Zug, 26 July 2011
Highlights:
- Stronger second quarter volumes of thermal coal, copper, platinum, nickel and zinc, following weather-related and other operational issues which impacted first quarter production
- A rapid recovery at flood-affected mines in Queensland and volumes from newly commissioned Goedgevonden and Mangoola operations contributed to a 5% rise in thermal coal production to 32.4 million tonnes, despite operational challenges at Blakefield South and Ulan mines
- Mined nickel rose by 31% to 36,709 tonnes, benefiting from the successful commissioning of the Nickel Rim South and Fraser mines and the rapid ramp-up of the Falcondo ferronickel operation
- Mined zinc in concentrate volumes rose by 3% from the Mount Isa Mines and McArthur River operations, despite the impact of flooding in the first quarter, while overall zinc volumes were impacted by planned lower zinc production at Antamina
- A 6% improvement in second quarter mined copper production compared to the first quarter offset the impact of adverse weather in Australia, Chile and Peru on first half production
- The greenfield, 10.5 million ROM tonnes per annum AUD1.1 billion ($1 billion) Mangoola thermal coal mine in New South Wales, Australia successfully commenced operations in February, ahead of schedule and under budget
- In June, the first shipment of iron ore concentrate left Xstrata Copper’s newly commissioned magnetite plant, part of the AUD589 million ($542 million) transformation of Ernest Henry into a major underground copper-gold operation
- Significant increases in mineral resource estimates were announced at the Antamina copper and zinc mine in Peru and the Frieda River copper project in Papua New Guinea

Xstrata Alloys
Ferrochrome production volumes fell by 4% in the first half of 2011 compared to the first six months of 2010, due to a number of furnace refurbishments that were brought forward into the first half. Maintenance activities focussed largely on the more efficient Premus furnaces, resulting in lower consumption efficiencies and increased production costs.
The ferrochrome benchmark price rose from $1.25 per pound in the first quarter to $1.35 per pound in the second quarter, falling by 11% in the third quarter to $1.20 per pound due to weak demand and destocking in Europe and lower demand in China.
Ferrovanadium production volumes decreased by 10% compared to the first six months of 2010, due to a planned two week maintenance shutdown. Some vanadium pentoxide for ferrovanadium conversion was redirected towards direct vanadium pentoxide sales to benefit from more favourable market conditions.
Permitting delays and blasting restrictions for the current open pit operation at Eland resulted in lower PGM volumes in the first half of 2011. Mining recommenced in the second quarter, although the disruption to the mining plan has resulted in a delayed production build-up at the eastern pit. The Mototolo joint venture maintained nameplate ROM production of around 200,000 tonnes per month throughout the period.
The development of both decline shafts at the Eland underground development is progressing well with a total of 7,650 metres developed to date and the bulk of the surface infrastructure completed. Initial production from the first operating level of the western decline, the Kukama shaft, is expected during the fourth quarter of 2011, following the completion of the first phase of the underground ore handling conveyor belt infrastructure.

Xstrata Coal
Australian thermal coal production increased by 9% compared to the first half of 2010, bolstered by the commencement of operations at Mangoola open cut mine ahead of schedule in February. The full impact of new volumes was partly offset by severe flooding in Queensland earlier in the year and, in New South Wales, by the temporary cessation of operations at the Blakefield South mine following an underground fire and temporary interruptions to the Ulan longwall as a result of significant water in the underground operating area.
Despite a rapid recovery at the majority of Xstrata’s mines from the Queensland floods, delays in the repair of damaged rail infrastructure prevented domestic and export sales from the Rolleston operation for several weeks.
Recovery work at the Blakefield South mine is expected to continue through to the end of this year, while production at Ulan is currently ramping up. Semi-soft volumes were lower than the comparable period in 2010, due to the planned closure of the United Colliery in New South Wales in February 2010 and reduced market demand due to the Japan earthquake and tsunami. Planned longwall moves at the Oaky No. 1 and North mines in Queensland and at the Tahmoor mine in New South Wales during the period impacted coking coal production, which was 0.7 million tonnes lower than the same period last year.
South African thermal coal production was slightly higher than the corresponding period in 2010, as the ramping up of Goedgevonden offset the impacts to production of the ongoing transition of the South African coal operations into three large-scale, lower cost, primarily open cut complexes as well as aligning production to available export rail capacity.
Cerrejón volumes were slightly lower than the corresponding period in 2010 due to excessive rainfall during the period.

Xstrata Copper
Total mined copper production in the first half of 2011 was in line with the corresponding period in 2010, with a 6% uplift in the second quarter of 2011 compensating for some difficult operating conditions experienced early in the year. Volumes from Ernest Henry in Australia were significantly higher compared to the first half of 2010 as mining progressed in the final high grade ore zone of the open pit. Production also improved at Lomas Bayas due to higher recoveries and increased throughput as result of improved equipment availability compared to the previous year. This was offset by lower production at Alumbrera compared with last year as a result of a geotechnical event in the fourth quarter of 2010 which temporarily restricted access to high grade zones of the pit and impacted head grades. First half production was also affected by planned lower copper grades and reduced mill throughput at Collahuasi due to adjustments in the mine plan as a result of heavy rainfall in the first quarter of 2011.
Total mined and third party cathode production decreased by 16% due to the closure of the Kidd Metallurgical plant as part of the rationalisation of the Canadian metallurgical complex in May 2010 and a temporary plant shutdown at the Townsville refinery in the first quarter of 2011, due to a severe tropical cyclone in north Queensland in February.

Xstrata Nickel
Total nickel production in the first half of 2011 increased significantly to 51,436 tonnes, 13% higher than the same period last year, due to the contribution from the recently commissioned Nickel Rim South and Fraser mines in Sudbury, Canada and the restart in October 2010 of the Falcondo ferronickel operation in the Dominican Republic.
Falcondo has successfully ramped up to a planned annualised run-rate of 14,000 tonnes of nickel in ferronickel per year, 50% of its installed capacity, producing 5,912 tonnes of nickel in ferronickel in the first half of 2011, with improved ore mining management process and increased recoveries.
Total ore mined at the Integrated Nickel Operations (INO) increased by 20% as a result of strong volumes from the Nickel Rim South and Fraser mines in Sudbury and Xstrata Nickel Australasia (XNA). This was partially offset by an overall decrease in head grade, primarily at Raglan due to a move to new ore zones, and at XNA where mining activity is transitioning to lower grade, disseminated ore. As a result, nickel in concentrate production from INO increased by 10% to 30,797 tonnes.
Nickel in matte production from the Sudbury smelter fell 6% in the first half of 2011 due to the deferral of a one-week maintenance shutdown from December 2010 to January 2011. Refined nickel production from the Nikkelverk refinery was slightly higher, producing 45,524 tonnes of nickel metal in the first half of 2011 as a result of successful debottlenecking and process improvements initiated in 2009.
Total mined copper production increased sharply by 46% to 26,673 tonnes compared to the same period last year due to the contribution of the polymetallic Nickel Rim South mine and improved ore volumes from the Fraser mine.

Xstrata Zinc
Despite the impact of flooding in the first quarter, a stronger second quarter performance at Mount Isa Mines and McArthur River Mine led to a 3% improvement in zinc in concentrate volumes from the Australian operations compared to the first half of 2010. However, at Antamina, zinc volumes were impacted by the mine plan progressing into a lower zinc grade ore zone, reducing total zinc in concentrate production by 4%.
Volumes increased at the San Juan, Nordenham and CEZinc operations, but were offset by the permanent closure of the Kidd Creek Metallurgical site in May 2010, which led to a 10% reduction in total zinc metal production.
Despite a 16% increase in ore treated at Mount Isa and 5% increase at McArthur River Mine, total lead in concentrate production decreased by 4% compared to the first half of 2010, due to a fall in lead grades at the Brunswick and Mount Isa mines.
