Wheelarra is part of BHP's Jimblebar mining hub which has been mined since 1989. Mining at Wheelarra commenced in 2004 with ore transported to Mt Whaleback for processing. Since the Jimblebar processing facility opened in Q3 2013, Wheelarra's ore has been blended and processed at the Jimblebar mine site. Ore from Wheelarra is conveyed 6 km to the Jimblebar processing hub where it undergoes primary and secondary crushing with ore from the Jimblebar mine. Production at Wheelarra has reached its 35 Mtpa capacity and the Wheelarra Joint Venture has expired and wound up. As such, production from Wheelarra and Jimblebar is now reported on a combined basis and our costs will reflect this.
