I'm with Ralph on this one and wondered whetehr it might be melanterite formed by oxidation of pyrite. Is there any pyrite on your specimen? I know that melanterite hasn't been recorded from Zacatecas but it could have formed if the specimen has been kept in damp or humid conditions. If it is melanterite then the easiest way to remove it is to carefully add your specimen to bath of water containing a couple of drop of household detergent (to lower the surface tension of the water which should help a lot in preventing delicate jamesonite crystals from being 'knowcked off' the specimen). If its mould then that's a bit more tricky. Just a thought..........

Ralph is very correct in that it could be a sulphate coating the specimen as a result of pyrite decay. If it is then follow Alan's advice. If it is mold, I have heard that Dow Scrubbing Bubbles works well on specimens to clean them up. Of course, test an unwanted sample first to see what will work.
Good luck!
