In 2015, production of diamonds Rio Tinto Diamonds has increased by 25% compared to the same period last year, to 13.87 million carats to 17.40 million carats. This is due to the increase in production at the underground part of the mine Argyle (Argyle), which outweighed the decrease in diamond production at the Diavik Project (Diavik). Reduced production at Diavik was due to the temporary suspension of the processing plant in the fourth quarter due to the lack of sufficient quantities of ore for processing. Its main was processed in the first half of 2014.
However, Rio Tinto profit in 2015 fell 30% to $ 189 million, versus $ 269 million in 2014. Although the gross profit in 2014 was $ 901 million in 2015, Rio Tinto has registered a decrease of this indicator to $ 698 million. In 2015, net income was $ 79 million versus $ 104 million in 2014.
The company's profit decline was due to the decline in most categories of diamond prices, but also due to lower sales volume due to the weakening markets. The reasons for the negative results could be a decline in demand in India and China, higher prices for diamonds and a high volume of diamonds ready for sale.
In June 2015 Rio Tinto completed the sale of its stake in the diamond mine Murowa (Murowa) in Zimbabwe, but did not make any acquisitions in 2015.
Tube A21 Development on the project Diavik in Canada, owned by Rio Tinto to 60% will ensure the preservation of the current levels of production. It is expected that this area will be mined diamonds at the end of 2018, the company added.
Group continued to improve its strategy for exploration expenses on the basis of revenue received in 2014, and focused on the development of high-priority projects.
In 2015, approximately 23% of the costs of exploration Rio Tinto had on a division of diamonds and minerals (Diamonds & Minerals).
