Although rumors of gold had been floating for years in the area of Paso Yobai, only since the late 1990s have people actively begun mining. The gold rush began after an
Ecuadorian man met a young woman from Paso Yobai in
Asunción. The two got married, and the Ecuadorian discovered gold in a stream on his father-in-law's property. From there began the
Gold fever that changed the life of many families. Many locals call the small scale gold miners "garimpeiros". The steps needed to obtain the gold are varied and depend on the skills of the miner. Depending on their luck and the quality of the product, a miner might earn around 125,000
Guaranis per gram of gold powder. It generally takes between one and two days for a small scale miner to extract a gram of gold. But this gram is difficult to obtain. A garimpeiro can generally survive strictly of their mining activities if he can obtain 10 grams or more of gold a month. Miners use
mercury to separate gold from sand and clay. Unfortunately, the mercury often enters and contaminates watercourses. Arroyo Gasory, the largest stream, is now highly contaminated with mercury and the fish are unsafe to eat. == Local Festivities ==
