South Pacific Metals Announces More Mineralised Structures Discovered at Ontenu NE: Assay Results up to 13.9g/t Au, 388g/t Ag, 0.26% Cu

Executive Summary
- South Pacific Metals reports multiple new mineralized structures at the Ontenu NE prospect, with several high‑grade assays (up to 13.9 g/t Au and 388 g/t Ag).
- The discovery expands the known zone south of earlier September 2025 results, now identifying at least six distinct structures over several hundred metres.
- Drill planning is underway to test these targets in the coming month, indicating imminent advancement from surface sampling to drilling.
Key Details

- Sample E21070: 13.9 g/t Au, 388 g/t Ag, 218 ppm Cu (0.5 m wide breccia with smoky quartz veins).
- Sample E21056: 3.68 g/t Au, 302 g/t Ag, 320 ppm Cu (30‑50 cm vein).
-
Sample E21067: 3.36 g/t Au, 15 g/t Ag, 169 ppm Cu (oxidised breccia).
-
Additional Samples – Eleven other samples returned 0.1–1 g/t Au with up to 184 g/t Ag and 0.26 % Cu.

Comparison to Prior Results (Sept 17 2025)
-
Previously reported assays: 3.95 g/t Au, 1.2 % Cu, 603 g/t Ag; 2.65 g/t Au, 0.6 % Cu, 337 g/t Ag; 2.18 g/t Au, 0.1 % Cu, 100 g/t Ag.

Geological Context
- Ontenu NE lies within the Kainantu Transfer Zone, a major NE‑SW corridor hosting the high‑grade Kainantu Gold‑Copper mine (K92 Mining).
-
Multiple epithermal Au‑Cu targets identified: ≥6 mineralized structures mapped over several hundred metres; soil anomalies up to 1.2 km long.
-
Future Work
- Ongoing mapping, trenching, and reconnaissance across Ontenu and the broader Osena Project.
-
Drill program being finalized; first holes expected in the coming month.

Qualified Person – Dr. Darren Holden (BSc(Hons), PhD, FAusIMM) reviewed and approved technical information per NI 43‑101.
Notable Quotes
“We are pleased by the continuing discovery of more of these mineralised structures. We believe these structures could represent the upper levels of deeper, higher grade epithermal Au‑Cu veins.” – Timo Jauristo, CEO, South Pacific Metals Corp.
“Our drill planning is well underway and we are geared up to start drill testing these targets in the coming month. We are excited to start drilling the first holes to test these targets.” – Timo Jauristo, CEO.
