WESDOME CONTINUES TO DEFINE KIENA HIGH GRADE ZONES

NEAR UNDERGROUND INFRASTRUCTURE AND AT SURFACE

Toronto, Ontario – September 29, 2021 – Wesdome Gold Mines Ltd. (TSX: WDO) (“Wesdome”

or the “Company”) today announces underground exploration drilling results from the Kiena Deep

Zone and initial surface exploration drilling results at the Company’s 100% owned Kiena Mine

Complex in Val d'Or, Quebec.

Kiena Deep A Zone and Footwall Zone Drilling

On March 23, 2021, Wesdome announced the discovery of a new high grade gold zone in the footwall

of the A Zone , (the Footwall Zone ), which has been the focus of our in-fill drilling over the past

several months.

The Footwall Zone is interpreted as lenses of gold mineralization located within a 50 metre (‘m’) wide

corridor adjacent to th e footwall of the A2 Zone. Gold mineralization is associated with quartz ±

visible gold veins that are spatially associated with amphibolite altered komatiite, basaltic komatiite

and basalt units.

Because the recent drilling has been impacted by the industry wide shortage of skilled drillers, 11 holes

and their wedges having reached the Footwall and A Zones since the last press release . As such,

additional drilling is still required to determine the geometry of the mineralized lenses forming the

corridor of the Footwall Zone. The orientation, dip and geometry of these new lenses will need to be

confirmed in order to determine true widths. However, it is interpreted that the Footwall zone runs

parallel to the A Zone and extends at least 300 m. Mineralization remains open laterally and down

plunge (Figure 1).

Additionally, the recent A Zone high grade drill intersections inside and outside of the current A Zone

resource block model shows the potential to expand the current resource estimate.

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

• Hole 6762: 132.1 g/t Au over 7.4 m core length (27.6 g/t Au capped, 3.9 m true width) A

Zone

• Hole 6752W4: 34.3 g/t Au over 7.2 m core length (32.2 g/t Au capped, 3.5 m true width)

A2 Zone

• Hole 6762W2: 13.4 g/t Au over 16.0 m core length (13.0 g/t Au capped) Footwall Zone

• Hole 6762W1: 20.1 g/t Au over 9.1 m core length (18.5 g/t Au capped) Footwall Zone

All assays cut to 90.0 g/t Au. True widths are unknown at this time for the Footwall Zone.

Regional Surface Exploration Drilling

Initial surface drilling has focused on the Presqu’ile and Shawkey areas located northwest and

southeast of the Kiena Mine, respectively (Figure 2). Since July 2021, two drills on barges have been

testing the continuity of some gold anomalies in the Jacola Formation which host the Kiena mine.

In early September 2021, a third drill was added in the Shawkey area to follow up on historical gold

anomalies and newly intersected mineralization.

Highlights of the recent drilling at Presqu’ìle and Shawkey zones are listed below and summarized in

Table 2.

• Hole PR-20-001: 1515.0 g/t Au over 0.5 m core length

• Hole PR-20-001: 23.1 g/t Au over 2.2 m core length

• Hole PR-21-008: 63.9 g/t Au over 0.9 m core length

• Hole SW-21-009: 20.80 g/t Au over 1.5 m core length

• Hole SW-21-013: 29.40 g/t Au over 1.1 m core length

The true widths of the intersections of the Presqu’ìle zones are believed to be of 70% or higher of the

intersected length.

Previous drilling at the Presqu’ile zones has defined a small near surface mineral resource (see press

release dated December 15th, 2020). Eleven of the reported holes for this zone intersected gold

mineralization and helped to define a steeply east-plunging trend. Future drilling will continue to test

the extent of the mineralization which is near to an underground access at a vertical depth of 320 m

below surface and approximately 450 m to the north.

The drilling in the Shawkey area was following up on gold anomalies in historical holes and

exploring untested areas along strike. Eight holes intersected a new zone called Bourgo which is

perpendicular to the general northwest-southeast trend. It consists of quartz veins with very low

sulphide content hosted in a komatiitic basalt unit. The northern orientation is similar to the

orientation of the nearby Kiena Deep A Zones. Drilling is planned to improve the understanding of

this area.

Mr. Duncan Middlemiss, President and CEO commented, “ We are please d with the recent

underground exploration drilling that continues to define the high grade Footwall Zone, which already

extends over 300 metres down plunge. This new discovery could have major positive impacts on the

project as the underground infrastructure utilized to access the A Zones would only incrementally be

added to for the potential mining of the Footwall Zones . It is our goal to include this zone in the

updated mineral resource estimate at year end.

We are also pleased with initial surface exploration results which could potentially increase our

resource base in areas proximal to the mine. These results also illustrate the excellent potential to

find new discoveries on our large, and hugely underexplored property. The fact we have

mineralization in a similar orientation as the A Zones in the Bourgo Zone is notable. Any near mine

resource has the potential to add additional mill feed and place less strain with increased flexibility

on mine production.

Drilling has been impacted by a very competitive market, and we are working with our drilling

contractors to mitigate the shortage of drillers in the area and hope to increase drilling rates going

forward.

We are also please d with the progress being made ramping up production at Kiena. The f irst stope

from the Kiena Deep A Zone is now in production as per plan and will be processed soon at the

Kiena mill, which has been processing ore from the S -50 zone since mid -July. We are satisfied with

the advancement of the project so far and will provide updates accordingly.”

(Quebec). Assaying was done by 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.

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 offices. 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 planning, to dat e the Company has successfully maintained operations, however

there can be no assurance that this will continue despite our best efforts. Future conditions may

warrant reduced or suspended production activities which could 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. We are continuing to closely

monitor the situation and will provide updates as they become available.
