ARRAS MINERALS DRILLS 935.9M GRADING 0.71% CUEQ FROM SURFACE INCLUDING 214.9M GRADING 1.42% CUEQ STARTING AT 162.1M DEPTH FROM THE BEREZSKI NORTH PORPHYRY TARGET, ELEMES PROJECT IN KAZAKHSTAN

Executive Summary

• Arras Minerals reported significant drill results from the Berezski North Target at its Elemes Project in Kazakhstan, confirming a large, preserved porphyry system open in multiple directions and to depths exceeding 900m.
• Hole EL26032 intersected 935.9m grading 0.71% CuEq from surface, including a high-grade 214.9m interval grading 1.42% CuEq starting at 162.1m depth, alongside 55m of high-grade breccia mineralization.
• The drilling program has expanded the target's geophysical and geochemical footprint to 3km x 2km, extended the high-grade breccia strike length to over 600m, and prompted an expansion of the 2026 drill program from 20,000m to 30,000m.

Key Details

• Hole EL26032: 935.9m grading 0.71% CuEq (0.51 g/t Au, 0.19% Cu) from surface, including 214.9m grading 1.42% CuEq (1.01 g/t Au, 0.41% Cu) starting at 162.1m depth. Terminated in mineralization.
• High-Grade Breccia (EL26032): 4.41% CuEq (3.27 g/t Au, 1.22% Cu) over 55.0m from 216.0m depth.
• Hole EL26033: 52m grading 1.75% CuEq (1.14 g/t Au, 0.64% Cu) from 259.0m depth, within a broader zone grading 181.0m at 0.66% CuEq (0.43 g/t Au, 0.24% Cu) from 170.0m depth.
• Distal Mineralization (EL26033): Terminates in distal porphyry-style mineralization grading 0.15% CuEq (0.11 g/t Au, 0.04% Cu) over 127.2m from 503.0m depth.
• Geological Context: Confirms a preserved, large, well-developed porphyry system open to depths >900m. Extended the strike length of high-grade breccias to >600m.
• Broader Berezski Trend (8.8 km): Berezski East target recently announced 115.7m grading 1.44 g/t Au and 0.24% Cu. Berezski Central previously announced 261m grading 0.64% CuEq from surface. K-Ozek target features 2km strike of quartz veins with historic grab samples >5 g/t Au; recent drilling intersected quartz-sulphide veins and wide stockwork veining.
• Drilling Program & Rigs: Four diamond drill rigs active on site. 8 holes completed at Berezski North since Q1 2026. 6 additional holes drilled with assays pending. Phase II program expanded from 20,000m to 30,000m in Jan 2026, targeting completion by end of 2026.
• Geophysics & Geochemistry: IP survey identified a 2km x 2km chargeability high anomaly. Ground magnetic data shows a coincident 2km x 2km doughnut-shaped magnetic low. Soil sampling (35,000+ samples) and UBC MDRU MPIx index highlight two large zones with high porphyry proximity, expanding the target footprint to 3km x 2km.
• Assay Parameters & Calculations: CuEq calculated using $3.75/lb Cu, $3,000/oz Au, $35/oz Ag, $30/lb Mo. Metallurgical recoveries: Cu 90%, Au 85%, Ag 75%, Mo 80%. All intervals reported as core lengths (true thickness unknown).
• Project Infrastructure & Location: Elemes Project covers 531 sq km in NE Kazakhstan, ~13 km SW of Ekibastuz. Features paved highway, 1100 KVA power lines, heavy rail, and utilities within 15 km. Located in the Bozshakol-Chingiz metallogenic belt near major regional deposits.

Notable Quotes

• Tim Barry, CEO: "These latest results from Berezski North represent a step-change for the Company. Intersecting more than 900 metres of porphyry-style mineralization from surface is a very significant result that has materially advanced our understanding of the scale and potential of this target."
• Tim Barry, CEO: "Importantly the system remains open in multiple directions and at depth. These drill results combined with the coincident 3 km x 2 km geophysical and geochemical footprint we observe in the data, suggests there is still significant potential to be unlocked at the Berezski North Target."
• Tim Barry, CEO: "Looking at the bigger picture along the entire 8.8-kilometer Berezski Trend... Arras currently has four diamond drill rigs on site focused on the Berezski Trend as part of its ongoing 20,000 m drill program this year."
