El Ghaîcha
Open-pit gold mine.
Located in northern Mauritania approximately 300 kilometers north of the capital city Nouakchott and 162 kilometers east-southeast of the port city of Nouâdhibou, in a wadi called Khatt Atui.
The mine is on the El Ghaîcha mineral lease.
Developed originally by Rio Narcea Gold Mines Ltd. Red Back Mining B.V. began commercial production in January 2008.
The gold mine is now (2019) owned and operated by Tasiast Mauritaneie Ltd. S.A. which is wholly owned by Kinross Gold Corporation which has leases extending over an area of some 312 sq. km.
"Mineralization at Tasiast is predominantly hosted in a banded iron formation (BIF) that was altered and mineralized late during deformation and metamorphism. The rocks and mineralization are of Archean age and similar in style to deposits in comparable Archean terrains; for example Musselwhite in Canada." (http://www.rionarcea.com/s/Tasiast.asp)
"Gold occurs both in intensely altered BIF and in and around quartz carbonate veins and veinlets associated with pyrrhotite. Gold is typically located in around the sulfide grains or in the veins but only rarely within the grains. In late 2004, Rio Narcea completed 3,000 meters of drilling to test the depth extension of the high-grade zone beneath the main pit (Piment Central deposit) that was identified by drilling earlier in 2004. The drilling results suggest the potential of adding mineral resources amenable to underground mining which would further enhance project economics. The high-grade zone was traced to a vertical depth of 300 meters and remains open at depth." (http://www.rionarcea.com/s/Tasiast.asp)
