NEWS RELEASE bhpbilliton Release Time IMMEDIATE Date 23 February 2016 Number 4/16 BHP BILLITON RESULTS FOR THE HALF YEAR ENDED 31 DECEMBER 2015 The health and safety of our people and the communities in which we operate always come first. We are committed to addressing the consequences of the tragedy at our joint venture, Samarco. Underlying EBITDA(1) of US$6.0 billion and an Underlying EBITDA margin(2) of 40% for the December 2015 half year, despite significantly weaker commodity prices which had a negative impact of US$7.8 billion. Productivity continues to improve. Black Hawk well costs declined by 30%, Western Australia Iron Ore and Queensland Coal unit cash costs declined by 25% and 17%, respectively, and grade-adjusted unit cash costs at Escondida(3) were broadly unchanged. Capital and exploration expenditure(4) decreased by 40% to US$3.6 billion. Reflecting the Group’s rising capital productivity and lower spend in Onshore US, we now expect to invest US$7.0 billion in the 2016 financial year and US$5.0 billion in the 2017 financial year. Robust operating performance, the flexibility of our investment program and a targeted reduction of working capital supported free cash flow(2) of US$1.2 billion. Our strong balance sheet has been maintained, with net debt(2) of US$25.9 billion broadly unchanged from December 2014 despite weaker prices and significant dividend payments. While we were prepared for lower prices across our commodities, we now believe the period of weaker prices and higher volatility will be prolonged. From a position of strength, we have adopted a dividend policy that further protects our balance sheet and ensures financial flexibility. The dividend policy provides a minimum 50% payout of Underlying attributable profit at every reporting period. The Board will assess, every reporting period, the ability to pay amounts additional to the minimum payment, in accordance with the capital allocation framework. The Board has determined to pay an interim dividend of 16 US cents per share which is covered by free cash flow. This comprises the minimum payout of 4 US cents per share and an additional amount of 12 US cents per share, reflecting differences between Underlying attributable profit and free cash flow during the period.

News Release Results for the half year ended 31 December 2015 BHP Billiton Chairman, Jac Nasser, said: “Our purpose is to deliver consistent and sustainable shareholder value. Since the merger of BHP and Billiton in 2001, we have returned a total of US$77 billion in cash to shareholders, more than any other company in this sector. “At the same time, BHP Billiton understands the fundamental importance of maintaining a strong balance sheet. The changes to the dividend policy announced today reflect the Board’s assessment of the outlook for commodities and the increased financial flexibility this demands. While the continued development of emerging economies will underpin longer-term demand growth for commodities, we now believe the period of weaker prices and higher volatility will be prolonged. The adoption of a dividend payout ratio will further support BHP Billiton’s financial strength, while providing flexibility at the bottom of the cycle and ensuring discipline at the top. “We have not made these changes lightly. They are a determined response to changing markets that will also help us take advantage of the significant opportunities ahead. We remain strongly committed to returning cash to our shareholders and in every reporting period, the Board will assess the possibility of returning additional cash over that implied by the 50 per cent payout ratio, as we have done this period.” BHP Billiton Chief Executive Officer, Andrew Mackenzie, said: “Slower growth in China and the disruption of OPEC have resulted in lower prices than expected. However, our company remains resilient with assets that generate free cash flow through the cycle and a strong balance sheet. “Our new dividend policy and transparent capital allocation framework are part of a broader strategy to help BHP Billiton manage volatility. We have already responded decisively to the changed conditions. The divestment of US$7 billion of assets and the demerger of South32 leaves us with a focused portfolio of large, low-cost, long-life assets in a set of favoured commodities. We are operating our assets more productively with US$10 billion of gains achieved since 2012. We expect to realise a further US$2.1 billion of gains in the 2016 financial year, when adjusted for the impact of lower grades at Escondida. We will also reduce capital expenditure in the 2016 and 2017 financial years by a total of US$3.5 billion, while retaining a suite of high-return, value-enhancing projects. “With improved financial flexibility and a portfolio of high-return growth options, we are well positioned to grow shareholder value and cash returns over the long term.” In relation to Samarco, he said: “Everyone at BHP Billiton has been deeply affected by the tragedy at Samarco. Supporting the response efforts, rebuilding communities and restoring the environment impacted by the dam failure remains a priority and substantial progress has been made. Discussions on an agreement with the authorities for managing and funding long-term environmental and socio-economic rehabilitation plans are ongoing.” The health and safety of our people and the communities in which we operate always come first In the December 2015 half year there were no fatalities at our operated sites and we reported a Total Recordable Injury Frequency of 4.4 per million hours worked. We continue to focus on managing and controlling fatal risks and eliminating serious injuries across our business. Responding to the tragedy following the failure of the Fundão tailings dam at Samarco on 5 November 2015 is a priority for BHP Billiton. Our team in Brazil are focused on doing everything they can to support the response efforts, repair and maintain existing dams, rebuild communities and restore the environment impacted by the dam failure. Sadly, authorities have confirmed 17 fatalities, of which five were members of the community and 12 were people who were working on the dams at the time of the dam failure. In addition, two people who were working on the dams remain unaccounted for. All of the families from Bento Rodrigues and Barra Longa affected by the dam failure have been accommodated in rental housing or relatives’ homes, with the exception of those who preferred to stay in a hotel. Debit cards have been distributed to those affected in order to provide immediate financial relief. Samarco and the authorities are continuing to ensure availability of food, water and emergency supplies. 2

BHP Billiton Results for the half year ended 31 December 2015 Samarco has also been active in addressing the environmental impact of the dam failure. Such actions include the construction of dikes to reduce the potential for further tailings inputs to the River Doce, revegetation measures to reduce erosion and water quality monitoring stations throughout the River Doce system. Samarco has engaged world-class consulting specialists in engineering, social and environmental sciences and environmental emergencies, to develop the environmental and social rehabilitation actions in all areas impacted along the River Doce. BHP Billiton, Vale and Samarco have jointly commissioned an external investigation into the cause of the dam failure. BHP Billiton has committed to publicly release the findings of the investigation, and to sharing the results with other resources companies. Discussions with the national government of Brazil and the state governments of Minas Gerais and Espírito Santo, aimed at reaching agreement for managing and funding long-term environmental and socio-economic rehabilitation plans, are ongoing. Asset quality and robust operating performance provide resilience in a challenging environment BHP Billiton delivered Underlying EBITDA of US$6.0 billion and an Underlying EBITDA margin of 40 per cent in the December 2015 half year, despite significantly weaker prices across all our major commodities which had a negative impact of US$7.8 billion. An unfavourable change in productivity of US$169 million(6) was recorded in the period due to the expected 25 per cent grade decline at Escondida. Excluding this impact, productivity increased by US$472 million. Further improvements continue to be realised across the portfolio and we expect to deliver approximately US$600 million of productivity gains in the 2016 financial year. Excluding the impact of grade decline at Escondida, we expect gains of approximately US$2.1 billion. During the period, Black Hawk drilling costs per well declined by 30 per cent, and Western Australia Iron Ore (WAIO) and Queensland Coal unit cash costs declined by 25 per cent and 17 per cent, respectively. Grade-adjusted unit cash costs at Escondida remained broadly unchanged despite reduced recoveries from the processing of lower-grade inventory, the commissioning of the OGP1 concentrator and additional stacking of lower-grade material to sulphide heap leach. The inventory was drawn down to maximise cash flow and combined with other working capital initiatives, facilitated a substantial increase in cash flow. These factors offset a 12 per cent improvement in underlying net cash costs(7). As our focus on safe productivity continues we have maintained or lowered unit cost guidance at our major assets. Historical costs and guidance for the 2016 financial year are summarised in the following table: FY15 H1 FY16 Previous Current FY16e vs FY16(i) FY16(i) FY15 guidance guidance Black Hawk drilling cost per well (US$ million) 3.4 2.6 2.5 2.3 (32%) Escondida unit cost (US$ per pound)(ii) 1.01 1.45 1.21 1.21 20% Escondida grade-adjusted unit cost (US$ per pound)(ii) 1.01 1.02 0.87 0.87 (14%) Western Australia Iron Ore unit cost (US$ per tonne) 19 15 15 15 (20%) Queensland Coal unit cost (US$ per tonne) 65 59 61 59 (9%) (i) Current 2016 financial year guidance is based on exchange rates of AUD/USD 0.72 and USD/CLP 702. Previous guidance was based on exchange rates of AUD/USD 0.74 and USD/CLP 702. (ii) Previous guidance presented at the Copper briefing and site tour in December 2015. Grade-adjusted unit cost guidance is presented on a grade-equivalent basis relative to the 2015 financial year. Grades are expected to decline by 27 per cent in the 2016 financial year. The Group reported Underlying attributable profit of US$412 million, while the Attributable loss of US$5.7 billion includes US$6.1 billion of exceptional items (after tax) related to: an impairment charge of US$4.9 billion against the carrying value of the Onshore US assets; US$858 million for the financial impacts of the Samarco dam failure on the Group’s income statement; and US$390 million for global taxation matters. 3

News Release Capital and exploration expenditure declined to US$3.6 billion, down 40 per cent, as we continued to exercise the flexibility in our investment program in response to market conditions. Other factors include improved capital productivity and the benefits of a stronger US dollar. Combined with a robust operating performance and a targeted reduction of working capital, the Group delivered free cash flow of US$1.2 billion during the period. Despite the significant weakening of commodity prices, we maintained our strong balance sheet, finishing the period with net debt of US$25.9 billion (30 June 2015: US$24.4 billion; 31 December 2014: US$24.9 billion) and a gearing ratio(2) of 29.7 per cent (30 June 2015: 25.7 per cent; 31 December 2014: 22.4 per cent). Enhancing our capital allocation framework to maximise shareholder value Since the merger of BHP and Billiton in 2001, our capital management framework has served our shareholders well. We maintained a strong balance sheet and returned US$77 billion in dividends and buy-backs to shareholders. In response to the increase in demand over the period, we invested in our tier 1 assets and infrastructure, doubling volumes and providing valuable options for future development. As a low-cost producer, this was the value-maximising strategy which underpinned superior margins and substantial cash flow generation. Several years ago, in anticipation of slowing demand growth and the abundance of potential new low-cost supply, we shifted our focus to reducing costs and debottlenecking our operations. Since 2012, we have embedded annualised productivity gains of more than US$10 billion(6) and reduced capital and exploration expenditure by over 50 per cent. Through the divestment of US$7 billion of assets and the demerger of South32, we have focused our portfolio on a small group of large, low-cost, long-life assets. While we were prepared for lower prices across our commodities, the reduction over the last six months has been more severe and synchronised than expected. The short to medium-term outlook for the sector remains challenging. We expect prices will take time to recover and are likely to remain volatile, however this environment should provide opportunities. We enter this downturn from a position of strength, with the simplest portfolio of high-quality assets, sector-leading operating capabilities, rising capital flexibility as current projects are completed and a strong balance sheet. Our strong balance sheet remains a fundamental enabler of our strategy. It provides access to sufficient, low-cost funding at all points in the cycle which provides optionality and insulates our operations from rising volatility. Our strength is demonstrated by our solid cash flow to net debt metrics (reflected in our credit ratings), liquidity of US$17 billion, moderate gearing and long-dated debt maturity profile. Today, we continue to implement measures to both preserve the Group’s balance sheet strength and align our capital allocation framework with the cyclical nature of the industry. Our priorities for capital are to: • first, maintain safe and stable operations; • second, maintain a strong balance sheet through the cycle; • third, pay shareholders a minimum of 50 per cent of Underlying attributable profit as dividends; and • fourth, direct remaining cash to the value-maximising outcome, with debt reduction, investing in growth projects, buying back shares, paying additional dividends and acquiring assets, all competing for capital. This framework provides valuable flexibility. This flexibility will support greater value creation for shareholders as it enhances our ability to maintain a strong balance sheet and invest counter cyclically at the bottom of the cycle, and embeds increased cash returns to shareholders at the top. The adoption of a 50 per cent dividend payout ratio will re-phase distributions to shareholders and while this payout level is in line with the average cash returned to shareholders since the merger, dividends will be more closely linked to the performance of our business. We remain strongly committed to cash returns to shareholders. At every reporting period, the Board will consider cash returns in excess of the minimum implied by the payout ratio, in accordance with the framework outlined above. 4

BHP Billiton Results for the half year ended 31 December 2015 Today, the Board has determined to pay an interim dividend of 16 US cents per share, a level covered by the Group’s free cash flow. This comprises the minimum payout of four US cents per share and an additional amount of 12 US cents per share, reflecting differences between Underlying attributable profit and free cash flow during the period. Strongly positioned for the future The Group’s rising capital productivity and latent capacity opportunities, cost deflation and a stronger US dollar mean that we do not require the same level of investment to grow as in the past. Reflecting this, and the flexibility of our Onshore US investment plans, we now expect our capital and exploration expenditure to be US$7.0 billion in the 2016 financial year and US$5.0 billion in the 2017 financial year. While this represents a total reduction of US$3.5 billion from previous guidance, the only reduction in activity is at Onshore US where we continue to respond to current market conditions. Our most valuable growth will come from operating more efficiently. This will be supported in the short to medium term by the release of latent capacity across the portfolio which should deliver growth in volumes and free cash flow at low capital intensity. In the medium to long term, we have a portfolio of development options which we can execute when the timing is right and it is determined to be the value-maximising outcome. We offer a unique proposition within the sector. We believe we have: • the simplest portfolio of large, low-cost, long-life assets diversified across a set of favoured commodities; • sector-leading operating capabilities; • the sector’s strongest balance sheet, supported at all points in the cycle by a more flexible dividend and investment program; • a portfolio of value-enhancing growth options; and • a transparent capital allocation framework to direct excess cash to the value-maximising outcome. While the sector faces challenges in the short to medium term, we remain confident in the long-term outlook which is supported by the ongoing urbanisation and industrialisation of emerging economies coupled with growing supply-side challenges, particularly in copper and oil. With rising volatility, the strength of our unique portfolio positions us to take advantage of market conditions through the cycle. Outlook Economic outlook Global growth is expected to pick up slightly in the 2016 calendar year but will remain modest and subject to ongoing financial markets volatility. Major developed economies should continue to recover mildly while emerging markets will see divergent levels of growth. Solid growth in India and parts of emerging Asia and Europe will be partially offset by ongoing weakness in Latin America and Russia. China will experience slower overall growth, and the divergence in sectoral performance is expected to persist with relatively soft industrial activity offset by a solid contribution from the services sector. This pattern reflects what appears to be a faster than expected transition away from reliance on investment, particularly in heavy industry, which is constraining commodity demand growth in the near term. Volatility will continue in the short-term as cautious economic reform evolves, particularly in the financial sector. With Chinese authorities appearing to increase their focus on “supply-side reform”, including State-Owned Enterprises, we expect some capacity reduction as industry consolidates over time. Over the longer term, economic reform and ongoing urbanisation will help to offset the impact of a declining workforce as growth converges to levels similar to developed economies. 5

News Release The US economy should see a mild lift in growth driven by consumer demand, supported by low energy prices and an improving housing market. The extent of interest rate increases in the United States in the 2016 calendar year will depend on the pace of economic growth and inflation. The Eurozone will likely see modest growth continue, supported by a lower Euro and stimulatory monetary policy. In Japan, better wages growth, increased business investment and a lower Yen should support mild economic improvement, though growth remains fragile. India’s economy will continue to grow solidly supported by infrastructure spend and lower commodity prices. In the longer term, growth will be sustained by rising domestic consumption and successful reform. Commodities outlook The crude oil price fell significantly in the first half of the 2016 financial year as supply continued to outpace demand following the disruption of OPEC and stronger than anticipated non-OPEC production. In the short term, we expect prices to remain weak as high inventory levels weigh on an oversupplied market and rising OPEC exports offset production declines in the United States. We expect the market will then rebalance as declining investment leads to a slowdown in non-OPEC supply growth while increasing demand draws down stocks. The long-term outlook remains healthy and is underpinned by rising transport sector demand in developing countries, natural field decline and deferrals of investment. The domestic gas price in the United States declined due to the ongoing over-supply and mild early-winter weather. Despite strong demand growth from the power sector, high gas storage levels are likely to keep prices subdued in the short term. In the longer term, demand is expected to benefit from LNG exports, further growth in gas power generation and increasing industrial use. As core gas reserves are depleted, less productive and higher-cost shale areas will be required to meet growing demand, supporting prices. In LNG, weaker fundamentals and low oil prices have impacted the spot market while longer-run demand growth remains healthy. Copper prices continued to be affected by growing supply, slightly weaker than expected demand, improved productivity at existing operations and a stronger US dollar. In the short to medium term, new and expanded production is expected to keep the market well supplied, despite cuts being announced to higher-cost production. In the long term, the copper outlook remains positive as demand is supported by China’s shift towards consumption and the scope for substantial growth in emerging markets. A deficit is expected to emerge towards the end of this decade as grade decline, rising costs and limited high-quality development opportunities constrain the industry’s ability to meet growing demand. Our outlook for Chinese crude steel production remains unchanged, peaking between 935 Mt and 985 Mt in the middle of the next decade, as China continues to urbanise and mature its manufacturing capability. In the short term, Chinese steel demand is expected to remain soft, with modest potential improvement if construction and infrastructure activity ramp-up in the first half of the 2016 calendar year. The iron ore price will likely remain low, constrained by weak demand and abundant seaborne iron ore supply. Over time, additional low-cost seaborne supply will continue to displace higher-cost supply, and we expect productivity gains will continue to be an industry feature. These factors point to a prolonged period of market rebalancing. In metallurgical coal, industry-wide supplier cost compression is expected to persist through the 2016 calendar year, with recent devaluations in China’s currency highlighting a key uncertainty for seaborne demand as imports become relatively more expensive. While high-cost seaborne supply will continue to rationalise, we expect further growth in low-cost, premium hard coking coal supply to offset production cuts and constrain potential for near-term price recovery. In the long term, we expect emerging markets such as India to support seaborne demand growth, while high-quality metallurgical coals will continue to offer steel makers value-in-use benefits to their operations. 6

BHP Billiton Results for the half year ended 31 December 2015 Petroleum Underlying EBIT for Petroleum decreased by US$2.5 billion to US$(235) million in the December 2015 half year.

(iii) Other includes: exchange rates; inflation; asset sales; ceased and sold operations; other items. Other items includes Onshore US rig termination charges of US$65 million (2014: US$13 million). Total petroleum production for the December 2015 half year decreased by five per cent to 124.7 MMboe. • Liquids production decreased by three per cent to 60.5 MMboe as higher Onshore US liquids volumes were more than offset by lower Conventional liquids production due to industrial action at Bass Strait and natural field decline across the portfolio. • Natural gas production declined by seven per cent to 386 bcf as lower Onshore US gas volumes were partially offset by higher seasonal demand at Bass Strait. Total petroleum production guidance for the 2016 financial year remains unchanged at 237 MMboe. • Strong performance by our Conventional business is expected to offset lower Onshore US volumes following a further reduction in development activity, a third party gas plant outage in the Permian and the successful divestment of our gas business in Pakistan. Depreciation and impairment charges, excluding exceptional items, declined in the December 2015 half year as a result of US$328 million of impairment charges incurred in the previous period. This was partially offset by US$210 million of higher depreciation and amortisation charges in Onshore US due to a reduction in total reserves, primarily at Fayetteville and Hawkville due to acreage relinquishments and amended development plans. Depreciation and amortisation charges are expected to decline by approximately US$450 million in the second half of the 2016 financial year following an impairment charge of US$7.2 billion against the carrying value of the Onshore US assets in the December 2015 half year. Petroleum capital expenditure declined by 44 per cent to US$1.5 billion in the December 2015 half year. This included US$851 million of Onshore US drilling and development expenditure. We realised further improvements in shale drilling and completions efficiency during the period as our drill time and completion techniques showed marked improvement in the Black Hawk and Permian. We now expect to reduce Black Hawk drilling costs further to US$2.3 million per well in the 2016 financial year. Cost per well (US$M) H1 FY16 H2 FY15 H1 FY15 FY15 Black Hawk: Drilling cost 2.6 2.9 3.7 3.4 Black Hawk: Completion cost 3.2 4.2 5.4 4.9 Permian: Drilling cost 3.9 4.3 4.8 4.6 Permian: Completion cost 3.1 4.3 4.9 4.6 Petroleum capital expenditure of approximately US$2.7 billion is now planned in the 2016 financial year, a seven per cent decline from prior guidance of US$2.9 billion. This includes Conventional capital expenditure of US$1.4 billion, which remains focused on high-return infill drilling opportunities in the Gulf of Mexico and life extension projects at Bass Strait and North West Shelf, and Onshore US capital expenditure of US$1.3 billion, of which approximately US$200 million relates to a reduction in capital creditors. 13

News Release Our Onshore US operated rig count has now reduced from seven to five as we defer development activity to preserve value. Completions activity will continue to be tailored to market conditions and we will exercise further flexibility should there be greater value in deferral. We have continued confidence in the quality of our Onshore US acreage, and our track record in operating performance and capital productivity is among the best in the industry. While we are focused on value and cash flow preservation as we manage through this period of lower prices, we retain the option to develop our resources as prices recover to maximise the value of these quality assets.

Petroleum exploration expenditure for the December 2015 half year was US$321 million, of which US$126 million was expensed. Activity for the period was largely focused in the deepwater Gulf of Mexico, the Caribbean and the Beagle sub-basin off the coast of Western Australia. We are pursuing high-quality oil plays in these three focus areas and continue to invest opportunistically in future growth options. Since August 2015, BHP Billiton has acquired 26 blocks in the Western Gulf of Mexico Lease Sale with a 100 per cent working interest. A US$600 million exploration program remains on plan for the 2016 financial year, largely focused on acreage access, seismic data acquisition and increased activity in our exploration drilling program. 14

BHP Billiton Results for the half year ended 31 December 2015 Copper Underlying EBIT for the December 2015 half year decreased by US$1.9 billion to US$101 million.

(ii) Includes drawdown of higher-cost inventory built up in prior periods and write-downs, predominantly at Escondida, of US$578 million. (iii) Other includes: fuel and energy; asset sales; other items (including profit from equity accounted investments). Total copper production for the December 2015 half year decreased by six per cent to 762 kt. Escondida copper production decreased 18 per cent to 452 kt as record material mined, underpinned by improvements in truck availability and utilisation, was more than offset by a 25 per cent decline in grade. Pampa Norte copper production was broadly unchanged at 126 kt as record ore milled and higher grade underpinned record production at Spence and offset lower recoveries at Cerro Colorado. Olympic Dam copper production increased by 37 per cent to a record 112 kt and reflects record ore milled and improved smelter utilisation following planned maintenance in the prior period. Antamina copper production increased by 36 per cent to 72 kt as higher grades and recoveries were supported by record material mined and milled. Total copper production guidance for the 2016 financial year remains unchanged at 1.5 Mt. Guidance for Escondida remains unchanged at 940 kt. Pampa Norte production is now expected to be ahead of the prior year. Olympic Dam production is now expected to exceed 200 kt. Guidance for Antamina remains unchanged at 136 kt. The ramp-up of the Escondida Organic Growth Project 1 (OGP1) progresses ahead of plan and is expected to reach full capacity during the 2016 financial year. In the medium term, completion of the Escondida Water Supply project and the potential life extension of the Los Colorados concentrator will enable utilisation of three concentrators to offset grade decline and support a strong recovery in production(9). In the short to medium term, the Spence Recovery Optimisation project should enable the full utilisation of approximately 200 ktpa of tankhouse capacity. Unit cash costs at our operated copper assets declined by eight per cent to US$1.11 per pound on an Escondida grade-adjusted basis during the December 2015 half year. This reflects the benefit of productivity-led cost improvements and a further reduction in labour and contractor costs, particularly at Olympic Dam where unit costs declined by 36 per cent. 17

News Release Escondida’s Underlying EBIT declined by US$1.7 billion in the December 2015 half year and reflected lower realised prices and expected grade-related volume decline. This reduction also included inventory movements and write-downs of US$448 million. The inventory movements reflect a build of lower-grade inventory in prior periods in line with the optimised mine plan, followed by a partial drawdown in the December 2015 half year. The use of lower-grade stockpiled inventory resulted in lower recoveries, which have subsequently returned to normal levels, but provided a substantial reduction of working capital and increased cash flow during the period. Robust production performance and benefits from the Escondida 3.0 productivity program supported grade-adjusted unit costs which remained broadly unchanged at US$1.02 per pound in the December 2015 half year. Excluding the impact of inventory movements, net cash costs declined 12 per cent. Escondida’s grade-adjusted unit cost guidance remains unchanged at US$0.87 per pound(10) for the 2016 financial year. We expect a strong recovery of concentrate production in the second half of the 2016 financial year supported by higher throughput from the continued ramp-up of OGP1 and improved recoveries and water availability. We also expect a reduction in the average unit cost of cathode production due to sulphide leach productivity initiatives, which include increasing the area of stacked material under irrigation, encompassing older zones of the pad. These initiatives will result in a decline in the average cost of sulphide leach inventory in the second half of the 2016 financial year. In addition, the use of lower-grade ore stocks will support a 45 per cent increase in material stacked over the period to maintain optimal cathode production in the 2017 and 2018 financial years.

News Release Iron Ore Underlying EBIT for the December 2015 half year decreased by US$2.3 billion to US$1.9 billion. US$M Underlying EBIT for the half year ended 31 December 2014 4,200 Net price impact(i) (2,828) Change in volumes: productivity 175 Change in controllable cash costs 146 Change in other costs: Exchange rates 278 Inflation (32) Other(ii) (12) Underlying EBIT for the half year ended 31 December 2015 1,927 (i) Average realised price: iron ore US$43/wmt, FOB (2014: US$70/wmt, FOB). (ii) Other includes: fuel and energy; depreciation, deferred stripping and impairment; asset sales; other items. Other items includes net profit from the equity accounted investment in Samarco, but does not include any financial impacts following the Samarco dam failure which has been treated as an exceptional item. Total iron ore production for the December 2015 half year increased by four per cent to 118 Mt. Western Australia Iron Ore (WAIO) production increased by six per cent to a record 131 Mt (100 per cent basis), underpinned by the Jimblebar mining hub operating at full capacity and improved ore handling plant utilisation at Newman. Samarco production decreased by 25 per cent to 11 Mt (100 per cent basis). Mining and processing operations remain suspended following the dam failure. The final shipment of pellets from port stockpiles is expected to be completed in the March 2016 quarter. Total iron ore production for the 2016 financial year of 237 Mt is expected, four per cent lower than prior guidance. Revision of total iron ore guidance reflects the suspension of operations at Samarco. WAIO guidance remains unchanged at 270 Mt (100 per cent basis). However, following unfavourable weather conditions in January we will continue to monitor progress against guidance and will provide an update in the March 2016 operational review if required. Work has commenced on the installation of a new primary crusher and additional conveying capacity at Jimblebar. Associated costs are included within WAIO’s average annual sustaining capital expenditure which is now expected to be approximately US$4 per tonne following continued improvements in capital productivity. The ramp-up of additional capacity at the Jimblebar mining hub along with further productivity improvements, will deliver an increase in system capacity to 290 Mtpa over time. WAIO unit cash costs declined by 25 per cent to US$15.21 per tonne, underpinned by a stronger US dollar, reductions in labour and contractor costs, and lower diesel prices and consumption. Unit cost guidance for the 2016 financial year remains unchanged at US$15 per tonne(10).

(ii) One-off items reflect royalty and taxation matters. (iii) Other includes: fuel and energy; asset sales; ceased and sold operations; other items (including loss from equity accounted investments). Metallurgical and energy coal production both declined by three per cent, to 21 Mt and 19 Mt respectively, in the December 2015 half year. Record metallurgical coal production at four Queensland Coal mines was offset by a convergence event at the Broadmeadow mine and completion of longwall mining at the low-cost Crinum mine. First metallurgical coal production from the Haju mine in Indonesia was achieved. Drought conditions at Cerrejón and heavy rainfall and blasting constraints at New South Wales Energy Coal reduced energy coal production. Metallurgical coal production guidance for the 2016 financial year remains unchanged at 40 Mt. Energy coal production for the 2016 financial year is now expected to be 37 Mt following completion of the sale of the San Juan Mine to Westmoreland Coal Company on 31 January 2016. Queensland Coal unit cash costs declined by 17 per cent to US$59 per tonne, as the operations benefited from a stronger US dollar, lower diesel prices and a reduction in labour and contractor costs reflecting continued productivity improvements. This offset inventory write-downs due to weaker coal prices, the impact of a convergence event at the Broadmeadow mine, a higher than usual number of planned maintenance shutdowns, and costs associated with the closure of the Crinum mine as it reached the end of its economic reserve life. Unit costs for the 2016 financial year are now expected to be US$59 per tonne(10), as favourable currency movements offset the removal of low-cost Crinum volumes.

News Release Group and unallocated items Underlying EBIT expense decreased by US$157 million to US$145 million in the December 2015 half year. The reduction reflected transaction costs associated with the successful demerger of South32 incurred in the prior period, the favourable exchange rate impact on Nickel West costs, and lower corporate overheads. This more than offset lower average realised prices received by Nickel West. Resources and reserves assessment Samarco is reviewing the operation’s resources and reserves following the dam failure. BHP Billiton is continuing to work closely with Samarco and we expect to provide updated information as soon as we are in a position to do so. 24

Financial Report Notes to the Financial Information 1. Accounting policies This general purpose financial report for the half year ended 31 December 2015 is unaudited and has been prepared in accordance with IAS 34 “Interim Financial Reporting” as issued by the International Accounting Standards Board (IASB), IAS 34 “Interim Financial Reporting” as adopted by the EU, AASB 134 “Interim Financial Reporting” as issued by the Australian Accounting Standards Board (AASB) and the Disclosure and Transparency Rules of the Financial Conduct Authority in the United Kingdom and the Australian Corporations Act 2001 as applicable to interim financial reporting. The half year financial statements represent a “condensed set of financial statements” as referred to in the UK Disclosure and Transparency Rules issued by the Financial Conduct Authority. Accordingly, they do not include all of the information required for a full annual report and are to be read in conjunction with the most recent annual financial report. The comparative figures for the financial year ended 30 June 2015 are not the statutory accounts of the BHP Billiton Group for that financial year. Those accounts, which were prepared under IFRS, have been reported on by the Company’s auditor and delivered to the registrar of companies. The auditor has reported on those accounts; the report was unqualified, did not include a reference to any matters to which the auditors drew attention by way of emphasis without qualifying their report and did not contain statements under Section 498 (2) or (3) of the UK Companies Act 2006. The half year financial statements have been prepared on the basis of the accounting policies and methods of computation consistent with those applied in the 30 June 2015 annual financial statements contained within the Annual Report of the BHP Billiton Group. Rounding of amounts Amounts in this financial report have, unless otherwise indicated, been rounded to the nearest million dollars. Comparatives Where applicable, comparative periods have been adjusted to disclose them on the same basis as the current period figures. The 31 December 2014 financial information has been restated for the effects of the application of IFRS 5/AASB 5 ‘Non-current Assets Held for Sale and Discontinued Operations’ following the demerger of South32 in May 2015. The nature of each change reflected in the restated financial information is as follows: • All income and expense items relating to South32 have been removed from the individual line items in the Consolidated Income Statement. The post-tax (loss)/profit of South32 is presented as a single amount in the line item entitled “(Loss)/Profit after taxation from discontinued operations”; and • All cash flows and other items relating to South32 have been removed from the individual line items in the Consolidated Cash Flow Statement. The net cash flows attributable to the operating, investing and financing activities of South32 and the cash disposed of on demerger of South32 are each disclosed in single amount in each section of the Consolidated Cash Flow Statement. The Consolidated Balance Sheet, the Consolidated Statement of Comprehensive Income and the Consolidated Statement of Changes in Equity for these periods are not required to be restated. 36

BHP Billiton Results for the half year ended 31 December 2015 8. Financial risk management – Fair values All financial assets and financial liabilities, other than derivatives, are initially recognised at the fair value of consideration paid or received, net of transaction costs as appropriate, and subsequently carried at fair value or amortised cost, as indicated in the tables below. Derivatives are initially recognised at fair value on the date the contract is entered into and are subsequently remeasured at their fair value. The financial assets and liabilities are presented by class in the tables below at their carrying values, which generally approximate to fair value. In the case of US$3,320 million (30 June 2015: US$3,321 million) of fixed rate debt not swapped to floating rate, the fair value at 31 December 2015 was US$3,148 million (30 June 2015: US$3,538 million).

BHP Billiton Results for the half year ended 31 December 2015 8. Financial Risk Management – Fair values (continued) Fair value hierarchy The carrying amount of financial assets and liabilities measured at fair value is where possible, calculated with reference to quoted prices in active markets for identical assets or liabilities. Where no price information is available from a quoted market source, alternative market mechanisms or recent comparable transactions, fair value is estimated based on the Group’s views on relevant future prices, net of valuation allowances to accommodate liquidity, modelling and other risks implicit in such estimates. The inputs used in fair value calculations are determined by the relevant Group Function. Our Group Functions support the Businesses and operate under a defined set of accountabilities authorised by the Group Management Committee (GMC). Movements in the fair value of financial assets and liabilities may be recognised through the income statement or in other comprehensive income. The following table shows the Group’s financial assets and liabilities carried at fair value with reference to the nature of valuation inputs used. 31 December 2015 Level 1(a) US$M Level 2(b) US$M Level 3(c) US$M Total US$M Financial assets and liabilities Trade and other receivables – 682 – 682 Trade and other payables – (376) – (376) Cross currency and interest rate swaps – (978) – (978) Commodity contracts – (4) – (4) Other derivative contracts – (5) 305 300 Investments(d) 55 – 18 73 Total 55 (681) 323 (303) 30 June 2015 Level 1(a) US$M Level 2(b) US$M Level 3(c) US$M Total US$M Financial assets and liabilities Trade and other receivables – 952 – 952 Trade and other payables – (176) – (176) Cross currency and interest rate swaps – (275) – (275) Forward exchange contracts – 1 – 1 Commodity contracts – 2 – 2 Other derivative contracts – 12 198 210 Investments(d) 1 – 21 22 Total 1 516 219 736 (a) Valuation is based on unadjusted quoted prices in active markets for identical financial assets and liabilities.

Sensitivity of level 3 financial assets and liabilities The carrying amount of financial assets and liabilities that are valued using inputs other than observable market data are calculated using appropriate valuation models, including discounted cash flow modelling, with inputs such as commodity prices, foreign exchange rates and inflation. The potential effect of using reasonably possible alternative assumptions in these models, based on a change in the most significant input by 10 per cent while holding all other variables constant, is shown in the following table. Significant inputs are assessed individually for each financial asset and liability.

BHP Billiton Results for the half year ended 31 December 2015 9. Significant events – Samarco dam failure On 5 November 2015, the Samarco Mineração S.A (Samarco) iron ore operation in Minas Gerais, Brazil experienced a tailings dam failure that resulted in a release of mine tailings, flooding the community of Bento Rodrigues and impacting other communities downstream (the Samarco dam failure). Refer to pages 2 and 3 for further details. Samarco is jointly owned by BHP Billiton Brasil Limitada (BHP Billiton Brasil) and Vale S.A (Vale). BHP Billiton Brasil’s 50% interest is accounted for as an equity accounted joint venture investment. BHP Billiton Brasil does not separately recognise its share of the underlying assets and liabilities of Samarco, but instead records the investment as one line on the balance sheet. Accordingly, for any charges recognised by Samarco, BHP Billiton Brasil and therefore the Group recognise 50% of this expense when adjusting the carrying value of the investment for the BHP Billiton share of Samarco’s profit or loss. Any charges incurred directly by BHP Billiton Brasil or other BHP Billiton entities are recognised 100% in the Group’s results. The financial impacts of the Samarco dam failure on the Group’s income statement, balance sheet and cash flow statement for the half year ended 31 December 2015 are shown in the table below and have been treated as an exceptional item. These do not include BHP Billiton Brasil’s share of the results of Samarco prior to the Samarco dam failure, which is disclosed in the note 4 Interests in associates and joint venture entities.

Financial Report 9. Significant events – Samarco dam failure (continued) Equity accounted investment in Samarco The following table details the movement in the carrying value of BHP Billiton Brasil’s equity accounted investment in Samarco: Half year ended 31 December 2015 US$M At the beginning of the reporting period 1,044 Share of operating profit prior to the Samarco dam failure 136 Share of loss relating to the Samarco dam failure (655) Impairment of the carrying value of the investment in Samarco (525) (Loss)/profit from equity accounted investments and related impairments (1,044) Investment — Dividends received — At the end of the reporting period — Subsequent to recognising the Group’s share of Samarco’s loss, the Group has assessed the recoverability of its investment in light of uncertainties surrounding the nature and timing of ongoing future operations. As a result, an impairment charge of US$525 million was recognised in the half year ended 31 December 2015. Funding Under the terms of the joint venture agreement, BHP Billiton Brasil does not have an existing obligation to fund Samarco. To date, no requests for funding or future investment have been received. Any future investment would be subject to a future decision and be accounted for at that time. Contingencies BHP Billiton Brasil contingencies As at 31 December 2015 BHP Billiton Brasil has identified contingent liabilities arising as a consequence of the Samarco dam failure as follows: Environment and socio-economic rehabilitation Rio Doce Fund On Friday 27 November 2015, BHP Billiton and Vale announced plans to work, together with Samarco, to establish a voluntary, non-profit fund to support the recuperation of the Rio Doce river system, affected by the Samarco dam failure. Until such time as BHP Billiton and Vale determine the extent of the commitment to this voluntary fund, it is not possible to arrive at a range of outcomes or a reliable estimate of the commitment and therefore a provision has not been recognised and nor has any contingent liability been quantified. Legal BHP Billiton Brasil is among the companies named as defendants in legal proceedings initiated by individuals, non-governmental organisations (NGOs), corporations and governmental entities in Brazilian federal and state courts following the Samarco dam failure. The other defendants include Vale S.A. and Samarco. The lawsuits include claims for compensation, environmental rehabilitation and violations of Brazilian environmental and other laws, among other matters. The lawsuits seek various remedies, including rehabilitation costs, compensation to injured individuals and families of the deceased, recovery of personal and property losses and injunctive relief. In addition, government inquiries and investigations relating to the Samarco dam failure have been commenced by numerous agencies of the Brazilian government. 48

BHP Billiton Results for the half year ended 31 December 2015 9. Significant events – Samarco dam failure (continued) Among the claims brought against BHP Billiton Brasil, is a Public Civil Claim commenced by the Federal Attorney General, States of Espirito Santo, Minas Gerais and other public authorities on 30 November 2015, seeking the establishment of a fund of up to R$20 billion (US$5.1 billion) in aggregate for clean-up costs and damages. BHP Billiton Brasil, Samarco and Vale S.A. are currently in negotiations with the Brazilian government in relation to this claim. Given the preliminary status of these negotiations, it is not possible at this time to provide a range of possible outcomes or a reliable estimate of potential future exposures for BHP Billiton Brasil in relation to the R$20 billion (US$5.1 billion) claim. Additional lawsuits and government investigations relating to the Samarco dam failure may be brought against BHP Billiton Brasil and possibly other BHP Billiton entities in Brazil or other jurisdictions. BHP Billiton’s potential liabilities resulting from other pending and future claims, lawsuits and enforcement actions relating to the Samarco dam failure, together with the potential cost of implementing remedies sought in the various proceedings, cannot be reliably estimated at this time and therefore a provision has not been recognised and nor has any contingent liability been quantified. Ultimately these could have a material adverse impact on BHP Billiton’s business, competitive position, cash flows, prospects, liquidity and shareholder returns. Samarco contingencies Environment and socio-economic rehabilitation As at 31 December 2015, Samarco has recognised provisions based on currently available information. Samarco has indicated that it anticipates that it will incur future costs beyond those provisioned. The magnitude, scope and timing of costs related to the Samarco dam failure are subject to a very high degree of uncertainty, primarily due to immaturity of the environmental and socio-economic impact assessments, as well as approval of rehabilitation scope and ongoing activities of regulators and other government authorities. These uncertainties are likely to continue for a significant period. Any such unrecognised obligations are therefore contingent liabilities and, at present, it is not practicable to estimate their magnitude or possible timing of payment. Accordingly, it is also not possible to provide a range of possible outcomes or a reliable estimate of total potential future exposures at this time. As the assessment of damage progresses, changes to key assumptions could result in a material change to the amount of the provision in future reporting periods. Legal Samarco has been named as a defendant in numerous lawsuits resulting from the Samarco dam failure. These lawsuits have been brought by individuals, corporations, NGOs and governmental entities seeking damages for, among other matters, personal injury, wrongful death, commercial or economic injury, breach of contract and violations of statutes. In addition, government investigations of the Samarco dam failure by numerous agencies of the Brazilian government have commenced. As noted above, amongst the claims brought against Samarco is a Public Civil Claim commenced by the Federal Attorney General, States of Espirito Santo, Minas Gerais and other public authorities on 30 November 2015, seeking the establishment of a fund of up to R$20 billion (US$5.1 billion) in aggregate for clean-up costs and damages. BHP Billiton Brasil, Samarco and Vale S.A. are currently in negotiations with the Brazilian government in relation to this claim. Given the preliminary status of these negotiations, it is not possible at this time to provide a range of possible outcomes or a reliable estimate of potential future exposures for Samarco in relation to the R$20 billion (US$5.1 billion) claim. Other pending lawsuits and investigations are at the early stages of proceedings. 49

Financial Report 9. Significant events – Samarco dam failure (continued) Until further facts are developed; court rulings clarify the issues in dispute, liability and damages; trial activity nears, or other actions such as possible settlements occur, it is not possible to arrive at a range of outcomes or a reliable estimate of Samarco’s obligations arising from these matters and therefore Samarco has not recognised a provision or quantified a contingent liability. Additional claims may be brought against Samarco. A provision has not been made by Samarco for claims yet to be filed. Given the significant uncertainties surrounding possible outcomes it is not possible for Samarco to arrive at a range of outcomes or a reliable estimate of the liability for any unfiled claims. Insurance BHP Billiton Insurance BHP Billiton has third party liability insurance for claims related to the Samarco dam failure made directly against BHP Billiton Brasil or other BHP Billiton entities. Such claims may be externally insured up to US$360 million (when adjusted for BHP Billiton Brasil’s interest in Samarco). External insurers have been advised of the Samarco dam failure although no formal claim has currently been made under the policy. At 31 December 2015 an insurance receivable has not been recognised for any potential recoveries under insurance arrangements. Samarco Insurance Samarco has standalone insurance policies in place with Brazilian and global insurers. Samarco has notified insurers including those covering property, project and liability risks. Insurers have appointed loss adjusters or claims representatives to investigate and assist with the claims process. Given the adjustment process for all policies is at an early stage with the extent of coverage yet to be agreed, an insurance receivable has not been recognised by Samarco for any recoveries under insurance arrangements at 31 December 2015. 10. Subsequent events Other than the matters outlined elsewhere in this financial information, no matters or circumstances have arisen since the end of the half year that have significantly affected, or may significantly affect, the operations, results of operations or state of affairs of the Group in subsequent accounting periods. 50

We have reviewed the condensed half year financial statements of the Group for the half year ended 31 December 2015 (“half year financial statements”), set out on pages 29 to 50, which comprise the consolidated income statement, consolidated statement of comprehensive income, consolidated balance sheet, consolidated cash flow statement, consolidated statement of changes in equity, summary of significant accounting policies and other explanatory notes 1 to 10. We have read the other information contained in the half year financial report and considered whether it contains any apparent misstatements or material inconsistencies with the information in the half year financial statements. KPMG Australia has also reviewed the directors’ declaration set out on page 53 in relation to Australian regulatory requirements contained in section (a) and (c) of the directors’ declaration. Directors’ Responsibilities The half year financial report is the responsibility of, and has been approved by, the Directors. The Directors are responsible for preparing the half year financial report: in accordance with the Disclosure and Transparency Rules (“the DTR”) of the United Kingdom’s Financial Conduct Authority (“the UK FCA”), and under those rules, in accordance with IAS 34 Interim Financial Reporting as adopted by the European Union; and in accordance with Australian Accounting Standards and the Corporations Act 2001. This responsibility includes establishing and maintaining internal control relevant to the preparation and fair presentation of the half year financial statements that are free from material misstatement, whether due to fraud or error; selecting and applying appropriate accounting policies; and making accounting estimates that are reasonable in the circumstances. Respective Responsibilities of KPMG UK and KPMG Australia KPMG UK’s report is made solely to BHP Billiton Plc in accordance with the terms of KPMG UK’s engagement to assist BHP Billiton Plc in meeting the requirements of the DTR of the UK FCA. KPMG UK’s review has been undertaken so that it might state to BHP Billiton Plc those matters it is required to state to it in this report and for no other purpose. To the fullest extent permitted by law, KPMG UK does not accept or assume responsibility to anyone other than BHP Billiton Plc, for KPMG UK’s review work, for this report, or for the conclusions it has reached. KPMG Australia has performed an independent review of the half year financial statements and directors’ declaration in order to state whether, on the basis of the procedures described, it has become aware of any matter that makes KPMG Australia believe that the half year financial statements and directors’ declaration are not in accordance with the Corporations Act 2001 including: giving a true and fair view of the Group’s financial position as at 31 December 2015 and its performance for the half year ended on that date; and complying with Australian Accounting Standard AASB 134 Interim Financial Reporting and the Australian Corporations Regulations 2001. Our responsibility is to express a conclusion on the half year financial statements in the half year financial report based on our review. Scope of Review KPMG UK conducted its review in accordance with International Standard on Review Engagements (UK and Ireland) 2410 Review of Interim Financial Information Performed by the Independent Auditor of the Entity issued by the Auditing Practices Board for use in the United Kingdom. 55

Financial Report KPMG Australia conducted its review in accordance with Auditing Standard on Review Engagements ASRE 2410 Review of a Financial Report Performed by the Independent Auditor of the Entity as issued by the Australian Auditing and Assurance Standards Board. As auditor of BHP Billiton Limited, KPMG Australia is required by ASRE 2410 to comply with the ethical requirements relevant to the audit of the annual financial report. A review of half year financial statements consists of making enquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with auditing standards and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion. Independence In conducting its review, KPMG Australia has complied with the independence requirements of the Australian Corporations Act 2001. Review conclusion by KPMG UK Based on our review, nothing has come to our attention that causes us to believe that the condensed half year financial statements in the half year financial report for the six months ended 31 December 2015 are not prepared, in all material respects, in accordance with IAS 34 Interim Financial Reporting, as adopted by the EU, and the DTR of the UK FCA. Stephen Oxley Partner For and on behalf of KPMG LLP Chartered Accountants London 23 February 2016 Review conclusion by KPMG Australia Based on our review, which is not an audit, we have not become aware of any matter that makes us believe that the condensed half year financial statements and directors’ declaration of the Group are not in accordance with the Australian Corporations Act 2001, including: a) giving a true and fair view of the Group’s financial position as at 31 December 2015 and of its performance for the half year ended on that date; and b) complying with Australian Accounting Standard AASB 134 Interim Financial Reporting and the Australian Corporations Regulations 2001.
