Wallbridge Announces Mineral Resource Estimate for Fenelon and Martiniere Deposits on Detour-Fenelon Gold Trend

• Total combined Indicated Resource of 2.67 million ounces: 43.56 Mt grading 1.91 g/t Au.
  
• Total combined Inferred Resource of 1.72 million ounces: 31.78 Mt grading 1.69 g/t Au.
• Fenelon has evolved from a small high-grade underground deposit to a multi-million-ounce potential open pit and underground bulk mineable deposit.
• Significant expansion potential in multiple directions laterally and at depth at both Fenelon and Martiniere.

TORONTO, Nov. 09, 2021 -- Wallbridge Mining Company Ltd. (TSX: WM, OTCQX:WLBMF) ("Wallbridge" or the "Company") is pleased to announce its maiden Mineral Resource Estimate ("MRE") for the Fenelon gold property and an updated MRE for the Martiniere gold property, both located on the Company's 910 km² land position on the Detour-Fenelon Gold Trend (see Figure 1) in Northern Abitibi, Quebec.

The table below summarizes the MREs for Fenelon and Martiniere.

Detour Fenelon Gold Trend (effective date of November 9, 2021)

"Our maiden MRE demonstrates how Fenelon has rapidly evolved and continues to grow. We started with a small high-grade deposit and now, with the discovery of and subsequent drilling on the Tabasco/Cayenne and Area 51 zones, we have a multi-million-ounce deposit amenable to potential open pit and underground bulk mining," said Marz Kord, President & CEO of Wallbridge. "Together with an updated MRE for Martiniere, which is located 30 km west of Fenelon, the Fenelon MRE strengthens our vision of establishing multiple gold producing assets sharing centralized infrastructure on the Detour-Fenelon Gold Trend. These two gold deposits remain open in multiple directions laterally and at depth indicating significant potential for expansion. Our next step is additional drilling to add to these resources prior to proceeding with an economic study and to identify new mineralization elsewhere on the Detour-Fenelon Gold Trend."

Attila P?ntek, Vice President Exploration of Wallbridge, added: "That over 60% of the mineral resource is classified as Indicated is a testament to the quality of the Fenelon deposit with good geologic continuities and all the zones being situated close to each other allowing for efficient, cost-effective drilling. We are also very pleased with the increase in the Martiniere mineral resource from the previous MRE, completed in 2018, and our ongoing drill program has already demonstrated excellent potential for Martiniere to become our next significant gold deposit. We are proud of the tremendous effort of our team and contractors for advancing Fenelon from gold discovery to this significant MRE in less than three years, with the added challenge of doing so during a pandemic."

Mineral Resource Expansion Potential

There is significant potential to further expand mineral resources at both Fenelon and Martiniere as:

• The current Area 51 gold resource is open to the west and to the south, where gold mineralization is known to extend for 800 m, all the way to the Sunday Lake deformation zone (see Figure 2).
• Both Area 51 and Tabasco/Cayenne zones are open below 1,000 m depth and are known to extend as far as 1,500 m below surface (see Figure 3).
• Several isolated zones at Martiniere could be combined into one or two deposits with more tightly-spaced drilling (see Figure 4).
• Drilling is extending mineralization to depth at Martiniere (see Figure 5).

Mineral Resource Estimation Methodology

The maiden MRE for Fenelon is based on 1,040 recent and historic drill holes totaling approximately 358,000 m, variably spaced from 20 to 200 m on the Gabbro, Tabasco/Cayenne and Area 51 zones. This includes 650 drill holes totaling approximately 292,000 m drilled by Wallbridge since 2016 on the Tabasco/Cayenne and Area 51 zones.

The updated MRE for Martiniere is based on 111 recent and historic drill holes totaling over 40,000 m, variably spaced from 20 to 150 m on the Martiniere North, Martiniere West, Bug Lake and Horsefly zones. None of the holes drilled to date by Wallbridge since the acquisition of Balmoral have been incorporated into the Martiniere MRE.

For both deposits, the geological, litho-structural, and 3D modelling of the mineralized zones was prepared in Leapfrog Geo and the mineral resource estimates were prepared in Leapfrog Edge using a sub-block model of 6m x 6m x 6m parent blocks. Gold grades were calculated using the Ordinary Kriging interpolation method for Fenelon and the Inverse Distance-squared method using hard boundaries for Martiniere.

The mineral resources are categorized as Indicated and Inferred based on drill spacing, as well as geological and grade continuity. For Fenelon, in the Tabasco/Cayenne Zones, a maximum distance to the closest composite of 35 m for Indicated and 70 m for Inferred while 25 m was used for Indicated and 50 m for Inferred in all other zones. For Martiniere, maximum distance to the closest composite was 35 m for Indicated and 70 m for Inferred.

The reasonable prospect for an eventual economical extraction is met by having used reasonable cut-off grades both for a potential open pit and underground extraction scenarios, a minimum width, and constraining volumes (Deswik shapes and optimized pit-shell). The cut-off calculation is based on the assumed parameters listed below:

Fenelon (effective date of November 9, 2021)

Martiniere (effective date of November 9, 2021)

Note: Numbers may not add due to rounding

Notes on the MREs of the Fenelon and Martiniere gold projects:

1. The Qualified Persons for the current MREs are Mr. Carl Pelletier, P. Geo. (For Fenelon and Martiniere) and Mr. Vincent Nadeau-Benoit, P.Geo. (For Fenelon), both from InnovExplo. The MREs follow 2014 CIM Definition Standards and the 2019 CIM MRMR Best Practice Guidelines.
2. These mineral resources are not mineral reserves as they do not have demonstrated economic viability.
3. The qualified persons are not aware of any known environmental, permitting, legal, title-related, taxation, socio-political or marketing issues, or any other relevant issue, that could materially affect the potential development of mineral resources other than those discussed in the MRE.
4. For Fenelon, a density value of 2.80 g/cm³, supported by measurements, was applied to the bedrock. Sixty-one high-grade zones and five low-grade envelopes were modelled in 3D using a minimum true width of 2.0 m. High-grade capping was done on raw assay data and established on a per-zone basis and ranges between 25 g/t and 110 g/t Au (except Gabbro zones where it ranged from 35 g/t to 330 g/t) for the high-grade zones and ranges between 8 g/t and 35 g/t Au for the low-grade envelopes. Composites (1.5 m) were calculated within the zones and envelopes using the grade of the adjacent material when assayed or a value of zero when not assayed.
5. For Martiniere, a density value of 2.80 g/cm³, supported by measurements, was applied to the bedrock. Fifty-nine high-grade zones and one low-grade envelope were modelled in 3D using a minimum true width of 3.0 m. High-grade capping was done on raw assay data and established at 35 g/t Au based on the most numerous zones and extrapolated to all zones. Composites (1.0 m) were calculated within the zones and envelopes using the grade of the adjacent material when assayed or a value of zero when not assayed.
6. The reasonable prospect for eventual economic extraction is met by having constraining volumes applied to any blocks (potential surface or underground extraction scenario) using Whittle and the Deswik Stope Optimizer (DSO) and by the application of cut-off grades, as shown in the above table, were calculated using a gold price of US $ 1,607 / oz and an Exchange rate of US $ 1.31 / CAD $.
7. Results are presented in-situ. Ounce (troy) = metric tons x grade / 31.10348. The number of tonnes and ounces was rounded to the nearest thousand. Any discrepancies in the totals are due to rounding effects; rounding followed the recommendations as per NI 43-101.
   

The sensitivity of the cut-off grades on the mineral resources of the Fenelon and Martiniere gold project is presented below:

Sensitivity in-pit Fenelon

Sensitivity underground Fenelon

Sensitivity in-pit Martiniere

Sensitivity underground Martiniere

The tables above illustrate the sensitivity of each MRE to different cut-off grades for a potential open-pit and underground operation scenario with reasonable outlook for economic extraction. The reader is cautioned that the figures provided in these tables should not be interpreted as a statement of mineral resources. Quantities and estimated grades for different cut-off grades are presented for the sole purpose of demonstrating the sensitivity of the resource model to the choice of a specific cut-off grade.

Grasset MRE

Additional notes on the MRE of the Grasset project

1. The independent and qualified person for the 2021 MRE, as defined by NI 43-101, is Mr. Carl Pelletier, P. Geo. (InnovExplo Inc.). The effective date of the estimate is November 9, 2021.
2. These mineral resources are not mineral reserves as they do not have demonstrated economic viability.
3. The mineral resource estimate follows 2014 CIM Definition Standards and the 2019 CIM MRMR Best Practice Guidelines.
4. Two mineralized zones were modelled in 3D using a minimum true width of 3.0 m. Density values are interpolated from density databases, capped at 4.697 g/cm3
5. High-grade capping was done on raw assay data and established on a per zone basis for nickel (15.00%), copper (5.00%), platinum (5.00g/t) and palladium (8.00g/t). Composites (1-m) were calculated within the zones using the grade of the adjacent material when assayed or a value of zero when not assayed.
6. The estimate was completed using a block model in GEMS (v.6.8) using 5m x 5m x 5m blocks. Grade interpolation (Ni, Cu, Co, Pt, Pd, Au, and Ag) was obtained by ID2 using hard boundaries. Results in NiEq were calculated after interpolation of the individual metals.
7. The mineral resources are categorized as Indicated and Inferred based on drill spacing, geological and grade continuity. A maximum distance to the closest composite of 50 m was used for Indicated mineral resources and 100 m for the Inferred mineral resources.
8. The reasonable prospect for eventual economic extraction is met by having constraining volumes applied to any blocks (potential underground extraction scenario) using the Deswik Stope Optimizer (DSO) and by the application of a cut off grade of 0.80% NiEq. Cut-off calculations used: Mining = $65.00/t; Maintenance = $10.00/t; G&A = $20.00/t, Processing = $42.00/t. The cut-off grades should be re-evaluated in light of future prevailing market conditions (metal prices, exchange rate, mining cost, etc.). The NiEq formula used a USD:CAD exchange rate of 1.31, nickel price of US$6.51/lb, copper price of US$2.75/lb, cobalt price of US$14.48/lb, platinum price of US$887.68/oz, and palladium price of US$2,017.31/oz. Gold and silver does not contribute to the economics of the deposit.
9. Results are presented undiluted and in-situ. Ounce (troy) = metric tons x grade / 31.10348. Metric tons and ounces were rounded to the nearest hundred. Metal contents are presented in ounces and pounds. Any discrepancies in the totals are due to rounding effects; rounding followed the recommendations in NI 43-101.
10. The qualified person is not aware of any known environmental, permitting, legal, title-related, taxation, socio-political, marketing or other relevant issue that could materially affect the mineral resource estimate

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.
