Summary:
The Republic of Guinea is located in the southern part of the West African craton. Guinea has a rich and varied mining potential with reserves estimated of several billion tonnes of bauxite and iron ore, plus gold, diamonds, and base metals. The gold ore occurs as secondary (alluvium beds and terraces of rivers) or primary (veins, quartz veins) deposits. The major gold deposits are located in the Birimian Domain in Upper Guinea, and current annual production is about 8 to 10 tons of gold, divided between small-scale miners and industrial companies. The four main known gold metallogenic areas of Guinea include (i) the Siguiri Basin of Upper Guinea (Kankan, Siguiri, Kouroussa, Mandiana) and Dinguiraye; there are lateritic and/or saprolitic deposits or indications of gold-bearing quartz veins and stockworks; (ii) the Siguiri Basin of savanna Guinea (Kankan, Siguiri, Kouroussa, Mandiana); (iii) the Kouroufing (Mamou and Kerouané) and Beyla areas located in the southeast also have auriferous quartz veins; and (iv) primary deposits of N’Zérékoré sheet NZE-Q2 (Au), coordinates 8° 12’ to 8° 08’ W longitude and 7° 40’ N latitude (Kogota-Guipo), hosted in amphibolite gneisses; Au and Ag of 1.25 to 2.1 g/t and 3.45 to 41.3 g/t, respectively. The primary deposit NZE-zone Q3 (Au) has coordinates 8° 26’59’’ longitude W and 7° 37’30’’ latitude N; the orebody is characterized by tuffites with hematite. These lithologies are located in Lower Proterozoic and Archean domains. In these areas, th ........
