Brazil’s government has announced that starting July 3 it will require electronic tax receipts for the buying and selling of gold in a move to crack down on illegal mining in the Amazon.
Currently, gold is sold with paper receipts based on the “good faith” of the seller, making it often impossible to trace its origin.
Between 2015 and 2020, Brazil traded 229 tonnes of gold with evidence of illegality, equivalent to almost half of the gold produced and exported by the country, according to a report from NGO Instituto Escolhas.
