Wallbridge Continues Successful Expansion and Definition of High-Grade Shoots in Tabasco and Area 51 at Fenelon

TORONTO, June 29, 2021 - Wallbridge Mining Company Ltd. (TSX:WM) ("Wallbridge" or the "Company") today announced additional assay results from its current drilling program on the Fenelon Gold Property ("Fenelon" or the "Property"). Expansion drilling continues to reveal additional bulk mineable, near-surface mineralized corridors in the western part of Area 51, while definition drilling continues to define steep, high metal factor (gold grade multiplied by thickness) gold shoots within the Tabasco-Cayenne Zones (see 181-, 134- and 086- shoots on Fig. 1).

Drilling is currently focusing on multiple areas, within the approximately 1.0 km by 1.2 km central portion of the Fenelon Gold System, to expand and better define the mineralization in support of the maiden mineral resource estimate ("MMRE"). Over 200,000 metres of drilling will be incorporated into the MMRE.

Highlight results from these various areas, released today, include:

• Area 51, Near Surface Expansion Drilling:

23.70 g/t Au over 24.90 metres in FA-21-269 (see Figs. 2 and 3);

• Tabasco-Cayenne-Contact Zone, Definition Drilling:
  

6.83 g/t Au over 15.00 metres in FA-21-247 (see Figs. 1, 2 and 6), and
6.61 g/t Au over 11.35 metres in FA-21-261 (see Figs. 1 and 2);

• Area 51, Definition Drilling (near surface down to around 300 m vertical depth - potential open pit resource):
  

1.97 g/t Au over 38.50 metres in FA-21-264A-W1 (see Figs. 2 and 5), and
1.02 g/t Au over 33.70 metres in FA-21-247 (see Figs. 2 and 6);
91.80 g/t Au over 0.50 metres in FA-21-248 (see Figs. 2 and 3);

• Area 51, Definition Drilling (below 300 m depth):
  

15.37 g/t Au over 3.25 metres in FA-21-257 (see Figs. 2 and 3);

"The wide, near-surface intersections in Area 51, consistently yielding 1 to 2 g/t gold average grades, will be very important in building a robust, potentially bulk mineable resource in this part of the deposit. Higher grade intersections, like that intersected in hole FA-21-269, will enhance the larger Area 51 near-surface resource base," stated Marz Kord, President & CEO of Wallbridge.

Marz Kord further added: "The Tabasco intersections in holes FA-21-247 and FA-21-261 released today are important in confirming the presence and geometry of steep gold-rich shoots within the central 600 metre strike length of the Tabasco Zone which has seen the most drilling to date. The ongoing definition drilling and geological modelling has been increasing our understanding of this deposit, as we work towards our maiden resource. It is also revealing the controls on high-grade gold deposition in this gold system and will continue to drive our exploration as we further test the extensions of these zones."

Area 51 Expansion Drill Results

In recent months, drilling has also been focusing on expanding the known footprint of near-surface gold mineralization in the western-southwestern portion of Area 51 in order to grow the open pit resource potential.

Today's results include:

Tabasco-Cayenne-Contact Zones, Definition Drill Results

Definition and expansion drilling at a nominal 75-metre drill spacing, targeting the Tabasco-Cayenne-Contact Zones over a strike length of approximately 800 metres and vertical depths between 300 and 1,000 metres has been the primary focus of this campaign (see Figs. 1 and 2) to better define the geometry and grade of the zones and gain information on the structural controls of the gold mineralization.

Area 51 Definition Drill Results

As our drill holes approach Tabasco-Cayenne, they also transect the Area 51 gold vein network, providing important information from all of these zones.

Near surface highlights from Area 51 zones from the holes reported today include:

Highlight intersections of Area 51 zones from below 300 m vertical depth reported today include:

In-fill Sampling Program Results

A systematic campaign of continuous in-fill sampling of historic drill holes down to a vertical depth of 250 metres is underway in order to collect further information for the open pit constrained portion of the MMRE.

Assay results from the historic drilling in-fill sampling program are highlighted by:

2020-2021 Drilling Program Update

In 2021, the Company is planning to complete approximately 170,000 metres of drilling, approximately 10-15% of which will be devoted to regional exploration on the Company's district-scale, underexplored land package on the Detour-Fenelon Gold Trend.

Assay results of 23 drill holes of the 2021 exploration drill program and one historic drill hole are reported in the Table and Figures below. All figures and a table with drill hole information of recently completed holes are posted on the Company's website under "Current Program" at https://www.wallbridgemining.com/s/fenelon.asp.

<sup>(1) Table includes only assay results received since the latest press release dated June 2, 2021.
(2) Au cut at: 100 g/t Au for the Tabasco/Contact zones; 60 g/t Au for the Cayenne zones; 50 g/t Au for the Area 51 zones.
(3) Intervals containing visible gold ("VG").

Assay QA/QC and Qualified Persons

Drill core samples from the ongoing 2021 drill program at Fenelon are cut and bagged either on site or by contractors and transported to SGS Canada Inc., AGAT Laboratories Ltd. or Bureau Veritas Commodities Canada Ltd. for analysis. In 2020 samples were submitted to either SGS Canada Inc. or ALS Canada Ltd. for analysis. Samples, along with standards and blanks that are included for quality assurance and quality control, were prepared and analyzed at the laboratories. Samples are crushed to 90% less than 2mm. A 1kg riffle split is pulverized to 85% passing 75 microns. 50g samples are analyzed by fire assay and AAS. At SGS, AGAT and Bureau Veritas samples >10g/t Au are automatically analyzed by fire assay with gravimetric finish or screen metallic analysis. To test for coarse free gold and for additional quality assurance and quality control, Wallbridge requests screen metallic analysis for samples containing visible gold. These and future assay results may vary from time to time due to re-analysis for quality assurance and quality control.

The Company intends to complete a maiden mineral resource on the Fenelon Gold System in the third quarter of 2021.

Wallbridge now holds several kilometres surrounding its rapidly expanding Fenelon discovery providing room for growth, as well as future mine development flexibility. Wallbridge's land holdings in Qu?bec along the Detour-Fenelon Gold Trend are over 900.0 km², improving Wallbridge's potential for further discoveries for over 90-kilometre strike length in this under-explored belt.
