Wesdome Drilling Confirms Continuity of Presqu’Île Zone and Prepares FOR Exploration RAMP Development at Kiena MINE

Exploration Programs

WESDOME DRILLING CONFIRMS CONTINUITY OF PRESQU’ÎLE ZONE AND PREPARES FOR

EXPLORATION RAMP DEVELOPMENT AT KIENA MINE

Toronto, Ontario – September 19, 2023 – Wesdome Gold Mines Ltd. (TSX: WDO) (“Wesdome” or the “Company”) today

announces the 2023 surface exploration drilling results from the Presqu’île Zone located 1.3 km north-west of the

Company’s 100% owned Kiena Mine Complex in Val d'Or, Quebec.

Recent drilling at Presqu’île is part of an ongoing exploration program focussing on near surface gold potential along strike

from Kiena that remains under explored. Drilling results from the Shawkey and Dubuisson Zones, located further to the

east along strike, were released earlier this year (see May 23, 2023 release, “Wesdome Drilling Southeast of Kiena Mine

Identifies Potential Bulk Tonnage Underground Target; Returning 2.3 g/t Gold Over 72 m Core Length”). Ongoing drilling

highlights the potential of this area to add to the existing resource base proximal to mine infrastructure and remains a

priority for the Company (Figure 1).

Highlights of recent in-fill drilling are listed below and are summarized in Table 1. Assay results for nine (9) of thirty-two

(32) diamond drill holes planned are pending.

• Hole PR-23-070: 32.5 g/t over 3.0 m core length (30.0 g/t Au capped*, 2.9 true width) PR-2A Zone.

• Hole PR-23-084 : 14.0 g/t Au over 5.3 m core length (14.0 g/t Au capped*, 4.0 m true width) PR-2 Zone.

• Hole PR-23-058A : 9.31 g/t Au over 4.6 m core length (9.31 g/t Au capped*, 4.3 m true width) PR-2 Zone.

* All assays capped at 90 g/t. Au. True widths are estimated based on 3D model construction.

Ms. Anthea Bath, President and CEO commented, “We are pleased with the recent surface d rill results that confirm

continuity of mineralization at Presqu’île. The Presqu’île Zone is just one of several zones having the potential to offer a

supplementary source of mill feed near-surface or in the upper mine area for the underutilized Kiena mill. Recent drilling

results from the Shawkey and Dubuisson Zones, both adjacent to the existing 33-level track drift development that extends

over three kilometres east of the Kiena mine shaft, further reinforces the potential of this area. As our exploratio n

continues and the refinement of the geologic model increases, we are confident we will identify more zones of gold

mineralization accessible from 33 level, as well as additional down plunge extensions similar to the Kiena Deep Zone.

Recent drilling supports the decision to proceed with the exploration ramp from surface later this year to further assess

the continuity of the mineralization and test the down plunge extension of the deposit. The excavation of the ramp is

expected to proceed in Q4 2023 once required permits are secured. This ramp can also be integrated with Kiena's existing

underground ramp network, providing additional access to surface for ongoing operations and future mining of deposits

such as Dubuisson from 33 level further to the east.”

Since 2020, drilling at Presqu’île has identified five gold -rich zones crosscutting mafic rocks (Zones PR-1, 2 and 2A) and

ultramafic rocks (Zones PR-3 and 4). PR-1 and PR-2A are parallel to each other trending east-west and dipping north, while

PR-2 strikes southeast-northwest and crosscut the east -west zones. Gold mineralization is associated with traces to 5%

disseminated sulphides (pyrite, pyrrhotite, chalcopyrite, sphalerite and galena) and local gold grains occurring in quartz -

chlorite-carbonate or quartz (grey) vein contacts as well as in moderately to strongly chloritized and biotitized host rocks.

The 2023 surface drilling program, which is expected to be completed by the end of September, was designed to increase

the size and confidence in the mineral resources for Zones PR-1, 2 and 2A (Figure 2). The 2023 drilling program confirmed

not only the continuity of the gold mineralization at Presqu’île and the validity of the geologic model, but also the potential

for down plunge extensions toward east of Zones PR-2 and PR -2A. Both zones are interpreted as excellent target for a

follow up drilling program from surface or from underground with development of an exploration ramp.

Presqu’île has a mineral resource estimation of 138,000 tonnes grading 8.2 g/t Au totalling 37,000 oz as Indicated Mineral

Resources and Inferred Mineral Resource of 202,000 tonnes grading 7.4 g/t and totalling 48,000 oz of gold from the three

lenses (PR-1, PR-2, and PR-2A Zones) as of December 31, 2022.

TECHNICAL DISCLOSURE

The technical and geoscientific content of this release has been compiled and reviewed by Denys Vermette, P. Geo.,

(OGQ #564) Exploration Manager of the Company, and a "Qualified Person" as defined in National Instrument 43-101 -

Standards of Disclosure for Mineral Projects.

Sample preparation and analytical work was performed by ALS Minerals of Winnipeg (Manitoba), a certified commercial

laboratory (Accredited Lab #689). Assaying comprised fire assay methods with an atomic absorption finish. Any sample

assaying >3 g/t Au was rerun by fire assay method with gravimetric finish, and any sample assaying >10 g/t Au was rerun

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.
