Beauce Gold Fields Announces Positive Analytical and Metallurgical Results from CH-98 Phosphate Property

Montréal, Québec — March 12, 2026 — Leads & Copy — Champs d’Or en Beauce (Beauce Gold Fields) (TSX Croissance: BGF) has released analytical results from apatite-bearing rock samples collected from its CH-98 phosphate property in the Lac-Saint-Jean region of Quebec. The company also announced results from metallurgical tests conducted by COREM on apatite material from the property.

The work follows a press release from November 17, 2025, that announced the presence of apatite-rich anorthosite and confirmed the historical phosphate index CH-98-61.

Patrick Levasseur, President and CEO of Beauce Gold Fields, stated that the analyses confirm significant phosphate content at index CH-98-61. Levasseur added that metallurgical tests by COREM show that apatite from the property can be enriched into a high-grade phosphate concentrate using conventional flotation methods, confirming the potential of the CH-98 property as part of the Québec Phosphate initiative. The goal is to position Beauce Gold Fields to contribute to North American phosphate supply.

During the 2025 field campaign on the CH-98 property, apatite-bearing rock samples were taken at five locations, including directly on the outcrop of index CH-98-61. The samples were sent to ALS Canada Ltée in Val-d’Or, Quebec, for geochemical whole rock analyses by X-ray fluorescence (XRF). Sample CH-98-61 yielded a grade of 8.07% P₂O₅, confirming high phosphate values reported in historical government sampling that recorded 8.59% P₂O₅ on the same outcrop. The sampled rocks are composed mainly of anorthosite containing apatite, a host lithology recognized for phosphate deposits in the Lac-Saint-Jean anorthositic complex.

A 20 kg sample of apatite-bearing rock from the CH-98-61 outcrop was submitted to COREM (Quebec) to evaluate the possibility of producing an apatite concentrate by flotation. Flotation tests indicate that the material responds favorably to conventional mineral processing methods, producing apatite concentrates exceeding 35% P₂O₅. The best flotation test yielded 38.9% P₂O₅ with a recovery of 93.4% and low impurities (minor element ratio of 0.05). Analysis of the concentrate also indicates 0.19% total rare earth oxides (TREO) and low levels of thorium (<5 ppm) and uranium (1.3 ppm).

The metallurgical tests were performed on a feed sample containing approximately 5.6% P₂O₅. Concentrate grades obtained during flotation tests are comparable to those reported by advanced phosphate projects in the Lac-Saint-Jean anorthositic district, where concentrates obtained after flotation typically range between 35% and 40% P₂O₅. Tests on material from the CH-98 property produced concentrates reaching 38.9% P₂O₅ with 93.4% recovery, demonstrating that the property's apatite mineralization can be enriched using conventional processes similar to those used by other phosphate projects in the region.

The company plans to continue exploration on the CH-98 property through detailed mapping and prospecting, groove sampling of apatite-bearing outcrops, geophysical surveys to identify favorable lithologies and structures, and evaluation of additional samples for metallurgical testing. These efforts aim to better define the extent and continuity of phosphate mineralization on the property.

Samples from the 2025 field program were analyzed by ALS Canada Ltée in Val-d’Or, Quebec, an ISO-certified laboratory. The company’s qualified person has reviewed the analytical procedures and deems them appropriate for this type of mineralization.

Metallurgical tests were conducted by COREM, an independent mineral processing research center in Quebec City. Approximately 13.8 kg of representative material was prepared by crushing and homogenization before flotation tests. The results presented come from laboratory tests performed under controlled conditions and do not constitute an optimization study or an economic feasibility study.

The CH-98 property is part of Beauce Gold Fields’ Québec Phosphate initiative, which targets phosphate occurrences within the Lac-Saint-Jean anorthositic complex, a major phosphate-titanium district in North America. Phosphate is essential for fertilizer production and is also a key component of LFP (lithium-iron-phosphate) battery cathodes. The company’s strategy is to advance near-surface targets that can contribute to the North American supply chain of critical minerals. Phosphate has recently been added to the critical minerals lists of Canada and Quebec.

Beauce Gold Fields is focused on the exploration and development of the largest placer gold district in eastern North America. The company's objective is to trace the historical placer gold workings back to their bedrock source to discover economically viable gold deposits. The company’s flagship property is the Saint-Simon-les-Mines gold project, site of Canada's first gold rush. Beauce region hosted some of the largest historical placer gold operations in eastern North America between the 1860s and 1960s, producing some of the largest gold nuggets in Canadian mining history (over 50 ounces).

Beauce Gold Fields continues to drill newly discovered antiform systems that are believed to have contributed to the formation of the Beauce’s placer gold deposits. The company’s geological model suggests that the Beauce paleochannel placer gold, including the large 19th century nuggets, formed in stress-related quartz pockets located in the axis of stratified antiform domes, typical of Saddle Reef type formations. Notable Saddle Reef formations worldwide include the Bendigo goldfields in Australia and the high-grade Dufferin deposit in Nova Scotia.
