South Pacific Metals Returns up to 12.8%

Copper from Outcrop Outside the Kili Teke

Resource; Massive Sulphide Traced over 200

Metres

Assays confirm mineralisation within a massive sulphide unit

mapped over more than 200 metres on the western margin of

the Central Porphyry. Two priority target areas outside the

current Mineral Resource are advancing toward drill-ready

status.

Highlights

Massive sulphide unit, mapped over 200 metres and open,

along a north-south fault contact

on the western margin of the Central Porphyry outside of the Mineral Resource boundary

strengthened by surface mapping and assays: outcrop samples returned 12.8% Cu, 0.30

g/t Au and 104 g/t Ag.

Historic trench mineralisation validated by new sampling.

Eight samples collected across

part of the historic trench were mineralised, averaging 0.36% Cu and 0.72 g/t Au.

Ridge Gold (Kwaki Creek area) remains a compelling geochemical target:

historic soils

returned up to 9,390 ppb Au (9.39 g/t Au) within a strong gold-in-soil anomaly, also elevated in

tellurium, indicating a potential alkalic, Porgera-style target.Previous drilling was oriented from the

north-to-south and did not effectively test the inferred south-dipping structures.

Further targeting focused at depth beneath the current Mineral Resource,

where historic

drilling includes 187 m at 1.10% CuEq (0.62% Cu, 0.44 g/t Au) from 501 m in KTDD022.

Additional 205 soil samples and 60 rock samples

pending assay

from current program.

Drill-ready targets expected in Q4 2026,

ahead of a planned maiden diamond drill program.

Vancouver, British Columbia--(Newsfile Corp. - August 31, 2026) -

South Pacific Metals Corp.

(TSXV:

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

SPMC

" or the "

Company

") is pleased to report first assay

results and field progress from the Kili Teke Copper-Gold Project ("

Kili Teke

") in Hela Province, Papua

New Guinea, held 100% through the Company's wholly-owned subsidiary Kainantu Resources Limited.

Kili Teke hosts a National Instrument 43-101 ("

NI 43-101

") Inferred Mineral Resource of 237 Mt grading

0.34% Cu and 0.24 g/t Au, equivalent to approximately

4.2 Moz AuEq

1

at 0.55 g/t AuEq or 3.14 billion

lbs CuEq at 0.60% CuEq

, within the Central Main Porphyry. More than 95% of historical drilling across

the 253 km

2

licence was concentrated on this single porphyry centre. The Company's current exploration

program is confirming historic work and identifying mineralised target zones outside the current mineral

resource envelope (see news release dated

June 25, 2026

).

The current work is prioritising two target areas outside the Mineral Resource (see news release dated

July 29, 2026

) - the Ieru (Yalopi formation) to the west of the Central Porphyry, including the massive

sulphide and trench zones, and Ridge Gold (Kwaki Creek area) to the east. Much of the preparatory

work required to convert them into drill-ready targets is now well underway. The current program

represents the first systematic exploration at Kili Teke in approximately a decade.

Timo Jauristo, CEO of SPMC, commented: "Kili Teke has been dormant for almost a decade, but the

opportunity here was never in doubt. Our first exploration program has already found further encouraging

evidence of strong mineralisation in several areas outside of historically drilled Central Porphyry. This

supports our view of Kili Teke as a broader porphyry/epithermal complex around the 4.2 Moz AuEq or

3.1 billion lbs CuEq Central Porphyry. Our focus now is on pulling this recent data together with the

historical dataset to define targets ready for drill testing by the end of October."

FIRST ASSAY RESULTS

The first-phase exploration program by SPMC is designed to map and sample the district surrounding

the Central Main Porphyry to identify and prioritise new drill targets outside the current Mineral Resource.

Forty-two rock samples collected during the initial site visit have been analysed for gold (Au), copper

(Cu), and silver (Ag), with full multi-element results pending. Selected results are presented in Table 1,

with results for all 42 samples provided in Appendix 1:

TWO PRIORITY TARGET AREAS DEFINED

The Yalopi formation, part of the Ieru prospective zone, lies west of the Central Main Porphyry

resource

and incorporates a large gold-in-soil anomaly, the historic Ieru trench and the newly mapped

massive sulphide unit described above. The historic trench returned

132 m at 0.55% Cu, 0.6 g/t Au

,

including

27 m @ 0.97% Cu, 1.25 g/t Au

. New sampling across part of the historic trench returned eight

mineralised samples averaging 0.36% Cu and 0.72 g/t Au, supporting mineralisation previously

identified in the area. Mapping is 70% complete and is documenting lithology, alteration and

mineralisation across the target area.

At the Kwaki Creek area, within the greater Ridge Gold area,

a priority target area east of the

Central Main Porphyry resource incorporates the very high tenor gold-in-soil anomaly. A

205

-sample soil

grid has been completed, while recent mapping identified further altered and mineralised outcrop,

including monzonite, on the northern flank of the ridge, consistent in type and style with mineralisation

already documented to the south. The target area is materially larger than it was previously understood to

be. Historic trenches on the southern flank have been relocated and resampled. This target is expected

to be defined by gridded soil geochemistry along with mapping.

The Company's initial focus will be generating drill targets outside of the historic resource area,

focused on Ieru-Yalopi and Ridge Gold-Kwaki areas.

FURTHER TARGETS AT DEPTH BENEATH THE MINERAL RESOURCE

Prior operator, Harmony Gold, completed approximately 37,500 metres of drilling at Kili Teke and

defined the current Mineral Resource within the upper part of a single porphyry centre (Central Main

Porphyry). Several of the longest and highest-grade intercepts recorded extend below the base of that

model, and a number of holes ended in mineralisation.

Selected historical intersections include higher-grade Cu-Au intervals reported at 0.8% Cu cut-off,

together with a broader mineralised interval in KTDD022 of 187 m @ 1.10% CuEq (0.62% Cu, 0.44 g/t

Au) from 501 metres. A high-grade skarn intersection in KTD025 of 8 m @ 13.31% Cu, 11.75 g/t Au

from 920 metres demonstrates mineralisation along the carbonate contact outside the current resource

model, in a hole that was not drilled to test a skarn.

Copper-equivalent (CuEq) is calculated as CuEq (%) = Cu (%) + 1.0815 × Au (g/t), using metal prices

of US$4.45/lb copper and US$3,300/oz gold and assuming equal metallurgical recoveries for both

metals - the same basis on which the Company reports its Inferred Mineral Resource. No allowance is

made for differential metallurgical recovery, though test work indicates that gold reports primarily to

copper concentrates in the porphyry system. Metal equivalents are presented for comparative

purposes only and do not represent a statement of economic viability. Cu and Au grades are rounded

for presentation; CuEq is calculated from unrounded values. Historic results generated by prior

operator Harmony Gold. All intervals are downhole lengths; true widths are not known.

Octavio Garcia, Exploration Manager of SPMC, commented: "What stands out from this first program is

that the geology is telling us the same story from two independent directions. On the western side we

have strong outcrop exposure in the creek beds, including sulphide mineralisation we can trace along

strike for a couple of hundred metres, which gives us real confidence in that area even before the

balance of the assays are back. The eastern side is different - the outcrop is there, but Ridge Gold will

be defined more by soil geochemistry than by what we can see at surface, so the two areas will mature

differently. The best information is coming from the bottom of deep creeks, which will be a challenge for

drilling but is not impossible. Our priority now is turning this into a properly ranked, structurally-informed

drill target inventory."

THE MINERAL RESOURCE

Kili Teke hosts an NI 43-101 Inferred Mineral Resource of 237 million tonnes, defined by Harmony Gold

within the upper part of the Central Main Porphyry alone, inside the broader 253 km² licence:

reported at a 0.2% Cu cut-off above 780 m RL. See the November 18, 2022 technical report for assumptions and estimation methodology. For

indicative comparison, SPMC calculates the contained Au and Cu as approximately 4.2 Moz AuEq using US$3,300/oz Au and US$4.45/lb Cu and

assumed equal recovery of Au and Cu. Molybdenum is excluded. This AuEq figure is not the basis of the Mineral Resource Estimate; drawn from

the independent technical report dated November 18, 2022, prepared by Graeme J. Fleming, B.App.Sc., MAIG, and available under the Company's

profile on SEDAR+ at

www.sedarplus.ca

.

Gold-equivalent and copper-equivalent grades are calculated at US$3,300/oz gold and US$4.45/lb

copper assuming equal recoveries for both metals, as disclosed in the Company's news release

dated July 29, 2026. No allowance is made for differential metallurgical recovery, though test work

indicates that gold reports primarily to copper concentrates in the porphyry system. Metal equivalents

are presented for comparative purposes only and do not represent a statement of economic viability.

Cu and Au grades are rounded for presentation; CuEq is calculated from unrounded values. Historic

results generated by prior operator Harmony Gold. All intervals are downhole lengths; true widths are

not known.

The resource is reported on both a gold-equivalent and a copper-equivalent basis as Kili Teke is a bi-

metallic asset: a meaningful gold inventory and a meaningful copper inventory in the same deposit, and

neither presentation alone describes it fully.

NEXT STEPS

Further samples have been collected, including 205 soil samples and 60 rock samples, with assay

results to be reported once received and validated.

Geochemical analysis integrating new field results with the historical datasets - to test for

mineralisation outside the Central Porphyry.

A LiDAR and airborne magnetic survey to support structural interpretation and drill planning.

Collection of additional structural data required to define drilling parameters.

Finalisation of alteration, lithology, structural, mineralisation assemblages and their interpretation.

Follow-up on several other targets identified in the surrounding area.

The Company anticipates being in a position to define drill-ready targets within the two priority areas by

the end of October 2026. Further field campaigns are planned, the scope of which will depend on the

outcome of the current assessment and which will include further mapping and sampling of the two main

targets, as well as other targets. Further details will be announced in due course.

Quality Assurance and Quality Control

All rock samples are collected on site by the Company's geology team and surveyed using hand-held

GPS. Samples are shipped to Intertek Laboratory in Lae, Papua New Guinea. Gold is assayed by 50 g

fire assay with AAS finish (FA50/AA); copper and silver are assayed by 3-acid digest with AAS finish

(PGGA03) at Intertek Lae. Only the initial assaying for Au-Cu-Ag is reported in this release. Sample

pulps are subsequently sent to Intertek in Perth, Western Australia, for multi-element ICP-MS analysis

using a 4-acid digest (4A/MS); the ICP-MS multi-element work is pending for all samples noted in this

release. The Company's procedures require the insertion of two certified reference materials

(standards), one blank and one duplicate within each batch of 100 samples to monitor laboratory

performance.
