Toronto, Ontario – September 8, 2022 – Wallbridge Mining Company Limited (TSX:WM, OTCQX:WLBMF) (“Wallbridge” or the “Company”) today announced that it has commissioned an update to the 2021 mineral resource estimate for its flagship Fenelon Gold (“Fenelon”) and Martiniere (“Martiniere”) project (the “2023 MRE”). In addition, the Company has initiated a preliminary economic assessment (“PEA”) of Fenelon.

For Fenelon, the 2023 MRE will incorporate data from an additional 100,000 metres of drilling completed since the 2021 MRE, and will focus on optimizing the resource for a predominantly underground bulk mining operation, as opposed to the less selective large open pit approach used in 2021.  The 2023 MRE will also include an updated resource for Martiniere, situated 30 km west of Fenelon, where the Company has completed an additional 30,000 metres of drilling since the 2021 MRE.

The 2023 MRE, expected to be completed in the first quarter of 2023, will form the foundation for a PEA which will assess the potential for a predominantly underground bulk mining operation at Fenelon. The PEA is expected to be completed by end of second quarter 2023.

Marz Kord, President and CEO of Wallbridge commented:

“The drilling and underground exploration work we have completed at Fenelon since our initial 2021 MRE has increased our confidence in the geometry of the mineralization. We have identified mineralized zones that show continuity over several metres in thickness and tens of metres in strike length, with average grades above three grams per tonne. This has led us to consider modelling most of the deposit as an underground bulk mineable resource, analogous to other underground bulk mining operations located on the Abitibi Greenstone Belt, rather than the less selective open pit mining approach used in 2021, when drilling density at the project was lower.”

Marz Kord continued: “The commencement of a preliminary economic assessment and updated mineral resource estimates represent a major stepping stone in bringing Fenelon closer to production. Assets of this quality and location are increasingly rare and we believe there will be significant opportunities to create shareholder value as we continue to de-risk and advance the projects.

A bulk underground mining operation at Fenelon has a number of critical advantages over the less selective, deep open-pit/underground approach contemplated in the 2021 MRE. These benefits include lower upfront capital requirements, a smaller surface footprint with significantly less environmental disturbance - an approach which is more favorable to local communities, and a potentially shorter permitting timeline.”

Fenelon is located 75 kilometres east of the Detour Lake gold mine, at the centre of Wallbridge’s strategic land package which covers roughly 910 square kilometres of the most prospective ground on the Detour-Fenelon Gold Trend in Northern Abitibi, Quebec. Martiniere is located 30 kilometres west of Fenelon.

The quality of the gold resources at Fenelon and Martiniere have the potential to improve further. Beyond these known gold resources, the Company sees strong potential to make additional discoveries on its large, prospective Detour-Fenelon Gold Trend land package spanning 97 kilometres of strike length. The Detour-Fenelon Gold Trend is a vast area that remains largely unexplored compared with the southern portion of the Abitibi Greenstone Belt where more than 100 million ounces of gold has been produced over a similar strike distance.

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 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 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 Company’s focus on gold and in line with its strategy to unlock the value of its nickel assets, on July 13, 2022 Wallbridge announced 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 portfolio of nickel assets 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.This news release has been authorized by the undersigned on behalf of Wallbridge Mining Company Limited.

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.
