Signature releases field program results, amends loan

Executive Summary

• Signature Resources released detailed surface sampling results from its Spring Field Program (May 2025) across five zones at the Lingman Lake gold project, highlighting multiple intercepts ≥0.10 g/t Au and several high‑grade grab samples up to 9.91 g/t Au.
• The program adds significant new geological insight that will guide future drill targeting and geophysical work.
• The company amended its related‑party loan, extending maturity to 30 Sept 2025 and increasing the principal to $350,000 (interest‑free), providing interim financing for ongoing operations.

Key Details

• Program Scope: 111 surface samples collected across five target areas within the Lingman Lake property.
• Area 1 (North Zone): 13 channel cuts over a 14‑m transect; two northern samples returned 0.14 g/t Au and 0.21 g/t Au; one grab sample yielded 8.26 g/t Au near a historic 11.52 g/t Au channel sample.
• Area 2 (South–11650 Zone): Seven channel samples, with two longer cuts (0.8 m & 1.0 m) returning 0.24 g/t Au and 0.54 g/t Au; three grab samples in the south zone returned 0.67 g/t Au, 4.31 g/t Au, and 9.91 g/t Au.
• Area 3 (South Zone Projection): Follow‑up to 2024 drill holes LM 24‑09 & LM 24‑10 (1.81 g/t Au over 51 m; 1.80 g/t Au over 34 m). Surface channel samples north of the trough returned low grades, confirming weathered exposure.
• Area 4 (Central Zone B): Eleven channel cuts across a 4‑m wide outcrop; four samples graded 0.11–1.63 g/t Au; prior 2024 sample had shown 5.45 g/t Au and a small cut of 2.31 g/t Au, indicating a new surface target.
• Area 5 (Inter‑Zonal Corridor): Two north‑south transects (42 samples total) across a 33‑m width; eight samples returned 0.13–1.27 g/t Au; complex QFP dike/sill network noted, warranting detailed mapping.
• Overall Findings: ~25% of all samples ≥0.10 g/t Au; high‑grade grab results (up to 9.91 g/t Au) demonstrate the presence of discrete mineralized pockets at surface. Results will directly influence drill hole placement and geophysical targeting.

Loan Amendment

• Amended Related‑Party Loan:

• Repayment Plan: Anticipated repayment through future equity financings.
• Compliance: Loan meets TSX Venture Exchange Policy 5.9 and MI 61‑101; subject to exchange approval.
