The Mesa A mine, sometimes also referred to as Waramboo mine, is an iron ore mine located in the Pilbara region of Western Australia, 50 kilometres (31 mi) west of Pannawonica.
Contents
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 202,000,000 tonnes (199,000,000 long tons; 223,000,000 short tons) 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 1,590,000,000 tonnes (1.56×109 long tons; 1.75×109 short tons).
The Hamersley Range, where the mine is located, contains 80 percent of all identified iron ore reserves in Australia and is one of the world's major iron ore provinces.
Overview
Rio Tinto iron ore operations in the Pilbara began in 1966. The mine itself began operations in 2010. The mine has an annual production capacity of 25,000,000 tonnes (25,000,000 long tons; 28,000,000 short tons) of iron ore, sourced from open-pit operations. The ore is processed on site before being loaded onto rail.
Ore from the mine is then transported to the coast through the Hamersley & Robe River railway, where it is loaded onto ships.
The mine's workforce is on a fly-in fly-out roster.
The mine is located near the Mesa J mine. The new Mesa A mine is scheduled to replace the Mesa J mine which is nearing the end of its life span. After a two-year construction period and expenses of A$1 billion, the mine began operation in February 2010. The mine is initially scheduled for a mine life of eleven years.

Robe River Iron operates the West Angelas, Mesa A and Mesa J mines. Rio Tinto acquired its share of 53% in late 2000, when it took over mining company North Limitd.
