South Pacific Metals Corp.: South Pacific Identifies New Mineralized Zones at Golkona South, Anga Project

Vancouver, British Columbia--(Newsfile Corp. - October 14, 2025) - South Pacific Metals Corp. (TSXV: SPMC) (OTCQB: SPMEF) (FSE: 6J00) ("SPMC" or the "Company is pleased to announce the discovery of a new gold-copper mineralized zones at Golkona South, part of the Company's Anga Project in Papua New Guinea. The Anga Project lies immediately northeast of, and contiguous with, K92 Mining's tenements in the Kainantu District - a highly prospective gold-copper district in PNG.

Highlights - Golkona South:

• 2.2 × 1.1 km gold in soil anomaly identified, with high soil assays (peak value 1080 ppb Au) the highest soil gold values reported on the Anga project to date.

• Two zones of high copper (over 1000pm Cu) and silver (over 250 ppb Ag) in soil samples with peak results up to 3,397 ppm Cu and 2160 ppb Ag - within the broader gold in soil anomaly mentioned above.

• Panned concentrate samples from streams draining Golkona South contain up to 282 ppm Au, indicating a local source.

• The anomalous area is coincident with mobile MT conductivity features, which correlate with known deposits in the Kainantu region.

• Regional interpretation reveals a northeasterly trend to the geophysical and structural features, with K92's Arakompa deposit along that trend to the southwest.

Next Steps:

• Geochemical sampling will continue at Golkona South, the adjacent Golkona prospect and the broader Anga tenement. Geological reconnaissance and mapping at Golkona South and Golkona prospect will help to understand the nature of the mineralisation and its prospectivity.

• This information, together with past geochemistry and geophysics, will be used to help define initial drill targets.

"We are very pleased with these latest soil geochemical results at Golkona South," said Timo Jauristo, CEO of South Pacific Metals Corp. "The potential of Golkona South and the Anga tenements are highlighted by these results and their location along the northeasterly trend from K92's large and growing Arakompa project. We look forward to continuing to advance this project, although our immediate priority is the imminent start of drilling to test the exciting epithermal vein targets at Ontenu NE."

About South Pacific Metals Corp.

South Pacific Metals Corp. 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 3,100 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: Anga, Osena, Kili Teke, and May River.

Immediately flanking K92 Mining'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 Mining'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).

Quality Assurance and Quality Control

Soil Sampling
Soil sampling involves augur or dig to the c-horizon and sieving to a <2 mm in the field. Soil samples were sent to the ITS (PNG) Ltd (Intertek) Laboratory in Lae for assay. Assaying for gold was conducted for gold using FA50, with pulps sent to Australia for aqua regia AR10 multi-element techniques. Certified Reference Material (CRM), duplicates and blanks are inserted in the soil sample to monitor laboratory performance, with no significant variations from expected results. Refer Table 1 in appendix for full results.

Stream sediment / pan concentrate
Pan concentrate soil samples are collected from stream sediment trap sites above the confluence of individual streams. A field technician places approximately 2 to 4kg of wet sediment into a gold pan, and pans to concentrate between 50g and 100g of heavy minerals, which typically include magnetite and other iron oxides, sulphides and native metals including gold. By its nature, this form of sampling concentrates gold and can provide information to potential gold sources upstream. The Company considers >10ppm Au as indicative of a potential source and >100ppm Au as very encouraging. Further work is required, conducting reconnaissance in the stream catchment, to identify the source. Samples presented in this release were assayed at ITS (PNG) Ltd (Intertek) Laboratory in Lae, using fire assay / 50g charge (FA50). No CRMs were inserted, though the laboratory conducted its own standard checks. Refer Table 2 in appendix for full results.
