Second Drill Rig to be Mobilized to Great Pacific Gold’s Wild Dog Project

September 9, 2025 – Vancouver, BC, Canada – Great Pacific Gold Corp. ("Great Pacific Gold," "GPAC," or

the "Company") (TSXV: GPAC | OTCQX: FSXLF | Germany: V3H) announces that it has commenced

mobilizing a second drill rig to 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 rig and crew are being

provided by Zenex Drilling, the Company’s drilling partner.

Key Highlights:

• District-scale epithermal Wild Dog structural corridor:

o 15 km epithermal structural corridor with geophysics indicating >1,000m verical

extent1.

• Outstanding high-grade drill intercepts to date2:

o WDG-08 - 8.4 m @ 49.9 g/t AuEq from 154m (46.5 g/t Au, 1.7% Cu, 66.3 g/t Ag), and

o WDG-02 – 7.0 m @ 11.2 g/t AuEq from 65m (5.5 g/t Au, 3.5% Cu, 68.8 g/t Ag).

• Large copper-gold porphyry potential at Magiabe1:

o Mobile MT geophysics defines a potential copper-gold porphyry target 1.5 km west of

the Wild Dog epithermal structure potentially 1,000 m in diameter and over 2,000 m in

depth.

• Current Phase 1 program only testing shalllow, potential open-pit mineralization on epithermal:

o Sinivit target 1.5 km stike length only 10% of epithermal, and

o Max target depth with current drilling only ~100 m.

• Second drill rig being mobilized to site to:

o Extend drilling at Sinivit to depth;

o Accelerate completion of currently planned 28 holes at Sinivit;

o Accelerate stepping out to the North to Kavasuki target, and

o Accelerate potential initial drilling at Magiabe porphyry.

“The current drill program success, along with the interpretation and analysis of the Mobile MT geophysics

data has given us confidence in accelerating our drilling program on both the epithermal and porphyry

targets at Wild Dog ,” stated Greg McCunn, CEO . “ The potential for significant mineralization at depth

below the current drilling at Sinivit is highly evident and continuing to step out North from Sinivit to the

Kavasuki target is high priority on the epithermal system. If all goes according to plan, we expect to have

the second rig up and running in early November.

There is still a significant amount of initial groundwork to be done prior to drilling at the Magiabe porphyry,

but having a second rig on site will allow us to prioritize the work as soon as we are ready.”

The high-grade results to-date from the current drill program at the Sinivit epithermal target are shown

in Figure 1. The Sinivit target is open to the North (toward Kavasuki target), at depth, and along strike to

the South.

Quality Assurance / Quality Control (QAQC)

The Company adheres to industry best practices for Quality Assurance and Quality Control. Drill core

samples were 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 was completed using fire assay with additional multi-element MS48 analysis

completed in Australia.

Diamond drill hole WDG -02 was drilled using a combination of HQ and PQ diameter core , while the

remainder of the holes were drill ed with PQ. 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 15km 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-02 which intercepted 7.0 meters a t 11.2 g/t AuEq from 65 m eters. The current drilling

program will extend into 2026 with 5,000 meters planned over 28 holes.

• 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 are working on developing a follow-up Phase

2 program for Q1 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.
