineralization within faults and fractures, while hole NOV25003, targeting the southern continuation of the magnetic low associated with mineralization at Berezski Central, intersected brecciated andesites and diorites beneath the volcanic cover containing porphyry-style mineralization, including B-type quartz-molybdenite veins and finely disseminated chalcopyrite. Assays are pending and expected next month.

Due to the discovery of porphyry-style mineralization in hole NOV25003, the gravity and MT surveys have been expanded by an additional 102 stations to cover this new target area (Novii). The field work for this survey will continue to the end of October.

The company has also received preliminary results from the gravity survey conducted over the Berezski Central and Berezski East targets, and the findings are highly encouraging. The data (see Figure 2) reveals a pronounced gravity low coincident with the copper-gold mineralization at Berezski Central. A second gravity low has been identified immediately northeast of hole EL25019, supporting the company’s interpretation that the copper-gold mineralization and potassic alteration intersected indicates that this hole cold be proximal to the core of a mineralized porphyry system, in contrast to the lower-temperature, gold-only mineralization encountered in hole EL24004.

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, sixteen holes totaling more than 6,000m, have been drilled. 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 continue into 2026.

Elemes Project Overview: The Elemes Project comprises two exploration licenses 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 1100 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 (~80 km east) and KAZ Minerals’ Bozshakol mine (~60 km northwest)¹.

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 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.
