9.5 metres @ 13.8 g/t AuEq Intercepted at Great Pacific Gold's Wild Dog (12.61 g/t Au, 0.62% Cu, 14.63 g/t Ag)
Vancouver, December 10, 2025 - Great Pacific Gold Corp. (TSXV: GPAC) (OTCQX: GPGCF) (FSE: V3H) ("Great Pacific Gold," "GPAC," or the "Company") announces results from its expanded Phase 1 diamond drill program at its flagship Wild Dog Project ("Wild Dog" or the "Project"), located on the island of New Britain, East New Britain Province, Papua New Guinea ("PNG"). The Phase 1 program is focused on the Sinivit target, a portion of the 15 km Wild Dog epithermal structural corridor.
Key Highlights:
- WDG-14 intercepted:
- 9.5 m @ 13.8 g/t AuEq from 200.77 m (12.61 g/t Au, 0.62% Cu, 14.63 g/t Ag);
- including: 3.9 m @ 32.16 g/t AuEq from 204.3 m (29.62 g/t Au, 1.39% Cu, 31.25 g/t Ag).
- Second drill rig scheduled to arrive in late January, enabling expanded drilling coverage across the 15 km Wild Dog structural corridor.
- Camp expansion and new site infrastructure is nearing completion, positioning GPAC for a significant ramp-up in drilling activity in 2026.
"Our geological confidence continues to strengthen as each drill hole refines the plunge, geometry, and true width of the northern sulphide zone. WDG-14 has delivered one of the most coherent and strongly mineralized intervals drilled at Wild Dog to date. The textures, sulphide intensity, and grade profile align exceptionally well with our growing model for a large, well-endowed epithermal system. Since commencing drilling in May, we have built a full exploration team, established critical infrastructure, and developed strong community support. With a second rig arriving in late January 2026 and several high-priority targets ready for testing, Wild Dog is positioned for an exciting and transformative year in 2026," stated Callum Spink, VP Exploration.
Wild Dog Phase 1 Diamond Drill Program
The Phase 1 program commenced in May 2025 and is designed to test the Sinivit target, a 1.5 km strike length within the 15 km Wild Dog epithermal vein structural corridor (Figure 1). The high-grade nature of the system has already been confirmed by multiple strong intercepts.
In addition, MobileMT geophysical data has highlighted the exceptional scale of the epithermal system and the potential for a major porphyry copper-gold system adjacent to the veins - a setting analogous to the Wafi-Golpu deposit in PNG (mineralization at Wafi-Golpu is not necessarily indicative of mineralization at Wild Dog).
The expanded program now totals 28 diamond drill holes and is expected to continue into early 2026. A second drill rig is in the process of being mobilized to site.

Notes:
- Drill highlights presented above are core lengths (true widths are not known at this time).
- Gold equivalent (AuEq) exploration results are calculated using longer-term commodity prices with a copper price of US$4.50/lb, a silver price of US$27.50/oz and a gold price of US$2,000/oz. No metallurgical testing has been carried out on Wild Dog mineralized samples. For AuEq calculations, recovery assumptions of Au 92.6%, Ag 78.0%, and Cu 94.0% were used based on K92 Mining's stated recovery results in an Updated Definitive Feasibility Study for the Kainantu mine.
WDG-13 Overview
WDG-13 tested the south-western strike extension of the Wild Dog epithermal vein system. The hole intersected two distinct quartz-sulphide vein and breccia zones, confirming structural continuity and extending mineralization along the projected corridor.
Zone 1 intercepted 5.10 m @ 3.38 g/t Au, 8.20 g/t Ag, 0.23 % Cu (3.83g/t AuEq) from 134.50-139.60 m, and featured:
- Fractured to brecciated quartz-sulphide veining
- Crack-seal banding indicating repeated hydrothermal pulses
- Fine sulphide selvages with local chalcopyrite
Zone 2 (201.9 m to 204.6 m) was a narrower interval with strong brittle deformation and reflects the distal edge of the deeper mineralized shoot.
WDG-14 Overview
Hole WDG-14 was drilled as a deeper down-plunge step-out beneath WDG-08 to test the projected continuation of the high-grade shoot within the northern sulphide zone. The hole intersected the structure at the anticipated depth and orientation, returning one of the strongest mineralized intervals recorded at Wild Dog to date.
WDG-14 Main Vein Intercept:
- Thick quartz-pyrite-chalcopyrite mineralization
- Hydrothermal brecciation with sulphide-rich matrix
- Local bornite and chalcopyrite veinlets indicating strong fluid flow

The technical content of this news release has been reviewed, verified and approved by Callum Spink, the Company's Vice President, Exploration, who is a member of the Australian Institute of Geoscientists, MAIG, and a Qualified Person as defined by National Instrument 43-101 Standards of Disclosure for Mineral Projects. Mr. Spink is responsible for the technical content of this news release. Mr. Spink is not independent of the Company.
Quality Assurance / Quality Control (QAQC)
The Company adheres to industry best practices for Quality Assurance and Quality Control. Drill core samples were sawed into equal halves and the selected one-half core was submitted to Intertek Minerals Ltd. in Lae, Papua New Guinea, an ISO 9001-certified laboratory. Samples were securely sealed in poly-weave bags with single-use tie-locks to maintain chain of custody. Analytical testing is completed using fire assay for gold, preliminary copper and silver assays are reported from results generated by aqua regia digestion and atomic absorption (AA) copper determination. The results are updated with assay results using MS48 (multi-element 4-acid digestion ICP/AA).
Diamond drill hole WDG-02 was drilled using a combination of HQ and PQ diameter core, while the holes WDG-03 to WDG-09 were drilled with PQ. Holes WDG-10 onwards were drilled with HQ diameter core. Certified reference materials (standards) and blanks were inserted into the sample stream in accordance with industry-standard protocols. Blanks were routinely inserted after high-grade intervals, and certified standards were included at a frequency of at least 5%. All assay batches received to date have passed QAQC review and fall within acceptable tolerance limits. Core recoveries for all holes were within acceptable ranges, with sampling procedures carefully managed in intervals where ground conditions were variable or fragile.
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 metres 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 metres in diameter and over 2,000 metres deep. Drilling of the epithermal structure on the Sinivit target has yielded high-grade results, including WDG-08 which intercepted 8.4 metres at 50 g/t AuEq from 154 metres. The current drilling program will extend into 2026 with second drill rig expecting to be operational in late January 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 sulphidation 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.
