The mine is owned by Robe River Iron Associates (53% Rio Tinto) and operated by Rio Tinto Iron Ore and is one of twelve iron ore mines the company operates in the Pilbara. In the calendar year 2009, the combined Pilbara operations produced 202 million tonnes of iron ore, a 15 percent increase from 2008. The Pilbara operations accounted for almost 13 percent of the world's 2009 iron ore production of 1.59 billion tonnes.
Rio Tinto's iron ore operations in the Pilbara began in 1966. The mine itself began operations in 1994. The mine has an annual production capacity of 7 million tonnes of iron ore, sourced from open-pit operations. The ore is processed on site before being loaded onto rail. At the height of production, the mine produced 35 million tonnes of iron ore annually.
Ore from the mine is then transported to the coast through the Hamersley & Robe River railway, where it is loaded onto ships. Ore from Mesa J, like from the West Angelas, is taken to Cape Lambert by rail to be exported as fines. The fines have a maximum size of 9.5 mm.
The mine is located near the Mesa A mine. The new Mesa A mine is scheduled to replace the Mesa J mine which is nearing the end of its life span. The combined investment of Rio Tinto in the new Mesa A and Brockman 4 mines is A$2.4 billion.
