BHPB announced that its total copper production decreased by three per cent to 1,245 kilo tonne. Guidance for the 2019 financial year remains unchanged at between 1,645 and 1,740 kilo tonne.

Escondida copper production decreased by six per cent to 848 kilo tonne as expected lower copper grades were partly offset by record concentrator throughput. Production guidance remains unchanged at between 1,120 and 1,180 kilo tonne for the 2019 financial year, with volumes expected to be towards the lower end of the range.

Pampa Norte copper production decreased by 11 per cent to 172 kilo tonne and reflects planned maintenance and a production outage at Spence following a fire at the electro-winning plant in September 2018, and the impact of heavy rainfall in northern Chile in February 2019 at both Spence and Cerro Colorado. This was partially offset by record ore milled at both operations after implementing maintenance improvement initiatives. Production guidance at Spence and Cerro Colorado remains unchanged for the 2019 financial year, at between 160 and 175 kilo tonne and 60 and 70 kt respectively.

Olympic Dam copper production increased by 22 per cent to 115 kilo tonne as a result of the major smelter maintenance campaign in the prior period, which was partially offset by an unplanned acid plant outage in August 2018. Following completion of the acid plant remediation works, surface operations ramped up between October 2018 and February 2019. Production guidance remains unchanged at between 170 and 180 kilo tonne for the 2019 financial year, with volumes expected to be towards the lower end of the guidance range.

Antamina copper production increased by five per cent to 110 kilo tonne due to higher head grades. Production guidance for the 2019 financial year remains unchanged at approximately 135 kilo tonne for copper and approximately 85 kilo tonne for zinc.
