Other alloying metals
Significant vanadium and titanium resources occur in the Arunta Region in central Australia, associated with vanadium-rich magnetite hosted in mafic intrusions.
The largest of these is the Mount Peake vanadium-titanium-iron deposit near Barrow Creek. It has a resource of 160 million tonnes, and was the subject of a definitive feasibility study in 2015 for a proposed mine to produce high purity vanadium pentoxide, pig iron and titanium dioxide.
Tungsten and molybdenum
The Northern Territory (NT) has several tungsten and molybdenum fields. The largest of these in terms of historical production are the Wauchope and Hatches Creek tungsten fields located in the Davenport Province, which produced 4270t of tungsten concentrate.
Skarn-type scheelite-molybdenite mineralisation occurs at the Molyhil deposit in the Arunta Region, which has a resource that includes 13,100 t of contained tungsten and 6,220 t of contained molybdenum.
The NT contains a large number of tin prospects and occurrences, with past production of around 10,000 t of tin concentrate. Mineralisation is most commonly associated with quartz veins, particularly in the Pine Creek Orogen, although it is also locally occurs associated with tantalum within pegmatite bodies.
Tin- and tantalum-bearing pegmatites in the Bynoe area are located in a north-trending, 10 km-wide belt and have total recorded production of 533 t of cassiterite concentrate and 63 t of tantalite concentrate. Tin-tantalum pegmatites are also present in the Arunta Region, particularly near Barrow Creek.
The tin-tantalum bearing pegmatites in the Bynoe area and Arunta Region also have significant potential to host lithium.
The Territory is largely underexplored in relation to nickel.
The only defined resource is 59,550 t of nickel included as part of the polymetallic Browns resource in the Rum Jungle mineral field in the Pine Creek Orogen.
However, there is considerable potential for nickel sulfide deposits in Proterozoic basement rocks in the NT, particularly the Arunta Region where a number of nickel sulfide prospects have been identified and numerous generations of mafic and ultramafic intrusions are considered fertile for nickel mineralisation and remain effectively unexplored.
Feeders to the widespread flood basalts of the Kalkarindji Province in the northern half of the NT are also a prospective exploration target.
