Vancouver, British Columbia--(Newsfile Corp. - February 4, 2026) - LaFleur Minerals Inc. (CSE: LFLR) (OTCQB: LFLRF) (FSE: 3WK0) ("LaFleur Minerals" or the "Company") is pleased to announce drilling assay results from 12 validation drill holes completed at its Swanson Gold Deposit, as well as 28 additional regional exploration drill holes on the larger property. To date, LaFleur Minerals has reported results for 60 drill holes totalling 16,592 metres during its maiden drilling program in 2025. The validation drilling at LaFleur Minerals' Swanson Gold Project has confirmed strong gold continuity, long mineralized intercepts, and new shallow discoveries beyond the current Swanson Deposit footprint, reinforcing Swanson's potential as a scalable, district-scale gold asset. These results significantly enhance the Project's development thesis, support the forthcoming Preliminary Economic Assessment ("PEA") anticipated to be released in the next month, and positions Swanson as a long-term source of mill feed for the Company's nearby Beacon Gold Mill.

SUMMARY OF VALIDATION ASSAY RESULTS

The validation drilling has confirmed the size, continuity, and widespread nature of gold mineralization at the Swanson Gold Deposit. Significant assay intersections include:

• 2.05 g/t Au over 158.25 metres (SW-25-066)

• 1.15 g/t Au over 80.3 metres (SW-25-073)

• 1.37 g/t Au over 80.8 metres (SW-25-074)

• 2.97 g/t Au over 66.0 metres, including 91.1 g/t Au over 1.5 metres (SW-25-075)

• 3.15 g/t Au over 51.4 metres, including 92.9 g/t Au over 0.75 metres (SW-25-077)

SUMMARY OF REGIONAL EXPLORATION ASSAY RESULTS

The regional exploration drilling has intersected shallow gold mineralization outside of the Swanson Gold Deposit, showcasing the potential of additional open-pit gold deposits on this vast property. Significant assay intersections include:

• 1.58 g/t Au over 11.05 metres (SW-25-040)

• 0.67 g/t Au over 7.45 metres (SW-25-041)

• 5.78 g/t Au over 2.05 metres (SW-25-042)

• 1.41 g/t Au over 6.00 metres (SW-25-046)

VALIDATION DRILLING PROGRAM

The validation drilling program was undertaken as part of the data verification process in preparation for the Company's upcoming PEA and Technical Report completed in accordance with National Instrument 43-101 ("NI 43-101"). The validation drilling at the Swanson Gold Project has delivered compelling technical information that provides a foundation to establish an estimate of the deposit's scale, continuity, and economic relevance, materially strengthening confidence in both the geological model and the Project's development pathway.

The drilling program has confirmed the presence of broad, continuous, near-surface gold mineralization, returning multiple long intercepts with consistent gold grades, highlighted by 2.05 g/t Au over 158.25 metres, with narrow high-grade results including 121.0 g/t Au over 1.1 metres that assist to de-risk the Project and strengthen its development thesis and open-pit potential. Importantly, the drilling addressed key limitations in the existing resource model by connecting previously discontinuous mineralized zones and infilling large gaps outside the current pit shell. These outcomes are expected to improve mineral resource classification, and reduce projected strip ratios, providing a stronger technical basis for the forthcoming PEA and positioning Swanson as a credible, long-term source of mineralized material for the Company's nearby, fully-permitted Beacon Gold Mill, which is nearing production restart.

The drilling program at the Swanson Gold Deposit comprised 12 drill holes totalling 2,619 metres (refer to Table 1 and Table 2 for details). The primary objectives of the program were to:

• Validate historical drilling data to increase confidence in the geological model and mineral resource classifications;

• Confirm the continuity and scale of the mineralized system and assess the potential for further expansion;

• Collect drill core material for ongoing density measurements, ore-sorting and metallurgical test work; and

• Provide key data to refine deposit interpretation and enhance the current Mineral Resource Estimate, supporting the delivery of a technically robust PEA as the Company continues to expand its land package and known resources.

The drill holes were positioned as close as possible to historical drill hole locations and within the limits of the proposed pit shell. Target selection was based on a preliminary assessment of parameters likely to influence the economic viability of a potential open-pit mining operation (Figure 1).

The Swanson Gold Deposit benefits from an extensive historical database, including more than 36,000 metres of drilling across 242 drill holes. This historical work outlines broad zones of mineralization as well as numerous high-grade, significant intercepts. The majority of historical drilling within the proposed pit limits was completed by Lac Minerals (1982-1987), Phoenix Matachewan Mines (2003), and Agnico Eagle Mines (2006-2011).

The drilling program is intended to confirm the continuity of the high-grade shear zones identified in the current Mineral Resource Estimate as part of the data verification process for the PEA. In addition, the program addresses gaps in the existing resource model by connecting previously discontinuous zones of mineralization where historical sampling was limited or absent. This work has the potential to improve estimates of total contained gold ounces and reduce the projected strip ratio.

REGIONAL EXPLORATION DRILLING ACTIVITIES

In addition to the Swanson Gold Deposit validation drilling, the Company has been actively advancing exploration programs across the broader Swanson Gold Project. The Company is currently reporting on an additional 28 regional exploration drill holes, totalling 6,617 metres:

• Regional greenfield exploration across the Swanson property, which comprises more than 459 claims covering approximately 18,300 hectares;

• Drilling to verify and test the continuity of historical mineral showings

• Drill test targets developed from the 2025 regional explorations programs including airborne geophysics, ground IP, soil Geochem and prospecting.

• Best results from the most recent regional exploration holes by LaFleur, were in the area of the Jackson Showing discovered in 1932. The Jackson Showing is located approximately 6.2 km to the SW of the Swanson Deposit, proximal to the same regional NE-SW trending fault structure that is adjacent to the Swanson Gold Deposit. All four holes drilled by LaFleur in the area of the Jackson showing intersected shallow, near surface mineralization that included; 1.58 g/t Au over 11.05 metres (SW-25-040), 0.67 g/t Au over 7.45 metres (SW-25-041), 5.78 g/t Au over 2.05 metres (SW-25-042) and 1.41 g/t Au over 6.00 metres (SW-25-046) (refer to Table 3 and Table 4 for details). Additional drilling will be warranted by the Company to determine if such a shallow deposit could represent a viable satellite deposit capable of providing additional feed to the Beacon Gold Mill.

VAL D'OR REGION: AN AREA RICH IN GOLD BUT RARE IN CUSTOM MILLING OPTIONS

The Val-d'Or region, located within Québec's prolific Abitibi Gold Belt, is one of the most richly endowed gold districts globally, hosting numerous past-producing mines and a dense concentration of advanced exploration and development projects. The area surrounding LaFleur Minerals' Beacon Gold Mill is particularly prospective, with multiple nearby deposits reporting meaningful gold assays, including projects operated or advanced by Cartier Resources, Abcourt Mines, Amex Exploration, Radisson Mining, Probe Gold, among others. Despite this abundance of high-quality gold deposits, the region faces a significant shortage of available milling and processing infrastructure, creating a bottleneck for advancing many projects into production. The Beacon Gold Mill's strategic location, fully permitted status, and refurbishment underscore the urgency and opportunity to restart gold production, positioning the mill as a critical hub capable of supporting nearby satellite deposits and unlocking regional gold ounces that currently lack a viable path to production.

SAMPLING, QAQC, AND LABORATORY ANALYSIS SUMMARY

All core logging and sampling completed by LaFleur Minerals as part of its diamond drilling program is subject to a strict standard for Quality Control and Quality Assurance (QAQC), which include the insertion of certified reference materials (standards), blank materials, and field duplicate analysis. NQ-diameter sawed half-core samples from the drilling program at Swanson were securely sent by Company geologists to AGAT Laboratories Ltd. (AGAT), with sample preparation in Val-d'Or, Québec and analysis in Thunder Bay, Ontario, where samples were processed for gold analysis by 50-gram fire assay with an atomic absorption finish. Samples from selected holes were securely sent to AGAT in Calgary, Alberta, for multi-element analysis (including silver) by inductively coupled plasma (ICP) method with a four-acid digestion. AGAT sample preparation and laboratory analysis procedures conform to requirements of ISO/IEC Standard 17025 guidelines and meet the requirements under NI 43-101 and CIM best practice guidelines. AGAT is independent of LaFleur Minerals.

WORK IN PROGRESS

The Company is continuing diamond drilling in the area of the Swanson Deposit, which includes exploration drill holes below the current extent of the holes on the Swanson Deposit, as well as fill-in larger gaps within the limits of the current mineral resource.

The Company has also resumed regional exploration drill holes, particularly in the southeast and east parts of the property.

Additional drilling assay results will be released once available.
