New Assay Results Expand Martiniere Gold Zones

Toronto, Ontario – August 30, 2022 – Wallbridge Mining Company Limited (TSX:WM,

OTCQX:WLBMF) (“Wallbridge” or the “Company”) is pleased to announce that positive assay

results continue to validate the resource growth potential of the Martiniere Gold Property

(“Martiniere” or the “Property”). Martiniere is located 30 kilometres and within trucking distance

of the Company’s flagship Fenelon Gold P roject (“Fenelon”) on the highly prospective Detour -

Fenelon Gold Trend in Northern Abitibi, Quebec (Figure 1).

New results announced today include: 12.27 g/t Au over 5.60 metres in hole MR-22-026, extending

the Martiniere West zone along strike by over 400 metres to the southwest; 4.75 g/t Au over 5.50

metres in hole MR-22-020, extending the Martiniere West zone down-plunge by over 300 metres;

and 2.50 g/t Au over 17.35 metres , near-surface in hole MR -22-029 in the area between the

Martiniere West and Central zones.

Attila Péntek, Wallbridge’s Vice President, Exploration, commented:

“Our 2021-2022 exploration program at Martiniere has provided essential geologic information on

the orientation of the gold zones and their host rocks and has demonstrated resource expansion

potential in multiple directions . We see excellent opportunities to add to the existing resource ,

including at shallow depths, as in hole MR-22-029, and the deposit remains largely untested below

400 metres from the surface. We will use the remainder of the year to incorporate this new data,

along with pending assays from three more exploration holes, into our geology models, in

preparation for an updated Mineral Resource Estimate and planning for our 2023 exploration

program at the property.”

About the Martiniere Gold Property

Martiniere currently contains 544,000 ounces of indicated gold resources and 256,000 ounces of

inferred gold resources within a large, mineralized footprint of four-square kilometres. The deposit

has only been meaningfully drilled to a vertical depth of 400 metres and mineralized shoots remain

open down-plunge.

The Company’s 2021-2022 drilling program was primarily aimed at establishing connections

between the Martiniere West and Bug Lake Trends , where significant gaps in previous drilling

existed, in order to establish a continuous deposit.

Assay results from 40 drill holes of the 2021-2022 Martiniere drill program are reported in the Table

and Figures below. Further assays results are pending for three drill holes of the 2022 program. 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/martiniere/.

The 2021-2022 Drill Program at Martiniere

Following an initial drill program of 9,380 metres in 2021, the Company has completed 21,400

metres of additional drilling at Martiniere this year. The results from this program, which now

includes more than 30,000 metres of drilling, will provide significant new data for an updated

resource estimate at Martiniere.

Highlights of the 2021 drill program, as reported in the Company’s press releases dated October

26, 2021 and February 2, 2022, include 3.68 g/t Au over 22.50 metres in MDE-21-326 (Bug Lake

North), 2.21 g/t Au over 36.60 metres in MDE-21-328 (Bug Lake South) and 46.75 g/t Au over

2.40 metres in MDE-21-338 (Martiniere Central).

The three drill rigs operating at Martiniere were redeployed to Fenelon in June where they are

providing additional resources for an updated mineral resource estimate focused on defining an

underground bulk mineable resource at Fenelon.

Assay QA/QC and Qualified Persons

Drill core samples from the ongoing drill program at Martiniere are cut and bagged either on-site or

by contractors and transported to SGS Canada Inc. or Bureau Veritas Commodities Canada Ltd. for

analysis. Samples, standards and blanks 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 anal yzed by fire assay and AAS or

ICP. At SGS 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 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 Qualified Person responsible for the technical co ntent of this press release is Peter Lauder,

P.Geo, Exploration Manager of Wallbridge.

About Wallbridge Mining

Wallbridge is focused on creating value through the acquisition, exploration, discovery,

development, and production of gold from a portfolio of advanced exploration-stage assets located

in established mining jurisdictions within Canada. In doing so, Wallbridge aims to be a partner in

sustainable development, supporting the prosperity of employees, First Nations, and local

communities while protecting the environment.

Wallbridge’s flagship project, Fenelon, is located on the highly prospective Detour -Fenelon Gold

Trend Property in Northern Abitibi. A mineral resource estimate completed in 2021 validated the

multi-million-ounce potential of Fenelon and Martiniere, incorporating a combined 2.67 million

ounces of indicated gold resources and 1.72 million ounces of inferred gold resources. Fenelon and

Martiniere, located within a 910 km 2 exploration land package controlled by Wallbridge, hav e the

potential to be developed into mines and are close to existing power and transportation

infrastructure.

Wallbridge also has interests in a portfolio of nickel assets. These include a 100% interest in the

Grasset Property in Quebec, and a 20.4% interest in Lonmin Canada Inc., which owns 100% of the

Denison nickel, copper and PGM project southwest of Sudbury, Ontario. In keeping with the
