BHP OPERATIONAL REVIEW

FOR THE quarter ended 30 September 2017

   --    All production and unit cost guidance remains unchanged for the 2018 financial year. 

-- Good progress has been made on our latent capacity projects, with first production from the Los Colorados Extension project and the Olympic Dam Southern Mining Area achieved in the September 2017 quarter and the Caval Ridge Southern Circuit project progressing to plan.

   --    All major projects under development are tracking to plan. 

-- In Onshore US, our operated rig count increased from five to nine during the September 2017 quarter. Divestment of a small portion of the Hawkville acreage was completed during the quarter, with work underway to exit our remaining Onshore US assets for value.

-- In Petroleum exploration, evaluation of the positive drilling results from Wildling-2 is continuing, with a sidetrack also encountering oil in multiple horizons which will assist with establishing the scale of the discovery.

BHP Chief Executive Officer, Andrew Mackenzie, said: "Our performance in the first quarter keeps us on track to deliver seven per cent volume growth in the 2018 financial year.

We manage the portfolio for value and returns. Our transition to lower-cost, high-return, latent capacity projects is delivering results, with first copper production achieved from the Los Colorados Extension project at Escondida and Olympic Dam's Southern Mining Area during the quarter.

Major development work has commenced on the recently approved growth projects, Mad Dog Phase 2 and the Spence Growth Option, with both set to become operational as their respective markets in oil and copper rebalance."

Major development projects

On 17 August 2017, the BHP Board approved an investment of US$2.5 billion for the development of the Spence Growth Option.

At the end of the September 2017 quarter, BHP had four major projects under development in Petroleum, Copper and Potash, with a combined budget of US$7.5 billion over the life of the projects.

Corporate update

On 20 September 2017, BHP released its Economic Contribution Report which shows the Group's direct economic contribution globally in the 2017 financial year was US$26.1 billion. This includes US$4.7 billion in taxes, royalties and other payments to governments. BHP's adjusted effective tax rate in the 2017 financial year was 34.0 per cent. When royalties are included, the rate was 44.0 per cent. In Australia, we anticipate making final corporate income tax cash payments in the first half of the 2018 financial year of approximately US$1.2 billion relating to the prior year.

On 22 September 2017, BHP successfully concluded its US$2.9 billion multi-currency bond repurchase plan. The bond repurchase plan has extended BHP's average debt maturity profile and enhanced the Group's capital structure. The total cost in relation to the repurchase program was approximately US$100 million, which will be reported in net finance costs in the December 2017 half year. This does not take into account the multi-year interest expense saving from a lower average debt balance following the bond repurchase program.

Total petroleum production - Total petroleum production for the September 2017 quarter decreased by eight per cent to 50 MMboe. Guidance for the 2018 financial year remains unchanged at between 180 and 190 MMboe, comprising Conventional volumes between 119 and 123 MMboe and Onshore US volumes between 61 and 67 MMboe.

Crude oil, condensate and natural gas liquids - Crude oil, condensate and natural gas liquids production for the September 2017 quarter declined by nine per cent to 22 MMboe.

Conventional liquids volumes decreased by five per cent to 15 MMboe reflecting natural field decline across the portfolio, the impact of Hurricane Harvey in the Gulf of Mexico and planned maintenance at North West Shelf.

Onshore US liquids volumes decreased by 15 per cent to 7 MMboe as a result of natural field decline and the impact of Hurricane Harvey, which more than offset additional wells put online in the Black Hawk and Permian.

Natural gas - Natural gas production for the September 2017 quarter declined by seven per cent to 169 bcf.

Conventional gas volumes for the September 2017 quarter were broadly unchanged at 107 bcf. Onshore US gas volumes declined by 17 per cent reflecting natural field decline and the impact of Hurricane Harvey, partially offset by additional wells put online in the Black Hawk, Permian and Haynesville.

In the September 2017 quarter, we completed an agreement with Chevron and ExxonMobil to withdraw from our 4.95 per cent interest in the Genesis deepwater asset in the Gulf of Mexico, consistent with our aim to further simplify the portfolio. Financial closing is expected by the end of November 2017, with an effective date of 1 January 2017.

Petroleum capital expenditure of approximately US$2.0 billion is planned in the 2018 financial year. This includes Conventional capital expenditure of US$0.8 billion, which remains focused on high-return infill drilling opportunities in the Gulf of Mexico, a life extension project at North West Shelf and investment in the Mad Dog Phase 2 project. Onshore US capital expenditure is expected to be approximately US$1.2 billion reflecting increased development activity.

Onshore US development activity

Onshore US drilling and development expenditure for the September 2017 quarter was US$131 million. Our operated rig count increased from five to nine during the quarter as two rigs in the Permian, and one in each of the Black Hawk and Haynesville, were added.

-- In the Permian, we continued to drill to meet ongoing Hold by Production obligations while also progressing sub-surface trials intended to de-risk future development.

-- In the Black Hawk, we observed better than expected performance in recent trials which improved completion designs, enhanced staggered laterals and demonstrated commerciality of Upper and Lower Eagle Ford co-development.

-- In the Haynesville, our hedging strategy continues to allow us to reduce price risk and secure average rates of return in excess of 20 per cent.

-- In the Fayetteville, we continue to work with partners to assess the potential of the Moorefield horizon. We anticipate participation in additional non-operated wells in the 2018 financial year.

The Wildling-2 well was spud on 15 April 2017 and drilling was completed on 11 August 2017. The Wildling-2 well encountered oil in multiple horizons. A sidetrack to the Wildling-2 well commenced on 11 August 2017 to further appraise the discovery and was completed on 26 September 2017. This also encountered oil in multiple horizons and will assist further with establishing the scale of the discovery.

In the US Gulf of Mexico, the Scimitar well spud on 1 October 2017 with results expected in the March 2018 quarter. BHP holds a 65 per cent working interest and is the operator of the Scimitar prospect, with partner Repsol (20 per cent working interest) and Statoil (15 per cent working interest).

In Mexico, an Exploration and Appraisal plan for the Trion contractual area license number CNH-A1-Trion/2016 (formerly referred to as blocks AE-0092 and AE-0093) was submitted to the Comisión Nacional de Hidrocarburos of Mexico by BHP and Pemex on 29 August 2017, in line with regulatory requirements.

In Trinidad and Tobago, we continued appraisal work to assess the potential commercialisation of the gas discovery at LeClerc. Preparations continued for Phase 2 deepwater exploration which is expected to commence in the second half of the 2018 financial year.

Petroleum exploration expenditure for the September 2017 quarter was US$207 million, of which US$78 million was expensed. A US$715 million exploration program is planned for the 2018 financial year. This program includes the Scimitar exploration well in the US Gulf of Mexico and three wells in Trinidad and Tobago.

Copper - Total copper production for the September 2017 quarter increased by 14 per cent to 404 kt. Guidance for the 2018 financial year remains unchanged at between 1,655 and 1,790 kt.

Escondida copper production for the September 2017 quarter increased by 23 per cent to 268 kt, supported by the start-up of the Los Colorados Extension (LCE) project on 10 September 2017 and higher average copper grade and throughput. LCE is expected to ramp-up to full capacity during the December 2017 quarter, enabling utilisation of the three concentrators, and support copper production of between 1,130 and 1,230 kt in the 2018 financial year. Escondida and Union Ndeg2 of Supervisors and Staff signed a new Collective Agreement, valid from 1 October 2017, which will have a duration of 36 months. The existing agreement with Union Ndeg1 will expire on 1 August 2018.

Pampa Norte copper production for the September 2017 quarter decreased by seven per cent to 58 kt, despite record material mined at Cerro Colorado and record ore milled at Spence. The decrease was mainly due to unplanned maintenance at Spence's tank house during the quarter. Pampa Norte copper production for the 2018 financial year is expected to be higher than the prior year.

Olympic Dam copper production increased by three per cent to 42 kt with first ore achieved from the high-grade Southern Mining Area in the September 2017 quarter. Copper production of 150 kt is expected in the 2018 financial year as a major smelter maintenance campaign is undertaken. The maintenance campaign commenced on 21 August 2017 and will be phased through to the December 2017 quarter. On completion, improved operating performance, coupled with higher ore grades from the Southern Mining Area, will underpin an expected increase in production to approximately 215 kt in the 2019 financial year.

Antamina copper production for the September 2017 quarter increased by five per cent to 36 kt due to higher head grades. Copper production of approximately 125 kt is expected in the 2018 financial year as mining continues through a zinc-rich ore zone consistent with the mine plan. Zinc production of approximately 100 kt is expected for the 2018 financial year.

Copper reserves

Hypogene Sulphide Ore Reserves at Spence

BHP confirms the inclusion of significant additional Hypogene Sulphide Ore Reserves to the Spence declaration, and minor increases to the oxide and supergene sulphide reserves previously declared as at 30 June 2017.

The declaration of Hypogene Sulphide Ore Reserves (including minor contributions of transitional sulphide material) reflects the approval of capital expenditure (US$2.46 billion) by BHP on 17 August 2017 for the construction of a concentrator and associated infrastructure at Spence. The Spence pit expansion to exploit the deeper hypogene material has resulted in a minor increase in Ore Reserves for the oxide and supergene sulphide ore types declared as at 30 June 2017. The Spence Growth Option (SGO) project has been assessed as technically achievable and economically viable.

The Spence Hypogene Sulphide Mineral Resources and Ore Reserves are a downward, continuous extension of the currently exploited Supergene Oxide and Sulphide Mineral Resources and Ore Reserves. The supergene oxide and sulphide material is currently processed in a leaching operation whereas the hypogene sulphide material will provide ore feed to a conventional sulphide milling and flotation concentrator plant.

The Spence deposit is centred on porphyry bodies that have intruded sedimentary and volcanic units. Vertically extensive hypogene chalcopyrite with or without molybdenite mineralisation is overprinted by supergene sulphide chalcocite with or without covellite mineralisation. The supergene sulphides are locally oxidised to a copper oxide assemblage. The contact between the supergene and underlying hypogene sulphide zones is transitional.

Reserves are estimated incorporating operational parameters, geotechnical constraints, costs and commodity prices as defined by BHP. Optimal pushback designs are developed by incorporating mine operational aspects, plant capacity, loading equipment and ore exposure to produce a mining production plan. The selection and design options take into account both processing route alternatives and are based on the optimal economic sequence according to operational restrictions. The current and future SGO project fleet size is estimated based on the optimal production levels to maximise the net present value given the existing infrastructure and geotechnical parameters.

Ore Reserves classification reflects the Mineral Resources classification, along with consideration of any uncertainties in relation to modifying factors. Key modifying factors, incorporating Spence's processing alternatives and unit capacities are copper content, mineral hardness, comminution and processing rates, and metallurgical recovery by plant. Approximate drill hole spacing, which is indicative of reserve classification, is presented in the table below.

The main economic driver for the planned process routes of supergene (leach) versus hypogene (concentrator) is based upon copper mineralisation species, refined by copper cut-off grade. The cut-off grades used to differentiate waste from mineralisation are 0.20 per cent total copper for the supergene, transitional and hypogene sulphide material for concentrator processing and 0.30 per cent total copper for the supergene sulphide and oxide material for heap leaching. These cut-off grades are based on break-even economic analysis and assume open-pit extraction (15m bench height).

Copper in supergene oxide and sulphide mineralisation is currently recovered through heap and dump leaching and a solvent extraction and electrowinning plant. The construction of the SGO project facilities will add a new processing route, sulphide flotation and concentration of the hypogene copper sulphides (chalcopyrite) which are refractory to heap leaching technology. These facilities include: a primary crusher, a semi-autogenous grinding mill, two ball mills, a sulphide froth flotation plant and tailings storage facilities, combined with concentrate export and sea-water desalination and process water delivery facilities. The concentrator plant will generate molybdenum as a separate concentrate product stream, along with gold and silver credits in the copper concentrate.

Concentrator metallurgical recoveries of between 82 and 91 per cent of total copper have been informed on the basis of extensive laboratory and pilot testwork. Studies indicate that arsenic content within the deposit can be managed to minimise product contamination risk. The revised Ore Reserves estimate for Spence as at 17 August 2017 is presented in the table below.

Table Footnotes:

1) These Ore Reserves were estimated by C González (MAusIMM) and are an update to Ore Reserves reported by F Barrera (MAusIMM) for the year ended 30 June 2017 in the 2017 BHP Annual Report which can be found at www.bhp.com. Both Mr González and Mr Barrera are full time employees of BHP and have sufficient experience that is relevant to the style of mineralisation and type of deposit under consideration and to the activity which they are undertaking to qualify as Competent Persons as defined in the 2012 Edition of the 'Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves'. C González and F Barrera consent to the inclusion in this report of the matters based on the form and context in which they appear.

2) This is a first time Ore Reserves estimate declaration for Spence Transitional and Hypogene Sulphide Ore Types and revised estimate for other Ore Types. The Ore Reserves are supported by a forward-looking copper commodity price protocol based on supply and demand assumptions.

3) Ore Reserves are estimated as dry metric tonnes, on the basis of ore delivered to the process plant.

7

4) The revised Spence Reserves Life is estimated as 40 years based on the current stated Ore Reserves estimate divided by the current approved nominated production rate as at 17 August 2017.

5) The Ore Reserves tabulated are held within existing, permitted mining tenements. BHP's mineral leases are of sufficient duration (or convey a legal right to renew for sufficient duration) to enable all reserves on the leased properties to be mined in accordance with current production schedules. Our Ore Reserves may include areas where some additional approvals remain outstanding, but where, based on the technical investigations we carry out as part of our planning process and our knowledge and experience of the approvals process, we expect that such approvals will be obtained as part of the normal course of business and within the time frame required by the current life of mine schedule.

Iron ore - Total iron ore production for the September 2017 quarter decreased by three per cent to 56 Mt, or 64 Mt on a 100 per cent basis. Guidance for the 2018 financial year remains unchanged at between 239 and 243 Mt, or between 275 and 280 Mt on a 100 per cent basis, with volumes weighted to the last three quarters of the year.

WAIO production for the September 2017 quarter was lower, as expected. Record production at Jimblebar was more than offset by the impact of lower opening stockpile levels, following the fire at the Mt Whaleback screening plant in June 2017, and planned maintenance in the September 2017 quarter. Mine productivity improved in the quarter as a result of increased plant availability and consistent feed rates. Stockpile levels have been rebuilt and are expected to be partially drawn down in the next quarter. Port debottlenecking activities will extend into the December 2017 quarter. BHP continues to work with the relevant authorities in relation to the necessary approvals to increase system capacity to 290 Mtpa (100 per cent basis).

Mining and processing operations at Samarco remain suspended following the failure of the Fundão tailings dam and Santarém water dam on 5 November 2015.

Metallurgical coal - Metallurgical coal production for the September 2017 quarter was flat at 11 Mt. Guidance for the 2018 financial year remains unchanged at between 44 and 46 Mt.

At Queensland Coal, mining operations have recovered following the impacts of Cyclone Debbie, with record production at Saraji and increased production at Peak Downs and Caval Ridge, underpinned by an improvement in trucking hours and utilisation of latent wash-plant capacity. This was offset by lower production at Broadmeadow due to difficult roof conditions.

The Caval Ridge Southern Circuit project is progressing according to plan, with production expected to ramp-up early in the 2019 financial year.

8

Energy coal - Energy coal production for the September 2017 quarter decreased by two per cent to 7 Mt. Guidance for the 2018 financial year is unchanged at approximately 29 to 30 Mt.

New South Wales Energy Coal production increased by seven per cent as it benefitted from improved stripping performance and additional bypass coal. This was offset by a 15 per cent decrease in volumes at Cerrejón, which was constrained following the impact of extreme wet weather at the end of June 2017.
