Second quarter 2011 operations review

 

14 July 2011

 

Chief executive Tom Albanese said "Operations largely recovered from the severe weather impacts earlier this year, although some port and rail constraints remained. This quarter was also characterised by continued strong prices for most of our metals and minerals, but with worsening adverse exchange rates and some input cost pressures. Our growth programme was boosted by the successful $4 billion acquisition of Riversdale, giving us further options to develop our tier one assets."

      

·      Global iron ore production of 49 million tonnes attributable (62 million tonnes on a 100 per cent basis) was up 12 per cent on the second quarter of 2010 and up 17 per cent on the first quarter of 2011.

      

·      First half iron ore shipments of 110 million tonnes (100 per cent basis) from the Australian and Canadian operations were six million tonnes lower than 2010 first half following several cyclones, widespread flooding and a subsequent train derailment in the first quarter of 2011 in Western Australia.

 

·      Mined copper was down 24 per cent on the second quarter of 2010, primarily reflecting lower grades at Escondida and Kennecott Utah Copper.

 

·      Bauxite and alumina production improved by eight per cent and six per cent on the rain-impacted first quarter as the Queensland operations recovered. Bauxite production was up 11 per cent compared with the same quarter of 2010 whilst alumina and aluminium production were flat.

 

·      The Queensland coal mines steadily recovered from the severe rains of the first quarter. Hail Creek was the last Rio Tinto mine to lift force majeure on 12 May.

Ø Australian hard coking coal production was nine per cent higher than the first quarter but was down 26 per cent on the second quarter of 2010 due to the heavy rains.

Ø Australian thermal coal production was 18 per cent higher than the first quarter and five per cent higher than the second quarter of 2010. 

 

·      On 22 April, Rio Tinto, its subsidiary Simfer and the Government of Guinea signed a Settlement Agreement securing Rio Tinto's mining title in Guinea and paving the way for first shipment of iron ore by mid-2015. In recognition of the resolution of all outstanding issues and finalisation of new investment agreement terms, Simfer paid $700 million to the Guinean Public Treasury.

 

·      On 20 June, Rio Tinto's interest in Riversdale Mining Limited increased to 99.76 per cent. Riversdale was delisted on 7 July and the process has commenced to compulsorily acquire the remaining shares.

  

·      In the first half of 2011 Rio Tinto increased its interest in Ivanhoe Mines Ltd from 40.5 per cent to 46.5 per cent and participated in Ivanhoe's rights offering for a total consideration of $1.25 billion.

 

·      On 10 February, Rio Tinto announced a $5 billion capital management programme. By 13 July, 39 million Rio Tinto plc shares had been bought back at a total cost of $2.7 billion.

Pilbara marketing

Second quarter sales of 55 million tonnes (100 per cent basis) were two per cent lower than the corresponding quarter of 2010. Rail infrastructure recovered from the inclement weather in the first quarter but some speed restrictions remained following the train derailment in the first quarter.

 

Pilbara operations

The Pilbara mines recovered strongly from the first quarter and produced 59 million tonnes (100 per cent basis), only three per cent lower than the record fourth quarter of 2010. This was despite unseasonably wet weather throughout the second quarter. The strong performance was marred by the death in June of a scaffolding contractor at the East Intercourse Island terminal at Dampier port, the first such tragedy for the Pilbara operations since August 2003.

 

The capacity of the Pilbara system increased by five million tonnes to 225Mt/a at the end of the first quarter of 2011, following the completion of the first debottlenecking project at the Dampier port on time and on budget.

 

In May, the full bench of the Federal Court in Australia found in Rio Tinto's favour in ruling that neither of Rio Tinto's two major Pilbara rail lines should be declared open to mandated third-party access. 

 

In June, Rio Tinto announced that it will double its fleet of driverless haul trucks to ten at its iron ore operations in Western Australia and deploy them at Yandicoogina, the largest mine in the Pilbara. The move follows a two-year trial of Autonomous Haulage System technology on trucks at the West Angelas mine, which has performed well above expectations.

 

Pilbara expansion

The expansion of capacity of the Pilbara to 283 Mt/a by the second half of 2013 remains on track.  The feasibility study to expand the Pilbara to 333 Mt/a is well advanced and on track for a full decision in early 2012.

 

On 15 June, Rio Tinto announced that it is accelerating its iron ore expansion programme in the Pilbara with $676 million of funding for early works and procurement.  As a result, it is expected that the capacity expansion to 333 Mt/a will now be reached in the first half of 2015, six months earlier than previously planned.

 

Rio Tinto's integrated operations will be progressively upgraded as follows:

·      225 Mt/a - current operating capacity

·      230 Mt/a by end of Q1 2012 - Dampier port incremental (in implementation)

·      283 Mt/a by end of H2 2013 - Cape Lambert first 53 Mt/a increment (in implementation)

·      333 Mt/a by end of H1 2015 - Cape Lambert second 50 Mt/a increment  (in feasibility study)

 

Iron Ore Company of Canada (IOC)

Second quarter saleable iron ore production was 14 per cent lower than the same quarter of 2010 as a result of truck and labour availability issues, but 31 per cent higher than the first quarter of 2011 as progress was made to stabilise and improve production capability.  Concentrate for sinter production was maximised in the quarter to respond to market demand, and this resulted in lower pellet production relative to the first quarter. While the overall pellet capacity was temporarily reduced, it enabled significant plant maintenance work to be undertaken.

 

The Concentrator Expansion Project Phase 1, lifting capacity to 18 Mt/a, is on track for completion in late 2011 and Phase 2, improving the magnetite recovery circuit, is progressing as planned, with first production is expected in late 2012.

 

2011 production guidance

In 2011, Rio Tinto expects to produce in excess of 240 million tonnes (100 per cent basis) from its global operations in Australia and Canada.

Kennecott Utah Copper (KUC)

Ore milled in the second quarter was slightly above the first quarter as KUC continues to build upon the record milling rates established in 2010. Lower metals in concentrates in the second quarter and the first half were driven by lower copper and gold grades.

 

Molybdenum in concentrate production was higher than all the above comparable periods due to higher ore grades and recoveries.

 

As previously guided, production of copper, gold and silver is expected to remain lower in 2011 compared with 2010 as mining progresses through lower grade areas of the open pit.

 

Escondida

Second quarter mined copper production decreased 31 per cent compared with the same quarter of 2010, as a consequence of copper grade decreasing from 1.40 per cent to 1.06 percent.

 

Grasberg

Freeport is due to release its 100 per cent operating data for the second quarter on 21 July 2011.

Rio Tinto's share of joint venture copper in 2011 has been impacted by lower ore grades which substantially reduced the Rio Tinto share of production under the metal sharing agreement. The first quarter amounts reported as Rio Tinto's share of joint venture copper, gold and silver production were restated for changes to the full year metal sharing rate.

 

Northparkes

Mined copper production rose by 24 per cent compared with the same quarter of 2010 due to higher grades from the E48 block cave.

 

Palabora

Mined copper production increased by four per cent compared with the second quarter of 2010 due to increased processing of slag and improved hoisting rates.

 

Ivanhoe

On 21 June, Rio Tinto exercised its remaining warrants in Ivanhoe, increasing its ownership from 42.0 per cent to 46.5 per cent. Rio Tinto assumed management of the Oyu Tolgoi copper gold project in Mongolia following an agreement with Ivanhoe in December 2010. Under the terms of the agreement, Rio Tinto was also granted a subscription right, together with the ability to make on-market purchases, which, if exercised, would allow Rio Tinto to increase its ownership in Ivanhoe to 49 per cent on or before 18 January 2012.

 

2011 production guidance

In 2011, Rio Tinto share of mined and refined copper production is expected to be 539 thousand tonnes and 350 thousand tonnes, respectively.

Bauxite and alumina

Bauxite production was 11 per cent higher than the second quarter of 2010, notably at Weipa, driven by increased third party demand.

 

Alumina production is gradually recovering from the abnormally heavy rains between December 2010 and April 2011, which primarily impacted Queensland Alumina's production, affecting bauxite and coal quality, equipment reliability and freight costs.

 

The impact of the inclement weather is expected to lower Rio Tinto Alcan's underlying earnings by approximately $130 million in the first half of 2011 compared with the first half of 2010, due to lost alumina tonnage and higher costs in mining, refining and power generation, with a smaller impact continuing into the second half of 2011.

 

Aluminium

Aluminium production was marginally higher than the same quarter of 2010.

 

Production at Kitimat was reduced due to the closure of lines 7 and 8 in September 2010 in preparation for the modernisation project. Other movements included higher production from a gradual return to full capacity at the Lynemouth smelter in the UK.

 

Hydrology conditions in the Saguenay have returned to normal in 2011 following low snow and rain levels experienced in 2010.

 

2011 production guidance

In 2011, Rio Tinto's share of bauxite, alumina and aluminium production is expected to be 35.8 million tonnes, 9.2 million tonnes and 3.9 million tonnes, respectively.

Hard coking coal production recovered from the severe flooding in the first quarter but was 26 per cent below the second quarter of 2010. Production at Hail Creek improved by 71 per cent on the first quarter following the lifting of force majeure on 12 May. Kestrel production was 59 per cent lower due mainly to a planned one month longwall changeover during the quarter.

 

Semi-soft coking coal production was 31 per cent lower than the corresponding quarter of 2010, primarily due to product mix at Hunter Valley Operations (HVO), where thermal coal production was 64 per cent higher.

 

Thermal coal production was five per cent higher than the second quarter of 2010 and 18 per cent higher than the first quarter. Both Clermont and HVO recovered rapidly from the difficult conditions of the first quarter with HVO setting a monthly record for overburden removal during the second quarter.

 

Sales

Following the Japanese tsunami in the first quarter, the timing of some shipments priced in the 2010 Japanese Fiscal Year were pushed into the year commencing 1 April.  More than half of second quarter sales were priced at 2010 pricing levels.

 

2011 production guidance

In 2011, Rio Tinto's share of Australian hard coking, semi soft coking and thermal coal production is expected to be 8 million tonnes, 3 million tonnes and 18 million tonnes, respectively.

Processing at ERA resumed in June. The processing plant was shut from late January to mid June as a pro-active strategy to manage processed water inventories in the tailings dam following a sustained period of above-average rainfall.

 

Rössing production was lower than the second quarter of 2010 due to lower grades and lower extraction rates, although grades did recover slightly on the first quarter.

 

2011 production guidance

In 2011, Rio Tinto's share of uranium production is expected to be 7.5 million pounds.

Second quarter production at Argyle compared with the second quarter of 2010 was impacted by lower tonnes processed following the significant rainfall that occurred in March and April. Lower grades have compounded the production shortfall: in 2011 ore is being extracted from the North Pit where grades are significantly lower than the South Pit ore that was processed in 2010. In addition, a small volume of high grade development ore from the Underground was halted until the pit dewatering associated with heavy rain falls in the first quarter was completed.

 

Diamond production at Diavik was 11 per cent higher than the second quarter of 2010 and 32 per cent higher than the first quarter of 2011. This was driven by an increase in ore processed from mine sequencing which enabled access to higher grades from the A418 open pit.

 

Borates production increased by six per cent compared with the second quarter of 2010, in line with increased demand, and recovered from significant rainfall at both the US and Argentinean operations.

 

Titanium dioxide feedstocks production was seven per cent higher than the first quarter as Rio Tinto Fer et Titane's operations in Quebec recovered from the seasonal reductions in available power at its smelter operations.

 

Rio Tinto has historically entered into multi-year contracts for the sale of titanium dioxide feedstocks. As these contracts mature, they will be replaced by contracts with shorter term pricing mechanisms, providing the business with ongoing and increased exposure to current market pricing.

 

2011 production guidance

In 2011, Rio Tinto's share of production is expected to be as follows:

·      Diamonds - 13 million carats

·      Titanium dioxide feedstocks - 1.4 million tonnes

·      Borates - 0.5 million tonnes.

 

 

OTHER CORPORATE ACTIVITY

 

On 23 February, Rio Tinto announced the receipt of a binding offer from Imerys to acquire its talc business for an enterprise value of $340 million. The transaction is expected to complete during the third quarter of 2011.

 

On 20 June, Rio Tinto's interest in Riversdale Mining Limited increased to 99.76 per cent. Riversdale was delisted on 7 July and, under Australian Corporations Law, the process has commenced to compulsorily acquire the remaining shares in Riversdale that are not currently owned by Rio Tinto. Production from the Zululand Anthracite Colliery in South Africa, acquired as part of the transaction, has been excluded from this report.

 



EXPLORATION AND EVALUATION

 

Pre-tax and pre-divestment expenditure on exploration and evaluation charged to the profit and loss account in the first half of 2011 was $449 million compared with $214 million in the same period of 2010. During the first half of 2011, the Group realised $85 million (pre-tax) from the divestment of central exploration properties, compared with $67 million in the first half of 2010. This included the Sari Gunay gold property in Iran and the Altai Nuurs coal project in Mongolia.  

 

Exploration highlights

On 1 June, Rio Tinto and Chinalco formalised their exploration joint venture in China with the formation of Chinalco Rio Tinto Exploration Co Ltd (CRTX). The immediate priority for CRTX will be copper exploration, with coal and potash among other commodities potentially considered at a later date.

 

At the Amargosa bauxite project in Brazil, grid drilling was completed on the core resource block and metallurgical studies are in progress.  The Order of Magnitude Study remains on track for completion in the fourth quarter of 2011.

Production data notes

(a)           Mine production figures for metals refer to the total quantity of metal produced in concentrates, leach liquor or doré bullion irrespective of whether these products are then refined onsite, except for the data for bauxite and iron ore which represent production of marketable quantities of ore plus pellets.

(b)           Bauxite production at non-managed mines has been restated from a wet to a dry tonne basis, in line with the tonnes shown for Rio Tinto managed operations.

(c)           Rio Tinto has a 22.95% shareholding in the Sangaredi mine but receives 45.0% of production under the partnership agreement.

(d)           Production commenced at Clermont in the second quarter of 2010.

(e)           Through a joint venture agreement with Freeport-McMoRan Copper & Gold (FCX), Rio Tinto is entitled to 40% of additional material mined as a consequence of expansions and developments of the Grasberg facilities since 1998. Rio Tinto's share of production reflects actual production for the periods shown.

(f)            Rio Tinto's share of production includes 100% of the production from the Eastern Range mine. Under the terms of the joint venture agreement, Hamersley Iron manages the operation and is obliged to purchase all mine production from the joint venture.

(g)           In February 2011, Rio Tinto announced that it had received a binding offer for the purchase of 100% of its talc business.

The Rio Tinto percentage interest shown above is at 30 June 2011.

Rio Tinto's interests in the Brockville specialty alumina plant, Awaso, Rawhide, Antelope, Cordero Rojo, Decker and Spring Creek mines were sold in 2010. No data for these operations are included in the Share of Production table.

(a)           As a result of the initial public offering of Cloud Peak Energy Inc. on 20 November 2009, Rio Tinto held a 48.3% interest in the Antelope, Cordero Rojo and Spring Creek mines and a 24.1% interest in the Decker mine. These interests were formerly reported under Rio Tinto Energy America but are now managed by Cloud Peak Energy. Following a secondary public offering in December 2010, Rio Tinto completed the divestment of its entire interest in Cloud Peak Energy Inc. with an effective date of 15 December 2010.  Production data are shown up to that date.

(a)           Through a joint venture agreement with Freeport-McMoRan Copper & Gold (FCX), Rio Tinto is entitled to 40% of additional material mined as a consequence of expansions and developments of the Grasberg facilities since 1998. The 2Q 2011 results show the forecast from FCX's most recent five-year plan because FCX is not releasing its actual 100% operating data for 2Q 2011 until the release of its 2011 second-quarter results on 21 July 2011.

(b)           Net of smelter deductions.
