BHP Group's earnings for the six months to December climbed by more than a fifth, driven by a surge in copper prices that offset weakness in its traditional iron ore business. The mining giant reported the strong profit growth despite plateauing demand in China, which has historically been a major driver of BHP's iron ore and steelmaking coal operations.

While China's slowing demand has weighed on BHP's iron ore and coal segments, the company's strategic pivot toward copper has paid off handsomely. Copper prices have rallied in recent months amid expectations of tight supply and growing demand for the metal in electric vehicles and renewable energy infrastructure. This diversification strategy has helped BHP weather the cyclical downturn in iron ore markets.

The profit beat highlights how BHP's exposure to battery metals is increasingly offsetting traditional commodity volatility. As China's economic growth moderates, the company's copper business has emerged as a critical profit driver, demonstrating the value of BHP's portfolio diversification away from its historical reliance on iron ore exports to Chinese steel mills.
