There are between 11-15 Fairtrade-certified mines (this number can change often, but there are 11 very safe ones, others sometimes do not renew their license or have just started). And then there are currently 10 Fairmined certified mines (again, the number changes as sometimes mines are added or do not renew their license). 

Please also be aware that the certified mines are just the tip of the iceberg, there are many more mines the non-profit organisations Fairmined and Fairtrade work with in order to help them on their path towards responsible mining.
