Mine Life7 years (as of Jan 1, 2021)
On June 24, 2021, NT Bullion shipped its first batch of iron ore from the Frances Creek mine in six years.

Iron ore mining began at Frances Creek Mine in 1967 and ended after Cyclone Tracy struck in 1974. Iron ore mining recommenced at Frances Creek Mine in 2007. Iron ore production peaked at 2.7 million tonnes in 2013-14, but all operations moved into care and maintenance in 2014 following the collapse in the iron ore price.

Summary:

The Frances Creek tenement group provides a cross section of the Early Proterozoic sedimentary stratigraphy of the Pine Creek Geosyncline. The eastern most tenements cover sedimentary rocks of the Namoona and Mt Partridge Groups; the central tenements cover sedimentary rocks of the South Alligator and Mt Partridge Groups, including the ironprospective Lower Wildman Siltstone, whilst the western tenements cover sediments of the Finnis River and South Alligator Groups. The sediments are complexly folded in a NNW trend. Conformable sills of Early Proterozoic Zamu dolerite are folded with the sediments. Cretaceous quartz-pebble conglomeritic sandstone forms remnant plateaus over the central tenement area.

The South Alligator Group covers the western tenements, hosting the iron-rich Koolpin Formation. The Koolpin Formation is represented by a series of narrow mineralized brecciated siltstone units located in a north-south trending valley located about 2km due west of the present mine workings at Frances Creek. The mineralisation is primarily iron with secondary manganese. The mineralisation can be recognized in the majority of outcrops by a conspicuous dark knobbly siltstone breccia. Occasionally, the iron is a replacement mineral in non-brecciated siltstone. Outcrops containing the manganese mineralisation are less continuous and are more likely to be displaced by faulting.

The Koolpin Formation unconformably overlies the Wildman Siltstone and is conformably ........
