VANCOUVER, BC / ACCESS Newswire / February 11, 2025 / Arras Minerals Corp. (TSX-V:ARK)(OTCQB:ARRKF) ("Arras" or "Arras Minerals" or "the Company") is pleased to announce the results from the final five holes from its initial "Phase 1" drill program targeting the 8.8 kilometre long Berezski target located on its Elemes project in Northeast Kazakhstan. The first 11 holes of the Phase 1 drill program encountered thick intercepts of widespread copper-gold and gold porphyry and/or epithermal-style mineralization.

The Elemes project is in the Bozshakol-Chingiz Magmatic arc and is 61 kilometres ("km") southeast of Kaz Mineral's Bozshakol Copper Mine, that commenced operations in 2016 and in 2023 produced 105,000 tonnes "t" of copper "Cu" & 115,000 oz gold "Au" at US$0.95/lb Cu (net) cash costs. Reported reserves are 1.003 billion tonnes @ 0.33% Cu & 0.13 g/t Au.

Highlights

• EL24005: 547m of mineralization grading 0.70 % copper-equivalent ("CuEq") (0.23% Cu & 0.48 g/t Au), starting from 14m depth; including:

  • 44m grading 1.15% CuEq (0.48% Cu & 0.64 g/t Au) starting from 14m depth

  • 206m grading 0.83 % CuEq (0.27% Cu & 0.54 g/t Au) starting from 24m depth

  • 58m grading 1.02% CuEq (0.32 % Cu & 0.69 g/t Au) starting from 172m depth

  • The hole ended in strong mineralization grading 64.8m at 0.68 % CuEq (0.16% Cu & 0.55 g/t Au)

• EL24006: returned 56m grading 0.68% CuEq (0.36% Cu & 0.33 g/t Au) starting from 4m depth, including:

  • 20m grading 1.02%CuEq (0.72% Cu & 0.32 g/t Au) starting from 40m depth

• EL24010: returned 152m grading 0.13 % CuEq (0.07% Cu & 0.06 g/t Au) starting from 262m depth

• EL24011: returned 76m grading 0.20 % CuEq (0.06% Cu & 0.14 g/t Au) starting from 247m depth

Tim Barry, CEO of Arras Minerals, commented, "We are extremely encouraged by the results of the Phase 1 drill program at Elemes. Holes EL24005 and EL24006 strongly suggest the presence of another porphyry center developing at the Berezski target. Notably, the porphyry-style mineralization identified in quartz-chalcopyrite veining in the deeper sections of EL24005 provides a solid vector for us to pursue in the Phase 2 program. Furthermore, EL24006 intersected porphyry-style mineralization approximately 1 km to the west, on the western edge of the copper soil anomaly, giving us follow-up targets between the two holes, as well as to the west, north, and south-even beyond the current anomaly boundaries."

He went on to add, "Over the last three field seasons, we've significantly advanced the Elemes-Aimandai licenses from an initial 530 sq km land package to identifying two major copper targets spanning nearly 9 km at Berezski, and 14 km at Aimandai. Our drilling this past year has confirmed at least two porphyry centers on the Berezski target, approximately 5 kms apart, with associated epithermal mineralization along the eastern boundary. With roughly 90% of the Berezski target still open and untested, the early success of Phase 1 gives us a strong foundation to hone in on two key areas, while continuing to develop additional high-priority targets across this large, highly prospective region."

The Elemes Phase 1 Drill Program: The Phase 1 drill program targeted geophysical and geochemical anomalies identified by the Company's extensive airborne magnetic, ground pole-dipole induced polarization ("IP") surveys, and greater than 35,000 soil samples collected in 2022, 2023 and 2024, that identified several distinct porphyry-epithermal exploration targets. Additionally, historical drilling at the Berezski East and Berezski North were reviewed when possible.

Historic shallow drilling at Berezski North identified an area of mineralized structurally controlled hydrothermal breccia that has been overprinted by later low temperature epithermal quartz veins and mineralization. The Company believed that these breccias represent the lower temperature top to a porphyry copper system, and hole EL24005 was the first deep drill-hole in this target to test this hypothesis. The Company was pleased that the hole appears to have tapped into the mineralized root of these breccias, and the mineralization intersected by the hole appears to transition from low temperate epithermal dominant mineralization at surface to higher-temperature porphyry-style mineralization at depth.

Drill hole EL24006 was drilled approximately 1km to the west of hole EL24005. This hole appears to have identified another target with porphyry style mineralization and alteration. The hole intersected propylitic altered diorites that have been partially overprinted by argillic alteration. Mineralization is present as quartz-pyrite-chalcopyrite porphyry-style veins, with disseminated pyrite and chalcopyrite.

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$3.50/lb. Copper, US$2,200/oz Gold, US$24/oz Silver, US$15/lb. Molybdenum, and metallurgical recoveries were assumed to be 100%.

DRILL-HOLE SUMMARIES

Drill-hole EL24005 was designed to test a Cu-Mo soil anomaly at Berezski North that had a coincident annular magnetic low and high chargeability Induced Polarization ("IP") anomaly. The drill-hole collared in hydrothermal breccias with visible copper-oxides and intersected diorites with moderate argillic alteration in first 200m, where it passes into moderate potassic/sodic altered diorites. Within the diorites are intervals of hydrothermal breccias cemented by tourmaline and pyrite.

Near surface mineralization is characterized by massive pyrite patches with minor copper oxides on fractures, zones of quartz-pyrite veins containing minor chalcopyrite. With depth, chalcopyrite content increases up to 3%, with areas of sheeted chalcopyrite veins are narrow zones of massive chalcopyrite in patches and fractures with rare sphalerite and galena. The drill hole ended in mineralization.

Drill-hole EL24006 was designed to test an area significant magnetic low, a coincident chargeability high anomaly adjacent to the Berezski North target. The hole was collared in diorite with moderate inner propylitic and occasional local weak potassic alteration. From 218.0m to 285.2m the hole continued through brecciated and altered limestones with minor disseminated pyrite and chalcopyrite. From 285.2 to the end of the hole, it intersected weak to moderate propylitic altered diorites and occasional layers of limestone.

Drill-hole EL24007 was drilled to test a coincident magnetic high and resistivity high to the north of the Berezski North target. The hole intersected basaltic andesites with weak to moderate propylitic alteration and local structurally controlled zones of argillic alteration.

Drill hole EL24010 was designed to test an adjacent copper-molybdenum soil geochem anomaly located to the northwest of drill hole EL24005. The hole intersected weak potassic altered diorites over its entire length. Mineralization mainly consists of minor quartz-pyrite+/-chalcopyrite veins, with occasional quartz-magnetite-chalcopyrite veins. The mineralization, alteration and veining style suggests that the hole was drilled peripheral to a porphyry-epithermal target and has provided important information to help guide future drilling at the Berezski North target.

Drill-hole EL24011 was designed to explore a molybdenum soil anomaly located approximately 300m to the east-northeast of hole EL24002. The hole was collared in propylitic altered andesite breccias that have been overprinted by moderate argillic alteration. At 169.5m depth, the hole intersected phyllic altered diorites to the end of the hole. Mineralization is dominated by disseminated pyrite with rare quartz-pyrite veins indicating that it was drilled in the periphery of a porphyry system. Unfortunately, the hole was lost at 350.2m depth when it intersected a strong fault zone.

Phase 2 Elemes Program Plan

Final review and planning is underway for a Phase 2 drilling program at Elemes. The success of Phase 1 identifying and confirming at least two porphyry centers for follow up along with approximately 90% of the Berezski target remaining open and untested provides for significant opportunities to follow up in 2025.

Subject to the necessary financing in place, the Company believes that a Phase 2 program will comprise of:

• Ground magnetic survey focusing on the Berezski and Aimandai Targets to help with structural interpretation and target generation

• Full analysis of select soil samples collected in 2023 and 2024 over high priority targets to provide data on porphyry pathfinder elements to allow for vectoring towards the porphyry center and allow for lithogeochemistry and alteration mapping.

• Approximately 20,000m of core drilling targeting key priority areas at the Berezski target

• Initial Vector IP geophysical survey at the Aimandai target with intention to identify priority drill targets

• An approximate 5,000m initial drill program at the Aimandai target

Darren Klinck, President of Arras Minerals commented, "We are excited about the initial outcomes from the Phase 1 program at the Berezski target on our Elemes project. There are two high priority areas to focus on at Berezski Central and Berezski North where we plan to undertake systematic grid drilling following a ground magnetic survey this spring. In addition, with approximately 90% of the Berezski target still untested, we also expect to be testing new target areas as well. Furthermore, while we paused additional follow up work at the Aimandai target in 2024, with the positive results we have generated from Berezski in the Phase 1 program, we plan to undertake geophysical surveys to help identify priority drill targets for an initial drill program at that 14km copper-in-soil anomaly later this year."

Mr. Klinck went on to add, "It is very pleasing to see the systematic exploration work from the team over the past 2-3 years paying dividends. With the opportunities emerging at Elemes combined with the multiple targets we expect to be drill testing on the Arras-Teck Exploration Alliance licenses this year, we plan to have at least two core drills operating across the license package starting in Q2. Arras is in a unique position to have 6 to 9 target areas that we expect to be drill testing across the entire license package this year with all of these being prospective for copper-gold porphyries."

Elemes Project: Drilling commenced in September 2024 and the Phase 1 program was completed in late December 2024. This program of approximately 4,000 meters of diamond drilling has generally focused on priority targets at Berezski Central, Berezski East, Berezski North and K-Ozek targets. These targets were identified following two field seasons of comprehensive exploration work at the Elemes Project, including airborne magnetic and Pole-Dipole IP geophysical surveys, as well as extensive soil sampling and mapping. In addition, some historical drill holes from the Berezski East and Quartzite-Gorka (Berezski North) targets were re-assayed with those results reported in January 2024 (see Arras new releases January 8 & 22, 2024).
