Paso Yobai
Paso Yobai is the largest and easternmost district of the Guairá Department, Paraguay. It  was founded in 1923 by the Swiss (Geneva) colonist George Naville (1877-1943). Paso Yobai was governed as part of the district of Independencia until 1993, when it was granted independence by the central government. The largest town in the district is also named Paso Yobai, and contains around 2,500 people. Paso Yobai is historically known for the high quality of its production of yerba mate (ilex paraguariensis). Is also known for the production of sugar-cane, cotton and soy. The Canadian company "Latin American Minerals, Inc." bought "Paraguayan Mines" in 2007 and negotiated an agreement with the Paraguayan government to begin mining in the district. The company believes that Paso Yobai may contain one of the largest gold veins of the world. Although mining has brought increased prosperity to Paso Yobai, it has also brought environmental problems, the most serious being mercury contamination in the streams. The harpist, Enrique Samaniego was born in Paso Yobai. Economy 
Until recently the production and processing of yerba mate was the dominant economic activity in the district of Paso Yobai. At one time yerba mate cultivation covered 10,000 hectares of territory. Presently there are 8,000 hectares under cultivation, and gold mining has replaced yerba mate as the most lucrative economic activity. Still, yerba mate is extremely important to the local economy. Several factories in the district process yerba mate and produce brands such as Sudetia and Labrador. While the cultivation of yerba mate, sugar cane, soybeans and other crops is still of great importance to the district, the discovery of gold encouraged many people to abandon agriculture in order to devote themselves to small scale mining. The recent presence of the Canadian company is a source of both fear and expectation. Many think that it will create good paying work and but others worry about whether they will be able to continue their small scale mining activities as the company expands its presence in the zone. Gold mining 
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 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 talent 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 creeks. Arroyo Gasory, Paso Yobai's largest creek, is now highly contaminated with mercury and the fish are unsafe to eat. Patronage Festival (Fiesta Patronal) 
One of the most important celebrations in Paso Yobai is the Patronage Festival (Fiesta Patronal), celebrated every August 15 honoring its saint patron, the Virgin of Our Lady Saint Mary of the Asunción. The festivities start with the novena each afternoon, with every neighborhood organizing one day of it. Also, on the lawn of the Catholic Church there is a religious chorus competition. People come from throughout the district to participate in this celebration. On the morning of the 15th there is a procession with the image of the Virgin on the streets Paso Yobai, which are decorated with arcs of bamboo and paper strings. The procession proceeds to the church where the local parish priest begins the celebratory mass. After the Mass, the celebration continues with bullfights and music. Borders of Paso Yobai
