Great Pacific Gold Provides Wild Dog Project Update

April 3, 2025 – Vancouver, BC, Canada – Great Pacific Gold Corp. ("Great Pacific Gold," "GPAC,"

or the "Company") (TSXV: GPAC | OTCQX: FSXLF | Germany: V3H) is providing an update on its

exploration activities at the Wild Dog Project (“Wild Dog” or the “Project”), located on the island

of New Britain, in the province of East New Britain, Papua New Guinea ("PNG”), Figure 1.

Key Highlights:

• A MobileMT geophysics helicopter-borne survey is currently being flown over a 187km2

area (1,030 line-km) across the Wild Dog Proje ct with 200-meter line spacing and 2,000-

meter tie-lines. The survey is currently approximately 30% complete.

• Drilling contract signed with Zenex Drilling and a dual -purpose ( DD & RC ) drill rig is

expected to be deliver ed to East New Britain on April 22, 2025 . Drilling is planned to

commence in early May.

• A NI 43 -101 compliant technical report has been completed by RSC which provides a

comprehensive review of historical work carried out on the Project and recommend s

the Phase I drilling program be focused on a 3km section of the Wild Dog epithermal vein

structure (Figure 1).

• Phase I drill program proposed to consist of 10 diamond drill holes , spaced at 200 -250

meter intervals along a north -northeast-striking line from the South Oxide Zone to the

Kavasuki Zone for a total of 3,000 meters and an additional 4 diamond drill holes testing

the important north- northwest-trending structures for an additional 1,800 meters

(Figure 2).

• Camp and core storage facilities have been established in the community of Rieit with a

Project Manager, technical team and support staff in place.

• Successful community celebration was held on March 29 th with over 5,000 people in

attendance and support from local, provincial and federal government officials.

"Wild Dog is a project of tremendous potential and a potential company-maker for Great Pacific

Gold,” commented Greg McCunn, CEO. "We are very grateful for the warm welcome we received

from the Baining and Tolai people of East New Britain and the wonderful hospitality of the

community of Rieit in hosting a kick-off celebration last weekend. Exploration activity has been

ramping up at the Project during Q1, and Q2 is set to be an exciting time with the geophysics set

for completion and Phase I drilling set to commence. We look forward to delivering some exciting

results from the first modern exploration program carried out on this district-scale land package.”

Callum Spink, VP Exploration of GPAC, commented: "The launch of our first drill campaign marks

a significant step in unlocking the project's potential. With historical intercepts indicating high-

grade gold, this program is aimed at confirming and extending those results, building the

foundation for a compliant resource and broader district-scale exploration success."

Wild Dog MobileMT Geophysics Survey

The survey marks a significant milestone in exploration at Wild Dog and is a key step toward

enhancing the Company’s understanding of the area’s structural and lithological framework

controlling high -grade gold and copper minerali zation throughout the 11 km -long Wild Dog

structural corridor (Figure 1).

Wild Dog hosts several advanced high-sulphidation and low-sulphidation epithermal gold-copper

targets, including the previously mined Sinivit deposit and the Kavasuki vein system. In addition,

porphyry Cu-Au targets at Magiabe and Mt Regess have now been confirmed as high pr iority

targets through recent follow-up work.

The NI 43-101 Technical Report (March 31, 2025) highlights the significant upside of the Wild Dog

Project, with widespread high-grade surface geochemistry, strong alteration systems, and results

of up to 127 g/t Au in trench samples at Kavasuki. Previous exploration has been limited by deep

tropical weathering, and widespread shallow ash cover – making airborne geophysics the most

efficient means to unlock the district’s full potential.

The MobileMT survey is designed to:

• Define large-scale structures and alteration zones beneath ash cover;

• Delineate potential feeder systems and porphyry-style mineralization at depth; and,

• Refine priority targets for Phase I and II drilling programs.

”Launching this survey is a pivotal milestone for GPAC,” commented Callum Spink, VP Exploration

of GPAC. “MobileMT gives us a unique window into the deep structural framework of Wild Dog,

particularly beneath the ash cover that obscures much of the geology. We’re excited to generate

new targets and rapidly advance this highly prospective, underexplored district.”

The towed “bird” is suspended approximately 30 metres below the aircraft. It houses the

MobileMT receiver and sensors used to measure natural electromagnetic fields.

station records natural electromagnetic field variations at ground level, providing critical

reference data to enhance the accuracy and resolution of the airborne MobileMT survey.

Community Celebration

Great Pacific Gold thanks all the wonderful Baining and Tolai people of East New Britain as well

as the settlers and visitors who attended the important cultural celebration held on March 29th

in Rieit, East New Britain Province. Company personnel enjoyed celebrating with the community

to kick-off the 2025 exploration program.

GPAC is honoured to also have toured the project area this weekend with leaders from various

local governments and landowners as well as federal and provincial government officials. The

project, as it advances, is uniquely situated to provide significant benefit to the local communities

in terms of economic development and employment opportunities.

NI 43-101 Compliant Technical Report

Great Pacific Gold commissioned RSC to prepare an independent technical report (the “Report”)

in compliance with National Instrument 43-101: Standards of Disclosure for Mineral Projects (NI

43-101) and Form 43-101F1, in respect of the Wild Dog Project in East New Britain Province, PNG.

The purpose of the Report is to provide a comprehensive review of the historical work carried

out on the Project and to make recommendations for an exploration program that is expected to

commence in Q2 2025.

The Report documents all scientific and technical data and data collection processes for the

Project. No current mineral resource estimate exists for the Project. The Report has an effective

date of 31 March 2025 and will be filed on SEDAR+ and the Company’s website imminently.

Property Description & Ownership

The Project is located approximately 50 km south -southwest of Rabaul on the northeastern

slopes of the Baining Mountains of the Gazelle Peninsula, East New Britain Province, Papua New

Guinea. The Wild Dog Project consists of two exploration licenses (EL 2516 or ‘Wild Dog’, and EL

2761 or ’Gunsap’), which total 1,424 km2. Gunsap (EL 2761) was granted to a wholly -owned

subsidiary of GPAC (Wild Dog Resources) on 27 June 2023 and is subject to renewal on 27 June

2025. Wild Dog (EL 2516) was granted to a private company called Munga River Limited (MRL)

on 22 April 2024 and is subject to renewal on 22 April 2026.

Geology & Mineralization

The Gazelle Peninsula is dominated by a series of north-northwest-striking normal faults, known

as the Baining Mountain Horst and Graben Zone (Madsen and Lindley, 1994). During the early

Miocene, ash flow tuff volcanism of the caldera margin -related Nengmutka Volcanics was

localized along this extensional zone (Madsen and Lindley, 1994). Basement rocks in the Gazelle

Peninsula, and throughout New Britain, comprise Late Eocene and Late Oligocene volcaniclastic

formations (the Baining Volcanics and Merai Volc anics, respectively), typical of an embryonic

island arc, and intruded by dioritic plutons. Two contrasting structural regimes are recognized,

with the older existing at the time of initial mineralization at the Wild Dog Project during the early

Miocene, and a subsequent period of extensional tectonism that has persisted from early

Miocene to the present.

The early Miocene structural pattern at Wild Dog is reflected by vein-filled and silicified structures

known as the Nengmutka Vein System. The ~2.6-km-long central portion of the Wild Dog Project

area is dominated by two north- northeast-trending sub- parallel structures that are variously

(hydrothermal) clay -covered or host outcropping veining and silicification. This ~1 - km-wide

structural corridor (the ‘Sinivit - Gunsap Mountain structural corridor’) represents the

predominant structure, with a strike of a t least 10 km. A fault jog, which trends 330 –340°,

connects the partially exhumed northern end of the Sinivit structure with the southern end of

the Gunsap Mountain structure, and indicates the operation of a sinistral shear duplex at the

time of initial Au-Cu vein-hosted mineralization during the early Miocene.

Four hydrothermal vein types and two hydrothermal episodes have been recognized in the Sinivit

and Kavasuki deposits, which represent the most advanced (and previously mined for oxide gold

(Au) mineralized material at Sinivit from 2007– 2013) project areas at Wild Dog. These episodes

include an early low -sulphidation stage and a late high -sulphidation stage (Lindley, 1990).

Epithermal vein textures suggest that Au was deposited as a result of pressure release and boiling

of hydrothermal fluid localized by a major fault structure. Gold mineralization is best developed

near local cross structures. Later mineralization fills open fractures and cavities in the quartz veins

as dark sulphide stringers comprising copper (Cu) sulphides (chalcopyrite with minor bornite,

chalcocite, and tennantite), with local occurrences of a wide variety of Cu- Bi-Pb-Ag sulphide,

telluride, and selenide minerals. Gold typically occurs as Au-Ag telluride minerals, with native Au

also present within the weathering profile.

In addition, limited historical work by several previous owners of the Project (drainage mapping

and sampling, assaying and airborne magnetics and induced polarization (IP) survey

interpretations) has identified at least two potential porphyry Cu- Au targets (Magiabe and Mt

Regess) within two kilometer s of the epithermal Au- Cu vein -hosted mineralization at Sinivit.

Precursory exploration by previous owners suggests that these dioritic intrusions may represent

the causative plutons for epithermal vein-hosted Au-Cu identified at Sinivit, Kavasuki, and several

other early-stage prospects along the Sinivit– Gunsap Mountain structural corridor.

Although there is as yet no guarantee that the Project will yield a potentially large Cu -Au (-Mo)

deposit, the Qualified Person’s (QP; Frank Bierlein) site visit in February 2025 confirmed that

mining was carried out in the past at Sinivit, and that Cu mineralization was readily visible in

outcrop, float, and check samples collected by the QP . The QP also sighted (and sampled)

exposures of the altered Magiabe diorite, yielding disseminated pyrite and chalcopyrite, as well

as evidence for incipient breccia q uartz-sulphide veining. Geochemical analysis (by Intertek

Laboratories) of 24 check samples collected by the QP (Frank Bierlein) from Sinivit and Kavasuki

confirm the presence of anomalous concentrations of Au (<84 ppm) and Cu (> 95,240 ppm) in

many of these samples.

History

Mineralization in the Sinivit area was first identified by Fisher and Noakes (1942), who reported

trace amounts of Au in the main streams draining the Baining Mountains. In 1983, Esso Papua

New Guinea Inc. (Esso) discovered the ‘Wild Dog’ (herein referred to as ‘Sinivit’) Au deposit after

a 14-month program, comprising detailed sampling and mapping in a 90- km2 area between the

Nengmutka and Rapmarina rivers. Between 1983 and 2012, various owners carried out a range

of exploration programs over the wider Project area, as well as >25,000 m of diamond coring and

nearly 24,000 m of shallow percussion drilling at Sinivit and Kavasuki. New Guinea Gold

Corporation (NGG), which acquired the rights to the Sinivit property in 2002, operated a relatively

www.gpacgold.com | 7

unsuccessful and likely unprofitable shallow open -pit oxide Au mine at Sinivit from late -2007 to

mid-2013. Since that time, the historical mining and new license application area has not been

subjected to further exploration.

Conclusions & Recommendations

Historical production from the Sinivit Au operation was relatively limited and on a small scale.

However, the widespread presence of chalcopyrite, bornite, chalcocite, and covellite (+ reported

tellurides, tennantite, Bi -sulphosalts, and selenides), strong argillic, phyllic and colloform–

pervasive silicic alteration over strike distances of >2.6 km, together with individual Au assays of

up to 127 g/t from trenching at Kavasuki (Motton, 2023), and evidence for multiple hydrothermal

pulses associated with structural movements, all point to the potential existence of a significant

Au-Cu mineraliz ing system at Sinivit and Kavasuki. Sporadic exploration by previous owners

throughout the broader Project area has included reconnaissance mapping along ridges, spurs,

creeks, and streams, as well as geochemical sampling, alteration studies, and (limited) airborne

geophysical surveys. This work led to the recognition of several additional target zones, including

the Kavasuki epithermal vein deposit and the Magiabe and M t Regess porphyry Cu -Au

occurrences. However, confirmation of the Project’s exploration upside, and ability to host

potentially economic mineralization, will require funding and resources to open access tracks and

rock exposures, drill- test targets, and undertake systematic geological mapping, structural

investigations, and geochemical assaying of well-documented samples. The presence of a 2–3 m

thick veneer of volcanic ash, which covers ~70% of the Wild Dog –Gunsap Mountain structural

corridor, and deep tro pical weathering significantly affects the application of standard

exploration methods and their effectiveness in the steeply incised and rugged region

encompassed by GPAC’s two exploration licenses (EL 2516 and EL 2761).

To this end, the NI 43-101 Report prepared by RSC includes several recommendations for a two-

phase exploration program at Wild Dog. These recommendations are broken down into a Phase

I and a subsequent Phase II work program, whereby the decision to proceed with Phase II is

critically dependent on the success of the Phase I program. The total time frame for the

completion of both phases is approximately 15–24 months from the commencement of Phase I.

Phase I is designed to validate historical findings for the Sinivit and Kavasuki areas, which are

known to host epithermal Au mineralization . Lessons learned from the greatly improved

understanding of these highest- priority target areas can then be applied to a more broad -scale

approach that considers targeting and testing of historically identified areas, both along the

Sinivit–Gunsap Mountain structural corridor and further afield. This includes the targeting of

porphyry Cu-Au mineralization at Magiabe, Mt Regess, and other early -stage intrusive-related

prospects.

Phase I Potential Drill Plan

Key to an improved understanding of the minerali zed system and determining the upside

potential of the Project, is a well- planned and executed Phase I drilling program. The QP

recommends that such a drill program:

1. Be focused on the Sinivit and Kavasuki high-priority target areas, and

2. Comprises six and four orientated diamond drillholes, respectively.

These drillholes should be spaced at between ~200 to ~250 m intervals along a roughly north -

northeast-striking fence line and to a depth of up to 300 m, for a total meterage of 3,000 m. The

aim of this programme is primarily to verify and validate historical findings by the ‘twinning’ of

some historical drillholes that intercepted the Sinivit vein system and reported significant Au

intercepts (i.e. >2 g/t Au; Taylor, 2011), evaluate the down -dip extension and continuity of

mineralization, and acquire critical information regarding lithology, structure, veining, Au

mineralization and alteration from both oxidised and fresh host rocks. The azimuth of previous

drilling was predominantly orientated west to east (090°) and west-northwest to east-southeast

(120°), as it was aimed at intercepting the steeply west -dipping, north-northeast-trending Wild

Dog structure. The QP (Frank Bierlein) recommends the same drill direction (i.e. to 120°), at a dip

of -60° for the proposed Phase I program.

Given the importance of the spaced north -northwest-trending and moderately to steeply

southwest-dipping linking structures on the siting of mineraliz ation the QP (Frank Bierlein) also

recommends directing an additional four - 60° inclined drillholes towards an azimuth of ~050°,

and to a depth of 300 m at Sinivit, with two similarly positioned holes at Kavasuki, for an

additional 1,800 m of diamond drilling (Figure 3).
