Vancouver, British Columbia--(Newsfile Corp. - July 7, 2026) - LaFleur Minerals Inc. (CSE: LFLR) (OTCQB: LFLRF) (FSE: 3WK0) ("LaFleur Minerals" or the "Company") announces that it has agreed with Trafigura Canada Limited ("Trafigura") to an extension of the exclusivity and due diligence period under the previously announced indicative terms and conditions and accompanying indicative term sheet dated April 10, 2026 for a proposed prepayment facility of up to C$30 million (the "Prepayment Facility") and gold doré purchase agreement (the "Offtake Agreement", and together with the Prepayment Facility, the "Proposed Agreements"), as announced by the Company on April 15, 2026 and subject to definitive documentation, due diligence and closing conditions.

SUMMARY

On April 15, 2026, LaFleur Minerals announced it had selected Trafigura to arrange and provide a prepayment facility of up to C$30 million and gold doré purchase agreement for the proposed development of the Swanson Gold Deposit and processing operations at the Company's wholly-owned Beacon Gold Mill, located in Val-d'Or, Québec, subject to definitive documentation, due diligence and closing conditions.

The Proposed Agreement was subject to the execution of definitive documentation and the satisfaction of relevant conditions precedent, including the completion of Trafigura's due diligence and receipt of applicable internal approvals.

The proposed C$30 million Prepayment Facility would have no commodity price hedging requirements and will underpin required funding for LaFleur's processing facility operations and ramp-up towards a targeted processing capacity of 1,250 tonnes per day (tpd) at the Beacon Gold Mill and development work at the Swanson Gold Deposit (refer to April 15, 2026 News Release).

TRAFIGURA EXTENDED EXCLUSIVITY PERIOD

• The exclusivity and due diligence period has been extended to August 31, 2026 (the "Extended Exclusivity Period").

• The extension is intended to accommodate technical due diligence, the scheduling of the site visit, and agreement of definitive documentation in respect of the Proposed Agreements.

• Part of the ongoing due diligence will be a site visit to the Beacon Gold Mill and the Swanson Gold Deposit, and both parties are working to schedule the visit by August 15, 2026, subject to each party's staff availability to travel to Val-d'Or, Québec.

• The Proposed Agreements remain subject to the execution of definitive documentation and the satisfaction of relevant conditions precedent, including completion of Trafigura's due diligence and receipt of applicable internal and regulatory approvals.

Paul Ténière, CEO and Director of LaFleur Minerals, commented: "Technical due diligence on the Project is well advanced and the process with Trafigura has been very constructive throughout. A strategic next step is a site visit by the Trafigura team to our Beacon Gold Mill and Swanson Gold Deposit, and this exclusivity extension provides the time needed to finalize scheduling of that visit. We are very pleased with how the process with Trafigura has advanced. Collaborating with a global commodities leader of Trafigura's scale is a strong validation of the Swanson Gold Project and the Beacon Gold Mill, and the proposed non-dilutive structure is designed to support a disciplined restart while preserving shareholder value. We are also very pleased at our progress at refurbishing the Beacon Gold Mill and we are at 84% completion rate as of July 1,2026. We look forward to providing further updates as the Proposed Agreements progress."

Conditions and Exclusivity Status

During the Extended Exclusivity Period, and consistent with the terms of the indicative term sheet, the Company has agreed that neither it nor its representatives, officers, directors, agents or advisers will initiate, solicit, negotiate or accept any competing proposal from any third party in respect of the Proposed Agreements. Other than customary provisions, including those relating to exclusivity, the indicative term sheet is non-binding. The Proposed Agreements remain subject to Trafigura's due diligence and receipt of all necessary approvals, including legal and credit assessment and compliance with applicable regulatory requirements, and remain subject to Canadian Securities Exchange approval, if required. There can be no assurance that the parties will enter into definitive agreements or that the transaction contemplated by the Proposed Agreements will be completed on the terms contemplated, or at all.

Beacon Gold Mill Recommissioning Update - 84% Complete

LaFleur Minerals is also pleased to provide an update on the reconditioning and recommissioning of its 100%-owned Beacon Gold Mill ("Beacon Mill") located near Val-d'Or, Québec. As of July 1, 2026, the Beacon Mill mechanical reconditioning program is approximately 84% complete and remains on budget. The crushing, grinding, filtration, ore-storage, thickening and reagent circuits are each substantially complete, with the filtration circuit essentially finished and the thickener refurbishment complete. Completed work includes overhaul of the primary jaw crusher and the secondary and tertiary cone crushers, relining of the ball mill, refurbishment of the drum filters and vacuum systems, and reconditioning of pumps, conveyors and chutes throughout the plant.

Significant progress was made in the leaching circuit during the month of June. The new agitator mechanisms and air-lift assemblies for the leach tanks have now largely been received and fitted, with sandblasting, painting and final mechanism installation representing the principal remaining work. Refurbishment of the service and compressed-air systems also advanced materially, reaching approximately 90% completion.

Remaining work is concentrated in the grizzly and coarse-ore feed section, commissioning of the refinery (induction furnace), and final commissioning of the compressors, overhead cranes and standby power. Construction of the new compressor building is approximately 90% complete.

Maintenance work on the tailings storage facility (TSF) is expected to commence soon with a local contractor to be engaged shortly and supervised by Stantec's geotechnical engineer of record for the TSF.

The Company anticipates completing the balance of mechanical works and advancing into staged commissioning in Q4 2026 using existing stockpiles on site, subject to timely delivery of the leach-tank mechanisms and other long-lead items.
