Initial Surface Trenching Results

The Company interprets that the Ontenu Prospect at surface is the upper part of a significant gold-copper porphyry system.

Trench 1 is a 79 m long, east-west oriented channel excavated to a depth of 1 to 1.5 metres (see Figure 1). This trench targeted an area associated with high tenor gold in soils (between 80-360 ppb Au) over a line-length of 260 m. The exposed rocks in the trench revealed weathered gossanous material and was mapped as a combination of microdiorite, diorite porphyry and diorite breccia. The trench was oriented E-W and is proximal to mapped silica ledges and feldspar-hornblende porphyries intruding the sampled microdiorite. Stockwork veins and gossanous material (iron oxides from weathering of sulphide material) were mapped in the trench. The area has not been previously drilled, and based on regional interpretation, may link along a WNW-ESE striking structural corridor to a gold-in-soil anomaly (80 to 210ppb Au) located 300m to the ESE. The area to the north (and northwest) of Trench 1 has not yet been soil sampled by the Company. Further, many rock samples peripheral to Ontenu's core area returned high grade results that warrant following: Regional rock samples returned up to 2.69 g/t Au, 71.3 g/t Ag, 0.26 %Cu, and 5.3 %Zn.

Soil sampling was designed to complement two soil lines previously collected by the Company in 2022 (see news release dated March 23, 2023). Soils were collected at a nominal 50 m spacing along E-W lines with 100 metres spacing between lines. Nearly the entire area sampled, over 1 km by 800 m has highly anomalous gold in soils. The peak soil assay result returned was 1,560 ppb Au (1.56 g/t Au). As evidenced by high tenor gold in soils on the last lines of the soil survey, the soil anomaly is likely to continue farther to the west, north and south of the current area sampled.

The Company anticipates reporting full results, including review and interpretation of all assays and historical data in September 2024.

About the Osena Project

Covering 626 km² of strategic ground, the Osena Project is located southwest of and adjacent to K92's tenements that host the Kainantu Gold Mine. Priority prospects include Ontenu, a porphyry copper-gold and epigenetic gold prospect with exposed porphyritic diorite intrusive phases hosting supergene copper minerals, and overprinted by a later gold mineralized event associated. The Ontenu Prospect is one of many occurring within a highly mineralized corridor that extends more than 40 km northeast across the Kainantu District.

Quality Assurance and Quality Control

All Ontenu samples were collected under previous management, with the samples securely stored in the Kainantu office of the Company for the past year, prior to being sent to the laboratory for assaying.

Trenching and Rock Sampling

Trench samples are collected from a hand-excavated trench to a depth of approximately 1 m. The trench wall and floor is mapped and a representative sample is collected each metre along the length of the trench. Rock samples are collected from in-situ outcrops during reconnaissance work.

Trench and rock samples were sent to the ITS (PNG) Ltd (Intertek) Laboratory in Port Moresby. Gold assays were conducted using 30 g charge Fire Assay with Atomic Absorption Spectra finish (Intertek Code FA25/OES), with a detection limit of 0.01ppm. Samples >1 ppm (1 g/t) Au were re-assayed as a check with no significant difference noted.

Multi-element assays were determined using 4-acid digestion with Induced Coupled Mass-Spectrometry (ICPMS) (Intertek code 4A/MS48). Certified reference material, duplicates and blanks were inserted into the sample stream to monitor laboratory performance, with no significant variations from expected results.

Soil Sampling

Soil sampling involves sieving a c-horizon soil to a <2 mm in the field with the sample secured on site before being staged. Soil samples were sent to the ITS (PNG) Ltd (Intertek) Laboratory in Port Moresby for assay. Assaying for gold and other elements is determined by aqua regia digestion with a mass-spectrometry finish (Intertek code AR01/MS). Certified Reference Material, duplicates and blanks are inserted in the sample stream to monitor laboratory performance.

About South Pacific Metals Corp.

South Pacific Metals Corp ("SPMC") is an emerging gold-copper exploration company operating in the heart of Papua New Guinea's proven gold and copper production corridors. With an expansive 3,000 km² land package and four transformative gold-copper projects contiguous with major producers K92 Mining, PanAust and neighbouring Barrick Gold, 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: Anga, Osena, Kili Teke and May River.

Immediately flanking K92's active drilling and gold producing operations to the northeast and southwest, SPMC's Anga and Osena 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 (TSX.V: SPMC) and Frankfurt Stock Exchange (FSE: 6J00).
