Probertite, the monoclinic P21/a (NaCa[B5O7(OH)4](H2O)3) was found in between -56 and -60 m in a drill core from Sorpresa claim, in Sijes, Salta. The mineral occurs as mm-sized crystals included in halite, or as partial centripetal replacement of small ulexite lenses included in halite. Probertite was formed after primary evaporitic ulexite by thermal diagenesis. Palabras clave: Probertita - Pertenencia Sorpresa - Sijes - Salta Key words: Probertite ? New occurrence ?
