Wallbridge Mineral Resource Estimate Delivers Significant
Increase in Grade at Detour-Fenelon Gold Trend Property
• Gold grade of Indicated and Inferred resources at Fenelon improves by 85% and
84%, respectively
• Substantial new resources added at Martiniere
Toronto, Ontario – January 17, 2023 – Wallbridge Mining Company Limited (TSX:WM,
OTCQX:WLBMF) (“Wallbridge” or the “Company”) is pleased to announce an updated
mineral resource estimate (“MRE”) for its Fenelon Gold (“Fenelon”) and Martiniere Gold
(“Martiniere”) projects, located on the Company’s Detour- Fenelon Gold Trend land
package in Northern Abitibi, Quebec.
Marz Kord, President & CEO of Wallbridge stated:
“Building on the success of our 2021 maiden MRE , the subsequent exploration program
has delivered an MRE with significantly improved grade and a larger resource. This
confirms our belief that a potential underground bulk mining scenario is the most attractive
option at Fenelon, as it has the potential to deliver attractive economics with lower capex,
a smaller footprint and faster permitting process than a large open pit . We believe a
resource of this size, grade and zone thickness could be analogous to some of the large,
bulk-mineable deposits that are already being successfully mined in the Abitibi region
today. The updated MRE is a significant milestone as Wallbridge prepares to deliver a
preliminary economic assessment for Fenelon in Q2 2023.”
Attila Péntek, Wallbridge’s Vice President, Exploration added:
“Today’s updated mineral resource reflects the Company’s focused and effective drilling
and sampling program which has essentially repla ced over 800,000 lower grade ounces
with 1.3 million higher-grade ounces at Fenelon. This translated into significant increases
in gold grade at Fenelon, with an 85% increase in the grade of the Indicated resources
and an 84% increase in the grade of Inferred resources, compared to the 2021 Fenelon
maiden MRE. We also achieved positive results at Martiniere, where we increased the
resource ounces substantially, with a 26% increase in the Indicated category and a 146%
increase in the Inferred category. We continue to pursue value -generating growth, with
both deposits remaining open in multiple directions , and substantial potential for
discoveries along our extensive, underexplored land package. We look forward to carrying
our positive exploration momentum into 2023.”

Mineral Resource Estimation Methodology
The updated MRE for Fenelon is based on 1,350 recent and historic drill holes totaling
approximately 537,000 m, variably spaced from 20 to 200 m on the Gabbro,
Tabasco/Cayenne, Area 51 and Ripley/Reaper zones. This includes 917 drill holes totaling
approximately 460,000 m drilled by Wallbridge since 2016.
The updated MRE for Martiniere is based on 596 recent and historic drill holes totaling
over 169,000 m, variably spaced from 20 to 150 m on the Martiniere North, Martiniere
West, Martiniere Central, Bug Lake and Horsefly zones. A total of 54 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 MREs were prepared in Leapfrog Edge using
a sub-block model of 4m x 4m x 4m parent blocks. Gold grades were calculated using the
Inverse Distance squared interpolation method using hard boundaries for both deposits.
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 (2 m), and constraining volumes (Deswik optimized shapes
and Whittle optimized pit -shells). The reasonable prospect for an eventual economical
extraction will be further evaluated in the upcoming PEA which is expected in Q2 2023.

Notes:
1. The independent and qualified persons for the current Detour-Fenelon Gold Trend 2023 MRE are Carl Pelletier,
P.Geo.,Vincent Nadeau-Benoit, P.Geo., Simon Boudreau, P.Eng. and Marc R, Beauvais, P.Eng., of InnovExplo
Inc. The Detour-Fenelon Gold Trend 2023 MRE follows 2014 CIM Definition Standards and 2019 CIM MRMR
Best Practice Guidelines. The effective date of the Detour-Fenelon Gold Trend 2023 MRE is January 13, 2023.
2. These mineral resources are not mineral reserves as they do not have demonstrated economic viability.
3. The QPs are not aware of any known environmental, permitting, legal, title- related, taxation, sociopolitical or
marketing issues, or any other relevant issue, that could materially affect the potential development of mineral
resources other than those discussed in the Detour-Fenelon Gold Trend 2023 MRE.
4. For Fenelon, 112 high- grade zones and seven (7) low -grade envelopes were modelled in 3D to the true
thickness of the mineralization. Supported by measurements, a density value of 2.80 g/cm3 was applied to the
blocks inside the high-grade zones, and 2.81 g/cm3 was applied to the blocks inside the low-grade envelopes.
High-grade capping was done on raw assay data and established on a per-zone basis and ranges between 25
g/t and 100 g/t Au for the high- grade zones (except for the high-grade zones Chipotle and Cayenne 3 a high-
grade capping values of 330 g/t Au was applied) and ranges between 4 g/t and 10 g/t Au for the low -grade
envelopes. 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 . A minimum mining width of 2 metres w as used
for underground stope optimization.
5. For Martiniere, 75 high-grade zones and nine (9) low-grade envelopes were modelled in 3D to the true thickness
of the mineralization. Supported by measurements, a density value of 2.83 g/cm3 was applied to the blocks
inside the high- grade zones (except for the high- grade zones associated with massive sulfide intersections
where a value of 3.00 g/cm3 was applied), and 2.81 g/cm3 was applied to the blocks inside the low -grade
envelopes. High-grade capping was done on raw assay data and established on a per-zone basis and ranges
between 25 g/t and 100 g/t Au for the high-grade zones and ranges between 1 g/t and 6 g/t Au for the low-grade
envelopes. 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 . A minimum mining width of 2 metres was used
for underground stope optimization.
6. The criterion of reasonable prospects for eventual economic extraction has been met by having constraining
volumes applied to any blocks (potential surface and underground extraction scenario) using Whittle and DSO
and by the application of cut-off grades. The cut-off grade for the Fenelon deposit was calculated using a gold
price of US$1,600 per ounce; a CA/US exchange rate of 1.30; a refining cost of $5.00/t; a processing cost of
$18.15/t; a mining cost of $5.50/t (bedrock) or $2.15/t (overburden) for the surface portion, a mining cost of
$65.00/t for the underground portion and a G&A cost of $9.20/t. Values of metallurgical recovery of 95.0% and
royalty of 4.0% were applied during the cut -off grade calculation. The cut -off grade for the Martiniere deposit
was calculated using a gold price of US $1,600 per ounce; a CA/US exchange rate of 1.30; a refining cost of
$5.00/t; a processing cost of $18.15/t; a mining cost of $4.55/t (bedrock) or $2.15/t (overburden) for the surface
portion, a mining cost of $118.80/t for the underground portion using the long-hole mining method (LH), a mining
cost of $130.70/t for the underground portion using the cut and fill mining method (C & F), a G&A cost of $9.20/t
and a transport to process cost of $6.50/t. Values of metallurgical recovery of 96.0% and royalty of 2.0% were
applied during the cut-off grade calculation. The cut-off grades should be re-evaluated in light of future prevailing
market conditions (metal prices, exchange rate, mining cost, etc.).
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.
