There are some historical gold pits, like Roda, Batatal, Caixão, Coração, das Moças and das Velhas.

It is one of the oldest cities of Goiás. Unlike many cities in the state of Goiás, Silvânia has a long history, beginning in 1774 when miners coming from Santa Luzia, present-day Luziânia, found gold in the region. Soon a small settlement, called Bonfim, was established. In 1943 Bonfim was renamed to Silvânia in tribute to a local figure, Vicente Miguel da Silva.
