The West African Craton is an area of 4.5 million km2, extending across 14 countries in western Africa, which hosts significant gold resources, most often in orogenic deposits related to secondary structures (Figure 1). The craton consists of two Archean belts situated adjacent to Paleoproterozoic domains made up of greenstone belts, sedimentary basins and large shear zones. In the southern portion of the West African Craton, Birimian greenstone belts contain almost 20% of global gold resources and is the largest Paleoproterozoic gold-producing region.

Birimian Greenstone Belts host the majority of gold deposits in Burkina Faso, Côte d’Ivoire, Ghana, Guinea, Mali and Senegal, with over 300Moz of resources discovered. Burkina Faso has known gold endowment of +60Moz (Figure 2), with the majority of gold discoveries made in the past 15 years.

Arrow holds a 100% interest in 12 exploration licences and two exploration licence applications, totalling 2,013km2, across six gold projects in Burkina Faso (Figure 3). The most advanced project is Divole, where target generation and first pass drilling has been completed.
