| The gold collected at Achin comes partly from the mountains in the neighbourhood but chiefly from Nalabu and susu. |
| The first is the Mande language group, which resembles Mandinka in structure, and includes Mende, Susu, Yalunka, Koranko, Kono, and Vai. |
| In Ghana, Barclays works with susu collectors, who gather money from small-scale market traders and keep it safe for them for a fee. |
| An iteration of communal lending, susu, is, however, known to have originated from Nigeria and spread to Ghana in the early part of the 20th century. |
| In West Africa, susu or esusu collectors provide access to credit as well as the possibility to save and withdraw money for a small fee. |
| Over the next two centuries, the Susu gained control of the coast by building a series of small states based on clan and town affiliation. |
