Arras Minerals Confirms Large “at Surface” Untested Porphyry System ON the Elemes Licence IN Kazakhstan
ARRAS MINERALS CONFIRMS LARGE “AT SURFACE” UNTESTED
PORPHYRY SYSTEM ON THE ELEMES LICENCE IN KAZAKHSTAN
February 22, 2024 TSX-V: ARK
Vancouver, British Columbia – Arras Minerals Corp. (TSX-V: ARK) (“Arras” or “the Company”) is pleased
to announce the initial results of its 2023 soil sampling program conducted over the Berezski Target
located within the Company’s Elemes 425 square kilometer (“km”) exploration licence (“Elemes” or the
“Licence”) in northeastern Kazakhstan. The Elemes licence is not included in the Teck-Arras Strategic
Exploration Alliance announced on December 7, 2023.
Highlights from the Soil Sampling program
8.8 km x 1.5km NE-SW trending coherent copper (“Cu”) anomaly (>150ppm) linking two zones of
shallow (<298m) high-grade historical drilling that sit 5 km apart and include re-assayed results of
108m @ 0.94% CuEq (including 30.8m @ 2.21% CuEq), and 132.6m @ 0.80% CuEq (including
57.1m @ 1.00% CuEq) starting from surface.
“Bull’s eye” 2.8 km x 1.6 km coherent Molybdenum (“Mo”) anomaly interpreted to be the core of
an at surface porphyry system that is untested with drilling.
An Arsenic (“As”) peripheral to copper-molybdenum anomaly thought to be associated with an
intermediate-sulphidation epithermal system which recent sampling by Arras has returned gold
and silver grades up to 29g/t Au & 287g/t Ag.
Results confirm a multi-kilometer-scale system, delimited by several mineralized zones which may
be contiguous under surface cover.
Arras collected 31,000 soil samples over the Elemes Licence in 2023. The results presented in this
news release cover only the western half of the Elemes Licence and represent approximately 60%
of the soil samples collected. The results of the remaining 14,000 soil samples are expected in the
next 3 to 4 weeks.
Tim Barry, CEO of Arras Minerals stated, “The coherence and continuity of the copper soil anomaly over
8.8 kilometers is impressive. The results of our soil sampling program combined with widely spaced
historical drilling, some of which we have been able to re-assay, all points to a very large and intact
porphyry system that starts at surface and has unknown extent as it continues under recent cover to both
the northeast and southwest. The re-assay results we put out at the start of this year on some of the
historical shallow drillholes in the area show strong copper-gold mineralization grading up to 0.94% CuEq
over 108m, and 0.80% CuEq over 132.6 meters, ending in mineralization in some cases. What is even more
exciting is that in addition to the copper soil anomaly, our soil results were also able to delineate a 2.8
kilometer by 1.6 kilometer “bull’s eye” molybdenum anomaly that has yet to be drill tested. The
significance of the molybdenum is that it may point towards the core of the porphyry which typically holds
high grade copper and gold mineralization. In summary, we now have a confirmed second large porphyry
system within our extensive licence package in NE Kazakhstan.”

The Soil Sampling Program: In 2023, a comprehensive soil sampling program was undertaken across the
Elemes Licence area. This program specifically targeted the well-developed "B soil horizon" utilizing a 50-
meter sample interval and 200-meter line spacing grid. A total of approximately 31,000 samples were
collected.
This press release announces the findings from the initial batch of 17,000 samples, which cover an area
of 189.3 sq. km (approximately 11.5 km by 18.2 km) situated on the western side of the Elemes Licence.
The results from the remaining 14,000 samples, covering the eastern portion of the Elemes Licence, are
anticipated to be available within the next 3 to 4 weeks.
The soil analysis was conducted utilizing a Portable X-ray fluorescence device ("pXRF"), a widely employed
instrument for determining the elemental composition of samples. Due to the limited sampling area of
the pXRF, the results presented in this release are considered "indicative" rather than fully quantitative
regarding mineralization.
Despite this limitation, the results have revealed a substantial and coherent copper-in-soil anomaly, with
copper concentrations exceeding 150 ppm. Background copper in the area is considered to be less than
20 ppm. This anomaly stretches over a remarkable distance of more than 8.8 km from north to south and
extends to approximately 1.5 km in width from east to west. Notably, it connects the Quartzite_Gorka
and Berezski East historical drilling areas, which are situated over 5 km apart. These areas have previously
confirmed high-grade porphyry copper-gold mineralization starting at the surface.
The continuity of the copper soil anomaly strongly suggests that the Quartzite-Gorka and Berezski-East
areas represent only a small part of a much larger porphyry copper-gold system.
Re-Assay of Historical Core: The Quartzite-Gorka and Berezski East areas were drilled between 2007 and
2010. All available drill-core have been re-logged in detail by Arras for lithology, structure, alteration, and
mineralization. The mineralization seen at both locations is interpreted to be the upper part of a porphyry
copper-gold mineralizing system. The mineralization comprises of sheeted and/or stockwork veining of
quartz-magnetite “A” veins with minor chalcopyrite-bornite ± k-feldspar halos; magnetite-only “M” veins;
and quartz-chalcopyrite veins. Locally disseminated patches of chalcopyrite, bornite and pyrite occur.
Anhydrite veins and late epidote-carbonate veins are also observed. The host diorite intrusion is fine-
grained, equigranular and typically highly magnetic. Strong potassic (k-feldspar-quartz-magnetite-
secondary biotite) alteration of the host diorite has been variably overprinted by intermediate argillic
(illite-chlorite) alteration.
Arras also sent 6 holes, three each from Quartzite-Gorka and Berezski-East for re-assay. The summarized
results of these re-assays are provided in Table 1 below and were disclosed in news releases on January
8, 2024, and January 22, 2024, respectively. Notably, the findings showcased zones of exceptionally high-
grade mineralization, including sections measuring 30.8 meters grading 2.21% CuEq and 62 meters
grading 1.53% CuEq. For further details, please visit www.arrasminerals.com.

Table 1. Summary table for the re-assay of historical drill holes for Quartzite-Gorka and Berezski-East
Notes: Copper Equivalent (“CuEq”) grades reported for the drill holes at Quartzite Gorka were calculated using the following formula: CuEq % =
Copper (%) + (Gold (g/t) x 0.8264) + (Silver (g/t) x 0.0107) + (Molybdenum (ppm) x 6.0000). Gold Equivalent (“AuEq”) grades reported for the drill
holes at Quartzite Gorka were calculated using the following formula: AuEq g/t = Gold (g/t) + (Copper (%) x 1.2100) + (Silver (g/t) x 0.0129) +
(Molybdenum (ppm) x 4.0334). Assumptions used for the copper and gold equivalent calculations were metal prices of US$3.00/lb. Copper,
US$1,700/oz Gold, US$22/oz Silver, US$18/lb. Molybdenum, and metallurgical recoveries were assumed to be 90% for Cu and Au and 50% for
Ag and Mo. Intervals are core-length weighted and original core recovery is estimated to be > 90 %.
The Berezski Target: is located within the 425 square km Elemes mineral exploration licence. The Licence
benefits from excellent modern infrastructure and ease of accessibility, being located only 20 km from
Arras’ operational base in the city of Ekibastuz, northeastern Kazakhstan. A paved highway runs through
the licence, and within 1 km of the Berezski target. 1100 KVA power lines and heavy rail all lie within a 15
km radius of the project.
The Berezski target is located within the Bozshakol-Chingiz metallogenic belt that also hosts the Beskauga
porphyry copper-gold-silver project approximately 80 km to the east, and KAZ Minerals’ Bozshakol
porphyry copper-gold mine (www.kazminerals.com) approximately 60 km to the northwest.

Sampling Methodology
Samples were collected on a 50m (East-west) by 200m (north-south) grid spacings. Samples were
collected from hand-dug pits, trying to consistently sample the B horizon. Approximately 500 grams of
material was collected and sieved (5mm mesh size) to review larger particles and organic matter.
Following collection, the samples were bagged, dried, and analyzed by the company with a Portable Niton
XL5 X-ray fluorescence analyzer at the company’s core storage facility in Ekibastuz.
Assay, QAQC Procedures:
Analysis was conducted using the company’s two Niton XL5 portable XRF units. Units were calibrated at
the start and end of each work shift as well as after every 100 samples to verify accuracy. In addition, a
measurement from a certified reference material was taken every 20 measurements to ensure accuracy
and repeatability of data. In addition, prior to commencement of the measurements, 100 duplicate
samples were analyzed using both units to confirm that both units were producing accurate results and
that no bias was present in either of the units.
All soil material is stored at Arras’ warehouse in Ekibastuz, and the company plans to send a proportion
of these samples to ALS Chemex in Karaganda, Kazakhstan for reanalysis with a 4-acid digest ICP-MS61
analysis and for trace gold analysis (using Au-ST43).
