South Pacific Metals Identifies Multiple New Copper-Gold Targets At The Kili Teke Project

(MENAFN- Newsfile Corp) Vancouver, British Columbia--(Newsfile Corp. - October 1, 2024) - South Pacific Metals Corp. (TSXV: SPMC) (OTCQB: SPMEF) (FSE: 6J00) (" SPMC " or the " Company "), an emerging gold-copper exploration company operating across Papua New Guinea's proven production corridors, is pleased to announce that multiple new Copper-Gold targets have been identified within the Kili Teke Copper-Gold Porphyry Complex. Results from a recently completed targeting exercise using ALS GoldSpot Discoveries Ltd.'s, (" ALS Geoanalytics ") advanced technologies including geochemical analysis, 3D modelling and machine learning, have revealed 10 new exploration targets proximal to Kili Teke's Central Porphyry (" CP ") which currently hosts an Inferred Mineral Resource of 1.81 Moz Au, 802 kt Cu & 40 kt Mo 1 (see January 12, 2023, press release and NI 43-101 published report on SEDAR+).

Targeting Highlights:

• New Porphyry Targets:
  • Identified at depth beneath the current resource;
  • The Ieru Porphyry, now confirmed as a distinct separate system. Previous trenching returned 132 m at 0.5% Cu and 0.6 g/t Au ;
• New Skarn Targets identified adjacent to the current resource with potential to host high-grade Cu-Au, as evidenced by historically drilled skarns that returned 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; and
• "Porgera-Style" Au Targets: this style of mineralization is commonly associated with strong gold-tellurium-arsenic metal associations. Near to the current resource, the Ridge Gold Area ("RGA") demonstrates these associations. Additionally, soil Au values of up to 9.3 g/t Au occur over a broad region (900 m by 300 m) .

As a result, the Company is currently evaluating various non-dilutive, project-level financing options to advance exploration efforts.

"This work has identified several targets that complement the known mineralized zones at Kili Teke," said Cathy Fitzgerald, President and Chief Geologist. "Results show support for not only additional porphyry and skarn mineralization, but alkalic-style gold at the Ridge Gold Area. This latter style of mineralization is associated with a strong Au-Te-As signature as is observed at Porgera. We are very excited about Kili Teke as an exceptional, yet underexplored mineral system with potential for a 'Porgera-like' gold overprint. We know what we're after, and these results show us where to focus."

The Company engaged ALS Geoanalytics to undertake a comprehensive work program using all available geoscience data for the Kili Teke Cu-Au Porphyry Complex to identify new drill targets for potential resource expansion. The Complex not only hosts a current Inferred Mineral Resource of 1.81 Moz Au, 802 kt Cu & 40 kt Mo at the CP, but also shows multiple lines of evidence that other mineralized bodies are present proximal to the resource that remain incompletely tested or have yet to be drilled. There remains significant potential for further discovery at Kili Teke both within the Complex and across the broader tenement.

Advanced Technology Targeting Results

The work has identified 10 new exploration targets proximal to the current resource. Targets were identified using a number of new technologies including LitholensTM, a proprietary technique that leverages artificial intelligence/machine learning and predictive analytics on core photography and downhole geochemistry, in conjunction with the property's vast drilling database (more than 36,000 m), surface geochemical data and geophysical data assembled over many years of exploration by previous operator Harmony Gold (PNG) Exploration Limited, a wholly-owned subsidiary of Harmony Gold Mining Company Limited ("Harmony"). Targets comprise multiple mineralization styles including:

• Porphyry Copper-Gold Targets
  • Results demonstrate that the CP is an upper-level system which vectors towards potential higher grade targets at depth. In addition, this work confirmed that the Ieru Porphyry , located approximately 700 m west of the CP (previous results include trenching which returned 132 m at 0.55% Cu and 0.6 g/t Au ), potentially consists of two N-S elongate targets (potentially porphyry dykes) and is a distinct system with possibly higher tenor gold mineralization than the CP.
• Skarn Cu-Au Targets
  • Results highlight multiple skarn targets, with the potential to host high-grade Cu-Au, immediately peripheral to the CP. Targets are near surface and at depth with potential for high grades indicated by previous skarn intercepts encountered in and around the CMP. Intercepts previously reported include 7.8 m @ 12.98 % Cu, 11.75 g/t Au within 54 m @ 2.1 % Cu, 1.82 g/t Au, 3.87 g/t Ag (from 878 m depth down hole).2
• Porgera-Style Alkalic Gold Targets
  • The Porgera gold deposit is a world-class mineral system located approximately 40 km east of Kili Teke. Porgera is classified as an alkalic style epithermal deposit characterised by high gold grades, large vertical extent and a close association of Au-Te-Bi-As chemistry.

Geochemistry work demonstrated that there are two distinct populations of gold mineralization at Kili Teke: an early Cu-Au-Mo association (porphyry-style), that has been potentially overprinted by later Au-Te-As alkalic related style. The later Au-Te-As mineralization is manifest in association with E-W striking collapse normal faults. Of particular interest is the Ridge Gold Area, a 900 m by 300 m gold in soil anomaly with a very high tenor of Au-Te-As. Previous drilling in this area (two holes) were drilled from the north but did not intersect the main structures of interest. Proximity analysis indicates previous drill results showed alteration indices peripheral to the main target. Alkalic intrusions have been mapped at surface at the RGA but were not intersected by previous drilling.

About the Kili Teke Project

The Kili Teke Project consists of a 253 km2 land package located approximately 40 km west of the Porgera Gold Mine, in the Western Highlands of Papua New Guinea. The Project is 100% owned by the Company and was acquired from Harmony in late 2023. The majority of the exploration work at Harmony was focused on advancing the Central Porphyry to resource stage. This deposit hosts an Inferred Mineral Resource estimate of 235 Mt at 0.34% Cu, 0.24 g/t Au, 168 ppm Mo (1.81 Moz Au, 802 kt Cu & 40 kt Mo)1. Harmony also conducted regional exploration on the wider intrusive complex including mapping, rock chips, soil geochemistry, airborne geophysics (magnetics and radiometrics) and a small amount of trenching and drilling. There remains exciting potential for further Cu-Au porphyry, skarn and epithermal mineralization on the Project.

About South Pacific Metals Corp.

South Pacific Metals 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/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'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.
