Rio Tinto delivers strong first quarter production

15 April 2014

Rio Tinto chief executive Sam Walsh said "Rio Tinto has started the year with a series of performance records as we continue to drive productivity gains across our operations. Our Pilbara iron ore business has again set new benchmarks for production, shipments and rail volumes for the first quarter and we are well on track to reach nameplate capacity of 290Mt/a by the end of the first half of 2014. Our mined copper production benefited from higher ore grades at Kennecott Utah Copper and production ramp up at Oyu Tolgoi and we also had a record first quarter for bauxite, primarily driven by higher production at Weipa."

Highlights

Semi-soft and thermal coal	mt (RT share)	6.8	+12%	+4%
Titanium dioxide feedstock	kt (RT share)	389	-9%	+8%

·      Record first quarter iron ore production, shipments and rail volumes. Shipments from the Pilbara exceeded production in the quarter, despite the impact of tropical cyclone Christine which closed our ports for three days at the end of 2013 and affected the progressive recovery of rail and ports into January. The full ramp up is well on track to achieve nameplate capacity of 290 Mt/a by the end of the first half of 2014.

·      Mined copper benefited from higher grades at Kennecott Utah Copper and production at Oyu Tolgoi. This more than offset the elimination of production from copper assets divested in 2013.

·      Record first quarter bauxite production and shipments were driven by a ramp up of production at the Weipa mine in Australia to feed the newly expanded Yarwun alumina refinery.

·      Production of coal improved in the first quarter of 2014 compared to the same period in 2013 due to the productivity improvement programme.

·      Exploration and evaluation expenditure was $155 million in the first quarter of 2014, sustaining the savings achieved in 2013 whilst progressing the highest priority future growth projects.

·      On 13 March 2014, Rio Tinto launched the latest phase of its industry-leading Mine of the Future™ technology and innovation programme.  The Processing Excellence Centre (PEC) is a state-of-the-art facility that harnesses 'big data' in real time at seven Rio Tinto copper and coal operations across the globe to maximise productivity and improve performance.

IRON ORE

Rio Tinto share of production (million tonnes)

	Q1 2014	vs Q1 2013	vs Q4 2013
Pilbara Blend Lump	13.3	+10%	-3%
Pilbara Blend Fines	19.6	+8%	-4%
Robe Valley Lump	1.4	+13%	-13%
Robe Valley Fines	2.9	+10%	-1%
Yandicoogina Fines (HIY)	13.4	+10%	-7%
IOC (pellets and concentrate)	1.8	-12%	-24%

Global iron ore production of 66.4 million tonnes (Rio Tinto share 52.3 million tonnes) and shipments of 66.7 million tonnes set new first quarter records. Rio Tinto's share of production was eight per cent higher than in the same period of 2013.

Pilbara operations

First quarter production of 63.4 million tonnes (Rio Tinto share 50.6 million tonnes) was ten per cent higher than the same period in 2013 and set a new first quarter record, driven by productivity improvements and the continued ramp up towards 290Mt/a.

Production in the first quarter was below fourth quarter levels due to disruption caused by seasonal weather patterns. Severe tropical cyclone Christine closed Rio Tinto's Pilbara ports and coastal rail operations in late December. Heavy rainfall associated with this cyclone and other adverse weather conditions in January and February impacted across mine, rail and port operations.

Following early completion of infrastructure works associated with the 290 Mt/a project last year, the ramp up to nameplate capacity of 290 Mt/a continued in the first quarter of 2014.  The newly commissioned system achieved daily equivalent run-rates at or above nameplate capacity on certain days in the first quarter, although performance of the integrated system remains variable.  The commissioning remains on schedule to be complete by the end of the first half of 2014. 

Pilbara marketing

First quarter sales of 64.2 million tonnes (100 per cent basis) were 17 per cent higher than the same period of 2013, setting a new first quarter record. Sales in the first quarter continued to exceed production due to the drawdown of iron ore inventories built at Pilbara mine sites in previous years to facilitate the rapid ramp up of shipments to 290Mt/a.

Pilbara expansion

Expansion of the port, rail and power infrastructure capacity to 360 Mt/a remains on track for completion by the end of the first half of 2015.

In November 2013, Rio Tinto set out its breakthrough pathway to optimise the growth of mine capacity towards 360 Mt/a at a target all-in capital intensity of between $120-130 per tonne (100 per cent basis), significantly lower than originally planned. A series of low-cost brownfield expansions will bring on additional tonnes to feed the expanded infrastructure. From a base run rate of 290 Mt/a by the end of the first half of 2014, mine production capacity is planned to increase by more than 60 million tonnes a year between 2014 and 2017. The majority of the low-cost growth will be delivered in the next two years, with mine production of more than 330 million tonnes (100 per cent basis) expected from the Pilbara in 2015.

Iron Ore Company of Canada (IOC)

First quarter saleable production was 12 per cent lower than the same period of 2013 due to the exceptionally cold weather associated with a polar vortex experienced in North America.

Pellet sales were 14 per cent higher than in the first quarter of 2013. Concentrate sales were 33 per cent lower than the first quarter of 2013 as a result of the unusually cold weather.

2014 production guidance

2014 production guidance remains unchanged. Rio Tinto expects to produce approximately 295 million tonnes (100 per cent basis) from its global operations in Australia and Canada, subject to weather constraints. The full ramp up in the Pilbara to nameplate capacity of 290 Mt/a is expected to be delivered by the end of the first half of 2014. The drawdown of iron ore inventories at the Pilbara mines will continue to allow shipments to ramp up ahead of production, with around five million tonnes of inventory drawdown expected during the year.

COPPER

Rio Tinto share of production

Mined gold (000 oz)	22.0	N/A	-11%

Kennecott Utah Copper

First quarter production of copper and gold contained in concentrates improved significantly on the same period in 2013, reflecting higher grades at the mine and improved recoveries at the concentrator due to the flotation expansion completed in the third quarter of 2013. Molybdenum production in the first quarter was lower than the first quarter of 2013 due to lower grades.

Copper cathode production for the first quarter was five per cent higher than in the same period in 2013. A 65-day smelter shutdown is planned to start in September which will impact cathode production in the second half of 2014.

Escondida

Mined copper production decreased eight per cent on the first quarter of 2013. This decrease was driven by lower ore grades, partially offset by higher mill throughput.

Oyu Tolgoi / Turquoise Hill Resources

Production for the first quarter was 25.3 thousand tonnes of copper and 65.6 thousand ounces of gold in concentrates (Rio Tinto share 8.5 thousand tonnes and 22.0 thousand ounces). Higher grades compared to last quarter were more than offset by lower throughput due to post-commissioning issues which required a shutdown of one grinding circuit line to complete inspections and repairs during the quarter. These are now complete and full production recommenced in March.

Customer collections of concentrate from the Chinese bonded warehouse continued to ramp up, with the sale of 13.1 thousand tonnes of copper and 27.8 thousand ounces of gold in concentrates (100 per cent basis) recognised in the first quarter of 2014. Monitoring customer collections and inventory levels will help ensure that inventories approach appropriate levels by the end of 2014.

Grasberg

Rio Tinto does not expect 2014 production to exceed the metal attributable to its joint venture partner. Accordingly, Rio Tinto expects its share of joint venture production to be zero for the year.

2014 production guidance

2014 production guidance remains unchanged. Rio Tinto's share of mined and refined copper production is expected to be approximately 570,000 tonnes and 260,000 tonnes, respectively. Mined copper guidance is approximately 60 thousand tonnes lower than actual production in 2013. Around 50 thousand tonnes of this reduction is due to divestments completed in 2013, with the remainder driven by the smelter shut and a decrease in full year ore grades at Kennecott Utah Copper, expected to be partially offset by increased production at Oyu Tolgoi.

ALUMINIUM

Rio Tinto share of production (000 tonnes)

	Q1 2014	vs Q1 2013	vs Q4 2013
Rio Tinto Alcan
Bauxite	10,044	+5%	-12%
Alumina	1,856	+17%	-3%
Aluminium	832	0%	-2%
Other operations
Gove alumina refinery	537	-10%	-20%

In November 2013, Rio Tinto announced the suspension of alumina production at Gove. The Gove alumina refinery is being progressively ramped down, with each of its three production stages being suspended independently. One stage was successfully ramped down in February. The second stage was suspended in early April and the third stage is due to be suspended in June. The refinery will move to care and maintenance from July 2014. It continues to be reported separately from Rio Tinto Alcan.

Bauxite

Bauxite production set a new first quarter record and was five per cent higher than the same period in 2013. Production was lower than in the fourth quarter of 2013 due to maintenance activities which took place in Guinea and Brazil, adverse weather experienced at the Weipa mine from ex-tropical cyclone Gillian and the Gove bauxite mine adjusting to the curtailment of production at the Gove alumina refinery.

Alumina

First quarter alumina production was 17 per cent higher than the same period in 2013 due to the non-recurrence of weather conditions experienced due to ex-tropical cyclone Oswald which impacted production at both Queensland alumina refineries in the first quarter of 2013.

Aluminium

First quarter aluminium production was in line with the same period in 2013.  Production was slightly lower than in the fourth quarter of 2013 due to the shutdown of the Shawinigan smelter at the end of November 2013 and the partial curtailment of production at the Boyne smelter in the first quarter of this year in response to high Queensland electricity prices over the summer months.  These were partially offset by production from the newly inaugurated AP60 plant, which reached full capacity in December 2013.

2014 production guidance

Rio Tinto's share of bauxite, alumina and aluminium production is expected to be 41 million tonnes, 8.0 million tonnes (previously 8.1 million tonnes) and 3.4 million tonnes, respectively. This excludes alumina production from the Gove alumina refinery, which is in the advanced stages of being suspended.

ENERGY

Coal

Rio Tinto share of production (000 tonnes)

	Q1 2014	vs Q1 2013	vs Q4 2013
Rio Tinto Coal Australia
Hard coking coal	1,814	+18%	-20%
Semi-soft coking coal	936	-10%	+1%
Thermal coal	5,806	+17%	+6%
Rio Tinto Coal Mozambique
Hard coking coal	59	-47%	-60%
Thermal coal	54	-51%	-58%

Hard coking coal production in Australia was 18 per cent higher than the first quarter of 2013 due to improved production from the Kestrel mine. The Kestrel mine coal handling preparation plant was shut for upgrade works in the first quarter of 2013 as part of the Kestrel mine extension that was completed during the second half of last year. Hard coking coal production was 20 per cent lower than in the fourth quarter due to higher rainfall, in keeping with seasonal trends.

Semi-soft coking coal production was ten per cent lower than the first quarter of 2013, largely due to a planned change in the production profile.

Australian thermal coal production increased by 17 per cent compared with the first quarter of 2013 due to continued productivity gains achieved in the Hunter Valley and producing thermal coal from a processing plant by-product stream at Hail Creek.

The sale of Rio Tinto's 50.1 per cent interest in the Clermont Joint Venture for $1.015 billion announced in October 2013 is expected to complete in the first half of 2014.

First quarter production in Mozambique was affected by rail and port constraints, as well as operational changes in response to security considerations. Operations have been moved to a day shift only, and were suspended for a period in February 2014.

Uranium

Rio Tinto share of production (000 lbs)

	Q1 2014	vs Q1 2013	vs Q4 2013
Energy Resources of Australia	0	-100%	-100%
Rössing	644	-34%	-12%

Process plant operations at ERA remain suspended following a leach tank failure in December 2013. ERA is now implementing its restart readiness plan based on the independent expert's recommendations on asset integrity and maintenance. The restart of processing operations remains subject to the receipt of regulatory approvals. ERA continues to work closely with regulatory authorities and key stakeholders in order to gain approval to restart processing operations.

First quarter production at Rössing was 34 per cent lower than the same period of 2013. This was a result of reduced mill throughput and recoveries following the temporary plant stoppage caused by a December 2013 leach tank failure. Processing restarted on 11 January 2014 and the ramp up to full capacity was completed during the quarter.

2014 production guidance

Rio Tinto's expected share of Australian hard coking coal production has decreased marginally to 8.2 million tonnes (previously 8.5 million tonnes) with a consequent expected increase in thermal coal production to 16.7 million tonnes (previously 16.5 million tonnes; excluding production from Clermont).  This change is driven by prioritising production of thermal coal from a processing plant by-product stream at Hail Creek which delivers increased margins in the current price environment. Semi-soft coking coal production guidance remains unchanged at 3.0 million tonnes.

Rio Tinto's share of uranium production at Rössing in 2014 is expected to be 3.3 million pounds. Production at ERA in 2014 remains subject to the timing of regulatory approvals for restarting processing operations.

DIAMONDS & MINERALS

Rio Tinto share of production

	Q1 2014	vs Q1 2013	vs Q4 2013
Diamonds (000 carats)
Argyle	2,461	+24%	-22%
Diavik	1,119	-4%	-10%
Murowa	69	-12%	-34%
Minerals (000 tonnes)
Borates - B2O3 content	126	+13%	+4%
Titanium dioxide feedstock	389	-9%	+8%
Salt (000 tonnes)	1,586	+0%	-16%

Diamonds

At Argyle, carats recovered were 24 per cent higher than the first quarter of 2013 reflecting higher grade ore from the underground mine and the processing of highly concentrated tailings. Production in the first quarter of 2014 was 22 per cent lower than in the fourth quarter last year due to the exhaustion of all remaining open pit stockpiles in the fourth quarter and significant wet weather experienced in January and February which temporarily impacted mining and processing operations. The underground project remains on track, with the second crusher due for completion early in the third quarter this year.

Diavik had a strong operational performance in the first quarter with a 17 per cent increase in ore processed. However, due to a greater proportion of mined and processed ore coming from the lower grade A154N pipe in the quarter, carats recovered were four per cent lower than the first quarter of 2013.

First quarter carats recovered at Murowa were lower than the same period in 2013 due to lower grades, slightly lower ore processed and the impact of wet weather on mining operations, which were partially offset by processing previously stockpiled material.

Minerals

Borates production in the first quarter was 13 per cent higher than the same quarter in 2013 in response to higher sales demand in the quarter and in preparation for the commissioning of the new modified direct dissolving of kernite (MDDK) process plant in the third quarter of 2014.

Rio Tinto Iron and Titanium (RTIT)

Titanium dioxide feedstock production was nine per cent lower than the first quarter of 2013 reflecting softer market demand. The planned rebuild of one of nine furnaces at Rio Tinto Fer et Titane (RTFT) continues to be postponed until market conditions for high grade titanium dioxide feedstock improve. First quarter production in 2014 increased eight per cent compared to the fourth quarter last year reflecting production increases at Richards Bay Minerals to match shipments of chloride feedstock.

Salt

First quarter production of salt was consistent with the same quarter of 2013, aligned with demand during the period.

2014 production guidance

2014 production guidance remains unchanged. Rio Tinto's share of production is expected to be 1.5 million tonnes of titanium dioxide feedstocks, 0.5 million tonnes of boric oxide equivalent and 16 million carats of diamonds.

CORPORATE

On 13 January 2014, Rio Tinto announced that it had maintained its holding in Turquoise Hill Resources at approximately 50.8 per cent following the successful completion of the approximately $2.4 billion rights offering which was fully subscribed. The proceeds of the rights issue were used to repay loans outstanding to Rio Tinto, and resulted in a $1.2 billion reduction in Rio Tinto's consolidated net debt.

On 12 February 2014, Rio Tinto announced that it had granted an option to LNG Canada to acquire or lease a wharf and associated land at its port facility at Kitimat in British Columbia, Canada. The agreement provides LNG Canada with a staged series of options payable against project milestones. The financial arrangements are commercially confidential.

On 7 April 2014, Rio Tinto announced that it would gift its 19.1 per cent shareholding in Northern Dynasty Minerals Ltd (Northern Dynasty), owner of the Pebble Project, to two local Alaskan charitable foundations. The decision follows the strategic review of Rio Tinto's interest in Northern Dynasty announced last year, which concluded that the Pebble Project does not fit with Rio Tinto's strategy.

EXPLORATION AND EVALUATION

Pre-tax and pre-divestment expenditure on exploration and evaluation charged to the profit and loss account in the first quarter of 2014 was $155 million compared with $257 million in 2013. Of the first quarter 2014 expenditure, approximately 34 per cent was incurred by the Copper Group, five per cent by Iron Ore, 19 per cent by Energy, 17 per cent by Diamonds and Minerals, one per cent by Rio Tinto Alcan and the balance by Central Exploration. There were no significant divestments of central exploration properties in the first quarter of 2014 or 2013.

(c) The Shawinigan smelter ceased production on 29 November 2013.
(d) Rio Tinto started production at the Arvida AP60 Technology Centre in the fourth quarter of 2013.
(e) 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 concentrates and pellets.
(f) Rio Tinto has a 22.95% shareholding in the Sangaredi mine but benefits from 45.0% of production.
(g) In October 2013, Rio Tinto announced that it had reached a binding agreement for the sale of its 50.1% interest in the Clermont Joint Venture.
(h) Hail Creek commenced production of thermal coal from reprocessed coking coal reject following completion of a successful trial in the third quarter of 2013.
(i) 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 does not expect 2014 production to exceed the metal attributable to its joint venture partner. Accordingly, Rio Tinto's share of joint venture production was zero for the first quarter 2014.
(j) Rio Tinto owns a 33.52% indirect interest in Oyu Tolgoi through its 50.79% interest in Turquoise Hill Resources Ltd. Production included in the table is from 1 May 2013.
(k) 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.
(l) Quantities comprise 100% of Rio Tinto Fer et Titane and Rio Tinto's 74% interest in Richards Bay Minerals (RBM).
(m) ERA production has been restated from 'produced ready for packing' to 'drummed' U3O8, in line with production reported by Energy Resources of Australia Ltd to the Australian Stock Exchange (ASX).

(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 first quarter 2014 results show the forecast from FCX's most recent five-year plan, because FCX is not releasing its actual 100% operating data for the first quarter 2014 until the release of its 2014 first-quarter results on 24 April 2014. (b) Rio Tinto share of Grasberg production is 40% of the expansion. (c) Net of smelter deductions.
Rio Tinto percentage interest shown above is at 31 March 2014. The data represent full production and sales on a 100% basis unless otherwise stated.
