Mutanda’s own sourced copper production of 96,500 tonnes was 12,400 tonnes (11%) down on H1 2016, reflecting reduced throughput, following unusually severe wet weather earlier in 2017. H1 cobalt production of 11,200 tonnes was 300 tonnes (3%) higher than H1 2016, reflecting upgrades to the plant completed during 2016.
Mopani’s own sourced production of 15,000 tonnes was 6,300 tonnes (30%) down on H1 2016, reflecting a 45 day smelter shutdown in May/June. Mopani continues to produce at reduced rates while the new shaft projects are completed.
Glencore’s share of copper production of 108,600 tonnes was in line with H1 2016.
The mine is currently accessing a higher portion of copper/zinc ores and less copper only ores. As such, Glencore’s share of copper production at 70,300 tonnes was 9% down on H1 2016, however increased zinc production of 59,000 tonnes was 171% higher.
Other South America
Copper production of 160,800 tonnes was 24,600 tonnes (13%) down on H1 2016, reflecting lower grades / pit wall stability issues at Alumbrera as it approaches end of life, and expected transition to lower copper grades at Antapaccay. Gold production of 163,000 ounces was 8,000 ounces (5%) down, mainly relating to Alumbrera, partly offset by improved gold grades at Antapaccay.
Own sourced production of 116,400 tonnes was 8,200 tonnes (7%) down on H1 2016, mainly reflecting the sale of a 30% economic interest in Ernest Henry in Q4 2016.
Custom metallurgical assets
Copper cathode production of 259,500 tonnes was 17,900 tonnes (7%) up on H1 2016, reflecting a more stable performance from Pasar, which was ramping up during the base period, post its smelter upgrade and expansion. Copper anode production of 264,300 tonnes was in line with H1 2016, as improved production at Pasar was offset by lower feed grades and timing of planned maintenance shutdowns at Altonorte and Horne.
