ScienceDaily reports that the gold mining complex in the Eria river valley includes sophisticated hydraulic works diverting river water to the mines. The Las Médulas region in León is considered to be the largest opencast mine in the Roman Empire but the University team discovered that mining extended many miles to the south east to the Eria valley.
"The volume of earth exploited is much greater than previously thought and the works performed are impressive, having achieved actual river captures, which makes this valley extremely important in the context of Roman mining in the north-east of the Iberian Peninsula," said Javier Fernández Lozano, geologist at the University of Salamanca and co-author of a study on the mines published in the Journal of Archaeological Science.
