Which goods drew Portuguese traders to the Mauritanian coast?

Portuguese traders were drawn to the coast of Mauritania primarily to secure gold, gum arabic, and slaves.1

Following their arrival at Cape Blanco in 1442, the Portuguese established a fort on the island of Arguin to facilitate this commerce and to intercept the western trans-Saharan trade. While the Portuguese initially hoped to control these trade routes, their efforts in the region were limited, and the fort at Arguin served as the primary base for their activities along the Mauritanian coast.21
