WESDOME DRILLING CONFIRMS CONTINUITY OF PRESQU’îLE

ZONE AND IS INVESTIGATING INSTALLATION OF EXPLORATION

RAMP FROM SURFACE ADJACENT TO THE KIENA MINE

Toronto, Ontario – September 8, 2022 – Wesdome Gold Mines Ltd. (TSX: WDO) (“Wesdome” or

the “Company”) today announces surface exploration drilling results from the Presqu’île Zone at the

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

Since the completion of the PFS for the Kiena Mine in 2021, both surface and underground drilling

has been more focused on exploration targets proximal to the Kiena Mine. Initially this drilling has

been completed along strike f rom the Kiena Mine within the prospective Jacola Formation in o rder

to provide additional feed for the Kiena mill. Most r ecently surface drilling has focused on the

Presqu’île Zone located 2 kilometres west of the Kiena Mine (Figure 1). Previous drilling at the

Presqu’île zones has defined a near surface mineral resou rce (Inferred Mineral Resource of 353,000

tonnes grading 7.1 g/t au totalling 80,600 oz of gold from 3 lenses [PR-1, PR-2, and PR-2A zones]

December 31, 2021 Mineral Resources).

Recent drilling has confirmed several narrow, subparallel zones that are steeply east-plunging located

proximal to a sheared mafic-ultramafic contact. The zones are generally hosted by a porphyritic basalt.

The mineralization corresponds to several quartz-carbonate-chlorite veins (<40cm) mineralized with

pyrite, chalcopyrite, sphalerite, galena and ±visible native gold . Quartz veins are associated with a

typical biotite alteration. The drilling has confirmed the continuity of the mineralized zones. The PR-

2A Zone is interpreted to be open along strike eastward and down dip and represents an excellent

target for the exploration drilling at depth.

Highlights of the recent drilling are listed below and are summarized in Table 1.

• Hole PR-22-034: 24.3 g/t over 3.3 m core length (10.6 g/t Au capped*, 3.0 true width) PR-1

Zone

• Hole PR-22-026: 30.0 g/t Au over 9.4 m core length (13.1 g/t Au capped*, 9.2 m true

width) PR-2A Zone

• Hole PR-22-024: 45.0 g/t Au over 3.8 m core length (18.5 g/t Au capped*, 3.7 m true

width) PR-2A Zone

• Hole PR-22-029: 27.6 g/t over 3.5 m core length (12.8 g/t Au capped*, 3.3 m true width)

PR-2 Zone

* All assays capped at 35 g/t. Au. True widths are estimated based on 3D model construction.

Given the significant upside that the Presqu’île zone could represent for Kiena, the Company is

currently evaluating options to fast-track an exploration ramp from surface. This infrastructure would

provide the ideal platform for exploration activities to test the potential of the Presqu’île area. It could

also easily be connected to Kiena’s existing underground ramp network, providing access to surface

for the existing operation. This could represent a significant milestone on the Company’s journey to

unlock the full potential of Kiena, as it would provide a second access for conveyance of material and

personnel, freeing time for additional ore hoisting via the shaft. Other gains, such as reduced

ventilation costs and savings from added operational flexibility are also expected.

Mr. Duncan Middlemiss, President and CEO commented, “We are pleased with the recent surface

exploration results at Presqu’île which could potentially increase our resource base in areas proximal

to the mine. The Presqu’ île Zone repr esents an opportunity to establish an exploration ramp for

further exploration of the zone but also to provide a ccess to the underground workings via a ramp

system that would greatly improve efficiencies at the Kiena mine.

We are currently drilling with t wo drills on barges and one surface drill to explore adjacent

mineralization to the Kiena mine within the Jacola Formation. Several of these areas include the

Dubuisson, Shawkey, Thompson, and recently discovered Bourgo zone again having the potential to

add to feed for the Kiena mill. Drilling is ongoing and updates will be released within the next several

months. It is evident that as we continue to explore and collect new geological information, we are

able to discover traps for gold mineralization, thereby demonstrating the prospectivity of the property.

We are also pleased with the progress being made at the construction of the paste back fill plant that

is expected to be completed in November. As part of this, the most critical components of the paste

fill plant, the motor control system (MCC ) have been received and being installed. Commissioning

remains on track for Q4 2022.”

TECHNICAL DISCLOSURE

The technical and geoscientific content of this release has been compiled and reviewed by Denys

Vermette, P. Geo., (OGQ #564) Consultant Geologist for IOS Services Géoscientifiques from

Chicoutimi, Qc), and approved by Bruno Turcotte, P.Geo., (OGQ #453) Chief Geologist –

Underground Exploration of the Company, both "Qualified Persons" as defined in National

Instrument 43-101 -Standards of Disclosure for Mineral Projects.

Analytical work was performed by ALS Minerals of Val -d’Or (Quebec), a certified commercial

laboratory (Accredited Lab #689). Sample preparation was completed at ALS Minerals in Lachine

(Quebec). Assaying comprised fire assay methods with an atomic absorpt ion 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 geolo gy department inserts blind duplicates, standards, and

blanks into the sample stream at a frequency of one in twenty to monitor quality control.

COVID-19

The health and safety of our employees, contractors, vendors, and consultants is the Company’s top

priority. In response to the COVID -19 outbreak, Wesdome has adopted all public health guidelines

regarding safety measures and protocols at all of its mine operations and corporate office. These

protocols are still in place at all sites despite the loosening of some provincial public health guidelines.

In addition, our internal COVID -19 Taskforce continues to monitor developments and implement

policies and programs intended to protect those who are engaged in business with the Company.

Through care and p lanning, to date the Company has successfully maintained operations; however,

there can be no assurance that this will continue despite the Company’s best efforts, with the

emergence of new, highly contagious variants such as Omicron. To date, the Company has been

impacted by this most recent variant outbreak, with employees at both operations and corporate office

becoming infected, which may negatively impact our ability to maintain projected timelines and

objectives. Consequently, the Company’s actual future production and production guidance is subject

to higher levels of risk than usual. The Company is continuing to monitor the situation closely and

will provide updates as they become available.
