South Pacific samples up to 13.9 g/t Au at Ontenu
Executive Summary
- South Pacific Metals reports multiple newly discovered mineralized structures at the Ontenu NE prospect, with rock chip assays up to 13.9 g/t Au, 388 g/t Ag, and 0.26 % Cu.
- At least six distinct mineralized structures have been mapped over several hundred metres, accompanied by extensive arsenic‑gold‑copper soil anomalies extending up to 1,200 m.
- Drill planning is underway with field crews prepared to begin drilling the targets in the coming month.

Comparison with Prior Discoveries (Sept 17 2025)
-
Previously reported assays included 3.95 g/t Au, 1.2 % Cu, 603 g/t Ag; 2.65 g/t Au, 0.6 % Cu, 337 g/t Ag; and 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 that hosts the K92 Mining Ltd. Kainantu gold‑copper mine.
-
Multiple epithermal Au‑Cu targets identified: ≥6 mineralized structures mapped over several hundred metres; soil anomalies (As‑Au‑Cu) up to 1,200 m long; structural trends NW‑SE and N‑S consistent with nearby high‑grade veins.
-
Exploration Activities
- Ongoing mapping and rock chip sampling; additional assay results pending.
- Drill program being designed to test the newly identified targets; field crews expected to commence drilling within the next month.
-
Continued trenching and reconnaissance across the broader Ontenu project area and adjacent Anga prospect.

Qualified Person – Dr. Darren Holden (BSc Honours, PhD, FAusIMM), qualified under NI 43‑101, reviewed and approved the technical information.
Notable Quotes
“We are pleased by the continuing discovery of more of these mineralized 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 under way and we are geared up to start drill testing these targets in the coming month.” – Timo Jauristo, CEO, South Pacific Metals Corp.
