WESDOME INTERSECTS 7.8 G/T GOLD OVER 57.2 METRES AT KIENA DEEP,
CONFIRMING THE NORBENITE FOOTWALL ZONE; DISCOVERS A NEW ZONE NEAR
INFRASTRUCTURE
Toronto, Ontario – September 10, 2026 – Wesdome Gold Mines Ltd. (TSX:WDO , OTCQX:WDOFF) (“Wesdome” or
the “Company”) today provides an update on its exploration drilling activities at its wholly-owned Kiena mine (“Kiena”)
near Val-d’Or, Quebec (Figure 1).
HIGHLIGHTS (Figures 2 and 3)
Norbenite Footwall Zone Confirmed (Figures 4 and 5, Table 1) 1
• A third broad intercept solidifies the recently announced discovery of the Norbenite Footwall Zone.
o N134-7207: 7.8 g/t Au uncapped over 57.2 m core length, (7.4 g/t Au capped, 57.2 m core length).
• Together with two prior holes – hole N134-7152W1 that intersected 6.9 g/t Au uncapped over 42.1 metres and
historic hole 6752W10 that intersected 9.9 g/t Au over 83.2 metres – the Norbenite Footwall Zone now traces over
150 metres vertically with significant thickness and grade.
• Drilling at depth continues to delineate the new Norbenite Footwall Zone beyond the Norbenite Fault where
mineralization has been traced over at least 150 vertical metres in basaltic rock and remains open up -plunge,
laterally, and at depth, highlighting significant growth potential.
VZ Zone and VZ Parallel Vein Discovery (Figure 6, Table 1)1
• The new VZ Zone opens a previously untested parallel trend less than 100 metres from existing infrastructure, with
six holes confirming continuity.
• One exploration hole intersected a new parallel mineralized vein adjacent to the VZ Zone and less than 50 metres
from existing infrastructure.
o N109-7213: 23.8 g/t Au uncapped over 4.0 m core length (23.8 g/t Au capped, 4.0 m core length)

1Assays capped at 90 g/t for Kiena Deep zones (assays capped).
Anthea Bath, President and Chief Executive Officer, commented, "These latest positive results are meaningfully shifting
how we think about the potential scale of Kiena Deep. The results provide growing evidence that the area hosts multiple
recurring high-grade structures beyond the mineralized zones currently included in our resource model. However, the
full extent and ultimate scale of the mineralized system remain to be determined.
“Further growth of these zones has the potential to increase ounces per vertical metre, create new mining areas, and
substantially change how we view the future scale and configuration of the mine.”

Jono Lawrence, Senior Vice President, Exploration and Resources, added, “At the Norbenite Footwall Zone, hole N134-
7207 is our third broad high-grade intercept beyond the Norbenite Fault. Together, there are three holes that now trace
mineralization over 1 50 vertical metres. The zone remains open laterally, at depth, and most importantly up -plunge
across at least 300 vertical metres of largely untested ground toward the upper Footwall Zone and potentially beyond.
The new level 134 exploration drive gives us the platform to test this opportunity systematically, and if scale and continuity
is established, the Norbenite Footwall Zone could become a material contributor to the future of the mine.
“Separately, drilling at level 109 has confirmed the emerging VZ Zone and identified an additional high -grade parallel
vein in close proximity to existing infrastructure. These are distinct exploration opportunities that together support our
interpretation of a broader system containing multiple high-grade lenses, many of which remain insufficiently tested.
“The balance of this year ’s program will focus on defining the geometry and continuity of these two high-grade, near-
infrastructure opportunities, with results informing our next mineral resource update.”
TECHNICAL DETAILS
Norbenite Footwall
Hole N134-7207, drilled from the level 134 exploration drive, returned a broad, high -grade intercept of 7. 8 g/t Au over
57.2 metres core length, hosted within a quartz vein system in basaltic rock. Together, with hole N134 -7152W1, which
intersected 6.9 g/t Au over 42.1 metres core length and historic hole 6752W10 , which intersected 9.9 g/t Au over 83.2
metres core length (refer to news release dated June 22, 2026), these results support the potential for resource growth
from the newly identified Norbenite Footwall Zone, adjacent to the Norbenite Fault.
Hole N134-7207 was designed to test the area between hole N134-7152W1 and the historic 6752W10 drill hole, with the
objective of evaluating the continuity of the basalt host rock and associated mineralization. The basaltic host rock offers
strong ground co mpetency that supports efficient and stable mining operations. Results from hole N134 -7207 provide
additional evidence of continuity, and capacity for high-grade mineralization growth.
Additional drilling will be required to fully define the geometry and extent of the zone, which is now interpreted to continue
over a 150-metre vertical profile . At least 300 vertical metres of ground between hole N134 -7152W1 – the uppermost
intercept of the Norbenite Footwall Zone – and the upper levels of existing Footwall Zone mineralization remain largely
untested. Confirming continuity of the Norbenite Footwall Zone mineralization to the Footwall Zone levels would validate
the geologic model and potentially pave the way for testing further extension to the upper levels of the mine. Previous
holes terminated within the Norbenite Fault structure, leaving this prospective corridor open for systematic drilling.
VZ Zone
Exploration drilling has confirmed the discovery of the VZ Zone, located less than 100 metres from the existing drill bay
on level 109. An initial hole drilled in 2025, N109 -7017, returned encouraging results, though at the time it was unclear
whether this intercept represented an isolated occurrence or a distinct mineralized zone. Five additional holes reported
in this release , including N109-7204, N109 -7205A, N109 -7206, N109 -7213, and N109-7214, have confirmed the
continuity of this mineralized lens, establishing the VZ Zone as a new near-mine zone and opening a previously untested
trend at shallow depths of the mine. The proximity of these intercepts to existing mine infrastructure highlights the ir
potential for future mine planning. With limited drilling completed along this trend, the results indicate significant potential
for resource growth, and aggressive follow-up drilling is planned as initial results have exceeded expectations.
The discovery of the VZ Zone, located near the VC Zone (Figure 2), is particularly significant as both zones occur at
relatively shallow levels and could be accessed through future infrastructure development. The potential to develop both
zones within a common mining area could provide an opportunity to increase ounces per vertical metre and improve the
overall efficiency of future mine development.

Located approximately 300 metres to the west, the VZ Zone sits within a deformation corridor that links back to the ZA
lenses of Kiena Deep (Figure 3). With high-grade lenses at Kiena Deep open along strike toward VZ Zone, drilling this
westward trending corridor is a priority focus, particularly as it remains untested at key mine elevations. This
demonstrates the strong potential of near-mine exploration to identify new mineralized systems, expand Kiena’s mineral
inventory, and support future mine development.
VZ Parallel Vein
Recent exploration drilling near-mine from level 109 has identified a new high-grade vein of mineralization where drill
hole N109-7213 intersected 23.8 g/t Au uncapped over 4.0 metres core length. This new vein is hosted within the same
basaltic unit as the VZ Zone and is located between the current drill bay and the VZ Zone, approximately 50 metres from
the drill bay. The vein remains open up-dip and laterally, and additional drilling is underway to continue defining the full
extent and opportunity.

TECHNICAL DISCLOSURE
Exploration Kiena drilling, the drill core NQ in size, was cut in half with a diamond saw resulting in a half core sample for
assay and a half core sample to be retained for reference. Delineation drilling, in defined resource areas, is BQ in size
and the entire core was sent for assay analysis. Analytical work is performed by ALS Minerals of Val -d’Or (Québec), a
certified commercial laboratory (Accredited Lab #689). Sample preparation was completed at ALS Minerals in Val -d'Or
(Québec). Assaying comprised fire assay methods with an atomic absorption finish. Any sample assaying >3 g/t Au was
re-run using the fire assay method with gravimetric finish, and for any sample assaying >10 g/t Au was re -run with the
metallic sieve method. In addition to laboratory internal duplicates, standards, and blanks, the geology department inserts
blind duplicates, standards, and blanks into the sample stream at a frequency of one in twenty to monitor quality control.
The QP confirmed the disclosed data, including the underlying sampling, Reports from Lab Results and there was
validation on the QAQC process and reports from ALS results received. A visual observation of historical core was done
in person at site along with approval of the procedures for drill hole description s, sampling and preparation of samples
prior to being shipped to the ALS Lab. Verification and validation of assay results highlighted that all QAQC sample
results were within respective control limits.
