Wallbridge Exploration Drilling Continues to Deliver Significant Gold
Grades from Dragonfly Zone Along Bug Lake Deformation Corridor
Toronto, Ontario – September 29, 2025 – Wallbridge Mining Company Limited (TSX: WM,
OTCQB:WLBMF) (“Wallbridge” or the “Company”) announced today the results for the first six holes
from the second phase of drilling (“Phase 2”) at its 100% owned Martiniere gold project (“Martiniere”).
These results further confirm the geologic continuity of the Dragonfly fault system as a series of sub -
parallel mineralized structures, several of which host multiple high-grade gold intercepts ranging from
0.5 to over 5 metres in down-hole length.
HIGHLIGHTS*
MR-25-128-W1 5.99 g/t Au over 4.7 m including 42.70 g/t Au over 0.5 m
MR-25-129B 6.13 g/t Au over 3.4 m
13.24 g/t Au over 2.0 m
MR-25-130A 4.30 g/t Au over 3.6 m including 11.30 g/t Au over 0.5 m
11.12 g/t Au over 2.0 m including 19.70 g/t Au over 1.0 m
2.57 g/t Au over 3.3 m including 7.66 g/t Au over 0.6 m
MR-25-131 6.79 g/t Au over 1.0 m
14.58 g/t Au over 3.3 m including 45.40 g/t Au over 0.9 m
* True widths are estimated to be 60-90% of the reported core length intervals.
“These latest drilling results continue to demonstrate the potential for a more extensive mineralized gold
system at Martiniere than is currently outlined in the existing mineral resource estimate,” commented
Brian W. Penny, CEO. “Phase 2 drilling, building on the success of Phase 1 completed in May, has been
strategically focused on testing down -dip extensions of known gold zones. Current exploration is
concentrated on the Dragonfly and Horsefly areas, where results to date suggest significant potential to
expand the mineralized footprint and support future resource growth at Martiniere ,” continued Mr.
Penny.
Martiniere 2025 Drilling Program
The second phase of the 2025 Martiniere diamond drilling program began in mid-July (see Wallbridge
news release dated July 17, 2025). This release reports results from the first six Phase 2 holes. Including
Phase 1 drilling results (see June 2, 2025 and July 2, 2025 news releases) and the results presented in
this news release, the Company has completed 22 holes and 2 hole extensions totaling 10,840 metres.
Encouraged by continued positive results along the Bug Lake corridor, the Company has expanded the
program beyond its original 10,000 –15,000 metre plan, with drilling scheduled to continue into mid -
October before winter demobilization.
Five of the Phase 2 holes reported here tested a 400 -metre westerly strike projection of the Dragonfly
zone toward the Bug Lake North and Horsefly zones. Drilling was completed along three north –south
section lines spaced 150 metres apart, with hole depths extending to approximately 600 to 850 metres
below surface. These holes were drilled to follow on strong results from Phase 1 holes MR-25-111, MR-

25-112, MR-25-121, and MR-25-123. A table of summarized gold assay intervals and links to supporting
maps and cross-sections are provided below.
• MR-25-129B (Section B -B’), collared 250 metres east of the Bug Lake North underground
resource and 150 metres down-dip of Phase 1 hole MR-25-121, intersected multiple mineralized
structures with intercepts that included 6.13 g/t Au over 3.4 metres, 2.31 g/t Au over 5.5 metres
and 13.24 g/t Au over 2.0 metres.
• MR-25-130A (Section C-C’), 150 metres east of Section B-B’ and 150 metres down-dip of Phase
1 hole MR-25-123, returned three discrete gold-bearing structures with intercepts of 4.30 g/t Au
over 3.6 metres, 11.12 g/t Au over 2.0 metres and 2.57 g/t Au over 3.3 metres.
• MR-25-128 and wedge MR-25-128W1, along with MR-25-131 (Section D-D’), tested a 250 metre
down-dip projection of mineralization intercepted in Phase 1 hole MR-25-111. Results included
multiple gold-bearing structures, highlighted by intercepts of 5.99 g/t Au over 4.7 metres and
14.58 g/t Au over 3.3 metres.
The sixth Phase 2 drill hole, MR -25-127, drilled to test a potential down -dip extension of gold
mineralization along the Martiniere North zone, did not return significant gold grades above 1 g/t Au.
However, the hole intersected three shear deformation zones characterized by mode rate to strong
silicification and pyritic sulfide mineralization over widths of 5 to 6 meters down -hole. These alteration
and mineralization styles are the key structural controls known to host gold at Martiniere, and their
presence in MR-25-127 may be used as prospective vectors for follow-up drilling in the future.
The Phase 2 drilling campaign at Martiniere remains ongoing at the time of this news release. Assay
results are pending for an additional 10 holes totaling 4,850 meters, and the Company plans to drill
another 4 to 5 holes to complete the program. By the end of Phase 2 in October, Wallbridge expects to
have completed approximately 18,000 meters of drilling at Martiniere during 2025.
To date, exploration drilling along the Bug Lake deformation corridor has intercepted significant gold
mineralization across an area measuring approximately 2,000 by 800 metres and to a vertical depth of
800 metres from surface. Mineralization along the BL corridor remains open in both directions along
strike and down dip. Importantly, deeper intercepts from historic drilling — including 6.4 metres grading
4.32 g/t Au in BLD -16-01 and 1.0 metre grading 6.18 g/t Au in MDE -17-289 — demonstrate that the
Martiniere system remains open at depth to at least 850 metres below surface. Gold mineralization at
Martiniere is hosted within mafic volcanics and younger felsic porphyry dykes, occurring along discrete
shear and breccia zones associated with pyritic silica flooding, quartz -carbonate veining, and silica -
sericite alteration.

2 Asterisk * denotes visible gold (VG) observed in drill core.
3 Reported drill hole depths and interval lengths have been rounded to the nearest 0.1 metres. As a result, interval lengths may vary
slightly from differences calculated directly from drill hole depths reported here.
4 True widths are estimated to be 60-90% of the reported core length intervals.

Quality Assurance / Quality Control
Wallbridge maintains a Quality Assurance/Quality Control ("QA/QC") program for all its exploration projects
using industry best practices. Key elements of the QA/QC program include verifiable chain of custody for
samples, regular insertion of blanks and certified reference materials, and completion of secondary check
analyses performed at a separate independent accredited laboratory. Drill core is halved , sampled, and
shipped in sealed bags to Activation Laboratories Ltd. (ActLabs) in Val d’Or, Quebec , where samples are
routinely analysed via fire assay with atomic absorption spectroscopy (‘AAS’) finish methods. For greater
precision and accuracy, samples assaying 10 g/t Au or greater are re-distributed to other ActLabs facilities
where they are re-assayed via metallic screen fire assay or fire assay/gravimetric finish, depending on the
amount of sample material remaining available. Samples containing visible gold are routinely submitted
directly for analysis by metallic screen fire assay method. Activation Laboratories Ltd. operates under a
Quality Management System that conforms to the requirements of ISO/IEC 17025.
