Walhalla Gold Project

The Walhalla-Woods Point Goldfield is one of Victoria, Australia's significant goldfields with an estimated total historic gold production from 54 mines of 2.2Mozs (72.2 tonnes) at a gold grade of 25.3g/t (Source: GeoVic, 2020), approximately 10% of the state's historic gold production. It is estimated that there are over 420 mines/workings for gold within the goldfield, which lies in the Palaeozoic-aged Melbourne geological structural zone, some 150km east of Melbourne.

About Great Pacific Gold

Great Pacific Gold's vision is to become the leading gold-copper development company in Papua New Guinea ("PNG"). The Company has a portfolio of exploration-stage projects in PNG, as follows:

• Wild Dog Project: the Company's flagship project is located in the East New Britain province of PNG. The project consists of a large-scale epithermal target, the Wild Dog structural corridor, stretching 15 km in strike length and potentially over 1,000 meters deep based on a recent MobileMT geophysics survey. The survey also highlighted the Magiabe porphyry target, adjacent to the epithermal target and potentially 1,000 meters in diameter and over 2,000 meters deep. Drilling of the epithermal structure on the Sinivit target has yielded high-grade results, including WDG-08 which intercepted 8.4 meters at 50 g/t AuEq from 154 meters. The current drilling program will extend into 2026 with second drill rig expecting to be operational in February 2026.

• Kesar Project: located in the Eastern Highlands province of PNG and contiguous with the mine tenements of K92 Mining Inc. ("K92"), the Kesar Project is a greenfield exploration project with several high-priority targets in close proximity to the property boundary with K92. Multiple epithermal veins at Kesar are on strike and have the same orientation as key K92 deposits, such as Kora. Exploration work to date by the Company at the Kesar Project has shown that these veins have high grades of gold present in outcrop and very elevated gold in soil grades, coincident with aeromagnetic highs. The Company conducted a diamond drill program on key target areas at the Kesar Project from November 2024 to May 2025 and have developed a follow-up Phase 2 program for 2026.

• Arau Project: also located in the Eastern Highlands province of PNG, the Arau Project is south of and contiguous to the mine tenements of K92. Arau contains the highly prospective Mt. Victor exploration target with potential for a high sulfidation epithermal gold-base metal deposit. A Phase 1 Reverse Circulation drilling program was completed at Mt. Victor in August 2024, with encouraging results. The Arau Project includes the Elandora licence, which also contains various epithermal and copper-gold porphyry targets.

The Company also holds the Tinga Valley Project in PNG.
