Donald Rare Earth & Mineral Sands Project

Victoria, Australia

The Donald Rare Earth & Mineral Sands Project represents an important new source of global supply at a time of growing demand and challenged supply, with the maturing of established production sources and a lack of new projects coming online. Donald represents a Tier One deposit in terms of scale, with an expected mine life of at least 58 years and the value of mineral assemblage, notably the rare earth and zircon content.

Project Overview

The Donald Rare Earth and Mineral Sands Project has a total Mineral Resource of 5.8 billion tonnes of ore, at an average heavy mineral (HM) grade of 3.2%. The  Project consists of the Donald and Jackson deposits. Within the Donald deposit area (MIN5532 and RL2002), there are Ore Reserves of 825 million tonnes (Mt) of ore, with an average HM grade of 4.5%. This equates to an approximate, in-situ ore body of 37Mt of heavy minerals, including 6.6Mt of zircon, 10.5Mt of ilmenite, 10.5Mt of higher titanium content products of rutile and leucoxene, as well as a significant rare earth element component of 724kt.

Ore Reserves & Mineral Resources

The Donald Rare Earth and Mineral Sands Project is a globally significant, Tier 1 source of mineral sands, with considerable contents of in-situ titanium dioxide, zircon and rare earth elements.


The Donald Rare Earth & Mineral Sands project is located in regional Victoria and encompasses a total tenement area of 426km2. The area is mainly cleared land used for cropping and grazing and is located close to supporting infrastructure.

The Donald and Jackson deposits are WIM style heavy mineral sands accumulations, amenable to a staged, long life mining operation.

Evaluation & De-Risking

Evaluation & De-Risking

The Donald Rare Earth and Minerals Sands Project has been subject to detailed evaluation over many years, with all main regulatory approvals completed or well advanced.

Mining, Concentrating, Mineral Separation & Rehabilitation

Mineral sands mining involves four main stages: mining, wet concentration, mineral separation and rehabilitation. Mining can be performed either by dry mining methods (employing scrapers, dozers and excavators, typical for dunal deposits) or a wet mining process (employing floating dredges, typical for large unconsolidated deposits).
