Receives $1.5 Million Cash Payment

Vancouver, British Columbia--(Newsfile Corp. - June 23, 2025) - Great Pacific Gold Corp. (TSXV: GPAC) (OTCQX: FSXLF) (FSE: V3H) ("Great Pacific", "GPAC" or the "Company") is pleased to provide an update on the previously announced spin out (the "Spin Out") whereby Great Pacific will distribute the shares of a new company named Walhalla Gold Corp. ("Walhalla") to the shareholders of Great Pacific. Walhalla will then own the Walhalla Gold Project in Victoria, Australia¹ (See News Release May 2, 2025).

Transaction Highlights:

• Immediate Shareholder Value: Through this strategic spin out, GPAC shareholders will receive one share of Walhalla Gold for every GPAC share held.
• Cash Proceeds Secured: GPAC has received the $1.5 million cash² payment associated with the transaction.
• Definitive Agreement: GPAC, 1537559 B.C. Ltd. ("Finco") and Walhalla have entered into a definitive arrangement agreement setting forth the terms the Spin Out.
• Strengthened Strategic Focus: Cash payment received represents non-dilutive funding to focus on GPAC's high-impact Wild Dog Project in Papua New Guinea.
• GPAC Shareholders Retain Upside Exposure: Share ownership in a highly prospective new vehicle, Walhalla Gold Corp:
  • High-Grade Historical Production: The Walhalla Gold Project in Victoria, Australia, boasts a prolific history of production-1.51 million ounces at an average grade of 33.59 g/t Au (GeoVic, 2020).³
  • Walhalla District-Scale Potential: The 1,400 km² land package hosts a range of advanced-stage and greenfield targets, including the fully permitted and drill-ready Pinnacles target.

"The spin-out of Walhalla enables GPAC shareholders to retain full and direct exposure to a district-scale gold project in a proven jurisdiction, marking another step in delivering on GPACs objective to monetize non-core assets," said Greg McCunn, CEO of Great Pacific Gold. "The incoming funds continue to provide non-dilutive capital to advance our maiden drill program at Wild Dog in Papua New Guinea. Early results at Wild Dog (10.8 g/t AuEq over 7.0 metres from WDG-02 and 8.6 g/t AuEq over 6.0 meters from WDG-04), confirm high-grade, near-surface potential and we look forward to announcing further results from Wild Dog in the coming weeks."

Walhalla Gold Project

Located in the state of Victoria (Figure 1), the district-scale Walhalla project consists of over 1,400km² of concessions. In addition to multiple areas with past historic production, Walhalla contains a high-priority greenfield target called Pinnacles. Extensive soil geochemistry at Pinnacles has highlighted a 400m x 1,100m gold mineralized aplitic dyke which contains disseminated sulphides and outcrops at surface (Figure 2). The Pinnacles target is fully permitted, accessible, and ready for immediate drilling.

Project Highlights:

• History of gold production, with total historic production of 1,510,309 ounces at a grade of 33.59 g/t gold (GeoVic, 2020) at the Walhalla mine.
• Large (1,400km²) land package comprising numerous occurrences and historic mines hosting epizonal-style Au mineralization, most with no modern drilling and exploration.
• Cohen's Reef: historic production from laminated quartz veins within a single mineralized shoot down to 1,120m. Historic drilling at depth suggests multiple shoots and extensions (e.g. 4.25m @ 11.15 g/t Au from 258.4m).
• Longfellows Reef: Located 1 km west of and parallel to Cohens Reef, comprises of old gold workings over a strike length of 1.5km. Grab samples from the main adit returned 200m @ 4.95 g/t Au and 75m @ 4.1 g/t Au.
• Pinnacles: A 400m by 1,100 m zone of sulphide mineralization associated with disseminated sulphide in aplitic dykes and quartz stockwork veins in silicified sedimentary rocks. Highlight channel sampling includes 81.6m @ 1.02 g/t Au and 18.0m @ 3.28 g/t Au.

About Great Pacific Gold

Great Pacific Gold has a portfolio of exploration-stage projects in Papua New Guinea ("PNG"). The Company is focused on developing gold-copper resources from its highly prospective land packages. Its core projects include:

• 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 near 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.

• Wild Dog Project: located in the East New Britain province of PNG, the Wild Dog Project is a brownfield exploration project with a history of small-scale gold mining. The Wild Dog Project contains numerous epithermal, and porphyry hydrothermal-magmatic targets evidenced by previous exploration and operations. The Company completed a road refurbishment in August 2024 and baseline environmental work in Q4 2024. In Q1 2025, the Company began preparing for a drilling program with camp and infrastructure being established, airborne geophysics (MobileMT) survey completed and a geological team in place. A first phase of diamond drilling is underway on the property.

• Arau Project: located in the Eastern Highlands province of PNG, the Arau Project 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.
