OceanaGold Corporation announced results from seven drill holes from the ongoing exploration and resource conversion program at Wharekirauponga, located approximately 10 kilometres ("km") to the north of the Company's Waihi operation in New Zealand. Drilling Highlights (estimated true width): 4.0 m @ 43.8 g/t Au from 467.5 m, EG vein (WKP137); 8.1 m @ 11.8 g/t gold from 646.4 m, EG FW vein (WKP137); 5.9 m @ 14.7 g/t Au from 398.6 m, EG HWS vein (WKP137). 4.1 m @ 11.5 g/t Au from 532.4 m, EG vein (W KP137); 6.1 m @ 5.6 g/t Au from 446.9 m, EG vein (WKP138).
Gold mineralization continues to increase in scale and is now defined over a strike length of more than 1.4 km, including a further 240 metres to the south of previously intercepted mineralization, and remains open in all directions. Results for seven of these holes have been received and continue to demonstrate the significant potential to expand the mineral resource associated with the EG vein zone. Drilling completed includes two exploration step-out holes from the most southern drill site, drill site 9, one resource conversion hole from drill site 8 and five resource extension holes from drill sites 1, 8 and 9 (Figure 1).
Two widely spaced exploration step-out holes, WKP138 (6.1 m @ 5. 6.9 m @ 0.5 g/t Au), have now extended mineralization a further 240 metres south of the current Inferred Resource and previously intercepted mineralization (WKP135 6.3 m @ 8.7 g/t Au, released March 2025). The EG vein zone remains the primary, near-term target for drilling in 2025 with approximately 5,000 metres remaining to be drilled this year. Quality of exploration assay results has been monitored in the following areas: Sample preparation at the SGS Waihi and Westport labs through sieving of jaw crush and pulp products; Monitoring of accuracy of the primary SGS assay and ALS results through insertion Certified Reference Materials ("CRMs") and blanks into sample batches.
Failure in any of these holes are expected to be completed by the SGS assay results are expected to be completed in 2020.
