The story

OceanaGold was founded in 1989 in New Zealand, then known as the Macraes Mining Company Ltd. The company commenced gold production at Macraes in 1990. The company became GRD Macraes Ltd in 1998 through a takeover of Macraes by Perth-based GRD, with business journalist Brian Gaynor describing the merger as "one of the worst cases of company looting since the 1980s". GRD had been under financial pressure in 1998 and the takeover gave it access to the cashflow of the New Zealand company.

In December 2003, the Perth-based parent company launched a share issue for a new New Zealand-based company to be called Oceana Gold, with the aim of raising NZ$114 million and half the income going to GRD Macraes in exchange for the New Zealand assets. Oceana Gold listed on both the Australian and New Zealand stock exchanges in mid-March 2004. GRD Macraes sold its remaining shareholding in OceanaGold during 2006.

Products and brands

New Zealand

The Macraes Operation, located on the South Island of New Zealand, is the country’s largest gold producing operation. The wholly owned Macraes Operation includes the Coronation, Coronation North, Innes Mills, Deepdell North, Deepdell South, Golden Point, Northwest Pit, Round Hill, Southern Pits, Innes Mills, Innes Mills West, Gay Tan and Frasers open pits, Frasers and Golden Point underground mines, and an adjacent processing plant including a pressure oxidation plant for the processing of sulphide ore. The Macraes Operation has been mining and processing gold bearing ore since 1990 and has produced over 5 million ounces. In November 2025, The Otago Regional Council extended the company's Macraeas gold mining consent for another five years.

The Waihi Operation is located on the North Island of New Zealand and was acquired by OceanaGold from Newmont Mining Corporation (Newmont) in 2015. The mine comprises two areas of mineralisation which are at different stages of development, being underground and open pit mining. It consists of two mining operations in Waihi and the Martha underground mine. On 18 December, Oceana Gold's proposed Waihi North extension became the first mining project to gain approval under the New Zealand Government's Fast-track Approvals Act 2024's regime.

Philippines

In 2006, OceanaGold acquired the Didipio Gold-Copper Project in the Philippines through a merger with Climax Mining Limited. Didipio is in the north of Luzon Island, approximately 270 kilometres northeast of the capital Manila. The Financial and Technical Assistance Agreement (FTAA) currently covers approximately 8.621.38 km2 (as confirmed by the MGB in their letter dated 7 September 2022) located in the provinces of Nueva Vizcaya and Quirino. The nearest significant towns to the Didipio Mine are Cabarroguis, located approximately 20 kilometres to the north, and Kasibu to the west. The main road access to Didipio is via a concrete sealed road to Dibibi in Cabarroguis, and from Dibibi there is a 22-kilometre all-weather concrete-gravel road to the mine site. A secondary access connects Didipio by an all-weather gravel road to Kasibu, which is in turn connected by concrete road to the Pan-Philippine Highway at Bambang, Nueva Vizcaya.

In March 2023, OceanaGold announced that it will invest up to $50,000,000 to boost outputs and expand its operations in Nueva Vizcaya.

Lancaster County lies in the north-central part of the state. The Haile property site is approximately 17 miles southeast of the city of Lancaster, the county seat, which is approximately 30 miles south of Charlotte, North Carolina.
