About the locality
In April 1995, before the famous San Andrés (Espiel) find, a small group of amateurs revisited Roman lead workings in the Resuperferolítica concession (Solana de la Canaleja, Santa Eufemia) and opened a very localized zone where cavities lined with pyromorphite appeared, with well-defined hexagonal prismatic crystals in characteristic yellowish-brown and honey-yellow tones, sometimes with a muted greenish tint; the species was already known in the district, but not with that aesthetic, and within a few weeks numerous pieces came out, many still labeled "04/1995," which quickly dispersed through fairs and collections, establishing that brief episode as the starting point of the modern Spanish classic.
