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)
December 10, 2025 – Vancouver, BC, Canada – Great Pacific Gold Corp. ("Great Pacific Gold," "GPAC," or
the "Company") (TSXV: GPAC | OTCQX: GPGCF | Germany: V3H) announces results from its expan ded
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:
o 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);
o 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 sup port. 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.

1. Drill highlights presented above are core lengths (true widths are not known at this time).
2. 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 minerali zed 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

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 h ave 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 K9 2. 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
