OceanaGold’s Waihi PEA Outlines Production Growth In New Zealand

The Waihi District preliminary economic assessment (PEA) from OceanaGold suggests an additional 2.2 million oz. of gold output from the Waihi district between 2021 and 2036.

These additional ounces would be sourced from the Marth and Gladstone open pits as well as from the underground portions of the Martha and Wharekirauponga (WKP) deposits.

Based on a growth capital estimate of US$447 million over eight years for the producing site and life-of-mine all-in sustaining costs at US$627 per oz., the after-tax net present value estimate for this additional development comes in at US$665 million, at a 5% discount rate.
