Wallbridge’s Regional Grassroots Exploration Delivers Positive Results Near Fenelon and Martiniere

TORONTO, March 30, 2022 - Wallbridge Mining Company Ltd. (TSX:WM, OTCQX:WLBMF) ("Wallbridge" or the "Company") today reported a new round of positive drill results from the Company's regional exploration program on the Detour-Fenelon Gold Trend, which is targeting the discovery of satellite deposits and new mineralized zones near the Company's Fenelon Gold and Martiniere projects ("Fenelon" and "Martiniere") in Northwestern Quebec.

Highlights:

• New gold mineralization, including 42.63 g/t Au over 0.50 metre and 9.98 g/t Au over 0.60 metre, was intercepted on the Grasset Property ("Grasset"), less than 10 kilometres east of the Fenelon deposit.
• A new gold system was identified in the northeastern portion of the Casault Gold Property ("Casault"), adjacent to Martiniere.

"Wallbridge's district-scale property on the Detour-Fenelon Gold Trend covers an area roughly the same distance as Rouyn-Noranda to Val d'Or, yet it is comparatively underexplored. We continue to see excellent potential for additional gold discoveries, with the opportunity to add to our existing resource base at Fenelon and Martiniere," said Attila P?ntek, Wallbridge's Vice President, Exploration. "Approximately 10% of our 2022 exploration budget is dedicated to grassroots exploration on our properties in this district. Initial programs at Casault and Grasset have already delivered some very positive results and we are confident that we can continue to build on this success over the course of the year."

Grasset Exploration Drilling

Between November 2021 and February 2022, Wallbridge carried out exploration drilling 10 kilometres south-east of the Fenelon deposit, to follow-up on the Grasset Gold showing, where historic intersections include 1.66 g/t Au over 33 metres, with higher grade sub-intervals, such as 6.15 g/t Au over 4.04 metres.

One of the first drill holes of the program, GR-21-109 intersected sulfide-bearing quartz-carbonate veining containing visible gold, assaying 42.63 g/t Au over 0.50 metre. Gold mineralization in this area is hosted by gabbroic intrusive host rocks adjacent to the Sunday Lake Deformation Zone ("SLDZ"), which has an associated unit of thick polymictic conglomerates and is represented by strong brittle-ductile deformation zones. Another drill hole, FA-21-328, testing interpreted structures adjacent to the SLDZ, discovered new gold mineralization with assay results up to 9.98 g/t Au over 0.60 metre.

The geology and orientation of the deformation zones in these holes is similar to the Fenelon gold deposit, and analogous to other well-known gold deposits in the southern Abitibi. Given this very favorable environment for hosting gold mineralization, the Company will continue to explore for new gold zones that may have synergies with a future operation at Fenelon.

Casault Exploration Drilling

As reported in a Wallbridge news release dated October 21, 2021, the Company completed a 13-hole drill program totaling 5,300 metres to test grassroots targets on the unexplored northern part of Casault. This area, one to two kilometres north of the SLDZ, includes the same assemblage of rocks that hosts the Company's Martiniere gold deposit.

In addition to 6.85 g/t Au over 2.00 metres in CAS-21-123 previously reported, the drill program successfully identified gold mineralization near the eastern border of the property, toward Martiniere. Drill holes CAS-21-126 to CAS-21-130 all intersected anomalous gold mineralization (see Table 1) associated with a volcanic assemblage, a newly discovered ultramafic intrusive complex and the same northwest-southeast structure that is interpreted to control the mineralization intersected in hole CAS-21-123. Structures of this orientation are known to be important conduits for gold at Fenelon, Martiniere, and as reported here, at Grasset and Casault.

A follow-up drill program further testing this newly identified gold mineralized environment will be completed in the second quarter of 2022.

Wallbridge has an option to acquire up to a 65% interest in the 177-square-kilometre Casault Property from Midland Exploration ("Midland") (see Wallbridge news release dated June 18, 2020). Casault covers a number of grassroots exploration targets four to 12 kilometres west of Martiniere and 34 to 41 kilometres west of Fenelon (see Figs. 1 and 3). The property encompasses more than 20 kilometres of the SLDZ, which hosts the Company's Martiniere and Fenelon gold deposits and the world-class Detour Lake mine.

Detour-Fenelon Gold Trend Grassroots Exploration

An unmanned aerial vehicle ("UAV") geophysical magnetic survey was completed in the first quarter of 2022 over the Harri Property, which covers 20 kilometres of the SLDZ between the Fenelon and Martiniere projects and the eastern portion of Casault. The purpose of the survey was to provide high resolution magnetic data to help in geologic and structural interpretation and target generation. Such magnetic data has been invaluable at Fenelon in guiding exploration to recognize gold-bearing and other structures.

Further grassroots exploration programs completed in the first quarter of 2022 or planned for later in the year include: biogeochemical (tree bark) sampling, till sampling, outcrop mapping and prospecting, as well as additional UAV magnetics, all with the aim of providing additional geologic information to better define drill targets and improve discovery success.

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.
