Ongoing Drilling of Kiena Deep a Zone Confirms Multiple High Grade Lenses

and Extends Zone Down Dip

TORONTO, May 17, 2018 -- Wesdome Gold Mines Ltd. (TSX:WDO) (“Wesdome” or the “Company”) is pleased to provide the

results from the ongoing underground drilling of the Kiena Deep A Zone completed from the exploration ramp at its 100%

owned Kiena Mine Complex, in Val d'Or, Quebec.

Development of the Kiena Deep exploration ramp and associated drilling platforms from the 1000 metre level was recently

completed and drilling of the Kiena Deep A Zone is ongoing with three drill rigs. The initial drilling of 7 holes returned a number

of encouraging intersections, including 39.6 g/t Au over 18.2 m core length (12.6 g/t cut, 10.4 m true width) in hole 6275 (See

news release dated April 24, 2018). Drilling is ongoing and to date a total of twenty holes totaling approximately 6,850 metres

have been completed into the A Zone.

Results Highlights:

Kiena Deep A Zone

• Hole 6295: 9.9 g/t Au over 8.9 m core length (6.2 g/t cut, 6.4 m true width)

• Hole 6296: 43.3 g/t Au over 6.5 m core length (6.8 g/t cut, 5.5 m true width)

• Hole 6290 - Zone A: 28.8 g/t Au over 3.2 m core length (10.5 g/t cut, 2.7 m true width)

• Hole 6290 - Zone A1: 26.0 g/t Au over 25.7 m core length (7.3 g/t cut, 20 m true width)

• Hole 6299 – Zone A1: 29.6 g/t Au over 10.2 m core length (9.8 g/t cut, 7.7 m true width)

• Hole 6299 – Zone A2: 77.4 g/t Au over 14.4 m core length (12.8 g/t cut, 10.8 m true width

All assays cut to 34.28 g/t Au. True widths are estimated.

Mr. Duncan Middlemiss, President and CEO, commented “Assay results of Kiena Deep Zone A continue to return high grade

results and further confirm continuity in this area. We are particularly excited that the drilling has extended the known

mineralization at least 50 metres down plunge, and confirms the presence of three high grade lenses. This hole may represent

a new style of mineralization at Kiena Deep and it indicates the potential for discovering additional mineralization in this wider

and higher grade geologic horizon, that remains open down plunge and down dip.  We plan to drill a twin hole in the near term

to test this highly prospective area of the Kiena Deep deposit, and test for additional lenses within the A Zone. Additionally we

have just moved a drill to a new platform which will concentrate on the Upper Quartz Vein Zone interpreted to be located above

the ramp elevation. A fourth drill rig continues to test the VC Zone and S-50 Extension Zone auxiliary targets. Our goal

remains to continue to better define the extent and geometry of gold mineralization in these areas in advance of an updated

resource estimate by the end of the year.”

Drilling continues to trace the Kiena Deep mineralized system along an altered and deformed north-northwest trending

("NNW") basalt-komatiite contact zone in order to better define the known mineralization and possible extensions, and also to

identify new zones. Visible gold was observed in majority of the drill holes within predominantly shear zone hosted quartz

veins. The drilling has confirmed the continuity of the mineralized zones, and one hole has extended the known mineralization

at least 50 metres down plunge in an area that was previously thought to be truncated at the mafic-ultramafic contact. The dip

of the contact is now interpreted to flatten to the east and provides additional potential for down plunge mineralization as

mineralizing fluids pooled against the mafic-ultramafic contact. This drilling, intersected alteration, veining and gold

mineralization over a down hole length of over 100 metres and is host to three main mineralized zones. Additionally, the

degree of alteration in this hole is amphibolite, which may represent a higher degree of metamorphic grade than previously

identified. It is interpreted that these potentially different mineralizing fluids contributed to the higher grades being encountered

in multiple zones. This area remains open down plunge and remains a focus for ongoing drilling. The results are highlighted

below and summarized in Table 1 and illustrated in Figures 1, 1b and 2.

With completion of the ramp development and drilling platforms, drilling has commenced to test the Upper Quartz Zone, where

previous drilling encountered an intercept of 94.4 g/t Au ( 18.03 g/t Au cut) over 17.4 m core length (See news releases dated

August 24, 2016).

In addition, one drill continues to follow up on near-mine, auxiliary targets including the VC and S-50 Zones, as they are

important components of any potential re-start plan since they are located close to existing mine infrastructure and

development. Cross-cut development on the 670 metre level has commenced and is scheduled to be completed in June 2018

to provide drilling platforms to test the VC1 and VC6 zones.

THE KIENA COMPLEX

The Kiena Mine Complex is a fully permitted, integrated mining and milling infrastructure which includes a 930 metre

production shaft and 2,000 tonne per day capacity mill. From 1981 to 2013 the mine produced 1.75 million ounces of gold from

12.5 million tonnes at a grade of 4.5 g/t. The bulk of this production came from the S-50 Zone between depths of 100 and

1,000 metres. In 2013, operations were suspended due to a combination of declining gold prices and lack of developed

reserves. The infrastructure has been well preserved on care and maintenance status. An independent 43-101 report dated

December 16, 2015 for the first time assessed the exploration potential and known resources for the entire property. Measured

and Indicated resources below a 100 metre crown pillar total 2,500,600 tonnes at 5.59 grams per tonne for 449,000 ounces.

Additional inferred resources below a 100 metre crown pillar total 1,563,300 tonnes at a 7.97 grams per tonne for 400,400

ounces.
