VANCOUVER, BC
,
Dec. 16, 2025
/CNW/ -
Arras Minerals Corp.
(TSXV: ARK) (OTCQB: ARRKF)
("Arras" or "Arras Minerals" or "The Company")
is pleased to announce results from the top of
bedrock (KGK) drilling over the Berezski Central and Berezski East targets along with three diamond
drill holes at the Novii target that appear to have potentially defined a new porphyry system 1.6 km
to the southwest of the Berezski Central target. These results have expanded significantly the
prospectivity of the Berezski Trend to the south where the soil copper and molybdenum anomalies
disappear below cover. Two drill rigs are currently operating on the Berezski Trend.
Highlights include:
KGK drilling successfully expanded the Berezski East footprint to >
1,000 m
of strike length
Northern and southern extensions of the Berezski Central target identified
Multiple new Cu-Au mineralized zones discovered between known targets
Drill hole NOV25003 intersected porphyry-style mineralization 1.6 km southwest of Berezski
Central, indicating a >2 km southern extension of the Berezski Trend under cover
Gravity data shows strong correlation between mineralization and gravity lows
Matt Booth
, Vice President of Exploration commented,
"We are now seven months into the first
major drill program at Elemes, and we are continuing to be surprised by the size potential and
quality of the various targets along the Berezski Trend. The KGK drilling, just testing a
1000 m
section of the 8.8 km long Berezski Trend has shown that these systems continue for at least
1000
m
along strike, and may have identified additional exploration targets adjacent to the known
targets. The KGK drilling has been an excellent tool, and we plan to use this technique in 2026 to
define the extents of known mineralization and to rapidly explore the entire length of the 8.8 km
long Berezski Trend to see if it hosts additional mineral systems."
Mr. Booth went on to add,
"Stepping out up to 6.4 km to the southwest of Berezski Central at the
Novii target also identified a mineralized hydrothermal system approximately 1.6 km south of the
southernmost hole at Berezski Central. With coincident gravity and magnetic lows, consistent with
Berezski Central, we will use the recently completed MT survey as well to prioritize follow-up drill
targets."
Top of Bedrock (KGK) Drilling at Berezski Central and Berezski East
Preliminary data from the Berezski gravity survey identified that the Berezski Central and Berezski
East targets may be part of much larger system. However, the minimal outcrop exposure in the area
has made geological mapping challenging, and in October, a 64-hole top-of-bedrock (KGK) drill
program, totaling
1,663 m
was completed over these targets.
The program was designed to rapidly evaluate the geology and mineralization found beneath shallow
cover in this area, and to evaluate if KGK drilling would be a useful technique to rapidly evaluate the
8.8 km-long Berezski Trend to see if it hosts additional Cu-Au zones.

The KGK drilling program delivered strong results, materially expanding the copper-gold mineralized
footprint at the Berezski Central and Berezski East targets to over
1000 m
of strike length and
indicated that the mineralization was still open to the north and south.
The KGK drilling also identified several previously unknown zones of gold mineralization between the
Berezski Central and Berezski East, demonstrating potential beyond the known target areas as
shown in Figure 2.

Novii Target
Three holes, totaling
922.2 m
, were completed at Novii. Holes NOV25001 and NOV25002
intersected interbedded volcaniclastics and sediments with zones of pyrite mineralization. However,
drill-hole NOV25003, testing a major magnetic low and the margins of a large gravity low,
intersected a similar setting hosting mineralization at the Berezski Central and Berezski East targets.
Hole NOV25001:
This hole was drilled 4.3 km to the southwest of the Berezski Central target. The
hole Intersected a thick package of andesites and volcaniclastics with several narrow breccia zones,
and with weak alteration and minor disseminated pyrite.
Hole NOV25002:
This hole was drilled 6.4 km to the southwest of the Berezski Central target. The
hole intersected a thick sequence of sediments, interbedded siltstones and limestones, before
passing into a sequence of lithic tuffs with weak alteration and minor pyrite.
Hole NOV25003:
This hole is located approximately
1,600 m
southwest of Berezski Central. The
hole was collared in weakly propylitic altered volcano-sedimentary rocks to
190 m
depth, where the
hole passed into argillic altered diorites, with local relict K-Feldspar and quartz alteration. The
diorites were cut by several breccia zones, that included fragments of B-type veins. Mineralization is
dominated by disseminated pyrite with minor chalcopyrite starting from
100 m
depth and continuing
to the end of the drill-hole.
Figure 3. Elemes ground magnetic survey and gravity low contour with location of drill holes
NOV25001, NOV25002, NOV25003 (CNW Group/Arras Minerals Corp.)
The Company believes that this discovery of porphyry-style mineralization in NOV25003, 1.6 km to
the southwest of Berezski Central, suggests it has intersected the margin of a previously
unrecognized porphyry system, which is strongly supported by the ground magnetic survey data.
This hole is also located on the eastern edge of the gravity low anomaly. The new data from
NOV25003 supports the theory that the Berezski Trend is much larger than originally thought and
supports the idea that there is a thin cover unit masking the southern extension of the 8.8 km long
copper-in-coil anomaly to the south of Berezski Central. Further drill testing of the Novii target will be
planned in accordance with expected results of the MT survey.

2025 Year End Exploration Update
The Company commenced field work at Elemes in April following the successful completion of a
C$16 million
equity financing earlier that month. The program focused on the entire license package
not part of the Arras-Teck Exploration Alliance. Results from the Arras-Teck Exploration Alliance are
being reviewed and analyzed with our partner and we expect to provide an update in January or
February 2026
.
Tim Barry
, CEO commented,
"Since announcing results from our initial Phase 1 drill program at
Elemes only 11 months ago, we have continued to methodically advance our activities,
progressively increasing as we improve our understanding of the geologic controls of the
hydrothermal systems we are working on across the Berezski Trend. We continue to regularly
encounter potential mineralization extensions in newly drilled areas and have been impressed with
the broad intervals of mineralization that we are seeing so far, despite predominantly being in the
phyllic alteration zones of the systems."
Mr. Barry went on to say,
"We believe we are only scratching the surface on potentially very
significant mineralized hydrothermal systems and plan to continue to scale up our activities
progressively in 2026 as our understanding further advances."
Elemes Project
Berezski Trend:
The 8.8 km Berezski Trend located within the Elemes Project licence package was
the primary focus of exploration by Arras in 2025. The program was designed to expand and follow-
up on the excellent results from the 2024 drilling campaign. A summary of the 2025 Exploration
campaign is outlined below.
2025 Exploration Summary Highlights:
Completed a 64.9 sq km Vector Induced Polarization survey over the Aimandai Trend
Completed a 24.6 line-km Pole-Dipole Induced Polarization survey at Aimandai exploration
targets
Completed 26 holes totaling approximately
10,000 m
of core drilling on the Berezski Trend.
Completed a 64 hole,
1,663 m
top of bedrock (KGK) drill program over the Berezski
Central/Berezski East target areas.
Completed 75 sq km Magnetotellurics (MT and Gravity surveys over the high-priority areas of
the Berezski and Aimandai trends
Geophysics
: Preliminary results from the gravity survey have been very encouraging. The gravity
survey identified several broad gravity lows that appear to be associated with the mineralization
intersected at Berezski Central and Berezski East and may appear to be mapping out the large
alteration footprints of these systems. Encouragingly, the survey identified several untested gravity
lows that could suggest additional porphyry-hydrothermal systems along the Berezski Trend. While
early, we believe this to be potentially an important new vector we can follow to further targets to be
drilled in 2026.
The high pyrite content observed in the drill core from the Berezski drilling suggests that the
effectiveness of IP surveys at the Berezski Trend may be limited. The Company believed that an MT
survey may be more effective on identifying anomalies under cover and at depth, and as a result, the
Company completed a 75 sq km MT survey. The data collection for this survey was completed in
October 2025
, and the Company is expecting to receive the results from a third party in December
and will be used for further drill targeting in the New Year.
Top of Bedrock Drilling (KGK):
A 64-hole top-of-bedrock (KGK) drill program, totaling
1,663 m
,
was completed over these targets. Results from this program are discussed earlier in this press
release.
Diamond Drilling
:
Drilling in 2024 discovered two areas of porphyry-style copper-gold mineralization
at Berezski Central and Berezski North, and the discovery of wide zones of gold mineralization at
Berezski East.
Drilling commenced in
May 2025
with a second drill-rig added in June, to focus on exploring the
principal targets and better understand their controls on mineralization and size potential. In addition,
several holes were drilled to explore regional geochemical and geophysical targets.

Berezski Central Results
: Drilling continues to expand the footprint of the porphyry Cu-Au
mineralization to approximately
600 m
x
500 m
. Drilling has also confirmed that mineralization
extends to at least
600 m
depth, showing that there is a robust porphyry system at this target.
Berezski East Results
: Drillhole EL25019 delivered an exceptional high-grade gold-copper intercept
from surface at Berezski East. The hole intersected broad zones of potassic alteration and the
presence of copper minerals such as bornite and chalcopyrite suggests this target, originally thought
to be related to an epithermal system, may form part of a larger porphyry system. The KGK drilling
appears to have expanded the footprint of the Berezski East mineralization to at least a
1000 m
strike length, a highly encouraging development.
Berezski North Results
: Drilling at Berezski North continues to demonstrate the presence of a
large porphyry system at Berezski North. Drilling has defined a
600 m
NW-SE trending zone at
Berezski North that remains open in the northwest and southeast directions and at depth. Hole
EL25016, approximately
300 m
southeast of Hole EL24005 intersected thick zones of high-grade
copper-gold mineralization from surface, and drill-holes EL25014A and EL25027 (results pending)
intersected thick zones of high-grade mineralized breccias in the former, and zones of porphyry-style
mineralization in the latter, demonstrating that we're vectoring towards the core of the system.
Drilling & Assays Pending
: The drilling program will pause for approximately six weeks over the
holiday period with the drill rigs undergoing planned maintenance and are expected to restart in
February. Assay turnarounds incurred a four-week export delay to the ALS analytical lab in
Ireland
due to a Kazakh Customs IT system fault in November. This was rectified in early December and
normal timing for shipments has resumed. At present, samples from 6 holes are currently in the lab
waiting analysis. The Company expects to receive the assay results from these holes in
January/February.
Aimandai Trend:
A Vector IP and IP survey was conducted over the Aimandai Trend, a 14 km
copper-in-soil anomaly located approximately 7 km east of the Berezski Trend. This was followed by
an 18.5-square km MT and Gravity survey targeting priority areas of the Trend. Data analysis and
final results are expected by year-end and the Company will be evaluating and ranking exploration
targets at this target area in the New Year.
Stepnoe & Ekidos Projects
The Stepnoe and Ekidos licenses cover early Ordovician aged rocks of the lower Boshchekul-
Chingiz volcanic arc that hosts the Beskauga Deposit. The licenses are covered by a 10-
50m
thick
cover sequence of soil and lacustrine sediments. The Company completed a large top of bedrock
(KGK) drill program (659 holes totaling 20,099 meters) in
October 2025
.
The KGK drilling showed that the geology of the Stepnoe-Ekidos area is mostly composed of fine-
grained weakly magnetic tuffs, highly magnetic crystal tuffs, lithic tuffs and andesites. Sedimentary
rocks are present, dominated by siltstones. The drilling also identified multiple dioritic intrusions
cutting through this andesite-volcano-sedimentary sequences.
Figure 8: Geology of the Stepnoe-Ekidos Licenses (CNW Group/Arras Minerals Corp.)
The assay results from the final 22 holes are still pending. However, the Company believes that the
drilling has identified path-finder geochemistry and alteration signatures related to 2-3 discrete
porphyry systems in the license areas.
