QUARTERLY OPERATIONAL REPORT MARCH 2017

Graham Kerr, South32 CEO said:

 

"Despite several operational challenges during the quarter, we increased our net cash balance by US$645M to US$1.5B.

 

"Having achieved the right balance of strength and flexibility, we announced a US$500M capital management program and subsequently commenced an on-market share buy-back in April.

 

"Consistent with our strategy to identify new opportunities through the drill bit, we entered into a strategic alliance with AusQuest. Under this agreement, we will pursue five early stage base metal opportunities in Australia and Peru. We have also entered into an option agreement with Trilogy covering the more advanced Upper Kobuk Mineral projects in Alaska and will initially test the extent of their high grade Bornite copper resource."

 

·      Increased net cash by US$645M to US$1.5B at 31 March 2017.

·      Announced a US$500M capital management program in line with our commitment to return excess cash to shareholders.

·      Maintained strong performance at our aluminium smelters and achieved an alumina hydrate production rate in excess of 4.6Mtpa (100% basis) at Worsley Alumina.

·      Increased ore production at South Africa Manganese to an annualised rate of 3.8Mwmt pa (100% basis) in response to favourable market conditions.

·      Delivered first ore from the higher grade La Esmeralda deposit at Cerro Matoso.

CORPORATE UPDATE

·      Our net cash1 balance increased by US$645M to US$1.5B in the quarter as working capital unwound and we received US$108M (South32 share) in distributions from our equity accounted investments. On 27 March 2017, we announced a US$500M capital management program and subsequently commenced an on-market share buy-back on 19 April 2017. ·      Following an underground fire and subsequent downgrade to FY17 production guidance, Cannington's Operating unit cost2, including Sustaining capital expenditure, is now expected to increase to US$155/t (previously US$141/t). Unit cost guidance for all other operations in FY17 remains unchanged and will require strong performance in the June 2017 quarter. ·      Capital expenditure of approximately US$420M (previously US$450M) is now expected in FY17, although the rate of spend is expected to increase in the June 2017 quarter as land is purchased in preparation for the Klipspruit Life Extension project. ·      We invested US$13.0M in exploration in the nine months ended March 2017 (US$2.1M capitalised). This includes US$1.7M at our equity accounted investments (US$1.0M capitalised). We explored for metallurgical coal, manganese and silver in Australia and nickel in Colombia. ·      Beyond our current portfolio, we are pursuing base metals opportunities in four countries, having entered into new agreements with AusQuest Limited and Trilogy Metals Inc. in March and April, respectively. Under the terms of the latter agreement, we will provide US$30M over three years to test the extent of the high-grade copper resource at Trilogy's Bornite deposit in the Ambler Mining District, Alaska. This funding will be paid in tranches of US$10M per annum, with the decision to proceed to year two and three subject to exploration results. Our exploration spend is now expected to be approximately US$30M in FY17.   Upstream production guidance (South32's share)  FY16 9M YTD17 FY17e Worsley Alumina Alumina production (kt) 3,961 2,904 3,965 Brazil Alumina Alumina production (kt) 1,335 997 1,320 South Africa Energy Coal3 Energy coal production (kt) 31,681 21,500 Revised ↓ 30,000 Domestic coal production (kt) 16,825 12,744 Revised ↑ 17,500 Export coal production (kt) 14,856 8,756 Revised ↓ 12,500 Illawarra Metallurgical Coal Total coal production (kt) 8,366 5,327 7,900 Metallurgical coal production (kt) 7,059 4,260 6,360 Energy coal production (kt) 1,307 1,067 1,540 Australia Manganese Manganese ore production (kwmt) 3,071 2,218 3,120 South Africa Manganese Manganese ore production4 (kwmt) 1,711 1,500 Subject to demand Cerro Matoso Payable nickel production (kt) 36.8 26.8 36.0 Cannington Payable silver production (koz) 21,393 12,277 Revised ↓ 16,500 Payable lead production (kt) 173 105 Revised ↓      135 Payable zinc production (kt) 79 57 Revised ↓        70

South Africa Energy Coal saleable production decreased by 11% (or 2.6Mt) to 21.5Mt in the nine months ended March 2017. Export sales and pit development at the WMC were impacted by heavy rainfall in the March 2017 quarter and FY17 production guidance has been revised accordingly to 30.0Mt (domestic coal 17.5Mt, export coal 12.5Mt). The depletion of existing pits and the delayed development of new mining areas at the WMC is expected to result in a further 2.5Mt reduction in production in FY18 to approximately 27.5Mt (domestic coal 16.0Mt, export coal 11.5Mt). While our budgeting process for FY18 is currently underway, we do anticipate a significant increase in Operating unit cost, including Sustaining capital expenditure, as a result of the temporary reduction in production and rise in sustaining capital expenditure at the WMC.

Illawarra Metallurgical Coal total saleable production decreased by 9% (or 509kt) to 5.3Mt in the nine months ended March 2017 as challenging ground conditions were encountered at Appin Area 9 and mining rates were moderated at Appin Area 7 to ensure gas concentrations were maintained at safe levels. Production in the March 2017 quarter was impacted by a longwall move at Dendrobium that was extended by four days and was slow to ramp-up as a result of challenging roof conditions. FY17 production guidance remains unchanged at 7.9Mt and requires a strong finish to the year. A longwall move at Appin Area 9 is scheduled for June.

A drawdown of inventory ensured sales in the nine months ended March 2017 exceeded production by 258kt. Sales in the March 2017 quarter also included a carry-over shipment from the December 2016 half year, as anticipated.

Australia Manganese saleable ore production decreased by 5% (or 114kwmt) to 2.2Mwmt in the nine months ended March 2017. Heavy rainfall and Tropical Cyclone Alfred led to lower production in the primary high grade circuit in the March 2017 quarter, although this was partially offset by strong performance within the Premium Concentrate ore (PC02) circuit which continued to operate at its annualised capacity of 500kwmt (100% basis). Our low cost PC02 fines product has a manganese content of approximately 40% which leads to both grade and product-type discounts when referenced to the high grade 44% manganese lump ore index. FY17 production guidance of 3.1Mwmt remains unchanged.

Saleable manganese alloy production decreased by 5% (or 5kt) to 106kt in the nine months ended March 2017 as an electrode upgrade was undertaken in January. The impact of the shutdown was offset by a drawdown of inventory, resulting in an increase of alloy sales in the March 2017 quarter. All four furnaces are expected to ramp-up to full capacity in the June 2017 quarter.

South Africa Manganese saleable ore production increased by 23% (or 281kwmt) to 1.5Mwmt in the nine months ended March 2017 as we responded to favourable market conditions by opportunistically increasing ore production. This included an annualised production rate of 3.8Mwmt pa (100% basis) in the March 2017 quarter as we continued to sell Wessels concentrate and use higher cost trucking to access export opportunities. We ceased trucking activity at the end of the March 2017 quarter as we responded to a change in market conditions.

The Wessels Central Block project was commissioned in the March 2017 quarter, as planned. The project will enable mining to relocate closer to critical infrastructure and lower production costs in the underground mine.

Manganese alloy saleable production decreased by 18% (or 12kt) to 56kt in the nine months ended March 2017 despite an improvement in furnace stability in the quarter. Metalloys continues to operate one of its four furnaces. Alloy sales in the March 2017 quarter were affected by the timing of shipments.

Cerro Matoso payable nickel production decreased by 1% to 26.8kt in the nine months ended March 2017. A reduction in furnace availability in the March 2017 quarter was offset by the availability of previously stockpiled, higher grade fines.

The accelerated development of the higher grade La Esmeralda deposit allowed first ore to be delivered to the plant in the March 2017 quarter. Payable nickel production guidance remains unchanged at 36kt in FY17 but will rise to approximately 41.6kt in FY18 as La Esmeralda ramps up to full capacity.

Cannington silver, lead and zinc saleable production decreased by 25%, 22% and 5%, respectively, in the nine months ended March 2017 due to lower feed grades, consistent with the mine plan.

Remediation work to repair load-out and shaft haulage infrastructure damaged by an underground fire in April is continuing. FY17 production guidance was previously revised to 16.5Moz of silver, 135kt of lead and 70kt of zinc as mill throughput will remain constrained while this work is undertaken and the extraction of the higher grade (silver/lead) 60L stope is delayed. An Operating unit cost, including Sustaining capital expenditure, of US$155/t (previously US$141/t) is now expected in FY17 given the operation's high fixed cost base.

The development of the replacement underground crusher remains on schedule for commissioning in the March 2018 quarter. As previously indicated, the rate of deformation in the existing crusher chamber has increased and it may become inoperable earlier than planned. As such, the rate of ore extraction and metal production may become temporarily constrained by trucking capacity within the decline. We continue to monitor the rate of deformation and will provide updated production guidance when we report our FY17 financial results.

 

Notes:

1.     Provisional unaudited net cash balance as at 31 March 2017.

2.     FY17 Operating unit cost guidance, including Sustaining capital expenditure, and Sustaining capital expenditure guidance, include royalties (where appropriate) and the influence of exchange rates, and are predicated on various assumptions for H2 FY17, including: an alumina price of US$316/t; an average blended coal price of US$146/t for Illawarra Metallurgical Coal; a manganese ore price of US$6.79/dmtu for 44% manganese product; a nickel price of US$4.65/lb; a thermal coal price of US$84/t (API4) for South Africa Energy Coal; a silver price of US$17.04/troy oz; a lead price of US$2,267/t; a zinc price of US$2,746/t; an AUD:USD exchange rate of 0.75; a USD:ZAR exchange rate of 14.20; and a USD:COP exchange rate of 2,943; all of which reflected forward markets as at January 2017 or our internal expectations.

3.     8% of South Africa Energy Coal is owned by a Broad-Based Black Economic Empowerment (B-BBEE) consortium. The interests owned by the
B-BBEE consortium were acquired using vendor finance, with the loans repayable to South32 via distributions attributable to these parties, pro rata to their share in South Africa Energy Coal. Until these loans are repaid, South32's interest in South Africa Energy Coal is accounted at 100%.

4.     Consistent with the presentation of South32's segment information, South Africa Manganese ore production and sales have been reported at 60%. The Group's financial statement will continue to reflect a 54.6% interest in South Africa Manganese ore.
