LaFleur Expands Swanson Gold Deposit System, Confirming Strong Continuity with 2.95 g/t Au over 80.00 metres and 2.37 g/t Au over 88.05 metres

Executive Summary and Key Details

• LaFleur Minerals reported significant gold mineralization results from its ongoing diamond drilling program at the Swanson Gold Project on May 12, 2026.
• Seven completed drill holes intersected broad, continuous zones of gold mineralization over plunge lengths of approximately 200 metres.
• Key intercepts include SW-25-085 (2.95 g/t Au over 80.00 m) and SW-25-086 (2.37 g/t Au over 88.05 m).
• Visible gold was intersected in three of the seven recent holes, reinforcing potential for high-grade shoots within the system at depth.
• Mineralization remains open at depth and along strike beyond current pit shells.
• Over 22,500 metres of diamond drilling completed on the Swanson property to date.

Evaluation of News Impact

• The drilling results validate the Preliminary Economic Assessment (PEA) released in March 2026 which projected an NPV of C$101 million and IRR of 65%.
• Confirming continuity beyond current pit shells supports the long-term mine life required to justify the C$30 million Trafigura prepayment facility announced in April 2026.
• The results are consistent with previous drilling announcements from February, March, and April 2026 which also reported broad intercepts (e.g., SW-25-066: 2.05 g/t over 158m).
• As a follow-up to the PEA and financing milestones, this news is expected rather than unexpected market-moving information.
