Beauce Gold Fields Achieves 88% Drill Success Rate at the Grondin Zone. 3-D Interpretation Confirms 600 M Mineralized Corridor

(TheNewswire)

December 17, 2025 – TheNewswire - Montreal, Quebec, Canada -  Beauce Gold Fields (Champs d’Or enBeauce) (TSX Venture: BGF), referred to as“BGF” or the “Company,” is pleased to announce a majoradvancement in understanding the gold-bearing Grondin Zone with thecompletion of a Leapfrog™ 3-D geologicalmodel integrating drill data from the2023 and 2025 diamond drill campaigns. The new model provides thefirst three-dimensional visualization of the antiform–saddle reef mineralized system that the Company has previously traced along an 8-kmgeophysical signature and drilled over a strike length of 600metres.

Patrick Levasseur, President and CEO of Beauce Gold Fields, stated:“ThisLeapfrog 3-D model is a major milestone for Beauce Gold Fields. Forthe first time, we can visualize the geometry of the gold-bearingsaddle-reef structure in three dimensions and clearly see thecontinuity of mineralization along more than 600 metres. Achieving an88% drill success rate across two campaigns gives us tremendousconfidence. This model will greatly improve our drill targeting thiswinter and positions us for an exciting next phase ofexploration.”

3-D Geological ModelHighlights

The 3-D model incorporatesdigitized drill sections, gold assay intervals, lithological logs, andstructural interpretations derived drill holes from the Grondin Zone,including 2023 holes GR-23-01 toGR-23-08 and2025 holes GR-25-01 toGR-25-08, weredigitized, georeferenced, and importedinto Leapfrog™ togenerate a high-resolution geological model of the antiform-hostedmineralized system.  The model displays the discovery of gold-bearinghydrothermal breccias, quartz crack-and-seal vein pockets within afolded felsic lapilli tuff sequence.

• Gold-bearing intervals from 0.200 ppm to 11 ppm grouped into vertical planar sections by grade 

• A folded, arcuate saddle-reef antiformgeometry consistent with structurallyrepeated zones of gold enrichment 

• A 600-metres mineralized strikelength extending from GR-23-08toGR-25-08 

• Mineralization traced to depths of ~40metres, remaining open both along strikeand at depth 

High Drill Success Rate ValidatesGeological Model

The Leapfrog model confirms that the Company’s recent2023 & 2025 combined Grondin drillprograms were highly effective intargeting this structure:

• 14of 16 holes returned gold ? 0.3 g/t Au 

• 88% drill-hole hit ratio—significantly above the industry norm for grassrootsexploration 

• Confirms BGF is drilling within a robust,continuous mineralized corridor 

BGF’s 88% success rate exceeds the performance of most discovery-stage juniorexplorers in Canada and underscores the strength of the Company’sstructural model.  In comparison, early-stage gold explorationtypically yields only 20–40%mineralized drill holes, with programs exceeding 50% generally considered highlysuccessful.

The procedures used for the recently reported drillresults, which were previously published in press releases datedNovember 1, 2023, and September 11, 2025, followed strict QA/QC protocols. Alldrilling recovered HQ  and NQ cores. Drill cores were split in halfusing a diamond saw. Half of the core was sampled and sealed in cleanplastic bags before being shipped for assay. Standards and blanks were inserted on site.  The remaining half of the core was replaced in core boxes andis stored at the Company's core shack in Saint-Simon-les-Mines,Quebec. Samples were sent to MSALABS,Val-d'Or, Quebec.  The entire samples were dried and crushed up to 1 kg to 70% -2mm and split into 500g samples. Each sample underwent Gamma ray analysis for gold by photon assayinstrument.

The 3-D interpretation provides:

• Improved visualization of mineralized continuity across multiple drill fences 

• Confirmation of saddle-reef geometry, astyle of folding known globally to host high-grade gold zones 

• Refined drill targeting for theupcoming winter drill campaign 

• Identification of gaps, hinge positions, and foldrepetition patterns requiring furthertesting 

• Integration with the 8-kmgeophysical signature confirmed in theOctober 17, 2024 press release 

• Step-out drilling to test lateral continuation alongthe 600-m corridor 

• Deeper drilling than the vertical extent of confirmedmineralization 

• Structural analysis to identify hinge-zone targetstypically associated with high-grade saddle-reef deposits 

• Integration with new geophysical, geochemical, andhistorical data sets 

One key missing element is the precisedip and orientation of the gold-bearingstructures. To resolve this, BGF plans to deploy a boreholeteleviewer to determine structural dip,planar features, and orientation parameters necessary to optimizedeeper drilling.

The Company believes that the new 3-D interpretation significantlyenhances its ability to define, target, and expand the gold-bearingstructures of the Grondin Zone

About Beauce Gold Fields

Beauce Gold Fields is focused on exploring anddeveloping the largest placer gold district in eastern North America.The Company’s objective is the trace old placer gold workings backto a bedrock source to uncover economic lode gold deposits.  TheCompany’s flagship property is the Saint-Simon-les-Mines goldproject, site of Canada’s first gold rush that pre-dates the YukonKlondike.  The Beauce region hosted some of the largest historicalplacer gold mines in Eastern North America that were active from 1860sto the 1960s It produced some of the largest gold nuggets in Canadianmining history (50oz+).

Beauce Gold Fields is currentlydrilling recently discovered antiform systems that is believed to havecontributed to the development of extensiveauriferous placer deposits in Beauce.  The Company’s geologicalmodel suggests that placer gold within theBeauce Gold paleochannel, including the renowned large nuggets fromthe 19th century, formed in stressed quartz pockets within layereddomed Axis of Antiforms, exemplified by Saddle Reef formations.Notable global Saddle Reef formations include the Bendigo goldfields in Australia (over 60 million ounces) and the high-gradeDufferin deposit in Nova Scotia.
