New Zealand Fast-Tracks a Gold-Antimony Mine in the Historic Reefton Goldfield
Rua Gold has filed its full application for the Auld Creek project, an underground mine it says could employ more than 200 people and anchor a wider revival of the West Coast goldfield.
A small Canadian-listed gold explorer has taken its biggest step yet toward becoming a mine developer. Rua Gold said on Thursday it has filed its substantive application under New Zealand's Fast-track Approvals Act for the Auld Creek gold-antimony project, in the Reefton Goldfield on the South Island.
The filing follows the project's acceptance for referral into the fast-track system by New Zealand's Environmental Protection Agency, according to the company. It is now seeking approval for a proposed underground mine and the infrastructure around it through the coordinated consenting pathway, which lets eligible projects pursue approvals under several laws in a single process.
What the project would look like
Auld Creek is planned as an underground gold-antimony operation with an initial mine life of eight years, according to the announcement. The company estimates the project would employ more than 200 people and contribute about NZ$240 million to the regional economy.
Rua Gold presents Auld Creek as the starting point for something larger: a foundation for broader gold and antimony development across the Reefton Goldfield, where it holds more than 120,000 hectares of permits as the dominant landholder. The district has historically produced more than 2 million ounces of gold, according to the company.
The application is backed by technical studies covering water quality, ecology, air quality, traffic, geochemistry, erosion and sediment control, mine closure, and social and economic effects. The company said the proposal was shaped by engagement with Ngāti Waewae, local communities, councils and regulators, and that the conversations will continue as the assessment proceeds.
The road from here
Filing the application is not the same as getting approval. Under the Fast-track Approvals Act 2024, the application first faces a completeness check; if it passes, an independent expert panel is appointed to assess it fully and decide whether approvals are granted, and on what conditions.
Rua Gold said it is targeting receipt of key approvals by mid-2027, while cautioning that the timing depends on acceptance, regulatory review and a favourable decision, and could be affected by requests for more information, suspensions or appeals. In parallel, the company is working on a pre-feasibility study of the proposed mining and processing approach and its economics, targeted for the fourth quarter of 2026. Any decision to build the mine would still depend on those studies, on approvals, on financing and on a final investment decision.
Company executives framed the filing as a milestone in the shift from explorer to developer. Chief executive Robert Eckford said the project could bring gold and antimony production back to Reefton and help address a global shortfall in antimony supply, a metal used in batteries, flame retardants and defence applications. Simon Delander, the company's vice-president for risk, stakeholder and regulatory affairs, said the submission draws together extensive environmental, social and technical work, and thanked Ngāti Waewae and the Reefton and wider West Coast communities for their input.
