PERTH (miningweekly.com) − TSX- and ASX-listed Anvil Mining has produced its first copper cathodes at the Kinsevere stage two solvent extraction and electrowinning (SX-EW) mine, in the Democratic Republic of Congo (DRC).

The miner said in a statement that 36 t of copper cathode was harvested on May 4, with total copper cathode production amounting to around 230 t to date.

The SX-EW section of the operation has been fed by copper solution from both heap leaching and the first copper circuits, said Anvil.

“With the construction phase almost completed and commissioning progressing at a pleasing pace, the focus is firmly on the ramp-up to reach a production rate of 5 000 t of copper cathode a month,” said president and CEO Darryll Castle.

He noted that the commissioning and ramp up was an ongoing process that was expected to take several months, however, both the heap-leach circuit and the first SX circuit had now been handed over by the engineering, procurement and construction contractor, with commissioning expected to start this month.

Castle said that the company expected the commissioning to be substantially completed by the end of the second quarter, and it was anticipated that design capacity would be achieved during the fourth quarter of 2011.

Anvil initially planned to commission the plant in the first three months of the year, but said last year that there were some problems with getting key materials and equipment to the site, which resulted in construction delays.

The current Kinsevere processing operation produces some 16 000 t/y of copper concentrate, with the stage two SX-EW plant expected to produce some 60 000 t/y of copper cathode.
