Development of the A21 pipe remains on schedule. The company is maintaining the same diamond production guidance in 2017, that of 19 to 24 million carats.
Speaking on the company’s overall production results, Rio Tinto chief executive J-S Jacques said “Despite challenging weather conditions at our West Australian and Queensland operations, we delivered solid production in the first quarter of 2017. Our strategy is unchanged. Our number one priority is safety. We maintain our disciplined approach to capital management and maximising cash flow, with a focus on managing costs and enhancing productivity across the business. These actions support the delivery of strong cash returns to shareholders in the short, medium and long term.”
