Happy Creek Intercepts 1.18 m of 6.83% WO3 from 31.2 m DH Depth at the Fox Tungsten Project in British Columbia

(TheNewswire)

December 17, 2025, Vancouver, British Columbia –TheNewswire - Happy CreekMinerals Ltd. (TSX-V: HPY) (“Happy Creek” or the “Company”) ispleased to report assays from the 2025 drill program at the FoxTungsten Project in the South Cariboo district of British Columbia(the “Fox Project” or the “Project”).

Highlights

• Eighteen diamond core drill holes were completed at theFox Project for a total of 2,176 meters drilled during the period fromSeptember 5th to October 5th, 2025.  The drilling was focused on theexpansion of the tungsten resource at the Ridley Creek (RC), and BNzones  

• Drilling at the RC zone has defined continuity of andexpanded the calc silicate horizon to the southwest and is clearlyopen to the west beneath Deception Mountain.  Highlights at the RCzone include: 

  • 1.18 meters grading 6.83% WO3from 31.2 m downhole depth in holeF25-13 

  • 1.00 meters grading 2.22% WO3from 47.0 m downhole depth in holeF25-01 

  • 0.95 meters grading 1.11%% WO3from 36.5 m downhole depth in holeF25-02 

• Drilling at the northwest side of the BN Zoneintersected several calc silicate horizons that support a stackedlayer model with one horizon some 200 meters below surface. The 2025drilling clearly indicates the calc silicate horizons and associatedtungsten mineralization are open to the west and north beneathDeception Mountain and there remains potential for additional horizonsat depth.  Highlights at the BN zone include: 

  • In hole F25-16: 1.00 meters grading 0.88%WO from 105.0 m downhole depth and 1.65 metersgrading 0.57% WO3 from218.3 m downhole depth 

  • In hole F25-17: 2.50 meters grading 0.25%WO3 from 106.2 m downholedepth and2.00 meters grading 0.79%WO3 from 215.0 m downholedepth

Fox Project - 2025 ExplorationProgram

During the period from September 5 to October 5, 2025,Happy Creek completed 18 NQ diameter diamond core drill holes (total2,175.5 metres) at the Fox tungsten Project focused on resourceexpansion at the RC and BN zones.

RC Zone

At the RC zone, the tungsten mineralization is locatedalmost exclusively in the calc-silicate unit. This lithological unitintercalates with a biotite schist unit and monzogranite and alaskitesills are subparallel to cross-cutting these units.

The RC zone is currently approximately 400 metres by175 metres in dimension. It is a gently dipping to the west tabularbody approximately 5 metres to 25 metres in thickness with the top atsurface on the east and approximately 25-75 metres below surface tothe west.

2025 RC Zone Drilling

A total of 14 diamond core drillholes were completed atthe RC zone during the 2025 field season for a total of 1,304.5 metresdrilled and an average hole depth of approximately 92 metres (SeeTable 1).

The focus on the 2025 drill program at the RC zone wasto explore the extent of the calc silicate hosted tungstenmineralization mainly to the west and south and in-fill gaps on theeastern side. Most holes were drilled to the south where almost noprevious drilling was done and are well beyond the southern limit ofthe resource area. Previous exploration work done at this southernpart is mainly surface geology, rock sampling and limited handtrenching in 2025 that returned up to 2.6% WO3 over 0.30 metres. The drillingconfirmed geological continuity of the calc silicate from surface onthe east to approximately 50 metres in thickness westward and expandedit some 250 metres southward from the RC zone towards the BN zone. The2025 drilling clearly shows the calc silicate horizon continueswestward the entire length of the RC zone and is open beneathDeception Mountain.

BN Zone

The BN zone consists of three stacked calc silicatehorizons intercalated with biotite schist that are cut by varyingthicknesses of monzogranite, alaskite to aplite intrusive sills and/ordikes. The BN zone occurs adjacent the large Deception stock, atwo-mica monzogranite, and the intrusive sills are generally thickerthan at the RC zone.

The Middle horizon of the BN zone is currently the bestdefined and contains most of the current resource that isapproximately 20 to 80 metres below surface. Overall, thedrill-defined BN zone is approximately 300 metres by 350 metres indimension and outcrops to the east and dips west to northwest.Scheelite mineralization at the BN zone is mainlyassociated with the calc-silicate zones which can be either within theintrusive sills (endo-skarn) and in the surroundingcarbonate-sedimentary rocks altered to calc silicate(exo-skarn).

2025 BN Zone Drilling

A total of four diamond core drillholes (F25-15,F25-16, F25-17, F25-18) were completed at the BN zone during the 2025field season for a total of 871.0 metres drilled and an average holedepth of approximately 218 metres (See Table 1).

The 2025 drilling tested the potential for mineralizedcalc silicate horizons to extend to the northwest and at depth todemonstrate the resource expansion potential of the zone.

2018 Mineral Resource Estimate

In 2018, Happy Creek published a NI43-101 ResourceEstimate for the Fox Tungsten Project. The resource estimate includedan Indicated Resource of 582,400 tonnes at 0.826% WO3, all located within the RC Zone. The2018 NI43-101 Resource Estimate also included an Inferred Resource of565,400 tonnes at 1.231% WO3 located predominately at the BN Zone (453,000 @ 1.321WO3). (See Happy Creeknews release dated February 27, 2018 for full details,reference NI 43-101 Resource Update, Desautelsand Berndt, April 9, 2018).

Quality Assurance / Quality ControlProcedures

NQ size diamond drill core was split and sampled over intervalsranging from 0.38 metres to 2.35 metres and averaging approximately1.3 metres. Samples were shipped to, prepared, and analyzed at ALSCanada Ltd (ALS) in North Vancouver, British Columbia. ALS meets allrequirements of International Standards ISO/IEC 17025:2005 and ISO9001:2015 for analytical procedures. Samples are analyzed for tungstenusing ALS’s fusion method W-XRF10, and for trace elements byultra-trace aqua regia method ME-ICP41. Results for tungsten arepresented by ALS in % W. For its own reporting, the Company converts Wto WO3 (tungsten trioxide) by multiplying thereported W value 1.261 to obtain WO3, which isthe compound for which tungsten concentrate and prices are quoted. Inaddition to ALS internal laboratory quality assurance / qualitycontrol, Happy Creek implements an internal QA/QC program thatincludes the insertion of sample blanks, duplicates, and certifiedreference standards in the string of drill core samples.

On behalf of the Board of Directors,

“Stephen Gray”

President and Chief Executive Officer
