[Report describing how] thousands of children work in licensed and unlicensed small-scale gold mines...[risking] 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...Many children who work in mining are orphans or other vulnerable children who lack basic necessities and support. Human Rights Watch also found that girls on and around mining sites face sexual harassment, including pressure to engage in sex work. Some girls become victims of commercial sexual exploitation and risk contracting HIV or other sexually transmitted infections.
