Toronto, Ontario – March 8, 2023 – Wallbridge Mining Company Limited (TSX:WM, OTCQX:WLBMF) ("Wallbridge" or the "Company") is pleased to report the commencement of its 2023 drill program to test new exploration targets surrounding the 2023 Mineral Resource Estimate ("MRE") footprint at its Fenelon gold project ("Fenelon"), in addition to exploration drilling at Martiniere and other prospective greenfield targets on the Company's Detour-Fenelon Gold Trend Property

In February, Wallbridge mobilized three drills to Fenelon to test some of the prospective areas surrounding the existing deposit, which are described in more detail below. These were developed through the interpretation of combined geologic and geophysical data as well as, where present, historic drill results. 

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

"In addition to drilling in the vicinity of the Fenelon deposit targeting larger step-outs on the existing zones (see March 6, 2023 Press Release), our 2023 drill program is testing various targets on a regional scale. These will focus on areas of promising geology such as favorable host rocks and structures with the objective of identifying new zones of mineralization elsewhere on the Company's 830 km² Detour-Fenelon Gold Trend Property. In April two of the drills will be mobilized to Martiniere to commence exploration drilling with similar objectives of assessing the deposit's size potential and discovery of nearby zones." 

2023 Fenelon Exploration Drill Targets 

The Jeremie Diorite has been identified as a key host rock for gold mineralization at Fenelon, which is associated with quartz veining within the body itself (Area 51 and Ripley), as well as along the contact of the intrusion (Contact Zone) and into the sediments (Tabasco and Cayenne). In addition to the diorite, the Jeremie Fault represents another key control on the distribution of the gold mineralization. It is interpreted as a long-lived fault with multiple stages of activation, of which one phase is interpreted to be linked to the mineralizing event. 

The 2023 drill program at Fenelon will focus on testing exploration targets on the property using knowledge that has been gained through the development of the Fenelon resource since discovery. In addition to the immediate extensions of known zones, several targets have been identified in the area surrounding the Fenelon deposit (see Figure 2) that are of interest for this year's program:

1. Northwest magnetic low: This target was identified through the re-processing of the 2020 drone-magnetics data, revealing geophysical signatures that are comparable to the Jeremie Diorite. Preliminary results from the first two 2023 drill holes testing this target area have intersected a unit that is visually comparable to the Jeremie Diorite, containing zones of alteration with trace chalcopyrite mineralization. These results have established a large area of favorable geology for future exploration. 

2. West magnetic fold: In many orogenic gold deposits, the hinges of folds play an important role in controlling gold mineralization. A potential fold hinge has been identified through geophysics, approximately three kilometres to the west of the deposit.

3. Jeremie Fault corridor to the west: Based on magnetic signatures, the Jeremie Fault is interpreted to extend several kilometres beyond the western limits of the Fenelon deposit.

4. Magnetic high and electro-magnetic ("EM") plates: A massive sulfide layer, similar to the one occurring adjacent to the Fenelon deposit, exhibiting strong magnetic and EM responses can be traced across the property providing new exploration targets to the east. 

5. Jeremie Fault corridor to the east: This target is immediately southeast of, and interpreted to be within, the same geologically favourable gold hosting environment as Target 4.

6. East magnetic low: Approximately three to four kilometres to the east of the deposit is a magnetic low that has a similar signature to the Jeremie Diorite with a corresponding E-W structure.

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 in Québec's Northern Abitibi region. An updated mineral resource estimate completed in January 2023 yielded significantly improved grades and additional ounces at the 100%-owned Fenelon and Martiniere properties, incorporating a combined 3.05 million ounces of Indicated gold resources and 2.35 million ounces of Inferred gold resources. Fenelon and Martiniere are located within an 830 km² exploration land package controlled by Wallbridge. The Company believes that these two deposits have good potential for economic development, especially given their proximity to existing hydro-electric power and transportation infrastructure. In addition, Wallbridge believes that the extensive land package is extremely prospective for the discovery of additional gold deposits.

Wallbridge also holds a 19.9% interest in the common shares of Archer Exploration Corp. ("Archer") as a result of the sale of the Company's portfolio of nickel assets in Ontario and Québec in November of 2022.

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.
