WESDOME ANNOUNCES DRILLING AT THE EAGLE RIVER MINE

DISCOVERS NORTH CONTACT ZONE AND ZONES PARALLEL TO

THE FALCON ZONE

Toronto, Ontario – December 15 2021 – Wesdome Gold Mines Ltd. (TSX: WDO) (“Wesdome”

or the “Company”) today announces the discovery of the North Contact Zone and the discovery of

zones of additional mineralization parallel to the Falcon 7 Zone, at the Company’s wholly-owned

Eagle River Mine near Wawa, Ontario.

North Contact Zone

The North Contact Zone is a new discovery located along the northern contact of the Mine Diorite

and has been intersected by several underground holes that were drilled north of the 300 East zone

to test for parallel structures. The gold mineralization along the northern diorite contact occurs as

visible gold in quartz veins within a shear zone near the 1,000 metre (‘m’) level. Understanding of

the size of this newly identified zone of mineralization will improve with continued drilling that is

ongoing for this area (Figure 1). It is interpreted that the North Contact Zone has been previously

intersected near surface with widely spaced exploration drilling completed on 200 m spaced sections.

This 2016 drilling returned several good intersections in the volcanic rocks adjacent to the mine

diorite, including ERM-2016-27 that returned 32.4 g/t Au over 4.8 m (see press release dated

September 15, 2016). Based on the recent drilling at depth, it demonstrates the potential for gold

mineralization along the north contact extending from the 1,000m level to surface and is within 150

m from mine infrastructure. The strong continuity down plunge is characteristic of the gold

mineralization at Eagle River.

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

• Hole 771-E-23: 9.26 g/t over 1.5 m (true width)

• Hole 771-E-32: 12.19 g/t over 3.7 m (true width)

All assays cut to 125.0 g/t Au. True widths are estimated.

Falcon 7 Zone

The Falcon 7 Zone was discovered in 2019 during surface drilling of the volcanic rocks located

approximately 200 m west of the mine diorite (see press release dated June 6, 2019). Drilling has

been ongoing since the discovery to determine the extent of the zone and to increase confidence of

the gold grade distribution. Recently, underground development has been completed on the 622m

and 635m levels, and long hole stoping from this development has commenced (Figure 2). Sampling

conducted during the development stage and early results from mining confirm high gold grades and

strong mineability. 622m Level chip sampling yielded 54.3 grams of gold per tonne (g/t Au)

(uncapped) and 37.9 g/t Au (capped at 125 g/t Au) over an average thickness of 2.1 m over a

continuous strike length of 75.6 m (See press release dated September 8, 2021).

Falcon 7 Parallel Zones

Recent drilling from the new development intersected several parallel zones to that of the Falcon 7

zone (Figure 3). Although only a limited number of drill holes intersected these mineralized

structures thus far, it does highlight the potential to grow the resource base close to existing

infrastructure. Considering the plunge extent of known zones of mineralization, the Company is

confident that the mineralization in these newly identified zones will display a similar character.

The discovery of these parallel zones shows the potential of the mine diorite and surrounding

volcanics to host more zones of mineralization, especially where host structures continue across the

diorite-volcanic contact, such as 311 West, 8 and 5 zones. Competency differences between the

Mine Diorite and the host volcanic rocks often lead to changes in the host structure’s orientation,

which can facilitate the development of dilational zones, which allow for increased fluid movement

and alteration to occur during metal deposition. Dilational zones can occur to the east and west of

the Mine Diorite and highlight the prospectivity of the volcanic rocks beyond the currently existing

footprint of the Eagle River Mine.

Highlights of the recent drilling are listed below and summarized in Table 2.

• Hole 622-E-49: 13.72 g/t over 1.5 m and 11.2 g/t over 1.5

• Hole 640-E-15: 7.60 g/t over 1.5 m and 11.19 g/t over 2.5 m

• Hole 640-E-11: 5.53 g/t over 1.50 m

• Hole 640-E-12: 13.42 g/t over 1.5 m

Assays capped at 60 g/t Au. True widths are estimated.

In addition, development of the 355m level is proceeding and will provide for development and

exploration of the Falcon 7 zone at higher elevations in the mine and provide a platform to test for

other parallel zones and along strike to the west.

Mr. Duncan Middlemiss, President and CEO commented, "We are pleased with the ongoing

development and mining of the Falcon 7 Zone that brings to Eagle a new, shallow high grade

mining front away from the deeper levels of the mine. This new development has provided drilling

platforms to conduct further exploration, and initial limited drilling has discovered additional parallel

zones having the potential to be of significant size and importance as the Falcon 7 zone is currently.

Development of the 355 m level is proceeding and will provide for development and exploration of

the Falcon 7 zone and other parallel zones at higher elevations in the mine. This is becoming a very

prospective area and could be the next mining area at the Eagle River mine. The 355 m Level

development is extending 400 m west of the mine diorite and will provide platforms to test for gold

mineralization further along strike where surface exploration has returned encouraging results.

Also, the discovery of the North Contact zone, although with limited drilling, represents another

target area for exploration and could be easily accessed from existing mine infrastructure. The

discovery of this zone and recent indications from drilling demonstrates the ongoing prospectivity

of the immediate area of the Eagle River Mine and showcases the quality of this asset. These areas

will continue to be a focus of our exploration efforts going forward.”
