Wallbridge Drilling Identifies Further Growth Potential for Martiniere

Gold Resources

Assay Highlights Include:

• 4.07 g/t Au over 24.10 metres, including 67.65 g/t Au over 1.10 metres

• 15.90 g/t Au over 3.00 metres

• 19.31 g/t Au over 1.70 metres

Toronto, Ontario – October 12, 2022 – Wallbridge Mining Company Limited (TSX:WM,

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

one of the final holes of its 2022 drill program at the Martiniere Gold Project (“Martiniere” or the

“Project”) continue to demonstrate excellent resource growth potential.

Martiniere is located 30 kilometres and within trucking distance of the Company’s flagship Fenelon

gold project (“Fenelon”) and 45 kilometres east of the Detour Lake gold mine on the highly

prospective Detour -Fenelon Gold Trend in Northern Abitibi, Quebec . The 2021 -2022 drilling

program was primarily designed to establish connections between the Martiniere West and Bug

Lake Trends (see Figure 1) and also included several exploration holes, drilling larger-spaced step-

outs on the gold -bearing trends and zones . The results announced today come from such a n

exploration hole, MR-22-036, testing the eastern extent of the gold system. Assay results from the

last two exploration drill holes of the 2022 program are pending.

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

“The results reported today reveal the presence of gold mineralization several hundred metres east

of the current mineral resource footprint. This is important because it opens up a new direction for

future exploration and resource expansion at Martiniere.”

These new mineralized zones are associated with porphyritic intrusive rocks, similar to the Bug Lake

Porphyry, one of the main controls on gold mineralization at Martiniere.”

All figures and a table with drill hole information of recently completed holes are posted on the

Company’s website under “Curren t 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 by the Company, will p rovide significant new data for

an updated mineral resource estimate (“MRE”) at Martiniere scheduled for the first quarter of 2023.

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 46.76 g/t Au over

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

Highlights of the 2022 drill program were reported in the Company’s press release dated August

30, 2022 and 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, expanding 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.

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 maximum vertical depth of 400 metres and mineralized

shoots remain open down-plunge.

In August, the Company signed a landmark Pre -Development Agreement with its Cree Nation

Partners, who have agreed to support and cooperate on Wallbridge’s activities on the Detour -

Fenelon Gold Trend.

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 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 ar e analyzed 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 techni cal content of this press release is Peter Lauder,

Information Concerning Estimates of Mineral Resources

The disclosure in this press release and referred to herein was prepared in accordance with NI 43-101 which

differs significantly from the requirements of the U.S. Securities and Exchange Commission (the "SEC"). The

terms "measured mineral resource", "indicated mineral resource" and "inferred mineral resource" used in this

press release are in reference to the mining terms defined in the Canadian Institute of Mining, Metallurgy and

Petroleum Standards (the " CIM Definition Standards"), which definitions have been adopted by NI 43 -101.

Accordingly, information contained in this press release providin g descriptions of our mineral deposits in

accordance with NI 43 -101 may not be comparable to similar information made public by other U.S.

companies subject to the United States federal securities laws and the rules and regulations thereunder.

Investors are cautioned not to assume that any part or all of mineral resources will ever be converted into

reserves. Pursuant to CIM Definition Standards, "inferred mineral resources" are that part of a mineral

resource for which quantity and grade or quality are estimated on the basis of limited geological evidence and

sampling. Such geological evidence is sufficient to imply but not verify geological and grade or quality

WALLBRIDGE MINING COMPANY LIMITED

continuity. An inferred mineral resource has a lower level of confidence than that applying t o an indicated

mineral resource and must not be converted to a mineral reserve. However, it is reasonably expected that the

majority of inferred mineral resources could be upgraded to indicated mineral resources with continued

exploration. Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility

or pre-feasibility studies, except in rare cases. Investors are cautioned not to assume that all or any part of

an inferred mineral resource is economically or legally min eable. Disclosure of "contained ounces" in a

resource is permitted disclosure under Canadian regulations; however, the SEC normally only permits issuers

to report mineralization that does not constitute "reserves" by SEC standards as in place tonnage and grade

without reference to unit measures.

Canadian standards, including the CIM Definition Standards and NI 43-101, differ significantly from standards

in the SEC Industry Guide 7. Effective February 25, 2019, the SEC adopted new mining disclosure rules

under subpart 1300 of Regulation S -K of the United States Securities Act of 1933, as amended (the " SEC

Modernization Rules"), with compliance required for the first fiscal year beginning on or after January 1,

2021. The SEC Modernization Rules replace the historical property disclosure requirements included in SEC

Industry Guide 7. As a result of the adoption of the SEC Modernization Rules, the SEC now recognizes

estimates of "measured mineral resources", "indicated mineral resources" and "inferred minera l resources".

Information regarding mineral resources contained or referenced in this press release may not be comparable

to similar information made public by companies that report according to U.S. standards. While the SEC

Modernization Rules are purpo rted to be "substantially similar" to the CIM Definition Standards, readers are

cautioned that there are differences between the SEC Modernization Rules and the CIM Definitions Standards.

Accordingly, there is no assurance any mineral resources that the Company may report as "measured mineral

resources", "indicated mineral resources" and "inferred mineral resources" under NI 43 -101 would be the

same had the Company prepared the resource estimates under the standards adopted under the SEC

Modernization Rules.
