TNG Limited (TNG) proposes to construct and operate the Darwin Processing Facility at Middle Arm, Darwin Harbour, within Lot 1817, Hundred of Ayers. The facility would process magnetite concentrate railed from TNG's (separately proposed) Mt Peake Project, 1400km south of Darwin. The following products would be produced and exported through East Arm Wharf to international customers:
- titanium dioxide – a pigment for use in paint, varnish, paper, plastics, and other materials including inks, fibres, cosmetics and food
- vanadium pentoxide - for use as an alloying agent in steel, catalyst and ingredient in battery manufacture (including vanadium redox batteries)
- iron oxide – the main source of iron for the steel making industry (also known as ferric oxide or hematite)
The project requires assessment at the level of an Environmental Impact Statement under the NT Environmental Assessment Act 1982 with transitional provisions from the Environment Protection Act 2019 and is a 'controlled action' under the Environment Protection and Biodiversity Conservation Act 1999. The relevant controlling provisions are:
- Listed threatened species and communities (sections 18 and 18A) and
- Listed migratory species (sections 20 and 20A).
