Wallbridge Phase 1 Drilling at Martiniere Encounters Multiple High-Grade Vein Structures and Confirms Grade Continuity in Known Mineralized Zones

TORONTO, July 31, 2024 - Wallbridge Mining Company Ltd. (TSX: WM, OTCQB:WLBMF) ("Wallbridge" or the "Company") today announced that assay results from the 9,000 metre Phase 1 drilling program at its 100% owned Martiniere gold project ("Martiniere") confirm the presence of high-grade gold mineralization in multiple sulfide vein assemblages and further define the continuity of mineralization and gold grades at the Bug Lake North, Bug Lake South and Martiniere West zones.

Highlights

• Intersected multiple zones of pyritic sulfide veining hosting high-grade gold mineralization including:
  • 44.63 g/t Au over 1.1 metres, 8.52 g/t Au over 1.5 metres, and 27.48 g/t Au over 1.0 metre in hole MR-24-066 testing the Bug Lake North zone.
  • 8.40 g/t Au over 1.5 metres in hole MR-24-070, as well as 9.47 g/t Au over 0.9 metres and 4.62 g/t Au over 2.4 metres in hole MR-24-071A testing the Bug Lake South zone.
  • 3.14 g/t Au over 3.4 metres in hole MR-24-086 testing the Martiniere West zone.
• Confirmed gold distribution and grade continuity across broad widths in the Bug Lake North, Bug Lake South, and Martiniere West zones:
  • 24.3 metres averaging 1.62 g/t Au in hole MR-24-068 including 1.6 metres averaging 13.53 g/t Au at Bug Lake North.
  • 21.1 metres averaging 2.15 g/t Au in hole MR-24-085 at Bug Lake South.
    
  • 6.5 metres averaging 2.87 g/t Au in hole MR-24-074 at Martiniere West.

Wallbridge's CEO Brian Penny remarked: "The successful completion of our Martiniere Phase 1 drilling program marks an important milestone in advancing the project. With geotechnical characterization studies and metallurgical testing well underway, our focus now shifts to exploring extensions along the known gold-bearing trends toward newly identified satellite targets, including the Dragonfly and Horsefly zones. These targets present excellent potential for expanding the Martiniere resource base. We are excited about the significant upside potential at Martiniere and Fenelon and look forward to sharing later this year the results of the ongoing metallurgical and geotechnical rock mass characterization studies."

A 185-kilogram composite sample has been collected from the Phase 1 drill program and sent to SGS Lakefield Mineral Services for metallurgical tests, including gold recoveries. In addition, approximately 4,550 metres of drilling was surveyed using a downhole optical and acoustic televiewer probe for a geotechnical rock mass characterization study being carried out by WSP Consulting.

The Company is also commencing a 6,000 metre Phase 2 Martiniere drilling program designed to test potential extensions of the mineralized gold trends identified through recently completed re-interpretation of deposit geology and mineralization controls. The re-interpretation was completed by the Company's exploration team working in collaboration with independent consultants specializing in structural geology, mineral deposit modeling and resource estimation.

Additional highlights from the 2024 Martiniere Phase 1 drilling program are provided in the table of summarized assay highlights below. For more information, including a drill hole location map and representative cross-sections, please refer to the link provided here:

Martiniere is a key project on the Company's 830 square kilometre Detour-Fenelon Trend property package located in Northern Abitibi, Quebec, 30 kilometres west of the Company's flagship Fenelon gold project and 50 kilometres east of Canada's largest gold mine, Agnico Eagle's Detour Lake gold mine. Exploration and resource delineation drilling completed at Martiniere has so far intercepted multiple zones of vein-hosted gold mineralization over an approximate 1 kilometre by 500 metre area along the northwest-southeast trending Bug Lake structural corridor, and over an approximate 1.5 kilometre by 250 metre area along the northeast-southwest trending Martiniere West and Central corridor. Both the Bug Lake and Martiniere corridors remain open laterally and at depth below the current 450 to 500 metre vertical extent of drilling completed to date. The Company looks forward to providing the results of its Phase 2 exploration drilling program which it anticipates will be completed by the end of the third quarter.

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 and shipped in sealed bags to SGS in Val d'Or, Quebec where they are re-distributed to other SGS laboratory facilities according to the analytical method being requested by Walbridge. Gold analyses are routinely performed via fire assay with ICP-OES finish methods. For greater precision and accuracy, samples assaying 10 g/t Au or greater are re-assayed via metallic screen fire assay method or fire assay/gravimetric finish, depending on the amount of sample material remaining available. Samples containing visible gold are submitted directly for analysis by metallic screen fire assay method.

SGS Natural Resources analytical laboratories operate under a Quality Management System that conforms to the requirements of ISO/IEC 17025. All of SGS' Canadian analytical sites are accredited by the Standards Council of Canada (SCC) for specific mineral tests listed on the scope of accreditation to the ISO/IEC 17025 standard. ISO/IEC 17025 addresses both the quality management system and the technical aspects of operating a testing laboratory. Physical sample preparation involving accredited test methods as listed on the scope of accreditation may be performed at other sites listed on the SGS Canada Inc - Natural Resources - Minerals group accreditation or at offsite sample preparation laboratories that are monitored regularly for quality control and quality assurance practices, including SGS Canada Inc, Garson, SGS Canada Inc, Val d'Or and SGS Canada Inc, Grand Falls-Windsor.
