TORONTO, ON–(Marketwired – June 21, 2017) – Wesdome Gold Mines Ltd. (TSX: WDO) (“Wesdome” or the “Company”) is pleased to provide an update on underground drilling activities and upcoming exploration ramp development at its 100% owned Kiena Mine Complex, in Val d’Or, Quebec.

On May 3, 2017, Wesdome announced plans to drive an exploration ramp to provide enhanced drill coverage of the Kiena Deep discovery, which remains open at depth and along strike. The ramp is scheduled to commence in August and take 9 – 10 months to complete (see Figures 1, 2 and 3). The company has received bids from six qualified contractors with the aim to award the ramp development work by July 1^st. As it currently stands, the Kiena Deep target cannot be traced further efficiently from existing workings. The Company expects to have initial new drill stations available to restart Kiena Deep drilling as early as September – October, 2017, concurrent with ramp development activities.

The present drill program encompasses 2 drills tracing auxiliary targets, which are close to existing workings, open at depth, and demonstrate near-term development potential (see Figures 4, 5 and 6).

Mr. Duncan Middlemiss, President and CEO, commented “The two drills currently underground at Kiena will focus on drilling other prospective targets including the VC and S50 Zones, which are located close to existing infrastructure. The current pause on the Kiena Deep exploration gives the Company ample opportunity to further delineate existing resources which could potentially aid in a recommencement of production in the short to mid-term. Kiena has a strong resource base from which to work, with measured and indicated resources of 2.5M tonnes @ 5.59 g/t Au for 449,300 ounces contained and inferred resources of 1.6M tonnes @ 7.97 g/t Au for 400,400 ounces contained. It is a large property with three former producing mines and eight shafts located within. We believe the Kiena Deep Zone may be the anchor which establishes future production and allows for a thorough examination of this high potential property.”

RECENT KIENA DEEP DRILLING RESULTS (Table 1)

Recently received results support a north extension of the Kiena Deep A Zone proximal to the basalt-komatiite contact (Figures 1 and 3). Highlights include:

Kiena Deep – Open to North (Figure 1)

• 12.81 g/t uncut over 8.8 m core length (8.38 g/t cut) in hole 6166
• 5.19 g/t uncut over 14.3 m core length (5.19 g/t cut) in hole 6179,

Including 11.38 g/t over 5.2 m uncut (11.38 g/t cut)

Assays are cut to an arbitrary 34.28 g/t and true widths are currently undetermined

AUXILIARY TARGETS

The Company is currently drilling the VC Zone at depth and the S50 Zone where it is immediately accessible from the 960 m level and the 980 m level. At shallower depths there is identified potential for the S50 southeast lens and the South Zone, which remain open below 330 m level.

1) VC Zone – 670 m to 1100 m levels (Figure 4)

This zone remains open at depth. Previous results include the following highlights (see press release dated June 13, 2012):

• 5.41 g/t uncut over 10.6 m true width (5.41 g/t cut) in hole U4539
• 7.18 g/t uncut over 10.3 m true width (7.13 g/t cut) in hole U5813

Partial assay results have been received from our first hole drilled in 2017.

• 8.23 g/t over 5.3 m uncut (8.23 g/t cut) in hole 6192

2) S50 Zone – immediately accessible target 960 m – 1100 m level (Figure 6)

Preliminary results include:

• 5.00 g/t over 11.7 m uncut (5.00 g/t cut) in hole 6145A
• 3.89 g/t over 8.0 m uncut (3.89 g/t cut) in hole 6147
• 4.12 g/t over 14.8 m uncut (3.50 g/t cut) in hole 6165
• 5.92 g/t over 7.0 m uncut (5.92 g/t cut) in hole 6168
• 10.34 g/t over 9.2 m uncut (8.13 g/t cut) in hole 6188

3) S50 Southeast Lens – open below 330 m level (Figure 5)

Highlights include:

• 6.80 g/t uncut over 18.5 m core length (6.80 g/t cut) in hole U4115
• 4.91 g/t uncut over 16.6 m core length (4.91 g/t cut) in hole U4117

4) South Zone – open below 330 m level (Figure 5)

Previous limited drilling returned the following highlights (press-release dated January 2, 2013)

• 21.07 g/t uncut over 7.5 m core length (8.60 g/t cut) in hole U5454
• 10.59 g/t uncut over 5.1 m core length (8.86 g/t cut) in hole U5445
• 11.40 g/t uncut over 3.5 m core length (11.40 g/t cut) in hole U5411

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.
