Kongsbergite (Mercury rich Silver). NA68E1: In the classic mine of Las Herrerias recent activity has exposed an enriched zone where Silver was then found. These are similar to the samples found years ago, which are present in many of the most important museums worldwide. The latest specimens have a high (±10%) content of Mercury and some of them are on a matrix of red Jasper. Analysis has shown that they have a large amount of Chlorargyrite throughout the specimen.
