Mining giant Rio Tinto Wednesday reported a 93 percent jump in its first-half net profit on the back of rising commodity prices.

The Anglo-Australian firm said net profit was US$3.31 billion in the six months to June 30, compared to US$1.71 billion in the same period last year.

Underlying profit, the measure preferred by Rio, jumped 152 percent to US$3.94 billion.
