Wallbridge Expands Ripley Zone,

Mobilizes Drill to Further Test Gold Potential along Sunday Lake

Deformation Zone

Toronto, Ontario – February 28, 2023 – Wallbridge Mining Company Limited (TSX:WM,

OTCQX:WLBMF) (“Wallbridge” or the “Company”) is pleased to report additional results from its

2022 drilling program at the Company’s 100%-owned Fenelon gold project (“Fenelon”) that have

expanded the satellite Ripley Zone towards the southwest. In addition, new prospective targets have

been identified along the Sunday Lake Deformation Zone (“SLDZ”).

Following a two- month pause in drilling, two rigs were deployed in early February to commence

exploration drilling in the vicinity of the Fenelon gold deposit; a third drill has now been mobilized to

test newly identified gold targets along the SLDZ.

“Building on the multi -million-ounce resource we have already established at Fenelon and

Martiniere, our 2023 exploration program is targeting the discovery of new gold zones on the

Company’s highly prospective Detour -Fenelon Gold Trend land package,” said Attila Péntek,

Wallbridge’s Vice President, Exploration. “Positive drill results at Ripley, a satellite zone located

one kilometre south of the main Fenelon deposit, reinforce the potential for further discoveries

along the SLDZ, which remains largely untested towards the east and west. The upcoming drill

program will focus on testing extensions of the main host rocks and structures that control

known gold mineralized trends in this region using large-spaced drill step-outs.”

Results reported today (Table 1) successfully expanded the Ripley zone to the southwest and

support the potential for further gold mineralization along the SLDZ. These new drill results and

geological interpretation indicate potential folding of the host rocks immediately south of the Ripley

Zone, providing a high-priority drill target.

About the Ripley Zone

The Ripley Zone straddles the northern contact of the SLDZ, in contrast to the main Fenelon deposit,

which is located along the Jeremie Fault, a secondary splay of the S LDZ (see Figure 1). Agnico’s

Detour Lake Mine is also located along the northern edge of the SLDZ, emphasizing the importance

of this structural horizon.

Sporadic gold mineralization was first discovered at Ripley in the summer of 2019, following up on

the discovery of the Fenelon Area 51 and Tabasco/Cayenne Zones. The drilling program conducted

by Wallbridge in 2021-22 further delineated the mineralized footprint of the Ripley Zone. Systematic

drilling also revealed the continuity and pervasive nature of the gold mineralization.

The gold-bearing system at Ripley has now been traced for a lateral distance of over 750 metres,

and has only been tested down to a vertical depth of approximately 500 metres. Exploration potential

remains open in most directions, both laterally and at depth.

Important geological observations at Ripley also include the spatial proximity of gold mineralization

with Timiskaming-type sedimentary rocks. In the Southern Abitibi, such units are known to provide

excellent markers for structures that acted as mineralizing gold fluid pathways (e.g., Timmins and

Kirkland Lake gold camps) . This new information will be useful to define additional prospective

targets regionally.

2023 Drill Program

Very limited historic drill testing was conducted along the SLDZ outside a 1.5 kilometre strike length

corridor centered on the Ripley Zone (see Figure 2). Several targets were identified within a few

kilometres of the Ripley Zone that, based on geology and geophysics, are interpreted to be favorable

for the deposition of gold mineralization.

Wallbridge’s 2023 drilling strategy will aim to evaluate the extensions of known mineralized zones

using large -spaced step -outs. In addition, exploration drilling along the SLDZ will focus on

conceptual targets, including the potential folding of the Jeremie diorite intrusion immediately south

of the Ripley Zone.

The results reported in today’s press release are from 14 drill holes completed in 2022. 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/.

About Wallbridge Mining

Wallbridge is focused on creating value through the exploration and sustainable development of

gold projects along the Det our-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 Qué bec’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 approximate 830 km 2 exploration land package

controlled by Wallbridge. The Company believes that these two deposits have good potential for

economic developme nt, 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.
