The Diakha (Seguekho) concession consists of 500 hectors, equivalent to 1275 acres and is in eastern Senegal, in the Kedougou region 10 kilometers north of the village of Boussankhoba. The mine is accessible from National road 7 via dirt road.
From a geological perspective, the exploration and geological work performed is in Eastern Senegal, in the South Eastern conner of Kedougou-Keniega.
The Seguekho area contains a large deposit of alluvial gold and a diamond deposit estimates of l.5 million gem quality and industrial diamonds formed during the Birimian era between 2.05 billion and 2,100 billion years. The deposit formed from the destruction of rocks that were transported by water from rivers or gold finishes by the deposit in the form of tiny particles. As result, troves of veins of quartz formed in the area.
Several studies have been carried out in the southeastern part of Senegal by the Bureau of Research and Geological Mining (BRGM) the Russians and the UN Development Program (UNDP).
