South Pacific Metals Corp. Completes Anga Gold-Copper Project Field Exploration Program
South Pacific Metals Corp. announced the successful completion of the Irinke Prospect exploration program at its Anga Gold-Copper Project, situated just 4 km northeast along strike of K92 Mining's Arakompa lode-gold vein system and ongoing drilling. Irinke Prospect Exploration Program Results: A comprehensive grid soil and rock outcrop sampling program, along with structural/geological mapping, was completed in August 2024 to better understand the geological and structural setting of previously identified gold mineralization, notably, a high-grade gold-carbonate base-metal vein was sampled that returned 2.28 g/t Au, 9.4 g/t Ag, 418 ppm Pb and 1,254 ppm Zn. Further, the new program aimed to expand the 4 km x 3 km mineralized Au-Cu footprint in soils defined by previous work. This anomalous footprint hosts multiple porphyry and vein-style prospects and suggests that a buried porphyry system is a viable target at Anga. An area of 3.5 km2 was mapped and 169 soil and 68 rock chip samples of outcrop were collected. The Program was successful in identifying and mapping a large North-South striking shear zone, exposed over more than 17 m along strike and 2 m in width. This zone shows similar geological similarities to Arakompa, including similar host rock (diorite) and intense alteration (quartz-sericite-pyrite with chlorite-clay), with sulfides (pyrite and minor chalcopyrite). The Arakompa vein is interpreted to be an intrusive related gold-copper-silver epithermal vein system. Additionally, a 30 cm quartz-carbonate vein breccia that returned 2.28 g/t Au in 2022 sampling has been extended 24 m upstream from the original sample site. Altogether, a total of 169 soil samples and 68 rock chip samples were collected and have been sent to Intertek Laboratory, in Lae, Papua New Guineafor assay. While assay results are pending, all Project data is being evaluated with a better understanding of regional mineralization styles to consider additional regional exploration work programs, including the review of more than 15 porphyry targets identified from historical work in the region by Barrick Gold. Geology and Mineralization at the Anga Project: The western portion of Anga Project is along strike of projections of two significant mineralized gold vein systems, Maniape and Arakompa, located 2 km to 4 km to the SW. These, along with veins currently being mined by K92, have been interpreted to be associated with mineralized porphyry sources. Highly conductive (‘apparent conductivity') airborne geophysical anomalies are spatially associated with these large gold-copper mineralized vein systems. The strong NE trending conductivity anomalies coincident with K92's deposits trend towards the SW corner of Anga, possibly indicating underlying sulphide-rich ore bodies. In this same region at Anga, gold hosted in carbonate base-metal veins have been identified. SPMC had carried out an airborne Mobile Magnetotelluric (Mobile MT) geophysical survey in early 2022, in cooperation with other operators in the area, the results of which show NE-SW striking highly conductive zones of comparable size and orientation to mineralized structures at K92's deposits. Previous surface sampling and mapping work completed in 2021-2022 at Anga (under previous management as Kainantu Resources Ltd.) indicates that the Project hosts similar geology (basement phyllites and diorites intruded by mineralized Miocene porphyries), surface geochemical soil metal signatures (Au-Te-Bi and Cu-Au-Mo-Hg), structurally controlled highly-conductive geophysical anomalies and structural features as that associated with mineralized gold veins and porphyry copper deposits at K92. The Anga Gold-Copper Project comprises 461 km² of 100%-owned exploration licenses in the highly gold-copper mineralized Kainantu Gold District. The project is located immediately northeast of, and adjacent to, K92's Kainantu Gold Mine Project and its southwestern project boundary is only 3 km from where K92 is currently drilling on the Arakompa lode-gold vein system, where wide and multiple high-grade gold zones have been intercepted. Access to the Anga Project is via the Ramu-Markham highway to the northeast. Across the broader 60 km by 40 km sized Kainantu Gold District there are multiple gold and copper occurrences, prospects, and targets. Mineralization is interpreted to be associated with mid to late-Miocene intrusive rock, the NNE oriented Kainantu Transfer Structural Zone and NNW oriented arc-parallel structures, all of which are present at Anga. Since 2020, the Company has been actively engaged with local communities on the Project to ensure consent is gained and maintained to undertake field work programs.
