Canada's First Gold Rush Re-Evaluated for Both Paleoplacer Gold and Bedrock Saddle-Reef Gold.
A historically mined paleoplacer channel with modern evaluation potential, and an emerging Saddle Reef bedrock-source discovery directly linked to the placer system.

The Beauce gold sector straddles two of the major tectonostratigraphic subdivisions of the Appalachians. The latter is the Gander zone to the northwest and that of Dunnage to the southeast.
Several large gold systems have been identified along this structural zone, including New Found Gold's Queensway gold project and Calibre's Valentine Lake Deposit in Newfoundland.
The Saint-Simon-les-Mines paleoplacer channel forms the heart of the historic Beauce Gold district, the site of Canada's first gold rush, which predates the Klondike by nearly 50 years.
From the 1850s through the early 1900s, placer gold was mined extensively from underground workings and later by large-scale dredging operations during the 1960s. Historical records indicate that the Beauce hosted one of the largest placer gold districts in Eastern North America, producing coarse gold and numerous large nuggets.
Modern reinterpretation of the district by Beauce Gold Fields suggests the historical mining focused primarily on portions of a much larger auriferous paleoplacer system preserved beneath glacial overburden.
The Company's exploration has identified:
Recent 3D modelling, historical drill-log recovery, seismic interpretation and horizontal directional drilling (HDD) support the concept that the Saint-Simon paleoplacer system remains open laterally and at depth.

Recent 3D modelling, historical drill-log recovery, seismic interpretation and horizontal directional drilling (HDD) support the concept that the Saint-Simon paleoplacer system remains open laterally and at depth.
Based on historical drilling, geological modeling and recent reinterpretation work, the Company has outlined a conceptual Exploration Target for the Saint-Simon-les-Mines paleoplacer channel. The target is associated with auriferous saprolite and basal till horizons buried beneath overburden of the Gilbert River paleovalley. Historical placer production, including coarse gold and multi-ounce nuggets, suggests the system may be characterized by a strong nugget effect.
Historical placer production records from the Beauce district indicate the gold consistently contained significant silver content, matching modern analyses from the Grondin antiform system.
This chemical fingerprint provides additional evidence linking the historical placer deposits to the newly identified Saddle Reef antiform structures.
The Exploration Target is conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further exploration will result in the estimation of a Mineral Resource. See the Company's press releases dated May 2, 2025 and May 29, 2025 for full details.
Beauce Gold Fields is the first company to systematically explore the bedrock source of the historic Beauce placer gold deposits.
The Company's geological model proposes that coarse placer gold and nuggets originated from Saddle Reef-style mineralization associated with antiform fold structures and hydrothermal quartz stockworks.
Exploration programs including:
Diamond drilling and trenching at the Grondin Zone confirmed gold mineralization within:
The geological setting shares similarities with Saddle Reef systems such as Bendigo, Australia.

Modern geochemical analysis conducted on gold grains recovered from the Grondin antiform outcrop confirmed that the Beauce gold system also contains a significant silver component.
Scanning Electron Microscope (SEM-EDS) analyses of gold grains recovered from bulk sampling at the Grondin Zone returned average compositions of approximately:
Importantly, this silver content closely matches:
The strong correlation between silver content in:
Silver enrichment is commonly associated with orogenic gold systems and provides additional evidence supporting the Company's Saddle Reef geological model.
The Beauce district produced Canada's first documented gold rush in the 1800s. Today, Beauce Gold Fields is re-evaluating those same channels with modern geophysics, sonic drilling and 3D modelling — bridging more than 175 years of gold geology.
The Beauce district possesses a unique gold-mining heritage deeply connected to the identity and history of the region.
Beauce Gold Fields has worked closely with local stakeholders, municipalities and landowners to advance exploration responsibly while preserving the historical significance of the district.
The Company prioritizes:
The historical mining heritage of Saint-Simon-les-Mines remains visible today through preserved mining infrastructure, historical records and the Promenade des Mines heritage park.
On-the-ground exploration, sampling, drilling and field operations.
Heritage of Canada's first gold rush district.
