WESDOME EXPLORATION DRILLING CONTINUES TO EXPAND

HIGH GRADE 300 EAST ZONE DOWN PLUNGE AT THE EAGLE

RIVER MINE RETURNING 40.7 GRAMS PER TONNE GOLD CUT OVER

6.0 METRES TRUE WIDTH

Toronto, Ontario – June 14 2023 – Wesdome Gold Mines Ltd. (TSX: WDO) (“Wesdome” or the

“Company”) today announces results from the ongoing underground exploration drilling program at

the Company’s wholly-owned Eagle River Mine in Wawa, Ontario.

Ongoing extension and definition drilling of the 300 East Zone has continued to confirm the

continuity of the geometry and the consistency of the high-grade mineralization down plunge. The

300 East Zone, previously defined from the 750 m-level to 1,400 m-level, has now been extended to

the 1,600 m-level and remains open down plunge (Figure 1). The width of the quartz veining is

typically less than 1.5 metres true width; however, recent drilling along the eastern margin of the 300

East Zone has returned wider widths. This occurs in an area that is interpreted to be at the

intersection of several structures having different orientations and/or folding resulting in wider

zones of gold mineralization. These wider widths and more complex geometry are similar to that of

the previously mined 303 Lens located approximately 400 m up plunge from this area, which was

mostly mined in 2019.

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

• Hole 925-E-231: 77.6 g/t Au over 9.4 m core length (40.7 g/t Au cut, 6.0 m true width)

o Including 225.1 g/t Au over 3.0 m core length

• Hole 925-E-233: 42.6 g/t Au over 4.9 m core length (42.3 g/t Au cut, 1.7 m true width)

o Including 62.8 g/t Au over 3.3 m core length

• Hole 771-E-33: 150.7 g/t Au over 2.8 m core length (51.7 g/t Au cut, 1.6 m true width)

o Including 497.8 g/t Au over 0.7 m core length

All assays cut to 140.0 g/t Au. True widths are estimated.

Warwick Morley-Jepson, Board Chair and Interim CEO commented, “These results continue to

confirm the geometry and high grades of the 300 East Zone. The objective of drilling this zone is to

define a second, higher-grade lens similar to the previously mined 303 Lens that could potentially

positively impact gold production. The 303 Lens was mined primarily in 2019 and average muck

grade was 46.1 g/t.

Additionally, the drilling of the 300 East Zone confirms the continuity of the mineralization at

depth, thus suggesting that many other similar zones, such as 808, 811, 818, 711 and 7 East, have

this same potential to continue at depth.

Elsewhere at Eagle River, the Company is following up on multiple encouraging drill intersections

last year both west of and along strike of, and subparallel to the Falcon 7 zone, including the western

extension of the 311 West and 5 zones in the volcanic rocks. Any resources discovered in this area

could meaningfully enhance the future operational flexibility of the asset.

Meanwhile, we remain focused in 2023 on converting a large, inferred base into indicated and

measured resources and subsequently reserves.”

TECHNICAL DISCLOSURE AND QA/QC

The sampling of, and assay data, from drill core is monitored through the implementation of a

quality assurance - quality control (QA-QC) program designed to follow industry best practice.

Underground drill samples are transported in sealed bags to the Eagle River Mine assay office in

Wawa, Ontario. Samples are analyzed for gold using standard fire assay technique with gravimetric

finish. Wesdome inserts blanks and certified reference standards into the sample sequence for

quality control at the laboratory. The QA/QC procedure is described in more detail in the 2022

Technical Report filed on SEDAR on April 22, 2022.

The technical content of this release has been compiled, reviewed, and approved by Aliou Sene,

P.Geo., Chief Mine Geologist at Eagle River Complex of the Company a "Qualified Person" as

defined in National Instrument 43-101 -Standards of Disclosure for Mineral Projects.
