GPAC Completes Spin Out of Walhalla Gold Corp.

December 12, 2025 – Vancouver, BC, Canada – Great Pacific Gold Corp. ("Great Pacific Gold," "GPAC," or

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

previously announced Plan of Arrangement in connection with the spin out (the “Spin Out”) of Wa lhalla

Gold Corp. (“Wa lhalla”), whereby Great Pacific Gold will distribute the shares of Walhalla to the

shareholders of GPAC (the “Shareholders”). Walhalla owns the Walhalla Gold Project in Victoria, Australia.

The Spin Out was implemented under the terms of an arrangement agreement (the “Arrangement

Agreement”) among the Company , 1537559 B.C. Ltd. (“Finco”) and Walhalla , pursuant to which the

Shareholders will receive: (i) one (1) common share of Walhalla for every Class A Common Share in the

Company held (the “Class A Share”); and (ii) one new common share of the Company (the “New GPAC Share”)

for every Class A Share held.

As a result of the Spin Out, the Shareholders of the Company ceased to be holders of the Class A Shares so

exchanged, and the Class A Shares were cancelled by the Company. Each Shareholder became a Shareholder

of Walhalla, subject to the amount of Class A Shares held by that Shareholder, and Walhalla became a

reporting issuer in the Province of British Columbia.

In addition, Finco previously made a one- time payment of $1,500,000 to the Company under the

Arrangement Agreement. Prior to Walhalla listing on the Canadian Securities Exchange, Walhalla will acquire

all of the issued and outstanding shares of Finco. The Company also retains a 2% net smelter return royalty

on the Walhalla Gold Project.

The New GPAC Shares will be listed on the TSXV at the market opening on December 16, 2025.

Walhalla has applied to list its common shares on the Canadian Securities Exchange and the listing of

Wahalla remains subject to acceptance of the Canadian Securities Exchange.

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 met ers 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 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 sulf idation 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.
