Great Pacific Gold Provides Wild Dog Drilling Update:

Kavasuki KVH-03 Completed Following Up KVH-01 58.9 m @ 2.50 g/t AuEq;

Kasie Ridge Drilling Intersects Hydrothermal Veining with Visible Chalcopyrite

(2.50 g/t AuEq = 2.43 g/t Au, 2.75 g/t Ag, 0.02% Cu – see notes at end of release)

March 11, 2026 – Vancouver, BC, Canada – Great Pacific Gold Corp. ("Great Pacific Gold," "GPAC," or the

"Company") (TSXV: GPAC | OTCQX: GPGCF | Germany: 0B3) is pleased to provide an update on ongoing

exploration drilling from its Wild Dog Project, located in East New Britain Province, Papua New Guinea.

Two drill rigs are currently active at Wild Dog. Drilling continues at the Kavasuki epithermal gold vein

system, while a second rig is conducting the first-ever drill test of the Kasie Ridge copper-gold target along

the 15 km Wild Dog Structural Corridor (Figure 1).

Kavasuki Highlights:

• KVH-01 intersected 58.9 metres @ 2.50 g/t AuEq from 38.6m (2.43 g/t Au, 2.75 g/t Ag, 0.02% Cu),

o including 4.6 metres @ 8.56 g/t AuEq from 49.0 m (8.24 g/t Au, 10.19 g/t Ag, 0.13% Cu)

• And 18.1 metres @ 2.14 g/t AuEq from 100.6 m (2.08 g/t Au, 1.60 g/t Ag, 0.03% Cu)

(See news release March 3, 2026, for more information)

• KVH-03 completed and intersected strong silica flooding and multi -phase quartz veining from

approximately 5 m to 51 m downhole

Kasie Ridge Highlights:

• KAS-01 drilling has intersected hydrothermally altered bedrock beneath the advanced argillic

lithocap

• Strong propylitic alteration with visible chalcopyrite and hydrothermal veining encountered from

approximately 50 m depth

• Portable XRF readings support visual identification of chalcopyrite within vein material (laboratory

assays pending)

“Drilling continues to advance at Kavasuki following the strong initial result from KVH-01, which returned

58.9 metres at 2.5 g/t AuEq near surface,” said Callum Spink, Vice President Exploration. “Drill hole KVH -

03 has now been completed, and geological logging confirms strong silica flooding and multi-phase quartz

veining consistent with the mineralized system we are targeting. With this hole complete, drilling has now

progressed to KVH-04 as we continue testing the geometry and continuity of the Kavasuki vein system.

At the same time, our first drill hole at Kasie Ridge has now penetrated beneath the advanced argillic

lithocap and intersected strong propylitic alteration with visible chalcopyrite. While still very early in the

hole, observations to date indicate hydrothermal alteration beneath the lithocap which is considered

encouraging in the context of the Company’s exploration model. We are excited to continue advancing this

hole to depth to properly test the target, and we look forward to providing further updates as drilling

progresses and assays are received.”

The Wild Dog Project hosts a 15 -kilometre-long structurally controlled mineral corridor containing

multiple epithermal gold targets and porphyry copper-gold potential identified through recent MobileMT

geophysical surveys.

The corridor contains the Sinivit –Kavasuki vein system and multiple advanced targets including Kasie

Ridge, which are now being systematically drill tested as part of the Company’s 2026 exploration program.

historical and recent work. Long section looking west highlights the approximately 3 km strike extent of

the Sinivit–Kavasuki area within the broader 15 km corridor.

Kavasuki Drilling Update

The Kavasuki vein system extends over approximately 900 metres of strike length and forms part of the

broader Sinivit –Kavasuki mineralized corridor, which represents roughly 3 km of the 15 km Wild Dog

Structural Corridor. Three diamond drill holes have been completed, with a fourth hole underway (Figures

2 and 3).

The Company recently reported strong initial results from drill hole KVH-01 which returned:

• 58.9 metres @ 2.50 g/t AuEq from 38.6m (2.43 g/t Au, 2.75 g/t Ag, 0.02% Cu), including

o 4.6 metres @ 8.56 g/t AuEq from 49.0 m (8.24 g/t Au, 10.19 g/t Ag, 0.13% Cu).

• And 18.1 metres @ 2.14 g/t AuEq from 100.6 m (2.08 g/t Au, 1.60 g/t Ag, 0.03% Cu).

See the Company news release dated March 3, 2026, for details.

Mineralization is hosted within multi -phase hydrothermal quartz breccia containing sulphid es including

pyrite, chalcopyrite and minor bornite, consistent with a structurally controlled epithermal vein system.

Drill hole KVH-03 has now been completed, with geological logging identifying strong silica flooding and

multi-phase quartz veining from approximately 5 m to 51 m downhole. Detailed logging and sampling

are currently underway (Figures 4 and 5).

KVH-03 was designed to test the west-dipping structural interpretation of the Kavasuki vein system

following structural measurements obtained from earlier drilling. Drill targeting will continue to be

refined as geological information from the current program is integrated.

Drilling has now progressed to KVH-04, which is being drilled from the same pad and designed to test

beneath the KVH-03 intercept. The close spacing of these holes is intended to better constrain the

structural controls on mineralization, evaluate short-range grade and structural continuity within the

vein system, and assess potential grade variability commonly observed in epithermal gold systems.

Kasie Ridge – First Drill Test Beneath Lithocap

The Company is providing an initial update from the first drill hole currently underway at the Kasie Ridge

target within the Wild Dog Project.

The first hole, KAS -01, has now penetrated through the upper clay -dominant portion of the advanced

argillic lithocap. Geological logging to date indicates propylitic alteration characterised by chlorite, epidote

and magnetite, with narrow epidote–quartz veinlets observed within volcanic host rocks.

Localized visible chalcopyrite has been observed during preliminary core logging ( Figures 6 and 7 ).

Portable XRF measurements support the visual identification of copper-bearing sulphides; however, these

readings are preliminary field -screening data only and are not a substitute for laboratory geochemical

assays. No quantitative copper grades are being reported from portable XRF data.

These early observations indicate hydrothermal alteration beneath the lithocap and are considered

encouraging in the context of the Company’s exploration model.

Drilling of hole KAS -01 remains ongoing , and geological logging and sampling will continue as the hole

advances. Further updates will be provided once the hole is completed and laboratory analytical results

are received.

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,

www.gpacgold.com | 8

stretching 15 km in strike length, with geophysical data suggesting significant depth extent. 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 the second drill rig now operational.

• 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 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 sulph 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.
