Wallbridge Mining Company Limited Reports Initial Results from 2026 Martiniere Drill Program Expanding Mineralization Along Dragonfly Corridor
Wallbridge Mining Company Limited announced the results for the first two holes completed as part of its 2026 Phase 1 drilling campaign at its 100% owned Martiniere gold project. The Phase 1 campaign is focused on the Dragonfly zone which forms the core of the Bug Lake deformation corridor and hosts the majority of the Martiniere mineral resource. MR-26-141 intersected a 2.8 metre shear-hosted interval grading 2.2 g/t Au at a down-hole depth of 68.5 metres. MR-26-141A intersected several narrow mineralized intervals, including 5.22 g/t Au over 1.3 metres along the sheared contact between a felsic porphyry dike and a pillowed basalt unit. Additional lower grade gold mineralization was intersected along the sheared margins of multiple porphyry dikes emplaced along the Dragonfly shear corridor. MR-26-142 intersected a series of sub-parallel mineralized structures, returning intervals including 2.01 g/t Au over 12.8 metres, 3.11 g/t Au over 18.4 metres, 3.75 g/t Au over 4.8 metres, 4.53 g/t Au over 13.5 metres, and 3.84 g/t Au over 3.0 metres. The majority of the defined resource area at Martiniere is hosted along the Bug Lake deformation corridor, a broad structural corridor comprising a series of northwest-striking, southwest-dipping shear zones spatially associated with felsic intrusive dikes developed within a large drag-fold structure adjacent to the regional-scale Lac du Doigt fault. Since early 2025, exploration drilling targeting the geologic continuity of the broader mineralized system has intersected significant gold mineralization over an area measuring approximately 2,000 metres along strike, by 800 metres in width, and to a vertical depth of at least 800 metres below surface. The system remains open to continued expansion laterally to the southeast and north, as well as at depth. The Martiniere mineral resource (published March 27, 2025) is estimated to contain 346,000 ounces of gold averaging 2.29 g/t Au in the Indicated category and 387,000 ounces of gold averaging 3.11 g/t Au in the Inferred category. Gold mineralization at Martiniere is primarily hosted within mafic volcanic rocks and younger felsic porphyry dikes, occurring within discrete shear and breccia zones characterized by pyritic silica flooding, quartz-carbonate veining, and silica-sericite alteration. Mineralization is commonly concentrated along sheared intrusive contacts and within zones of increased deformation throughout the broader Bug Lake deformation corridor. A table of gold assay highlights is provided below: MR-26-141: 68.5-71.3m, 2.8m, 2.20 g/t Au; MR-26-141A: 259.6-260.9m, 1.3m, 5.22 g/t Au; MR-26-142: 404.0-416.8m, 12.8m, 2.01 g/t Au; 469.1-487.5m, 18.4m, 3.11 g/t Au; 496.5-501.3m, 4.8m, 3.75 g/t Au; 560.5-574.0m, 13.5m, 4.53 g/t Au; 614.0-617.0m, 3.0m, 3.84 g/t Au. Highlighted assay composites have been selected based on a combination of criteria, including observable mineralization and/or having a Metal Factor >5 gmm (MF = Au g/t Interval length), and/or a minimum interval length of 1.5 metres. Asterisk * denotes visible gold (VG) observed in drill core. 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. True widths are estimated to be 70-90% of the reported core length intervals. Wallbridge maintains a Quality Assurance/Quality Control 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. 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 metallic screen fire assay method. Activation Laboratories Ltd. operates under a Quality Management System that conforms to the requirements of ISO/IEC 17025.
