BHP Announces $840 Million Investment Expanding Olympic Dam Copper Operations

BHP is investing over A$840 million to expand its Olympic Dam copper, gold, and uranium mine in South Australia, aiming to significantly increase copper production from 1.7 million tonnes to around 2.5 million tonnes annually. The investment funds key projects including a new underground access tunnel to the Southern Mine Area, a backfill system to stabilize mined sections, an extension of the underground electric rail network with six new trains, and a new oxygen plant to boost smelter performance. These upgrades are expected to create around 200 to 250 construction jobs and improve operational efficiency, reinforcing South Australia's position as a globally significant copper supplier. The expansion aligns with growing global demand for copper driven by renewable energy and electric vehicles, positioning BHP and Australia to meet critical mineral needs essential for low-carbon economies. Despite some concerns about high energy costs influencing future investments, BHP remains committed to the Olympic Dam project and its strategic growth in the region. This investment also supports ongoing projects across BHP's South Australian operations, including accommodation expansions for workers ahead of future smelter maintenance.
