Wallbridge’s First Drill Hole at Casault Intersects New Gold Mineralization

Toronto, Ontario – October 21, 2021 – Wallbridge Mining Company Limited (TSX:WM) (“Wallbridge” or the

“Company”) is pleased to report that a mineralized zone in CAS-21-123, th e first drill hole of this summer’s 5,300 metre

drill program on the Casault Gold Property (“Casault” or the “Property”), has assayed 6.85 g/t Au over 2.00 metres.

This intersection is considered significant as it is located in the northern, largely untested part of the property, where no

gold zone has been identified to date. This hole was collared a pproximately 2 kilometres from the nearest anomalous gold

intersections (> 1 g/t Au over 1 m) on both the Casault and Martiniere properties (see Fig. 2).

This hole is one of 13 drilled over the last few months to test a variety of grassroots exploration targets 4 to 12 kilometres

west of the Company’s Martiniere Gold Property ("Martiniere").

The other 12 drill holes of the Casault program have also inter sected strong shear and alteration zones with sulfide

mineralization that are interpreted to potentially be part of g old-bearing systems. Assay results of these drill holes are

pending and will be released as they become available.

“This intersection of encouraging gold mineralization in the first drill hole of our Casault program in an entirely grassroots

area is not only a testament to our growing understanding of the regional controls on gold deposition in the Detour-Fenelon

area but also to the prospectivity of the over 900 square kilometre land package along this underexplored belt”, stated

Marz Kord, President & CEO of Wallbri dge. “We are keenly awaiting the assay results of other completed holes and are

looking forward to following-up on this intersection.”

Casault Gold Property

Wallbridge has an option to acquire up to a 65% interest in the 177 km 2 Casault Property from Midland Exploration

(“Midland”) (see Wallbridge News Release dated June 18, 2020). Casault covers a number of grassroots exploration targets

4 to 12 kilometres west of the Company’s Martiniere Gold Projec t ("Martiniere") and 34 to 41 kilometres west of its

flagship Fenelon gold property ("Fenelon") (see Figs. 1 and 2). The property covers more than 20 kilometres of the Sunday

Lake Deformation Zone ( “SDLZ”), along which the Company’s Mar tiniere and Fenelon gold deposi ts are located and

which also hosts Kirkland Lake Gold’s world-class Detour Lake Mine.

The Casault property also hosts the Vortex Zone, a syenite-associated disseminated gold system with drill hole intersections

grading up to 1.38 g/t Au over 26.5 metres that was traced over a distance of 1.5 kilometres.

Drill Program Completed

Between July and September 2021, Wallbridge completed a 13-hole drill program, testing a variety of grassroots exploration

targets at Casault. Drilling has focused on the unexplored nort hern part of the Property, within 1 to 2 kilometres north of

the SLDZ, on the same assemblage of rocks that hosts the Compan y’s Martiniere gold system. Martiniere hosts historic

indicated resources of approximately 591,000 gold ounces with an updated resource estimate currently underway (see details

of the historic resource estimate on the Company’s website). The initial drilling at Casault was approximately 5 kilometres

east of the closest target tested by the 2021 drilling at Martiniere.

Hole CAS-21-123 tested a prominent NW-SE oriented structure int erpreted from airborne magnetics (see Fig. 3). This

structural orientation is known to control gold mineralization at Fenelon and Martiniere, and a series of large structures of

this trend also transects the Casault property. The particular structure tested by CAS-21-123 extends for an approximately

8 kilometres across the Company’s Martiniere, Casault and Doigt properties and was historically tested by one drill hole on

Martiniere, yielding 30.40 g/t Au over 0.44 metres, which has not yet been followed-up.

The intersection of 6.85 g/t Au over 2.00 metres in CAS-21-123 is associated with a mineralized zone consisting of

chalcopyrite, pyrite, pyrrhotite, and electrum, a gold-silver m ineral phase, hosted within deformed and heavily carbonate-

altered, felsic to intermediate, porphyritic rocks.

2021 Detour-Fenelon Gold Trend Regional Drill Program

This drilling completed at Casault is part of the Company’s app roximately 20,000 to 25,000- metre regional drill program

on the Company’s district-scale, underexplored land package on the Detour-Fenelon Gold Trend.

Assay results of one drill hole of the 2021 Casault exploration drill pr ogram are reported in the Tabl e 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://wallbridgemining.com/our-projects/detour-gold-trend/casault/.

Assay QA/QC and Qualified Persons

Drill core samples from the 2021 drill program at Casault were cut and bagged on site and transported to AGAT Laboratories

Ltd. for analysis. Samples are crushed to 75% less than 2mm. A 250g riffle split is pulverized to 85% passing 75 microns.

gravimetric finish or screen metallic analysis. To test for coa rse free gold and for additiona l quality assurance and quality

control, Wallbridge requests screen metallic analysis for sampl es containing visible gold. These and future assay results

may vary from time to time due to re‒analysis for quality assurance and quality control.
