Magnesium is one of the world‘s most important industrial metals. Valued for its exceptional strength-to-weight ratio and ability to flex, it plays a critical role in aerospace, defence, automotive manufacturing and advanced engineering. As global demand continues to grow, secure sources of magnesium are becoming increasingly important to international supply chains.
Hardie Pacific’s Southland deposits are located in one of New Zealand’s most promising mineral provinces, supported by a surplus supply of renewable hydro and wind power and proximity to the Port of Bluff. The projects benefit from a fully approved, operational surface quarry and an established industrial workforce supporting 24-hour operations.
Southland’s extensive ultramafic rock formations, covering approximately 665 km², hosts magnesium together with associated nickel, copper and chromium. These projects are well positioned to support the diversification of future magnesium supply.
Hardie Pacific has spent more than a decade evaluating ultramafic systems throughout New Zealand. This work includes geological mapping, exploration, resource evaluation, drilling and metallurgical laboratory research undertaken in collaboration with leading international laboratories and institutions.
As governments and industries prioritise secure and transparent supply chains, new producers with strong geological foundations and strategic alignment are becoming increasingly important. Hardie Pacific’s regional footprint, combined with expert geologists and rising demand from advanced industries, positions its critical mineral assets within a broader global shift toward resilient, future-focused mineral supply.
