Rio Tinto Group (NYSE:RIO) shares are trading lower today after the company disclosed second-quarter production results.

The company reported production of 79.5 million tonnes (67.5 million tonnes for Rio Tinto), a decrease of 2% Y/Y, attributed to a mid-May train collision that disrupted rail capacity for about six days and led to full stockpiles at some mines.

Bauxite production increased to 14.7 million tonnes, up 9% from last year, driven by improved utilization and feed rates at Weipa, aligning with the company's full-year guidance to the upper end of 53 to 56 million tonnes.

Outlook: Rio Tinto reiterated outlook for production at Pilbara Iron ore of 323 to 338 million tonnes.

Rio Tinto Chief Executive Jakob Stausholm said: "Our operational performance continues to progress. While there are still significant improvements ahead, we are beginning to see a step-change in production, including from our Queensland bauxite business following the roll-out of the Safe Production System."
