Wallbridge Mining Company Limited (TSX: WM) (OTCQB:WLBMF) announced the results for the remaining seven holes from its first phase of drilling (“Phase 1”) at its fully owned Martiniere gold project. These results include additional high-grade gold intercepts from extensions of three zones targeted along the Bug Lake deformation corridor.

Highlights:

True widths are estimated to be 60-90% of the reported core length intervals.

“The final results of our Phase 1 drilling program reinforce our conviction in the growth potential of the Martiniere gold system, which we believe extends well beyond the currently defined mineral resource,” commented Brian W. Penny, CEO. “Our exploration team is now using these encouraging results, together with insights gained from the 2024 exploration program, and the updated mineral resource model to plan the next phase of drilling. Phase II is scheduled to begin later this month, and the Company is excited to continue to advance this project and unlocking its value,” concluded Mr. Penny.

Martiniere 2025 Drilling Program

The first phase of Company’s 2025 Martiniere diamond drilling program was completed on May 14^th and consisted of 16 diamond drill holes plus two hole extensions, totaling 7,225 metres (see Wallbridge news release dated June 2, 2025).   All final results for the Phase 1 program have now been received, including results for the 7 most recent holes, which are reported in this news release. During 2025, the Company plans to complete a total of 10,000 to 15,000 metres of drilling at Martiniere, with Phase 2 drilling scheduled to commence in July.

At Dragonfly, drill hole MR-25-123, along with previously reported holes MR-25-111, MR-25-112, and MR-25-121, returned multiple high-grade gold intercepts within a 400-metre-wide gap between the currently defined mineral resources at Dragonfly to the east and Bug Lake North and Martiniere North to the west. These intercepts begin at a depth of 250 metres and extend to 700 metres from surface, remaining open down plunge and along strike to the southeast. Similarly, drill hole MR-25-122 and previously-reported hole MR-25-117 encountered multiple structures hosting significant gold grades approximately 150 to 200 metres to the southeast of the currently defined mineral resource. Notably, drill hole MR-25-116, reported previously, returned a 4.0 metre intercept grading 18.54 g/t Au, approximately 150 to 200 metres below and lateral to the mid-portion of the Dragonfly gold resource, providing further evidence that the Dragonfly zone remains open to further expansion with depth.

Drilling conducted 500 metres to the south of the Dragonfly zone, aimed at evaluating the broader potential of the Bug Lake South zone, yielded encouraging results. Drill hole MR-25-119 returned 3.27 g/t Au over 1.1 metres, along with several additional intervals of weak to moderately anomalous gold grades.

At Horsefly, drill hole MR-25-125 and a previously-reported extension of hole MR-24-100 provide further confirmation of additional near-surface gold mineralization extending beyond the currently defined gold resource towards the Lac-Du-Doigt fault zone, located approximately 150 metres to the north. Drilling in this area has encountered a series of structures that host gold mineralization at depths ranging from 75 to 300 metres below surface. Notable results include 6.71 g/t Au over 14.4 metres in the deeper extension of hole MR-25-100 and 23.38 g/t Au over 2.0 metres in hole MR-25-125. Approximately 200 metres to the northwest of the Horsefly resource, drill hole MR-25-124 intersected a structure grading 6.83 g/t Au over 1.9 metres, along with two other intervals that show anomalous gold grades near the Lac-Du-Doigt fault zone.

To the north of the Lac-Du-Doigt fault in the Martiniere Northeast area, two widely spaced step-out holes were drilled to follow up on the positive results from hole MR-25-115, which returned a 3.0 metre intercept grading 7.27 g/t Au (reported previously). Drill hole MR-25-120, drilled 500 metres to the east, intercepted five mineralized structures ranging from 3 to 14 metres in length, including a 0.22 g/t Au over 2.5 metres, and 0.10 g/t Au over 2.3 metres. Similarly, hole MR-25-126, drilled 150 metres east of MR-25-115, intercepted several mineralized structures hosting weak to moderately anomalous gold grades. These included 0.39 g/t Au over 4.2 metres, 0.56 g/t over 1.5 metres and 0.25 g/t Au over 1.0 metre. Despite the lower grades returned from these two recent holes, the Martiniere Northeast area shows good potential for a new discovery, given the frequent occurrence of multiple gold-bearing structures distributed over a broad area that had not been drill tested prior to 2025.

As of now, exploration drilling along the Bug Lake corridor has identified gold mineralization across an area approximately 1,500 by 700 metres, extending to an average vertical depth of 350 to 400 metres below surface. Deeper intercepts from historic drill holes BLD-16-01, which intersected 6.4 metres averaging 4.32 g/t Au, and MDE-17-289, which intersected 1.0 metre grading 6.18 g/t Au, indicate the Martiniere gold system remains open to at least 800 to 900 metres vertical depth from surface. Gold mineralization at Martiniere occurs in close association with pyritic silica-sericite alteration, and quartz-carbonate veining, occurring along discrete fault and shear structures hosted by mafic volcanics and younger felsic porphyry dykes.

Martiniere Gold Project: Phase 1 2025 Drill Assay Summary and Drill Hole Location Information

The Martiniere project is a key component of 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 1.5 kilometre by 700 metre area along the northwest-southeast trending Bug Lake Zone, and over an approximate 1.5 kilometre by 250 metre area along the northeast-southwest trending Martiniere West and Central corridor.

Quality Assurance / Quality Control

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 and shipped in sealed bags to Activation Laboratories Ltd. (ActLabs) in Val d’Or, Quebec, where they are routinely analysed via fire assay with 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 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.
