Thanks for the link Jordi. There seems to be quite a lot of variation in the color and texture of the coatings, so I wonder if any of the other specimens have been analyzed. According to Mindat, all four minerals apparently occur as coatings on stibnite from this locality. I now suspect that each specimen must be analyzed to know for sure what the coating is.
