Iron ballast recovered from the Sao Jose slave ship wreck. The ballast helped to weigh down the slave ship and its human cargo.

Between 2010 and 2011, Iziko Museum archaeologist Jaco Boshoff discovered an account of the wreck lodged by the captain of the ship, which rekindled interest in the site.

Copper fastenings and copper sheathing were also uncovered. It's believed that the fastenings held the structure of the ship together and the sheathing provided exterior protection.
