Xstrata: Production Report for the 12 months ended 31 December 2011

Highlights:


- Record annual production from our Australian thermal coal operations following the successful commissioning of the greenfield Mangoola mine on budget and ahead of schedule, the expansion of Newlands Underground thermal coal operation and a strong second half performance;
- Record production of mined nickel, including first ore ahead of schedule from the Kikialik expansion at Raglan mine and record nickel metal volumes from a second successive record year at Nikkelverk;  
- We completed an expansion to extend the life of the Kidd copper mine in Canada on time and within budget and began commissioning the expansion at the Antamina copper-zinc joint venture in Peru at the end of 2011;
- During the second half, we commissioned the 120,000 tonnes per annum Black Star Deeps and 40,000 tonnes per annum Handlebar Hill zinc-lead projects on schedule and on budget;
- Our Falcondo ferronickel operation in the Dominican Republic exceeded expectations to operate at an annual rate of almost 15,000 tonnes per annum, following its restart in February;

We approved seven key projects representing total capital expenditure of $2.6 billion during the year:

- The 7 million tonnes per annum Ulan Open Cut thermal coal project in Australia;
- The Tweefontein optimisation coal project in South Africa, which will, subject to receipt of final environmental approvals, produce 4 million tonnes per annum of thermal coal;
- The 6,000 tonnes per annum Fraser Morgan nickel mine and expansion to 40,000 tonnes per annum at Raglan nickel mine, both in Canada;
- Our share of capital to expand the joint venture Cerrejón thermal coal operation in Colombia to 40 million tonnes per annum;
- The 126,000 tonnes per annum greenfield Lady Loretta zinc project in the Mount Isa region, Australia; and  
- Mount Margaret, a 30,000 tonnes per annum copper project in Australia.
- During 2011, we announced significant increases in mineral resource estimates at the Antamina copper and zinc mine and Las Bambas and Coroccohuayco copper projects in Peru, the El Pachón copper project in Argentina and the Frieda River copper-gold project in Papua New Guinea.
 


Copper

Copper production was 3% lower than in 2010 as we enter a transition period in which a number of operations are approaching the end of their mine life and new lower cost production is on track to commence from the second half of 2012, notably at Antapaccay.  

We increased copper in concentrate production at Ernest Henry by 34% compared to 2010 to reach a total of 100,300 tonnes.  Production from the final high grade ore zone of the open pit operation and processing stockpiled ore boosted volumes, despite mining less material overall as a result of our ongoing project to convert the operation into an underground mine.

Our share of copper in concentrate production at Antamina increased by 11% to 112,600 tonnes, due to higher mill throughput as a result of de-bottlenecking initiatives and higher grades and recoveries.

Our Lomas Bayas operation benefited from increased run-of-mine (ROM) tonnes from the new Fortuna de Cobre pit as part of the Lomas 2 project. At Tintaya in Peru, we mined and processed higher grade sulphide ore resulting in increased copper production.

Production at our Alumbrera mine decreased by 17% to 116,700 tonnes compared to the previous year, primarily as a result of delayed access to high grade zones in the mine caused by geotechnical events in the latter part of 2010. Our share of production from the Collahuasi joint venture reduced by 10% to 199,400 tonnes mainly due to lower milled copper grades, extended maintenance and repairs to the main ore conveyor belt and adverse weather conditions in the first and third quarters of the year.  Our Mount Isa operations produced 6% less copper in concentrate than in 2010 due to lower grades and reduced production from the Enterprise mine.  At our Kidd underground mine in Canada, production of copper concentrate was affected by lower grades and volumes due to restricted access caused by two seismic events in the second half of the year.

Total gold production was marginally lower in 2011 at 517,900 ounces compared to 524,800 ounces in 2010 as improved ore grades at Ernest Henry largely offset lower head grades and recoveries at Alumbrera.

Our Mount Isa smelter and Altonorte custom smelter both achieved record production in 2011. However, total combined custom and mined copper cathode production decreased by 9% to 650,900 tonnes in 2011 as a result of the closure of the Kidd metallurgical plant in May 2010 and a temporary plant shutdown at the Townsville refinery in the first quarter of 2011 in response to a severe tropical cyclone in North Queensland.
 

Coal

We produced 85.3 million tonnes of coal on a consolidated basis in 2011, an increase of 7% compared to 2010.

Our Australian thermal coal operations produced 49.8 million tonnes of thermal and semi-soft coal, a 12% increase on the previous year, primarily due to the successful commissioning of the Mangoola open cut mine ahead of schedule and on budget in February.

The positive impact of additional volumes from Mangoola partly offset the flooding at the beginning of the year in Queensland and in New South Wales, the temporary suspension of operations at the Blakefield South mine due to an underground fire and interruptions to the Ulan longwall as a result of significant underground water, all of which occurred in the first quarter.  In the third quarter, production from the Ulan longwall had fully recovered and we recommenced development at Blakefield South.  

We maintained total coking coal production volumes for the year at 7.6 million tonnes, a similar level to 2010, as a result of the rapid recovery from flooding in Queensland during the first quarter.

Production from our South African thermal coal operations fell by 3% due to industrial action and the impact of our ongoing strategy to transition our operations from underground mines to three large and more efficient open cut complexes.

Cerrejón, our joint venture operation in Colombia, achieved record production, 7% higher than 2010, when excessive rainfall impacted production.

 
Nickel

We produced a record 105,925 tonnes of nickel in 2011, 15% more than the previous year.  Our Falcondo ferronickel operation in the Dominican Republic was responsible for the majority of this increase, producing 13,498 tonnes of nickel in ferronickel since reopening in February 2011 following a 30-month period of care and maintenance.  Falcondo’s restart outperformed our expectations, generating 8% more nickel than planned and operating at an annualised run-rate of almost 15,000 tonnes of nickel in ferronickel.

At our Nikkelverk refinery, we achieved an all-time record production of 92,427 tonnes of refined nickel, significantly exceeding the operation’s annualised nameplate capacity of 87,000 tonnes when we took over the business in 2006.   Copper metal production of 36,292 tonnes was slightly higher than last year, reflecting an increase in the amount of copper we processed from the polymetallic feed sent to Nikkelverk.

Our production at our Sudbury mines increased by 28% to 19,795 tonnes of nickel in concentrate compared to last year with our Nickel Rim South mine continuing to operate at full capacity.  The significant copper contained in Nickel Rim South ore and mining at Fraser’s copper zone, which restarted in February 2010, led to record mined copper in concentrate production of 49,887 tonnes from our Strathcona Mill, up 38% from 2010.  The Sudbury smelter produced 69,459 tonnes of nickel in matte, 6% less than last year, but in line with our plans for the year of 69,000 tonnes due to lower planned concentrate grades, a reduction in custom feed materials processed by the smelter and the impact of deferring a one-week maintenance shutdown from December 2010 to January 2011.  

Raglan mine operated at full capacity and treated 1.3 million tonnes of ore.  However, because of a planned period of lower nickel head grade, the production of nickel in concentrate fell 3% to 27,274 tonnes.  We expect head grade to decline further in 2012 in accordance with our mine plan.  Raglan’s head grade will improve significantly beyond 2013 with the development of the higher-grade Qakimajurq and Mine 2 Lower Zone deposits.  

At our Australian mines, we increased the volume of ore processed by 46% to 778,073 tonnes to offset the impact of mining more disseminated ore bodies with inherently lower nickel head grades. As a result, the production of nickel in concentrate from Xstrata Nickel Australasia increased slightly over 2010 to 17,034 tonnes.
 

Zinc

A strong operational performance at our Australian mines helped to partially offset the substantially lower volumes from the joint venture Antamina copper-zinc mine, where the mine plan favoured copper rich ores, and slightly lower volumes from the Canadian operations. Improved productivity at Mount Isa and McArthur River enabled us to raise zinc in concentrate volumes by 2%, despite the impact of weather-related issues in the first quarter of the year, and, at Mount Isa, electricity supply outages in the second half and lower grades.  Zinc in concentrate volumes at our Canadian operations fell slightly due to lower grades, despite achieving increased ore production. Overall zinc in concentrate volumes were just under 5% lower than in 2010.  

Zinc metal production increased at our San Juan de Nieva and Nordenham smelters by 2% and 6% respectively, following the commissioning in January of the new 20,000 tonnes per year direct leaching plant at Nordenham. These increases partially offset the impact of the closure of the Kidd Creek Metallurgical site in May 2010 and total zinc metal production decreased by 4%.  

The ore treated by our Mount Isa and McArthur River Mine operations increased by 8% and 6% respectively, partly offsetting the lower lead grades at Mount Isa. Total lead in concentrate decreased by 4% compared to 2010.

 
Alloys

Following a strong start to the year, we progressively reduced capacity utilisation at our ferrochrome smelters from the second quarter in response to weakening Chinese demand for South African ferrochrome.  Average capacity utilisation fell to an average of 72% for 2011 and ferrochrome volumes were 12% lower than in 2010.  Industrial action also impacted operating capacity at a number of operations during the second half.

The average European benchmark ferrochrome price for 2011 of $1.25 per pound remained at a similar level to the average price in 2010.  We recently settled the European benchmark price for the first quarter of 2012 at $1.15 per pound, 5¢ per pound lower than in the fourth quarter due to weaker demand from developed countries for stainless steel, the principal market for ferrochrome.

Following the depletion of all high grade, near-surface ore during the third quarter, all open pit production from our Eland platinum operation ceased and we started producing development ore from underground operations.  Reduced volumes also reflect the impact on grades of the transition from open pit mining and a slower than anticipated ramp-up of underground operations due to poor ground conditions.
