They are located on a stretch of shore known as Ponta das Lajes, near where the Rio Negro and the Solimões river flow into the Amazon.

The rocky point is called Ponto das Lajes on the north shore of the Amazon near where the Rio Negro and Solimoes rivers join.

The mill takes 129 million litres of water a day from the local river, the Rio Negro.
