On July 7, BHP Group declined 3.02% overnight, trading at approximately $81.11/share, with turnover of $1.1127 million. The sell-off was triggered by the approval of early-stage works for the Escondida copper mine expansion in Chile, which raised market concerns over escalating capital commitments.

BHP confirmed that Chile's Antofagasta Environmental Assessment Commission approved early-stage works involving sulfide leaching and electricity upgrades, costing approximately $1.3 billion. The company plans to invest between $10.7 billion and $14.7 billion in its Chilean operations over the coming years, including a $1.5 billion application to reopen the Cerro Colorado mine and a $5.9 billion new concentrator plant. BHP holds a 57.5% stake in Escondida, with Rio Tinto holding 30%.

Market concerns intensified as BHP had recently recorded a $2.3 billion impairment charge on its Jansen Stage 2 potash project in Canada after costs escalated from $4.9 billion to $6.9 billion. The broader diversified metals and mining sector traded lower, with Rio Tinto falling 1.69% and Teck Resources declining 1.38%.
