NEWS RELEASE IMMEDIATE Release Time Date 19 October 2021 23/21 BHP Release Number BHP OPERATIONAL REVIEW FOR THE QUARTER ENDED 30 SEPTEMBER 2021 Note : All guidance is subject to further potential impacts from COVID - 19 during the 2022 financial year . • We safely delivered reliable operational performance during the quarter as we executed a series of planned major maintenance activities across our assets . All production and unit cost guidance ( ¹ ) remains unchanged for the 2022 financial year . Our major projects under development are tracking to plan , with two new projects , the Jansen Stage 1 potash project and the Shenzi North development project in the US Gulf of Mexico , approved during the September 2021 quarter . The Jansen shaft project is 96 % complete , and the Trion oil project in Mexico moved into the Front End Engineering Design ( FEED ) phase and is expected to progress to a Final Investment Decision from mid - calendar year 2022 . • The announced agreement to pursue a proposed merger of our Petroleum business with Woodside to create a global top 10 independent energy company is progressing to plan , with full form transaction documents expected in November 2021 . We announced our intention to unify our corporate structure under BHP's existing Australian parent company subject to final Board and other approvals . Unification would create a simplified structure and enhance strategic flexibility . If approved , unification is expected to occur in March 2022 quarter . • In Petroleum , the Calypso appraisal well Bongos - 3 in Trinidad and Tobago spud on 27 July 2021 and encountered hydrocarbons . A side track is currently being drilled to complete the appraisal . In Copper exploration , BHP exercised its option to form an exploration joint venture with Red Tiger Resources for the Intercept Hill copper project , which borders BHP's Oak Dam site in South Australia . Production Petroleum ( MMboe ) Copper ( kt ) Iron ore ( Mt ) Sep Q21 Sep Q21 Sep Q21 vs Jun Q21 commentary ( vs Sep Q20 ) ( vs Jun Q21 ) 27.5 3 % 376.5 ( 9 % ) 63.3 ( 4 % ) Metallurgical coal ( Mt ) 8.9 ( 9 % ) Energy coal ( Mt ) 4.2 17 % Nickel ( kt ) 17.8 ( 20 % ) 27.5 Higher volumes due to increased production from Ruby and higher seasonal gas 2 % demand at Bass Strait , partially offset by lower production at North West Shelf and natural field decline . 376.5 Lower volumes at Olympic Dam due to the commencement of the planned smelter ( 7 % ) maintenance campaign , albeit approximately one month delayed due to COVID - 19 related border restrictions . 63.3 Lower volumes reflects planned major maintenance including car dumper one and the ( 3 % ) impacts of temporary rail labour shortages due to COVID - 19 related border restrictions , which have improved during September 2021 . 8.9 Lower volumes due to planned maintenance at BMA , a planned longwall move at ( 25 % ) Broadmeadow and mining in higher strip ratio areas at BMC . This was partially offset by record stripping at BMC reflecting a step up in underlying truck productivity at South Walker Creek . 4.2 Lower volumes at NSWEC due to mining in higher strip ratio areas , partially offset ( 6 % ) by increased stripping enabled by continued improvement in underlying truck productivity . 17.8 Lower volumes due to planned maintenance across the supply chain . ( 21 % ) Group copper equivalent production decreased by 5 % in the September 2021 quarter following lower minerals volumes largely a result of planned maintenance .
