LaFleur Expands Swanson Gold Deposit System, Confirming Strong Continuity

LaFleur Minerals Inc. (CSE: LFLR, OTCQB: LFLRF, FSE: 3WK0) (“LaFleur Minerals” or the “Company”) is pleased to report results from its ongoing drilling program at the Swanson Gold Project, highlighting strong continuity of gold mineralization with significant widths and grades. The program targeted under-tested areas of the Swanson Gold Deposit and successfully intersected broad, continuous zones of gold mineralization that infill large gaps within the existing geological and mineral resource models, further confirming the potential for a large-scale gold system.

A total of seven (7) diamond drill holes were completed at relatively shallow depths, ranging from approximately 90 to 250 metres vertically, over a plunge length of approximately 200 metres (Figure 1). The holes were specifically designed to fill-in larger gaps in the previous drill data and to test the continuity of the Swanson Gold Deposit. Positive results confirm the continuity within and beyond the limits of the 2026 Mineral Resource Estimate and planned pitshell, confirming large-scale gold expansion with broad high-grade intercepts (refer to press release dated March 3, 2026).

Drilling Highlights:

• 2.95 g/t Au over 80.00 metres (SW-25-085)
• 2.37 g/t Au over 88.05 metres (SW-25-086)
• 1.29 g/t Au over 93.85 metres (SW-25-087)
• 0.86 g/t Au over 103.55 metres and 1.14 g/t Au over 56.65 metres (SW-25-090)

Drilling focused on previously untested areas between 90 and 250 metres vertical depth, where historical drilling was limited and spacing between holes exceeded 50 metres (Figure 2). The current program has significantly increased confidence in the continuity of mineralization both within and beyond the proposed pit shell at depth.

These broad intercepts include higher-grade sub-intervals, such as 232.00 g/t Au over 0.50 metres (SW-25-085), as well as 3.98 g/t Au over 9.00 metres and 7.78 g/t Au over 1.90 metres (SW-25-087). Visible gold on Swanson is not uncommon and was intersected in three (3) of the seven (7) recent holes (SW-25-081, SW-25-083, and SW-25-087), further supporting the potential for high-grade shoots within the system at depth (Figure 3). These observations, combined with assay results, provide valuable data for refining geological interpretations and guiding future drill programs. The results offer critical insight into the geometry and plunge of the mineralized zones, enhancing the Company’s understanding of the deposit. Mineralization remains open at depth and along strike, reinforcing the strong expansion potential of the Swanson system.

The success of this infill drilling program underscores the scale, width, and continuity of the mineralized system and will directly inform future targeting as LaFleur continues to advance the Swanson Gold Project. With these results, LaFleur continues to build significant momentum in 2026 as the Company advances toward the development of a scalable, district-wide gold production platform in Québec’s prolific Abitibi…
