Watch for the January 2027 NI 43-101 technical report, which will quantify the impact of these drill results on Mineral Reserves and Resources. The potential processing plant expansion to 1.2 Mtpa and extension of Martha Underground life beyond 2033 are key value drivers. Monitor further drill results from the five active rigs targeting the open southern high-grade zone.

Executive Summary
OceanaGold reported exceptional high-grade drill results from 16 new holes at its Wharekirauponga deposit in New Zealand, including 6.3m @ 97.2 g/t Au, one of the highest-grade intercepts to date. The company also provided a progress update on the Waihi North Project, with decline development advancing 350m since May 2026 and a planned NI 43-101 technical report for January 2027 that may include a processing plant expansion to 1.2 Mtpa. These results support potential conversion of Inferred to Indicated Mineral Resources and an expected increase in Mineral Reserves.
Key Facts
- 16 new drill holes reported from Wharekirauponga, with highlights including 6.3m @ 97.2 g/t Au, 8.5m @ 41.5 g/t Au, and 9.6m @ 18.5 g/t Au
- Drilling confirms continuity and up-dip extension of the southern high-grade zone, which lies outside reported reserves
- Five drill rigs now active at Wharekirauponga; fleet expanded and new drill site (Drill Site 10) constructed
- Waihi North Project decline development advanced ~350m since May 2026; first ventilation shaft construction commenced
- Updated NI 43-101 technical report for the Waihi District planned for January 2027, including updated Mineral Reserves and Resources
- Company evaluating potential processing plant expansion from 0.8 Mtpa to 1.2 Mtpa to support concurrent mining of Martha Underground and Wharekirauponga Underground
- Water treatment plant began staged commissioning in September 2026; early works on new tailings storage facility expected in Q4 2026
Financial Impact
No financial figures provided; the filing is an exploration update with no revenue, earnings, or cost data. The high-grade drill results and project progress suggest potential for increased Mineral Reserves and future production upside.
Risk Factors
- Exploration results are not guarantees of future Mineral Reserves or economic viability
- Waihi North Project development and processing plant expansion subject to permitting, approvals, and execution risks
- Forward-looking statements involve uncertainties including gold price fluctuations, operational risks, and regulatory changes
- Drill hole WKP146D had poor core recovery (~40%), requiring conservative grade estimation
