Beauce Gold Fields Announces Substantial Increase in Exploration Target for Saint-Simon-les-Mines Paleoplacer Channel

MONTREAL, Quebec, Canada — June 9, 2026 — Leads & Copy — Beauce Gold Fields (Champs D’Or en Beauce), referred to as “BGF” or the “Company,” has announced the results of an updated technical assessment of the Saint-Simon-les-Mines Paleoplacer Channel in the Beauce region of southern Québec. The revised exploration target estimates a range between 4,004,674 to 5,991,229 cubic metres grading 2.02 g Au/m³ to 12.0 g Au/m³. This represents a substantial increase from the Company's previously announced September 2025 Exploration Target of 3.86 million cubic metres grading between 0.81 g Au/m³ and 4.9 g Au/m³.

The new interpretation, prepared by independent Qualified Person Jean Bernard, P.Geo., significantly enhances the understanding of the Saint-Simon-les-Mines paleoplacer system. This updated assessment supports the view that the Gilbert River paleovalley remains a compelling placer gold exploration opportunity in eastern North America. The revised findings also strengthen the connection between the paleoplacer deposits and the Company's Saddle Reef-style bedrock gold discoveries located immediately north of the channel.

The Exploration Target is based on the interpretation of historical drilling, geological modeling of the Gilbert River paleovalley, polygonal volumetric calculations, and the evaluation of auriferous saprolite and basal sedimentary units. The potential quantity and grade are conceptual in nature, and insufficient exploration has been completed to define a mineral resource, with no certainty that further exploration will result in such a delineation.

The updated target reflects several key geological factors: an expansion of the interpreted paleochannel and associated deltaic deposits; the inclusion of additional saprolite-hosted gold-bearing material; the recognition of natural gold traps within the Beauceville Formation; an improved understanding of the Gilbert River paleovalley’s geometry through reconstruction of historical sections and longitudinal profiles; and the integration of historical drilling databases and geological information spanning over six decades.

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

Beauce Gold Fields is focused on exploring and developing the largest placer gold district in eastern North America, aiming to trace old placer gold workings back to a bedrock source. The Company’s flagship property, the Saint-Simon-les-Mines gold project, is the site of Canada’s first gold rush. The Beauce region hosted significant historical placer gold mines from the 1860s to the 1960s, producing some of the largest gold nuggets in Canadian mining history.

The Company is currently drilling recently discovered antiform systems believed to have contributed to the extensive auriferous placer deposits in Beauce. Their geological model suggests that placer gold within the Beauce Gold paleochannel, including notable 19th-century nuggets, formed in stressed quartz pockets within layered domed axes of antiforms, exemplified by Saddle Reef formations. Similar global Saddle Reef formations include the Bendigo gold fields in Australia and the Dufferin deposit in Nova Scotia.
