GREAT PACIFIC GOLD PROVIDES WILD DOG PROJECT EXPLORATION UPDATE

Great Pacific Gold Corp. is providing an exploration update on drilling and fieldwork from its flagship Wild Dog project, located on the island of New Britain, Papua New Guinea (PNG).

Highlights from the main epithermal target area

1. Sinivit -- 3,000 metres of drilling in 2025 over 18 diamond drill holes with two high-grade ore shoots identified:
   1. Northern sulphide -- WDG-08: 8.4 metres at 50.1 grams per tonne AuEq (gold equivalent) (59.6 g/t Au (gold), 1.9 per cent Cu (copper), 59.6 g/t Ag (silver));
   2. Southern oxide -- WDG-02: 7.0 m at 10.9 g/t AuEq (5.5 g/t Au, 3.0 per cent Cu, 68.8 g/t Ag).
2. Kavasuki -- 1,000 metres of drilling in 2026 over seven diamond drill holes on one east-west section:
   1. Broad mineralized zone from surface -- KVH-03: 38.4 m at 2.23 g/t AuEq (2.4 g/t Au, 0.02 per cent Cu, 2.5 g/t Ag);
   2. Follow-up drilling is planned to test strike continuity to the north and south with six additional drill holes totalling approximately 900 metres.
3. Magiabe -- main vein and newly discovered west vein to be drilled following Kavasuki:
   1. Magiabe Main: historic drilling 4.4 m at 9.2 g/t Au, 37.9 g/t Ag;
   2. Magiabe West: 2026 channel sample: 8.0 m at 18.1 g/t AuEq.
4. Mengmut -- defined by high-grade surface geochemistry and historic drilling:
   1. Trench sampling 2026: 4.0 m at 2.5 g/t Au;
   2. Continuing exploration focused on refining drill targets along the broader Mengmut trend.
5. Morgan -- parallel structure to Sinivit target, expanded to 850 m strike length in 2026 mapping:
   1. 2026 channel sample: 19.3 m at 4.13 g/t AuEq (4.0 g/t Au, 0.03 per cent Cu, 6.0 g/t Ag).
6. EK target area:
   1. Elamaraka -- mapping confirmed multiple structurally controlled quartz-sulphide vein systems associated with widespread Au-Cu; historical trench six m at 4.40 g/t Au;
   2. Recent surface bench sampling returned 2.21 g/t Au, 10 g/t Ag and 0.05 per cent Cu across a six m exposed vein zone associated with sheeted quartz-pyrite and chalcopyrite veining;
   3. Kargalio -- mapping defined a 16 m wide north-south fault-shear corridor hosting quartz-pyrite vein material; historical trench six m at 11.9 g/t Au.

"The main epithermal target zone at Wild Dog continues to show district-scale potential with six main target areas distributed across approximately 4.5 km of interpreted epithermal vein structure planned for drill testing in 2026. The company is planning a further 10,000 metres of diamond drilling from May through December this year to systematically test these priority targets in the main epithermal target area. We are also continuing to advance emerging targets such as Kasie Ridge, where the first diamond drill hole is nearing completion, initial geological observations continue to support the broader exploration potential of the target area and a follow-up hole is planned. GPAC continues to be well financed through 2026 and beyond with our cash position at end of Q1 of approximately $26.3-million," stated Greg McCunn, chief executive officer.

"The recent work at Elamaraka and Kargalio continues to demonstrate the broader scale potential of the Wild Dog district beyond the currently defined Sinivit-Kavasuki mineralized system," stated Callum Spink, vice-president, exploration. "Importantly, the current exploration strategy is focused on systematically building a pipeline of structurally controlled drill-ready targets across the district through integrated geological mapping, trenching, geochemistry, MobileMT geophysics and structural interpretation. These emerging targets share many of the same geological and structural characteristics observed elsewhere across the broader Wild Dog district, including Sinivit, Kavasuki and Magiabe, and continue to support our interpretation that Wild Dog represents an underexplored district-scale epithermal mineralized system."

Quality assurance/quality control (QAQC)

The company follows industry-standard quality assurance and quality control (QA/QC) procedures for the collection, handling and analysis of exploration samples. Diamond drill core, rock-chip, trench, channel and surface bench samples referenced in this release were collected by Great Pacific Gold geological staff and submitted to Intertek Minerals Ltd. in Lae, Papua New Guinea, an ISO 9001-certified independent analytical laboratory with internationally recognized quality standards.

Diamond drill core (HQ and PQ diameter) was sawn in half, with one-half submitted for analysis. Surface samples were collected and documented in accordance with industry-standard exploration practices. Samples were dried, crushed and pulverized prior to analysis.

Gold analyses were completed by fire assay, while silver and copper analyses were determined using multielement methods following four-acid digestion (MS48) and ICP-OES/MS analysis.

Certified reference materials (standards), blanks and field duplicates were inserted into the sample stream at industry-standard frequencies, including routine insertion of blanks following mineralized intervals. All assay batches received to date have passed QA/QC review and fall within acceptable tolerance limits.

Core recoveries were within acceptable ranges, and sampling procedures and chain-of-custody protocols were managed by company geologists and field staff in accordance with industry best practices. Rock-chip, trench, channel and surface bench samples are selective in nature, and may not be representative of the underlying mineralized system.

Historical sampling and drilling results referenced in this release were completed by previous operators and have not been independently verified by the company. The company considers these results relevant for exploration targeting purposes only.

About Great Pacific Gold Corp.

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 interpreted to extend to depths exceeding 1,000 metres based on the 2025 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 two drilling rigs mobilized on site.
• Kesar project: Located in the Eastern Highlands province of PNG and contiguous with the mine tenements of K92 Mining Inc., the Kesar project is a greenfield exploration project with several high-priority targets in close proximity to 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, 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 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.

We seek Safe Harbor.
