Name and Location
Kipoi copper project, Democratic Republic of Congo (DRC).

Client
Tiger Resources (60%) and La Générale des Carrière et des Mines (40%).

Project Description
The Kipoi project covers 55 km² and is located 75 km north-north-west of the city of Lubumbashi, in Katanga. The project contains a 12 km sequence of mineralised roan sediments that host at least five known deposits – Kipoi Central, Kipoi North, Kileba, Judeira and Kaminafitwe.

Joint Ore Reserves Committee-compliant resources have been reported at three of the deposits. The principal deposit is Kipoi Central, which contains a zone of high-grade copper mineralisation within a much larger, lower-grade global resource.

Tiger is taking a phased development approach at the project.

The high-grade zone of copper mineralisation at Kipoi Central is being exploited during the Stage 1 development. During the three-year operation of Stage 1, an estimated 900 000 t/y of 7% copper is planned to be processed through the heavy-media separation (HMS) plant, with a recovery rate of 55% to produce 132 000 t of copper in concentrate over its 42-month life.

The existing infrastructure at Kipoi for the Stage 1 HMS facility will be a springboard for the development of the Stage 2 solvent extraction electrowinning (SX-EW) plant, thereby minimising costs for the Stage 2 development. It is envisaged that ore from the Judeira deposit, and other deposits within the Kipoi project area and the nearby 100%-owned Lupoto project, will also be processed during the Stage 2 operations, providing additional returns and increasing the mineral resources available as feedstock to the Stage 2 SX-EW plant. Increased resources will potentially increase the nine-year mine life, demonstrated in the feasibility study and/or yearly plant throughput.

The HMS plant is producing more than 36 000 t/y of copper in a 25% concentrate. After a short period, during which the HMS and SX-EW facilities will operate simultaneously, the HMS will be superseded in the second quarter of 2014 by the SX-EW plant, which will produce London Metal Exchange grade-A copper cathode directly at the mine site.

The SX-EW plant is expected to produce 25 000 t in its first full year of operation and 50 000 t in subsequent years.

Value
Stage 1 cost an estimated $30-million.

Stage 2 will cost $160.9-million.

Duration
The Stage 2 SX-EW plant is scheduled to come on stream in 2014.

Latest Developments
Tiger reached commercial copper cathode production at its Stage 2 SX-EW plant, at the Kipoi project, in July.

Tiger produced 1 501 t of copper cathode, operating at 72% of the 25 000 t/y nameplate capacity. For commercial production to be reached within six weeks of startup is a significant achievement, as it can often take more than six months to bring an SX-EW plant to full production.

The plant is expected to produce about 14 000 t of copper cathode in this calendar year and a further 25 000 t of cathode in the first full 12 months of production.
