Large Scale Epithermal System and Porphyry Potential Highlighted by MobileMT Survey at Great Pacific Gold's Wild Dog Project

Executive Summary

• Ongoing diamond drilling at the Wild Dog epithermal vein system intersected a high‑grade interval: 7.0 m @ 11.2 g/t AuEq (5.5 g/t Au, 68.8 g/t Ag, 3.1 % Cu) from 65 m (hole WDG‑02).
• MobileMT airborne EM survey delineates a ≥15 km strike length epithermal corridor extending >1,000 m depth and identifies a large (~1 km dia., >2 km deep) porphyry copper‑gold target at Magiabe, 1.5 km west of the vein system.
• Recent surface sampling at Magiabe returned strong porphyry pathfinder signatures (e.g., 2.5 g/t Au, 124 ppm Cu, 9.1 g/t Ag; 0.12 g/t Au, 0.25 % Cu, 5.6 g/t Ag). The company plans to advance Magiabe toward drill‑readiness in 2026.

Key Details

• Drill Intercept (Hole WDG‑02): 7.0 m @ 11.2 g/t AuEq (5.5 g/t Au, 68.8 g/t Ag, 3.1 % Cu) starting at 65 m depth.
• Epithermal System Extent: MobileMT data show a continuous conductive zone over ~15 km strike length, with depth penetration to ≥1,000 m.
• Magiabe Porphyry Target:
• Interpreted potassic core ≈1,000 m diameter, extending >2,000 m depth.
• Geophysical signature: strong resistivity and magnetic anomalies consistent with a large porphyry intrusion.
• Historic IP survey (2010) identified a ~200 m chargeability anomaly; 2025 MobileMT expands this to the full vertical/lateral extent.
• Surface Sample Assays (Magiabe Float, Feb 2025):
• Sample 30012 – 2.5 g/t Au, 124 ppm Cu, 9.1 g/t Ag, 24 ppm Mo.
• Sample 30008 – 0.12 g/t Au, 0.25 % Cu, 5.6 g/t Ag, 208 ppm Mo.
• Exploration Plan:
• Continue epithermal drilling through remainder of 2025 (current program tests ~10 % of structure).
• Elevate Magiabe work‑stream; detailed mapping, additional geochemical sampling, and possible ground geophysics in coming months.
• Target first drill testing of Magiabe porphyry system by 2026.
• Technical Oversight: Qualified Person – Callum Spink, VP Exploration (MAIG, NI 43‑101). QA/QC performed at Intertek Minerals Ltd., Lae, PNG; core recovery and assay protocols meet industry standards.

Notable Quotes

“The Wild Dog epithermal vein structure's high‑grade nature has been evidenced by the drilling results from our Phase 1 program to‑date… Magiabe represents a convergence of historical clues and modern exploration data all pointing to a significant porphyry copper‑gold deposit.” – Greg McCunn, CEO

Materiality Assessment: Material – Positive** (high‑grade drill intercepts and identification of a large porphyry target constitute material information likely to influence investor perception).
