  Toronto, Ontario – July 2, 2025 – Wallbridge Mining Company Limited (TSX: WM, OTCQB:WLBMF) (“Wallbridge” or the “Company”) announced today the results for the remaining seven holes from its first phase of drilling (“Phase 1”) at its fully owned Martiniere gold project (“Martiniere”). These results include additional high-grade gold intercepts from extensions of three zones targeted along the Bug Lake “BL”) 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 14th 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.

  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 ("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 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.

  Wallbridge  prepares its disclosure in accordance with NI 43-101 which differs from  the requirements of the U.S. Securities and Exchange Commission (the "SEC"). Terms  relating to mineral properties, mineralization and estimates of mineral  reserves and mineral resources and economic studies used herein are  defined in accordance with NI 43-101 under the guidelines set out in CIM  Definition Standards on Mineral Resources and Mineral Reserves, adopted  by the Canadian Institute of Mining, Metallurgy and Petroleum Council  on May 19, 2014, as amended. NI 43-101 differs significantly from the  disclosure requirements of the SEC generally applicable to US companies.  As such, the information presented herein concerning mineral  properties, mineralization and estimates of mineral reserves and mineral  resources may not be comparable to similar information made public by  U.S. companies subject to the reporting and disclosure requirements  under the U.S. federal securities laws and the rules and regulations  thereunder. |
