Belmont Enhances Geological Understanding at Come By Chance Following Completion of 2025 Drill Program

(TheNewswire)

Vancouver, B.C. — TheNewswire– December 17, 2025 — Belmont Resources Inc.(TSX-V: BEA; FSE: L3L2) (“Belmont” or the “Company”) ispleased to report the completion of its 2025 diamond drilling programat the Come By Chance (“CBC”) Copper-Gold Project near GrandForks, British Columbia.

Belmont completed five drill holes across the centralstructural and geophysical corridor, collecting important newgeological information that builds on the Company’s 2022 drillresults.
While the program did not intersect economic mineralization, itsuccessfully achieved the geological understanding of the system,particularly in relation to structure, alteration, and magneticfeatures.

2025 Program: Advancing theGeological Model

The 2025 drilling followed up on earlier work andfocused on evaluating key geological and geophysical targets along the1.5-km CBC corridor.

The program delivered:

• Expanded geological knowledge across multiple targetareas 

• New structural, alteration, and lithologicalinformation 

• Improved magnetic susceptibility and oriented-coremapping 

• Stronger integration between drilling and surfacegeophysical data (IP, resistivity, magnetics) 

These results enhance the Company’s geological modeland provide an improved foundation for ongoing explorationevaluation.

Key Observations from the 2025 DrillProgram

Geology & Alteration

Drilling intersected volcanic and intrusive rockstypical of the Greenwood District.
Zones of weak to moderate alteration—chlorite, epidote, silica, andcarbonate—were logged in several holes, offering insight into fluidpathways.

Sulphide Occurrence

Trace pyrite and very minor chalcopyrite were noted,mainly in small veinlets or scattered grains.
These sulphides are non-economic but may help map mineralizing fluidsand structural trends.

Magnetic & StructuralMapping

Magnetic susceptibility data and logging oforiented-core measurements provided new detail on:

• Fault and vein orientations 

• Local deformation 

• Magnetite-bearing intervals 

These observations further refine structuralinterpretations across the corridor.

Geochemistry

Assay results returned low and discontinuous copper,gold, and pathfinder element values. This could be a potentialindicator for drilling in a peripheral part of a broad hydrothermalsystem.

Project Significance

Although economic mineralization was not encountered,the 2025 program:

• Strengthened the structural and geologicalunderstanding of the property 

• Added new data to calibrate surface geophysicalmodels 

• Helped map alteration 

• Advanced the overall interpretation of the CBCsystem 

The new information represents progress insystematically exploring a large, complex geological environmentwithin an historic mining district.

About the Come By ChanceProject

The 100 %-owned CBC Copper-Gold Project, located within the historicGreenwood Mining Camp of southern B.C., hosts a large magnetic-lowfeature coincident with IP chargeability and resistivity anomaliestypical of porphyry systems. The property lies within the prolificBoundary District, which contains multiple alkalic and calc-alkalicporphyry centres.
