Ore is natural rock or sediment that contains one or more valuable minerals, typically containing metals, that can be mined, treated and sold at a profit. Ore is extracted from the earth through mining and treated or refined, often via smelting, to extract the valuable metals or minerals. The grade of ore refers to the concentration of the desired material it contains. The value of the metals or minerals a rock contains must be weighed against the cost of extraction to determine whether it is of sufficiently high grade to be worth mining, and is therefore considered an ore.
Limonite is an iron ore consisting of a mixture of hydrated iron(III) oxide-hydroxides in varying composition. The generic formula is frequently written as FeO(OH)·nH2O, although this is not entirely accurate as the ratio of oxide to hydroxide can vary quite widely. Limonite is one of the three principal iron ores, the others being hematite and magnetite, and has been mined for the production of iron since at least 2500 BP.

The Braemar Alliance is a group of ASX-listed public and private mining and exploration companies with projects located in the Braemar region between Peterborough in South Australia and Broken Hill in neighboring New South Wales. The group was formed in 2011 with the intention of devising shared infrastructure solutions to provide water, power and freight corridors for the benefit of all members' projects. The Alliance's member companies have considered using existing outports and developing new ones on the eastern coast of Spencer Gulf to facilitate bulk exports, chiefly of iron ore. These include developing transshipping facilities at Port Pirie and building entirely new facilities at Myponie Point and south of Wallaroo. In July 2011, the Braemar Alliance had determined that its magnetite processing would require 50 gigalitres of water per year and that the water would be provided via a yet-to-be-constructed seawater desalination plant to be located on Spencer Gulf.
