Mining giant Rio Tinto increased its attributable iron-ore production by 9% in the first quarter, but its copper output declined by 18% compared with the first quarter of last year.
CEO Tom Albanese on Tuesday described the three months ended March as a “sold quarter”, in which it also reported higher coal, bauxite, alumina and titanium dioxide production.
“This was driven by a combination of our consistently high operating performance and reduced impact from severe weather than in 2011,” he said.
Rio increased iron-ore production to 59-million tons, of which 46-million tons were attributable. Production was five-million tons above shipments, as ports in Western Australia were closed during the cyclonic activity.
During the quarter under review, iron-ore production and shipping capacity in the Pilbara increased to 230-million tons a year, following the completion of the second debottlenecking project at the Dampier port.
Rio Tinto expects to produce about 250-million tons (on a 100% basis) from its global iron-ore operations in Australia and Canada this year.
The company also said that its expansion plans remained on track, with the its Pilbara operations expected to produce some 283-million tons of iron-ore a year, by the end of 2013.
Liberum Capital described Rio Tinto’s first-quarter iron-ore output as solid, but said copper was a “standout negative”.
During the quarter under review, mined copper production decreased by some 18% owing to anticipated lower grades at the Kennecott Utah copper facility.
Mined copper production declined to 119 500 tons in the quarter, compared with 146 300 tons in the same three-month period in 2011.
Rio said that focus at the Kennecott Utah project has been on mining from the higher-grade molybdenum dome at the bottom of the pit, partly mitigating the effect on molybdenum production.
Lower ore grades are expected to persist through the first half of the year. A 26-day maintenance shutdown at the smelter would occur in the second quarter of 2012 positioning it to take advantage of increasing grades in the second half of the year.
At the Escondida operation, in Chile, milled copper production was consistent with the first quarter of 2011, while mined copper increased by 12% to 68 900 t. Rio said that the 12% increase was owing to an increase in ore delivered to the leaching stockpiles.
Hard coking coal production for the first quarter of the year was 5% higher than the previous corresponding period, to reach 1.7-million tons, while semi-soft coking coal production declined by 12%, to 606 000 t, and thermal coal production increased by 3%, to 4.1-million tons.
Rio noted that wet weather conditions significantly affected production across its Queensland and New South Wales coal operations, with further impacts expected from delays in overburden removal.
First production from Benga mine, in Mozambique, was processed through the wash plant in February with final commissioning nearing completion. The product was expected to be railed to port at the end of April, with the first shipment of hard coking coal from the Beira port expected around the middle of the second quarter.
Meanwihle, the miner also noted that bauxite and alumina production was 10% and 13% higher than the first quarter in 2011, while aluminium production was 9% lower primarily reflecting the orderly shut-down of two-thirds of capacity at the Alma operation, owing to labour disruption and the closure of the Lynemouth operation.
In 2012, Rio Tinto Alcan’s share of bauxite, alumina and aluminium production is expected to be 30.5-million tons, 6.9-million tons and 2.2-million tons, respectively. These numbers excluded the 13 assets that have been identified for divestment or closure. |
