BHP copper production increased by 12 per cent to 834 kt
BHP has reported that total copper production increased by 12 per cent to 834 kt. Guidance for the 2023 financial year remains unchanged at between 1,635 and 1,825 kt.
Escondida copper production increased by five per cent to 511 kt primarily due to higher concentrator feed grade of 0.79 per cent, compared to 0.72 per cent in the December 2021 half year. The higher grade was partially offset by lower throughput and the impact of road blockades across Chile in the December 2022 quarter, which reduced availability of some key mine supplies.
Full year production is trending towards the low end of the guidance range of between 1,080 and 1,180 kt as a result of lower than expected concentrator feed grade and throughput. Production is weighted to the second half of the year, with concentrator feed grade expected to improve compared to the December 2022 half year.
Medium term guidance of 1.2 Mtpa of copper production on average over the next five years remains unchanged.
Pampa Norte copper production increased by eight per cent to 147 kt reflecting the continued ramp up of the Spence Growth Option (SGO). Guidance for the 2023 financial year remains unchanged at between 240 and 290 kt.
The SGO plant modifications started in August 2022 and are planned to be completed in the 2023 calendar year. Expected capital expenditure for the works remains unchanged at approximately US$100 million. Further studies are ongoing for additional capacity uplift at SGO. Cerro Colorado continues to transition towards planned closure at the end of the 2023 calendar year.
At Spence, BHP continues to closely monitor previously identified Tailings
Storage Facility (TSF) anomalies. We have reduced the volume of water in the tailings facility and continue to work with the local regulatory agencies, including on the implementation of a remediation plan for the TSF.
The SGO concentrator continues to operate with no impact to production or market guidance. Spence is expected to reach an average of approximately 270 ktpa of production for four years (including cathodes) following the completion of the SGO plant modifications and remediation of TSF anomalies.
Olympic Dam copper production increased by 138 per cent to 104 kt primarily as a result of the major smelter maintenance campaign (SCM21) in the prior period.
Continued strong concentrator and smelter performance resulted in near record material milled and concentrate smelted in the half year. Record gold production was also achieved in the half year as a result of debottlenecking initiatives implemented in the prior year. Copper production guidance for the 2023 financial year remains unchanged at between 195 and 215 kt.
Antamina copper production decreased by three per cent to 72 kt reflecting lower copper head grades partially offset by higher throughput. Zinc production was flat at 63 kt reflecting lower zinc head grades offset by higher throughput. Guidance remains unchanged for the 2023 financial year, with copper production of between 120 and 140 kt, and zinc production of between 115 and 135 kt.
