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

Highlights

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

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

  • 1.18 meters grading 6.83% WO3 from 31.2 m downhole depth in hole F25-13

  • 1.00 meters grading 2.22% WO3 from 47.0 m downhole depth in hole F25-01

  • 0.95 meters grading 1.11%% WO3 from 36.5 m downhole depth in hole F25-02

• Drilling at the northwest side of the BN Zone intersected several calc silicate horizons that support a stacked layer model with one horizon some 200 meters below surface. The 2025 drilling clearly indicates the calc silicate horizons and associated tungsten mineralization are open to the west and north beneath Deception Mountain and there remains potential for additional horizons at 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 meters grading 0.57% WO3 from 218.3 m downhole depth

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

Fox Project - 2025 Exploration Program

During the period from September 5 to October 5, 2025, Happy Creek completed 18 NQ diameter diamond core drill holes (total 2,175.5 metres) at the Fox tungsten Project focused on resource expansion at the RC and BN zones.

RC Zone

At the RC zone, the tungsten mineralization is located almost exclusively in the calc-silicate unit. This lithological unit intercalates with a biotite schist unit and monzogranite and alaskite sills are subparallel to cross-cutting these units.

The RC zone is currently approximately 400 metres by 175 metres in dimension. It is a gently dipping to the west tabular body approximately 5 metres to 25 metres in thickness with the top at surface on the east and approximately 25-75 metres below surface to the west.

2025 RC Zone Drilling

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

The focus on the 2025 drill program at the RC zone was to explore the extent of the calc silicate hosted tungsten mineralization mainly to the west and south and in-fill gaps on the eastern side. Most holes were drilled to the south where almost no previous drilling was done and are well beyond the southern limit of the resource area. Previous exploration work done at this southern part is mainly surface geology, rock sampling and limited hand trenching in 2025 that returned up to 2.6% WO3 over 0.30 metres. The drilling confirmed geological continuity of the calc silicate from surface on the east to approximately 50 metres in thickness westward and expanded it some 250 metres southward from the RC zone towards the BN zone. The 2025 drilling clearly shows the calc silicate horizon continues westward the entire length of the RC zone and is open beneath Deception Mountain.

BN Zone

The BN zone consists of three stacked calc silicate horizons intercalated with biotite schist that are cut by varying thicknesses of monzogranite, alaskite to aplite intrusive sills and/or dikes. The BN zone occurs adjacent the large Deception stock, a two-mica monzogranite, and the intrusive sills are generally thicker than at the RC zone.

The Middle horizon of the BN zone is currently the best defined and contains most of the current resource that is approximately 20 to 80 metres below surface. Overall, the drill-defined BN zone is approximately 300 metres by 350 metres in dimension and outcrops to the east and dips west to northwest. Scheelite mineralization at the BN zone is mainly associated with the calc-silicate zones which can be either within the intrusive sills (endo-skarn) and in the surrounding carbonate-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 2025 field season for a total of 871.0 metres drilled and an average hole depth of approximately 218 metres (See Table 1).

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

2018 Mineral Resource Estimate

In 2018, Happy Creek published a NI43-101 Resource Estimate for the Fox Tungsten Project. The resource estimate included an Indicated Resource of 582,400 tonnes at 0.826% WO3, all located within the RC Zone. The 2018 NI43-101 Resource Estimate also included an Inferred Resource of 565,400 tonnes at 1.231% WO3 located predominately at the BN Zone (453,000 @ 1.321 WO3). (See Happy Creek news release dated February 27, 2018 for full details, reference NI 43-101 Resource Update, Desautels and Berndt, April 9, 2018).

For full details of the 2018 Fox Project Mineral Resource see the report by Pierre Desautels, P. Geo, AGP Mining Consultants Inc. and Paul Berndt, FAusIMM, dated April 9, 2018 and titled "NI 43-101 Resource Update for the RC and BN Zones and Maiden Resource Estimate for the BK Zone of the Fox Tungsten Project British Columbia" available on the Company's website at www.happycreekminerals.com and on the Company's SEDAR+ profile at www.sedarplus.ca

Quality Assurance / Quality Control Procedures

NQ size diamond drill core was split and sampled over intervals ranging from 0.38 metres to 2.35 metres and averaging approximately 1.3 metres. Samples were shipped to, prepared, and analyzed at ALS Canada Ltd (ALS) in North Vancouver, British Columbia. ALS meets all requirements of International Standards ISO/IEC 17025:2005 and ISO 9001:2015 for analytical procedures. Samples are analyzed for tungsten using ALS's fusion method W-XRF10, and for trace elements by ultra-trace aqua regia method ME-ICP41. Results for tungsten are presented by ALS in % W. For its own reporting, the Company converts W to WO3 (tungsten trioxide) by multiplying the reported W value 1.261 to obtain WO3, which is the compound for which tungsten concentrate and prices are quoted. In addition to ALS internal laboratory quality assurance / quality control, Happy Creek implements an internal QA/QC program that includes the insertion of sample blanks, duplicates, and certified reference standards in the string of drill core samples.

On behalf of the Board of Directors,

"Stephen Gray"

President and Chief Executive Officer
