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

(via TheNewswire)   December 17, 2025 – TheNewswire - Montreal, Quebec, Canada -  Beauce Gold Fields (Champs d’Or en Beauce) (TSX Venture: BGF) , referred to as “BGF” or the “Company,” is pleased to announce a major advancement in understanding the gold-bearing Grondin Zone with the completion of a Leapfrog™ 3-D geological model integrating drill data from the 2023 and 2025 diamond drill campaigns. The new model provides the first three-dimensional visualization of the antiform–saddle reef mineralized system that the Company has previously traced along an 8-km geophysical signature and drilled over a strike length of 600 metres. Patrick Levasseur, President and CEO of Beauce Gold Fields, stated: “This Leapfrog 3-D model is a major milestone for Beauce Gold Fields. For the first time, we can visualize the geometry of the gold-bearing saddle-reef structure in three dimensions and clearly see the continuity of mineralization along more than 600 metres. Achieving an 88% drill success rate across two campaigns gives us tremendous confidence. This model will greatly improve our drill targeting this winter and positions us for an exciting next phase of exploration.”   Click Image To View Full Size Image: 3-D geological model of the Grondin Zone’s antiform–saddle reef mineralized system 3-D Geological Model Highlights The 3-D model incorporates digitized drill sections, gold assay intervals, lithological logs, and structural interpretations derived drill holes from the Grondin Zone, including 2023 holes GR-23-01 to GR-23-08 and 2025 holes GR-25-01 to GR-25-08 , were digitized, georeferenced, and imported into Leapfrog™ to generate a high-resolution geological model of the antiform-hosted mineralized system.  The model displays the discovery of gold-bearing hydrothermal breccias, quartz crack-and-seal vein pockets within a folded 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 antiform geometry consistent with structurally repeated zones of gold enrichment   A 600-metres mineralized strike length extending from GR-23-08 to GR-25-08   Mineralization traced to depths of ~40 metres , remaining open both along strike and at depth   High Drill Success Rate Validates Geological Model The Leapfrog model confirms that the Company’s recent 2023 & 2025 combined Grondin drill programs were highly effective in targeting this structure: 14 of 16 holes returned gold = 0.3 g/t Au   88% drill-hole hit ratio — significantly above the industry norm for grassroots exploration   Confirms BGF is drilling within a robust, continuous mineralized corridor   BGF’s 88% success rate exceeds the performance of most discovery-stage junior explorers in Canada and underscores the strength of the Company’s structural model.  In comparison, early-stage gold exploration typically yields only 20–40% mineralized drill holes, with programs exceeding 50% generally considered highly successful.

All drilling recovered HQ  and NQ cores. Drill cores were split in half using a diamond saw. Half of the core was sampled and sealed in clean plastic bags before being shipped for assay. Standards and blanks were inserted on site.   The remaining half of the core was replaced in core boxes and is 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 assay instrument. The 3-D interpretation provides: Improved visualization of mineralized continuity across multiple drill fences   Confirmation of saddle-reef geometry , a style of folding known globally to host high-grade gold zones   Refined drill targeting for the upcoming winter drill campaign   Identification of gaps, hinge positions, and fold repetition patterns requiring further testing   Integration with the 8-km geophysical signature confirmed in the October 17, 2024 press release   Step-out drilling to test lateral continuation along the 600-m corridor   Deeper drilling than the vertical extent of confirmed mineralization   Structural analysis to identify hinge-zone targets typically associated with high-grade saddle-reef deposits   Integration with new geophysical, geochemical, and historical data sets   One key missing element is the precise dip and orientation of the gold-bearing structures. To resolve this, BGF plans to deploy a borehole televiewer to determine structural dip, planar features, and orientation parameters necessary to optimize deeper drilling. The Company believes that the new 3-D interpretation significantly enhances its ability to define, target, and expand the gold-bearing structures of the Grondin Zone Jean Bernard, BSc, Geo, a qualified independent person as defined by National Instrument 43-101, has reviewed and approved the technical content of this release. About Beauce Gold Fields   Beauce Gold Fields is focused on exploring and developing the largest placer gold district in eastern North America. The Company’s objective is the trace old placer gold workings back to a bedrock source to uncover economic lode gold deposits.  The Company’s flagship property is the Saint-Simon-les-Mines gold project, site of Canada’s first gold rush that pre-dates the Yukon Klondike.  The Beauce region hosted some of the largest historical placer gold mines in Eastern North America that were active from 1860s to the 1960s It produced some of the largest gold nuggets in Canadian mining history (50oz+). (Source Sedar: 43-101 Report - Beauce July 4 th 2018, Author B. Violette)   Beauce Gold Fields is currently drilling recently discovered antiform systems that is believed to have contributed to the development of extensive auriferous placer deposits in Beauce.  The Company’s geological model suggests that placer gold within the Beauce Gold paleochannel, including the renowned large nuggets from the 19th century, formed in stressed quartz pockets within layered domed Axis of Antiforms, exemplified by Saddle Reef formations. Notable global Saddle Reef formations include the  Bendigo gold fields in Australia (over 60 million ounces) and the high-grade Dufferin deposit in Nova Scotia.   Beauce Gold Fields website www.beaucegold.com   Disclaimers: This press release contains certain forward-looking statements, including, without limitation, statements containing the words "may", "plan", "will", "estimate", "continue", "anticipate", "intend", "expect", "in the process" and other similar expressions which constitute "forward-looking information" within the meaning of applicable securities laws.
