LaFleur Minerals Updates PEA and Beacon Gold Mill Restart Work

LaFleur Minerals Inc. (CSE: LFLR) (OTCQB: LFLRF) (FSE: 3WK0) (‘LaFleur Minerals‘ or the ‘Company‘ or ‘Issuer‘) is pleased to announce major advancements with its Swanson Gold Deposit and Beacon Gold Mill which includes the advancement of technical studies evaluating the restart of gold production and retrofits to increase production rates at Beacon, as well as establishing requirements to expand its existing permitted tailings facility, all key components supporting the upcoming Preliminary Economic Assessment (PEA), which are in the final stage. The significant progress of key technical, metallurgical and infrastructure milestones for the PEA is integral to a disciplined, capital-efficient mill restart, which includes recently finalized positive verification of historical drilling with results to be announced near-term and ongoing recommissioning work at the Company’s wholly-owned Beacon Gold Mill.

PATH TO GOLD PRODUCTION RESTART AT BEACON GOLD MILL:

The Beacon Gold Mill last operated in 2022 with gold prices in the $1,800-2,000/oz range. With gold prices currently exceeding $4,900/oz, Lafleur is laser focused on restarting gold production at the Beacon Gold Mill leveraging supply from its 100%-owned district-scale Swanson Gold Deposit, located only ~50 km away, forming its vertically-integrated production model. The Swanson Gold Project, one of the largest gold exploration land packages in the Abitibi Gold Belt, Val-d’Or, Québec, holds a 43-101 compliant open pit and underground mineral resource; Total Indicated Mineral Resource Estimate of 2,113,000 t with an average grade of 1.8 g/t gold for 123,400 oz of contained gold, and Total Inferred Mineral Resource Estimate of 872,000 t with an average grade of 2.3 g/t gold for 64,500 oz of contained gold (MRE effective September 17, 2024 and reported in updated NI 43-101 technical report dated July 29, 2025). With a fully permitted tailings storage facility and proximity to established mining infrastructure, the Beacon Gold Mill offers a strategic ready to restart gold mill at a time when gold prices remain strong (USD $4,833/oz as of January 22, 2026; KITCO).

In parallel with regional exploration and drilling activities, the Company is also advancing technical studies aimed at optimizing and expanding the mill’s capabilities. Current work includes detailed assessments to enhance the existing metallurgical facility, supported by the development of updated cost estimates and retrofit flow sheets. These studies form part of a broader growth strategy that contemplates substantially increasing mill throughput, modernizing the process flowsheet, and advancing drilling programs to continually expand the mineral resources available to feed the Beacon Gold Mill.

RECENT FINANCING OF $7,800,000 CLOSED – BEACON GOLD MILL FUNDED FOR RESTART

LaFleur’s positioning is distinct compared to peers as it’s not in the conceptual stage but in full execution, given its 100%-owned, fully permitted Beacon Gold Mill with current 750 tpd capacity, funded for restart and entering revenue-generation stage. Beacon Gold Mill is scalable to 1,000 tpd under the PEA base case and 3,000-4,000 tpd under long term growth scenarios, offering a rare vertically integrated, mine-to-mill gold production platform that is scalable, enhancing control over costs and margins, with the possibility to leverage rail-enabled logistics, strengthening and solidifying the mill as a potential regional processing hub in Val-d’Or. Lafleur recently completed a total of $7,800,421 in funding to fully fund the restart of gold production at the Beacon Gold Mill (refer to press release dated January 5, 2026).

TECHNICAL ADVANCEMENTS TOWARDS DELIVERY OF PEA

• The Swanson Deposit Mining Lease (BM885) has been reviewed for spatial suitability and is considered suited for the current mine plan. As the size of the mineral deposit and mining plan increases, the Company is evaluating opportunities to expand the permitted surface area through additional mining lease applications.
• Verification diamond drilling to support the PEA at the Swanson Gold Deposit is now complete. These positive drilling results will support the upcoming technical report and mark a key milestone in advancing the Project. The material from this drilling will also be used and incorporated in ongoing and future metallurgical testing. Lafleur will provide detailed news release on the positive drill results once final assat results are received in the coming days.
• LaFleur Minerals management team, together with ERM (Environmental Resources Management) and Canadian National Railway (CN), have initiated discussions regarding potential rail infrastructure enhancements to support long-term project development and delivery of feed from the Company’s Swanson Gold Project to Beacon Gold Mill. These discussions include a timeline for design and planning of relocating a small portion of the existing CN rail line (estimated at 6 months), then installing a dedicated rail spur to facilitate efficient loading and transport of material to the Beacon Gold Mill. The current CN line runs directly through both the Swanson Property and the Beacon Gold Mill site, presenting an opportunity to optimize logistics, reduce future hauling costs, decrease GHG emissions and support increased safety with less truck traffic through villages. Having direct rail access at the Beacon Gold Mill will significantly reduce transport costs and increase the range for the Company to accept satellite feed material, further enhancing the economics of gold production operations.
• Metallurgical planning for the Swanson Gold Project and Beacon Gold Mill continues to advance. Work being completed by Bumigeme Inc. (Bumigeme) of Montréal and ERM, the PEA lead consultant, regarding potential retrofits to the Beacon Gold Mill to support increased feed processing capacity. The C$49 million as-built and permitted Beacon Gold Mill facility remains a key strategic asset for LaFleur Minerals.

Work to date has focused on evaluating the requirements to economically process Swanson mineralized material at the Beacon Gold Mill and to further the mill expansion, including:

SWANSON GOLD PROJECT AND BEACON GOLD MILL – PEA BASE CASE ACTIVITIES

• Assessing upgrades to increase mill throughput to 1,000 tpd, including the capital costs associated with crushing, grinding and flotation circuit modifications.
• Initiating a metallurgical testing program for Swanson mineralized material, with a total of 400 kg of representative diamond-drill-core and assay rejects to be collected in January 2026 for detailed testwork by SGS Canada in February and March 2026.

GROWTH PLANNING

Looking beyond the PEA, LaFleur Minerals is assessing future Beacon Gold Mill expansion scenarios in the 3,000-4,000 tpd range:

• Preliminary capital requirements for these growth cases are currently under evaluation.
• Bumigeme and ERM are jointly developing the metallurgical flowsheet options to support these potential expansions, which will be supported by metallurgical laboratory testing.
• The current Beacon Gold Mill infrastructure is supported by an existing 4 MW power supply, providing a strong electrical foundation for current operations and planned throughput increases. This existing capacity enables the Company to evaluate upgrades in the PEA base case and supports future expansion scenarios.
• Mine options analysis and associated economic trade-off studies are currently being undertaken to evaluate the viability of processing Swanson mineralized material at the Beacon Mill. These evaluations are intended to quantify the relative merits of alternative development pathways and to inform the selection of the preferred mine-to-mill configuration.
• As metallurgical modernization concepts for the Beacon Gold Mill advance toward fully defined and executable process designs, the scope of the economic assessments may be expanded to incorporate additional growth scenarios, a sustainable environmentally friendly flowsheet and longer-term production strategies.
