In pictures: Brazilian gold mine

There was a time when the only women found in such gold mines were prostitutes.

In ElDorado do Juma, there are around 100 women – some working in the sex trade but others working as merchants and “housekeepers” looking after miners’ tents.

And some like Marinete, 25, are gold miners themselves.

She is working in one of the “igarapes” – the little streams off the main river, washing the mud and stones in the search for gold.
