Fenelon In-Fill Sampling Program Continues to Yield Strong Gold Mineralization

TORONTO, Oct. 20, 2022 - Wallbridge Mining Company Ltd. (TSX:WM, OTCQX:WLBMF) ("Wallbridge" or the "Company") is pleased to report that new assay results from the in-fill sampling program at its 100%-owned Fenelon Gold Project ("Fenelon" or the "Project") have yielded additional gold mineralization from previously unsampled sections of drill core within and adjacent to the Project's existing Mineral Resource Estimate ("MRE"). The results from this program will be incorporated into the MRE update and Preliminary Economic Assessment ("PEA") currently underway at Fenelon.

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

"Launched earlier this year, our systematic in-fill sampling program continues to deliver excellent results, providing a cost-efficient method of identifying additional gold mineralization that can be incorporated into the next MRE update for Fenelon, expected in the first quarter of 2023, followed by a PEA for the project by the end of the second quarter of next year."

"The high-grade interval of 72.00 g/t Au over 1.50 metres from the Contact Zone in hole FA-20-195, one of the northwestern-most intersections of this zone, is very important because it underscores the potential for additional resource growth in this direction. In addition, the intersection of 15.12 g/t Au over 1.00 metre from FA-06-270 is at a very shallow depth in the Tabasco Zone, allowing for further expansion of mineralization in an area where recent intersections have also revealed strong gold mineralization."

Wallbridge has prioritized more than 30,000 metres of previously unsampled drill core for in-fill sampling in 2022. This evaluation focuses on intervals that occur within or adjacent to known mineralized zones. To date, results for approximately 23,500 metres have been received.

Assay result highlights announced today include:

In-fill assay results of previously unsampled core from four exploration drill holes drilled between 2006 and 2021 are reported in the table 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/fenelon-gold/.

Fenelon is located within Wallbridge's 910-square-kilometre land package on the Detour-Fenelon Gold Trend, 80 kilometres east of the Detour Lake gold mine.

Assay QA/QC and Qualified Persons

Drill core samples from the ongoing drill program at Fenelon 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 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 technical content of this press release is Peter Lauder, P.Geo., Exploration Manager of Wallbridge.

About Wallbridge Mining

Wallbridge is focused on creating value through the exploration and sustainable development of gold projects along the Detour-Fenelon Gold Trend while respecting the environment and communities where it operates.

Wallbridge's flagship project, Fenelon Gold ("Fenelon"), is located on the highly prospective Detour-Fenelon Gold Trend Property ("Detour-Fenelon Gold Trend Property") in Northern Abitibi. A mineral resource estimate completed in 2021 validated the multi-million-ounce potential of the 100%-owned Fenelon and Martiniere properties, 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 km² exploration land package controlled by Wallbridge, have the potential to be developed into mines and are close to existing power and transportation infrastructure.

Wallbridge also holds a portfolio of nickel assets ("Nickel Assets") in Ontario and Quebec. In line with its strategy to unlock the value of its Nickel Assets, Wallbridge announced on July 13, 2022, that it has entered into a definitive agreement with Archer Exploration Corp. ("Archer"), pursuant to which, Archer will acquire all of Wallbridge's property, assets, rights and obligations related to its Nickel Assets, including Grasset, to create a focused and well-funded publicly traded nickel exploration and development company.

Wallbridge will continue to focus on its core Detour-Fenelon Gold Trend Property while enabling shareholders to participate in the potential economic upside in Archer.

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.
