Beauce Gold Fields Announces Updated Technical Evaluation of Saint-Simon-les-Mines Paleoplacer Channel

Montréal, Québec, Canada — June 9, 2026 — Leads & Copy — Beauce Gold Fields (TSX Venture: BGF) announced updated technical evaluation results for the Saint-Simon-les-Mines paleoplacer channel in Quebec. The June 2026 technical review significantly enhances the understanding of the Saint-Simon-les-Mines paleoplacer system, indicating increased potential in both volume and grade.

The company believes the Gilbert River paleovalley remains one of North America's most promising placer gold exploration opportunities. This new interpretation also strengthens the link between paleoplacer deposits and Saddle Reef gold discoveries in bedrock identified by the company immediately north of the channel.

The revised exploration target is estimated to contain between 4,004,674 and 5,991,229 cubic meters with grades ranging from 2.02 g Au/m³ to 12.0 g Au/m³. This target is based on historical drill data interpretation, geological modeling of the Gilbert River paleovalley, polygonal volume calculations, and an evaluation of gold-bearing saprolitic and sedimentary units by Jean Bernard, an independent qualified person.

It is important to note that the potential quantity and grade of this exploration target are conceptual. Current exploration work is insufficient to define a mineral resource, and there is no guarantee that further exploration will result in the delineation of a mineral resource.

The evaluation, prepared by Jean Bernard, incorporates additional geological interpretation, reconstruction of the Gilbert River paleovalley, analysis of historical drill data, and assessment of saprolitic and sedimentary units. These efforts have led to a substantial increase in the company's exploration target for the Saint-Simon-les-Mines paleoplacer system.

This updated target represents a significant increase compared to the target announced in September 2025, which was estimated at 3.86 million cubic meters with grades ranging from 0.81 g Au/m³ to 4.9 g Au/m³.

The updated target reflects several key findings:

• The expansion of the interpreted paleoplacer channel and associated deltaic deposits.
• The inclusion of additional volumes of gold-bearing material within the saprolite.
• The identification of natural gold traps developed within the Beauceville Formation.
• An improved understanding of the Gilbert River paleovalley's geometry through the reconstruction of historical cross-sections and longitudinal profiles.
• The integration of historical drill databases and geological information gathered over six decades.

The report concludes that gold mineralization is concentrated in basal gravel horizons, saprolitic bedrock, and structural traps within fractured basement rock along the paleovalley floor. Historical drilling and mining records consistently show the presence of coarse gold and nuggets throughout the system.

Jean Bernard, B.Sc., geo., a qualified person under NI 43-101, has reviewed and approved the technical content of this news release.

About Beauce Gold Fields Inc.

Beauce Gold Fields Inc. is a gold exploration company focused on the Beauce region of southern Quebec. The company's flagship property is the St-Simon-les-Mines gold project, the site of Canada's first gold rush, predating the Klondike Gold Rush. The Beauce region historically hosted some of Eastern North America's largest placer gold mines from the 1860s to the 1960s, producing some of the largest gold nuggets in Canadian mining history.

Beauce Gold Fields aims to trace ancient placer gold workings back to their bedrock source to discover an economic gold deposit. The company is currently exploring newly discovered antiform systems that may have contributed to the vast Beauce placer deposits. The geological model suggests that placer gold in the Beauce Gold paleochannel, including significant 19th-century nuggets, originated from quartz tension gashes within stratiform domed antiform axes, exemplified by Saddle Reef formations.
