This 96-page report describes how thousands of children work in licensed and unlicensed small-scale gold mines in Tanzania, Africa’s fourth-largest gold producer. They dig and drill in deep, unstable pits, work underground for shifts of up to 24 hours, and transport and crush heavy bags of gold ore. Children risk injury from pit collapses and accidents with tools, as well as long-term health damage from exposure to mercury, breathing dust, and carrying heavy loads. A 17-year-old boy who survived a pit accident told Human Rights Watch, “I thought I was dead, I was so frightened.”
