Rio Tinto: Second Quarter 2008 Operations Review

Posted on: Wednesday, 16 July 2008, 09:01 CDT

Commenting on the second quarter's production results, chief executive Tom Albanese said: "These strong results show that we are continuing to expand to meet rapid demand growth in the developing world. We have set quarterly production records for iron ore, mined copper and alumina, thanks to increasing investment in growth projects and a management commitment to deliver more tonnes faster, while maintaining our focus on safety and costs.

"The integration of Alcan is proceeding to plan and the business continues to perform well. I am particularly pleased to see how swiftly our Australian coal operations recovered from the first quarter floods.

"Chinese GDP is continuing to grow at around ten per cent per annum, demand is strong while supply remains constrained. Fundamentals, not financial speculation, are driving the record prices we are realising across aluminium, copper, iron ore and coal and we see the same trends continuing into the future."

-- Record quarterly global production of iron ore, up 13 per cent on the second quarter of 2007, recovering some of the shortfall from the cyclones in the first quarter.

-- Record quarterly iron ore production of 48 million tonnes in Australia, up 14 per cent (on a 100 per cent basis) compared with the second quarter of 2007, as the iron ore operations continue to expand their capacity.

-- Weighted average iron ore price increase of 85.7 per cent negotiated with Asian customers for 2008 contract shipments from the Pilbara.

-- Record quarterly mined copper production (for existing operations), up 15 per cent on the corresponding quarter of 2007.

-- Rio Tinto Alcan continues to perform well with bauxite production up 100 per cent, alumina up by 231 per cent and aluminium up by 374 per cent, compared with the second quarter of 2007, reflecting the acquisition of Alcan in the fourth quarter of 2007. On a proforma basis the respective increases for bauxite, alumina and aluminium were 11 per cent, nine per cent and one per cent.

-- The Sohar aluminium smelter in Oman began operating in June, on time and on budget, with first hot metal produced during the same month.

-- Australian thermal and coking coal production were up by 15 per cent and 25 per cent on the second quarter of 2007, recovering well from the heavy rainfall experienced in the first quarter.

-- Strong performance from the minerals businesses with borates production up 18 per cent and titanium dioxide feedstocks ten per cent higher than the second quarter of 2007.

-- Agreement signed to sell the Kintyre uranium property in Western Australia for $495 million, as part of the Group's overall $15 billion divestment target.

IRON ORE Rio Tinto share of production (000 tonnes) Q2 08 vs Q2 07 vs Q1 08 H1 08 vs H1 07 Hamersley 29,994 +7% +11% 57,011 +10% Hope Downs 1,732 n/a +222% 2,270 n/a Robe River 7,212 +4% +0% 14,401 +8% IOC (pellets and concentrate) 2,402 +39% +13% 4,521 +44% ----------------------------------------------------------------------

Pilbara operations

Rio Tinto negotiated record benchmark pricing levels for its iron ore production in 2008. Agreement was reached with major customers for a 96.5 per cent increase for lump ore and 79.88 per cent for fines for the 2008 contract year, representing an 85.7 per cent weighted average increase.

The split of production (based on 2007 production figures) is approximately as follows:

Fines Lump Hamersley (including Yandicoogina) 70% 30% Robe River (including Mesa J) 80% 20% ----------------------------------------------------------------------

During the second quarter Rio Tinto continued to sell iron ore into the spot market, and remains on track to meet its total spot sales target of up to 15 million tonnes for 2008 (two thirds 100 per cent owned operations, one third joint venture operations).

The Pilbara operations achieved record quarterly production, up 14 per cent on the corresponding quarter of 2007 (on a 100 per cent basis), following the ramp up of the Yandicoogina capacity expansion to 52 million tonnes per annum and the Hope Downs development (50 per cent owned by Rio Tinto). Hope Downs produced 3.5 million tonnes during the quarter as it continued to ramp up towards its 30 million tonnes per annum total capacity targeted for early 2009.

These records were achieved despite the significant gas outage caused by a major fire in June at Apache's processing plant, which provided two thirds of Rio Tinto's gas supply in the Pilbara. To date, Rio Tinto has mitigated the effect through reordering maintenance, arranging alternative suppliers and the use of higher priced diesel generation. Energy conservation was also prioritised to prevent a significant impact on shipped tonnage. Full return to gas supply is not expected for up to six months, hence management will continued to monitor the situation closely.

Expansion projects remain on schedule and on budget despite challenges posed by the Apache outage and weather conditions, in particular disruptions to the Cape Lambert wharf extension caused by cyclone-related ocean swell in the first quarter. Hope Downs South and Mesa A progressed well and the Brockman 4 development is expected to accelerate in the second half of 2008.

A number of significant capital projects were approved during the quarter, associated with the major expansion to a total capacity of 320 million tonnes per annum. An investment of $371 million (Rio Tinto share $350 million) will be made to automate the railway, which will lead to driverless trains operating on most of Rio Tinto's rail network across the Pilbara. The early acquisition of critical infrastructure for the expansion, and funds for the advanced studies of a new mine on the Western Turner Syncline deposit, were approved as part of a $667 million package (Rio Tinto share $492 million). An investment of $503 million (Rio Tinto share $397 million) will be made in a replacement power station for port and mine operations, which will significantly reduce emissions.

HIsmelt

The second quarter saw some significant improvements and milestones as the ramp up of the HIsmelt commercial plant continued. Following extensive maintenance in the first quarter, operational stability improved and record levels of hot metal production were achieved during the period.

Iron Ore Company of Canada

Pellet and concentrate production at the Iron Ore Company of Canada continued to be strong, reflecting ongoing debottlenecking efforts at the plant, as well as the absence of the labour stoppages of 2007.

(1) Includes Alcan data from 1 January 2007.

(2) Excludes Vlissingen (Netherlands,) which was divested in the first half of 2007 and Lannemezan (France) which was closed in the first quarter of 2008.

Half year production records were set across the board in the aluminium product group, following the acquisition of Alcan. Second quarter production of bauxite, alumina and aluminium increased sharply compared with the same quarter of 2007, reflecting the Alcan acquisition. Rio Tinto acquired the operating assets of Alcan with effect from 24 October 2007 and its production is included from that date. Proforma Rio Tinto Alcan production data for 2007 was published on 12 March 2008 and can be found on the Rio Tinto website.

Bauxite

Second quarter bauxite production was 100 per cent higher than the second quarter of 2007 and 11 per cent higher on a proforma basis. Second quarter bauxite production at Weipa was 14 per cent above the same quarter of 2007, reflecting increased capacity following the commissioning of the second shiploader.

During the quarter, Rio Tinto announced the approval of a $30 million feasibility study to develop a new bauxite operation to the south of the existing Weipa bauxite mine and port. With the approval of the new operation, Weipa's total bauxite production would increase from 18 million tonnes in 2007 to 35 million tonnes per annum.

Alumina

Second quarter alumina production was 231 per cent higher than the second quarter of 2007 and nine per cent higher on a proforma basis.

Expansion work on the Yarwun alumina refinery is progressing on budget and on track for its first shipment of alumina in the second half of 2010, with projected completion in the second half of 2011. Ramp up of production is expected to take 12 months following completion. The $1.8 billion project, announced in July 2007, will increase annual capacity from 1.4 million tonnes to 3.4 million tonnes by 2011.

The 1.8 million tonne per annum expansion of the Gove refinery is being commissioned and the ramp up continues, with 2.6 million tonnes expected to be produced in 2008. The target operating rate of between 3.4 million tonnes and 3.8 million tonnes per annum is expected to be achieved by the end of 2009.

Aluminium

Second quarter aluminium production was 374 per cent higher than the second quarter of 2007 and level on a proforma basis. During the quarter, Rio Tinto announced production cutbacks at its Tiwai Point smelter in New Zealand of up to 10%, due to low rainfall, reducing monthly output by 2,900 tonnes. This situation is expected to continue into the third quarter of 2008. In June a localised fire at the Anglesey smelter in Wales resulted in a loss of power across the smelter which is currently operating at reduced capacity. The shortfall from the above two incidents was offset by capacity creep at many of the Group's other smelters, notably in Canada.

The Sohar smelter in Oman began operating in June, on time and on budget, with first hot metal produced during the same month.

In April, Rio Tinto announced that it will proceed with an accelerated pre-feasibility study for an expansion of the Alma smelter in the Saguenay-Lac-Saint-Jean region of Quebec. The potential expansion would add approximately 170,000 tonnes to the current Alma smelter production of slightly more than 400,000 tonnes.

COPPER Rio Tinto share of production Q2 08 vs Q2 07 vs Q1 08 H1 08 vs H1 07 Kennecott Utah Copper Mined copper (000 tonnes) 60.2 +8% +35% 104.9 -4% Refined copper (000 tonnes) 49.3 -27% -5% 101.4 -26% Molybdenum (000 tonnes) 2.2 -41% -35% 5.7 -33% Mined gold (000 ozs) 92 -24% +34% 161 -29% Refined gold (000 ozs) 73 -50% -9% 154 -41% Escondida Mined copper (000 tonnes) 128.1 +22% +9% 245.3 +13% Refined copper (000 tonnes) 21.0 +7% +34% 36.8 -7% Grasberg JV Mined copper (000 tonnes) 7.1 +27% +10% 13.6 +19% Mined gold (000 ozs) 0 -100% n/a 0 -100% ----------------------------------------------------------------------

Kennecott Utah Copper

Copper grades recovered in the second quarter leading to higher mined production compared with both the previous quarter and the corresponding quarter of 2007. Changes in the mining sequence resulted in lower gold and molybdenum grades and production compared with the same quarter of 2007.

Copper grades at Bingham Canyon are expected to return to higher levels (comparable to 2006) during the second half. It takes two to three months for higher grade ore to report through to refined production. Molybdenum production in 2008 is expected to be approximately 20 per cent below the 2007 level following a decline in grades and recoveries. Molybdenum recovery is expected to improve through the second half of 2008 as operation of the new flotation cells is optimised.

Production decreases at the smelter and refinery from 2007 to 2008 are the consequence of lower head grades and lower concentrate production in the first quarter of 2008. A 26 day refinery shutdown is scheduled for July 2008 and an 11 day smelter maintenance shutdown is scheduled for August 2008.

In June Rio Tinto approved a $270 million investment in the construction of a new Molybdenum Autoclave Process (MAP) facility. The MAP facility is scheduled to begin operating in the third quarter of 2010 with full production estimated to be reached during 2011. It will enable 21,500 additional tonnes of molybdenum to be recovered over the current mine life to 2020. Studies are under way to extend the mine life of the Bingham Canyon mine to 2036.

Escondida

Mined copper for the quarter improved by 22 per cent compared with the corresponding period of 2007, attributable to higher volumes of leachate material. Production at Escondida has been impacted by haul truck and shovel maintenance and availability issues.

Grasberg

Copper grades improved at Grasberg from the previous quarter but low gold grades reduced Rio Tinto's share of gold production to nil in the second quarter of 2008.

Mining is expected to transition to a higher grade section of the Grasberg open pit in the second half of 2008.

Other operations

Lower copper and gold production at Northparkes was due to the treatment of lower grade stockpile material sourced from the open cut. Grade is expected to increase as the underground production from E26 Lift 2 North ramps up to full production, displacing the lower grade open cut material. Northparkes production for 2008 is expected to be more than 40 per cent below 2007.

Mined copper production at Palabora increased by close to 50 per cent compared with the same quarter of 2007, attributable to increased recovery rates from reprocessed secondary material.

Provisional pricing

At the end of the quarter the Group had 273 million pounds of copper sales that were provisionally priced at US 389 cents per pound. The final price of these sales will be determined during the second half of 2008. This compared with 270 million pounds of open shipments at 31 December 2007 provisionally priced at US 304 cents per pound.

DIAMONDS Rio Tinto share of production (000 carats) Q2 08 vs Q2 07 vs Q1 08 H1 08 vs H1 07 Argyle 2,992 -32% +38% 5,164 -35% Diavik 1,513 -23% +41% 2,584 -27% ----------------------------------------------------------------------

Argyle's production in the second quarter improved from the previous quarter but was 32 per cent below the corresponding quarter of 2007. Access to the high grade areas of the pit, which had been restricted due to geotechnical issues and wet weather earlier in the year, was re-established midway through the quarter resulting in improved feed grade and higher throughput. Variability in feed grades and production rates will continue as the open pit approaches the end of its life and the mine transitions to an underground operation.

Second quarter production at Diavik recovered substantially from the first quarter but was 23 per cent below the same quarter of 2007, primarily as a result of lower grades encountered in the A154S pipe. Also contributing to lower recovered grade was the commencement of processing of ore from the top of the A418 pipe.

During the quarter, Rio Tinto approved the Diavik small diamonds project at a capital cost of $50 million (Rio Tinto share $30 million). The project comprises additions and modifications to the ore processing plant to recover very small diamonds, reflecting good market demand for this product. The first recovery of small diamonds is expected to take place towards the end of 2009.

ENERGY US thermal coal Rio Tinto share of production (000 tonnes) Q2 08 vs Q2 07 vs Q1 08 H1 08 vs H1 07 Rio Tinto Energy America 30,947 +2% +1% 61,578 +1% ----------------------------------------------------------------------

Second quarter production was consistent with the preceding quarters. Increased production from the successful ramp up of the overland conveyor at Jacobs Ranch was offset by the effects of rail delays following severe flooding of the railway tracks in the Mid West.

Australian coal Rio Tinto share of production (000 tonnes) Q2 08 vs Q2 07 vs Q1 08 H1 08 vs H1 07 Rio Tinto Coal Australia Hard coking coal 2,038 +25% +95% 3,082 +0% Other coal 5,542 +15% +2% 10,990 +8% ----------------------------------------------------------------------

Hard coking coal production from the Queensland coal operations recovered significantly from the regional flooding during the first quarter.

In the Hunter Valley, production of semi soft coal increased to take advantage of stronger prices. Vessel queues in New South Wales have reduced allowing production to be in line with allocations.

An investment programme by the owners and operators of the coal ports at Newcastle and Dalrymple Bay on the eastern seaboard of Australia is expected to modestly increase capacity in the second half of 2008 and into 2009, followed by a major expansion of coal shipping capacity at Newcastle in 2010.

Uranium Rio Tinto share of production (000 lbs) Q2 08 vs Q2 07 vs Q1 08 H1 08 vs H1 07 Energy Resources of Australia 1,643 -26% -18% 3,654 -2% Rossing 1,505 +55% +13% 2,841 +26% ----------------------------------------------------------------------

Second quarter 2008 production at ERA's Ranger mine was 26 per cent lower than the comparative quarter of 2007. Heavy rains were experienced in 2007, preventing access to higher grade ore and ERA subsequently entered the 2008 wet season with lower than normal high grade stockpiles.

Higher grades at Rossing led to a 55 per cent improvement in production in the second quarter of 2008 compared with the same quarter of 2007, when a stripping campaign was being carried out.

MINERALS Rio Tinto share of production (000 tonnes) Q2 08 vs Q2 07 vs Q1 08 H1 08 vs H1 07 Borates 171 +18% +12% 324 +18% Titanium dioxide 405 +10% +14% 761 +6% ----------------------------------------------------------------------

Second quarter borates production rose by 18 per cent compared with the same quarter of 2007, with strong demand in Asia Pacific and Europe driving the processing plants to maximum capacity.

Titanium dioxide feedstock production increased during the quarter at both RBM and QIT.

EXPLORATION AND EVALUATION

Pre-tax expenditure on exploration and evaluation charged to the profit and loss account in the first half of 2008 was $401 million compared with $194 million in same period of 2007 with most of the increase attributable to the advanced evaluation studies on major growth projects. Pre-feasibility or feasibility work progressed on a number of these projects including Resolution (copper/gold, US), La Granja (copper, Peru), Potasio Rio Colorado (potash, Argentina), Simandou (iron ore, Guinea) and several Pilbara iron ore deposits.

The Sulawesi nickel laterite deposit in Indonesia (162Mt of resources at 1.62% Ni and 0.08% Co, refer to Rio Tinto press release on 28 May 2008) was declared a discovery and handed over to the Rio Tinto copper group.

High priority targets have been identified within the broader Lakeview nickel copper project in Minnesota. Initial drilling has identified significant disseminated sulphide mineralisation. The final hole of the winter programme returned 138m @ 1.6% Ni, 1.1% Cu including 28m @ 3.6% Ni, 2% Cu (refer to Rio Tinto Value & Growth seminar on 29 May 2008). An Order of Magnitude Study has been established for the project.

In June Rio Tinto announced that it had lodged mining lease applications for its Bunder diamond project in India, a vital step in the development of what could be the first world class diamond mine in India. It also announced the exploration target for diamond mineralisation at the Bunder project of 40 to 70 million tonnes at a grade of between 0.3 and 0.7 carats per tonne (refer to Rio Tinto press release on 23 June 2008).

The Serbian jadar lithium borates project Order of Magnitude study increased momentum during the quarter. The targeted mineralisation for the project was released showing a target of 80 -100 Mt @ 1.8-2.2% Li2O, 13.5 - 16.5% B2O3 (refer to Rio Tinto Value & Growth seminar on 29 May 2008) from the lower mineralised zone.

A summary of activity for the period is as follows:

DIVESTMENTS

Divestments continue on track and Rio Tinto remains committed to its $10 billion target for 2008.

In March 2008 Rio Tinto completed the sale of its 40 per cent interest in the Cortez gold mine in Nevada for $1.695 billion

In April 2008 Rio Tinto completed the sale of its 70.3 per cent interest in the Greens Creek silver, lead and zinc mine in Alaska to an affiliate of Hecla Mining Company, giving Hecla 100 per cent ownership. The sale price included cash consideration of $700 million and $50 million in Hecla stock.

On 10 July 2008, Rio Tinto announced that it had signed an agreement to sell the Kintyre uranium project located in Western Australia to a joint venture comprising Cameco Corporation and Mitsubishi Development Pty Ltd for $495 million.

Production data notes

(a) Rio Tinto acquired the operating assets of Alcan with effect from 24 October 2007; production is shown as from that date. The Rio Tinto assets and the Alcan assets have been combined under the Rio Tinto Alcan name.

(b) Rio Tinto held a 38.6% share in QAL until 24 October 2007; this increased to 80.0% following the Alcan acquisition

(c) Following a review of the basis for reporting aluminium smelter production tonnes, the data reported now reflects hot metal production rather than saleable product tonnes.

(d) Rio Tinto Alcan has an 80% interest in the Awaso mine but purchases the additional 20% of production

(e) Rio Tinto has a 22.9% shareholding in the Sangaredi mine but receives 45% of production under the partnership agreement.

(f) Includes beneficiated and calcined bauxite production.

(g) In view of Rio Tinto Energy America's responsibilities under a management agreement for the operation of the Colowyo mine, all of Colowyo's output is included in Rio Tinto's share of production.

(h) 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 first half of 2008.

(i) 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.

(j) Hope Downs started production in the fourth quarter of 2007

(k) Rio Tinto increased its shareholding in Rio Tinto Minerals - salt to 68.4% at the beginning of July 2007.

The Rio Tinto percentage interest shown above is at 30 June 2008.

Where Rio Tinto's beneficial interest in an operation has changed, as footnoted above, the share of production has been calculated using the weighted average interest over the relevant periods.

Where Rio Tinto has wholly divested an operation, no data is included in the Share of Production tables.
