CELEBRATING THE COMPLETED EXPANSION OF MINING AND PROCESSING CAPACITY AT BHP BILLITON’S JIMBLEBAR PROJECT THE PILBARA, WESTERN AUSTRALIA TO COMMEMORATE THE SUCCESSFUL JOINT VENTURE WITH SEDGMAN FOR CIVIL; STRUCTURAL, MECHANICAL AND PIPING; AND ELECTRICAL AND COMMISSIONING WORKS AT THE JIMBLEBAR MINE OCTOBER 2016 CIVMEC: THE JIMBLEBAR PROJECT | OCTOBER 2016 1 CIVMEC IS PROUD TO HAVE SUPPORTED BHP BILLITON ON THE JIMBLEBAR PROJECT IN THE PILBARA, WESTERN AUSTRALIA. Congratulations and thank you to everyone involved in the project. The Jimblebar Expansion (JBX) Project The Jimblebar Expansion Project saw the expansion of mining and processing capacity of the existing Jimblebar operations, located in the Pilbara region of Western Australia, four kilometres east of the town of Newman. The mine is fully owned and operated by BHP Billiton, and is one of • Overland Conveyor CV002: 6.2km long conveyor consisting of a • Batch plant for concrete 60m3. seven iron ore mines the company operates in the Pilbara.
