Las Colmenitas Mine, Santa Marta, Badajoz, Extremadura, Spain

Ancient lead-zinc mine.
Gonzalez Del Tanago et al. (2003) write on the Santa Marta deposit: "This deposit is located 2 km NW of Santa Marta village (6° 36' E, 38° 37' 45 N) in Las Colmenitas and Los Llanos mine (Muelas et al. 1977).

The type locality of calderonite may actually be the Reserva Mine (see http://www.mindat.org/mesg-24-84247.html).

Note on the mineral list: Gonzalez Del Tanago et al. (2003) also mention unspecified "ubiquitous Ca-Fe carbonates".
