Wallbridge Establishes Underground Access to Area 51 Mineralization at Fenelon and Confirms Continuity and Grade

TORONTO, March 24, 2022 - Wallbridge Mining Company Ltd. (TSX:WM, OTCQX:WLBMF) ("Wallbridge" or the "Company") today announced that it has completed an underground development program that provides direct access to the Area 51 zone of the Fenelon Gold Property ("Fenelon" or the "Property") for the first time, a significant milestone for Fenelon.

Preliminary results of tightly spaced underground drilling, geologic mapping and grade control sampling have confirmed the geological modeling and interpretation derived from surface drilling. This includes confirmation of a robust network of mineralized veins with strong continuity over a wide section of more than 30 metres, with grade continuity meeting or exceeding expectations for Area 51.

"After completing approximately 1,800 meters of underground development, we have had our first opportunity to see and touch Area 51 gold mineralization since our team discovered this zone in 2019, and everything we've observed so far increases our confidence in the quality and potential of this deposit," said Attila P?ntek, Wallbridge's Vice President, Exploration. "Underground access to Area 51 will allow us to obtain invaluable data that we need to further grow our existing gold resources and improve our understanding of the mineralization and grade distribution."

Wallbridge is focused on advancing Fenelon, as well as the nearby Martiniere property, located within the Company's 910-square-kilometre land package on an underexplored portion of the highly prolific Abitibi Greenstone Belt in Northwestern Quebec. Both Fenelon and Martiniere have the potential to support open pit and underground mining and are located close to existing power and transportation infrastructure.

Program Highlights:

Underground Development Completed

The Company completed approximately 1,800 metres of underground development over the course of 2021 and early 2022, providing access to Area 51 gold mineralization and establishing drilling platforms to be used in future resource drill programs (see Figs. 1 and 2). Existing workings, which reached a vertical depth of 185 metres below surface, are being maintained for exploration work.

Preliminary Underground In-fill Drill Results

After establishing underground access, three infill drill holes totaling 649 metres were completed at a nominal 25-metre spacing to target the Interstellar 03 Zone of the Area 51 gold system.

In contrast to surface drill holes, which followed a typical south to north drill pattern, these holes were drilled from east to west crossing the veins. All three holes successfully intersected the zone where expected and confirmed the anticipated orientation and grade distribution of the mineralization, with assay results of 2.23 g/t Au over 25.35 metres, including 11.77 g/t Au over 2.85 metres in hole 21-5080-003, as well as 0.68 g/t Au over 10.50 metres in 21-5080-001 (see Figs. 2 and 3). Assay results for the third underground hole are currently pending.

Geologic Mapping and Sampling

The new underground exploration drift revealed excellent exposures of typical Area 51 mineralization and its main host rock, the Jeremie Diorite, over a 30-metre distance. A network of sulfide-rich quartz veins characteristic of gold-bearing systems is clearly visible on the walls (see Fig. 4). The individual veins show excellent continuities of up to several metres across the drift, suggesting the deposit could be suitable for bulk mining methods.

Muck samples of 12 rounds within the Area 51 mineralized zone, representing 2,836 tonnes of material, returned an average grade of 1.94 g/t Au, which compares favourably to the grade profile contained in the Company's 2021 mineral resource estimate for Fenelon. This grade control (muck and chip) sampling will aid in the interpretation of future mineral resource estimates and evaluation of potential mining methods in economic studies.

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 providing 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 continuity. An inferred mineral resource has a lower level of confidence than that applying to 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 mineable. 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 mineral 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 purported 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.
