South Pacific Metals Provides Project Updates

and Announces Diamond Drill Rig Purchase to

Accelerate Gold and Copper Exploration

Vancouver, British Columbia--(Newsfile Corp. - April 8, 2025) -

South Pacific Metals Corp.

(TSXV:

SPMC) (OTCQB: SPMEF) (FSE: 6J00)

("

SPMC

" or the "

Company

") is pleased to announce the

acquisition of its first man-portable diamond drill, following the successful close of its C$6.3 million

financing. Designed for efficient core drilling to depths of 500+ metres in remote locations, the new

MultiPower MP500 Diamond Core Drill can operate year-round and will support faster and more cost-

effective mobilization efforts across SPMC's 3,100 km² portfolio of four gold-copper projects in Papua

New Guinea.

Drill Rig Acquisition

The MultiPower MP500 Diamond Core Drill purchase enables the Company to accelerate early-stage

target testing of known high-grade gold and copper bearing structures. Equipment is scheduled to arrive

at the end of May, with drilling to begin soon after. Former K92 Mining Inc. ("

K92

") exploration

operator/manager, Dean Williamson, will assemble and lead the in-country drill crew who will transport,

set up, and operate the drill throughout the 2025 drilling campaign.

"

The acquisition of our first man-portable drill rig marks a major milestone in accelerating our

exploration efforts across Papua New Guinea

," said Michael Murphy, Executive Chair of the Company.

"

With a strong treasury following our recent financing, we're now in a position to aggressively advance

our gold and copper projects. The bulk of our identified drill targets fall well within the depth range of

this rig, allowing us to operate more efficiently and cut estimated drilling costs by nearly half. While

surface work continues to refine and expand our target pipeline, upcoming drill programs are

designed to test both known zones of mineralization and newly prioritized areas with strong potential.

We're confident this next phase will drive significant value across our portfolio

."

Osena Project

Focus remains on the Ontenu Cu-Au Prospect, a large-scale, multi-intrusive copper-gold porphyry, vein

and skarn complex extending over 5 km x 3 km. Field sampling

has commenced at Ontenu NE, which

has potential to host lode-gold style mineralization consistent with what K92 is now mining, as the

Company prepares to access the Ontenu Central prospect, which hosts confirmed gold-bearing

breccias and a large porphyry target ~250 m below surface. 3D geological and structural modeling to

assist with drill planning efforts is now complete. The primary targets are near-surface high-grade gold

structures, such as the structures hosting gold-bearing breccias — recent trench results from Ontenu

Central

include 79 m averaging 0.75 g/t Au, including 4 m at 4.52 g/t Au and individual samples

up to 8.82 g/t Au

(see news release dated

October 16, 2024

).

Anga Project

Additional surface exploration work, including more detailed soil grid sampling, planned at the Irinke

Prospect, has now defined a 2 km-wide mineralized NE trending corridor, with orientation and strike

continuations comparable to K92's Arakompa Discovery and lode-gold drill program less than 3 km

away. Recently, the Company completed a geochemical study, in respect of all surface samples

collected to date at Anga. This work has confirmed the Arakompa-like geochemical signature of the

Irinke target, providing vectors to further mineralization in the area and identifying new prospects that

warrant on-the-ground follow up. Drill program design continues to be assessed.

Kili Teke Project

With road access to the tenement and a nearby airfield, the project is situated just 40 km west of the

Porgera Gold Mine, a Barrick Gold Corporation and Zijin Mining Group joint venture. Thie Kili Teke

Project currently hosts an

Inferred Mineral Resource (as defined on only a portion — the Central

Porphyry — of the system) of 1.81 Moz Au, 802 kt Cu, and 40 kt Mo contained metal, in 237 Mt

at 0.34% Cu, 0.24 g/t Au &, 168 ppm Mo

(see

January 12, 2023

, press release and National

Instrument 43-101 ("

NI 43-101

") published report available on SEDAR+.

Following a successful Warden's Hearing on March 11, 2025, for licence renewal, the Company is now

focusing on landowner mapping and community engagement with the intention of commencing on-

ground exploration that prioritizes additional discoveries of high-grade Cu-rich skarn, higher grade

porphyries (Ieru Prospect) and Porgera-style gold targets and structures (Ridge Gold Prospect). High-

grade skarn was intercepted

by drilling of the previous operator returning 12.98% Cu, 11.75 g/t

Au and 21.07 g/t Ag over 7.8 m within 54 m @ 2.1% Cu, 1.82 g/t Au, 3.87 g/t Ag

(from 878 m depth

down hole)

2

. The Ridge Gold Prospect shows a Porgera alkalic-style metal signature (Au-Te-As), which

differs from that of resource porphyry (Cu-Au-Mo), and soils have returned up to 9.3 g/t Au. Work

completed by the previous operator at the Kili Teke Project included extensive diamond drilling of

approximately 36,000 m, primarily focused on the porphyry resource, at an estimated cost of US$20

million.

May River Project

The Skygate Cu-Au Trend, including the Skiraisa Gold Breccia Prospect ("

Skiraisa

") which lies within a

7 km long gold-copper mineralized trend just 15 km west of the giant Frieda River Cu-Au deposit, has

been prioritized for exploration. Historical drilling intercepts

include 109 m at 1.53 g/t Au from

surface

3

and 54 m at 1.83 g/t Au from 106 m depth

3

within Skiraisa, with several holes ending in

+1

g/t Au and up to 3.7 g/t Au

mineralization. Another important prospect warranting follow-up in the field

includes the Ufuo Prospect, a high-grade polymetallic massive sulfide system, from which historical

drilling returned exceptional results including

19 m @11.47% Cu, 2.17 g/t Au from 13 m depth and 11

m @ 10.07% Cu, 2.03 g/t Au from 13 m depth

About South Pacific Metals Corp

.

South Pacific Metals Corp. is an emerging gold-copper exploration company operating across Papua

New Guinea's proven gold and copper production corridors. With an expansive 3,100 km² land package

and four transformative gold-copper projects contiguous with major producers K92 Mining, PanAust and

neighbouring Barrick/Zijin, new leadership and experienced in-country teams, are prioritizing thoughtful

and rigorous technical programs focused on boots-on-the-ground exploration to prioritize discovery

across its portfolio projects: Osena, Anga, Kili Teke, and May River.

Immediately flanking K92's active drilling and gold producing operations to the northeast and southwest,

SPMC's Osena and Anga Projects are located within the high-grade Kainantu Gold District — each

having the potential to host similar-style lode-gold and porphyry copper-gold mineralization as that

present within K92's tenements. Kili Teke is an advanced exploration project situated only 40 km from

the world-class Porgera Gold Mine and hosts an existing Inferred Mineral Resource with multiple

opportunities for expansion and further discovery. The May River Project is located adjacent to the world-

renowned Frieda River copper-gold project, with historical drilling indicating potential for a significant,

untapped-gold mineralized system. SPMC common shares are listed on the TSX Venture Exchange

(TSXV: SPMC), the OTCQB Marketplace (OTCQB: SPMEF) and Frankfurt Stock Exchange (FSE:

6J00).
