Company founded in 1984 to regain control of mines in the Kafubu district.
Apparently "Africa's largest emerald mine" (Elements 5 (2009) p. 157). 15-20% of the emerald world production comes out of this mine (Behling, 2009).

The mine covers an area of 1 square km.
Emerald crystals of very high quality are extracted from quartz lenses.
