LaFleur Minerals Advancing Restart of Beacon Gold Mill and Bulk Sample for Swanson Gold Project

LaFleur Minerals Inc. (CSE: LFLR) (OTCQB: LFLRF) (FSE: 3WK0) ("LaFleur Minerals" or the "Company") is advancing towards a restart of the Company's 100%-owned Beacon Gold Mill in Val-d'Or, Québec and a Preliminary Economic Assessment (PEA) as it aims to restart production at the mill by early 2026. LaFleur Minerals plans to immediately launch a minimum 5,000-metre diamond drilling program at its highly prospective, district-scale Swanson Gold Project ("Swanson"). LaFleur Minerals also reiterates key results of its recent exploration programs, including an update on its diamond drilling and bulk sampling plans at Swanson, refer to LaFleur Minerals News Release dated June 4, 2025 and the LaFleur Minerals Webinar Replay dated June 5, 2025.

RESTART PLAN FOR BEACON GOLD MILL

• LaFleur Minerals is methodical and laser-focused on completing the necessary activities required to restart production at its fully permitted Beacon Gold Mill, a 750 tonne per day facility that underwent over C$20 million in repairs and refurbishments just prior to acquiring the asset in Fall 2024. The Company is also finalizing a PEA to evaluate the economics of an open-pit mining scenario at Swanson and the processing of the mineralized material at its Beacon Gold Mill, capitalizing on the current gold market rally with prices hovering above USD$3,300 per ounce.

• The Beacon Gold Mill greatly benefits from numerous gold deposits in its vicinity for bulk sampling and custom milling opportunities, existing infrastructure, and direct access to roads, power, and skilled labor, which further enhances the overall value proposition of LaFleur Minerals by providing an anticipated path to production and revenue-generation. As part of its ongoing mill assessment, the Company has developed a comprehensive mill restart plan which includes improvements of ~C$3.8 million for mill equipment and maintenance, and tailings storage facility repairs of ~C$1.8 million. The Company is evaluating the processing of a large bulk sample from the Swanson gold deposit at the Beacon Mill to test its metallurgical and processing characteristics. The Beacon Mill's viability is further supported by the fact that it has no outstanding royalties or encumbrances given that previously issued royalties were eliminated during the Monarch Mining Companies' Creditors Arrangement Act (CCAA) process, and the Company also holds a $2.4 million bond on the mill as a backstop.

SWANSON GOLD DEPOSIT

• The Swanson Gold Project is a district scale 166 km² project that includes numerous prospects rich in gold and critical metals previously held by Monarch Mining, Abcourt Mines, and Globex Mining. The Swanson Gold Project hosts an Indicated Mineral Resource of 2,113,000 t with an average grade of 1.8 g/t gold for 123,400 oz of contained gold and 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, and LaFleur Minerals has targeted aggressive exploration and drilling this season to increase the gold resource at the Swanson Gold Project based on 4 primary target areas with new and historical gold occurrences (Swanson, Bartec, Marimac, and Jolin targets).

Bulk Sample Planning in Progress:

• Planning and permitting is currently underway for an up to 100,000-tonne bulk sample from the existing mining lease hosting the Swanson Gold Deposit, which would be tested for its metallurgical and processing characteristics at the Beacon Mill once it becomes fully operational. A bulk sample mining and environmental closure and remediation plan is currently being finalized for regulatory approval with the Québec government.

• Over 50 drill hole targets have been identified at Swanson and nearby Bartec, Jolin, and Marimac. Recent high-grade results-including 11.7 g/t Au in a grab sample at Jolin-point to significant upside as the Company prepares to test multiple new zones. The Company's immediate plans are to complete at least 5,000 metres of diamond drilling at Swanson starting in June using existing flow-through (FT) funds. Refer to the Company's news release dated June 4, 2025 for further details on recent exploration work by LaFleur Minerals at Swanson which included geological mapping and prospecting, soil sampling surveys, and Induced Polarization (IP) geophysics surveys.

Paul Ténière, CEO of LaFleur Minerals stated:

"We are grateful to have acquired the fully permitted and refurbished Beacon Gold Mill, which received over C$20 million in upgrades by its previous operator and is located in the midst of numerous gold deposits in the historic Val-d'Or and Rouyn-Noranda mining districts, including our own Swanson Gold Deposit. Based on our recent detailed assessments, the Beacon Gold Mill requires minimal repairs and improvements, and we are methodically executing a strategy to eventually restart production at the mill. We are also excited to commence planning for a large bulk sample at Swanson and a PEA to evaluate a mining and processing scenario at current record gold prices. With gold prices at record highs this is a pivotal year for LaFleur Minerals as we focus on restarting gold production at the Beacon Gold Mill and diamond drilling at the Swanson Gold Project to increase mineral resources."
