Back in 2001 I bought a nice item consisting of colorless calcite scalenohedra to about 15mm on a very thin matrix of sparkling, mostly intergrown metallic crystals. The locality was listed as Mina Santa Rosa, near Canazasas, Panama. When I finally got around to examining the piece through a loupe, I saw many sharp, free standing crystals and thought that a small fregment of the matrix might make a good micromount, if only I could identify the minerals. Here on Mindat, I found a listing for a Santa Rosa Au Mine in Panama but no more detailed information. Finally my question: does anyone out there know where I might find mineralogical information on this locality?
