The mine covers an area of {{convert|7.64|km2|sqmi}}. It has an indicated nine million tones of ore with 1.89% copper and 0.60% cobalt. Mining in the Tilwezambe pit has taken place off and on since 1999. At first this was done by the state-owned Gécamines using contract labor. For a while, artesanal miners took over. In March 2004, Dan Gertler International and Beny Steinmetz Global founded a firm named Global Enterprises Corporate (GEC). In May 2004 GEC signed a preliminary agreement with Gécamines, finalized in September that year, to rehabilitate and operate the Kananga and Tilwezembe mines. The deal was ratified by presidential decree.[1] In January 2008 Katanga Mining finalized acquisition of Nikanor PLC for $452m.[2] A joint venture of Katanga Mining (75%) and Gécamines (25%) began mining in 2007. In November 2008, Katanga Mining said they had temporarily suspended mining and ore processing at the Kolwezi concentrator due to the depressed price of cobalt.[3] References1. ^{{cite web |url = http://www.mineweb.net/mineweb/view/mineweb/en/page36?oid=19037&sn=Detail |title = Nikanor's DRC mining contract quandary |author = Barry Sergeant |date = 3 Apr 2007 |accessdate = 2011-11-16 |deadurl = yes |archiveurl = https://web.archive.org/web/20111121003528/http://www.mineweb.net/mineweb/view/mineweb/en/page36?oid=19037&sn=Detail |archivedate = 21 November 2011 |df = }} 2. ^{{cite web |url = http://www.katangamining.com/kat/about_us/history/ |title = History |publisher = Katanga Mining |accessdate = 2011-11-16 |deadurl = yes |archiveurl = https://web.archive.org/web/20111110080329/http://www.katangamining.com/kat/about_us/history/ |archivedate = 2011-11-10 |df = }} 3. ^{{cite web |url=http://www.infomine.com/index/pr/PA698481.PDF |title=Kolwezi Concentrator Update |publisher=Katanga Mining |date=November 21, 2008 |accessdate=2011-11-06}} }} 5 : Copper mines in the Democratic Republic of the Congo|Cobalt mines|Katanga Province|1999 establishments in the Democratic Republic of the Congo|Cobalt mining companies |
