Production Stats

Q1 2014

Sulphide ore milled (000's tonnes) 2,701
Sulphide ore grade processed (%) 1.0
Sulphide copper recovery (%) 92
Mixed ore milled (000's tonnes) 1,316
Mixed ore grade processed (%) 1.1
Mixed copper recovery (%) 72
Oxide ore milled (000's tonnes) 1,923
Oxide ore grade processed (%) 2.2
Oxide copper recovery (%) 82
Copper production (tonnes) 70,549
Gold production (ounces) 39,734
  • Despite the harshest wet season experienced in Kansanshi’s operating history, overall copper production was 12% higher compared to Q1 2013, due primarily to higher volume of sulphide and oxide ore milled, and higher grade sulphide ore processed.

  • Sulphide concentrate production increased 50% compared to Q1 2013, primarily the result of processing higher grade ore from the pit and a maintenance shutdown during Q1 2013.
  • Mixed ore production decreased 33% as throughput was lower in favour of processing higher volumes of oxide ore.
  • Copper production from the oxide circuit was 15% higher than Q1 2013 with the benefit of the expanded oxide circuit, while also aiming to produce an increasing amount of copper cathodes from oxide ore. Feed grades were consistent with Q1 2013; however recovery rates were impacted by a change in the mineralogy of the oxide ore with a higher amount of insoluble copper treated.
  • Gold production was 8% higher than Q1 2013 as a result of an increase in gravity recoverable gold ("GRG") from enhancements in the gold processing plant and an increase in the gold content in the processed ore.
