Analysis · OGC · Energy & Transportation
OceanaGold has formally lodged its Macraes Phase 4 (MP4) permit application under New Zealand's Fast-track Approvals Act, seeking to extend the mine's life from 2032 to the late 2030s. The application covers additional open pit cutbacks, the Southern Pit Innes Mills (SPIM) development, and extensions of the Golden Point Underground. The company expects full permitting by mid-2027, subject to appeals. This is a significant regulatory milestone for a core asset that has produced over 6 million ounces of gold since 1990. The filing also details a record US$13 million exploration program with 60,000 metres of drilling, and drill results that support resource conversion and extension across multiple deposits. While no immediate production or financial impact occurs today, securing MP4 approval is essential to maintaining Macraes' production above 100,000 ounces per year into the late 2030s and potentially into the 2040s via the Round Hill deposit.
