Guardian Exploration Concludes 2025 Field Work at Sundog Gold Project; Reports Preliminary High Grade Gold Results

Executive Summary

• Guardian completed its 2025 field program at the Sundog Gold Project, reporting multiple high‑grade gold intercepts up to 34.45 g/t Au from grab/chip samples and several channel samples exceeding 10 g/t Au.
• Significant expansion of known mineralized strike length was demonstrated: Trench 8 & 9B now show a combined strike of ~15.4 m (up from 8.8 m) and Trench 10’s vein‑hosted gold zone extended to at least 40 m (up from 15.5 m).
• The company plans an expanded 2026 exploration program that includes additional mapping, soil sampling, drone geophysics and diamond drilling to test depth and strike extensions identified in 2025.

Key Details

• Project Overview: Sundog property covers 94.15 km² within the Ennadai–Rankin Archean greenstone belt, a region hosting world‑class deposits such as Meliadine.
• Field Program Duration: 1 Sept – 7 Oct 2025; 248 rock samples collected (86 cut channel samples).
• High‑Grade Grab/Chip Results (selected):
• Sample 291593 (Trench 10) – 34.45 g/t Au
• Sample 291592 (Trench 10) – 20.177 g/t Au
• Sample 291600 (Trench 10) – 21.536 g/t Au
• Sample 291597 (Trench 10) – 22.231 g/t Au
• Channel Sampling Highlights:
• Trench 8, Channel 1 – 4.695 g/t Au over 96 cm interval.
• Trench 9B, Channel 2 – 8.851 g/t Au over 72 cm interval.
• Trench 10, multiple channels showing grades from 0.81 to 20.07 g/t Au; notably Channel 9 (20 cm) returned 20.072 g/t Au.
• Strike Length Extensions:
• Trench 8 & 9B: strike increased to ~15.4 m (previously 8.8 m).
• Trench 10: vein‑hosted gold zone now ≥40 m (previously 15.5 m).
• Geological Interpretation: Gold‑bearing veins hosted in competent mafic–intermediate sills with steep NNE–SSW brittle structures; potential for deeper eastward extensions and flat‑lying mineralized zones along high‑strain fabrics.
• QA/QC: Samples processed by Paragon Analytical Ltd. (ISO‑accredited) using PhotonAssay™; >0.5 g/t Au samples to be re‑analyzed by fire assay; selected high‑grade samples undergoing PhotonAssay‑to‑Extinction for statistical validation.
• Future Work (2026): Expanded geological mapping, soil sampling, additional trenching, drone‑based magnetic & radiometric surveys, and diamond drilling targeting depth extensions and newly identified strike zones.

Notable Quotes

“Our 2025 field work at Sundog has delivered encouraging results in a highly fertile gold field. The results confirm the presence of high‑grade gold, and visible coarse gold observed in the field supports our interpretation of a nuggety system.” – Graydon Kowal, President & CEO
