Production Report for the 12 months ended 31 December 2012
Highlights:
- Record annual thermal coal production resulting from the successful commissioning of the Ravensworth North, Ulan West and Ulan open cut projects in Australia, productivity improvements at Cerrej�n and the continued transition of our South African thermal coal operations into large-scale, low-cost operations;
- Record refined nickel volumes which benefited from the commissioning of Raglan mine�s Kikialik expansion and above capacity ferronickel production from Falcondo;
- A second consecutive year of record Australian zinc production volumes as a result of improved productivity levels;
- On-going de-risking of our capital programme as nine growth projects were successfully commissioned across our commodity portfolio, transforming volumes, costs and asset quality:
- We completed, on schedule, the first stage of the 8 million tonne per annum Ravensworth North thermal coal operation in New South Wales. The second stage, the expansion of the existing coal preparation plant, is on schedule for completion in 2013;
- Operations began at the 1.5 million tonne per annum Ulan open cut thermal coal mine in New South Wales and are on schedule to reach full production in 2013;
- Ernest Henry Mining commenced processing ore in September from Xstrata Copper�s nearby Mount Margaret mine in north-west Queensland, Australia, which will add around 30,000 tonnes of annual copper production to Ernest Henry�s production profile;
- Expansion of the concentrator and associated mine at our Antamina copper/zinc joint venture mine in Peru was successfully commissioned in the first quarter of 2012 and throughput rates are now consistently exceeding the planned 38% capacity increase;
- In September, ore production commenced, over one year ahead of schedule and on budget, at Xstrata Zinc�s high grade Lady Loretta mine in Queensland, Australia. Full-scale commercial mining will begin in mid-2013, delivering at full production an estimated 1.6 million tonnes of ore per annum;
- In early October, Xstrata Alloys commissioned the Tswelopele pelletizing and sintering plant, on time and on budget. The plant will reach full capacity of around 600,000 tonnes per annum of sintered pellets early in 2013;
- In November, Xstrata Copper commenced commercial grade production from our new Antapaccay mine, ahead of its progressive ramp up to nameplate processing capacity of 70,000 tonnes per day in the first half of 2013 and in line with budget. The mine is expected to produce an average of 160,000 tonnes of copper in concentrate per annum, plus gold and silver by-products, in the initial years of its more than 20 year projected life;
- In December, Xstrata Copper commissioned on schedule Lomas Bayas� Lomas II project which will extend the mine life by 16 years at existing production levels of 75,000 tonnes of copper cathodes per annum; and
- First ore was delivered six months ahead of schedule at our 1 million tonnes per annum mine expansion at George Fisher zinc mine.
- Construction was completed on Line 1 at the Koniambo ferronickel operation in New Caledonia. Following the Line 1 furnace heat up during February 2013, we expect to be generating commercial-grade ferronickel by the end of March, in line with our commissioning and ramp up plans. With metal production commencing in 2013, the site is well positioned to deliver the two-year production ramp-up to achieve its nameplate 60,000 tonnes of nickel in ferronickel per annum run rate by the end of 2014.
- We confirmed a definitive estimate of $5.2 billion for Xstrata Copper�s Las Bambas project in southern Peru, reconfirming the project�s status as a world class, Tier 1 copper asset that will deliver substantial value. Las Bambas is now in full construction phase and set to produce 400,000 tonnes of copper per annum from 2015 for at least the first five years of its more than 20 year projected life;
- We approved the $360 million (AUD360 million) Phase 3 expansion of Xstrata Zinc�s McArthur River Mine that will increase annual production to an average of 380,000 tonnes of zinc in conventional concentrate from 2014;
- We achieved further substantial increases in our copper Mineral Resources, mainly due to a significant 19% increase in total Mineral Resources at our Collahuasi joint venture in Chile to 9 billion tonnes; a 20% increase in total Mineral Resources at our El Pach�n project in Argentina to 3.3 billion tonnes; and a 27% increase in total Mineral Resources at our new Antapaccay mine in Peru to over 1 billion tonnes; and
- Xstrata�s shareholders approved the proposed merger between Glencore and Xstrata, subject to the necessary regulatory approvals being received.

Copper
Total mined copper production of 747,000 tonnes was 16% lower compared to 2011 as Xstrata Copper transitioned from older, end of life mines to new mines and expansions and addressed production challenges at the Collahuasi joint venture. Our production steadily increased during 2012 as we commissioned and/or ramped up five organic growth projects reaching an annualised production rate of approximately 900,000 tonnes in December 2012 compared to 700,000 tonnes in January 2012.
Copper in concentrate production at Antamina rose by 34%, increasing attributable volumes to 150,800 tonnes compared to 2011 due to increased mill throughput following the successful completion in March of a major capital investment project to expand processing capacity to 130,000 tonnes per day, along with improved grades and recoveries.
At Alumbrera mine, we increased copper in concentrate production by 16% to 135,700 tonnes compared to the previous year, primarily due to higher throughput, head grades and recoveries after a geotechnical event in 2011 restricted access to the pit.
At Lomas Bayas mine, we completed construction and successfully commissioned our Lomas II mine life extension project allowing us to maintain copper production in line with the previous year as ore from the new Fortuna de Cobre pit supplemented declining volumes from the original pit. Lomas II extends the life of Lomas Bayas by a further 16 years to at least 2028 at existing production levels of around 75,000 tonnes per annum of copper cathode.
Planned lower production at the Ernest Henry mine contributed 34,100 tonnes of copper in concentrate in 2012, a reduction of 66% compared to 2011, as the operation transitioned to underground mining following the completion of the open pit in December 2011. During the year, the new underground decline mine continued to ramp up to mining rates of 3 million tonnes per year and the satellite Mount Margaret open pit commenced production in September. Ernest Henry will produce an average of approximately 70,000 tonnes of copper in concentrate per annum from the combined underground mining and Mount Margaret open pit operations.
Production commenced in line with budget and schedule at the new Antapaccay mine in November, with the concentrator plant continuing to rapidly ramp up to its nameplate capacity of 70,000 tonnes per day. The long life Antapaccay mine is scheduled to produce an average of 160,000 tonnes of copper in concentrate per annum for at least its first five years of production and during the year we announced a further 27% increase in total Antapaccay Mineral Resources to over 1 billion tonnes. Antapaccay is replacing production from the adjacent Tintaya mine, where copper production decreased by 51% to 46,800 tonnes in 2012 due to lower grades and pit depletion as it reached the end of its life. Ore mining was completed in the Tintaya open pit by the end of January 2013.
Copper production at Collahuasi decreased by 38% compared to the previous year, due to planned lower grades and recoveries, adverse weather conditions, safety stoppages and an extended ball mill outage. A comprehensive business improvement plan initiated in July 2012 by shareholders was successfully completed by the end of 2012, resulting in more reliable operating performances and a strengthened organisational structure. Annualised production levels are expected to be restored to around 400,000 tonnes of copper per annum (on a 100% basis) in 2013. In February 2013, Collahuasi announced a further increase to Mineral Resources of 19% to 9 billion tonnes at an average grade of 0.81% copper confirming the world-class status of this deposit. Ore Reserves increased by 10% to 3.2 billion tonnes.
Gold production decreased by 19% to 421,600 ounces due to lower grades and the closure of the Ernest Henry open pit mine at the end of 2011 and the final phase of operations at Tintaya.
Total mined, integrated and third party copper cathode production decreased by 3% in 2012 as a result of reduced concentrate production at Ernest Henry for the Townsville refinery and the planned lower processing of oxide ores as Tintaya reached the end of its mine life.

Coal
Total consolidated coal production reached a record 90.4 million tonnes, 7% higher than in 2011.
Thermal coal production from our Australian operations, including semi-soft production, totalled 53.2 million tonnes, an increase of 7% from 2011. Increased volumes predominantly resulted from the restart of mining at Blakefield South, commencement of mining at Ravensworth North, Ulan West and Ulan open cut, and the return to full production at Rolleston following flooding in 2011. The increase was partially off-set by end of mine life closures at Ravensworth West and Westside during 2012 and at Baal Bone in late 2011.
Australian coking coal production was 6.9 million tonnes, 9% lower than the previous year. Increased production at Oaky Creek North was offset by engineering challenges with the new thin seam longwall at Oaky Creek No.1 mine. Remediation works are being finalised by the supplier, and production is ramping up.
Production from our South African thermal coal operations was 18.7 million tonnes in 2012, up 16% on the previous year, primarily due to the ramp up of Goedgevonden. A full year of production from the ATCOM East mine, combined with continued productivity improvements at our Impunzi and Tweefontein open cut mines, also contributed to the increase in production.
Our share of production from the Cerrej�n joint venture in Colombia increased 7% to reach 11.6 million tonnes, mainly as a result of productivity improvements arising from pit re-sequencing and shorter haul distances.

Nickel
Total nickel production was a record 106,873 tonnes in 2012, a further increase on the record volumes achieved in 2011. This increase was supported by a full year�s production of 15,186 tonnes of nickel in ferronickel from our Falcondo operation in the Dominican Republic, which operated 7% above its current nameplate capacity.
Production from our Sudbury mines in 2012 increased 3% to 20,425 tonnes of nickel in concentrate compared to the previous year, driven by higher nickel head grades, which improved 10% to 1.61% from 2011. Total copper in concentrate production from our Sudbury mines and mill increased 16% to 57,813 tonnes, reflecting a peak period of increased copper volume from Nickel Rim South, and production from the extension of Fraser mine�s copper zone in partnership with Vale. Nickel in matte from the Sudbury smelter was 4% higher than the previous year at 72,526 tonnes and the second highest level on record as a result of higher capacity utilisation from acquiring and processing additional third-party feed.
Our Raglan mine operated at full capacity and treated 1.3 million tonnes of ore while generating a 5% increase in nickel in concentrate to 28,613 tonnes over the previous year due to a 5% increase in nickel head grade to 2.50%, primarily due to the commissioning of the Kikialik mine in early 2012.
At our Australian mines, we processed 726,029 tonnes of ore in 2012, 7% lower than the previous year, reflecting the decision to place the lower-grade Cosmos mine on care and maintenance in the third quarter of 2012 in response to adverse market conditions. The impact of this move was partly offset by solid performance from the Sinclair mine, where mined production was 21% above plan.
Our Nikkelverk refinery in Norway produced 91,687 tonnes of nickel in 2012, in line with the previous year�s production. Copper metal production of 37,891 tonnes was up 4% from the previous year, reflecting improvements in copper processing capacity.

Zinc
Total zinc in concentrate production was slightly higher in 2012 than in 2011. Our Australian operations achieved record volumes in 2012, with an 8% increase in zinc in concentrate production compared to the record volumes reached in 2011. The higher Australian volumes offset lower output at our Brunswick and Perseverance mines in Canada, which was mainly due to lower grades as ore reserves approach the end of their lives, and lower zinc production at Antamina, where the mine plan continues to operate in a predominantly copper ore zone.
Refined zinc metal production at our smelters was in line with 2011 volumes.
Total lead in concentrate production increased by 9% compared to 2011, mainly as a result of record volumes of lead in concentrate production at Mount Isa Mines. Improved lead ore grades at our Australian operations more than offset lower head grades at our Canadian operations.
Total refined lead metal production was 12% higher than 2011, boosted by higher lead production at our Mount Isa operations and improved shipping schedules for lead bullion to our UK lead refinery.

Total attributable ferrochrome production during 2012 was 938,426 tonnes, 8% lower than in 2011. Our furnaces operated at 66% of their capacity in response to weak market demand and as a result of participating in the national energy supplier, Eskom�s, power buy-back programme. Volumes were further reduced during the high electricity tariff winter months, at the end of which industrial action impacted the ramp-up of production.
The average European benchmark ferrochrome price for 2012 of $1.21 per pound was slightly lower than the average price in 2011. The European benchmark price for the first quarter of 2013 has been settled at $1.125 per pound, a 2% increase on the $1.10 achieved for the fourth quarter of 2012.
Tswelopele, our 600,000 tonnes per annum pelletizing and sintering plant, was commissioned on schedule and within budget in October and reached design production capacity within the first month of operation.
During 2012, PGM volumes of 140,381 ounces were 10% lower than in 2011 as Eland continued its transition from an open cast to underground operation and as a result of industrial action. The two shafts at Eland have commenced ramping up and full capacity of 5,400,000 tonnes per annum will be reached in 2018. At our Mototolo joint venture, a record 2,466,362 tonnes was achieved, 7% higher than in 2011 as a result of continued productivity improvements.
