Through the careful and innovative design of our exploration activities, we reduce our footprint, minimise the impact on habitat and remediate using best-practice environmental management.

North Island

Wharekirauponga (WKP)

OceanaGold commenced exploration of the WKP prospect in August 2017. By the end of 2019, we had drilled approximately 26,995 metres and declared an initial indicated resource of 0.41Mt at 18.0g/t Au for 296,000 ounces of gold, and an inferred resource of 1.05Mt at 11.9g/t Au for 401,000 ounces of gold.

While it is still early in the exploration process, WKP presents an exciting target where drilling is ongoing. We are taking great care to manage our exploration activities in the Coromandel, so habitat disruption is kept to a minimum. We do not enter the area without authority from the landowner and the Department of Conservation (DOC), the necessary consents from regional and district councils, and must continually report on our activities and results. An Access Arrangement with DOC sets out our operating requirements, including; approval of an Annual Work Program pursuant to an authority to enter and operate, a Kauri Dieback Management Plan, a Wildlife Act Authority and extensive detailed flora and fauna surveys by qualified ecologists.

Independent experts have conducted and continue to conduct baseline ecological surveys to map all areas we identify as potential drill sites. These ecological surveys specifically search for threatened or at-risk native flora and fauna species, in order to avoid impacting upon them, or their environment, including; Archey’s and Hochstetter’s Frogs, Coromandel Striped Gecko’s, Paua Slugs, Bats and King Ferns.

Our exploration activities are helicopter-supported and utilise raised platforms with a small footprint to store all equipment, minimising surface disruption and further protects flora and fauna.

We actively support efforts to limit the spread of Kauri Dieback. Kauri Dieback is a pathogen spread through soil particles and is threatening Kauri Trees. We are committed to ensuring our mining activities do not contribute to the spread of Kauri Dieback, by thoroughly cleaning and disinfecting any footwear and other equipment (including our helicopters and drilling equipment) upon entry, exit or passage between sites in the area.

South Island


Along the Hyde-Macraes Shear Zone (HMSZ), the host structure to over 5Moz mined to date at Macraes, we have conducted detailed geological mapping, geophysical surveys (including seismic surveys, magnetic and electromagnetic surveys), geochemical surveys (including stream sediment sampling, soil sampling and trenching), remote sensing and aerial photography.

Target areas with favourable characteristics for gold mineralisation have been systematically tested, with approximately one million metres drilled to date.

Current exploration is aimed at a combination of infill and extensional drilling adjacent to the operational mining area and drill testing satellite targets along strike to the NW and SE along the HMSZ.

With a significant resource defined at the Round Hill Project, exploration is focused on growing this resource base and identifying higher grade zones, following encouraging drill results at the Golden Point target.

Discovery and resource expansion through exploration has led to the production of over five million ounces of gold (as of March 1, 2017).
