On July 30, BHP Billiton rose 3.01% in pre-market trading, trading at $85.8/share, with turnover of approximately $4.93 million. The movement was driven by sector-wide strength after peer Rio Tinto reported surging earnings on July 29, fueled by robust copper business profits.

Rio Tinto's strong copper-driven results triggered a broad rally across diversified metals and mining stocks. BHP Billiton, as one of the world's largest copper producers, benefited directly from the positive read-through. The company recently secured environmental approval for early-stage works at its Escondida copper mine expansion in Chile, with approximately $14.7 billion in total project investment set to commence. BHP expects to invest between $10.7 billion and $14.7 billion in Chilean operations over the coming years, reinforcing its copper growth trajectory.

Within the Diversified Metals and Mining sector, sector linkage was pronounced. Among individual stocks, Teck Resources rose 6.8%, HudBay Minerals rose 4.64%, Rio Tinto PLC rose 4.0%, USA Rare Earth rose 4.13%, and MP Materials rose 2.76%.
