The municipality shot to fame in December 2006, when a Brazilian maths teacher by the name of Ivani Valentim da Silva posted descriptions of miners scooping up thousands of dollars in gold in the area. In just three months, between 3,000 and 10,000 people poured into the area, cutting down trees, diverting streams and digging wildcat mines. The city was nicknamed Eldorado do Juma after the mythical El Dorado.
