In the zone oxidized a reservoir in the San Antonio de los Cobres Pb-Ag-Zn district. The Mimetite is with Malachite, Chrysocolla, Cuprite, Opal, Cerussite, Gypsum, Turquoise, Azurite, Covelline, Hemimorphite, Pyromorphite, and Descloizite.
The deposit is located 28 km south of San Antonio de los Cobres, SE of the Organullo prospect, in the middle stretch of the Toreca ravine.

In 1957, Compañía Minera La Poma SA began exploiting the deposit until 1969. Ore was treated in the plant of the Esperanza mine located west of San Antonio de los Cobres.
