Throughout Africa artisanal and small-scale mining, whether legal or illegal, has been associated with social problems such as conflict, environmental damage, health risks and child labour. Although there are no exact numbers of how many people participate in such mining activities, it is evident that it is widespread.
Despite its negative aspects, the contribution of small-scale mining to the resource sector and social development cannot be disputed. About 15% to 20% of the world’s non-fuel mineral production comes from this sub-sector. An example of this can be seen in Ghana, where small-scale mining has contributed US$460 million since 1989 and is estimated to employ 300,000 to 500,000 individuals.
In South Africa, illegal mining as it currently stands covers all aspects of unpermitted mining. But this definition does not allow for differentiation between invasive illegal mining and informal community miners. Invasive mining occurs when miners illegally enter the old mine workings of decommissioned mines. Informal mining is community based mining that typically follows customary law.
