About the locality
In April 1995, an amateur find at the Resuperferolítica concession (Santa Eufemia) brought to light spectacular honey- and brown-toned pyromorphites. Extracted over just a few weeks and typically labeled "04/1995," these specimens rapidly spread throughout the mineral community, establishing this brief event as the start of the modern Spanish classic. Inactive now.
