In pictures: Brazilian gold mine

One way to make money – tough but not as back-breaking as mining– is to provide goods and services for the miners.

There are about 50 shops – many of them selling drink – that can bring their owners big profits.

A bottle of Brazilian liquor, cachaca, sold for $2.50 in Sao Paulo or Rio costs $25 in Juma.

Some women like Jussara are more than willing to work from dawn until dusk in their shops.
