Great Pacific begins drilling at Kasie Ridge target

Executive Summary

• Great Pacific Gold Corp. has commenced drilling at the Kasie Ridge target on its Wild Dog project in Papua New Guinea, marking the first drilling ever undertaken at this specific location.
• A second diamond drill rig has arrived on site, allowing the company to run two rigs simultaneously (Rig 1 at Kavasuki and Rig 2 at Kasie Ridge) to increase exploration pace in 2026.
• Kasie Ridge is identified as the largest preserved advanced argillic alteration system on the project, interpreted as a lithocap above a potential high-sulphidation epithermal or porphyry system, with significant geological indicators including high-temperature minerals and structural convergence.

Key Details

• Drilling Status: First drill program at Kasie Ridge is underway; Rig No. 2 has arrived and commenced drilling. Rig No.1 is also active at the Kavasuki target with a second hole under way.
• Target Geology: Kasie Ridge is the largest preserved advanced argillic alteration system on the Wild Dog project, extending 1.5 to 2.0 km in strike and several hundred meters in width.
• Mineralogy: Alteration assemblage includes pyrophyllite, dickite, kaolinite, alunite, diaspore, and zunyite, indicating high-temperature, acidic hydrothermal conditions.
• Geophysical Data:
  • Coincident magnetic anomaly interpreted as hydrothermal modification of a shallow magnetic source.
  • MobileMT and resistivity inversions define conductive clay-rich zones with localized deeper resistive features (potential silica-rich or structurally focused zones).
  • Structural interpretation highlights multiple north-northwest/northwest-trending lineaments converging beneath the ridge.
• Drill Hole Details: First hole, KAS-01, was collared within the highest-temperature portion of the advanced argillic assemblage. It is designed to test the intersection of two conductive lineaments, evaluate the margin of a moderately conductive upflow zone, and assess vertical alteration zonation and sulphide development.
• Strategic Context: The company plans to increase the pace of exploration in 2026 with two rigs operating full-time.
• Comparable Districts: Geological comparisons provided for Lepanto (Philippines), Wafi-Golpu (PNG), and Onto (Indonesia) to illustrate potential for concealed mineralization beneath lithocaps.
• Wild Dog Project Overview: The flagship project features a 15-kilometer structural corridor. Previous drilling at the Sinivit target yielded high-grade results, including WDG-08 (8.4m at 50 g/t AuEq from 154m).
• Other Projects:
  • Kesar Project: Greenfield exploration with high-grade gold in outcrop/soils; Phase 2 drill program planned for 2026 following Nov 2024–May 2025 drilling.
  • Arau Project: Phase 1 RC drilling completed at Mount Victor in Aug 2024 with encouraging results.
  • Tinga Valley Project: Held in PNG.

Notable Quotes

• "Kasie Ridge is a very technically compelling target on the Wild Dog project. The scale of advanced argillic alteration, the presence of high-temperature minerals such as zunyite and diaspore, and the convergence of structural corridors into a coincident magnetic feature all point toward a robust hydrothermal centre. Lithocap systems are inherently high risk, but they are also where many major high-sulphidation and porphyry discoveries originate. This drill program is about applying disciplined mineral systems thinking to test whether we are positioned above something significant," stated Callum Spink, vice-president, exploration.
• "Drilling with rig No. 1 is also progressing well with a second hole under way at the Kavasuki target. Having two rigs turning full-time will allow us to increase the pace of our exploration in 2026, as planned."
