Odc. 9: Zespół odkrywa opale przy tamie po zbadaniu odpadów nad brzegiem rzeki i źródeł kwarcu

Ruri is disappointed when a reported opal deposit turns out to be fully mined out. Record rains deliver cultural waste to the riverbank, along with unexpected quartz and pyrite. Nagi puts on an impromptu fashion show. The team returns to the river. They search upstream and discover the source of the quartz and pyrite. Further on, at a dam site, they find plentiful opals concentrated by water flow. (Source: Wikipedia)
