Beauce Gold Fields Significantly Expands Exploration Target of the Saint-Simon-Les-Mines Paleoplacer Channel

Montreal, Quebec — Beauce Gold Fields (Champs D’Or en Beauce) (TSX Venture: “BGF”), referred to as “BGF” or the “Company,” referred to as “BGF” or the “Company,” is pleased to announce the results of a comprehensive technical assessment of its flagship Saint-Simon-les-Mines placer gold property located in the Beauce region of southern Quebec. The report incorporates newly recovered historical drill data, high-resolution lidar mapping, and reinterpretation of stratigraphic and structural models to significantly expand the Company’s gold exploration target.

Gold Exploration Target Doubled from Previous Estimate

The updated 2025 polygonal-based model defines an Exploration Target ranging between:

• 3.86 million m³ @ 0.81 g Au/m³ to
• 3.86 million m³ @ 4.9 g Au/m³, including nugget effect.

This represents a near doubling of the previous 2015 target, which estimated a range of 2,200,000 m3 @ 0.87g Au/m3 and 2,200,000 m3 @ 5.22 g Au/m3 (Source Sedar: 43-101 Report – Beauce, July 4th 2018, Author B. Violette). The new estimates are grounded in historical drilling by Beauce Placer Co. (1958–1960), Coniagas Resources (1985), Ressources Macamic (1987–88), and BGF (2021), now georeferenced and integrated with lidar-derived paleo-valley reconstructions. BGF rediscovered over 344 original drill logs and cross sections from Beauce Placer Co. 1958-1959 churn drilling (BGF press release January 11, 2021), which had not been used in any prior modern assessment. These documents were instrumental in reconstructing five detailed 1:1,000 scale relief maps of the paleo valley and refining exploration polygons. The updated report titled (in French), Rapport technique sur les cibles d’exploration aurifère du canal paleoplacer de Saint-Simon-les-Mines, Aout 2025, by Jean Bernard, géo, an independent Qualified Person (QP) under National Instrument 43-101, will be deposited on Sedar.

The Exploration Target mentioned is conceptual in nature. There has been insufficient exploration to define a mineral resource, and there can be no assurance that further exploration will result in the definition of such a resource.

Key Geological Highlights

• Two auriferous host units confirmed: a saprolitic altered bedrock horizon and an underlying brown glacial diamicton, both enriched in visible coarse gold.
• New mapping delineates three tributary-fed deltaic targets along the Gilbert River paleochannel, suggesting significant upstream gold input.
• Structural interpretation reveals multiple antiform “Saddle Reef”-style folds associated with quartz veining and gold-bearing stockwork believed to be the source of the placers.

Patrick Levasseur, President and CEO of Beauce Gold Fields, stated: “This is the most comprehensive geological review of the Saint-Simon-les-Mines placer channel since the 1960s. By integrating historic and modern data, we have improved the definition, volume, and grade confidence of the placer system, which now clearly exceeds half a million ounces potential with strong indications of proximity to bedrock lode sources.” Mr. Levasseur further stated, “This report validates that the Gilbert River paleoplacer system has been historically underestimated. With this new target, we are not only reviving a legacy gold district but elevating its potential to a modern exploration success story.”

The Company intends to apply for an ATI Authorization from Quebec’s Ministry of Natural Resources (MRNF) for “impact exploration work” which is valid for a period of two years for the proposed exploration activities:

• Expand its 2025 sonic drill program to test unverified deltaic extensions;
• Pursue bulk sampling across high-priority polygons identified in the report;
• Continue geometallurgical and nugget-effect characterization studies;

The technical information in this news release has been reviewed and approved by Jean Bernard, géo, an independent Qualified Person (QP) under National Instrument 43-101.
