WALLBRIDGE AND MIDLAND TO TEST
HIGH-PRIORITY GOLD TARGETS AT CASAULT
Toronto, Ontario – August 27, 2026 – Wallbridge Mining Company Limited (TSX:WM,
OTCQB:WLBMF) (“Wallbridge” or the “Company”) , in partnership with Midland Exploration Inc.
(“Midland”), is pleased to announce that field crews and a diamond drill rig have been mobilized to the
Casault gold property (“ Casault”) in preparation for the commencement of a 3,000 metre diamond
drilling campaign this week.
Highlights:
• Drilling program totalling approximately 3,000 metres in 10 to 12 drill holes;
• More than 15 newly recognized exploration targets generated from new structural and
geophysical interpretation, including the Vortex gold occurrence.
“We are very pleased to have our exploration team and drilling crews back in the field following the
approximately six -week interruption caused by regional wildfire activity,” said Brian Penny, CEO of
Wallbridge. “The team is eager to begin drilling at Casault to test the high -priority targets generated
through a comprehensive reinterpretation of field mapping and historic drilling and geophysical data
recently completed by our exploration team . Over the coming weeks, we will also resume the initial
ramp-up of infill drilling at Fenelon in preparation for a larger campaign beginning in the fourth quarter
to support the pre -feasibility study planned for completion in late 2027 or early 2028. With activities
restarting across our Detour-Fenelon trend property, we look forward to advancing both our near-term
development objectives at Fenelon and the potential for new gold discoverie s across our broader
property holdings, beginning with Casault.”
Diamond Drilling
The primary objective of the 2026 drilling campaign at Casault is to evaluate the potential for additional
gold discoveries along the Sunday Lake Deformation Zone (“SLDZ”) through first pass testing of newly
interpreted exploration targets and follow-up drilling at the Vortex gold occurrence.
Wallbridge has designed the planned 3,000 metre drill program consisting of10 to 12-holes, to evaluate
several high -priority gold targets identified through a comprehensive reinterpretation of historical
geophysical and drilling data, combined with recent geological mapping and surface sampling. Drilling
will initially focus on a series of high -priority targets located where the east -west trending SLDZ is
intersected by northwest -trending cross -faults and subsidiary shear zones, which are commonly
intruded by dikes ranging from mafic to intermediate and felsic compositions. These areas are
considered favourable sites for gold mineralization and reflect the structural setting that controls gold
mineralization at Wallbridge’s Fenelon and Martiniere gold projects, as well as Agnico Eagle's Detour
Lake gold mine. The drilling campaign will follow a results-driven approach, beginning with several holes
at the Vortex occurrence followed by first pass tests at priority targets elsewhere on the Casault
property.

Drilling by Midland in 2017 led to the discovery of the Vortex Zone, a new showing of shallow syenite -
associated gold mineralization hosted within a series of sub -parallel steeply dipping shear structures
developed along a transitional contact between gabbroic rocks to the north and mafic volcanic rocks to
the south. Gold mineralization has been traced within a corridor approximately 50 metres wide and
1,200 metres along strike, remaining open to the east, west, and at depth. Significant intercepts from
the discovery program include:
▪ 1.30 g/t Au over 23.5 m including 3.46 g/t Au over 6.0 m and 23.6 g/t over 0.5 m (CAS-17-095)
▪ 1.38 g/t Au over 26.5 m including 7.87 g/t Au over 2.2 m and 14.55 g/t Au over 0.8 m (CAS-17-096)
* For additional details see Midland news releases dated September 21, 2017, January 30, 2018, July 5, 2018.
A recent reinterpretation of historical drilling and high -resolution airborne geophysical data by
Wallbridge has identified a potential eastward extension of the shear -hosted gold system that could
increase the strike length of the Vortex Zone by approxima tely 1,000 metres. The drilling planned for
Vortex will comprise 5 to 6 drill holes totaling approximately 1,500 to 1,750 metres, designed to test the
interpreted eastern extension while also evaluating the continuity of gold mineralization within the main
Vortex Zone.
The second area to be tested by Wallbridge is the C2 target, located approximately 4 kilometres
southwest of the Vortex Zone. C2 is a compelling undrilled target situated at the intersection of the SLDZ
and a northwest -trending cross -fault, adjacent to the contact between a large intrusive stock and
surrounding mafic volcanic and sedimentary rocks. The coincidence of these favourable structural and
lithological features represents an attractive setting for gold mineralization. Wallbridge plans to complete
an initial 3 to 4 hole campaign totaling approximately 750 to 1,000 metres to evaluate the C2 target.
Additional high-priority targets under consideration for this year’s drilling campaign include the
intersection of the SLDZ and the northwest -trending Fontina cross-fault, as well as untested induced
polarization (“IP”) conductivity anomalies along the Lac du Doigt fault zone, a major shear structure
controlling gold mineralization at Wallbridge’s Martiniere deposit located approximately mid -way
between the Vortex and Fontina targets. Depending on final target prioritization, Wallbridge anticipates
drilling one or both target areas with 3 to 4 holes totaling approximately 500 to 750 metres.
Casault Gold Property
The Casault property, comprising three claim blocks totaling 177 square kilometres, is located
approximately 110 kilometres west of the town of Matagami. The property is strategically positioned
along a 20 kilometre section of the SLDZ, a regionally extensive gold -bearing fault system that hosts
Agnico Eagle's Detour Lake Mine located approximately 35 kilometres to the west, and Wallbridge’s
Martiniere and Fenelon deposits, located 14 and 42 kilometres to the north east and east respectively.
Wallbridge holds an option to earn up to a 65% interest in Casault through staged exploration
expenditures and other earn-in commitments to Midland (see Wallbridge news release dated June 18,
2020).
The Vortex gold zone is characterized by the presence of monzonitic alkaline intrusions associated with
predominantly hematite, magnetite, carbonate, and albite alteration as well as disseminated pyrite
mineralization. These alkaline intrusions commonly oc cur within 1 to 2 kilometres of the SLDZ along

contacts and within a sequence of highly deformed mafic volcanic host units. The Lower Detour gold
deposit (Zone 58N), located 6 kilometres south of the Detour Lake mine and approximately 40
kilometres southwest of Vortex, is a high-grade gold deposit that is also described as associated with
alkaline intrusions. This type of gold mineralization is known as “syenite-associated disseminated gold”.
Several very significant gold deposits in the southern Abitibi belong to this category, namely Canadian
Malartic, Young-Davidson and Holt-McDermott (Robert, 2001a).

Cautionary Statement
Mineralization occurring on the Fenelon Gold and Martiniere gold projects held by Wallbridge, and at the
Detour Lake mine held by Agnico Eagle Mines Limited, is not necessarily indicative of mineralization that
may be found on the Casault property held by Midland.
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 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 the metallic screen fire assay method. Act Labs operates under a Quality Management System
that conforms to the requirements of ISO/IEC 17025.
