Historical Drill Highlights Include:
19 m @11.47% Cu, 2.17g/t Au from 13 m Depth at Ufuo Massive Sulfide Prospect
109 m at 1.53 g/t Au from Surface at Skygate Cu-Au Porphyry Prospect
Vancouver, British Columbia--(Newsfile Corp. - October 30, 2024) - South Pacific Metals Corp. (TSXV: SPMC) (OTCQB: SPMEF) (FSE: 6J00) ("SPMC" or the "Company") is pleased to announce that two significant mineralized districts - the Skygate Cu-Au Porphyry-Epithermal District and the Ufuo Polymetallic Massive Sulfide District - have been identified by the Company following a thorough evaluation data from decades of historical work.
Project Highlights:
- Ufuo Polymetallic Massive Sulfide District: hosts a complex of five massive sulfide bodies, hosted in volcanics with a clear structural control. Two have been drilled with historical results returning high-grade Cu (+Au, Zn, Pb, Ag) near surface: 19 m @11.47% Cu, 2.17g/t Au from 13 m depth1 and 11 m @ 10.07% Cu, 2.03g/t Au from 13 m depth1. Multiple other undrilled geophysical targets remain in this prospect area;
- Skygate Cu-Au Trend: a 7-km long gold-copper mineralized trend lying 15 km west of the giant Frieda River Cu-Au deposit, which hosts 12 Mt Cu and 20 Moz Au2. This trend features confirmed Cu-Au porphyry exposures and historically drilled gold-bearing diatreme breccias. New, advanced review, reprocessing and modeling of historic data has illustrated the potential for sub-surface porphyry targets. This trend lies within similar host rocks and structural setting to that of Frieda River.
- Historical drilling intercepts include 109 m at 1.53 g/t Au from surface1 and 54 m at 1.83 g/t Au from 106 m depth1, with holes ending in +1 g/t Au mineralization; and
- Historical drilling intercepts include 109 m at 1.53 g/t Au from surface1 and 54 m at 1.83 g/t Au from 106 m depth1, with holes ending in +1 g/t Au mineralization; and
- Expansive Copper-Gold Exploration Package: district-scale tenement package (~1,700 km²) , hosting multiple styles of mineralization with more than 20 identified prospects ranging from high grade polymetallic massive sulfide, epithermal Au and porphyry Cu-Au-Mo1.
As a result, the Company is currently evaluating various non-dilutive, project-level financing options to advance exploration efforts which may include surface sampling, mapping and drilling. Refer to Figure 1 for an overview of prospects at May River.
"As we continue to evaluate and integrate over 25 years of exploration data with regional known geology, our efforts to delineate May River's full mineralized potential continue to expand," stated Cathy Fitzgerald, President and Chief Geologist. "Our recent 3D advanced geological and geophysical modeling, combined with prior surface sampling and drill results, have already defined high-priority targets at Skygate and Ufuo for drilling. This district-scale approach to early-stage deposit evaluation underscores the prolific nature of May River's land package and further growth opportunities with multiple additional anomalies warranting follow-up. Our near-term goal is to advance our existing drilled prospects and test the remaining tenement package to qualify additional targets."

Two Significant Mineralized Districts Prioritized
Ufuo Polymetallic Massive Sulfide District: in the northern region of the May River tenement package lies the Ufuo District, which hosts a cluster of five massive sulfide bodies occurring over a 3 km by 5 km area within a NW trending mineralized corridor. These were discovered outcropping in 1993 by Highlands Gold, who completed several surface mapping, trenching and drilling campaigns, along with electromagnetic geophysical surveys. Four of the five bodies have been drilled (in 1993, 1997 and 1998), with one lens returning intercepts of 11 m @ 10.07% Cu and 2.03 g/t Au from 13 m1 and 19 m @ 11.47% Cu and 2.17 g/t Au from 13 m1. Both holes have up to 4 % Zn, 3 % Pb and 115 g/t Ag (over 1 m intervals) suggesting a polymetallic system1. A total of 39 holes were completed (3,026 m) at Ufuo. Trenching at one body also returning exceptional results that warrant follow up, including 40 m @ 2.5 g/t Au and 28 m @ 2.5% Cu, 1.1 g/t Au at surface1. Refer to Figure 2 for geology and drill intercept information and Appendix 1 for more drill hole and quality assurance and quality control information.
Historic reporting by Highlands Gold suggested the systems represent Volcanic Hosted Massive Sulfide ("VHMS" or "VMS") style deposits, however they, and several outside researchers also note that there is a) clear structural control on the bodies; b) notable high gold content b) a clear magmatic input into mineralization, i.e., possibly related to a porphyry Cu-Au intrusive. Only 5 km to the NE, outcropping chalcopyrite bearing diorite was mapped and it is towards this body that the gold content increases across the prospect area.
The recent comprehensive data review completed by the Company shows that the deposit model applicable to these bodies should not be restricted to classifying these as "VMS" deposits. Further, the Company has completed new interpretation of the high-quality historical airborne magnetic data collected in 1990's and 2010's. Advanced 3-D magnetic modelling has identified a prominent target beneath the exposed massive sulfide mineralization at one Ufuo prospect, along with other proximal targets (refer to Figure 3).

Skygate Cu-Au Porphyry-Epithermal Trend: a 7-kilometer-long zone of Cu-Au mineralization, containing both porphyry and epithermal mineralization. It lies within the same geological and structural setting as the Frieda River Cu-Au system, which hosts 20 Moz Au and 29 Blbs Cu (refer to Figure 1)2. At the northern end of the Skygate Cu-Au Trend, there is confirmed Cu-mineralized breccias and stockworks at surface (the Company, under previous management, sampled this Mountain Gate prospect in 2022, see news release dated February 15, 2023). At the southern end, is the Skiraisa Gold Breccia, a historically drilled diatreme breccia hosts high-sulfidation gold mineralization (refer to Figure 4).
Historical drilling at the Skiraisa Gold Breccia has returned exceptional gold intercepts, including 109 m at 1.53 g/t Au from surface1 and 54 meters at 1.83 g/t Au from 106 m depth1. Both holes ended in mineralization above 1 g/t Au and remain open, suggesting a larger Au system, possibly related to a porphyry intrusive, may be present. Drilling was completed by Highlands Gold (1990-1994) and Niuminco (2011). Refer to Appendix 1 for more drill hole information.
The recent comprehensive data review completed by the Company interprets that Skiraisa represents a shallow expression of a mineralized porphyry system, and historic drilling defines a gold mineralized body more than 150 m wide and open to the east and to depth. There are several lines of evidence that a significant porphyry target underlies Skiraisa:
- Historic reports note porphyry-style mineralization (quartz-sulfide (chalcopyrite) was noted in felsic intrusive clasts within the diatreme breccia suggest a deeper Cu mineralized target; and
- Analysis of drilling and surface data, combined with new advanced 3-D magnetic and geological modelling has identified a strong magnetic feature down plunge of the near-surface gold mineralization at Skiraisa (refer to Figure 5).

About the May River Project
The May River Project covers an expansive mineralized district covering almost 1,700 km2 and is located less than 15 km from, and immediately west of, PanAust's giant Frieda River Cu-Au Deposit. The Project hosts two historically drilled Cu-Au mineralized districts, the Ufuo Polymetallic Massive Sulfide District and the Skygate Cu-Au Porphyry-Epithermal Trend. Recent geological and geophysical modeling has identified priority geophysical targets directly beneath these mineralized systems that warrant future drilling. Regional work has also identified more than 20 other prospective areas at May River, representing several deposit styles including polymetallic (VMS), epithermal Au and porphyry Cu-Au. The Project, which was acquired by the Company in April 2023 (see news release dated April 3, 2023) encompasses a large, highly mineralized district in East Sepik Province in Papua New Guinea.
