Pilbara iron ore shipments of 69.1 million tonnes (100 per cent basis) in the first quarter were 14 per cent lower than the first quarter of 2018. Production was significantly impacted by the weather disruptions in March and a fire at Cape Lambert A in January. These events will have an impact on second quarter performance.
2019 guidance for Pilbara shipments has been revised to between 333 and 343 million tonnes (previously between 338 and 350 million tonnes, 100 per cent basis). The reduction reflects a slower ramp up and ongoing disruption to shipments caused by weather and other disruptions.
Commissioning of the Amrun bauxite mine was completed in March 2019, with the project delivered under budget and ahead of schedule. Bauxite production of 12.8 million tonnes in the quarter was one per cent higher than the same period of 2018, despite several weather events throughout the quarter significantly impacting production at the Amrun, Weipa and Gove mines.
Aluminium production of 0.8 million tonnes was in line with the first quarter of 2018. Excluding the non-managed Becancour smelter, which was impacted by a lock-out, production was one per cent higher, reflecting continued productivity creep.
First quarter mined copper production of 144 thousand tonnes was three per cent higher than the first quarter of 2018, with strong contributions from Oyu Tolgoi and Rio Tinto Kennecott.
Titanium dioxide slag production of 296 thousand tonnes was one per cent higher than the first quarter of 2018.
First quarter production at Iron Ore Company of Canada was five per cent higher than the corresponding quarter of 2018, despite adverse weather conditions impacting production in February.
At the Oyu Tolgoi Underground Project the review of the mine design and the development schedule is continuing. The commissioning of the main production shaft (Shaft 2) is now expected to complete in October 2019.
