5.9 meters @ 14.4 g/t AuEq Intercepted at Great Pacific Gold’s Wild Dog
November 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 15km Wild Dog epithermal structural corridor.
Key Highlights:
• WDG-12 intercepted two well mineralized structures:
o First Structure: 5.9 m @ 14.38 g/t AuEq from 123.2m (14.0 g/t Au, 0.18% Cu, 12.4 g/t Ag);
o Including: 2.5m @ 32.0 g/t AuEq from 126.6m (31.3 g/t Au, 0.28% Cu, 24.7 g/t Ag).
o Second Structure: 5.8 m @ 6.15 g/t AuEq from 177m (5.1 g/t Au, 0.54% Cu, 15.4 g/t Ag);
o Including: 3.0 m @ 10.9 g/t AuEq from 179m (9.1 g/t Au, 0.96% Cu, 28.5 g/t Ag).
• WDG-13 complete d and intersected two minerali zed zones characterised by quartz– sulphide
veining and brecciation. Assay results are pending, and WDG-14 is currently in progress, targeting
depth and strike extensions of the same structural corridor (see Figures 5 and 7).
• Second drill rig mobilization update: the second drill rig (dual purpose sonic / diamond) has been
shipped and is on route to the project site. Camp construction for the expanded drilling crew is
well underway with drilling expected to begin in December 2025.
• LiDAR survey results received: The program generated a Digital Terrain Model with sub- 10 cm
vertical accuracy, providing critical topographic control for geological modelling, drill planning,
and infrastructure layout. The dataset is currently being further analyzed and used to support
structural mapping and refine target definition across the broader Wild Dog district.
"The Sinivit target on the Wild Dog epithermal structural corridor continues to deliver high-grade results.
In addition, we are starting to build an advanced understanding of the structural controls for
mineralization at Sinivit. Holes WDG-08, 12 and 13 define a coherent high-grade pod within the broader
Sinivit structure, with WDG-14 underway and continuing to test this area. Mineralization beneath the
Northern Oxide area (10, 10A and 11) appears weaker, consistent with our current model and historical
results. This variation is typical of epithermal systems near surface,” stated Greg McCunn, CEO of GPAC.
“We are looking forward to the second drill rig arriving so we can begin testing the Sinivit area at depth as
well as exploring some of the other high- priority epithermal targets that have been identified in the
recently completed Mobile MT data analysis exercise.”

WDG-12 Overview
Drill hole WDG- 12 intersected two discrete zones of intense quartz –sulphide brecciation and veining
hosted within strongly altered volcanic rocks of the Wild Dog corridor. The upper interval (123 –129 m)
comprises colloform to crustiform quartz –pyrite–chalcopyrite–sphalerite–tennantite veins with
associated vuggy silica. The lower interval (177–183 m) consists of a clast-supported hydrothermal breccia
with quartz–sulphide cement and strong chalcopyrite –pyrite mineralization, interpreted to represent a
deeper boiling zone within the epithermal system. Both zones display clear structural control along steep,
northeast-trending faults consistent with the Sinivit vein orientation and suggest multiple mineraliz ing
pulses derived from a deeper magmatic source.
Zone 1 – High-Grade Epithermal Vein Zone
The first structure in WDG-12 intercepted a 5.9 m interval grading 14.38 g/t AuEq from 123.2 m, including
2.5 m @ 32.0 g/t AuEq from 126.6 m. This zone is characterised by banded quartz–sulphide veining, hosted
within silicified volcanic breccia. The textures display colloform and crustiform quartz banding, with
abundant sulphide -rich breccia zones indicating multiple pulses of hydrothermal fluid and localised
boiling, features typical of the high-grade epithermal veins developed along the Sinivit structural corridor.
Figure 1: WDG-12 core from 125.37–128.92m (Zone 1) showing high-grade quartz–sulphide veins and gold
grades up to 68.2 g/t Au.
Zone 2 – Quartz–Sulphide Breccia
The second mineralized zone in WDG-12, from 179.0–182.54 m, returned 5.8 m @ 6.15 g/t AuEq (5.1 g/t
Au, 0.54% Cu, 15.4 g/t Ag), including 3.0 m @ 10.9 g/t AuEq (9.1 g/t Au, 0.96% Cu, 28.5 g/t Ag). The interval
comprises a strongly mineralized quartz–sulphide breccia, with gold and copper values reaching up to 29.8
g/t Au and 3.1% Cu.
This section is dominated by clast-supported hydrothermal breccia cemented by chalcopyrite, pyrite, and
quartz, crosscut by later quartz–pyrite–chalcopyrite veins. Textural evidence suggests multiple phases of
brecciation and fluid reactivation, reflecting sustained hydrothermal activity and pressure cycling within
the feeder system. The zone potentially represents a deeper, high-temperature structural conduit within
the Sinivit system, where boiling and fluid mixing led to efficient precious and base metal deposition.

Coarse sulphide bands, comb quartz textures, and carbonate infill confirm a structurally controlled feeder
environment beneath the main Sinivit lodes.

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.
Drilling to date has only tested a small portion of the mineralized corridor, which remains open to the
north, south, and at depth. A second drill rig is in the process of being mobilized to site.

LiDAR Survey
A high-precision fixed-wing airborne LiDAR and large-format imagery survey covering 187 km² across the
Wild Dog district was completed in September 2025. The program produced a sub -10 cm Digital Terrain
Model (DTM), providing exceptional topographic contro l for geological modelling, drill planning, and
infrastructure design.
Following the recent delivery of the raw LiDAR dataset, GeoCloud Analytics has been engaged to
reprocess and interpret the point -cloud data from a geological perspective , enhancing the visibility of
www.gpacgold.com | 5
subtle surface features that are often smoothed out in standard “bare- earth” models. This work aims to
identify historical artisanal workings, map structural lineaments, fault zones, bedding and intrusive
contacts, and highlight potential new target areas for field verification.
The reprocessed products will include enhanced hillshades, structural interpretations, and shapefiles of
mapped geological features across the Wild Dog district, forming a key foundation for upcoming mapping
and drill-target generation. Current drill pad locations and drill traces on the LiDAR topography are shown
in Figure 6.

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 met ers deep.
Drilling of the epithermal structure on the Sinivit target has yielded high- grade results, including
www.gpacgold.com | 8
WDG-08 which intercepted 8.4 meters at 50 g/t AuEq from 154 m eters. The current drilling
program will extend into 2026 with second drill rig expecting to be operational in December 2025.
• 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
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.
