Figure 4 indicates the contribution of small-scale gold mining to the total gold production in Tanzania. It can be observed that, the percentage of total gold production from small-scale mining has increased from 10% in 2012 to 30% in 2020. This may be attributed to the increase in the number of formal small-scale gold mining
