Suredaite is a rare tin and lead sulphide, which was recently discovered (in 2000). This mineral resembles much to teallite (PbSnS2).
Its crystals prismatic, tabular and are lengthened, sometimes almost acicular. Their color is gray-black with a metallic lustre.
The only locality currently known is the Pirquitas mine in the province of Jujuy in Argentina, which is thus its type locality.
The types of this species were deposited in the collections of the Institut für Mineralogie und Kristallographie of Vienna and in the collections of the Natural History Museum in London, United Kingdom.
