Tiwi Islands, Northern Territory

The Tiwi Islands (consisting of the Melville and Bathurst Islands) are located approximately 50kms north of Darwin, a 25-minute air flight from the mainland. 

MZI Resources, under the previous owner Matilda Minerals, has been present on the Tiwi Islands since 2006 Mineral sand from the Tiwi deposits is high in zircon and rutile.  Typically, the concentrate produced has a zircon content of 40% – 50% and rutile at 40%.

MZI’s first operation on the Tiwi Islands commenced in 2009 at Lethbridge West, located on Melville Island. It was a small deposit producing 11,500 tonnes of concentrate from 134,500 tonnes of mined ore over a 4-month period. Mining ceased in 2010 and the site has been rehabilitated back to its pre-mined condition.

In 2010, MZI commenced the Lethbridge South deposit on Melville Island, located 4kms south east of Lethbridge West.  It was four times the size of Lethbridge West and half the grade at 2.5% heavy mineral. The final shipment from Lethbridge South was made on the 16th January 2013. Rehabilitation of the mine site is well advanced.


Through its previous operations on the Tiwi islands, MZI has developed strong relationships with the Northern Territory Government and local communities on the Tiwi islands.
