NEWS RELEASE Release Time IMMEDIATE Date 21 April 2021 05/21 BHP Release Number BHP OPERATIONAL REVIEW FOR THE NINE MONTHS ENDED 31 MARCH 2021 Note : All guidance is subject to further potential impacts from COVID - 19 during the 2021 financial year . Record production was achieved at Western Australia Iron Ore ( WAIO ) and record average concentrator throughput was delivered at Escondida . • Production guidance for the 2021 financial year remains unchanged for petroleum and iron ore . Copper guidance has increased to between 1,535 kt and 1,660 kt and reflects stronger than expected performance at Escondida . Metallurgical coal guidance has been reduced to between 39 and 41 Mt as a result of significant wet weather impacts during the December 2020 and March 2021 quarters . Energy coal guidance has been reduced to between 18 and 20 Mt as a result of significant weather impacts at New South Wales Energy Coal ( NSWEC ) and lower than expected volumes at Cerrejón . • Full year unit cost guidance ( 1 ) ( based on exchange rates of AUD / USD 0.70 and USD / CLP 769 ) remains unchanged for Petroleum and WAIO . Unit costs for Escondida have been lowered to be between US $ 0.95 and US $ 1.10 ( 1 ) per pound , reflecting strong production and lower deferred stripping costs . Unit costs for Queensland Coal have been increased to be between US $ 74 and US $ 78 ( 1 ) per tonne , reflecting lower expected volumes for the full year . The Bass Strait West Barracouta gas project achieved first production in April 2021 , and is on schedule and budget . Our major projects under development are also progressing to plan . The Ruby project in Trinidad and Tobago is progressing ahead of schedule and on budget , with first production on track for May 2021. South Flank is tracking well with commissioning activities planned for the June 2021 quarter and is on schedule for first production in the middle of the 2021 calendar year . Jansen Stage 1 project remains on track for Final Investment Decision in the middle of the 2021 calendar year . Production Mar YTD21 Mar Q21 Mar Q21 vs Dec Q20 commentary ( vs Mar YTD20 ) ( vs Dec Q20 ) Petroleum ( MMboe ) 75.8 ( 8 % ) Copper ( kt ) 1,232.7 ( 6 % ) Iron ore ( Mt ) 188.3 4 % Metallurgical coal ( Mt ) 28.8 ( 2 % ) Energy coal ( Mt ) 13.0 ( 26 % ) Nickel ( kt ) 66.6 19 % 25.4 Higher volumes reflect increased Shenzi working interest ( following completion of the 7 % acquisition in November 2020 ) and impacts from Hurricanes Delta and Zeta in the Gulf of Mexico in the prior quarter . This was partially offset by lower seasonal demand at Bass Strait . 391.4 Lower volumes primarily as a result of decreased throughput at Escondida , reflecting ( 9 % ) the impact of a reduced operational workforce due to the continuation of COVID - 19 restrictions , and lower concentrator feed grade . 59.9 Lower volumes at WAIO reflects weather impacts and planned Ore Handling Plant ( 4 % ) and stacker maintenance at Newman , partially offset by improved car dumper performance . 9.6 Queensland Coal volumes in line with prior quarter as operations continue to be 1 % impacted by significant wet weather events . 4.8 Higher volumes at Cerrejón as a result of a strike in the prior period , partially offset by 34 % lower volumes at NSWEC due to significant wet weather impacts and increased washed coal in response to reduced port capacity following damage to a shiploader at the Newcastle port . 20.4 Lower volumes largely as a result of planned maintenance undertaken at the Kwinana ( 15 % ) refinery . Group copper equivalent production was marginally lower over the nine months ended March 2021. Strong underlying operational performance was offset by the impacts of planned maintenance , natural field decline , copper grade decline and adverse weather .
